Abstract

The invention discloses flame-retardant ABS (Acrylonitrile-Butadiene-Styrene copolymer) modified plastics. The flame-retardant ABS modified plastics contain the following substances in parts by weight: 100 parts of ABS, 5-10 parts of inorganic filler, 0.5-2 parts of vinyl triethoxysilane, 1-3 parts of di(methyl o-formate phenol)ethanolamine aluminate, 1-2 parts of nano aluminum hydroxide, 0.1-0.8 part of acetyl dibutyl-octyl citrate and 1-2 parts of phthaloyl dioctyl ester. The flame-retardant ABS modified plastics prepared by the invention have the characteristics of low flame retardant addition level, good flame-retardant effect, high stability and good dispersity.

Description

technical field [0001] The invention belongs to the technical field of modified plastics, and in particular relates to a flame-retardant ABS modified plastic. Background technique [0002] In recent decades, plastics, rubber, synthetic fibers and other polymer materials and their products have developed vigorously. They are rapidly replacing traditional steel, metal, cement, wood, cotton and other natural polymers, and are widely used in industry and agriculture. , military and other sectors of the national economy. They have improved people's lives and have become necessary for people. In 2000, the production volume of plastic reached 170 million tons, and its volume greatly exceeded the volume of steel produced in the same year. However, most polymers are flammable and combustible materials. When burning, the heat release rate is high, the calorific value is high, the flame spreads fast, and it is not easy to extinguish. Life safety poses a huge threat. Therefore, how ...
