Abstract

The invention discloses a cold-resistant anti-freezing power protection pipe which is characterized by being prepared from the following raw materials in parts by weight: 100-130 parts of polyvinyl chloride, 2-4 parts of magnesium hydroxide, 0.1-0.4 part of stearic acid, 6-10 parts of calcium carbonate, 0.2-0.5 part of sodium lignosulfonate, 1-2 parts of nano antimony trioxide, 0.5-1 part of sodium oleate, 0.4-1 part of a silane coupling agent kh550, 0.5-1 part of aluminum hydroxide, 1-3 parts of a Ca-Zn composite stabilizer, 0.5-1 part of a lemon essential oil, 1-3 parts of methacrylate, 1-2 parts of sulphur, and a proper amount of water. The PVC pipe adopts the reasonable ratio; the prepared PVC is excellent in performance, enhances the toughness and the strength while improving cold resistance and freezing resistance, greatly reduces the damage sensitivity, is not easy to damage, prolongs the service life, and has the advantage of being excellent in processing performance, non-toxic, small in dust pollution, low in cost, good in stability, simple in operation, and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of power protection tubes, in particular to a cold and frost-resistant power protection tube. Background technique [0002] PVC pipe has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes. It has excellent corrosion resistance and the cheapest price among all kinds of plastic pipes. 100°C, excellent chemical resistance, used for residential life, industrial and mining, agricultural water supply and drainage, irrigation, gas supply, exhaust pipes, wire conduits, rainwater pipes, industrial anti-corrosion pipes, etc. The main component of PVC is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. Compared with advanced countries, the production and application of plastic pipes in my country is not small, and many applications still need to be developed, waiting for us to develop, such as the development o...
