Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an environmentally friendly plastic pipe and a preparation method thereof. Background technique [0002] Plastic pipe is a chemical building material with high performance and added value. It is the fourth largest new type of building material after steel, wood and cement. 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 construction pipe networks in the new century. [0003] At present, common plastic pipes are produced by using PVC resin as the main material and adding some auxiliary materials. However, due to the incomplete reaction of PVC resin in the polymerization process, the residual vinyl chloride monomer i...
