Abstract

The invention discloses a formula of multi-walled PVC for a communication pipe. The multi-walled PVC is prepared from 60 to 100 parts by weight of PVC resin, 4 to 7 parts by weight of calcium stearate, 2 to 7 parts by weight of dioctyl picaprate, 1 to 3 parts by weight of styrene-butadiene rubber, 2 to 8 parts by weight of a lubricant, 0.5 to 3 parts by weight of PE wax, 6 to 8 parts by weight of hexamethylphosphoric triamide, 1 to 2 parts by weight of a rare earth stabilizer, 2 to 3 parts by weight of polyethylene wax and 0.5 to 1.3 parts by weight of an auxiliary agent. The multi-walled PVC is prepared from the PVC resin as the main raw material. Through high temperature and high pressure extrusion molding, the impact resistance, the high temperature resistance, the cold resistance and the long service life are obtained. The multi-walled PVC is used for laying an underground communication pipe, can protect a communication optical cable and cable, realizes a low cost and is suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a multi-wall PVC formula for communication pipes. Background technique [0002] The main component of PVC pipe is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. PVC is well-loved in the world today and is a popular and widely used synthetic material. PVC pipe is a mature pipe, mainly used in water supply and drainage projects. PVC pipe has the advantages of acid resistance, alkali resistance, corrosion resistance and high strength, but its impact resistance is relatively poor. Contents of the invention [0003] The invention provides a multi-wall PVC formula for communication pipelines, and the PVC pipes manufactured by using the formula can enhance the impact resistance and strength. [0004] In order to achieve the above object, the present invention is a multi-wall PVC formulation for communication pip...
