Description
Technical field
The present invention relates to a kind of synthetic grass structure, this structure comprises the sheet substrate, and this substrate has and a plurality ofly is used for simulating natural sod from the extended fibrous formation thing of substrate.Above-mentioned synthetic grass structure itself can be used as product, and the particles filled material that is scattered here and there between the fibrous formation thing structure of simulation natural sod, is used for making fibrous formation thing to remain on a basic vertical position.
Background technology
Such technical scheme is open in for example US-A-5 958 527 or EP-A-1 158 099.Especially in the technical scheme that back one file is explained, particles filled material or filler are made by uniform substantially granular plastic substance.
Being considered to more and more can be as effective alternative of natural sod for synthetic grass structure noted earlier (no matter be that those can not be as the technical scheme of packing material (filler), or those can be used as whole technical schemes of aforementioned filler).Using alternative is because of different reasons (ambient conditions, violent use etc.), and has proved that the maintenance of natural sod is a key issue, and this is because maintenance can produce expense.For example, the above-mentioned synthetic grass structure of known use is built sports ground, as football field, five-a-side football field, Rugby field and tennis court.Such synthetic grass structure also can be used to build the motion runway.
Have to a certain degree approximate but under the basic situation, prepare and when laying above-mentioned synthetic grass, need to consider at least three types Fundamentals near reality.
At first, synthesizing careless shape preferably can be approaching as much as possible with natural sod.In other words, synthetic grass preferably can its character of not obvious exposure.For this reason, in case laid after the face of synthetic meadow, need repair by directly scrubbing frequently, purpose is the fibrillation effect that the blocking group bottom fiber forms thing, the blade of the similar as far as possible natural grass of feasible synthetic grass.Based on same purpose, in practice, existing people proposes and adopts in advance to form the technical scheme that thing prepares synthetic grass through the fiber that curls or texture (textureing) (according to the term that uses in spinning department at present) is handled.But this technical scheme has run into two kinds of difficulties.On the one hand, a plurality ofly use curling from the extended fibrous formation thing of substrate or textured yarn has produced a lot of technical difficulties in order to prepare to have.On the other hand and since this substrate be difficult to and in fact can not make filler spread to by curl or texture fibrous form in the dense net that thing constitutes, such substrate especially can not be used in combination with filler compositions.
The factor that needs the second aspect of consideration is a synthetic grass loss problem in use.In fact, under the situation that lacks natural sod regrowth mechanism, according to the power that the different condition of using and meadow zones of different are subjected to, synthetic meadow can produce extremely uneven loss (or, produce various changes at least).For the example that provides to understand easily, can be for example on the ground of playing soccer, be subjected to stronger active force easily in the centre in court and the peripheral region at goal, these zones are subjected to loss greatly than other zone as the close position of court centre with near the zone, next door at goal.Using under the synthetic turf condition of filler, what need to consider is that the power of some type may cause filler to be kicked out of from its fixing position.As a typical example be, the sportsman wears spikes, and utilize spikes be used for produce pretending firmly forward, or realize urgent the deceleration.Usually, consider that filler can be subjected to strong like this active force, the fiber of synthetic turf forms thing suitable fixation is not provided.
At last, it is closely-related with the laying of synthesizing the meadow face needing the 3rd factor of consideration.Particularly, when relating to the synthetic meadow face that uses filler, present way is at first to lay the sheet substrate, and this sheet substrate contains the fibrous formation thing of simulating natural sod, then particles filled thing is dispersed on the turf.
The above-mentioned construction of carrying out in " on the spot " can be subjected to the influence of multiple key factor certainly.For instance, when the dispersed particulates filler, at first preferably fiber is formed thing usually and intervene, make that they can keep vertical substantially position when scattering filler.This purpose is in order to make granular material begin to precipitate gradually from subaerial extreme lower position.And the quantification of the granular material that is precipitated on the unit area needs specific equipment, and generally also the professional will be arranged.When packing material is plastic polymeric material, also relate to other factor, for example when scattering filler and the factor of temperature correlation.
Summary of the invention
The purpose of this invention is to provide a kind ofly, overcome the technical scheme of above-mentioned key issue with accurate way.
According to the present invention,, just realized above-mentioned goal of the invention because the method for the technical characterictic of claim has been arranged.
