Abstract

The invention discloses an antibiotic strengthened polyvinyl chloride tube and a production method thereof. The antibiotic strengthened polyvinyl chloride tube comprises, by mass, 45-80% of polyvinyl chloride, 8-12% of nanometer carbon fiber, 5-10% of dioctyl phthalate, 5-10% of attapulgite, 6-9% of butadiene-acrylonitrile rubber, 3-6% of a methacrylate-acrylate copolymer, 1-3% of an antibiotic agent, 0.5-2% of a light stabilizer UV-326, 0.5-1.5% of a calcium and zinc composite stabilizer, 0.5-1% of calcium stearate and 0.1-0.5% of an antioxidant 1010. The antibiotic strengthened polyvinyl chloride tube has the advantages of excellent strengthening, antibiosis, ageing resistance and heat stability, has an antibiosis rate reaching above 98%, and also has good antibiosis and strengthening synergistic effect by adopting attapulgite as a functional filler.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to an antibacterial reinforced polyvinyl chloride pipe and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose resins, and its output is second only to polyethylene (PE). Because PVC has the advantages of high chemical resistance, good electrical insulation performance, stable physical and chemical properties, and low price, At present, it has been widely used as raw materials for pipes, wires and cables, floors, etc. However, when used as a pipe, polyvinyl chloride has problems such as poor antibacterial performance, low ring stiffness, and weak mechanical properties, which will greatly limit its application range. Contents of the invention [0003] The object of the present invention is to provide an antibacterial reinforced polyvinyl chloride pipe with excellent performance and wide adaptability and a pr...
