The special environment-friendly PU plate is characterized in that the special environment-friendly PU plate is made from the following raw materials in parts by weight: 100 parts of mixture of polyether glycol and polyester polyol, 1 to 3 parts of mixed silicone oil, 0.1 to 0.5 part of reaction type catalyst and 2 to 5 parts foaming agent; all raw materials are mixed uniformly for making a materia A l; the material A reacts with 140 to 160 parts by weight of a modified material B to generate a large foam block; the PU plate is obtained after the large foam block is cut into pieces; the PU plate is used as the raw material for producing the car roof, and has excellent environmental performance, and has the advantages of good toughness and high dimensional stability during forming.
Description
Technical field:
The present invention relates to the polyurethane foam technical field, is a kind of roof of the vehicle special environment friendly PU plate specifically, is applicable to the internal decoration of car ceiling that the feature of environmental protection is had relatively high expectations.
Background technology:
As everyone knows, in-car air quality not only endangers the healthy of human consumer, also affects the directly perceived evaluation of test ride personnel (being mainly the human consumer) to new car, therefore, each automotive OEM is all attached great importance to automotive interior material, and has formulated strict automotive interior material distribution performance testing standard.
Along with people are more and more higher to the requirement of the feature of environmental protection, the automobile industry a series of policy that also released one after another, low VOC has become the direction that the auto-parts business makes great efforts.Mainly comprise the materials such as benzene, toluene, ethylbenzene, dimethylbenzene, vinylbenzene, formaldehyde, acetaldehyde, propenal in the VOC test item.A lot of producers are the content that the method by the PU foam being carried out to aftertreatment reduces above-mentioned small-molecule substance in the PU cystose, and this method wastes time and energy and DeGrain.Accomplish that by the content that reduces objectionable impurities in chemical raw material the standard of low VOC is just becoming a popular research topic of urethane industry.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of roof of the vehicle special environment friendly PU plate is provided, mainly solve the higher problem of existing polyurethane foam board harmful substance contents.
Technical scheme of the present invention is: a kind of environment-friendly type PU plate of roof of the vehicle special use, its special character is that it is made by the raw material of following weight proportioning, 100 parts, the mixture of polyether glycol and polyester polyol, mix silicone oil 1-3 part, response type catalyzer 0.1-0.5 part, whipping agent 2-5 part, modification B material 140-160 part.
Further, described a kind of roof of the vehicle special environment friendly PU plate, its special character is that it is made by the raw material of following weight proportioning, 100 parts, the mixture of polyether glycol and polyester polyol, mixes 2 parts of silicone oil, 0.3 part of response type catalyzer, 3 parts of whipping agents, 155 parts, modification B material.
Further, described polyether glycol and the mixture of polyester polyol are that 2-3 kind polyether glycol and 1-2 kind polyester polyol in polyethers 450, polyethers 330N, polyethers 4701, polyethers 625, polyethers 3050, polyethers 303, phthalic anhydride polyester 3152, phthalic anhydride polyester L350 mixes.
Further, described mixing silicone oil is the mixing of silicone oil and soft bubble silicone oil of hard bubbling, and the silicone oil that hard bubbles is G780, Y10366, and soft bubble silicone oil L580, L-6860 are that 2-4 kind is wherein mixed.
Further, described response type catalyzer is the 1-2 kind combination in ZR-50, Z-130, ZF-11, LED-103.
Further, described whipping agent is water.
Further, described modification B material is that 70% thick MDI (PM-200) and 30% liquefied mdi (100-LL) mix and make modified isocyanate by weight percentage.
A kind of roof of the vehicle special environment friendly PU plate of the present invention, stablizing or improving on the basis of existing polyurethane foamed material physical properties, by adjustment, fill a prescription, the polyethers, response type catalyzer, water that uses low VOC is as the isocyanic ester of whipping agent, modification etc., contain the various objectionable impuritiess such as extremely low benzene, toluene, ethylbenzene, dimethylbenzene, vinylbenzene, formaldehyde, acetaldehyde, propenal in the polyurethane foam board that makes to produce, reach the environmental requirement of PU cystose; The polyethers of low VOC traditional polyethers of comparing contains few aldehyde material; Substitute traditional addition type catalyzer with the response type catalyzer, to the molecular chain of urethane, make the PU cystose there is no the volatilization of amine substance under hot environment catalyst reaction; Make water replace and be about to superseded fluorine class whipping agent as whipping agent, stop the destruction to ozonosphere, meet the environmental requirement of ODS; Use modified isocyanate, reduce the content of benzene class material in original isocyanic ester.
A kind of roof of the vehicle special environment friendly PU plate of the present invention, its principle is that objectionable impurities in proportioning is reduced, various small-molecule substances are reacted on the polyurethane molecular chain, by polyvalent alcohol and modification B material, react, foaming becomes urethane bulla piece, the polyurethane foam piece plastified carries out trimming, section, makes the PU plate of the environment-friendly type of internal decoration of car ceiling special use.
Compared with the prior art a kind of roof of the vehicle special environment friendly PU plate of the present invention has outstanding substantive distinguishing features and marked improvement, the physical properties of PU sheet material is more excellent, stopped the destruction to ozonosphere, the automotive interior roof that makes to produce has reached the requirement of VOC, makes the health of passenger in automobile obtain guarantee.Embodiment:
