Problems solved by technology

[0002] At present, there are many waterproof coatings on the market, but the main method is to add organic polymers or resins to achieve the waterproof effect. The waterproof effect of this coating is limited, because the surface of the coating is hydrophilic, and its surface is easy to absorb water and dirt, resulting in the use of the coating surface. Short life and mildew and discoloration, reducing service life

[0038] Preparation method of superhydrophobic coating:

[0039] Method 1, the paint is first mixed with paint additives and water, and then fully mixed with nano superhydrophobic emulsion.

[0040] The second method is to mix the paint with paint additives, alkaline additives and water, and then fully mix it with nanometer super-hydrophobic emulsion.

[0041] The third method is to pre-mix the paint with the nano-superhydrophobic emulsion, and at the same time pre-mix the paint additives with the alkaline additives and water, and finally mix the two pre-mixed mixtures together and fully stir them evenly.

[0042] After mixing well, it can be applied according to the normal method of painting paint, and it can show super-hydrophobic surface characteristics after it is completely dry.

[0043] After the hydrophobic coating is prepared, it can be applied according to the conventional coating method. After it is completely dry, the surface of the super-hydrophobic coating will ap...

Embodiment 1

[0058] Embodiment 1 (effective active substance content is 0.1%);

[0059] Mix 100 kilograms of paint with 20 kilograms of calcium stearate and 1 kilogram of calcium hydroxide powder and 30 kilograms of water, and then fully mix with 10 kilograms of nanometer superhydrophobic emulsion with a concentration of 1% until a mixture of homogeneous phase and suitable consistency is formed, Apply according to the method of normal paint brushing, and it will show the hydrophobic surface characteristics after it is completely dry.

Embodiment 2

[0060] Embodiment 2 (effective active matter content is 1%);

[0061] Mix 100 kg of paint with 10 kg of calcite powder, 3 kg of calcium stearate, 3 kg of slaked lime powder, 2 kg of sodium carbonate, and 20 kg of water, and then fully mix it with 19.7 kg of nano-superhydrophobic emulsion with a concentration of 6% until it is formed The mixture of homogeneous phase and suitable consistency can be applied according to the method of normal painting, and it can show super-hydrophobic surface characteristics after completely drying.

Abstract

The invention discloses a method for preparing a super-hydrophobic coating, which relates to a method for preparing the super-hydrophobic coating. The invention mainly aims to solve the problem of poor waterproof effect of the existing waterproof paint. The raw materials used in the method comprise a coating, a coating auxiliary agent, water and a nano super-hydrophobic emulsion, and the coating,the coating auxiliary agent, the water and the nano super-hydrophobic emulsion are mixed and uniformly stirred. The coating additive accounts for 1%-50% of the weight of the coating, the effective active matter of the nano super-hydrophobic emulsion accounts for 0.1%-20% of the total weight of the coating and the coating additive, the concentration of the effective active matter of the nano super-hydrophobic emulsion is 1%-70%, and the adding proportion of the water is the viscosity required when a conventional coating is brushed. An alkaline auxiliary agent can be added. The alkaline auxiliary agent accounts for 0.1-20% of the weight of the coating. The invention has the advantages that the coating has water-repellent, dirt-repellent and self-cleaning functions which are not possessed bycommon waterproof paint, and the surface is kept clean for a long time and is not easy to stain.

Description

Technical field: [0001] The invention relates to a method for preparing a superhydrophobic coating. Background technique: [0002] At present, there are many waterproof coatings on the market, but the main method is to add organic polymers or resins to achieve the waterproof effect. The waterproof effect of this coating is limited, because the surface of the coating is hydrophilic, and its surface is easy to absorb water and dirt, which leads to the use of the coating surface. Short life and moldy discoloration, reducing service life. Invention content: [0003] The technical problem to be solved by the present invention is to provide a method for preparing a superhydrophobic coating with good waterproof effect, water and dirt repelling and self-cleaning functions. [0004] The above-mentioned purpose is achieved in this way: the raw materials used are paint, paint additives, water, and nano-superhydrophobic emulsion, and the paint, paint additive, water, and nano-superhy...
