Description
Technical field
The present invention relates to a kind of modified plastic material and preparation method thereof, particularly relate to a kind of heat-resisting, anti-impact, the strong black acrylonitrile-butadiene-styrene (ABS) of spun glass (ABS) modified plastics and preparation method thereof.
Background technology
Spun glass strengthens acrylonitrile-butadiene-styrene (ABS) (ABS) matrix material, is to be matrix with the acrylonitrile-butadiene-styrene (ABS), is the matrix material that strongthener is processed with the spun glass, combines the performance of acrylonitrile-butadiene-styrene (ABS) and spun glass.Acrylonitrile-butadiene-styrene (ABS) is broad-spectrum thermoplastic engineering plastic, is applied to fields such as machinery, electronics, electric, instrument, household electrical appliance, military project.But its bending stretch intensity is lower, and thermotolerance is not enough, does not reach the application requiring of acrylonitrile-butadiene-styrene (ABS) aspect automobile.Spun glass strengthens vinyl cyanide-butadiene-vinyl benzene composite material and has good comprehensive performances, and intensity is high, good rigidly, good moldability, dimensional stabilizing.Simultaneously, add the heat-drawn wire that spun glass can suitably improve matrix material, increase substantially tensile property, reduce the coefficient of linear expansion and the molding shrinkage of material.But because the interpolation of spun glass, shock strength obviously descends.
Strengthen the lifting of the overall performance of vinyl cyanide-butadiene-vinyl benzene composite material for spun glass, had a large amount of research carrying out.For promoting the associativity between spun glass and the acrylonitrile-butadiene-styrene resin matrix, some patents have proposed solution.Set forth fiberglass surfacing and be through one or more blend of the vinyl toluene that contains epoxide group or vinyl cyanide and vinylbenzene, nucleocapsid structure, αJia Jibenyixi, TEB 3K and handled.Document is mainly paid close attention to processing characteristics, apparent roughness and aberration, and after so handling, apparent and aberration improves.For example; C1-12 straight-chain dicarboxylic acid tin alkyl with 0.1% to 5% (dibutyl tin maleate, maleic acid dioctyl tin) or C1-12 loop chain di-carboxylic acid organo-tin compound coupling agent; Join graft rubber and vinylbenzene, in the system of vinylbenzene/vinyl toluene/acrylonitrile copolymer.This system still demonstrates good processing characteristics, good anti-impact and resistance toheat when the spun glass that adds 20%.In the case of over-all properties the best, unnotched impact strength (a
n RT) be 22KJ/m
2, notched Izod impact strength (a
k RT) be 9.1KJ/m
2, Vicat B is 108 ℃.Some document descriptions in a kind of acrylonitrile-butadiene-styrene resin, add spun glass and a kind of silicone couplet (β-(3 that contains epoxide group; The 4-epoxy cyclohexane) ethyl trimethoxy silane; The reaction product of alicyclic epoxy and a kind of silane coupling agent), the acrylonitrile-butadiene-styrene (ABS) compound system that makes has higher draw tensile strength and resistance to impact shock.Bibliographical information is in the acrylonitrile-butadiene-styrene resin that the melt blending continuous bulk is produced; Add the compatilizer atactic styrene-maleic anhydride copolymer, processing aid and alkali free glass fibre are prepared resin system excellent in cushion effect, that flexural strength is high.Best case is that heat-drawn wire is 101.5 ℃, and (ASTM D6481.82MPa, 6.4mm), cantilever beam impact strength is 11.5KJ/m under 21.6% the condition at the spun glass addition
2Bibliographical information is changed into the composite of atactic styrene-maleic anhydride copolymer and epoxy resin with compatilizer; The best system that obtains is 30% o'clock at spun glass, has obtained having fine intensity, toughness, resistance toheat, flowing property; Warpage is not floated fine good system.
In sum, no matter be to add various coupling agents, the glass surface treatment still adds compatilizer, all is conceived to increase the bonding force of spun glass and matrix resin.Through increasing bonding force, reach the purpose of improving erosion-resisting characteristics, raising thermotolerance and improving tensile property, this means are very limited after all to the lifting of thermotolerance and erosion-resisting characteristics after all.The present invention is guaranteeing for improving its thermotolerance and erosion-resisting characteristics a suitable method of operating to be provided under processing characteristics and the apparent condition.
