Abstract

The invention discloses an anti-cracking ABS material and a preparation method of a product thereof. The method comprises the following steps: firstly, carrying out emulsion polymerization on butadiene to obtain polybutadiene latex, then carrying out graft polymerization on the polybutadiene latex, styrene and acrylonitrile to obtain a rubber graft copolymer, and finally, carrying out mechanical blending and melt granulation on the rubber graft copolymer, SAN resin and an antioxidant to obtain the ABS resin. According to the ABS material prepared by the method disclosed by the invention, the particle size of the polybutadiene latex can reach 500 nm or above, so that the ABS material is high in toughness, the impact strength reaches 350 J/m or above, and the low-temperature resistance is enhanced. A product prepared from the ABS resin is subjected to annealing treatment, so that the crack resistance of the product is further improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of anti-cracking resin materials, and in particular relates to a preparation method of an anti-cracking ABS material and its products. Background technique [0002] ABS resin is a terpolymer of acrylonitrile, butadiene and styrene, and is widely used in many industries such as medical products, automobiles, electronic and electrical equipment, instrumentation, textiles and construction. ABS resin is light yellow granular or powder opaque resin, non-toxic, odorless, relative density 1.04-1.08, has excellent impact resistance and low temperature resistance; the embrittlement temperature of ABS resin is -7 ℃, and the heat distortion temperature is 95 -120°C; ABS resin has good chemical resistance, is hardly affected by dilute acids, dilute alkalis and salts, is insoluble in most alcohols such as ethanol, and will swell when it is in contact with hydrocarbon solvents for a long time; ABS resin und...
