Abstract

The invention relates to a preparation method of a nano particle reinforced ABS (acrylonitrile butadiene styrene) composite material and belongs to the technical field of ABS composite materials. The preparation method provided by the invention comprises the following steps of: firstly coating nano particles by utilizing a surfactant to form surface modified nano particles and then carrying out melt blending on the surface modified nano particles with ABS by utilizing a double screw extruder to obtain ABS composite material aggregates, wherein the surface modified nano particles are organic montmorillonite, nano titanium dioxide and nano hydrotalcite. When the preparation method provided by the invention is applied to modification of recycled ABS, mechanical property and ageing resistance of the recycled ABS can be obviously improved, the properties of the modified ABS can meet and even be higher than the standard requirements of plastic parts for a motorcycle and an electric vehicle, and the modified ABS can replace a new ABS material.

Description

technical field [0001] The invention relates to the technical field of ABS composite materials, more specifically, the invention relates to a nanoparticle-reinforced ABS composite material and a preparation method thereof. Background technique [0002] ABS resin is a general term for impact-resistant thermoplastic resin composed of three components: acrylonitrile, butadiene and styrene, also known as ABS polymer. ABS resin combines the advantages of the three components, in which the styrene component provides good processing performance, the acrylonitrile component contributes to the strength and chemical resistance of the resin, and the butadiene component brings the resin Good impact performance. Because ABS resin has the advantages of good impact, processability, dimensional stability, wear resistance and chemical corrosion resistance, it can be used in the environment of -40-100 ° C. Therefore, ABS resin has been widely used in recent years. Automobiles, home applianc...
