Abstract

The invention relates to a high-pressure-resistance abrasion-resistance dustproof capsule and a preparation process thereof. The dustproof capsule is prepared from the following raw materials in parts by weight: 85-90 parts of hydrogenated butadiene-acrylonitrile rubber, 15-20 parts of chlorinated butyl rubber, 5-10 parts of natural rubber, 5-10 parts of zinc oxide, 1-2 parts of magnesium oxide, 1-2 parts of stearic acid, 0.5-1 part of paraffin, 30-40 parts of N330 carbon black, 5-15 parts of N770 carbon black, 10-15 parts of white carbon black, 3-5 parts of solid coumarone resin, 1-2 parts of adhesive A, 2-3 parts of adhesive RS, 1-3 parts of accelerant NOBS, 1-3 parts of accelerant TMTD, 1-3 parts of accelerant CZ, 1-3 parts of sulfur, 1-3 parts of a vulcanizing agent, 1-2 parts of a co-curing agent HVA, 5-10 parts of TP759, 1-2 parts of an internal releasing agent and 3-5 parts of an antiaging agent. The dustproof capsule has the advantages of high pressure resistance and abrasion resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-pressure-resistant, wear-resistant and dust-proof capsule and a preparation process thereof. Background technique [0002] In the process of steelmaking in steel mills, a large amount of useless dust is generated. Under the reality of increasingly serious environmental protection requirements, dust treatment is particularly important. The rubber capsule is inflated and pumped in the pipeline to make it expand and close to control the dust recovery. Due to the softness and expandability of the rubber capsule, it fits and tightens well with the pipeline, so that it expands and seals tightly. It will cause dust leakage. When it is tightened, the pipeline will be unblocked and the dust can pass through quickly. [0003] Chinese patent CN105837963A discloses a butyl rubber composite material used in vulcanization bladders, which is composed of butyl rubbe...
