Abstract
The invention discloses water-base toy paint and a production process, which is prepared by dispersion resin, propanediol ether, 20% ammonia, deionized water, ruite titanium dioxide, ultra-fine talc, 15-25 ultra-fine calcium carbonate and defoaming agent. The production process comprises adding dispersion resin, propanediol ether, ammonia, deionized water into a material-preparing pot, evenly agitating and mixing in low speed, then adding defoaming agent to evenly mix, adding pigment and filler to form even paint paste through dispersing in high speed, throwing paint paste into a regulating tank after grinding, agitating to mix evenly in low speed, adding deionized water to dilute. The paint of the invention has environmental-friendly water-base, fast coalescence to blocks, excellent sealing and anti-bonding property, can effectively make up the partial weaknesses and shortcomings of substrate material, prevents the generation of wood grease and spurs, has strong adhesion, high painting film, favorable binding resistance, excellent flat surface of paint film, water resistance and stability, and has excellent toughness, no tending to get soft and corrosion resistance and suitable price.
Description
1. Technical field [0001] The invention belongs to a toy paint and a preparation method thereof. 2. Background technology [0002] my country is one of the major toy-producing countries in the world. The children's toys produced are mainly exported to the United States and Europe. Most of the children's toys are painted with solvent-based paints, which are characterized by fast drying, high hardness, and good adhesion resistance. However, due to the volatilization of harmful aromatic solvents such as benzene, toluene, and xylene in the coating process, the paint film contains harmful heavy metal lead, which seriously affects the environment and is gradually banned. [0003] Water-based toy paint has emerged as the times require, and its performance fully meets the requirements of environmental protection standards, becoming a substitute for solvent-based toy paint. [0004] Most of the water-based toy paints on the market are based on acrylic or polyurethane emulsions, and a...