The invention still further relates to corresponding synthetic turf.
Especially, technical scheme of the present invention makes can provide the synthetic grass that is very similar to natural sod on a kind of profile (no matter whether the use of filler can be found out), and need not extra processing such as above-mentioned repairing or fibrillation.
In second aspect, technical scheme of the present invention provides a kind of synthetic turf with excellent anti-mechanical load characteristic, and this is at first to consider when being used for sports, and synthetic meadow face can bear the mechanical load that sole produces.
In addition, in the building course of the synthetic meadow face that uses filler, technical scheme of the present invention makes the fiber of design form thing can simulate natural lawn, thereby can hold or keep particles filled thing.
Because at least two fundamental causes, above-mentioned factor is considered to important.
The first, because the load that the effect of mechanical force is for example applied by the sportsman of drift bolt footwear, even and may having been dug relevant phenomenon occurrence frequency with filler and can not eliminating fully of causing but also can considerably reduce.
Also have, technical scheme of the present invention can be before laying synthetic meadow face, dispersed particulates filler in the process of the synthetic meadow of processing face.Technical scheme of the present invention just can make this process become possibility in processing steps, thereby in factory, synthetic meadow bread lozenge substrate and particles filled thing, wherein the sheet substrate has the fibrous formation thing that is used for simulating natural sod, and particles filled thing is dispersed between the fibrous formation thing, and fibrous formation thing self then keeps quite vertical state.Compare with ground on the scene again dispersed particulates material after the sheet substrate of laying fibrousness formation thing, the dispersed particulates material can be with more accurate and more controllable mode realization in process.
Especially, technical scheme of the present invention can be when product leaves factory, obtain a kind of synthetic meadow face that comprises sheet substrate and particles filled thing, wherein the sheet substrate has fibrous formation thing, and particles filled thing is dispersed between the fibrous formation thing, and this synthetic meadow face dispatches from the factory with a kind of sheet form that is curled.
Thereby the operation of laying synthetic meadow face is just quite simple, only described synthetic meadow face need be opened and is routed on the ground to get final product, and need not any further operation.Carry out can relying in the above-mentioned lay-up operation synthetic meadow face, this is because synthetic grass needs to satisfy some productions and quality specifications in industrial preparation, and these standards are to adopt traditional laying method if not can not also being the standard that is difficult to reach fully.
The present invention can explain by non-restrictive example, and in conjunction with the accompanying drawings.
Description of drawings
Fig. 1 is the synthetic desirable vertical cut-away schematic view of grass structure of the present invention
Fig. 2 illustrates for the method for preparation synthetic grass structure shown in Figure 1
The specific embodiment
Synthetic meadow face shown in Figure 1 comprises sheet substrate 1, and this substrate is designed to be placed on time ground G, and under the common service condition of majority, this time ground is made up of the soil or the pitch mat of tamping, common mode lay synthetic turf with free lay on it.
Sheet substrate 1 can be made up of flaky plastic material, for example carries out the non-textile that rubbery is handled with latex such as SBR latex or polyurethane latex.For the substrate of just being discussed, connect one deck foamed material at it on the face of inferior ground G and be good, for example polyurethane base foamed material by the present invention.
Begin to protrude upward a plurality of fibrous formation things 2 from substrate 1, this formation thing is clump shape usually so that the blade of simulating nature turf better.
Fibrous formation thing 2 is fixed in the substrate 1 in the proximal end of representing with 2a, and its far-end extends upward length completely, and this length begins from the extension plane of substrate 1 to measure, and according to required application, this length is usually in the scope of 10-80mm.Certainly, the data that provide above only are indicative purely.
According to an important characteristic of the present invention, this can describe in detail in the back, and far-end 2b is not the form that presents complete straight line, but has the form of distortion or " curling ".
Thereby fibrous formation thing 2 is customized to clump shape, and it has the essential structure that can be defined as " tree sample ".
The feature that aforesaid " tree sample " formation thing configuration has has:
-stem or trunk portion, this part then is the form of whole straight lines near near-end 2a; And
-constituting the top of far-end 2b, it has the form of curling as the aforementioned.
