Abstract

The invention discloses a high-temperature-resistant polyvinyl chloride pipe, which is prepared from the following raw materials in parts by weight: 40-50 parts of polyvinyl chloride, 15-24 parts of methyl vinyl silicone rubber, 1-2 parts of 1, 3-bis (tert-butyl peroxy isopropyl) benzene, 0.2-0.8 part of N-cyclohexyl-2-benzothiazolesulfenamide, 1-2 parts of zinc oxide, 40-50 parts of a filling reinforcing agent, 1-3 parts of magnesium oxide, 1-2 parts of carboxymethyl cellulose, 1-3 parts of an anti-aging agent, 1-2 parts of poly-metaphosphoric acid and 3-6 parts of a plasticizer. The high-temperature-resistant polyvinyl chloride pipe provided by the invention has high temperature aging resistance, thus being used for a long time at the temperature of 230 DEG C and better maintaining the physical properties at the temperature of 280 DEG C; the high-temperature-resistant polyvinyl chloride pipe has ultra-low compression permanent deformation, thus achieving the effect of effective sealing in a using process.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride, in particular to a high-temperature-resistant polyvinyl chloride pipe. Background technique [0002] PVC is the abbreviation of Polyvinylchlorid. The main component of PVC pipe is polyvinyl chloride, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. A material. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. At present, the high temperature resistance of PVC pipes cannot meet the demand, and the sealing performance needs to be improved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a high-temperature-resistant polyvinyl chloride pipe, which has high-temperature aging resistance, can be used for a long time at 230°C, and can maintain good physical proper...
