Embodiment 1

[0052] A waterproof coating. The waterproof coating is made of the raw materials shown in Table 1. The weight unit of the raw materials is kg, wherein the wetting agent is composed of monolauryl phosphate, soybean lecithin, and octylphenol polyoxyethylene ether. The weight ratio of lauryl phosphate, soybean lecithin, and octylphenol polyoxyethylene ether is 1:2:1.5; the dispersant is composed of 2-amino-2-methyl-l-propanol, vinyl triethoxy 2-amino-2-methyl-l-propanol, vinyltriethoxysilane, and sodium lauryl sulfate in a weight-to-number ratio of 1:1:1.2; the crosslinking agent Composed of Dicumyl Peroxide, N-Hydroxyethylacrylamide, 1,4-Butanediol Diacrylate, Dicumyl Peroxide, N-Hydroxyethylacrylamide, 1,4-Butanediol The ratio by weight of diacrylate is 1:1:1.5.

[0053] The average pore size of activated carbon is 60nm, the particle size range of activated carbon is 60-80μm, the average pore size of zeolite is 3nm, the particle size range of zeolite is 40-50nm, and the partic...

Embodiment 2-3

[0060] Example 2-3: a waterproof coating, the difference from Example 1 is that the raw materials of the waterproof coating are shown in Table 1.

[0061] The raw material of the waterproof coating of table 1 embodiment 1-3

[0062]

[0063]

Embodiment 4

[0065] A waterproof coating, the difference from Example 1 is that the ratio of monolauryl phosphate, soybean lecithin, and octylphenol polyoxyethylene ether is 1:3:1.5.

Abstract

The application relates to the field of architectural coatings, and specifically discloses a waterproof coating and a preparation method thereof. The waterproof coating is made of the following raw materials in parts by weight: 30-40 parts of water; 20-25 parts of silicone emulsion; 10 parts of styrene-butadiene emulsion ‑15 parts; silicone acrylic emulsion 4‑8 parts; propylene glycol 0.2‑0.4 parts; sepiolite powder 6‑10 parts; bentonite 1‑2 parts; diatomite 2‑4 parts; wetting agent 0.4‑0.6 parts; preservative 0.1-0.2 parts; 0.2-0.4 parts of dispersant; 0.1-0.2 parts of thickener; 1.8-2.5 parts of film-forming aid; 0.1-0.2 parts of pH regulator; 6-8 parts of activated carbon; 2-4 parts of zeolite. The coating film formed by the paint of the present application has the effect of waterproof and breathable, which can prevent water molecules from entering the coating film, and at the same time allow gas to enter the coating film, thereby purifying the air.

Description

technical field [0001] The application relates to the field of architectural coatings, more specifically, it relates to a waterproof coating and a preparation method thereof. Background technique [0002] Building leakage is a key factor affecting the durability and service life of building structures, and it will bring people personal safety hazards, property losses and inconvenience to life. The quality of building waterproofing projects directly affects the normal use and life of buildings and structures, and waterproof materials are an important factor affecting waterproofing projects. Waterproof coating refers to a coating formed by coatings that can prevent rainwater or groundwater from seeping. Waterproof coatings can be divided into emulsion type, solvent type, reactive type and modified asphalt according to the state and form of the coating. [0003] A wall paint for absorbing peculiar smell is disclosed in the related art, which includes: 35%-50% of film-forming s...
