Abstract

The invention relates to a chlorosulfonated polyethylene lead-free recipe for a power steering pipe. The recipe contains the following components: 100 parts of chlorosulfonated polyethylene rubber (CSM), 30-50 parts of fast extruding furnace black (N550), 15-35 parts of softener T810T, 5-20 parts of dioctyl sebacate (DOS), 10-20 parts of light calcium carbonate, 0.5-2 parts of flow promotor WS1 80, 0.5-2 parts of flow promotor WA 48, 0.5-2 parts of antiager NDBC, 0.5-3 parts of N'N-m-phenylene dimaleimide (HVA-2), 0.5-2 parts of dipentamethylenethiuram tetrasulfide (DPTT) and 0.5-1 part of dibenzothiazyl disulfide DM. The recipe has the characteristics of high strength, high hardness, low compression residual deformation, oil resistance and the like, thereby completely meeting the demands of the power steering pipes; meanwhile, the recipe has no toxin or odor and is stable in storage.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a lead-free formulation of chlorosulfonated polyethylene for power steering hoses. Background technique [0002] The facts and challenges facing the automotive industry are based on the premise of protecting the environment. The global environmental protection regulations mainly focus on the use of the following substances: mercury, lead, chromium, cadmium, etc. The power steering system of a modern car is basically a hydraulic system, and the power steering system used by the car is a modified manual steering system. The main thing is to add a power booster (PowerBooster) to help the driver. However, the power steering tube connecting the booster and the steering wheel not only needs to have strong bending force, aging resistance, ozone resistance, and power steering hydraulic oil resistance, but also should be environmentally friendly and pollution-free. [0003] In the p...
