[0003] In order to meet people's needs, many functional latex paints have also appeared on the market. For example, the patent No. is CN111393941A. A kind of high-elastic environmental protection latex paint improves the elasticity of the coating film and solves the problem of cracks in the drying process and temperature changes; the patent No. A kind of antibacterial self-cleaning environment-friendly latex paint of CN112063211A has the problem of preventing bacteria and other microorganisms from multiplying and growing, and mildew spots on the wall are difficult to clean; a kind of mildew-proof latex paint whose patent number is CN111793396A solves the problems of poor water resistance, water absorption, whitening and mildew.
[0004] With the continuous improvement of living standards, people's requirements for decorative materials have also increased. There are many types of latex paints with different functions, which are not convenient for people to choose, and their performance cannot meet the needs. Nowadays, consumers are increasingly Under the premise of pursuing a low-carbon, environmentally friendly, and healthy living environment, if the traditional latex paint can be combined with the properties of stain resistance, waterproof, environmental protection, and decorative effects, it can achieve anti-condensation, and solve the problem of mildew and mildew in autumn and winter by reducing the temperature difference. In the rainy season, especially the basement is prone to condensation and mold problems, and it can also achieve thermal insulation performance, energy saving and environmental protection, and a comfortable and warm living environment. It will be one of the development trends of future decoration and decorative coatings

preparation example Construction
[0033] The preparation method of the anti-condensation heat preservation latex paint of the present invention specifically comprises the following steps:
[0034] Step 1: Add water into a container and start stirring, add bentonite;
[0035] Step 2: After the solution is uniform and thickened, add multifunctional additives, dispersants, defoamers, antibacterial agents and stir evenly;
[0036] Step 3: Mix titanium dioxide, mica powder, and heavy calcium, and disperse evenly;
[0037] Step 4: Add pure acrylic emulsion and silicone resin emulsion and mix well;
[0038] Step 5: Add insulation material and mix well;
[0039] Step 6: Add film-forming aids, antifreeze agents, and water repellents and stir evenly to obtain the finished anti-condensation and thermal insulation latex paint.
[0040] The heat insulating material is prepared as follows: uniformly mixing microbeads, nano silicon dioxide and airgel slurry in proportion to obtain the heat insulating material.

Abstract
The invention discloses an anti-condensation thermal insulation latex paint, which comprises a mixed emulsion formed of the pure acrylic emulsion and a silicone resin emulsion, and a thermal insulation material formed by combining microbeads, nanometer silicon dioxide and airgel slurry; The mixed emulsion accounts for 22-40% of the total mass of the anti-condensation coating; the heat insulating material accounts for 13-22% of the total mass of the anti-condensation coating. The anti-condensation and thermal insulation latex paint in the present invention adds a thermal insulation material formed by a combination of airgel, microbeads and nano-silicon dioxide to achieve the effect of thermal insulation, and at the same time, according to the anti-condensation mechanism, the coating lowers the The temperature difference between the surface temperature and the air temperature achieves the purpose of preventing condensation; and ceramic hollow microspheres are selected, which can achieve better heat insulation effect under the premise of ensuring a small thickness; pure acrylic emulsion and silicone resin are used The mixed emulsion combined with the emulsion, the silicone resin emulsion has air permeability, so that the moisture inside the concrete can penetrate, avoiding the hollowing and peeling of the coating, and improving the friction resistance of the coating.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-condensation and heat-retaining emulsion paint and a preparation method of the anti-condensation and heat-retaining emulsion paint. Background technique [0002] Since the birth of latex paint in the middle and late seventies of the 20th century, it has been one of the most widely used paints for daily decoration. Water-based latex paint is an environmentally friendly paint with water as the dispersion medium. It is a decorative paint with many advantages such as simple construction, various colors, environmental protection and health, rapid drying, water resistance of the paint film, and good scrub resistance. It can be used for interior and exterior wall decoration of villas, high-end residences, high-rise buildings, etc. [0003] In order to meet people's needs, many functional latex paints have also appeared on the market. For example, the patent No. is CN111393941A...
