Abstract

The invention relates to PVC-U pipes, and belongs to the technical field of pipes. The PVC-U pipes are prepared from the following raw materials in parts by weight: 60 parts of butadiene-acrylonitrilerubber, 20 parts of ethylene-propylene rubber, 10 parts of chlorinated polyvinylchloride, 1.0-2.0 parts of an organic tin stablizer, 7.0-14.0 parts of carbon nano-tubes, 1.0-1.5 parts of an anti-aging agent, 2.0-3.0 parts of a lubricant, 5.0-10.0 parts of a filling agent, 3.0-6.0 parts of EVA, and 5.0-8.0 parts of a compound plasticizer. The PVC-U pipes produced according to the invention preserve relatively high impact strength values, and have relatively good tenacity.

Description

technical field [0001] The invention relates to a formula for PVC-U pipes, belonging to the technical field of pipes. Background technique [0002] PVC material is polyvinyl chloride. It is one of the largest plastic products in the world. It is cheap and widely used. Due to its high chemical stability, it can be used to make anti-corrosion pipes, pipe fittings, oil pipelines, centrifugal pumps and blowers. Polyvinyl chloride hard board is widely used in the chemical industry to make various storage tank linings, corrugated boards for buildings, door and window structures, wall decorations and other building materials. Due to its excellent electrical insulation properties, it can be used in the manufacture of plugs, sockets, switches and cables in the electrical and electronic industries. In everyday life, PVC is used in the manufacture of sandals, raincoats, toys, artificial leather and more! It can be seen that PVC-U pipes are widely used, but with the continuous develop...
