Flame-retardant hardware plastic material and preparation method thereof

Abstract

The invention belongs to the field of materials, and specifically relates to a flame-retardant hardware plastic material and a preparation method thereof. The flame-retardant plastic material comprises the following components in parts by mass: 70-88 parts of an ethylene-vinyl acetate copolymer, 10-13 parts of expanded polystyrene, 6-7 parts of borax, 6-8 parts of polycyclobutylene terephthalate,3-5 parts of anhydrous copper sulfate, 2-4 parts of activated aluminum hydroxide, 2-7 parts of maleic anhydride modified polyethylene, 4-10 parts of titanium dioxide, 3-5 parts of polyester fiber, 3-5parts of short asbestos fiber, 1-3 parts of aniline, 2-4 parts of barium stearate, 2-3 parts of a toughener, 4-8 parts of a composite flame retardant, 3-4 parts of an antistatic agent, 3-4 parts of an antioxidant, 2-4 parts of a compatibilizer and 1-2 parts of a lubricating demoulding agent. The flame-retardant plastic material prepared according to the preparation method provided by the invention is excellent in performance and free of toxic substances; furthermore, the production process is environmentally friendly; in addition, the prepared flame-retardant plastic material is good in flameretardance, resistant to high temperature, stable in thermal deformation size and high in melting point.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a flame-retardant hardware and plastic material and a preparation method thereof. Background technique [0002] Hardware and plastic parts refer to machine parts or components made of plastic. The same traditional parts made of hardware have similar strength but low density and similar mechanical properties. Hardware and plastic parts can be used alone or as auxiliary tools. [0003] The invention patent with the application number 201610573953.6 discloses a metal plastic part, which is mainly composed of the following components in parts by mass: 60-100 parts of ethylene-vinyl acetate copolymer, 5-10 parts of expanded polystyrene, 6-7 parts of borax, 3-5 parts of clarifying agent, 3-5 parts of anhydrous copper sulfate, 2-4 parts of activated aluminum hydroxide, 2-4 parts of maleic anhydride modified polyethylene, 4-10 parts of titanium dioxide, poly 3-5 parts of ester fibe...
