Embodiment 1

[0017] The rubber formula of the lower layer of the inner liner of the radial tire: 80 parts of halogenated butyl rubber, 20 parts of natural rubber, 80 parts of carbon black (660), 3 parts of stearic acid, 4 parts of zinc oxide, antioxidant (RD) 1.5 parts, sulfur 1.2 parts, accelerator (NOBS) 1.5 parts.

[0018] Upper rubber coating formula: 80 parts of natural rubber, 20 parts of styrene-butadiene rubber, 70 parts of carbon black (550), 6 parts of zinc oxide, 2 parts of stearic acid, 2 parts of antioxidant (AW), 2 parts of sulfur, accelerator (NS) 1.5 parts.

[0019] Mix the rubber base material, anti-aging system, reinforcing system, and vulcanization system with an internal mixer according to the above formula. The mixing temperature is controlled at 40-100°C, and the mixing time is about 25 minutes. After the rubber is mixed evenly, Glue removal; after parking for 8-12 hours, add the vulcanization system to the open mill to complete the preparation of the mixed rubber. ...

Embodiment 2

[0022] The rubber composition of the lower layer of the inner inner liner of the radial tire: 90 parts of halogenated butyl rubber, 10 parts of natural rubber, 80 parts of carbon black (660), 4 parts of stearic acid, 3 parts of zinc oxide, antioxidant (RD) 2 parts, 0.8 parts of sulfur, 1.2 parts of accelerator (NOBS).

[0023] The formula of rubber coating on the inner inner liner of radial tire: 90 parts of natural rubber, 10 parts of butadiene rubber, 70 parts of carbon black (550), 6 parts of zinc oxide, 2 parts of stearic acid, 2 parts of anti-aging agent (AW) , 1.8 parts of sulfur, 1.3 parts of accelerator (NS).

Abstract

The invention discloses a a preparation technique for radial tire liner airtight layer part comprising lower layer substrate rubber and upper layer coating glue. A rubber substrate, an anti-aging system, a vulcanizing system and a radiation crosslinking sensitizer are mixed into a mixture in proportion; the rubber mixture is respectively mixed in an internal mixer and manufactured into the radial tire liner airtight layer part according to the production technique of the tire liner airtight layer part. A beam current generated by an electron accelerator is used for carrying out irradiation treatment on the tire liner airtight layer part on a lower device without a traction beam; under the condition of limited oxygen radiation, the radiation pre-curing treatment on the tire liner airtight layer part of the radial tire is accomplished. The liner airtight layer part treated by radiation of the invention has a high green intensity and a high bonding intensity, has stable structure size and performance, reduces the thickness of the rubber layer of the part, can improve the quality of the tire, saves the materials, has a small irradiation dose, has a high production efficiency and is beneficial to protecting the environment.

Description

Technical field [0001] The invention relates to the technical field of rubber tire processing, in particular to a preparation process of a radial tire inner liner inner liner component. technical background [0002] At present, the automobile tire industry is developing rapidly, and various new tires such as safety tires, energy-saving tires, high-performance tires, and green tires have appeared successively. As an important support and strategic resource for the transportation industry, tires have been highly valued by various countries. Tires are composed of multiple parts with rubber material as the main base material after vulcanization and shaping. The tubeless radial tire is the development trend of the tire, that is, in the tire structure, the inner tube is canceled, and the inner side of the whole tire is added with an airtight layer. In addition to protecting the carcass layer, its function is mainly to prevent the pneumatic tire from seeping out of the carcass lay...
