For many years, moulding loam is used as the material of toy and teaching aid always, an important advantage of this moulding loam is that it can be molded into various shapes, but also there are some shortcomings in it, and one of them shortcoming is that its viscosity is big, is easy to the surface of making dirty and contacting with it, another shortcoming is that its dimensional stability is relatively poor, that is to say that the object with moulding loam is made also will be out of shape even be subjected to very little pressure.Exactly, above-mentioned disadvantageous performance has hindered moulding loam and more has been widely used for plastic those purposes that ten minutes needs this material, for example in the scenery of gardens, build the scenery of outward appearance by design variation, in odeum, build all kinds of showpieces, and as the material of building scenery in the aquarium.In fact definite, the problem that runs in this class field just becomes when moulding loam contacts with water exactly and more and more is clamminess.
Therefore, an object of the present invention is to provide a kind of material that replaces moulding loam, this material at room temperature is shaped easily and makes the stable molding body of various sizes, and can easily they be broken into into pieces granular materials subsequently, directly is molded into the new in other words shape of new object then.Another object of the present invention provides the material of being made by the raw material that environment is harmless to the health in other words.A further object of the present invention provides and both can be used as the making teaching aid, again can be in large quantities as building the material with the garden architecture structure of visualization outward appearance and the sight spot structure in the aquarium and the model rail in the structure of sight spot.
Another purpose of the present invention provides the method for a kind of above-mentioned sand material mixture of manufacturing (sand material mixture that moulding is used), described sand material mixture is suitable for the substitute as moulding loam, and can be used for other purposes, for example as the material of making scenery in the aquarium and the various emulation scenery of design etc.
Above-mentioned purpose of the present invention and other purposes on the one hand by respectively in claim 1 and 14 independently the sand material mixture of regulation and the method for making such sand material realize, realize by adopting again on the other hand by the sort of sand material mixture of claim 15 regulation independently.Other relevant claims then concrete regulation most preferred embodiment of the present invention.
Generally speaking, the present invention relates to contain the sand material mixture of sand or sand shape material and binding agent, described binding agent is a kind of beeswax, a kind of material or a kind of compound that is similar to beeswax that is similar to beeswax, and it at room temperature is solid-state, but still has required viscosity.Each component of forming sand material mixture is mixed mutually, make the particle of sand or sand shape material wrap the clad of a layer binder, preferably, the sand material particle that the mixing of above-mentioned each component make to disperse is individually wrapped clad, and can not want the time spent to form little sand group significantly before compacting.
Though early being arranged, the sand of use and binding agent make casting mold and core on foundary industry, but, the sort of sand material mixture that uses in this industrial department contains the binding agent of resin, thermosetting plastics, linseed oil or similar substance and so on usually, is that casting mold or core can tolerate the high temperature in the casting process so that make manufactured goods.And those used binding agents can not be used to realize purpose of the present invention usually.In addition, from human health and sanitary viewpoint, the binding agent that is used for casting mold and core quite is not suitable for makes toy and the similar articles articles for use etc. of for example playing.
Japanese Patent Application Publication JP 57-1427142 (referring to JP publication 1982-12-04, M class, No.176 joint; Vol.6, P.55) No.246 disclosed an example of the material of making casting mold.This publication discloses a kind of casting sand that contains binding agent and be heated to above the binding agent melting temperature in use, during use, with compound pack into sandbox or core box, force then to be cooled to be lower than the temperature of binding agent fusing point, so that make casting mold and core is stable and sclerosis.As binding agent, use a kind of solid-state have down high-adhesion can material so that make casting mold/core under common treatment temperature, keep structural globality, can make the reusable characteristic of casting sand but still have.The binding agent that uses in the above-mentioned molding sand is an ethylene glycol and with the wax material of paraffin as main body.This publication only is concerned about about making the problem that casting mold and core brought, and therefore, fails to consider the problem that the scenery configuration aspects in the scenery of relevant manufacturing, teaching aid, construction model train structure and building structure or aquarium occurs.
