Abstract

The invention relates to a highly impact-resistant PVC tube and a production method thereof. The highly impact-resistant PVC tube is characterized by comprising the following raw materials in parts byweight: 80-100 parts of a polyvinyl chloride resin, 10-20 parts of nano anhydrous calcium sulfate, 5-10 parts of an impact resistance modifier, 2-6 parts of a composite stabilizer, 1-3 parts of PE (Polyethylene) wax, 1-3 parts of titanium dioxide, 0.5-2 parts of a silane coupling agent and 0.2-0.5 part of a composite antioxidant. The highly impact-resistant PVC tube is simple and easy in raw material obtaining, low in cost, very good in impact resistance, flexibility and low temperature resistance, and the added impact resistance modifier is very good in compatibility with a PVC resin, good in dispersibility, simple in preparation method and capable of greatly improving the impact resistance of PVC tubes.

Description

technical field [0001] The invention belongs to the processing field of PVC pipes, and in particular relates to a high impact-resistant PVC pipe and a production method thereof. Background technique [0002] Plastic pipes are high-tech composite chemical building materials, and chemical building materials are the fourth largest category of new building materials emerging in the contemporary era after steel, wood, and cement. Chemical building materials have made great progress and developed rapidly in our 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 such as small water loss, energy saving, material saving, ecological protection, and convenient completion. They have become the main force of urban constructio...
