Abstract

The invention relates to the technical field of rubber and plastic products, and provides a non-combustible rubber and plastic foamed product with combustion performance reaching grade A. The non-combustible rubber and plastic foamed product comprises the following components in parts by weight: 10-15 parts of nitrile rubber, 4-7 parts of polyvinyl chloride resin, 8-12 parts of filler, 2-3 parts of a modified flame retardant, 2-4 parts of protective wax, 4-7 parts of a foaming agent, 0.2-0.5 part of an active agent, 1-3 parts of an accelerant and 0.1-0.3 part of a vulcanizing agent. The modified flame retardant is prepared from the following components in parts by weight: 100 parts of magnesium hydroxide, 1 part of methacryloxy propyl trimethoxy silane, 20 parts of triethyl phosphate and 0.5 part of fatty alcohol-polyoxyethylene ether. According to the technical scheme, the problems that in the prior art, the flame retardant magnesium hydroxide is non-uniformly dispersed in rubber and plastic products and is easy to agglomerate are solved.

Description

technical field [0001] The invention relates to the technical field of rubber and plastic products, in particular to a non-combustible rubber and plastic foam product with combustion performance reaching Class A and a preparation method thereof. Background technique [0002] Rubber and plastic foam products are made of nitrile rubber and polyvinyl chloride resin as the main raw materials, together with various auxiliary materials, blended at high temperature, and then added with vulcanizing agent and foaming agent to vulcanize and foam the closed-cell elastic material. Due to its unique chemical structure, rubber and plastic foam products are flammable products, and melt droplets will be produced during the combustion process. In order to meet the requirements of flame retardancy in use, it is mainly used to add flame retardants to make the products of combustion block air and combustible gas, so as to improve the flame retardancy of products. [0003] At present, the flame...
