Problems solved by technology

At present, the extrusion current of PVC-M pipe is relatively high, especially the viscosity of PVC-M pipe modified by MBS and CPE is high, and the mechanical properties of the material are reduced due to the addition of a large amount of MBS toughening modifier.

Abstract

The invention belongs to the technical field of high polymer materials, and specifically relates to a high-strength PVC tubular product composition. Through the technical scheme, the high-strength PVC tubular product composition is prepared from the following components (in parts by weight): 100 parts of PVC, 2 to 4 parts of a processing modifier, 1.0 to 2.5 parts of a heat stabilizer, 8 to 11 parts of a flexibilizer, 1.5 to 3.5 parts of a lubricating agent, 0 to 5 parts of a filler, 0.05 to 0.1 part of an antioxygen 1076 and 0 to 2 parts of a coloring agent. A rigid polyvinyl chloride tubular product produced by using the composition disclosed by the invention has high tenacity and relatively high strength, and is high in impact performance and relatively high in physical and mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a high-strength PVC pipe material composition. Background technique [0002] PVC-U pipe is a commonly used plastic pipe at present, which has the advantages of light weight, corrosion resistance, convenient installation and maintenance, and low price. An important use of PVC pipes is for the construction of water supply and drainage pipe networks. In terms of water network construction, rigid PVC pipes have the advantage of longer service life than PE pipes, and the theoretical long-term strength of PVC is also higher than that of PE. Strength (PVC≥25MPa, PE≥10MPa). However, during use, it was found that PVC-U is relatively brittle, easily injured when impacted, has low impact strength, and poor crack resistance. Therefore, in recent years, domestic PVC production enterprises have begun to produce high-impact polyvinyl chloride pipes (ie PVC-M pipes). In a...
