Embodiment 1

[0015] Example 1 Preparation of functional additives.

[0016] Weigh the following components in parts by weight: 2 parts of lithium magnesium silicate, 2 parts of hydrophobic modifier, 0-1 part of solubilizer, 3 parts of organic polymer gel, 0.1 part of composite defoamer, 1 part of polyurethane solubilizer Thickener, 0.2 part of propylene glycol, 0.2 part of alcohol ester dodecane, 0.1 part of potassium salt dispersant, 0.2 part of micronized wax. The hydrophobic modifier is a nanoscale hydrophobic modifier. The organic polymer gel refers to sodium alginate.

[0017] The functional auxiliary agent is obtained by mixing the above ingredients.

Embodiment 2

[0018] Embodiment 2 Prepare the semi-finished product of colorful paint with colored particles.

[0019] Weigh 20 parts of talcum powder, 30 parts of heavy calcium, 5 parts of attapulgite powder or 5 parts of calcined kaolin, 45 parts of acrylic emulsion (PRIMAL AC-808A of Rohm and Haas International Trading (Shanghai) Co., Ltd. or Rohm and Haas International Trading (Shanghai) Co., Ltd. Primal TM DirtShield K2), 0.2 parts of Rohm and Haas International Trading (Shanghai) Co., Ltd. ASE-60, 0.2 parts of Rohm and Haas International Trading (Shanghai) Co., Ltd. TT615 or 0.2 parts of Rohm and Haas International Trading (Shanghai) Co., Ltd. RM -2020 NPR, 3 copies of Rohm and Haas International Trading (Shanghai) Co., Ltd. RM-8W.

[0020] The raw materials of the above components are mixed and stirred evenly to produce a gel semi-finished product; the color paste is added to the gel semi-finished product according to the color ratio to obtain various color gel semi-finished produc...

Abstract

The invention discloses fully water-based multicolor paint. The fully water-based multicolor paint comprises the following components in part by weight: 30 to 40 parts of organosilicone modified acrylic acid emulsion 10 to 20 parts of water, 40 to 50 parts of colorful particle multicolor paint semi-finished product, and 0 to 10 parts of functional aid. By the paint, the content of volatile organic compounds (VOC) can be effectively reduced, and the particles really have the shape of particles instead of sheets of other multicolor paint; after the paint is applied, a film is thick and solid, and sagging is avoided, so that an obvious simulation effect is achieved; and through modification of film forming substances and adding of functional aids, a product is excellent in weather resistance and water resistant performance.

Description

technical field [0001] The invention belongs to the technical field of architectural decorative coatings, and in particular relates to an all-water-based colorful coating. Background technique [0002] Water-based multi-color paint is a water-based multi-color paint composed of a water-based dispersion of colored spherical particles dispersed in an aqueous dispersion medium containing film-forming substances; the paint is mainly composed of three parts: a dispersed phase, a cross-linking solution and a protective colloid solution. Its dispersed phase is composed of pigments, fillers and film formers, etc. Among them, film formers play a major role in the dispersed phase. It not only covers the pigments, but also makes the pigments evenly distributed in the dispersed phase, and has an impact on other properties of the coating. big impact. The film former is generally an emulsion, such as pure acrylic emulsion, styrene-acrylic emulsion, vinegar-acrylic emulsion, or a mixture ...
