Antifreeze rubber inner tube material

Abstract

The invention discloses an antifreeze rubber inner tube material. The antifreeze rubber inner tube material is made of the following raw materials in parts by weight: 30-40 parts of butyl rubber, 10-20 parts of waste butyl rubber inner tubes, 10-20 parts of silicone rubber, 40-50 parts of compound intercalation modification powder, 2-4 parts of coumdrone indene resins, 5-10 parts of microcapsulated red phosphorous, 2-3 parts of sulfur powder, 0.7-1.4 parts of accelerator, 3-5 parts of castor oil, 2-5 parts of turpentine, 5-10 parts of carbon nanotubes, 2-3 parts of slime, 5-8 parts of SBS resin, 25-40 parts of talcum powder, 0.3-0.5 parts of antioxidant 1010 and 0.3-0.6 parts of antioxidant 1024. An inner tube prepared by using the antifreeze rubber inner tube material provided by the present invention has good freezing resistance, can be used in cold areas, has good safety, is not likely to break and is wide in application scope, long in service life, high in surface softness, low in smoke and nontoxic during combustion and good in mechanical properties.

Description

technical field [0001] The invention relates to the field of inner tubes, in particular to a frost-resistant rubber inner tube material. Background technique [0002] The inner tube is commonly known as the inner tube. Refers to a circular elastic tube with a tire valve for maintaining 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 kind of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. It is generally used in the production of car tires and car sound insulation products. Now butyl rubber has been widely used to replace asphalt in the name of environmental protection. [0004] Butyl rubber inner tube colloid has good self-closing performance and high air tightness. After th...

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 natural rubber inner tube materials have poor performance. It is urgent to find a new material for inner tubes that can reduce the amount of fixed base rubber.