The similar publication of speaking of the core of making casting mold has WPI/ Derwent digest No.75-58260 W, 7535 weeks, Russian Patent digest SU 456674 (Kashirate sentrolit) (on February 5th, 1976).This publication discloses a kind of material that can be used for making complicated core, and this material mainly is the compound of following ingredients: the silica flour at least about 70%, 5～10% aluminium oxide, 1.5～3% boric acid, 1～2% stearic acid and 16～20% the moulding compound of being made up of paraffin, artificial ceresin, paraffinic hot tearing residue and montan wax additive.This material is heated to 65～70 ℃ in use and is pressed into required molding body.Because above-mentioned publication relates to the manufacturing of complicated core (insert), so used stone flour, the very little granular materials of particle size just.So the moulding sand material that above-mentioned sand material mixture and the present invention propose is a fundamental difference.
WPI/ Derwent digest No.90-318835,9042 weeks, Russian Patent digest SU-1550137 (Leningrad Plakhanov Mine, 1990,3, the sand material mixture of used natural rock material when 15) disclosing a kind of tensile state that is used for replacing forming at the research rock, the binding agent in this sand material mixture also contains shellac and shale tar except beeswax.This material and moulding sand material disclosed by the invention are fundamental differences.
U.S. Pat-A-3607332 discloses a kind of thermoplasticity Modeling Material, and the performance of this material is equivalent to moulding loam, and is soft, but finger pressure distortion at room temperature.Component as this thermoplasticity compound, use a kind of plastic argillaceous material and a kind of organic plasticising carrier to mix, its new being characterised in that, this plastic argillaceous material added a kind of tiny balloon granular or the granular light-duty filler of hollow sheet crystalline form, to reduce the gross weight of compound.Above-mentioned plastic clay shape material is naturally occurring clay, for example kaolinite, imvite or bentonite.Above-mentioned material is the compound that is similar to moulding loam, and it contains a large amount of very thin granular materials.
U.S. Pat-A-5374384 disclose a kind of improved, be the moulding loam of base with fine-powdered mica grain and carbon black, but the tabular in other words wax material of the sheet as thin as a wafer that it gets up with cold coiling a kind of softness, semi-solid is as binding agent, and this wax material has the ability of high counter-bending resistance to deformation in other words when placing between two fulcrums as beam.
U.S. Pat-A-4336071 discloses a kind of plastic moulding loam, and it contains 50～70% binding agent, 10～40% plasticizer and the aluminium hydroxide of solvent and 5～40%, also adds pigment and other fillers below 10% sometimes.This patent description this air dried self hardening in other words and compound that can permanent moulding, the quality of this compound that can permanent moulding is suitable with the quality of moulding loam.
The compound of the simulation moulding loam of making according to the prescription of above-mentioned US-A-3607332, US-A-5374384 and US-A-4336071, its performance can not be equal to the sand material mixture of mouldable of the present invention.
According to the present invention, granular material in sand material mixture sand in other words can be the rock material (for example marble powder) of natural sand, pulverizing, but also can be (though being not equal to preferably) granular polymer material or other granular material, especially when scenery structure that sand material mixture will be used to make for example emulation, more can use the latter.Also can adopt for example microspherolitic sand shape of lightweight sand material as sand shape material, certainly can also be with the compound of various types of granular materials.The particle size range of granular material is (better to about 2.0mm, preferably to about 1mm) from about 0.02mm (preferably from about 0.063mm) to about 3.0mm.Preferably, the mean particle size range of granular material is about 0.08 (or 0.1 or 0.15) mm～about 0.6 (or 0.5) mm.
According to the present invention, the binding agent in the sand material mixture should be beeswax, be similar to the material of beeswax or be similar to the compound of beeswax or the compound of this class material.
The suitable binding agent of the above-mentioned type also has the mixture of beeswax substitute ceresin or ceresine and paraffin or microcrystalline wax except natural beeswax.For example, the CEREWAX 2T that can buy from Sweden Sveda AB company is the ceresin material that is suitable for, and German H.B, the LUNAFLEX of Fuller GmbH company supply
4919 is a kind of suitable microwax (a kind of plasticity hydrocarbon wax of the side chain micro-crystal type by the supply of German H.B.Fuller GmbH company).
