Abstract

The invention discloses an environment-friendly PVC cable protection sleeve which is prepared from the following raw materials: 70-80 percent of polyvinyl chloride resin, 5-10 percent of a heat stabilizer, 2-5 percent of a light stabilizer, 3-5 percent of an antioxidant, 2-5 percent of an auxiliary stabilizer, 1-2 percent of a plasticizer, 1-2 percent of a coloring agent, 1-2 percent of a lubricating agent, 1-2 percent of an impact modifier and 1-2 percent of other auxiliaries. The environment-friendly PVC cable protection sleeve is good in high-temperature resistance and high in aging resistance and can adapt to high temperature generated by overload short circuit in the using process of a power cable; the materials are high in insulating strength and high in volume resistivity, so that the environment-friendly PVC cable protection sleeve is high in flexibility and high in tensile strength, can resist uneven settlement, and is not required to be wrapped with concrete on the construction site; the friction coefficient of the surface of the inner wall is small, so that the use is facilitated, and the service life of the environment-friendly PVC cable protection sleeve is long.

Description

technical field [0001] The invention relates to a cable casing, in particular to an environment-friendly PVC cable protection casing. Background technique [0002] At present, the cable casing for engineering is made of polyvinyl chloride resin as the main material, heavy calcium carbonate as the filler, and chlorinated polyethylene, paraffin and other small materials, and has certain corrosion resistance, high temperature resistance, flame retardancy, Insulation, wear resistance, light weight, no pollution and other characteristics. However, its shortcomings are poor compressive strength, which is still far behind the requirements of construction and application, and its flame retardant performance is not ideal; in addition, its Vicat softening temperature hovers around 90°C, and the friction coefficient of inner and outer pipe walls is large, which increases the construction efficiency. Difficulty of use. Contents of the invention [0003] Aiming at the deficiencies in...
