Problems solved by technology

[0005] This kind of latex paint has good hydrophilicity, and there are usually tiny pores in the coating film. Therefore, when dirt adheres to the surface of the coating film, it will be absorbed by water vapor in the air due to the action of capillary force. Absorbed into the coating film, so that the stain resistance of the coating film is poor, which needs to be improved

Embodiment 1

[0033] Embodiment 1, a kind of environment-friendly latex paint, by weight, the composition of raw material is as shown in table 1. Wherein, the latex paint is prepared through the following steps:

[0034] Step 1, add water to the mixer, add hydroxyethyl cellulose, carboxymethyl cellulose, stir evenly, add ammonia water to dissolve the hydroxyethyl cellulose and continue stirring until uniform to obtain a compound glue;

[0035] Step 2, continue to drop into the sodium hexametaphosphate solution dissolved in hot water in the mixer, then drop into sodium methylene dinaphthalene sulfonate and stir evenly, continue to drop into terpineol and stir evenly to obtain a mixed glue;

[0036] Step 3: Stir vinyltrimethoxysilane and nano-silica evenly, put them into a blender and mix with the mixed glue to a uniform state, then add nano-titanium dioxide and continue to stir evenly to obtain a mixed slurry;

[0037] Step 4, putting the mixed slurry into a sander for grinding to obtain a ...

Embodiment 2

[0039] Embodiment 2, an environment-friendly latex paint, differs from Embodiment 1 in that, by weight, the components of the raw materials are as shown in Table 1.

Embodiment 3

[0040] Embodiment 3, an environment-friendly latex paint, the components of the raw materials are shown in Table 1 in parts by weight. Wherein, the latex paint is prepared through the following steps:

[0041] Step 1, add water to the mixer, add hydroxyethyl cellulose, carboxymethyl cellulose, stir evenly, add ammonia water to dissolve the hydroxyethyl cellulose and continue stirring until uniform to obtain a compound glue;

[0042] Step 2, continue to drop into the sodium hexametaphosphate solution dissolved in hot water in the mixer, then drop into sodium methylene dinaphthalene sulfonate and stir evenly, continue to drop into terpineol and stir evenly to obtain a mixed glue;

[0043] Step 3: Stir vinyltrimethoxysilane and nano-silica evenly, put them into a mixer and mix with the mixed glue to a uniform state to obtain a mixed slurry;

[0044] Step 4, putting the mixed slurry into a sander for grinding to obtain a finely ground slurry;

[0045] Step 5, uniformly mixing th...

Abstract

The invention discloses environment-friendly emulsion paint and belongs to the field of environment-friendly decorative materials. The emulsion paint comprises raw materials in parts by weight as follows: 200-300 parts of acrylic emulsion, 2-6 parts of a thickener, 6-12 parts of a dispersing agent, 2-10 parts of a coalescing agent, 2-8 parts of nano-silica and 2-8 parts of vinyltrimethoxysilane. The environment-friendly emulsion paint has the following beneficial effects: nano-silica can coalesce into a net structure, and strength and washability of a coating are improved; pores and bubbles exist in a film, the pores can be filled with nano-silica, density of the coating is improved, dirt is not prone to adhesion, and contrast ratio and stain resistance of the paint are improved. Vinyltrimethoxysilane can be subjected to a reaction with hydroxy on the nano-silica surface, so that nano-silica subjected to surface treatment can be tightly bound with a polymer in the acrylic emulsion through grafting, copolymerization and other reactions, stable core-shell composite emulsion is formed, and stain resistance of the emulsion paint is further improved.

Description

technical field [0001] The invention relates to the field of environment-friendly decoration materials, more specifically, relates to an environment-friendly latex paint. Background technique [0002] Environmentally friendly paint, referred to as environmentally friendly paint, refers to paint products that meet the technical requirements of national environmental labeling products on the premise that the performance indicators and safety indicators of paint products meet their respective product standards. A general term for a class of liquid or solid materials that can form a solid coating film with protective, decorative or special properties when applied to the surface of an object. [0003] Latex paint is a common name for latex paint, and it is a large class of synthetic resin emulsion paint represented by acrylate copolymer emulsion. Latex paint is a water-dispersible paint, which is based on resin emulsion, and the filler is refined by adding various additives afte...
