Abstract
The invention provides an ethylene-propylene-diene rubber thermal shrinkable tube to solve the problem that the conventional thermal shrinkable tube has low performance in the aspects of high-temperature resistance, oil resistance and solvent resistance and cannot meet the performance requirements of the industries such as automobiles, high-speed trains, military projects and aerospace on high oil resistance and high solvent resistance. The ethylene-propylene-diene rubber thermal shrinkable tube is made from the following materials: ethylene-propylene-diene rubber, thermal shrinkable resin and a reinforcing agent. The zinc oxide, zinc stearate, a softener and an age resister can be added selectively. When chemical crosslinking is adopted, a crosslinker is required. Meanwhile, the invention provides three methods for producing the thermal shrinkable tubes from the materials, namely a two-step mixing electronic crosslinking method, a one-step mixing electronic crosslinking method and a chemical crosslinking method. The ethylene-propylene-diene rubber thermal shrinkable tube provided by the invention has high ozone resistance, weather-aging resistance, high heat resistance, high vapor resistance, high electric insulation and high chemical medium resistance and can be applied in the connector protection and sealing of power supply lines.
