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

[0025] Mix and stir the raw materials until the paint fineness reaches ≤50 μm and is in a uniform state. The raw materials used and their parts by weight are: 3.0 parts of deionized water, 79.0 parts of acrylate, 0.4 parts of potassium salt of acrylic acid copolymer, thickener Hydroxyethyl carboxylate cellulose 0.2 parts, nano-sized SiO 2 4.0 parts, water-based metal glitter powder 5.0 parts, silicone oil 0.6 parts, ZH-10 1.5 parts, anti-mildew fungicide 0.5 parts. Then add the following additives in parts by weight to the solution prepared above and stir evenly. The additives used are 0.5 parts of BCS, 1.5 parts of propylene glycol, 0.2 parts of acrylic acid associative thickener, 4.0 parts of alcohol ester 12, and a pH regulator 0.061 parts. Then packing just obtains water-based metallic paint of the present invention.

Embodiment 2

[0027] Mix and stir the raw materials 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 acrylate, 0.8 parts of potassium salt of acrylic acid copolymer, thickener hydroxyl 0.1 part of cellulose ethyl carboxylate, nano-sized SiO 2 3.0 parts, water-based metal glitter powder 7.0 parts, silicone oil 0.4 parts, ZH-10 2.0 parts, anti-mildew fungicide 0.8 parts. Then add the following additives in parts by weight to the solution prepared above and stir evenly. The additives used are 1.0 parts of BCS, 1.0 parts of propylene glycol, 0.3 parts of acrylic acid association thickener, 3.0 parts of alcohol ester 12, and a pH regulator 0.1 part. Then packing just obtains water-based metallic paint of the present invention.

Embodiment 3

[0029] Mix and stir the raw materials until the paint fineness reaches ≤50 μm and is in a uniform state. The raw materials and parts by weight are: 4.0 parts of deionized water, 78.0 parts of acrylate, 0.6 parts of potassium salt of acrylic acid copolymer, thickener hydroxyl Cellulose ethyl carboxylate 0.15 parts, nano-sized SiO 2 3.5 parts, 6.0 parts of water-based metal glitter powder, 0.5 parts of organic silicone oil, 1.8 parts of ZH-10, 0.7 parts of anti-mold and fungicide. Then add the following additives in parts by weight to the solution prepared above and stir evenly. The additives used are 0.8 parts of BCS, 1.2 parts of propylene glycol, 0.25 parts of acrylic acid association thickener, 3.5 parts of alcohol ester 12, and a pH regulator 0.08 parts. Then packing just obtains water-based metallic paint of the present invention.

Abstract

A process for preparing metallic water paint includes such steps as proportionally mixing deionized water, acrylate, potassium salt of acrylic copolymer, hydroxyethyl carboxylate cellulose, nano SiO2, metallic water flashing powder, organic silica oil, ZH-10 and anti-mildew bactericiding agent, stirring, proportionally adding BCS, propanediol, thicking agent, alkoxide 12 and pH regulator, and stirring. Its advantages are rich colors, strong metallic feeling, high weatherability, durability and resistance to pollution and brush, and no environmental pollution.

Description

technical field [0001] The invention relates to a preparation method of water-based metallic paint and the prepared water-based metallic paint, which is an environment-friendly wall paint. Background technique [0002] At present, the wall paint used for exterior walls includes latex paint and solvent-based metal paint. The traditional latex paint for exterior walls is made of acrylate emulsion. This latex paint has the following disadvantages: [0003] (1) The durability of weather resistance is poor, about 5-8 years; [0004] (2) The stain resistance is poor. After one year of painting on the exterior wall, the surface of the paint film is covered with dust, and after being washed by rainwater, there are many streaks on the surface. Even if it is washed manually, there are 20% The traces left behind are difficult to remove, which affects the appearance of the exterior wall; [0005] (3) No metallic luster, poor gloss retention. [0006] The disadvantages of solvent-base...
