Abstract

The invention discloses a PVC cable sheath for wrapping a thermoplastic elastomer. The PVC cable sheath is prepared from 100g of POC, 0.14g of an antioxidant, 6g of TIS, 10-20g of DOP, 1g of DIS, 6-9g of C-P52 / T-50, 0.5g of PBST, 40-50g of activated calcium carbonate, 13g of other additives and 0.4g of paraffin. The PVC cable sheath disclosed by the invention is good in high temperature resistance and aging resistance, is applicable to high temperature caused by overload short circuit generated when an electric cable is used, is high in insulating strength and volume electrical resistivity, good in flexibility, high in pressure resistance and differential settlement resistance, does not need to be coated by placing concrete in a construction field, and is small in inner wall surface friction coefficient, beneficial to use and long in service life.

Description

technical field [0001] The invention relates to a cable sleeve, in particular to a PVC cable sheath wrapped with a thermoplastic elastomer. 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 deficienc...
