Embodiment 1

[0007] The ingredients used are: neoprene, vulcanization accelerator, activator, anti-scorch agent, anti-aging agent, reinforcing agent, softener, filler. Key points when formulating: choose W-type neoprene rubber with good thermal stability as the base material; increase the amount of vulcanizing agent (zinc oxide), use no magnesium oxide, and use accelerator DM as an anti-scorch agent; use accelerator NA222 to increase chlorine The vulcanization speed and degree of vulcanization of butyl rubber; use oil with high critical temperature, low volatility, high molecular weight, and high saturation as softener, and use several softeners together; use inorganic compounding agent light CaCO3 as the main filler; use heat-resistant Anti-aging agent with excellent performance, such as Kg2405 or DBTU, etc. All W-type glues of the present embodiment are compared with general-purpose glues:

Abstract

The invention discloses a novel heatproof chloroprene rubber cable sleeve. The formula of the cable sleeve comprises chloroprene rubber, a vulcanization accelerator, an activator, an anti-scorching agent, an antioxidant, a strengthening agent, a softener and a filler. With the development of the electric wire and cable industry, people put forward higher and more stringent performance requirements of wire and cable products. The chloroprene rubber is synthetic rubber with good heatproof property, is close to natural rubber in performances, and also has the advantages of heatproof property, oil resistance, weather ageing resistance, flame retardation and chemical corrosion resistance lacked by the natural rubber, so the chloroprene rubber is called as multifunctional rubber.

Description

technical field [0001] The invention relates to the field of polymers, in particular to a novel heat-resistant neoprene cable sheath. Background technique [0002] With the development of the wire and cable industry, people put forward higher and stricter performance requirements for cable products. For example, when my country's ocean-going research ships sailing to the Antarctic pass near the equator, the cables on the ship have to withstand the high temperature test of seventy to eighty degrees; Another example is that cables used in mines work in the harsh underground environment, which must be flame retardant and withstand temperature changes. Therefore, drastic changes in temperature are severe tests for materials. At a certain high temperature, the performance of cable materials will change in one way or another, and some will even lose their use value. Therefore, if rubber is used as an insulation or sheath material, if it does not have a certain heat resistance, ...