Except the outward appearance of our the far-end 2b that will introduce thereafter, the general standard of building substrate 2 and fibrous formation thing 2 (be included as the near-end 2a that obtains fibrous formation thing 2 and fixedly secure form in substrate 1) is well known in the art, therefore no longer describe in detail at this paper, also because it is not too important to understanding the present invention.
Consider to constitute the material selection of fibrous formation thing 2, often tend to select polyolefine material, as polyethylene or polypropylene, or more in general, selection can be born any plastic material of extruding, spinning and/or stretching, so that obtain the fiber of simulation natural sod blade outward appearance.
The feature that above-mentioned material generally has is, in order to obtain multicolour, in the material that forms fibrous formation thing, add pigment, this material can be at an easy rate by pigment dyeing, even after synthetic meadow face was used longer a period of time, color can also be stablized maintenance.
Usually, except common " tree sample " configuration, extending the absolute and relative yardstick of the fibrous formation thing 2 that the right angle orientation on plane measures according to substrate 1, is not particular importance for enforcement of the present invention.No matter selected concrete scale-value is absolute or relative value, mainly is the purpose decision that is placed by discussion ground.
Illustrate purely, consider use, be used for the preferred thin turf of described synthetic meadow face tendency in tennis court in sports building department, and in the football field or the Rugby field, then preferred thick turf.
The present invention is in this represented specific embodiment (representing by way of example); substrate 1 top; being dispersed in thus between the fibrous formation thing 2 is particulate or granular material, as packing material or filler 3 (term used herein " particulate " and " particle " are synonyms).The function of material 3 is to make fibrous formation thing 2 remain on vertical position substantially substantially, prevents that promptly it from lodging in substrate 1 in undesirable mode.
It is emphasized that again the present invention also can be used for not using the synthetic meadow face of granular material 3.As a result, synthesizing the meadow face only is made of substrate 1 and the fibrous thing 2 that forms basically.
If granular material 3 is arranged, it is dispersed between the fibrous formation thing 2 with enough quantity so, makes the whole straight line portion of fibrous formation thing 2 dense structures can both obtain the support of filler 3.
Preferably, particles filled material 3 is homogeneous material basically, is dispersed between the top and fibrous formation thing 2 of substrate 1 in basic mode uniformly, and does not cause the layer of the stack with obvious different qualities.
In the preferred embodiment of the invention, aforesaid granular material is the granular material of granularity less than 5mm, and usually between 0.5-4.5mm, more preferably between 0.5-3mm, density is 0.9-1.6g/cm usually
3
On the other hand, according to EP-A-1 158 099 disclosed standards, the material of filler layer is polyolefine material preferably, and as polyethylene, more preferably callable polyolefine material is as callable polyethylene.
Differently be, previous materials can be made up of ethene polymers, more preferably callable ethene polymers.
The selection of filler material 3 and the form of distribution (thickness of filler layer 3 or the degree of depth, the granularity of material etc.) have determined the rigid/flexible characteristic of turf substantially.Ground as other types, especially be used as the ground of motion purposes, rigid/the flexible characteristic of aforementioned synthetic meadow face can by quantitatively accurately method discern, this method is by means of the elastic impact experiment that forms DIN standard 18035/6 test subject, and described standard and DIN standard 18032/2 define parameter or the coefficient of representing with KA (KA is the abbreviation of German Kraftabbau) jointly.
COEFFICIENT K A represents with the form of percentage, and it is to be compared and obtained by the behavioral trait of the common flat crust of being made by cement that bears ground behavioral trait that standard-sized weight falls and the identical whereabouts of load-bearing.
Under any circumstance, make and synthesize grass structure synthetic grass structure as shown in the drawing that the specific criteria with a given COEFFICIENT K A value does not constitute the particular topic of present patent application.Therefore, do not provide the detailed description of described standard here.
Diagram among Fig. 2 has been illustrated the method for the synthetic meadow face that is used for preparing Fig. 1 type.
The starting point of this method is by sheet substrate 1 expression, and this substrate has a plurality of fibrous formation things from the extended linearly shape of substrate and is used for simulating natural sod.
Need should be mentioned that at this parent material 1 and 2 is known, and on market, can buy.Mode only to exemplify, these materials may be sold with following trade name: Mondoturf (manufacturing of Mondo company); Astro Turf, Astro Play and Astro Grass (manufacturing of Astroturf company); FieldTurf (manufacturing of Field Turf company); Megagrass, Monotex, Monoslide, Terragreen (manufacturing of Polytan company); Prestige (manufacturing of Tarkett Sommer Sports Systems company); And DD Soccer Grass (manufacturing of Desso Dlw Sports Systems company).
