Abstract

The invention discloses an environment-friendly high-flame-retardance EPDM (ethylene-propylene-diene monomer) foaming material and a preparation method thereof. The environment-friendly high-flame-retardance EPDM foaming material comprises 100 parts of mixed rubber C, 20-25 parts of softening agent paraffin oil, 0.5-1 part of an accelerant DM, 2-3 parts of a foaming aid, 3-5 parts of a foaming agent and 1.5-3 parts of sulfur. The mixed rubber C is prepared from the following components: 30-40 parts of premixed rubber A, 100 parts of premixed rubber B, 3-5 parts of stearic acid, 10-15 parts of zinc oxide, 130-140 parts of a flame retardant, 100-130 parts of carbon black, 6-8 parts of polyethylene glycol and 3-5 parts of a flow dispersant. The premixed rubber A comprises 50 parts of high styrene resin, 50 parts of ethylene propylene diene monomer 7001 and 1-2 parts of stearic acid. The premixed rubber B is prepared from 25 parts of ethylene propylene diene monomer 7001, 100 parts of ethylene propylene diene monomer 3080P and 1-2 parts of stearic acid. According to the environment-friendly high-flame-retardance EPDM foaming material disclosed by the invention, when a sample of the environment-friendly high-flame-retardance EPDM foaming material is 0.9 mm, a vertical combustion test is carried out, and the environment-friendly high-flame-retardance EPDM foaming material meets the V-O grade.

Description

technical field [0001] The invention relates to the technical field of polymer preparation, in particular to an environment-friendly high flame-retardant EPDM foam material and a preparation method thereof. Background technique [0002] Ethylene Propylene Diene Monomer (EPDM) is widely used in automobiles, electronics, electrical appliances, aviation, aerospace, construction and other industries because of its excellent weather resistance, ozone resistance, heat resistance, electrical insulation and chemical medium corrosion resistance. . In recent years, with the continuous acceleration of my country's industrialization process, its demand is also rising sharply. With the emphasis on environmental protection requirements and the improvement of flame retardant requirements in various environments, quite a lot of application fields have clear environmental protection requirements for flame retardant materials. , The requirements for flame retardancy of thin products are getti...
