Abstract

The invention discloses a high-temperature oil-resistant chlorosulfonated polyethylene rubber tube, which comprises the following components: chlorosulfonated polyethylene rubber (CSM TS-830), fast extruding furnace black (FEF N550), diatomaceous earth C400, NycoflexADB30, activated magnesium oxide, stearic acid, SRP66, Naugard445, pentaerythritol (pasty), tetrabenzylthiuramdisulfide and N,N'-M-phenyl dimaleimide. The produced high-temperature oil-resistant chlorosulfonated polyethylene rubber tube has optimal material performance: the hardness is 70+ / 5 degrees, the tensile strength is greater than 10 MPa, elongation at rupture is greater than 200 percent and IRM903 oil-resistant weight change is lower than 60 percent; compared with a conventional product, the high-temperature oil-resistant chlorosulfonated polyethylene rubber tube has the advantages that the performance is greatly improved, and a requirement for resistance to high-temperature oil is met.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a high temperature resistant oil chlorosulfonated polyethylene rubber hose. Background technique [0002] As we all know, nitrile rubber (NBR) has excellent oil resistance, but NBR is limited by temperature, and can only resist oils with a temperature below 120 °C. Acrylic resin rubber (ACM) also has excellent high temperature resistance, especially when it is resistant to high temperature oil at 160-180 ° C, it shows good oil resistance. If ACM is used for high-temperature oil with a resistance temperature of 130-150°C, it will cause a certain amount of waste and increase production costs. High temperature resistant oil chlorosulfonated polyethylene (CSM) hose is mainly used in the automotive industry. The CSM rubber hose is manufactured by extrusion process, the inner and outer layers are made of CSM rubber, and the middle reinforcement layer is aramid braided wire. It ...
