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 mould-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 portland blast furnace slag cement, 0.8-1.6 parts of M-and P-cresols, 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 ethyl phenyl-phenol-polyoxyethylene polyoxypropylene ether and 1.2-2.9 parts of benzyl-naphthalene sulfonic acid formaldehyde condensate dispersing agent. Compared with the existing waterproof coating, the improved mould-proof and waterproof coating has excellent waterproof and anti-permeability performances, can form a certain depth of ventilating hydrophobic film on an exterior wall of a building, can prevent invasion of water, simultaneously can play a mould-proof function on the wall body, has the characteristics of being small in ultraviolet effect, long in service life, good in durability and convenient to construct, and can be applicable to a plurality of construction sites.

Description

Technical field [0001] The invention involves a improved mildew -proof waterproof coating, which is the field of building materials. Background technique [0002] Building waterproof coating is a viscous liquid polymer synthetic material with a fixed -shaped shape at room temperature. After coating, the volatilization of the solvent or the evaporation or reaction of the water can form a tough waterproof coating film material on the surface of the grass level.EssenceBecause the improved mildew -proof waterproof coatings are used outdoors, the wind and sun exposure throughout the year, so compared with the indoor waterproof coatings, it requires a stronger waterproof and penetration capacity, good color preservation performance, and can resist ultraviolet rays to irradiation of ultraviolet raysEssenceThe current service life of the exterior wall waterproof material of the building is short. After several years of wind, peeling will occur. Re -painting requires a lot of manpower and...
