Abstract

The invention provides a flame-retarding toughening polystyrene master batch and a preparation method thereof, which can achieve the purposes of being high in flame resistance rate and free of dust in production environments. The technical scheme is that the master batch comprises the following components, by mass: 25-35 parts of polystyrene, 10-20 parts of styrene-butadiene- styrol copolymers, 15-25 parts of decahromopdipenyl ethane, 15-25 parts of brominated epoxy resin, 8-14 parts of antimonous oxide, 0.2-0.6 parts of lubricant zinc stearate, 0.3-0.8 parts of lubricant ethylene bis stearamide, 0.3-0.6 parts of calcium oxide, 0.1-0.3 parts of polytetrafluoroethylene and 0.2-0.4 parts of antioxygen. The flame-retarding toughening polystyrene master batch can be directly mixed with high impact polystyrene (HIPS) resin to produce plastic injection parts. The flame-retarding toughening polystyrene master batch with different contents can produce products with various flame-retarding grades, and is wide in application, convenient and fast.

Description

technical field [0001] The invention relates to materials, in particular to a flame-retardant and toughened polystyrene masterbatch and a preparation method thereof. Background technique [0002] At present, among the flame retardants used in HIPS, brominated flame retardants are the most used. The addition amount of this type of flame retardant is relatively small, the compatibility is good, and the flame retardant effect is obvious. [0003] After the European Union and other organizations put forward environmental protection requirements, such as RoHS and other laws and regulations, decabromodiphenylethane has become the main flame retardant currently used. It has high bromine content, good thermal stability, and antimony trioxide (Sb 2 o 3 ) can produce a synergistic response. When decabromodiphenylethane burns, it can generate hydrogen bromide, which can effectively capture the free radicals generated during the combustion reaction of materials. 2 o 3 It reacts wit...
