Abstract

The invention relates to a flame-retardant acrylonitrile-butadiene-styrene resin composition, which comprises the following components in part by weight: 100 parts of acrylonitrile-butadiene-styrene resin, 0.5 to 15 parts of toughening agent, 14 to 30 parts of flame retardant and flame retardant synergist, 0.1 to 0.5 part of antifogging agent and 0.1 to 2 parts of antioxidant and lubricating agent. The flame retardant is added into the flame-retardant acrylonitrile-butadiene-styrene resin composition, the composition has excellent flame retardancy; in the formula, the components have better compatibility; meanwhile, due to the synergism of the lubricating agent and the antioxidant, the processing fluidity of the flame-retardant acrylonitrile-butadiene-styrene resin composition can be improved and the dispersion performance of the flame retardant in the composition can be improved; and the prepared flame-retardant acrylonitrile-butadiene-styrene resin composition has high impact strength, bending strength, tensile strength, flame retardancy and fluidity. In addition, the invention also relates to a method for preparing the flame-retardant acrylonitrile-butadiene-styrene resin composition.

Description

【Technical field】 [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant acrylonitrile-styrene-butadiene resin composition and a preparation method thereof. 【Background technique】 [0002] ABS (Acrylonitrile Butadiene Styrene) resin is an acrylonitrile-styrene-butadiene copolymer, which has high impact strength, good processing performance and chemical stability, is easy to mold, and the product is glossy and has both toughness and flexibility. Therefore, ABS resin is widely used in the automotive industry, electronic and electrical industry, light industrial appliances, textile and construction industries due to its excellent comprehensive performance, and has gradually become one of the most used thermoplastics. However, ABS resin is a kind of flammable polymer material. Its horizontal combustion speed is very fast, and a large amount of black smoke is produced when it is burned. It continues to burn after leaving the fire. It ...
