Problems solved by technology

However, these additives have a great impact on the mechanical properties of ABS alloy materials, especially the impact, especially PC is sensitive to metal objects and will cause serious degradation, so it is not suitable for PC / ABS system
Physical adsorption can improve odor. For example, the micropores in activated carbon can absorb odorous molecules emitted from polymer materials. However, the reason for the black color of activated carbon itself is that it can only be used in black materials.
[0005] The usual PC / ABS reinforcement materials are added with glass fiber or talcum powder, these materials do not have a porous structure and cannot improve the odor of the material

Abstract

The invention relates to a low-odor PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) reinforced alloy material and a preparation method thereof. The PC / ABS alloy material comprises the following components in parts by weight: 30-70 parts of PC resin, 20-50 parts of ABS resin, 5-15 parts of kieselguhr, 0.1-1 part of antioxidant and 0.1-1 part of lubricant. The preparation method of the alloy comprises the following steps: (a) mixing the PC resin, ABS resin, kieselguhr, antioxidant and lubricant in a stirrer; and (b) blending and granulating the mixture obtained in the step (a) with a double screw extruder to obtain the low-odor PC / ABS reinforced alloy material. The method provided by the invention is simple and easy to implement; and the kieselguhr has the characteristics of wide sources, low price, great specific area and porous structure, has the action of reinforcement of a filling material, and lowers the odor of the PC / ABS alloy since the porous structure adsorbs the micromolecules in the resin.

Description

technical field [0001] The invention belongs to the fields of polymer blending and polymer molding processing, and in particular relates to a low-odor PC / ABS reinforced alloy material and a preparation method thereof. Background technique [0002] PC / ABS alloy material takes into account the advantages of both PC and ABS, has excellent mechanical properties and processing properties, and has a wide range of applications in the fields of automobiles, electronics, communications, and chemicals, especially in recent years. Under the trend of lightweighting automobiles and replacing steel with plastics, the usage of PC / ABS alloy materials in the automotive field has risen rapidly. [0003] Although PC / ABS has a wide range of applications, it also emits an unpleasant odor under certain conditions, especially in a closed environment under high temperature conditions. In response to the requirements of automotive environmental protection and safety performance, it is more and more...
