Abstract

The invention discloses tyre inner liner rubber, which adopts a sulfur-free formula and is prepared from the following components in weight part: 80-120 parts of natural rubber, 20-60 parts of halogenated butyl rubber, 10-15 parts of tread rubber powder, 10-15 parts of white carbon black, 15-25 parts of carbon black, 1-8 parts of zinc oxide, 0.2-1 part of magnesium oxide, 1-15 parts of calcium carbonate, 1-4 parts of stearic acid, 2-15 parts of softening agent, 3-5 parts of anti-aging agent, 1-4 parts of microcrystalline wax, 1-4 parts of pine tar, 1-2 parts of accelerant, 3-10 parts of binding agent and 1-3 parts of silane coupling agent. The two-stage mixing technology is adopted. The air permeability of the rubber is low, and the airtight performance of the tyre is better. As the halogenated butyl rubber is adopted, the pressure can be maintained and the tyre can be prevented from erosion by oxygen and moisture in the air.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials and rubber, in particular to a tire inner liner rubber and a preparation method thereof. Background technique [0002] With the rapid development of the automobile industry, most of the tires tend to be tubeless, and the requirements for the airtightness of the tires are getting higher and higher. Insufficient tire pressure can easily lead to serious tire wear, increased fuel consumption, and even serious traffic accidents. Effective air-tight performance can maintain normal tire pressure for a long time, prolong tire life and reduce fuel consumption. The performance of innerliner compound is an important factor affecting the airtight performance of tubeless tires. Contents of the invention [0003] The object of the present invention is to provide a kind of tire inner liner rubber and its preparation method aiming at the defects mentioned above. [0004] A kind of tire in...
