Problems solved by technology

The putty powder in the prior art generally uses cement and lime calcium as bonding materials. This kind of putty is not only highly alkaline and easy to yellow, but also causes the surface of the putty layer to be coated due to the seepage of inorganic salt and water-soluble alkali The other decorative surfaces of other decorative surfaces return to alkali and bloom, which seriously affects the aesthetics. The most important thing is that the putty powder in the prior art is too alkaline, which is very easy to stimulate the construction workers, and even burn the construction workers, endangering personal safety.

Embodiment 1

[0025] The invention provides a neutral environment-friendly putty powder, which is composed of the following raw materials in parts by weight: 7-23 parts of super high-strength gypsum, 16-40 parts of calcium carbonate powder, 15-35 parts of Shuangfei powder, and 6-19 parts of diatomite , 5-15 parts of sepiolite, 0.2-1 part of hydroxypropyl methylcellulose ether, 2-8 parts of redispersible latex powder, 0.1-0.5 parts of starch ether, 1-6 parts of bentonite, 2 parts of attapulgite ~8 parts, mixed crystal titanium dioxide 0.1~1 part.

[0026] Among them, ultra-high-strength gypsum is gypsum calcined and ground at above 600°C; calcium carbonate whiteness ≥ 95%, mesh number 700-800 mesh; Shuangfei powder whiteness ≥ 90%, mesh number 200-300 mesh; silicon Celite is non-calcined diatomite with a whiteness of ≥90% and a mesh size of 380-480 mesh; sepiolite with a whiteness of ≥87% and a mesh size of 200-300 mesh; hydroxypropyl methylcellulose is the viscosity Slow-dissolving hydroxy...

Embodiment 2

[0029] Preparation of mixed crystal titanium dioxide:

[0030]Stir a titanium salt among tetraethyl titanate, butyl titanate, propyl titanate, isopropyl titanate, and titanium oxysulfate with absolute ethanol in a solvent for 2h to 10h, wherein the titanium salt, anhydrous The weight ratio of ethanol to solvent is 1:(1.5~4):(0.1~0.3), the solvent is acetylacetone or glacial acetic acid, after fully stirring, add ethanol solution with a mass fraction of 20%, wherein titanium salt and ethanol solution The weight ratio is 1: (0.5 ~ 1.2), standing for 5h ~ 24h, forming nano-mixed crystal TiO 2 Then put the sol in a drying oven, dry it at 100-150°C, put it in a muffle furnace, bake it at 500-550°C for 30-60min, take it out after natural cooling, and grind it to get the mixed crystal TiO 2 powder.

[0031] The preparation process of Example 1 and the mixed crystal titanium dioxide prepared in Example 2 will be adopted below, and the specific raw material ratio will be used to pre...

Abstract

The invention discloses a neutral environment-friendly putty powder which has the air purification property and is free of coating brushing and smooth in appearance. The putty powder is prepared from,by weight, 7-23 parts of ultra-high-strength gypsum, 16-40 parts of calcium carbonate powder, 15-35 parts of calcium carbonate, 6-19 parts of non-calcined kieselguhr, 0.2-1 part of hydroxypropyl methyl cellulose, 2-8 parts of redispersible latex powder, 0.1-0.5 part of starch ether, 1-6 parts of sodium bentonite, 5-15 parts of sepiolite, 2-8 parts of attapulgite and 0.1-1 part of mixed crystal titanium dioxide. Accordingly, the putty powder has the properties of good safety, environmental protection, water resistance, respiratory hygroscopicity, formaldehyde and harmful gas elimination and the like, and has good capacity of improving the quality of the living environment; meanwhile, the surface of the putty powder is smooth, firm and white, other coating or wallpaper can be omitted, and the effects of protecting the environment and reducing the cost can be achieved.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to the technical field of coatings, and more specifically relates to a brush-free neutral and environmentally friendly putty powder with air-purifying performance. Background technique [0002] In the field of architectural decoration, putty is a kind of surface leveling powder material that is pretreated before the construction of various wall surfaces. The main purpose is to fill the pores of the construction surface and correct the curve deviation of the construction surface, in order to obtain a uniform and smooth base surface To lay a solid foundation, this kind of ordinary putty has a single function and efficiency. After construction, it must be painted on the surface or pasted with wallpaper, etc. The process is complicated and difficult to operate. It threatens the health of indoor occupants, and the high price of environmentally friendly coatings is also prohib...