Do as a whole, the Machinery Design of a known models of reference number 5 expressions is used for scattering on the parent material of 1 and 2 expressions and laying a certain amount of packing material or filler 3 (known models), and this packing material or filler 3 are made up of the homogeneous plastic material of for example a certain amount of aforementioned type.Aforesaid packing material or filler are dispersed in the fibrous formation thing 2, make fibrous formation thing 2 keep a basic vertical state.
With regard to laying and " distribution " granular material 3, need to consider various factors:
The first, to have mentioned repeatedly at this, technical scheme of the present invention also can be used for not having the synthetic turf of packing material 3.
Second, can implement according to the technical scheme that adopt present this area, ground on the scene, when base material 1 and 2 is laid on time ground (representing with G) in Fig. 1 after, just after being layed in the installed position of synthetic meadow face, implements described base material 1 and 2 distribution or the distribution of aforesaid granular material again.In this case, provide the device 5 general structures that adopt a kind of variable allocation unit of parent material 1 and 2, be used on base material 1 and 2, carrying out gradually the distribution of granular material.
An also have further unit relevant with allocation units 5 (indicates in the drawings, but a known type), basically be built into a rake or similar utensil, the function of this structure is to do relative motion before the allocation units 5 on base material 1 and 2, make base material 1 and 2 can be predisposed to optimum condition and be used for receiving granular material 3, this set is to make at that time fibrous formation thing 2 in fact linearly be adjusted to vertical direction, thereby rectangular with the extended surface of base material 1.
Yet, the operation of " distribution " granular material 3 can with the crimped fibre shape form thing together with a kind of in industrial environment particularly advantageous mode carry out, can describe in detail below., promptly under the condition of wall scroll production line,, obtain a kind of final material that contains aforementioned substrates material and particles filled thing 3 from base material 1 and 2.The said goods is preserved and is sent to the material forms of sheet and/or scroll needs the place of laying, and lays this product between being chiefly directed on time ground when mounted, and does not need ground on the scene to scatter.
As having mentioned the front, determine that the standard of selecting the standard of base material 1 and 2 and carrying out dispersed particulates material 3 (comprising the feature of selecting described material) is known technical scheme, so do not constitute the application's particular topic.
After the operation of finishing dispersed particulates material 3, and after the structure that a kind of main and EP-A-1 158 099 disclosed structurally associateds are provided, according to an important characteristic of the present invention, the distal portions 2b of fibrous formation thing 2 is curled or the operation of " texture ".The purpose of this step is to give fibrous formation thing 2 tree sample outward appearance as shown in Figure 1.
The present invention at present preferred embodiment in, can obtain aforesaid result by the gaseous material stream of using a kind of heat.Described gaseous material can be a kind of thermal current that is produced by pump element 6 simply, and this pump element 6 is mainly linked by a blast fan and a thermal source and forms.Usually it can be an industrial blast fan-heater, perhaps may be the rifle shape firing equipment of repacking and the thermal source that obtains, and air blast-spray gun that the workman of splash guard uses for example is installed.
As the aforementioned, in order to make described distal portions, preferably the distal portions of being made up of thermoplastic material such as polyolefine material takes place to curl, and the guiding thermal current is to the operation of the far-end 2b of fibrous formation thing 2 even can lay synthetic meadow face to implement afterwards.Generally after dispersed particulates material 3 (if use), just implement this step.
Aforesaid polyolefine material can be selected from the existing material category that is used to prepare synthetic grass structure.For example, can be that polyethylene is (according to density, the softening temperature that has is at 70-100 ℃), polypropylene (according to density, the softening temperature that has is at 130-160 ℃), or copolymer of different nature (softening temperature that has is generally in the limit range of above-mentioned definition).
In addition, it will be appreciated that,, on the production line in factory after the dispersed particulates material 3, carry out heating operation usually and prove favourable owing to multiple reason.
