Abstract

The invention provides an antibacterial mouldproof polyvinyl chloride material and a preparation method thereof. The antibacterial mouldproof polyvinyl chloride material is prepared from the following components in percentage by weight: 40-50% of PVC (polyvinyl chloride) powder, 15-20% of CaCO3, 20-25% of a polymer plasticizer, 1.5-2.5% of a calcium and zinc liquid stabilizer (968-A), 1% of CPE (chlorinated polyethylene), 1-2% of pigments and 1.5-2.0% of an inorganic antibacterial agent. The preparation method comprises the following steps: (1) dosing in a reaction kettle at normal temperature; (2) stirring; and (3) cooling and granulating: pouring the stirred material into a twin screw granulator, mixing and extruding at 130-170 DEG C, cooling by circulating water at 5-10 DEG C, extruding, airing, and finally slicing and packaging. The antibacterial mouldproof polyvinyl chloride material prepared by the preparation method provided by the invention is applied to plastic parts of consumer electronics products and has the characteristics of being good in antibacterial mouldproof effect, stable in performance and the like.

Description

technical field [0001] The invention relates to an antibacterial and mildew-proof plastic, in particular to an antibacterial and mildew-proof polyvinyl chloride material. Background technique [0002] The living environment of modern people is full of various plastic products, ranging from simple to basic livelihood products, such as various household plastic shells, plastic parts of consumer electronics products, insulation materials for various wires and cables, etc. Plastics are easy to be contaminated and contaminated during use. Breed a variety of microorganisms, such as polyvinyl chloride (PVC) electronic materials in a damp state, it is easy to mold and breed a variety of pathogenic bacteria, which is harmful to human health. Antibacterial and anti-mildew modification treatment is carried out for plastic materials to achieve anti-bacterial and anti-mildew effects. Antibacterial polyvinyl chloride is a new type of material with antibacterial and bactericidal propertie...
