Embodiment 1

[0017] Stir and pre-disperse 19kg of silicon-containing block copolymer dispersant, 20kg of water, 0.3kg of silicone defoamer and 20kg of isoindolin-1-one colored pigment until there is no raw powder. Next, sand mill in a basket sand mill until the predetermined fineness is less than or equal to 20 μm, add 70 kg of styrene-acrylic emulsion that has been stirred for 15 minutes in advance, 0.25 kg of silicone leveling agent, and 0.25 kg of silicone defoamer. kg, propylene glycol monoethyl ether film-forming agent 7kg, triethylamine neutralizing agent 0.25kg, hard polyethylene emulsified paraffin 4kg and water 6kg mixed solution, stirring at a medium speed of 500-800 rpm for 15min, adding association type 0.25 kg of the polyurethane thickener was stirred at a medium speed for 15 min until the viscosity reached 95 s and the solid content was 50% by weight. Then make water-based wooden toy paint. The drying time of the paint is 0.5hr on the table, 48hr on the hard work, and the an...

Embodiment 2

[0019] In addition to adding 25kg of silicon-containing block copolymer dispersant, 25kg of deionized water, 0.1kg of organic silicon defoamer and 6kg of phthalocyanine blue, the preparation of the pigment slurry was the same as in Example 1. During the paint preparation process, 80kg of styrene-acrylic emulsion, 0.4kg of silicone leveling agent, 0.4kg of silicone defoamer, 0.4kg of trimethylpentanediol monoisobutyrate, diethyl Amine neutralization aid 0.4kg, hard polyethylene emulsified paraffin 2kg and water 10kg. Stir at a medium speed of 500-800 rpm for 10 minutes, and add 0.4 g of associative polyurethane thickener. Stir at medium speed for 10 minutes. Other operating steps are as in Example 1, until the viscosity reaches 80s and the solid content is 43% by weight, then a water-based wooden toy paint is made. The drying time of this paint is 0.5hr for surface dryness, 48hr for hard work, and the anti-sticking property is grade 1.

Embodiment 3

[0021] In addition to adding 12.5kg silicon-containing block copolymer dispersant, 14kg deionized water, 0.4kg silicone defoamer and 30kgTiO 2 Except, other operating steps are the same as in Example 1. In addition to adding 60kg of styrene-acrylic emulsion, 0.1kg of silicone leveling agent, 5kg of propylene glycol monoethyl ether, 0.1kg of triethylamine, 6kg of hard polyethylene emulsified paraffin and 2kg of water mixed solution in the paint preparation process Stir at a medium speed of 500-800 rpm for 20 minutes, add 0.1 kg of associative polyurethane thickener, and stir at a medium speed for 20 minutes. Other operations are the same as in Example 1 to make a water-based wooden toy paint. The resultant viscosity is 120s. The content is 48% by weight, the drying time of the paint is 0.5 hr for surface dry, 48 hr for solid dry, and the anti-sticking property is grade 1.

Abstract

A waterborne wood toy coating is provided, which is produced by the styrene-acrylic emulsion, organic silicon (flatting agent, antifoamer), polyol ester, polyol ether, water, color sizing or filler pulp. The coating is friendly to the environment and does not contain heavy metal and other toxic substances, conforms to the requirements of the European toy test instruction EN-71parts and the toy safety standards of ASTMF963, which is a green environment protection coating having no harm to the health of the children. The viscidity of the watercolor primer is 100S plus or minus 30S, content of solid is not less than 41 per cent. The viscidity of the watercolor primer is 90S plus or minus 30S and the content of solid is not less than 30 per cent.

Description

1. Technical field [0001] The invention relates to a water-based wooden toy paint, in particular to a water-based paint for painting wooden toys. 2. Background technology [0002] Water-based wooden toy paint is a leap forward from a technical point of view. Wooden toy paint is converted from solvents to low-toxic and non-toxic solvents. Water-based paint for wooden toys is the current state of the art. Fashion. However, the current commercially available water-based wooden toy paint has the disadvantages of poor anti-adhesion and slow drying. These commercially available paints need to be further improved. 3. Contents of the invention [0003] The inventors of the present invention have proposed a complete scheme for the preparation of water-based wooden toy paint after years of specialized research, and the prepared water-based wooden toy paint can overcome the shortcomings of poor anti-sticking property and slow drying. [0004] The composition of the water-based woo...
