Abstract

The invention discloses a cable sheath material capable of resisting a temperature of 150 DEG C and being used for a bullet train with a nominal voltage of 3,600 V, and a preparation method thereof. The cable sheath material is prepared from the following raw materials by weight: 70-90 parts of phenylatylene silicone rubber, 25-45 parts of chloroprene rubber, 3-5 parts of titanium(diisopropoxide)bis(2,4-pentanedionate), 2-4 parts of dicumyl peroxide, 1.5-2.5 parts of tert-butyl peroxybenzoate, 2-4 parts of trimethylolpropane trimethacrylate, 15-25 parts of carbon black N660, 10-15 parts of tris(2,3-dibromopropyl)isocyanurate, 5-10 parts of spindle oil, 6-12 parts of hydrogenated rosin glycerol ester, 5-10 parts of boron carbide, 12-16 parts of glass powder, 4-6 parts of nano bismuth oxide, 2-4 parts of nano beta zeolite, 16-22 parts of organic bentonite, 5-10 parts of stone needle powder, 10-15 parts of aluminium hypophosphite, 3-6 parts of nickel molybdate, 8-14 parts of modified stone powder, 2-3 parts of 4,4'-dithiodimorpholine, 1-2 parts of polycarbodiimide and 2-3 parts of styrenated phenol. The cable sheath material provided by the invention has excellent electrical insulation property and high temperature resistance; a voltage class reaches 3,600 KV; a high temperature resistance level reaches 150 DEG C; and the cable sheath material can keep good physical and mechanical properties at high voltage and high temperature.

Description

technical field [0001] The invention relates to a 150°C resistant cable sheath material for a motor vehicle with a rated voltage of 3600V and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] In recent years, with the rapid development of national rail transit, the control of motor train units and high-speed units has become more and more complex, and there are more and more electrical control equipment, the demand for cables will inevitably increase accordingly, and the performance requirements for cable materials will also increase. getting stricter. At present, there are few sheathing materials for motor vehicle cables that can meet the rated voltage of 3600V and withstand 150°C, which cannot meet the market demand for motor vehicle cables. Therefore, it is urgent to change the formula of traditional cable materials and develop a rated voltage of 3600V for motor vehicles. 150°C resistant cable sheathing material to mee...
