Problems solved by technology

As a prominent problem of power pipes is heat resistance, so chlorinated polyvinyl chloride (CPVC) power pipes with heat resistance have appeared, which are currently used as the main raw material of chlorinated polyvinyl chloride (CPVC) power pipes. The special resin for ethylene power tubes is expensive, which restricts the development of plastic power tubes, and the problem of high cost needs to be solved urgently

Embodiment Construction

[0006] specific implementation plan

[0007] The parts by weight of the basic materials of a new type of power tube are: 40 parts of SAN resin, 30 parts of chlorinated polyvinyl chloride resin, 30 parts of polyvinyl chloride, 6 parts of stabilizer, 2 parts of lubricant, 4 parts of impact modifier, 10 parts of talcum powder, 0.4 parts of pigment.

[0008] A kind of novel power tube preparation process of the present invention is carried out according to the following procedures:

[0009] a) In parts by weight, mix SAN resin, chlorinated polyvinyl chloride resin, polyvinyl chloride, stabilizer, lubricant, impact modifier, talcum powder, and pigment at 90-120°C, and Keep within the range for more than 10 minutes;

[0010] b) Put the above mixture into the cold mixer to cool down to 25-45°C, and import it into the drying silo;

[0011] c) The mixture in the drying silo is extruded by a conical twin-screw extruder, vacuum sized and cooled to form a pipe;

[0012] d) Cut to leng...

Abstract

The invention relates to a novel electric tube, which is made from the following basic materials in part by weight: 40 parts of SAN (Styrene-Acrylonitrile) resin, 30 parts of chlorinated polyvinyl chloride resin, 30 parts of polyvinyl chloride, 5-8 parts of stabilizing agents, 1-2 parts of lubricant, 3-5 parts of impact modifier, 8-15 parts of talcum powder and 0-0.5 part of pigment. Compared with the general metal tube, the novel electric tube has the advantages that: the corrosion resistance is more excellent, the heat resistance of the electric tube is further improved by adding the SAN resin, and the comprehensive cost is lower than that of resin special for a chlorinated polyvinyl chloride electric tube.

Description

technical field [0001] The invention relates to a plastic pipe, in particular to a new electric power pipe. Background technique [0002] The early power pipes mostly used metal pipes, which had poor corrosion resistance. With the development of technology, plastic power pipes began to replace metal pipes. As a prominent problem of power pipes is heat resistance, so chlorinated polyvinyl chloride (CPVC) power pipes with heat resistance have appeared, which are currently used as the main raw material of chlorinated polyvinyl chloride (CPVC) power pipes. The special resin for ethylene power tubes is expensive, which restricts the development of plastic power tubes, and the problem of high cost needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and propose a novel power tube. [0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows. A...
