Long-service life durable environmental-protection vehicle inner tube material

Abstract

The present invention discloses a long-service life durable environmental-protection vehicle inner tube material, which is prepared from the following raw materials by weight: 0.5-1.5 parts of sulphur powder, 0.2-0.3 part of an accelerator CZ, 40-50 parts of compounding intercalation modification powder, 30-45 parts of a butyl rubber, 15-20 parts of carbon black, 0.3-1 part of an anti-aging agent AW, 15-25 parts of butyl rubber scrap tire, 1-3 parts of POE, 1-2 parts of polyisobutylene, 10-14 parts of a chloroprene rubber, 4-6 parts of polyacrylate, 0.5-2 parts of dioctyl adipate, 10-13 parts of calcined pot clay, 2-4 parts of hydrated zinc borate, 1-3 parts of N-tert-butyl-2-benzothiazole sulfenamide, 1-2 parts of an anti-aging agent 4010, 2-4 parts of trioctyl trimellitate, 3-7 parts of calcium stearate, and 1-2 parts of cashew nut shell oil. According to the present invention, the anti-aging agent compounding and the reasonable matching of the remaining raw materials are performed to prepare the inner tube material, and the long-service life durable environmental-protection vehicle inner tube material has characteristics of smooth appearance, good hand feeling, high strength, high aging resistance and high resilience.

Description

Technical field [0001] The invention relates to the field of inner tubes, specifically a durable and environmentally-friendly automobile inner tube material with long service life. Background technique [0002] The inner tube is commonly called the inner tube. Refers to a circular elastic tube with tire valve used to maintain the internal pressure of the tire. The valve is used to inflate and maintain a certain pressure of air in the inner tube. The inner tube should have good air tightness, heat resistance, elasticity, aging resistance and small permanent deformation. Generally made of butyl rubber. [0003] Butyl rubber is a type of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. It is generally used in the production of automobile tires and automobile sound insulation products. Now butyl rubber has been widely used instead of asphalt with the name of environmental protection. [0004] Butyl rubber inner tube has good self-closing perfo...

Problems solved by technology

[0005] At present, the output of butyl rubber in my country is extremely low, and the supply is in short supply. The existing butyl reclaimed rubber and other POE inner tube materials have poor performance. It is urgent to find a new material for inner tubes that reduces the amount of fixed base rubber.
