Abstract

The invention discloses a low-volatility and quick-drying aqueous toy coating and a preparation method thereof. The formula of the coating comprises the following components in percentage by weight: 52-80 percent of polymer water dispersion, 1-25 percent of film-forming agent semi-finished product, 0-30 percent of aqueous pigment and filler, 0.1-5 percent of aqueous auxiliary agent and 1.1-40 percent of deionized water. The aqueous auxiliary agent is one or more selecting from a defoamer, a wetting agent, a dispersing agent, a surface effect control agent, a rheology anti-settling agent, a thickening agent, an adhesive force accelerator and a pH value regulator. The invention is suitable for spraying construction of toys using plastic, metal, wood and the like as substrates, and has the characteristics of good adhesive force, low volatility, high drying speed and high film surface glossiness.

Description

technical field [0001] The invention relates to a water-based paint and a preparation method thereof, in particular to a paint suitable for plastics, [0002] Low-volatility, fast-drying water-based toy paint for metal, wooden and other substrate toys and a preparation method thereof. Background technique [0003] China is a big manufacturer of children's toys, with annual output accounting for 60-70% of the world's total, and most of the toy production is concentrated in the Pearl River Delta. Most of the toy products use plastic substrates, which are of high quality and low price. The plastic toy coatings used are mainly solvent-based. According to incomplete statistics, the current domestic consumption of solvent-based coatings for plastics exceeds 120,000 tons per year, of which toy coatings account for about 10-12%. However, solvent-based coatings are flammable and explosive, and there are many unsafe factors in the process of production, storage, transportation and ...
