Abstract

The invention provides a preparation method for an organic silicon flame retardant for ABS resin. The preparation method comprises the following steps: performing reaction on dimethyl siloxane, gamma-methacryloxypropyltrimethoxysilane (KH-570) and a composite catalyst at a proper temperature, performing distillation, purifying a product and removing an unreacted monomer to obtain the product.

Description

technical field [0001] The invention relates to a method for preparing a flame retardant, in particular to a method for preparing a silicone flame retardant used in ABS resins. Background technique [0002] ABS resin is currently the polymer with the largest output and the most widely used. It organically unifies the various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigid phase balance. ABS is a terpolymer of acrylonitrile, butadiene and styrene, A stands for acrylonitrile, B stands for butadiene, and S stands for styrene. Widely used in the electrical industry, automobile industry, electronic product industry, construction industry, pharmaceutical industry, etc. Adding flame retardants during the preparation of ABS can improve the flame retardant performance of plastic products, reduce the smoke of plastic products when they burn, and improve Security and stability of related industries.
