Example Embodiment

[0014] Example 1

[0015] An automobile motor wiring harness rubber sheath is composed of the following raw materials in parts by weight (kg):

[0016] Neoprene S40V 100, polyvinyl ether 8, locust bean gum 3, ferrous sulfate 1, PTFE wax 4, bone charcoal 18, tetrabutylammonium bromide 0.4, sodium fluorosilicate 2, precipitated silica 13 , antioxidant DFC-342, sulfur 0.7, sodium peroxide 0.2, chlorinated paraffin 7, antioxidant 168 2, composite filler 20;

[0017] Described composite filler is made up of the following raw materials by weight:

[0018] Black soil 45, Wannian ash 6, fly ash 13, soda powder 2, bisimidazolidinyl urea 1, hexamethoxymethyl melamine resin 2, appropriate amount of water;

[0019] Add the above-mentioned soda powder into 2 times of water, stir evenly, add Wannian ash, heat and stir at 50 ° C until the water is dry, add hexamethoxymethyl melamine resin, stir and disperse at 300 rpm for 5 minutes to obtain a premix; The above-mentioned black soil and fl...

Abstract

The invention discloses an automobile motor wire harness rubber sheath. The automobile motor wire harness rubber sheath is prepared from following raw materials, by weight, 95 to 100 parts of chloroprene rubber S40V, 6 to 8 parts of polyvinyl ether, 3 to 4 parts of locust bean gum, 1 to 2 parts of ferrous sulphate, 4 to 6 parts of teflon wax, 12 to 18 parts of bone black, 0.2 to 0.4 part of tetrabutylammonium bromide, 1 to 2 parts sodium fluosilicate, 10 to 13 parts of Precipitated white carbon black, 1 to 2 parts of anti-aging agent DFC-34, 0.7 to 1 part of sulphur, 0.1 to 0.2 part of sodium peroxide, 7 to 8 parts of chlorinated paraffin, 1 to 2 parts of anti-oxidant 168, and 14 to 20 parts of a composite filling material. The automobile motor wire harness rubber sheath is capable of preventing motor from mud and water mixture, and avoiding motor short circuit and fire failure; can be installed firmly; is not easy to fall off or break; and is high in strength, and rebound resilience.

Description

technical field [0001] The invention mainly relates to the field of auto parts, in particular to a rubber sheath of an automobile motor wiring harness. 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 resistance. The disadvantage is poor cold resistance and storage stability. Has high tensile strength, elongation and reversible crystallinity, good adhesion. Aging resistance, 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 comparable to that of nitrile rubber, the decomposition temperature is 230-260°C, the short-term resistance is 120-150°C, and the long-term use at 80-100°C has a certain flame retardancy. Oil resistance is second only to nitrile rubber. Good resis...
