Chloroprene rubber sheath and preparation method thereof

Abstract

The invention discloses a chloroprene rubber sheath and a preparation method of the chloroprene rubber sheath, according to the parts by weight of raw materials, chloroprene rubber is cut and is then uniformly blended with magnesium oxide, zinc oxide, titanium white, stearic acid, microcrystalline wax, antimonous oxide, aluminium hydroxide, silicon metal powder, white carbon black, superfine talcum powder, antioxygen 7910, antioxygen 264, accelerating agent DM and coloring agent, then one kneading is performed, an open mill 400 and an open mill 300 are respectively started, silane coupling agent A-172 and accelerating agent NA-22 are added into the mixture, then the second kneading is performed, the open mill 400 and the open mill 300 are started, and finally, a finished product is obtained after lamination and rubber discharge are completed. Various chemical materials are used to make the chloroprene rubber sheath, therefore, the chloroprene rubber sheath has excellent high-temperature resistance and heat-resistance performances, strong compression performance and rigidity and good flame retardant property, the preparation cost is low, and the process is simple.

Description

technical field [0001] The invention relates to a neoprene sheath and a preparation method thereof, belonging to the field of cable materials. Background technique [0002] A large number of fire reports have confirmed that the culprit of human death is the smoke and toxic gases generated when plastics burn, especially for high-rise buildings. According to statistics, 80% of the deaths in fires are due to suffocation of smoke and toxic gases. Caused. Since polyvinyl chloride, polyethylene, polypropylene, polystyrene and ABS are collectively referred to as the five general-purpose resins, they are the first in my country and the second in the world for general-purpose synthetic resin materials, and are widely used in various building materials and daily necessities, etc. aspect. Therefore, it has become one of the key research topics in the field of flame-retardant plastics in recent years to reduce the amount of smoke and toxic gases generated when plastics are burned.

Problems solved by technology

[0003] The main use of chlorinated polyethylene at home and abroad is to make cables. The existing chlorinated polyethylene sheathed wires and cables are quite polluted, and will produce a large amount of harmful substances such as dioxin, hydrochloric acid, and lead. There will be a lot of thick smoke and harmful HCL gas, which will cause certain harm to human health; after incineration or burial, it will cause pollution to soil and water sources
