Abstract

The invention discloses an anti-aging flame-retardant pipeline material which comprises the following components in parts by weight: 100-150 parts of polyvinyl chloride resin; 50 to 70 parts of nano modified master batch; 8 to 12 parts of nano aluminum oxide; 12 to 15 parts of maleic anhydride grafted polyethylene; 5 to 15 parts of nano modified carbon black; wherein the nano modified master batch is prepared by stirring and mixing polyethylene glycol terephthalate, nano light calcium carbonate, a nanofiber nucleating agent and color master batch at a high speed; the polyethylene glycol terephthalate, the nano light calcium carbonate, the nano fiber nucleating agent and the color master batch comprise the following components in parts by weight: 60 parts of poly (ethylene terephthalate); 10 to 20 parts of nano light calcium carbonate; 2-3 parts of a nanofiber nucleating agent; and 4-5 parts of color master batch. The invention also discloses a preparation method of the anti-aging flame-retardant pipeline material, and the anti-aging flame-retardant pipeline material prepared by the method can improve the anti-aging capability of a pipeline and improve the flame retardance of the pipeline.

Description

technical field [0001] The invention relates to the technical field of plastic drainage pipes, in particular to an anti-aging and flame-retardant pipe material and a preparation method thereof. Background technique [0002] At present, only polyvinyl chloride (PVC) pipes are used for drainage pipes, but they have defects such as poor anti-aging and weather resistance, toxicity, poor toughness, poor heat resistance, and non-abrasion resistance. With the development of science and technology and the improvement of people's living standards, "health" and "safety" have become the two most critical issues for modern people. Therefore, the development of high-performance, green and environmentally friendly plastic pipes is the development goal of the plastic pipe industry, and it is increasingly concerned by modern people who pursue healthy and fashionable life. [0003] At present, the main direction of plastic pipe technology innovation in the world is: through material modific...
