Abstract
The invention discloses a modified PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene) engineering plastic which is composed of the following components in percentage by weight: 40-65% aromatic polycarbonate, 30-55% of acrylonitrile-butadiene-styrene terpolymer, 1-3% of compatilizer, 1-3% of impact modifier and 0-1% of lubricant. The compatilizer is a polysiloxane-acrylate compatilizer; the lubricant is TAF; and the impact modifier is a methyl methacrylate-butadiene-styrene terpolymer modifier. The PC/ABS engineering plastic disclosed by the invention has better compatibility, and the impact resistance, stretching resistance and other properties of the engineering plastic are also greatly enhanced on such basis.
Description
Technical field
The present invention relates to and belongs to technical field of polymer materials, is specifically related to a kind of modification PC/ABS engineering plastics.
Background technology
PC plastic cement be a kind of transparency up to 90% thermoplastics, not only good rigidly toughness is high for it, also has higher shock strength, the advantages such as high dimensional stability, and ABS is vinyl cyanide, divinyl and cinnamic blend or terpolymer, be a kind of tough and tensile and have the thermoplastics of rigidity.PC/ABS engineering plastics combine the excellent specific property of bi-material as the alloy of two kinds of plastics, have a wide range of applications in fields such as automobile decoration piece, household electrical appliance, electronic product casings, especially electronic product popularizing in life, also been proposed new requirement to the wear resistance being applied in this zone material.
PC, ABS in the course of the polymerization process, between different polymkeric substance, polarity and interface difference is there is between polymkeric substance and glass or other inorganic functional fillers, physical entanglement is lacked between each component, so that consistency is poor between them, the polymer alloy obtained is difficult to the respective advantage of real performance, in prior art, the consistency of PC/ABS alloy need to improve, comprehensive mechanical property also has much room for improvement, in order to improve the consistency between each component, give full play to PC, the rigidity that ABS is good separately and toughness, to improve the wear resistance of PC/ABS alloy, compatilizer, the use of the supplementary additives such as impact modifier just seems very important.
The production method industrialization of silicone acrylates class compatilizer, polysiloxane has snappiness, good water tolerance, fabulous thermostability, and polyacrylic acid ester cpds is also applied widely in coating, tackiness agent etc. with its good masking, smooth, transparent box mechanical property, the silicone acrylates be polymerized by them not only combines both advantage, also be widely used in engineering plastics as compatilizer silicone acrylates, while raising engineering plastics consistency, its mechanical property is also greatly improved.
TAF lubricant is for base-material with ethylene bis-fatty acid amides (EBS), under the effect of catalyzer, reactive monomer containing polar group and EBS react and form BAB type multipolymer, this multipolymer had both maintained the oilness of EBS, there is again the polar group that can combine with glass, inorganic filler surface segment polarity group, more can improve the surface smoothness of matrix material.
