Abstract

The invention discloses a preparation method of water-resisting antibacterial plastic master batch. The preparation method comprises the following steps: (1) adding 1,2-cyclohexanediamine into water,slowly adding sulfuric acid until no white precipitates are generated, filtering, cleaning the filter residues, drying to obtain 1,2-CDTA; (2) adding 1,2-CDTA, isopropoxyboronic acid pinacol ester, sebacic acid disodium salt, stearyl monoglyceridyl citrate and nano ITO into a high-speed mixer, uniformly mixing to obtain a water-resisting antibacterial agent; and (3) uniformly mixing the water-resisting antibacterial agent and polyethylene resin according to a ratio of 1: (4 to 6), adding the mixture into a double-screw extruder, extruding, granulating to obtain functional master batch. The water-resisting antibacterial plastic batch prepared by the method provided by the invention is excellent in various mechanical performance, excellent in aging resistance, good in water immersion resistance, and still excellent in antibacterial performance after being immersed in water for a long time.

Description

technical field [0001] The invention belongs to the technical field of antibacterial plastic preparation, and in particular relates to a preparation method of water-resistant and antibacterial plastic masterbatch. Background technique [0002] People come into contact with all kinds of bacteria-carrying objects every day, such as telephones, washing machines, computers, electrical switches, etc., which will become sources of bacterial pollution and disease transmission. To this end, researchers have carried out research work on various antibacterial materials and antibacterial products. Among all kinds of antibacterial products, antibacterial plastics have been widely concerned in recent years because they are closely related to people's lives. The research on antibacterial plastics began in the 1980s. In recent years, antibacterial plastics in developed countries such as Japan, the United States, and Western Europe have made great progress. Especially in Japan, the applic...
