Description
Technical field
The utility model relates to the PVC plastic irregular profile, relates in particular to a kind of weather-proof color PVC plastic irregular profile.
Background technique
The PVC plastic irregular profile is developed to today, has been a very ripe product: product comprises outdoor goods such as PVC plastic door and windows profile, PVC exterior wall cladding, PVC synthetic resin watt, PVC guardrail.Along with the increase day by day of people's individual demand, PVC plastic irregular profile colorize is subjected to people's favor gradually.PVC plastic irregular profile colorize is developed to today, goes through various ways.Colored PVC plastic irregular profile comprises: entire body look profile shapes, imitative wood grain profile shapes, overlay film profile shapes, fluorocarbon-sprayed profile shapes, colored PMMA co-extrusion profile shapes, colored ASA co-extrusion profile shapes, imitative wood grain ASA co-extrusion profile shapes etc.
At first, entire body look profile shapes, imitative wood grain profile shapes enter into people's sight, are once accepted by people.But as time passes, the defective of the two weatherability difference progressively embodies, the color fastness that mainly shows as product is poor: when it is subjected to solar radiation, it is aging that color pigment is taken place by influence of ultraviolet light easily, through the thin out (chromatic colour particularly of color will take place after a while, as redness), significant change such as wood grain disappearance, influence visual appearance greatly.In addition, As time goes on PVC itself also can take place to wear out its colour changed into yellow.This phenomenon is under the long-time irradiation of daylight (mainly being the influence of ultraviolet), and it is particularly evident to become.
In order to address this problem, overlay film section bar, spraying section bar, PMMA co-extrusion section bar, ASA co-extrusion section bar, imitative wood grain ASA co-extrusion section bar etc. have been developed in succession.They are subjected to a sun-exposed side to increase the special substance protective layer that one deck has weather-proof function by technology such as overlay film, spraying, co-extrusions at the PVC plastic irregular profile, and simultaneously, protective layer has gay colours.Specific as follows:
Overlay film profile shapes: be profile shapes surface, paste the film about one deck 0.2mm once more in moulding.This film has splendid weatherability, and film can be made various colors and decorative pattern simultaneously, and because the special construction of film material itself makes it have splendid weatherability and color hold facility.The structure of film is a kind of double layer construction, and the top layer is the good PMMA resin of a kind of transparency (polymethylmethacrylate is commonly called as plexiglass, acrylic), and bottom is painted flexible PVC material.PMMA has splendid weatherability, is extraordinary a kind of in the known resin.According to the specific reason of Lang Mudun, when daylight whenever saw through the PMMA layer of 0.005mm, ultraviolet ray intensity can decay 50%, and when the PMMA layer thickness reached 0.05mm, the ultraviolet in the daylight can be attenuated 99%, so can not produce considerable influence to the painted flexible PVC layer in bottom.(annotate: German Reynolds Li Te does the best producer of this film at present in the world, and its Related product accounts for global 90% market share.The PMMA layer of the beautiful special film of Reynolds is 0.05mm, and the said firm all did weather-proof test to all colors of producing, reaches colour section bar weatherability index fully).
Spraying profile shapes: be profile shapes surface, spray one deck fluorocarbon material as thin as a wafer once more in moulding.As everyone knows, the weatherability of fluorocarbon material is very good.Treated fluorocarbon material can be produced multicolour and texture.
Colored ASA (PMMA) co-extrusion profile shapes then adopts one-shaping technique, in the profile shapes extrusion process, and direct colored ASA (PMMA) about surperficial co-extrusion one deck 0.2mm.Facts have proved that this material is the color hold facility preferably, be better than the color hold facility of PVC greatly.On monochromatic ASA basis, imitative wood grain ASA co-extrusion section bar is obtaining exploitation.The mechanism of imitative wood grain ASA is: ASA wood grain co-extrusion material is mixed by two or more plasticizing rates, mobile different material, wherein the colored ASA as major ingredient plays the effect that primary colours are provided, consumption accounts for the overwhelming majority, and the less another kind of color ASA material of consumption plays the effect that wood grain is provided; Both plastify in the co-extrusion machine, in theory, because (the colored ASA material plasticizing rate that general consumption is few is slow for both plasticizing rates, difference of flowability, flowability is also weaker), can cause a kind of inhomogeneous dispersion of material, form the colored ASA thin layer that one deck has wood grain effect at product surface.
Imitative wood grain technology: be exactly that different plasticizing rates of having of two or more and mobile material mix by a certain percentage, the raw material that is commonly used to generate wood grain effect all exists with granular, its plasticizing rate and mobile want relative mistake some.After mixture enters the extruder plasticizing, under suitable process conditions, on product, form irregular decorative pattern, transfer, will give strong woodiness touch with suitable color.At present, this technology realizes than being easier on the PVC material.
Co-extrusion technology: be to use the extruder more than two or two, extrude two or more material respectively; The material of plasticizing is merged by the mould of a particular design, finally forms product.
