Abstract

The invention discloses antibacterial polyvinyl chloride resin, and belongs to the technical field of resin preparation. The antibacterial polyvinyl chloride resin is prepared from polyvinyl chlorideresin, polylactic acid, organic fluorine epoxy resin, polyphenylene sulfide, polycarbonate, polyhydroxybutyrate, vinyl acetate, calcium molybdate, chitosan, zinc borate, kieselguhr, wood fiber powder,chlorinated paraffin, polyethylene glycol, trioctyl trimellitate, polycaprolactone, trimethyl phosphate, tributyl citrate, adipic dihydrazide, tartaric acid, potassium peroxodisulfate, zinc phosphate, fluorine micro powder, nanometer titania, a silane coupling agent KH-560 and antibacterial performance additives. The antibacterial polyvinyl chloride resin is prepared through the steps of preparing a base material, preparing a modified material, mixing the base material, the modified material and other materials and the like. The prepared polyvinyl chloride resin has the excellent antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of resin preparation technology, in particular to an antibacterial polyvinyl chloride resin and a preparation method thereof. Background technique [0002] The main component of polyvinyl chloride resin is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, ductility, etc. It is a well-loved, popular and widely used synthetic material in the world today. It is the second most used synthetic material worldwide. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC is being produced and applied all over the world at a growth rate of 4%. The growth rate of PVC in Southeast Asia is particularly significant, thanks to the urgent needs of infrastructure construction in Southeast Asian countries. Among the mate...
