Preparation method of antibacterial coating for plastic surface

Abstract

The invention discloses a preparation method of an antibacterial coating for a plastic surface. The method comprises the following steps of: stirring 70-75 parts by mass of potash water glass, 1-2 parts by mass of sodium hexametahposphate, 4-5 parts by mass of zinc oxide and 10 parts by mass of copper oxide at the stirring speed of 900-1,000 revolutions per minute for one hour; adding 50-60 parts by mass of chloroethylene-vinylidene chloride emulsion and 30-40 parts by mass of vinyl-acrylic emulsion at the stirring speed of 60-80 revolutions per minute; and stirring for 30 minutes to obtain the antibacterial coating. As proved by industrial tests, the antibacterial coating can be used for effectively killing molds and other bacteria in the air. The antibacterial coating contains a sterilizing agent which has a stronger sterilizing effect and can be organically combined with various components in the coating, so that a long-term effective sterilizing effect can be achieved. The coating does not endanger the human body health; and meanwhile, the antibacterial coating is convenient to use.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial coating used on plastic surfaces, belonging to the technical field of chemical coatings. technical background [0002] At present, plastic products are widely used materials in daily life. If bacteria grow on some plastic products that people often come into contact with, it will cause certain harm to the human body. Now it is possible to prepare antibacterial plastics or coat the surface of the plastics with a layer of antibacterial coatings, but the preparation cost of antibacterial plastics is relatively high, and the process is complicated, so it is not suitable for some low-cost plastic products. Therefore, the most commonly used in the market is to apply antibacterial coatings on plastic products. However, the bactericidal effect of this type of paint on the market is not stable, and it cannot continue to sterilize for a long time, and some are poisonous. Contents of the inventi...
