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 specific method for preparing water hyacinth additive is:

[0026] (1) Take fresh Eichhornia crassipes, shrink it to 50% of its original weight at room temperature, then soak it in a saturated copper sulfate solution for 3-5 hours, after taking it out, dry it at 50-80°C and crush it to 200 mesh;

[0027] (2) Dissolve hydroxyethyl cellulose into a saturated aqueous solution of sodium hydroxide at a ratio of 1:2 to sodium hydroxide, stir for 30 minutes, and then combine the product obtained in step (1) with the quality of hydroxyethyl cellulose The ratio of 1:1 is added to the mixed solution, the temperature is raised to 50-60℃, and the reaction is stirred 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 method of modified hydroxyapatite is specifically as follows:

[0030] Take fresh water hyacinth and dry it at 50-80℃, then crush it to 100-200 mesh, and extract with w...

Embodiment 2

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

[0035] A wall paint for construction. The raw materials are prepared in parts by weight (100g each): 50 parts of water-based acrylic resin, 10 parts of water-based acrylic modified epoxy resin, 20 parts of polydimethylsiloxane, organic Solvent (xylene or butyl acetate) 18 parts, kaolin 5 parts, iron oxide 3 parts, nano titanium dioxide 5 parts, water hyacinth additive 5 parts, cuprous sulfate 2 parts, butyl carbamate iodopropynyl ester 1 part ; 10 parts of modified hydroxyapatite, 5 parts of N-methylpyrrolidone.

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

Embodiment 3

[0038] The specific method for preparing water hyacinth additive is:

[0039] (1) Take fresh Eichhornia crassipes, shrink to 40% of its original weight at room temperature, first soak it in an acetic acid solution with a mass concentration of 10% for 10-20 minutes, and then soak it in a saturated copper sulfate solution for 3-5 hours. Dry at -80℃ and crush to 200 mesh;

[0040] (2) Dissolve hydroxyethyl cellulose into a saturated aqueous solution of sodium hydroxide at a ratio of 1:2 to sodium hydroxide, stir for 30 minutes, and then combine the product obtained in step (1) with the quality of hydroxyethyl cellulose The ratio of 1:1 is added to the mixed solution, the temperature is raised to 50-60℃, and the reaction is stirred 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 method of modified hydroxyapatite is specifically as follows:

[0043] Take fresh water hyacinth and dr...

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 wall coating for buildings. Background technique [0002] Wall coating is used for decoration and protection of building walls, making the building walls beautiful and tidy, and at the same time protecting the building walls and prolonging their service life. According to the classification of building walls, wall coatings include interior wall coatings and exterior wall coatings. Interior wall paint pays attention to decoration and environmental protection; exterior wall paint pays attention to protection and durability. In addition to its own decorative and protective functions, wall coatings are also developing towards colorful, fashionable, healthy and environmentally friendly trends. People hope that the decorative effect is beautiful, noble, elegant, romantic and warm; they also hope that the material itself is pollution-free, healthy and environmentally friendly, and has a...
