Abstract

The invention discloses an antibacterial halogen-free flame-retardant PC / ABS composite material with high ball pressure temperature. The composite material mainly comprises the following components in parts by mass: 59-88 parts of PC, 520 parts of ABS, 4-12 parts of an organophosphorus flame retardant, 2-5 parts of a flexibilizer, 0.4-1 part of an antibacterial agent, 0.2-0.5 part of an anti-dripping agent, 0.2-1 part of a dispersing agent and 0.2-1 part of an antioxidant. The halogen-free flame-retardant PC / ABS composite material is good in antibacterial property, high in ball pressure resistant temperature, good in flame retardant property and white in color, various bright-colored products can be manufactured by adding the coloring agent, no halogen flame retardant is adopted, the flame retardant grade of the material is high, cost is low, smell is small, and large-area application and popularization are facilitated. The invention also discloses a preparation method of the composite material. The preparation method is simple to operate, low in cost, short in preparation period and convenient for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic polymer materials, and in particular relates to an antibacterial and high ball pressure temperature halogen-free flame-retardant PC / ABS composite material and a preparation method thereof. Background technique [0002] PC / ABS is an alloy material formed by blending PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene copolymer) resin in a certain proportion. It has excellent heat resistance, toughness, mechanical Performance, thermal stability and dimensional stability, it has been widely used in automotive interior and exterior parts, household appliances, consumer electronics and communication equipment and other fields. Since both PC and ABS materials are flammable or flammable materials, the greater the amount and scope of their use, this will bury safety hazards for fire prevention. Therefore, flame-retardant polymer materials are promoted in more application fields. Due to the ...
