High-strength wear-resisting flame-retardant modified ethylene-propylene-diene monomer rubber and preparation method thereof

Abstract

The invention discloses high-strength wear-resisting flame-retardant modified ethylene-propylene-diene monomer rubber. The high-strength wear-resisting flame-retardant ethylene-propylene-diene monomer rubber is prepared from the following raw materials in parts by weight: 36-44 parts of ethylene-propylene-diene monomer rubber, 20-25 parts of chlorinated butyl rubber, 18-24 parts of natural rubber, 0.8-1.5 parts of a vulcanizing agent LH-C96, 0.5-1.5 parts of N,N'-1,3-Phenylenedimaleimide, 1.5-1.8 parts of an accelerant TMTD (Tetramethylthiuram Disulfide), 2-4 parts of magnesium oxide, 1-3 parts of stearic acid, 5-10 parts of trioctyl trimellitate, 2.5-4 parts of an environment-friendly flame retardant FR-T 801, 0.8-1.6 parts of antimony trioxide, 20-40 parts of modified titanium dioxide, 15-30 parts of coal gangue powder, 20-30 parts of calcined clay, 1.2-1.5 parts of a monoalkoxy pyrophosphate type titanate coupling agent, 1.3-1.8 parts of an antiager 800-B, and 1.5-2.1 parts of an antiager BLE (High temperature condensation compound of diphenylamine and acetone). The invention further discloses a preparation method of the high-strength wear-resisting flame-retardant modified ethylene-propylene-diene monomer rubber.

Description

technical field [0001] The invention relates to the technical field of EPDM rubber, in particular to a high-strength wear-resistant and flame-retardant modified EPDM rubber and a preparation method thereof. [0002] Background technique [0003] EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated dienes. It has excellent resistance to oxidation and ozone. EPDM rubber is non-polar and resistant to polar solutions and chemicals. properties, low water absorption, so it has good insulation and strong corrosion resistance, and because EPDM rubber belongs to the polyolefin family, it has excellent vulcanization characteristics; among all rubbers, EPDM rubber has the lowest proportion. It can absorb a large amount of fillers and oils without greatly affecting its properties, so it can be made into low-cost rubber compounds; however, its strength is not high, its wear resistance is not good, and in actual use, its flame retardancy is lacking, which is harmful to...
