Abstract

The invention discloses an automobile backdoor wire harness fixing rubber sheath. The automobile backdoor wire harness fixing rubber sheath is prepared from following raw materials, by weight, 94 to 100 parts of chloroprene rubber S40V, 7 to 10 parts of superfine barium sulfate, 1 to 2 parts of aluminium triphosphate, 1 to 2 parts of molybdenum boride, 4 to 6 parts of tailing, 0.4 to 1 part of Potassium Perfluorobutanesulfonate, 2 to 3 parts of diammonium tetraborate, 2 to 3 parts of polyisoprene, 3 to 5 parts of acrylate levelling agent, 5 to 7 parts of epoxidized soybean oil, 1 to 2 parts of ammonium dihydrogen phosphate, 1 to 2 parts of anti-aging agent RD, 1 to 1.3 parts of sulphur, 2 to 3 parts of Hydrated zinc borate, 1 to 2 parts of promoter CA, and 20 to 25 parts of a composite filling material. The automobile backdoor wire harness fixing rubber sheath possesses dust prevention effect, water resistance, wear resistance, and excellent protective effect; can be installed firmly; is not easy to fall off or break; and is easy to bend; and friction with wire harness is small.

Description

technical field [0001] The invention mainly relates to the field of auto parts, in particular to a rubber protective cover for fixing the wire harness of the back door of an automobile. 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 retard...
