Abstract

The invention relates to a formula of a high-toughness polyvinyl chloride (PVC) pipe, and belongs to the technical field of pipes. The PVC pipe comprises the following components in parts by weight: 100 parts of PVC resin, 1.0-2.0 parts of an organic tin stabilizer, 1.0-2.0 parts of a composite anti-aging agent, 1.5-2.5 parts of paraffin, 5.0-10.0 parts of filler, 3.0-6.0 parts of a processing aid, 1.0-3.0 parts of ethylene-vinyl acetate (EVA) and 3.0-6.0 parts of a plasticizer. The PVC pipe produced by the method reserves a high impact strength value and has good toughness at the same time.

Description

technical field [0001] The invention relates to a formula of high-toughness PVC pipes, belonging to the technical field of pipes. Background technique [0002] Polyvinyl chloride, referred to as PVC, is the first in China and the second largest general-purpose synthetic resin material in the world. Due to its excellent flame retardancy, wear resistance, chemical corrosion resistance, comprehensive mechanical properties, product transparency, and electrical insulation And relatively easy to process, etc. At present, PVC has become one of the most widely used plastic varieties. It is widely used in industry, construction, agriculture, daily life, packaging, electric power, public utilities and other fields. PVC is a A non-toxic, odorless white powder. It has high chemical stability and good plasticity. Except for a few organic solvents, it can withstand any concentration of hydrochloric acid, [0003] Less than 90% of sulfuric acid, 50-60% of nitric acid and less than 20% o...
