Environment friendly antibacterial waterborne paint and preparation thereof

Abstract

The invention provides an environment-friendly antibacterial water paint and a preparation method thereof. The components include deionized water, germicide, assistant for film forming, defoaming agent, wetting agent, dispersant, nanometer TiO2, emulsion or water dispersoid resin, filler, anti-settling agent, flatting agent, thickener, pH regulator, scratch resistance agent or slipping agent, pigment or coloring agent, additive with special function and the like. The preparation method includes the steps of: A. preparing the water dispersoid; B. adding the water dispersoid obtained in the step A into the stirred emulsion, then adding the assistant for film forming, the flatting agent, the thickener, the anti-settling agent, and the pH regulator and uniformly stirring and dispersing the components; C. adding the pigment or the coloring agent; and D. charging water and adjusting the Stormer viscosity at the temperature of 25 DEG C to be 65-90KU, thus obtaining the water paint. The waterpaint provided in the invention has good adhesion to wood materials, full paint films with certain hardness, low VOC, no heavy metal, and the antibacterial and mildewproof functions, and belongs to the environment-friendly and safe children woodwork water paint.

Problems solved by technology

[0005] Children's wooden products such as children's tables, chairs, baby carriages, children's wooden toys, building blocks, pencils and other daily necessities, even if children's toys are made of water-based paint, it is not yet environmentally safe

Because it is easy to produce mold, bacteria and air pollution during the use and storage of toys, which is directly harmful to children

At present, antibacterial materials (antibacterial coatings, antibacterial plastics, antibacterial stainless steel, antibacterial paper, etc.) have appeared, but people's research on antibacterial coatings is mainly to realize the sterilization function through bactericides, which are mainly used for indoor walls, toilets, floor coatings, etc. However, for children's toys that children are in close contact with, the use of fungicides is not conducive to the health of children.
