Abstract

The invention belongs to the technical field of rubber tires and chemical manufacturing, and relates to a rubber composition specially suitable for producing a semi-steel radial tire inner liner and a preparing method thereof. The rubber composition is prepared from, by weight, 30-40 parts of natural rubber, 60-70 parts of brominated butyl rubber, 60-70 parts of carbon black, 30-40 parts of reinforcing powder, 10-12 parts of environment-friendly aromatic oil, 4-6 parts of an active agent, 2-4 parts of tackifier resin, 2-4 parts of a dispersing agent, 0.2-0.5 part of magnesium oxide, 1-2 parts of a promoting agent and 1-1.8 parts of sulfur. As two-section rubber mixing is adopted, energy consumption is saved, and transportation and transferring of the production link are reduced; the flowing performance of rubber is improved in the pressing technology process, and particularly, air bubbles of a pressing part are obviously reduced, and the once pass percent of a product is improved; the low preparing cost and the high processability are achieved while the rubber composition for producing the semi-steel radial tire inner liner can meet the requirement for the high breathability resistance of the rubber.

Description

technical field [0001] The invention belongs to the technical field of rubber tires and chemical manufacturing, and relates to a rubber composition especially suitable for producing semi-steel radial tire inner liners and a preparation method thereof, which meets the requirements of the tire inner liner for rubber with high air permeability resistance and realizes its Low cost and high processability of preparation. Background technique [0002] Modern tubeless pneumatic tires are highly ingeniously designed products made up of multiple specialized components with different properties. The airtight layer is one of these components. Its function is to seal the air, minimize the diffusion of air from the tire, help maintain the proper inflation pressure of the tire, and thus eliminate the negative effects of tire underinflation, such as Improve tire rolling resistance, reduce vehicle fuel economy, reduce tire durability, reduce tire handling performance and driving performanc...
