SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a waterproof coating, a waterproof coating and a waterproof coating, Waterproofing and water repellent to effectively prevent contamination by maximizing the dispersibility of static electricity even when a small amount of nano-sized ceramic powder is used, It is intended to provide environmentally friendly paints.
The antifouling, water-repellent and water-repellent environment-friendly paint according to the present invention comprises 100 parts by weight of silicone; 15 to 25 parts by weight of a urethane foam coated with a ceramic composition; 5 to 8 parts by weight of a dispersant; 25 to 35 parts by weight of a titanate polymer resin composition; 15 to 22 parts by weight of an aluminum powder; 2 to 8 parts by weight of a light stabilizer; 2 to 5 parts by weight of an anti-flow agent; 3 to 5 parts by weight of a sedimentation inhibitor; 10 to 25 parts by weight of a filler; 6 to 15 parts by weight of an antioxidant composed of zinc powder,
The urethane foam coated with the ceramic composition is formed by coating a urethane foam with a ceramic composition composed of a ceramic powder having a particle size of 300 nm to 500 nm and an epoxy,
The ceramic powder is used in an amount of 30 to 40 parts by weight based on 100 parts by weight of the silicone, and the epoxy is used in an amount of 10 to 20 parts by weight based on 100 parts by weight of the ceramic powder.
According to the present invention, an antifouling and water-repellent and water-repellent eco-friendly paint enables heat resistance and oxidation resistance, water repellency and water resistance through silicon, and the surface of the paint layer is formed as concavo- In addition, the ceramic is coated on the surface of the urethane foam, and even if only a small amount of the ceramic is used in small amounts, the electrostatic dispersion effect is excellent. Therefore, the fine dust is prevented from adhering to the surface of the coating layer, And the moisture is slid off, and the coating layer and the object to be coated (such as a civil engineering structure such as a soundproof wall, a road facility structure such as a traffic safety sign, electric and electronic parts, etc.) There is an effect of preventing damage.
In addition, it is possible to use a ceramic having a small particle size to be discarded, and a small amount of ceramic is used to reduce the cost of disposing ceramics and reduce the production cost.
In addition, since the urethane foam prevents the loss of the ceramic, the effect of the ceramic can be derived for a long period of time, and as a result, the durability of the material to be coated is improved.
The antifouling and water repellent and water-repellent eco-friendly paints according to the present invention can be applied to various paints such as silicone (one-component type and two-component type), urethane foam coated with ceramic composition (ceramic powder and liquid epoxy), dispersant, light stabilizer, , A filler, and an antioxidant, and a pigment may be added.
Silicone has various properties such as heat resistance, oxidation resistance, water repellency, water resistance, electrical insulation, and both one-component and two-component.
The ceramic powder of the ceramic composition is composed of basic oxides and serves to buffer the acidic environment and to increase the heat resistance, abrasion resistance, chemical resistance, hardness and the like of the coating layer. It is easily dried at room temperature to form a coating layer. Ceramic powder is used as a ceramic composition together with epoxy. That is, the ceramic composition is composed of a ceramic powder and an epoxy.
The present invention is advantageous in that the coating layer is formed on the surface of the concavo-convex surface through the ceramic powder and the coating layer and the object to be coated are protected (noxious gas neutralization, humidity control, etc.) For example, 300 nm to 500 nm. In other words, the particulate ceramic powder forms fine irregularities on the surface of the coating layer to prevent contamination by fine dust and deteriorates the adhesion force of other deposits, thereby preventing the surface of the coated object from being contaminated. do. When the ceramic powder is mixed with less than 30 parts by weight, the surface of the coating layer can not be formed into irregularities and other effects are weak. When the amount exceeds 40 parts by weight, the ceramic powder is not harmonized with other materials and the function of the coating layer is weak. Can be used.
The present invention is characterized in that a urethane foam coated with a ceramic composition is used in which the ceramic powder is coated on a three-dimensional urethane foam so as to perform the above-described function even if the ceramic powder is used in a small particle size.

The dispersing agent is used to disperse the materials and prevent the re-agglomeration through the use of silicone and non-silicone dispersants. By dispersing them in a uniform distribution, uniform strength and stain resistance of the coating layer can be expressed, If the mixing range is outside the mixing range of 8 parts by weight, the dispersing effect is weak and the aggregation of the materials can not exhibit uniform strength and stain resistance, and there is no great effect on dispersion.
The titanate polymer resin blend is a combination of a titanate and a polymer resin, and functions as a catalyst. Less than 25 parts by weight of the titanate polymer resin binder may cause peeling of the coating layer due to poor adhesion of the coating layer. When the amount exceeds 35 parts by weight, It has a photocatalytic characteristic that decomposes and decomposes organic matter by absorbing visible light, thus securing a safe residential environment.
The aluminum powder is used for reinforcing the strength of the coating layer and for preventing the penetration of contaminants. Less than 15 parts by weight of the aluminum powder may penetrate the contaminants, and when it exceeds 22 parts by weight, excessive use may cause troubles with other materials.
The light stabilizer is used to prevent deterioration (change) of the coating layer caused by UV, and a known base product is used, and 2 to 8 parts by weight of the light stabilizer is mixed for the purpose of stabilizing the light while preventing changes in physical properties of the coating.
The flow inhibitor is used for coating workability of the paint. When less than 2 parts by weight, the flow can not be blocked and the loss of the paint is large. When the amount is more than 5 parts by weight, the viscosity of the materials is high. The anti-flow agent is preferably synthetic polyamide wax.
The anti-settling agent prevents the settling of the materials to form the coating layer with uniform properties. If the anti-settling agent is out of the range of 3 to 5 parts by weight, the effect of preventing the settling is weak and the settling prevention is not greatly changed. The specific material name is omitted.
Fillers are made of at least one material such as flooring materials (which can be replaced with fly ash as a thermal power plant material), calcium carbonate, blast furnace slag, etc. (use of ready-made products but not limited to numerical values) And 10 to 25 parts by weight are used for the impact resistance of the layer. The filler is mixed at various ratios such as the same ratio when two or more are mixed.
The antioxidant is preferably a zinc powder which prevents oxidation of the metal substrate by air, water and carbon dioxide and prevents oxidation of the metal substrate by oxidation prior to the metal substrate. The antioxidant may have the same particle size as that of the ceramic powder Of course, it is not limited to this particle size. When the amount is less than 6 parts by weight, the antioxidant effect is weak. When the amount is more than 15 parts by weight, the antioxidant effect is not greatly different.