The defective and the deficiency of aspects such as the structure that existing background technique exists, function:
1, film coating technique belongs to the post forming technology, promptly pastes one deck Weather-proof film at product surface after the finished product moulding, and is middle through dispelling process operations such as impurity, gluing; And overlay film is merely able on more regular surface, and at the privileged sites of profile shapes, very difficult realization is pasted preferably.Therefore, have not yet to see the whole profile shapes surface product of overlay film fully, the color of product surface is inconsistent, can only accomplish the surface portion colorize.
2, imitative wood grain technology belongs to one-shaping technique, and this technology should be a mature technique in the PVC material, but on the ASA material full maturity not, particularly the plasticizing process in co-extrusion machine is to the technological requirement strictness; Situations such as obvious aberration, even wood grain effect disappearance appear in the product of different platform easily.Make it when product surface forms a weathering layer (being subjected to sun-exposed surface that coextruded layer is arranged usually) at the collocation co-extrusion technology, make profile shapes have color effect, but still be difficult to realize the color and the wood grain effect of entire body unanimity; If painted in addition on the PVC profile shapes for this reason, be difficult to accomplish that color and wood grain with the ASA material are consistent.And the ASA material aborning, is easy to generate defectives such as scuffing, and this phenomenon is having show on the material of color more obvious, and the color of abraded area can be light partially shallow partially.
Summary of the invention
In order to solve the technological deficiency that exists in the prior art, the purpose of this utility model provides a kind of Weather resistant wood-grain imitating PVC plastic profiled bar, and this PVC plastic irregular profile has the characteristics of gay colours and decorative pattern, mature production technology for a long time.
In order to realize above-mentioned technical purpose, the utility model has adopted following technological scheme:
Weather-proof color PVC plastic irregular profile, this profile shapes comprises the PVC profile shapes that entire body is painted, it is to have transparent optical effect that the outer surface of PVC profile shapes has the transparent material layer of high weathering resistance, the transparent material layer of high weathering resistance by coextru-lamination, and is fit to the material that plasticizing is extruded.
As preferably, the transparent material layer of above-mentioned high weathering resistance is PMMA or ASA.The transparent material layer of most preferred high weathering resistance is PMMA.
Above-mentioned PVC profile shapes can be designed various wood grain effects according to customer demand; For example, walnut, cherrywood, oak or the like perhaps are monochromatic section bar.As preferably, above-mentioned PVC profile shapes is the wood-grain imitating PVC profile shapes.
As preferably, the thickness of the transparent material layer of above-mentioned high weathering resistance is 0.05～0.5mm.The thickness that the transparent material layer of preferred, above-mentioned high weathering resistance is arranged again again is 0.1～0.3mm.Most preferably, the thickness of the transparent material layer of above-mentioned high weathering resistance is 0.2mm.
The utility model has following characteristics with respect to prior art:
1, utilized the mechanism of the beautiful special Weather-proof film of Reynolds, promptly the weatherable materials of co-extrusion one deck with high transparent protected the material of following weatherability difference, makes it have gay colours and decorative pattern for a long time.Compare with the overlay film profile shapes, the forming process of this invention simple (belonging to once-through) segregation phenomenon can not occur in the use, and the overlay film product just the corner warpage may occur.And this invention product has advantages such as the color of entire body unanimity and wood grain effect, compares with single face overlay film (perhaps two-sided overlay film) to have better aesthetic.
2, the ASA that will utilize co-extrusion technology to produce imitates the wood grain in the wood grain profile shapes, transfers in the PVC material to produce.Make imitative wood grain effect in ASA, its difficulty is far above making imitative wood grain effect in the PVC material, and what the latter's technology will be obviously ripe is many; And the wood grain effect in the PVC material will relatively easily be controlled aberration.
3, changed the difficult point of the color endurance difference of the imitative wood grain profile shapes of common PVC entire body.The weathering layer of co-extrusion will improve the lasting weather-proof ability of imitative wood grain effect greatly.And theoretically, color sustainability of the present invention will be higher than colored PMMA co-extrusion profile shapes and colored ASA co-extrusion profile shapes; Because colored PMMA and ASA particle are by adding pigment toner and other some auxiliary elements in PMMA or ASA, after the mixing again granulation obtain; After the plasticizing of this particle is extruded, the inevitable thin film that forms on the surface of pigment toner, this layer pigment can not obtain the complete preservation of PMMA or ASA, and therefore colored PMMA co-extrusion profile shapes and colored ASA co-extrusion profile shapes also can variable colors, and be just slow than the variable color of PVC material.
4, save this step of angle rear complementary color clearly.Existing various weather resistant colour section bar all can not be avoided a problem, i.e. need angle clearly after the profile shapes welding, and this white bed material will certainly occur.And this novel imitative wood grain profile shapes has the painted wood grain effect of entire body, still is wood grain effect behind the clear angle, therefore needn't carry out complementary color and handle.
