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 water paint 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.

Description

Technical field [0001] The invention relates to an environmentally-friendly antibacterial water-based paint, in particular to an environmentally-friendly antibacterial water-based paint for children's wood products. [0002] The invention also relates to a preparation method of the environmentally friendly antibacterial water-based paint for children's wood products. Background technique [0003] The topic of environmental protection and health of children's homes raised by the "toy recall" incident has also caused the public to pay more attention to the quality and safety of toys, furniture and other products related to children's health.
