[0010] The present invention is a mildew-proof and waterproof coating for exterior walls, which is made of the following raw materials in parts by weight:

[0011] 7 parts of ammonium dichromate, 2.3 parts of toluene diisocyanate, 1.4 parts of m-p-cresol, 2.8 parts of rare earth drier, 3.7 parts of polyvinyl chloride, 1.6 parts of alkylphenol polyoxyethylene ether phosphate ester, polystyrene ethylphenol 2.7 parts of oxyethylene ether polyoxypropylene ether and 2.2 parts of benzylnaphthalenesulfonic acid formaldehyde condensate dispersant.

Embodiment 2

[0013] The present invention is a mildew-proof and waterproof coating for exterior walls, which is made of the following raw materials in parts by weight:

[0014] 5 parts of ammonium dichromate, 1.2 parts of toluene diisocyanate, 0.8 parts of m-p-cresol, 2.3 parts of rare earth drier, 2.5 parts of polyvinyl chloride, 1.2 parts of alkylphenol polyoxyethylene ether phosphate ester, polystyrene ethylphenol 1.5 parts of oxyethylene ether polyoxypropylene ether and 1.2 parts of benzylnaphthalenesulfonic acid formaldehyde condensate dispersant.

Embodiment 3

[0016] The present invention is a mildew-proof and waterproof coating for exterior walls, which is made of the following raw materials in parts by weight:

[0017] 8 parts of ammonium dichromate, 2.7 parts of toluene diisocyanate, 1.6 parts of m-p-cresol, 3.5 parts of rare earth drier, 5 parts of polyvinyl chloride, 2.3 parts of alkylphenol polyoxyethylene ether phosphate, styrene ethyl phenol poly 3.3 parts of oxyethylene 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 b...

Abstract

The present invention discloses an exterior wall anti-mildew waterproof coating material, which is prepared from the following raw materials by weight: 5-8 parts of ammonium dichromate, 1.2-2.7 parts of toluene diisocyanate, 0.8-1.6 parts of m-cresol and p-cresol, 2.3-3.5 parts of a rare earth drier, 2.5-5 parts of polyvinyl chloride, 1.2-2.3 parts of polyoxyethylene alkyphenol phosphorate, 1.5-3.3 parts of phenethyl phenol polyoxyethylene ether polyoxypropylene ether, and 1.2-2.9 parts of a benzyl naphthalene sulfonic acid formaldehyde condensation compound dispersing agent. Compared with the existing waterproof coating material, the exterior wall anti-mildew waterproof coating material of the present invention has excellent water resistance impermeability, can form an air-permeable hydrophobic film with a certain depth on the building exterior wall so as to prevent moisture from intrusion and further provide an effect of wall mildew resistance, has characteristics of less influence by ultraviolet light, long service life, good durability and easy construction, and can be applied for a variety of building sites.

Description

technical field [0001] The invention relates to a mildew-proof and waterproof coating for exterior walls, 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. . Because the anti-mildew and waterproof coatings on the exterior walls of buildings are used outdoors, they are exposed to wind and sun for many years. Therefore, compared with indoor waterproof coatings, they need stronger waterproof and anti-seepage capabilities, good color retention performance, and can resist ultraviolet rays. . 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...
