Embodiment 1

[0010] The invention is an improved mildew-proof and waterproof coating, which is made of the following raw materials in parts by weight:

[0011] 7 parts of ammonium dichromate, 2.3 parts of slag Portland cement, 1.4 parts of m-p-cresol, 2.8 parts of rare earth drier, 3.7 parts of polyisocyanate, 1.6 parts of alkylphenol polyoxyethylene ether phosphate, benzene 2.7 parts of ethylphenol polyoxyethylene ether polyoxypropylene ether and 2.2 parts of benzylnaphthalenesulfonic acid formaldehyde condensate dispersant.

Embodiment 2

[0013] The invention is an improved mildew-proof and waterproof coating, which is made of the following raw materials in parts by weight:

[0014] 5 parts of ammonium dichromate, 1.2 parts of slag Portland cement, 0.8 parts of m-p-cresol, 2.3 parts of rare earth drier, 2.5 parts of polyisocyanate, 1.2 parts of alkylphenol polyoxyethylene ether phosphate, benzene 1.5 parts of ethylphenol polyoxyethylene ether polyoxypropylene ether and 1.2 parts of benzylnaphthalenesulfonic acid formaldehyde condensate dispersant.

Embodiment 3

[0016] The invention is an improved mildew-proof and waterproof coating, which is made of the following raw materials in parts by weight:

[0017] 8 parts of ammonium dichromate, 2.7 parts of slag Portland cement, 1.6 parts of m-p-cresol, 3.5 parts of rare earth drier, 5 parts of polyisocyanate, 2.3 parts of alkylphenol polyoxyethylene ether phosphate, benzene 3.3 parts of ethylphenol polyoxyethylene ether polyoxypropylene ether and 2.9 parts of benzylnaphthalenesulfonic acid formaldehyde condensate dispersant.

[0018] Compared with the existing waterproof coating, the present invention has excellent waterproof and anti-seepage performance, and can form a breathable and hydrophobic film with a certain depth on the outer wall of the building to prevent the intrusion of water, and at the same time, it can also prevent the wall from mildew It is less affected by ultraviolet rays and has the characteristics of long service life and good durability. It can be applied to various bu...

Abstract

The invention discloses an improved mildew-proof and waterproof coating, which is prepared from the following raw materials in parts by weight: 5-8 parts of ammonium dichromate, 1.2-2.7 parts of slag Portland cement, and 0.8-1.6 parts of m-p-cresol , 2.3-3.5 parts of rare earth drier, 2.5-5 parts of polyisocyanate, 1.2-2.3 parts of alkylphenol polyoxyethylene ether phosphate, 1.5-3.3 parts of phenylethylphenol polyoxyethylene ether polyoxypropylene ether and 1.2-2.9 parts of benzyl naphthalenesulfonic acid formaldehyde condensate dispersant. Compared with the existing waterproof coating, the present invention has excellent waterproof and anti-seepage performance, and can form a breathable and hydrophobic film with a certain depth on the outer wall of the building to prevent the intrusion of water, and at the same time, it can also play the role of preventing mildew on the wall , is less affected by ultraviolet rays, has the characteristics of long service life and good durability, can be applied to various building bases, and is convenient for construction.

Description

technical field [0001] The invention relates to an improved mildew-proof and waterproof coating, which belongs to the field of building materials. Background technique [0002] Architectural waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reaction curing. . The anti-mildew and waterproof coating for building improvement is used outdoors and has been exposed to wind and sun for many years. Therefore, compared with indoor waterproof coatings, it needs stronger waterproof and anti-seepage capabilities, good color retention performance, and can resist ultraviolet radiation. . The current waterproof materials for building exterior walls have a short service life. After several years of wind and sun, peeling and other phenomena will occur. Repainting requires a lot of man...
