Problems solved by technology

[0011] Aiming at the problems of poor weather resistance and stain resistance in traditional emulsion paints for exterior walls, the purpose of the present invention is to provide a preparation method of water-based metallic paint and a kind of water-based metallic paint prepared therefrom. Wall paint not only has better weather resistance and stain resistance than traditional latex paint, but also has superior chemical resistance, adhesion resistance, and scrub resistance. It is an environmentally friendly paint

Embodiment 1

[0024] The raw materials are mixed and stirred until the paint fineness reaches ≤50μm and is in a uniform state. The raw materials used and their weight parts are: 3.0 parts of deionized water, 79.0 parts of acrylic acid ester, 0.4 parts of potassium salt of acrylic acid copolymer, and thickener 0.2 part of hydroxyethyl cellulose carboxylate, nano-scale SiO 2 4.0 parts, 5.0 parts of water-based metallic glitter powder, 0.6 parts of organic silicon oil, 1.5 parts of ZH-10, 0.5 parts of anti-mold bactericide. Then add the following parts by weight of additives to the above-prepared solution and stir evenly. The additives used are 0.5 parts of BCS, 1.5 parts of propylene glycol, 0.2 parts of acrylic associative thickener, 4.0 parts of alcohol ester 12, and pH regulator 0.061 parts. Then, it is packaged to obtain the water-based metallic paint of the present invention.

Embodiment 2

[0026] The raw materials are mixed and stirred until the paint fineness reaches ≤50um and is in a uniform state. The raw materials and parts by weight are: 5.0 parts of deionized water, 77.0 parts of acrylic acid ester, 0.8 parts of potassium salt of acrylic acid copolymer, and thickener hydroxyl 0.1 part of ethyl cellulose carboxylate, nano SiO 2 3.0 parts, 7.0 parts of water-based metallic glitter powder, 0.4 parts of silicone oil, 2.0 parts of ZH-10, 0.8 parts of anti-mold bactericide. Then add the following parts by weight of additives to the above-prepared solution and stir evenly. The additives used are 1.0 part of BCS, 1.0 part of propylene glycol, 0.3 part of acrylic associative thickener, 3.0 parts of alcohol ester 12, and pH regulator 0.1 part. Then, it is packaged to obtain the water-based metallic paint of the present invention.

Embodiment 3

[0028] The raw materials are mixed and stirred until the paint fineness reaches ≤50μm and is in a uniform state. The raw materials and parts by weight are: 4.0 parts of deionized water, 78.0 parts of acrylic acid ester, 0.6 parts of potassium salt of acrylic acid copolymer, and thickener hydroxyl. 0.15 parts of ethyl cellulose carboxylate, nano SiO 2 3.5 parts, 6.0 parts of water-based metallic glitter powder, 0.5 parts of silicone oil, 1.8 parts of ZH-10, 0.7 parts of anti-mold bactericide. Then add the following parts by weight of additives to the above prepared solution and stir evenly. The additives used are 0.8 parts of BCS, 1.2 parts of propylene glycol, 0.25 parts of acrylic associative thickener, 12 parts of alcohol ester, 3.5 parts of PH adjuster 0.08 parts. Then, it is packaged to obtain the water-based metallic paint of the present invention.

Abstract

A preparation method of a water-based metallic paint for walls and the water-based metallic paint prepared by the method are prepared by the following method: deionized water, acrylate, acrylic acid copolymer potassium salt, thickener hydroxyethyl carboxylic acid Cellulose, Nano SiO 2 , water-based metal glitter powder, silicone oil, ZH-10, and anti-mildew fungicide are mixed in a certain proportion, and stirred until the paint fineness reaches ≤50 μm and is in a uniform state; then a certain proportion of BCS, propylene glycol, and acrylic acid association Thickener, alcohol ester 12, and pH regulator are added to the above solution and stirred evenly. This kind of water-based metallic paint has rich colors, strong metallic texture, good weather resistance, high stain resistance, strong washing resistance, convenient maintenance, environmental protection and pollution-free, and has a wide range of applications. It can be used not only for exterior walls, but also for on the interior wall.

Description

Technical field [0001] The invention relates to a preparation method of a water-based metallic paint and a water-based metallic paint prepared therefrom, which is an environmentally-friendly wall paint. Background technique [0002] At present, the wall paints used for exterior walls include latex paint and solvent-based metal paint. Traditional latex paints for exterior walls are made of acrylic emulsion. This latex paint has the following disadvantages: [0003] (1) The weathering durability is poor, about 5-8 years; [0004] (2) Poor stain resistance. After 1 year of painting on the exterior wall, the surface of the paint film will be covered with dust. After rain washing, there are many stripes on the surface. Even if it is manually washed, there are 20% The remaining traces are difficult to remove, which affects the appearance of the exterior wall; [0005] (3) No metallic luster and poor gloss retention. [0006] The disadvantages of solvent-based metallic paints such as PU...
