Ethylene propylene diene monomer and chloroprene rubber blended secondary closed pore foaming material and preparation method thereof

Abstract

The invention relates to a foaming material, in particular to an ethylene propylene diene monomer and chloroprene rubber blended secondary closed pore foaming material and a preparation method thereof. The foaming material is prepared from the following raw materials in parts by weight: 45-100 parts of ethylene propylene diene monomer, 45-100 parts of chloroprene rubber, 8-15 parts of carbon black, 10-18 parts of a fire retardant, 8-15 parts of magnesium powder, 10-35 parts of windsor clay, 12-25 parts of active light calcium, 25-35 parts of naphthenic oil, 0.8-2.5 parts of an anti-aging agent, 1.5-3.5 parts of an antioxidant, 2-4 parts of a foaming agent, 1.4-1.8 parts of a foaming auxiliary, 1-2 parts of a vulcanization accelerator, 2.5-5.2 parts of an activating agent, 2-6 parts of zinc oxide, 1-2 parts of a dispersing agent, and 1-2.5 parts of stearic acid. Compared with the prior art, the foaming material disclosed by the invention greatly reduces the content of halogen, meets the environment-friendly requirement and has good performances of resisting flame, aging, oil and chemical reagents at the same time.

Description

technical field [0001] The invention relates to a foaming material, in particular to a secondary closed-cell foaming material combined with EPDM rubber and chloroprene rubber and a preparation method thereof. Background technique [0002] The foaming materials currently on the market have a high halogen content, so the foaming materials will produce hydrogen halide gas when burned, which will cause suffocation of humans and animals, which is not friendly to the environment. At the same time, the existing foaming materials cannot meet higher requirements in terms of ozone resistance, aging resistance, acid and alkali resistance, weather resistance, and flame retardancy. Therefore, when developing and manufacturing these foam materials, we strive to reduce the content of halogen elements in the materials to achieve the required material effects and make them environmentally friendly products. At present, no relevant environmental protection EPDM rubber and neoprene rubber have...

Problems solved by technology

[0002] The foaming materials currently on the market, due to the high content of halogen, will produce hydrogen halide gas when the foaming materials are burned, which will cause suffocation of human and animal breathing, which is not friendly to the environment

At the same time, the existing foaming materials cannot meet higher requirements in terms of ozone resistance, aging resistance, acid and alkali resistance, weather resistance, and flame retardancy.

Therefore, when developing and manufacturing these foam materials, we strive to reduce the content of halogen elements in the materials to achieve the required material effects and make them environmentally friendly products. At present, no relevant environmental protection EPDM rubber and neoprene rubber have been found. A report on the use of secondary closed-cell foaming materials
