Abstract

The invention discloses a black PVC cable sheath sleeve resisting 70 DEG C. The formula comprises the following ingredients: 75 g of PVC three-form powder, 45 g of activated carbon, 45 g of DINP (Diisononyl Phthalate), 3 g of soybean oil, 20 g of chlorinated paraffin, 2.8 g of a stabilizer, 0.6 g of stearic acid, 9 g of CPE (Chlorinated Polyethylene), and 1 g of paraffin. The product disclosed by the invention is good in high temperature resistance and ageing resistance, and can be adapted to the high temperature caused by overload short circuit in the power cable using process; the materials are high in insulating strength and high in volume resistivity; the product is good in flexibility, high in compressive strength, and differential settlement resistant; the concrete is not required to be encapsulated at a construction site; the high-elasticity synthesized PVC cable sheath is low in inner wall surface friction coefficient, beneficial to application, and long in service life.

Description

technical field [0001] The invention relates to a cable casing, in particular to a black 70°C PVC cable sheathing material. 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 the prior...
