Abstract

The invention discloses a method for preparing an acrylonitrile-butadiene-styrene copolymer for an instrument panel. The method comprises mixing a zeolite powder compound, potassium titanate whiskers,heavy calcium carbonate, nano-talcum powder, an ethylene-propylene-diene monomer, sodium lauryl sulfate and oxidized polyethylene wax, carrying out heating along with stirring to obtain a pre-mixtureb, mixing an acrylonitrile-butadiene-styrene copolymer and polyvinyl chloride, carrying out heating along with stirring, adding the pre-mixture b, tert-butyl hydroperoxide, 1, 1-bis(tert-butylperoxy)cyclohexane and a silane coupling agent Si69 into the mixture, carrying out heating along with stirring to obtain melt, and carrying out extrusion and grain-sized dicing to obtain the acrylonitrile-butadiene-styrene copolymer for an instrument panel. A preparation method of the zeolite powder compound comprises crushing zeolite powder, adding rosin-modified phenolic resin into the zeolite powder,carrying out heating stirring, adding epoxidized soybean oil-modified phenol resin into the mixture and carrying out heating stirring to obtain the zeolite powder compound.

Description

Technical field [0001] The invention relates to the technical field of automobile instrument panels, in particular to a method for preparing an acrylonitrile-butadiene-styrene copolymer for instrument panels. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS resin) has the characteristics of easy molding and processing, dimensional stability, good stress crack resistance, and high heat resistance strength, so it has become the most produced plastic in recent years One of the alloy varieties is widely used in the field of instrument panels. [0003] However, the currently prepared ABS resins have low impact strength, generally less than 800J / m, which cannot meet the requirements of some applications requiring high impact strength. Summary of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes a method for preparing an acrylonitrile-butadiene-styrene copolymer for instrument panels, wh...
