Problems solved by technology

In the past, the material used for automatic transmission hoses was polyethylene rubber or chlorosulfonated polyethylene rubber, but this material has poor tear resistance, temperature resistance, oil resistance, and low temperature resistance, and cannot meet the increasingly higher requirements. Use requirements and assembly requirements
Therefore, at present, the automatic transmission oil cooling pipe of high-end models is produced with acrylic rubber. The problem is that OEMs not only pay attention to the high temperature resistance and hot oil resistance of the hose, but also pay special attention to the resistance performance of the hose. This is to prevent the hose from being damaged due to electrical conduction during the work process. This has become an urgent problem in the hose industry. And a technical problem that many people are studying but still can't effectively solve

Abstract

The invention relates to an acrylic rubber composite which comprises the following components: acrylic rubber, semi-reinforced furnace black N774, silica powder 750, di adipate, cyclohexyl N-phthalimidyl sulfide, stearic acid, organic alkyl phosphate, 4,4-diphenylamine antiager Naugard 445, potassium stearate SK-1, sodium stearate SN-1 and sulfur. In the composite of the invention, due to addition of the silica powder 750, the formula cost is reduced, the physical and mechanical properties of the materials are improved and the volume resistivity of the acrylic rubber is changed. Compared with the traditional products, the difference is obvious, the tensile strength is 12.0MPa, the volume resistivity is 1*107 omega.cm which is 1*105 omega.cm higher than that of the traditional product, and the service life of the cooled tube of an automatic gearbox is prolonged. The acrylic rubber composite can preferably meet the anti-resistance performance, thermostability performance and hot oil resisting performance of rubber tubes.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a resistance-resistant acrylate rubber composition. Background technique [0002] Resistance-resistant acrylic hose mainly refers to automatic transmission hoses for automobiles. With the development of the economy and the improvement of people's living standards, cars have become one of the means of transportation for people. More and more cars use automatic transmission gear structures. Therefore, the requirements for automatic transmissions and related components are getting higher and higher. . The oil cooling system in the automatic transmission is an essential part. Its main function is to dissipate the heat generated during the working process of the automatic transmission. The coolers are connected, and the connecting part in the middle is the automatic transmission oil cooling pipe. In the past, the material used for automatic transmission hoses was polyethylene ...
