Low-temperature-resistant flame-retarding ABS material and preparation method thereof

Abstract

The invention provides a low-temperature-resistant flame-retarding ABS material, which is composed of, by mass percentage concentration, 35-45% of 1# ABS resin, 35-45% of 2# ABS resin, 8-10% of a flame retardant, 3-5% of a flame retardant synergist, 3-5% of a cold-resistant flexibilizer, and 0.1-1% of a processing aid. The invention also provides a preparation method of the low-temperature-resistant flame-retarding ABS material, wherein the method includes the steps of: uniformly mixing the raw materials and performing extrusion granulation in a double screw extrusion machine, water-cooling the granulated material, cutting the material into granules and drying the granules to prepare the ABS material. The ABS material has high impact resistant and impact resistant at 40-50 DEG C, has very low influence on other mechanical performances and has excellent comprehensive performances.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a flame retardant ABS material, in particular to a low temperature resistant flame retardant ABS material and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer is a terpolymer composed of acrylonitrile, butadiene and styrene, referred to as ABS, and is a thermoplastic engineering plastic with a wide range of uses. . In the ABS consumption structure, there are mainly household appliances, mechanical parts, office supplies and appliances, etc. ABS resin is currently the largest and most widely used general-purpose engineering plastic in China. However, the ABS oxygen index is only 18.3-20 (<21), which is a flammable material. When a fire occurs, it will not only cause serious property losses, but also pose a great threat to human life safety and the living environment. Therefore, some electronic and electrical accessories The s...
