Abstract

The invention relates to a novel multi-layer composite polyvinyl chloride antibacterial pipeline. The novel multi-layer composite polyvinyl chloride antibacterial pipeline comprises an outer layer, anintermediate layer and an inner layer which are successively arranged from outside to inside, wherein the intermediate layer comprises the following components by weight: 60 to 80 parts of PVC resin,10 to 30 parts of an impact modifier, 10 to 30 parts of a toughening modifier, 3 to 6 parts of a stabilizer, 1 to 3 parts of a lubricant, 2 to 5 parts of a coupling agent, 0 to 15 parts of a fillingagent and 1 to 4 parts of hexamethylphosphoric triamide. The novel multi-layer composite polyvinyl chloride antibacterial pipeline provided by the invention increases the toughness of a PVC pipe, endows an antibacterial effect to the PVC pipe at the same time, improves the anti-aging ability of the PVC pipe, and enables the PVC pipe to obtain strong comprehensive performance.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to a novel multilayer composite polyvinyl chloride antibacterial pipeline. Background technique [0002] Polyvinyl chloride, referred to as PVC in English, is a general-purpose plastic with a large output in the world. It is widely used, and it is widely used in various aspects such as building materials, industrial products, and daily necessities. Compared with other materials, PVC has rich raw materials, simple processing technology, light material, waterproof and moisture-proof, flame-retardant and heat-insulating, and also has certain chemical resistance and excellent electrical insulation. [0003] However, PVC materials generally have the problems of poor impact strength and insufficient toughness. Due to these deficiencies, the pipes made of this material are relatively brittle, and brittle failures are extremely prone to occur during product transportation, installation an...
