Abstract

The invention discloses a corrosion-resistant and high-temperature-resistant PVC-C pipe and a preparation method thereof. The corrosion-resistant high-temperature-resistant PVC-C pipe is prepared fromthe following raw materials in parts by weight: 100 parts of chlorinated polyvinyl chloride, 4 to 12 parts of acrylonitrile-butadiene-styrene copolymer, 12 to 20 parts of modified filler, 0.2 to 1.2parts of carbon black, 1.5 to 6.5 parts of silicon dioxide, 0.5 to 2.5 parts of stearic acid, 1 to 5 parts of dioctyl adipate, 2.8 to 8.5 parts of stable system and 0.8 to 2.6 parts of antioxidant. The corrosion-resistant and high-temperature-resistant PVC-C pipe prepared by the invention has the advantages of high Vicat softening temperature, excellent thermal aging resistance and high corrosionresistance and can be widely applied to the field with high comprehensive requirements, the preparation process is simple and feasible, and the corrosion-resistant and high-temperature-resistant PVC-Cpipe is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a corrosion-resistant and high-temperature resistant PVC-C pipe and a preparation method thereof. Background technique [0002] PVC-C, also known as chlorinated polyvinyl chloride (CPVC), is made by chlorination and modification of polyvinyl chloride resin. It is a new type of engineering plastic. After chlorination of PVC resin, the irregularity of molecular bonds increases, and the polarity Increase, the solubility of the resin increases, the chemical stability increases, thereby improving the heat resistance of the material, corrosion resistance to acids, alkalis, salts, oxidants, etc., and improving the mechanical properties of the heat distortion temperature of the resin. CPVC is mainly used to produce plates, rods, and pipes to convey hot water and corrosive media. With the rapid development of the industry, the corrosion resistance and high temperature resistance...
