Problems solved by technology

[0006] However, PVC pipes often have problems of not being able to withstand pressure and impact, so that problems such as breakage, cracking, and damage will occur during installation and use, and the heat resistance of PVC pipes is not particularly high. Working in an environment where there will be deformation problems, which will lead to a sharp reduction in service life, and maintenance and replacement are very troublesome, and it will greatly affect the use

Abstract

The invention discloses a composite filler for a PVC pipe, and relates to the technical field of PVC pipe processing and manufacturing. The composite filler is characterized by being prepared from, byweight, 4-8 parts of resin, 3-7 parts of defoamer, 5-9 parts of modified fluorite powder, 1-3 parts of ethyl alcohol, 4-7 parts of non-metallic ceramic powder, 1-4 parts of chitosan, 1-5 parts of sulfur-phosphorus primary-secondary alkyl zinc salt, 1-3 parts of adjacent benzene twoforMic acid diethylene glycoltwo acrylate, 1-3 parts of octane amine, 1-3 parts of tetramethyl thiuram disulfide, 1-4parts of polycaprolactone, 4-8 parts of fiber filler and 20-27 parts of deionized water. Accordingly, the method is reasonable, and abrasive resistance, heat resistance and toughness can be improved.

Description

technical field [0001] The invention relates to the technical field of PVC pipe processing and production, in particular to a composite filler for PVC pipes. Background technique [0002] Polyvinyl chloride, referred to as PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloridemonomer, referred to as VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat, it can be polymerized according to the mechanism of free radical polymerization. made polymer. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. [0003] PVC is a white powder with an amorphous structure, the degree of branching is small, the relative density is about 1.4, the glass transition temperature is 77-90°C, it begins to decompose at about 170°C, and it has poor stability to light and heat. When exposed to sunlight, it will decompose to produce hydrogen chloride, and further autocatalyze the decompos...
