Embodiment Construction
[0023] Below in conjunction with embodiment the present invention is described in further detail.
[0024] The invention belongs to a technological innovation in the field of automobile synchronous belt products. The preferred rubber type of traditional automobile synchronous belts is usually hydrogenated nitrile butadiene rubber or neoprene. Chlorosulfonated polyethylene rubber is considered to have poor dynamic properties and is abandoned. The present invention can produce chlorosulfonated polyethylene rubber with excellent chlorine content and Mooney viscosity as the base material and optimize its formula. performance automotive timing belts. A chlorosulfonated polyethylene automobile synchronous belt of the present invention is made of a mixed braided adhesive tape layer, a glass wire reinforcement layer and a chlorosulfonated polyethylene rubber layer after molding, vulcanization, grinding and cutting; the composition of the chlorosulfonated polyethylene rubber layer Raw...

Abstract
The invention discloses a chlorosulfonated polyethylene automobile synchronous belt and a manufacturing method thereof. The synchronous belt is formed by forming, vulcanizing, grinding and cutting a mixed knitting adhesive tape layer, a glass thread reinforcing layer and a chlorosulfonated polyethylene rubber layer, wherein the chlorosulfonated polyethylene rubber layer comprises, by mass, 100 parts of chlorosulfonated polyethylene rubber, 1.0-2.5 parts of N,N'phenylene bismaleimide, 4.0-12.0 parts of high-activity magnesium oxide, 0.5-1.8 parts of stearic acid, 2.0-5.0 parts of dicumyl peroxide, 40-60 parts of N550 carbon black, 0.5-2.0 parts of Diisobutylthiuram disulfide, 8.0-14.0 parts of 810 ester and 0.5-1.5 parts of xanthogenate. The synchronous belt has the advantages of being simple in manufacturing process, low in product cost, high in cost performance, environmentally friendly and long in service life.
Description
technical field [0001] The invention relates to the technical field of automobile synchronous belt manufacture, in particular to a chlorosulfonated polyethylene automobile synchronous belt and a manufacturing method thereof. Background technique [0002] Chlorosulfonated polyethylene rubber is a product obtained by first chlorination and then chlorosulfonation of polyethylene. Its main chain is highly saturated and has excellent high temperature resistance and ozone resistance. The presence of chlorine makes it also excellent in oil resistance. Widely used in automotive hydraulic hoses, oil-resistant seals, wires and cables, and other fields. The traditional view is that chlorosulfonated polyethylene rubber is easy to crystallize and has poor dynamic performance, so it is not suitable for use in dynamic fields. For example, its application in the field of automobile transmission belts has been denied. However, with the progress of chlorosulfonated polyethylene synthesis tec...
