Abstract

The invention discloses a rigid polyvinyl chloride pipe material and a preparation method thereof, and relates to the field of high polymer materials. The rigid polyvinyl chloride pipe material provided by the invention comprises the following components in parts by weight: 100 parts of PVC resin; 1-6 parts by weight of a stabilizer; 1-6 parts by weight of an impact modifier; 10-40 parts by weightof a filler; 1-6 parts by weight of a processing aid; 1-3 parts by weight of a lubricant; 0.5 to 2 parts by weight of toner; and 2-6 parts by weight of silicone powder. The silicone powder with highsilica content and high molecular weight is added into the polyvinyl chloride resin, so that the polyvinyl chloride resin can be used as a wear-resistant agent, and thereby the friction coefficient between silicone is relatively small, the dispersity is uniform, the lubricating property is good, and the surface smoothness of polyvinyl chloride can be remarkably improved.

Description

technical field [0001] The application relates to the technical field of polymer materials, in particular to a rigid polyvinyl chloride pipe material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics. Its products are widely used in soft products such as packaging materials, artificial leather, and plastic products, and hard products such as profiled materials, plates, and pipes. PVC materials have good physical properties such as flame retardancy, UV resistance, strong acid and alkali corrosion resistance, and hard products have good impact resistance. In addition, polyvinyl chloride is an important chlorine-consuming product in the chlor-alkali industry. Its chlorine consumption accounts for more than 25% of the total chlorine production. all aspects of life. [0003] With the improvement of people's living standards, people's demand for decoration is more diversified, intelligent and simp...