Especially under the selection of considering strict tolerance conditions and keeping, above-mentionedly can be applicable to regulate parameter, the flow velocity of temperature and gaseous matter for example, element 6 and the distance between the synthetic grass structure of handling of being subjected to curling.In fact, (their length, especially consider to stretch out the length of above-mentioned filler 3 parts according to the feature of fibrous formation thing 2, form the material of fibrous formation thing and the yardstick of fibrous formation thing), noted earlier is the parameter of determining to give fibrous formation thing 2 distal portions 2b amount of crimp.
The selection of thermal source, blast fan-heater or similar devices all constitutes a kind of possible selection of describing the result in order to reach in the use.
The preferred at present blast fan-heater that uses.In fact, have reason to believe that curlingly there is favourable effect in the air turbulence that causes for what help fibrous formation thing on synthetic grass structure.As an alternative, it is also conceivable that use static thermal source, for example infrared lamp or other radiant heat source.
When blast fan-heater is used as thermal source 6, and other parameter all is identical (yardstick of fiber formation thing, composition material, the temperature of gaseous matter stream, or the like), the amount of crimp that fibrous formation thing 2 far-end 2b produce depends on the charging rate of the Web materials of processing with respect to thermal source 6.
By regulating above-mentioned parameter (certainly, regulating aforesaid other parameter together), just might very accurately regulate curling degree.
This contact has been arranged, just different selections can have been arranged according to the needs of using.
For example, when being used for the tennis court, the curling of a kind of suitable high level of general preferred employing is so that produce a crimped fibre that quite closely twines at the synthetic turf top surface.
In other application, for example football field or Rugby field, the curling of general preferred less degree.
The present test specification that carries out of the application, because the heat treatment meeting forms fusing between adjacent fibrous formation thing, it is favourable heat treatment not being advanced to the point that obtains adhesion.
On the contrary, if in application, wish to obtain to have quite fine and close turf top surface, heat treatment is extended so that the point that makes adjacent fibrous formation thing have edge connection at least is favourable so.
Do not wish to be subject to any specific theory, the applicant have reason to believe the wear-resistant character of the excellence that the synthetic meadow of the present invention face is shown be because: the far-end 2b of fibrous formation thing 2 is not the very vertical direction of employing, but presenting whole calm state, the partial-length at synthetic meadow face bearing of trend is calm at least.
Mean more than that the load that sole applies does not cause very strong shearing force, but think compression and/or the bending force characteristic that has produced the crimp end of twining.
When the embodiment of synthetic meadow face has adopted filler, when in case particles filled thing 3 is interspersed among in the fibrous formation thing 2 with curling far-end 2b, filler just is limited between the winding crimp end 2b of sheet substrate 1 and fibrous formation thing 2, and this provides the relevant important technology feature of whole dense form that produces with the fibrous formation thing 2 with curling far-end 2b.
In present embodiment preferred, when carrying out the operation of above-mentioned distribution and crimped fibre formation thing in factory, The above results has conclusive importance, but when the top of carrying out dispersed particulates material 3 and crimped fibre formation thing 2 on the spot, when promptly carrying out after laying synthetic meadow face, The above results is favourable.
Because granular material 3 is limited in the sheet substrate 1, in factory, carry out crimp operation (among Fig. 2 shown in 6) and do not have the risk that granular material 3 is separated from product, therefore obtained the product that dispatches from the factory.
When following situation, above-mentioned the possibility of result can be more obvious: granular material presents slight at least bonding in some aspects, for example by adding adhesive, perhaps makes granular material 3 be subjected to certain compression when scattering and handles.
By Fig. 2 complete synthetic turf that curled product composition that workplace 6 comes out, it can be sheet or strip, is wound into the scroll thing shown in Fig. 2 label 7.
The scroll material that is obtained can be saved, and is transported to the place that needs laying.
In order to lay synthetic meadow face, only need be opened described synthetic meadow face, are routed on the inferior ground that pre-sets with this purpose to get final product, and need not the operation that filler 3 or crimped fibre shape formation thing 2 far-end 2b are scattered in ground on the scene.With above-mentioned relevant be the advantage of obtainable material, this material has after factory prepares fully accurately and reliable given feature.
Certainly, under to the prerequisite of principle of the present invention without any prejudice, the details of embodiment of the present invention and enforcement can have a great difference with as herein described, and this does not depart from protection scope of the present invention.
