Abstract

The invention discloses vulcanized resin pre-dispersed masterbatch particles for tire capsules. The vulcanized resin pre-dispersed masterbatch particles for tire capsules is prepared from the following components in parts by weight: 40 to 70 parts of isobutylene, 2 to 5 parts of dispersant, 15 to 30 parts of inorganic silicone material, 15 to 30 parts of masterbatch carrier, 20 to 40 parts of dilauryl dithiodipropionate, 10 to 30 parts of ultra-fine calcium carbonate, 30 to 50 parts of 4-methyl-2-pentanone and 10 to 20 parts of 4-aminodiphenylamine. The vulcanized resin pre-dispersed masterbatch particles for tire capsules and the preparation method thereof have the advantages of reasonable formula, easiness in preparation, excellent heat resistance, oxidation resistance, flexural resistance, alkali resistance, freeness from pollution, health, environmental friendliness and low cost.

Description

technical field [0001] The invention belongs to the technical field of tire bladders, and more specifically relates to a vulcanized resin predispersed masterbatch particle for tire bladders. At the same time, the invention also relates to a preparation method of vulcanized resin predispersed masterbatch particles for tire bladders. Background technique [0002] The tire bladder is mainly a tool for tire vulcanization. The material is butyl rubber, which is equivalent to the inner mold of the tire mold. Capsules are divided into different models according to different vulcanizing machines and fixtures. Its function is mainly to fill the interior with compressed air, nitrogen or superheated water during the tire vulcanization process. Stretch it to prop up the tire rubber embryo to form an internal pressure vulcanized tire. Among them, vulcanized resin pre-dispersed masterbatch is an important raw material for tire bladders, but the preparation of traditional vulcanized res...
