Problems solved by technology

[0002] On the one hand, buried pipes used as power sheathing must face the effects of stratum subsidence, earthquakes or extrusion from external loads, and on the other hand, they must withstand the lower temperature of the stratum, stratum subsidence, earthquakes, or extrusion from external loads. When the pressure is severe, the sheath pipe will be broken, the inner line will be damaged, and the power supply of the circuit will fail. However, ordinary plastic pipes are heat-sensitive materials, which are brittle and brittle below zero. Pressed like fragile glass, it needs to be modified

Abstract

The invention provides an anti-settlement electric power protecting pipe with ultra toughness and low temperature resistance characteristics, and the product is prepared by the following components by weight ratio: 100 parts of three-type PVC resin, 3-5 parts of stabilizing agents, 2-4 parts of antishock type acrylic acid ester, 3-5 parts of chlorinated polyethylene, 8-15 parts of modified rubber, 1-2 parts of lubricants, 3-5 parts of processing auxiliary agents and 0-5 parts of masterbatch. The 100 parts of three type PVC resin are used as a main material, antishock type acrylic acid ester and modified rubber and a plurality of antishock modified material are cooperative for toughness modification, and pipeline products produced by the die has the following characteristics: 1. good toughness with fracture percentage elongation which is more than 350; 2. good rigidity, which is obviously higher than common polyolefin tubings; 3. high recovery rate which is above 70%; 4. strong acid and alkali resistance capability, which has little soda acid influence to underground environment with environmental protection and without pollution because the components do not have inorganic filling materials; 5. the inner and outer surface are slide with small friction resistance; 6. the aging resistance performance is good.

Description

technical field [0001] The invention belongs to the technical field of electric power sheath pipes, in particular to an electric power sheath pipe which is resistant to subsidence and has super toughness and low temperature resistance. Background technique [0002] On the one hand, buried pipes used as power sheathing must face the effects of stratum subsidence, earthquakes or extrusion from external loads, and on the other hand, they must withstand the lower temperature of the stratum, stratum settlement, earthquakes, or extrusion from external loads. When the pressure is severe, the sheath pipe will be broken, the inner line will be damaged, and the power supply of the circuit will fail. However, ordinary plastic pipes are heat-sensitive materials, which are brittle and brittle below zero, especially at minus 15°C in the north. Pressed like fragile glass, it needs to be modified. Contents of the invention [0003] The invention mainly solves the technical problems exist...
