Problems solved by technology

[0005] Although the current wall coatings are of various types and have different performances, no matter the exterior wall or interior wall coatings, there are deficiencies in water resistance. Although some coatings have certain water resistance, they are prone to mildew after the wall is damp, and Difficult to clean after mildew, resulting in poor cleanliness of the wall

Embodiment 1

[0025] The preparation of water hyacinth additive, concrete method is:

[0026] (1) Take fresh water hyacinth, shrink to 50% of the original weight at room temperature, then soak in saturated copper sulfate solution for 3-5h, take it out, dry it at 50-80°C and crush it to 200 mesh;

[0027] (2) Dissolve hydroxyethyl cellulose into saturated sodium hydroxide aqueous solution at a ratio of 1:2 to sodium hydroxide, stir for 30 minutes, and then dissolve the product obtained in step (1) according to the mass of hydroxyethyl cellulose The ratio is 1:1, add to the mixture, heat up to 50-60°C, stir and react for 30-60min;

[0028] (3) Adjust the pH of the reaction solution to neutral, and then filter to obtain the water hyacinth additive.

[0029] The preparation of modified hydroxyapatite, the method is specifically as follows:

[0030] Take fresh water hyacinth and dry it at 50-80°C, then crush it to 100-200 mesh, reflux extraction with water at 100°C for 1-2h, the mass ratio of ...

Embodiment 2

[0034] The preparation of water hyacinth additive and modified hydroxyapatite is the same as in Example 1.

[0035] A kind of wall paint for building, its raw materials are prepared according to weight parts (100g per part): 50 parts of water-based acrylic resin, 10 parts of water-based acrylic modified epoxy resin, 20 parts of polydimethylsiloxane, organic 18 parts of solvent (xylene or butyl acetate), 5 parts of kaolin, 3 parts of iron oxide, 5 parts of nano-titanium dioxide, 5 parts of water hyacinth additive, 2 parts of cuprous sulfate, 1 part of iodopropynyl butyl carbamate 10 parts of modified hydroxyapatite, 5 parts of N-methylpyrrolidone.

[0036] After the raw materials are prepared, add the solid components of each component into the liquid components, and stir at 50°C for 30 minutes to obtain the finished product.

Embodiment 3

[0038] The preparation of water hyacinth additive, concrete method is:

[0039] (1) Take fresh water hyacinth, shrink to 40% of the original weight at room temperature, soak in acetic acid solution with a mass concentration of 10% for 10-20min, then soak in saturated copper sulfate solution for 3-5h, after taking it out, put it in 50 Dry at -80°C and crush to 200 mesh;

[0040] (2) Dissolve hydroxyethyl cellulose into saturated sodium hydroxide aqueous solution at a ratio of 1:2 to sodium hydroxide, stir for 30 minutes, and then dissolve the product obtained in step (1) according to the mass of hydroxyethyl cellulose The ratio is 1:1, add to the mixture, heat up to 50-60°C, stir and react for 30-60min;

[0041] (3) Adjust the pH of the reaction solution to neutral, and then filter to obtain the water hyacinth additive.

[0042] The preparation of modified hydroxyapatite, the method is specifically as follows:

[0043]Take fresh water hyacinth and dry it at 50-80°C, then cru...

Abstract

The invention relates to the technical field of coatings, in particular to a wall coating for buildings. The wall coating for the buildings contains following constituents of, based on weight parts, 30-50 parts of aqueous acrylic resin, 10-20 parts of aqueous acrylic modified epoxy resin, 10-20 parts of dimethyl silicone polymer, 18-27 parts of organic solvent, 3-5 parts of kaolin, 3-5 parts of ferric oxide, 2-5 parts of nanometer titania, 5-10 parts of water hyacinth additives, 1-2 parts of cuprous sulfate, 1-3 parts of butyl and amidogen formic acid iodination allylene ester and 5-10 parts of modified hydroxyapatite. The wall coating for the buildings can effectively resist bacteria, prevents a wall surface from being affected with damp and mildewing, and thereby keeps the wall surface smooth and clean.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a building wall coating. Background technique [0002] Wall paint refers to the decoration and protection of the building wall, making the building wall beautiful and tidy, and at the same time protecting the building wall and prolonging its service life. According to the classification of building walls, wall coatings include two major parts: interior wall coatings and exterior wall coatings. Interior wall coatings focus on decoration and environmental protection; exterior wall coatings focus on protection and durability. In addition to its own decorative and protective functions, wall paint is also developing towards a colorful, fashionable, healthy and environmentally friendly trend. People hope that the decorative effect will be radiant and beautiful, noble, elegant, romantic, and warm; they also hope that the material itself is pollution-free, healthy and environmentally ...
