Abstract

The invention relates to the technical field of plastic pipes, and in particular relates to a super-tough and super-flexible high-temperature-resistance polyvinyl chloride pipe and a manufacturing technology thereof. The super-tough and super-flexible high-temperature-resistance polyvinyl chloride pipe comprises the following components in parts by weight: 50-65 parts of polyvinyl chloride, 25-38 parts of chlorinated polyvinyl chloride, 12-18 parts of shock resistance agent, 4-10 parts of filler, 3-8 parts of stabilizing agent, 2-5 parts of plasticizer, 0.1-0.6 part of external lubricating agent, 0.1-0.6 part of internal lubricating agent and 3-7 parts of modifying agent. The pipe has the advantages of high intensity, high super-flexibility, high-temperature resistance, shock resistance, corrosion resistance and lower cost and can meet a construction requirement on an electronic pipe.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a super-strong, super-tough, high-temperature-resistant polyvinyl chloride pipe and a preparation process thereof. Background technique [0002] With the country's vigorous development of the power industry, more and more plastic power pipes are used in the market, especially in the laying method of excavated power pipelines, most of which are polyvinyl chloride power pipes. Compared with polyethylene power pipes, polyvinyl chloride has better strength and impact resistance due to its larger elastic modulus. Compared with PP pipes, polyvinyl chloride has better resistance to low temperature brittleness and compressive strength. Although some properties of chlorinated polyvinyl chloride are superior to those of polyvinyl chloride, since the cost of chlorinated polyvinyl chloride is much higher than that of polyvinyl chloride, polyvinyl chloride has great potential in power p...
