Problems solved by technology

[0004] Although the above construction methods have certain effects in preventing mildew, the 801 glue is gradually being eliminated due to the problem of formaldehyde pollution, and the underground space itself has the disadvantage of poor ventilation, and the residual time of formaldehyde in the underground space is relatively longer. The construction workers are more harmful and need to be improved

Embodiment 1

[0038] A method for coating a wall paint for underground space decoration, comprising the following steps,

[0039] Step 1: Remove all the original wall paint layer, and then paint the interface agent on the wall;

[0040] Step 2: Paste white glue stickers on the cracks on the wall, then lay grid cloth on the entire wall, and then brush cement mortar until the wall is flat;

[0041] Step 3: First apply a layer of putty on the base layer, then brush the putty on the surface layer twice, and then polish;

[0042] Step 4: First apply a layer of anti-alkali primer, then brush the wall paint twice;

[0043] In parts by weight, the raw material components of the wall paint are shown in Table 1.

[0044] Wherein, the preparation method of this wall paint comprises the following steps:

[0045] Step 1, add silica sol and thickener to the mixer, mix and stir until uniform, and obtain the compound glue;

[0046] Step 2, continue to put sodium metaaluminate into the agitator, continu...

Embodiment 2

[0052] The difference from Example 1 is that, in parts by weight, the raw material components of the wall paint are shown in Table 1.

Embodiment 3

[0054] The difference from Example 1 is that, in parts by weight, the raw material components of the wall paint are shown in Table 1.

Abstract

The invention discloses wall finish for underground space decoration. The wall finish is prepared from the following raw materials in parts by weight: 40-60 parts of silica sol, 220-250 parts of acrylate resin, 5-8 parts of a thickening agent, 4-7 parts of sodium metaaluminate and 7-9 parts of a mildewproof agent. Silica sol particles are ultrafine, can penetrate into a base layer through the capillary action of the wall surface and can react with calcium hydroxide in the concrete base layer to generate calcium silicate, and thus coating has high bonding force. When moisture in the silica solevaporates, colloidal ions firmly adhere to the surface of an object, and silica-oxygen bonded reticular membrane structures are formed between the particles. The silica sol can be mutually complemented with the characteristics of the acrylic resin, and thus the composite coating with excellent properties can be prepared. The sodium metaaluminate reacts with the silica sol in a silica sol system,thus a layer of zeolite film is formed on the surface of a paint film, the zeolite film is provided with a porous structure and has high catalytic activity, and the effect of the mildewproof agent oninhibiting and killing mold can be improved. The wall finish has the characteristic of good environmental protection while having a mildewproof effect.

Description

technical field [0001] The invention relates to the field of public area decoration, more specifically, it relates to a coating method and preparation method of wall paint for underground space decoration. Background technique [0002] Among the various decorative finishes, latex paint finish is favored by users as a decorative material with convenient operation, low price, simple effect and relatively strong durability. Surface materials, latex paint is also widely used in underground spaces such as basements, underground garages, underground passages, etc., but because these spaces are poorly ventilated and relatively humid, latex paint is prone to mildew, and it is difficult to control latex paint even with moisture-proof putty. Mildew, especially in June and July when the air is humid, the anti-mildew treatment of latex paint in underground space is like the prevention and treatment of chronic cardiovascular disease in the medical field, which has become a problem that h...
