Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a thermoplastic vulcanized rubber material for an automobile steering dust cover and a preparation method thereof. Background technique [0002] The main function of the automobile steering dust cover is to prevent dust, moisture, oil, mud, sand, etc. The impact requires that its manufacturing materials have high temperature resistance, ozone resistance, oil resistance and weather resistance, so the requirements for materials are also very important. Thermoplastic vulcanizate has good elasticity and compression deformation resistance, and its environmental resistance and aging resistance are equivalent to ethylene-propylene rubber. At the same time, its oil resistance and solvent resistance are comparable to general-purpose neoprene rubber. The thermoplastic vulcanized rubber body can be used in the temperature range of -60°C-135°C. The thermoplastic vulcanized rubber b...