The beeswax of natural beeswax or the purifying of handling can be used as beeswax.For example, the Bivax M.S of Sweden Biredskapsfabriken AB company supply is the natural beeswax that is suitable for, and the Bivax Vit No.1 (B 1015) of the bleaching beeswax of Sweden Joel Svenssons Vaxfabrik AB company supply and the supply of Sweden MB-Sveda AB company is processing and beeswax purifying that is suitable for, and the another kind of available material that is similar to beeswax is LUNACERA
M (by the supply of German H.B.Fuller GmbH company), this material is a kind of microwax with ceresine structure, and is the very balanced linear hydrocarbon wax and the mixture of side chain hydrocarbon wax.
LUNAFLEX
4919 (a kind of hydrocarbon waxs with mouldable of side chain microstructure, the supply of Germany H.B.Fuller GmbH company) with paraffin 52-54 (52～54 ℃ of its fusing point, contain≤0.5% oil, promptly by the RA007 paraffin of Sweden MB-Sveda AB company supply) mixture be an example of the available compound that is similar to beeswax.
In order to realize purpose of the present invention, the important point is that binding agent should have the viscosity that roughly is equivalent to beeswax or common beeswax substitute.If the solvent of binding agent lacks above-mentioned performance, just add modifier diluent in other words possibly.Can use fine material (particle mean size is less than 0.01mm) as diluent, this fine material only adds after binding agent and sand material mix.Adding the benefit that diluent brings after this is, occur can not stoping in the time of fine material hindering the even distribution of binding agent in other words at sand grain surface, above-mentioned fine material has big surface area, therefore need to replenish relatively large binding agent, but all components mix so that reach same coating degree.
When for example making model trajectory scenery in the aquarium or scenery building structure of sand material mixture and need improve its structural integrity, also can add the suitable fibre reinforced materials of performance than the short glass fibre shape.
If mixing mutually, the viscosity deficiency of binding agent, the less beeswax material of beeswax shape material that then can viscosity is bigger and another kind of viscosity remedy above-mentioned deficiency.Also can add the material that some increase viscosity, for example a spot of paraffin oil.Isopropyl palmitic acid, isopropyl myristate or tall oil.But, when adding the material of above-mentioned increase viscosity, to guarantee that importantly the ratio of its addition is low as best one can, in case hybrid adhesive ooze out oily mater cling finger or be bonded at material surface that it contacts on.
If want to make the sand material to have special color, certainly select the sand material that has required color for use, still, also can and also preferably the sand material with before binding agent mixes earlier to its dyeing.See through the adhesive layer that beeswax or similar beeswax shape material form if want to avoid the pigment gamut, the dyeing of sand material can be undertaken by pigment paste, and described pigment paste contains and is dispersed in fusing point than as high polymer of the beeswax of the binding agent in the sand material mixture or beeswax shape material or the pigment in the wax material.The addition of pigment depends on the colouring intensity and the shade that will obtain.Proved already that adding the amount of pigment that accounts for sand material weight 0.01～1.0% (wt) was effectively, is preferably adding 0.05～0.5% (wt).The pigment paste that the example that has been proved to be suitable and available color pigment dispersion has German Bayer AG company to make, these pigment pastes on market with LEVANYL
LR (a kind of organic type fine powder pigment paste) and LEVANOX
The trade name of (a kind of inorganic type fine powder pigment paste) is sold.In order to improve clad/wettability, can adopt the emulsifying agent Ks, OS and the WNS that sell by above-mentioned company.
In order to alleviate the gamut of pigment, above-mentioned pigment paste can be mixed mutually with condensate or wax dispenser.The POLIGEN that the example of this dispersion has German BASF AB company's manufacturing and sells
PE dispersion and POLIGEN
RW dispersion and German Hoechst AG company's manufacturing and the HORDAMEP that sells
PE 34 NEU dispersion and LICOMER
The W11 dispersion.When the sand material being dyeed, the mixture of the dispersion of pigment paste and mentioned kind can be added in the sand material, and carry out mixture operation continuously up to pigment paste and dispersion and the abundant fusion of sand material with above-mentioned dispersion.After the drying, said mixture forms a color layers on sand grains, and color pigment is sealed in used polymer or the wax material dispersion in principle.Subsequently that the sand material of this dyeing and final sand material mixture is used binding agent is that beeswax, the material that is similar to beeswax or the compound that is similar to beeswax mix mutually.
