Formula and preparation method of multifunctional damp-proof coating

Abstract

The invention discloses a formula and a preparation method of a multifunctional damp-proof coating, which relate to the technical field of air purification and air humidity reduction. The coating comprises the following components by weight: 20%-30% of 310TS emulsion, 5%-15% of silica solution, 10%-20% of water, 10%-20% of diatomite filter aid, 10%-20% of wollastonite acicular powder, 5%-10% of light calcium carbonate, 5%-10% of zeolite, 0.8%-1% of negative ion element, 0.5%-2.5% of wetting agent 188A, 0.5%-2.5% of levelling agent 2020, 0.5%-2.5% of coalescing agent alcohol ester-12, 0.5%-1.5% of anti-freezing agent ethylene glycol, 0.5%-2.5% of thickener 935, 0.1%-0.5% of defoamer NXZ, 0.1%-1.0% of dispersing agent 8045, and 0.2%-0.8% of mildew preventative. The preparation method of the coating comprises the process of: uniformly mixing a solid material and a liquid material according to the proportion of 10:7.5; adding the mixed materials into a mixer; mixing and kneading the materials for 30 minutes at a low temperature; and finishing mixing till the coating is greasy. With the formula and the preparation method of the multifunctional damp-proof coating disclosed by the invention, the energy is saved, the environment is protected, energy consumption is reduced, and low-carbon emission reduction is realized; the coating can well absorb condensation water so as to reduce air humidity, and can also absorb harmful gas such as benzene; and the product is unique, the formula is novel, and the coating is suitable for buildings and power equipment, etc.

Description

Technical field: [0001] The invention relates to the technical field of air purification and reduction of air humidity, in particular to a formula of a multifunctional moisture-proof coating and a preparation method thereof. Background technique: [0002] In recent years, with the modernization of living room decoration, indoor air quality is often neglected. Indoor air pollution has become a common concern of all countries in the world. Environmental experts have listed indoor air pollution as one of the five most harmful factors to human health. Research by American experts shows that indoor air pollution is 2-5 times more serious than outdoor air, and can reach 100 times in special cases. The negative ion concentration in air-conditioned closed room is only 0-25 / cm3. The World Health Organization stipulates that the standard concentration of negative ions in fresh air is 1000-1500 / cm3. [0003] In addition, in autumn and winter or mildew season, when the temperature of...

Problems solved by technology

In some cases, excessive humidity on the surface of the building may cause serious consequences or cause great harm, because when water droplets are generated in the building, the water droplets will pollute the inner surface of the living room and the items stored in the room, etc., and may cause mildew , accelerate the destruction of building materials, and have a great impact on the use and function of buildings

Especially for industrial buildings, it not only has a great impact on the structure of the factory building and the operators in the factory building, but also may cause rust and mildew of the produced products, and thus reduce the quality of the products and cause adverse consequences

For computer rooms, precision instruments, instrument rooms and other high-grade buildings with strict indoor environmental function requirements, if water vapor condenses and drips, the problem will become more serious, and may even lead to calculation failures, test However, it is regrettable that such buildings with high requirements are especially prone to water droplets inside when the temperature is low and the humidity is high.
