Problems solved by technology

[0003] The low-halogenated butyl rubber technology has low cost, but it has high air permeability and large tire pressure loss during use, and the tire deformation increases during driving, and flex cracks are prone to occur at the bead, and local heat generation leads to aging and delamination. eventually lead to tire damage
[0004] High halogenated butyl rubber technology increases the amount of halogenated butyl rubber to reduce the air permeability of the tire, but the processing dispersion of halogenated butyl rubber is poor, making it difficult to glue, which affects extrusion and molding operations
As the content of halogenated butyl rubber increases, the vulcanized adhesion of adjacent different types of rubber decreases, and the layer is easy to separate during driving, resulting in damage to the inner layer of the tire

Abstract

The invention provides high-gas-maintaining-performance inner surface rubber, which comprises the following ingredients in parts by weight: natural rubber, emulsion polymerized styrene butadiene rubber, chlorinated butyl rubber, high-wear-resistance carbon black, general furnace black, flaky nanokaolin, chemical anti-aging agents BLE-W, active agents of ZnO, active agents of stearic acid, tackifying resin RT-1102, sulfurization agents S-325, promoting agents TB710, promoting agents TBBS, promoting agents TMTD and operation oil TDAE-22. The high-gas-maintaining-performance inner surface rubber has the advantages that the cost is low; the gas maintaining performance is high; the processing dispersivity and the adhesive property are improved; the physical performance is also improved; meanwhile, the consumption on petroleum products is also reduced; certain environment-protection effects are achieved.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to a high gas-holding inner surface rubber and a synthesis method thereof. Background technique [0002] Automobile tire inner liner rubber is prepared from halogenated butyl rubber with low air permeability. At present, two technologies are usually used: one is low-halogenated butyl rubber technology, and the other is high-halogenated butyl rubber technology. [0003] The low-halogenated butyl rubber technology has low cost, but it has high air permeability and large tire pressure loss during use, and the tire deformation increases during driving, and flex cracks are prone to occur at the bead, and local heat generation leads to aging and delamination. Eventually lead to tire damage. [0004] The high halogenated butyl rubber technology increases the amount of halogenated butyl rubber to reduce the air permeability of the tire, but the processing dispersion of halogenated butyl rubb...
