Abstract

The invention discloses a rubber sheath for an automobile universal joint. The rubber sheath comprises the following raw materials in parts by weight: 96-100 parts of neoprene S40V, 0.6-1 part of imarcaptoacetate dioctyltin, 1-2 parts of chlorine fluorine ethofenprox, 2-3 parts of beta-hydroxyalkylamide, 6-8 parts of anhydrous calcium chloride, 6-8 parts of triethyl acetocitrate, 1-2 parts of iron oxide red, 2-3 parts of glycerol triacetate, 1-2 parts of sodium sulfide, 10-14 parts of coal ash, 3-5 parts of calcium stearate, 1-2 parts of 2,6-Di-tert-butyl-4-methylphenol, 1-2 parts of an accelerating agent CZ, 0.8-1.2 parts of sulphur and 16-20 parts of a composite filler. The rubber sheath for the automobile universal joint, provided by the invention, has the effects of vibration reduction and sound insulation, and is good in water proofing and oil resistance, strong in abrasion resistance and excellent in comprehensive performance.

Description

technical field [0001] The invention mainly relates to the field of auto parts, in particular to a rubber sheath for an auto universal joint. Background technique [0002] Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. The disadvantage is poor cold resistance and storage stability. It has high tensile strength, elongation and reversible crystallinity, and good adhesion. Aging resistance and heat resistance. Excellent oil and chemical resistance. Weather resistance and ozone aging resistance are second only to ethylene propylene rubber and butyl rubber. The heat resistance is equivalent to that of nitrile rubber, the decomposition temperature is 230-260°C, the short-term resistance is 120-150°C, and it can be used for a long time at 80-100°C. It has certain flame retardancy. Oil resistance is second only to nitr...
