Problems solved by technology

[0003] Water-based polyurethane and water-based acrylic emulsion are the most commonly used resins in water-based wood paints. Traditional acrylic resins are used as film-forming wood paints, namely acrylic water-based paints, which have the advantages of good weather resistance and fast drying, accounting for most of them. However, its wear resistance and water resistance are not good, and its physical and chemical properties are not ideal. How to further improve this kind of wood paint and improve its physical and chemical properties is a major research direction in this field.

Embodiment 1

[0044] The acrylic water-based paint of the present invention comprises the following components by weight:

[0045]

[0046]

[0047] The method for preparing the above-mentioned acrylic water-based paint using this formula is as follows: according to the content of each component in the above-mentioned formula, water, nano-calcium carbonate, bentonite, talcum powder, wetting agent, dispersant and defoamer are added to the high-speed dispersion tank, Stir and disperse at high speed to obtain a slurry; add silicone-modified acrylic emulsion and film-forming aids to the slurry, stir and disperse to obtain a semi-finished product, add a pH regulator to adjust the pH value to 7-8; pass the semi-finished product through 200 mesh yarn Filter through a net to obtain acrylic water-based paint.

[0048] Wherein, the preparation method of silicone-modified acrylic emulsion is: add persulfate as initiator in acrylate (hard monomer) and acrylic acid (soft monomer), optimize the rat...

Embodiment 2

[0052]Different from Example 1, the acrylic water-based paint of the present invention includes the following components by weight:

[0053]

[0054]

[0055] Among them, the film-forming aid is composed of 70% tripropylene glycol methyl ether and 30% DALPAD H.

[0056] In this embodiment, the wetting agent is the polyether-modified organosilicon compound of Germany BYK; the dispersant adopts 5040; the defoamer is the organic silicon defoamer of Germany BYK; Disodium hydrogen phosphate is used; the particle size of nano-calcium carbonate is 30nm; the particle size of bentonite is 300 mesh; the particle size of talcum powder is 700 mesh.

Embodiment 3

[0058] Different from Example 1, the acrylic water-based paint of the present invention includes the following components by weight:

[0059]

[0060] The film-forming aid is compounded by dipropylene glycol n-butyl ether and dipropylene glycol methyl ether in a ratio of 1:1.

[0061] In this embodiment, the wetting agent is K12; the dispersant is the polyacrylate dispersant of German BK Baker Gilini Company; the defoamer is polyether defoamer; 95pH regulator; nano calcium carbonate particle size is 50nm; bentonite particle size is 300 mesh; talcum powder particle size is 800 mesh.

Abstract

The invention relates to an acrylic acid water-based paint comprising the following components in parts by weight: 50-70 parts of organic modified acrylic acid emulsion, 5-10 parts of nano calcium carbonate, 1-10 parts of bentonite, 5-15 parts of talcum powder, 0.1-1.0 part of a wetting agent, 1-3 parts of a dispersing agent, 0.1-0.5 part of a defoaming agent, 1-4 parts of a coalescing agent and 1-25 parts of water, wherein the coalescing agent is compounded of dipropylene glycol n-butyl ether and dipropylene glycol methyl ether at a molar ratio of 1:(1-3). The acrylic acid water-based paint has good abrasive resistance, water resistance, resistance to soiling and scratch resistance, high hardness and excellent physical and chemical property.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to an acrylic water-based paint and a preparation method thereof. Background technique [0002] Wood paint is mainly used on the surface of furniture, floors, etc. It not only has the effect of decoration and beautification, but also can protect wood. Water-based wood paint has become the first choice for wood paint because of its green and environmental protection. [0003] Water-based polyurethane and water-based acrylic emulsion are the most commonly used resins in water-based wood paints. Traditional acrylic resins are used as film-forming wood paints, namely acrylic water-based paints, which have the advantages of good weather resistance and fast drying, accounting for most of them. However, its wear resistance and water resistance are not good, and its physical and chemical properties are not ideal. How to further improve this kind of wood paint and improve its physi...
