Abstract

The invention discloses a formula and a making method of a plastic tube. The formula comprises 80-120 parts of PVC resin, 8-20 parts of a filler, 4-12 parts of a flexibilizer, 1-6 parts of a compositestabilizer, 0.5-2 parts of ACR, 0.1-0.5 part of a lubricant and 0.01-0.1 part of a colorizing agent. The addition of MBS and ACR to the formula of the plastic tube remarkably improves the strength and the toughness of the plastic tube and enhances the strength and the toughness of the plastic tube; the composite stabilizer is a liquid calcium-zinc composite stabilizer, contains no lead element, and reduces environment pollution generated by burying; and the plastic tube has the advantages of reasonable formula, high strength, good toughness, small environmental pollution, and realization of wide promotion and application.

Description

【Technical field】 [0001] The present invention relates to the technical field of pipes, in particular to the technical field of plastic pipes. 【Background technique】 [0002] Plastic pipes are high-tech composite chemical building materials, and chemical building materials are the fourth new type of building materials emerging today after steel, wood and cement. In recent years, chemical building materials have made great progress and rapid development in my country, especially the widespread use of new environmentally friendly plastic pipes, which has set off a revolution to replace traditional building materials. Plastic pipes are widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes because of their advantages of small water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban construction pipe network in the new century. [0003] However,...
