Embodiment 1

[0019] Put 30 parts of propylene emulsion, 5 parts of styrene-butadiene emulsion, 10 parts of kaolin, and 0.5 parts of molybdenum disulfide into the reaction kettle, and stir evenly at 70°C for 40 minutes. During the stirring process, an auxiliary power of 1500w Ultrasonic vibration, that is, the basic material;

[0020] Wash 50 parts of the root of the sheep's trotter, dry it and crush it to the nanometer level, put the powder of the root of the sheep's trotter into 5 parts of the sodium hydroxide solution with a pH value of 7.5, and stir evenly under the assistance of microwaves. The stirring time is 30 minutes, and the stirring is completed Afterwards, centrifuge through a centrifuge, take the filtrate, mix the obtained filtrate with 3 parts of soybean protein, and stir evenly for 5 minutes to obtain the extract;

[0021] Mix the obtained extract with 10 parts of latex and 0.5 parts of water-retaining agent, and stir evenly at 50°C. The temperature is controlled by heating ...

Abstract

The invention provides a mildew-proof and waterproof coating and a preparation method thereof, relating to the field of coatings. Prepared from the following raw materials in parts by weight: 30-40 parts of propylene emulsion, 5-8 parts of styrene-butadiene emulsion, 10-15 parts of kaolin, 0.5-1 part of molybdenum disulfide, 0.5-1 part of water-retaining agent, 3-5 parts of ingredients Membrane aid, 3-5 parts of soybean protein, 5-10 parts of sodium hydroxide solution, 10-20 parts of latex, 50-60 parts of sheep's trotter root. The invention provides a mildew-proof and waterproof coating and a preparation method thereof, which can effectively prevent mildew and sterilize and have a long service life.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a mold-proof and waterproof coating and a preparation method thereof. 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 coatings for building improvement are used outdoors and are exposed to wind and sun for many years. Therefore, compared with indoor waterproof coatings, they need stronger waterproof and anti-seepage capabilities and better color retention. 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 manpower and material resources. Improved...
