Abstract

Belonging to the technical field of building pipelines, the invention relates to an environment-friendly and lead-free PVC water supply pipeline material, which comprises the following components by mass: 100 parts of PVC-5; 0.5-1 part of 181 methyltin; 6-12 parts of nano-calcium; 1-4 parts of ACR1; 1-3 parts of MBS; 1-3 parts of rutile titanium dioxide ; 0.1-1.0 part of PE wax; and 0.1-1.0 part of glyceryl monostearate. The environment-friendly and lead-free PVC water supply pipeline material provided by the invention has reasonable compatibility, and can be made into high strength, high toughness and lead-free water supply pipelines.

Description

technical field [0001] The invention belongs to the technical field of building pipes, and relates to a plastic pipe, in particular to a lead-free PVC pipe material. Background technique [0002] The water supply pipeline is made of sanitary polyvinyl chloride (PVC) resin as the main raw material, adding an appropriate amount of stabilizer, lubricant, filler, color enhancer, etc., extruded by a plastic extruder and injected by an injection molding machine, and cooled and solidified , shaping, testing, packaging and other processes to complete the production of pipes and fittings. [0003] With the development of science and technology and the improvement of people's living standards, "health" and "safety" have become the two most concerned themes of modern people. The quality of drinking water and the safety of water pipes have naturally become one of the focuses of attention. Lead in PVC pipes is a health hazard. my country's PVC pipes have developed rapidly in recent ye...
