Embodiment

[0033] A high-viscosity tire inner liner sizing compound composition, the components of the sizing compound composition and the parts by weight of the content thereof are:

[0034] Bromobutyl gum 80

[0035] 1742 butyl rubber 20

[0036] Carbon black N660 35

[0037] Diatomaceous earth 25

[0038] Magnesium oxide 0.6

[0039] Stearic acid 1.3

[0040] 4m2 zinc oxide 3

[0041] 2 resin 6

[0042] Naphthenic oil 6.5

[0043] Promote DM 1.6

[0044] 7020 sulfur 0.63

[0045] The production of rubber material is divided into two stages of mixing production. The first stage of rubber material formula adds bromobutyl rubber, 1742 butyl rubber, carbon black N660, diatomaceous earth, magnesium oxide, stearic acid, 4m2 zinc oxide, 2 resins, and the rest The compounding agent is added in the second-stage rubber formula. The two-stage rubber materials are mixed and manufactured in the internal mixer respectively, then pounded on the tablet press, and then the tablets are cooled...

Abstract

The invention discloses a high viscosity rubber composite of a tire airtight layer. The rubber composite comprises following components: brominated butyl rubber, 1742 butyl rubber, carbon black N660, diatomite, magnesium oxide, stearic acid, 4m2 zinc oxide, 2 resin, naphthenic oil, promoter DM and 7020 sulfur. Diatomite is added in the rubber composite of a tire airtight layer, the shortages of easy material breaking in the process of airtight layer calendering, and bad viscosity in the process of forming and fitting are overcome, viscosity is largely improved, and the viscosity between the airtight layer and the seam allowance rubber compound is prominently improved in the process of forming.

Description

technical field [0001] The invention relates to a rubber compound for a tire inner liner, in particular to a high-viscosity tire inner liner compound composition. Background technique [0002] With the continuous strengthening of the country's economic strength, the automobile industry has developed rapidly. Automobiles have become an indispensable and important means of transportation for people's lives. The development of the automobile industry has directly promoted the technological innovation and progress of the tire industry. Recently, due to the society's strong demand for low fuel consumption of automobiles, a low-heat and light-weight tire has been designed, and in tire components, a light-weight inner liner located inside the tire is also used, which has The function of reducing the amount of air leaking from the inside of the pneumatic tire to the outside improves the airtightness, mainly by using a rubber composition containing butyl rubber and diene rubber in th...
