Abstract

The invention discloses a preparation method of an antibacterial polyvinyl chloride pipe material. The preparation method comprises the following steps: mixing polyvinyl chloride and chloroprene rubber, heating and stirring, so that a first premixture is obtained; heating solid paraffin, adding octadecyl trimethyl ammonium bromide and cotton linters, stirring, carrying out microwave expansion, regulating temperature and stirring, adding a copper chloride aqueous solution, regulating temperature and stirring, cooling, drying, smashing, adding the first premixture, bentonite and calcined kaolin, uniformly stirring, adding an antioxidant, microcrystalline wax and magnesium hydroxide, uniformly stirring, cooling to room temperature, and standing, so that a second premix is obtained; and putting the second premix into an extruding machine, and extruding, so that the antibacterial polyvinyl chloride pipe material is obtained. The preparation method of the antibacterial polyvinyl chloride pipe material is simple in operation, raw materials are available, cost is low, the obtained polyvinyl chloride pipe material has excellent antibacterial property and good mechanical properties, toughness and hardness reach the equilibrium, and the antibacterial polyvinyl chloride pipe material is difficult to break.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride, in particular to a method for preparing an antibacterial polyvinyl chloride pipe. Background technique [0002] As one of the products of the development of science and technology, PVC pipes can be seen in daily life. The late 1990s was a period of rapid development of PVC pipes in mainland China. During this period, some factories with an annual production capacity of more than 50,000 tons have been built and put into operation, and there are more than 30 PVC pipe factories with an annual production capacity of more than 10,000 tons. The annual production capacity of plastic pipes is 2 million tons. However, at present, PVC pipes still have the problems of poor antibacterial properties and easy breakage, which need to be improved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a met...
