Abstract

The invention discloses a chlorinated polyvinyl chloride pipe material and a preparation method thereof. The chlorinated polyvinyl chloride pipe material disclosed by the invention comprises the following components in parts by weight of: 100 parts of chlorinated polyvinyl chloride resin, 0.3-5 parts of stabilizer, 1-4 parts of lubricant, 1-3 parts of processing modification addition agent, 3-10 parts of anti-impact modification additive, 3-10 parts of fire retardant and 0.1-4 parts of paint. Compared with the ordinary chlorinated polyvinyl chloride pipe material, the high temperature resistance, the toughness and the anti-flaming and smoke abatement property of the chlorinated polyvinyl chloride pipe material disclosed by the invention can be greatly improved. The chlorinated polyvinyl chloride pipe material can be widely applicable to various fields with requirements on the high temperature resistance and the anti-flaming and smoke abatement property, such as industrial or civil architectures and municipal engineering.

Description

technical field [0001] The invention relates to the field of plastic pipes, in particular to a chlorinated polyvinyl chloride pipe and a preparation method thereof. Background technique [0002] In recent years, with the modernization of construction pipelines, plastic materials have developed rapidly in the domestic building material pipeline industry, but the existing PVC-U pipelines for water supply and drainage have limited their use due to defects such as heat resistance and dense smoke generated during combustion. Prospects for the development of the construction plumbing industry. [0003] Chlorinated polyvinyl chloride (CPVC) is a new type of engineering plastic obtained by chlorinating and modifying PVC resin. Because CPVC has the characteristics of excellent aging resistance, corrosion resistance and high flame retardancy, the tube sheet injection molded parts made of it are widely used in the construction industry, especially for the upper and lower water pipes o...
