Embodiment １

[0016] The inner tube rubber of a tubeless tire is composed of the following components by weight fraction: styrene-butadiene rubber 60, chloroprene rubber 40, nitrile rubber 20, carbon black 30, zinc oxide 5, magnesium oxide 2, sulfur 6 , Stearic acid 2, softener 10, anti-aging agent 4, microcrystalline wax 2, urethane 3, accelerator 2, binder 7.

[0017] The carbon black is carbon black N660.

[0018] Described anti-aging agent is anti-aging agent RD and anti-aging agent 4020.

[0019] The mass ratio of antioxidant RD and antioxidant 4020 is 1:2.

[0020] The softener is naphthenic oil.

[0021] The accelerator is composed of accelerator DM and accelerator CZ according to the mass ratio of 1:1.

[0022] The binder is a mixture of hydrocarbon resins.

[0023] The lower the air permeability of the rubber, the better the airtight performance of the tire, and it also has good oil resistance and heat resistance. Adopting the rubber of the invention can maintain the pressure ...

Abstract

The invention discloses inner liner rubber for a tubeless tire. Butadiene styrene rubber is added, has a good anti-ageing property and heat resistance and has more uniform texture than natural rubber; additionally, chloroprene rubber is added, rubber molecules contain chlorine atoms, and the chloroprene rubber has good anti-oxidant and ozone-resistant properties, is nonflammable, can be self-extinguished after being ignited and has good oil resistance, solvent resistance, acid-base resistance, ageing resistance and air tightness; acrylonitrile-butadiene rubber has great gasoline and aliphatic hydrocarbon oil resistance, good heat resistance, relatively good air tightness, wear resistance, water resistance and the like and high bonding force. Besides, other auxiliary ingredients are added, the prepared inner liner rubber for the tubeless tire is low in air transmittance, the tire has good air tightness, good oil resistance and heat resistance, and requirements of the inner liner rubber for the tubeless tire can be fully met.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber for the inner liner of a tubeless tire. Background technique [0002] With the rapid development of the automobile industry, the requirements for airtightness of tires are getting higher and higher, and with the needs of factors such as climate and environment, there are certain requirements for the oil resistance and heat resistance of tires. 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. How to improve the formula of the rubber compound to improve the airtightness, oil resistance and heat resistance of the rubber is a technical problem to be solved in the present invention. Contents of the invention [0003] The objective of the present invention is exactly ...
