Abstract

The invention discloses an anti-flaming aging-resistant rubber material which comprises the following constituents in parts by weight: 40 parts to 45 parts of butadiene styrene rubber, 30 parts to 36 parts of polyurethane elastomer, 10 parts to 15 parts of chlorinated butyl rubber, 2 parts to 3 parts of vulcanizing agent BPO, 1.2 parts to 1.8 parts of sulphur, 2 parts to 4 parts of divinyl carboxylic acid sodium, 20 parts to 30 parts of calcite powder, 9 parts to 11 parts of kieselguhr, 5 parts to 7 parts of aluminum silicate, 14 parts to 15 parts of carbon black N660, 14 parts to 15 parts of carbon black N330, 10 parts to 12 parts of magnesium hydroxide, 3 parts to 5 parts of quartz powder, 5 parts to 7 parts of zinc oxide, 2 parts to 4 parts of calcium stearate, 5 parts to 8 parts of barium stearate, 5 parts to 7 parts of diphenyl phosphate ester, 2 parts to 4 parts of melamine, and 1.5 parts to 2.5 parts of silane coupling agent KH450. The anti-flaming aging-resistant rubber material has an excellent anti-flaming aging-resistant performance, so that smog is effectively prevented from generating during a combustion process; besides, the ozone resistance and the weather resistance of the anti-flaming aging-resistant rubber material are excellent; moreover, the anti-flaming aging-resistant rubber material further has the advantages of high elasticity, high hardness and high strength.

Description

technical field [0001] The invention relates to the field of technical rubber materials, in particular to a flame-retardant and aging-resistant rubber material. Background technique [0002] The aging of rubber products is a very prominent problem in the application of rubber materials. During the placement and use of rubber materials, problems such as stickiness, softening, discoloration, hardening and brittleness will occur, resulting in changes in physical and mechanical properties. It is often accompanied by high temperature during use, so good flame retardant performance is required. With the increase of the status of rubber materials in life, the service life of rubber is more and more valued by people. In order to prevent the flame retardancy, aging or improve the aging resistance of rubber materials, people make rubber products from raw rubber. In the process, various compounding components are added, and various compounding agents have a great influence on the flam...