Sand material mixture of the present invention has many purposes, for example, is used to make toy, teaching aid, gardens scenery, and the scenery structure in construction odeum or the aquarium.Because this material can form a kind of liquid-tight material under its compaction state, so it also can be used for forming the liquid-tight seal layer of the densification in bird bath and the pond.
Illustrate in greater detail the present invention referring to accompanying drawing below.
Fig. 1 simply illustrates the enlarged drawing in the cross section of the molding body made from sand material mixture of the present invention, for the purpose of more clear, the size relationship of each component is exaggerative to some extent (adhesive surface clad and micropelletoid wall thickness in fact than shown in the figure thin) among the figure.
According to the present invention, the surface coverage last layer of the sand material particle 10,11 of many dispersions is similar to the thin layer 12 of beeswax material, according to illustrated embodiment, use two types sand material particle, be a kind of be sand grains 10 (for example quartz sand), a kind of is roughly identical with sand grains 10 framboid 11 of particle size distribution.The adhesive attraction of particle is a binding type in the molding body that sand material mixture is made, and its adhesion strength depends on the cohesive force and the adhesive aggregation performance of beeswax shape material.As shown in drawings, because dispersed particles respectively has the independently surface coating layer of wax-like materials, so between discrete particles, there is external hole 13, this feature performance of beeswax shape surface coating layer in addition presents sand material mixture to be similar to the situation of Mare Humorum sand, but thereby make compacting of sand material and moulding, but and sculpture precedent such as chiltern building.And, if with mechanical means with above-mentioned molding body in other words sculpture break into pieces, sand material mixture also still keeps above-mentioned character.Therefore, sand material mixture can be used to make new molding body and similar object repeatedly.

Adopt identical hybrid technique in the example 39 and 41, its difference is, the sand material of heating be used for the melt paraffin that disperses sand grains coating one deck fusion wax material mixed after only add the rock powder, in the process of adding this rock powder, stir continuously, and continue to stir till the temperature of sand material mixture drops to below 30 ℃ in the reinforced back that finishes.Then this sand material mixture being transferred to another can make it to be cooled in the container of room temperature.
The density about the compound of sand material and sand material and binding agent described in the following example is measured respectively in the following manner:
With the measuring vessel of a kind of known volume and weight, when measuring the bulk density of sand material, container is filled the sand material, and vibration gently, with one ruler unnecessary sand material is scraped off then.When the density of the compound of measuring sand material and binding agent, fill sand material mixture with same measuring vessel, and use the thumb compacting, also unnecessary compacting sand material mixture is scraped off with one ruler.Weight of weighing measuring vessel and the sand material of adorning all in the above two kinds of cases.Deduct the weight of measuring vessel then from the weight that is measured.(density is 1.0g/cm to calculate the container weight of adorning the sand material and the water that is equivalent to the volume of measuring vessel then
3) the merchant of weight, be bulk density.
Use following sand material, rock powder and binding agent at example 16～49:

Can find out from example 24～38, can contain lightweight microspheric mineral grain in the sand material, so just can change the density and the weight of sand material.Density is lower than 1.0g/cm
3The sand material products be suitable for being molded into briquet or other shapes that can float on the surface.
Can find out that from example 16～19 amount that increases paraffin oil can make the gained sand material mixture obtain structure softer and that viscosity is bigger, though this sand material mixture easily sticking hand when moulding, the amount that increases paraffin oil can be improved water resistance.
Can find out that from comparative example 47～49 performance that all impairs the gained sand material mixture is seen in sneaking into of fine powder material (" rock powder ") from every side, no matter the rock powder is before the interpolation wax material or is mixed in the sand material after adding wax material all to be like this.
Example 34～38 shows that sand shape material can contain the light material that is higher than 50% (wt).In order to obtain a good result, the amount of binding agent should be controlled at the upper limit of scope, preferably is 6～10% of sand material mixture weight.
