Description

Technical Field [0001] The present invention relates to a ceramic non-slip coating composition,

The present invention relates to a ceramic-based non-slip coating composition and a method of applying the same, and more particularly, to a ceramic-based non-slip coating composition which is applied to the surface of a structure to protect the surface, A non-slip coating composition, and a construction method for increasing the physical strength of a building structure and a civil engineering structure (steel or concrete) using the same.

In general, the coating is to coat the surface of the material with a coating through a coating to complement the surface properties. Such a coating has conventionally been widely used for a long time for the purpose of preventing scratches and corrosion of the surface, and is now being used for the purpose of imparting various functions such as antistatic, antibacterial and electromagnetic shielding through coating.

On the other hand, such a coating is made by an organic coating agent such as an ultraviolet curable oligomer / acrylic monomer coating, a silicon coating, a polyurethane coating, and an inorganic coating agent mainly using ceramics or silicon.

However, since the organic coating agent has flexibility and toughness and is excellent in moldability, it has a low mechanical strength and low heat stability. The inorganic coating agent shows excellent transparency, surface hardness, scratch resistance and heat resistance However, it requires a lot of cost and time to manufacture, has a problem that the shrinkage is severe and the flexibility is not sufficient and cracks are generated severely during processing.

Therefore, it is possible to complement the physical properties of inorganic and organic materials by using composite materials such as inorganic coatings instead of unified coatings such as organic coatings and inorganic coatings.

However, in this case, since it is difficult to uniformly disperse the inorganic material, it has been difficult to apply it to the case where excellent optical characteristics and fine physical properties are required. Recently, in order to solve the above problems, an organic / inorganic hybrid Type, and various research results have been reported.

For example, Japanese Patent Publication No. 1998-247702 discloses a hybrid coating agent using an organosilicon compound and a titanium oxide compound. In Japanese Patent Publication No. 1990-264902, a hard coating agent composed of organic silicon, a cerium oxide compound, and a titanium oxide compound . However, these have problems that the weather resistance of the coating film is poor and discoloration or the like occurs.

In addition, many research results have been reported, such as a method of producing an organic or inorganic hybrid compound using a sol-gel method using an organic metal alkoxide with water and a catalyst (U.S. Patent Nos. 6,054,253, 5,378,79, and European Patent No. 565,044) However, the present invention does not satisfy the physical properties required for the coating film at present.

On the other hand, when the floor of the building or the parking lot of the building is mainly constructed of concrete, slip phenomenon frequently occurs on the concrete floor surface, which causes a safety accident of the pedestrian and a contact accident due to slipping of the vehicle.

In order to solve the above-mentioned problems, the conventional anti-slip material is applied, but it has a limitation in service life and has a problem of being easily contaminated.

In addition, the anti-slip material mixed with silica, such as epoxy and polyurethane, was applied to the bottom surface. However, due to the settling phenomenon of silica sand, the epoxy or urethane was firstly applied. There was also construction problem to be applied.

In addition, it is difficult to automate the construction of an additional anti-slip agent such as silica or the like after the epoxy or urethane is applied, and the anti-slip material such as silica sand can not be uniformly applied, In addition, the particle shape of the silica sand is angled, so that it is easy to pollute and the washing of the pollution is not easy. When the pedestrian falls, there is a problem that the skin is damaged (abrasion).

Accordingly, it is possible to overcome the limitations of the conventional coating film, to penetrate the concrete surface, to improve the mechanical properties, to solve the problems of adhesion failure, water pocket, lifting, etc. of the existing coating film, There is a continuing need for a coating composition having excellent properties such as excellent durability, anti-abrasion resistance, impact resistance, solvent resistance, chemical resistance and stain resistance.

Accordingly, one aspect of the present invention is to provide a non-slip agent which is free of dust generation during the construction and which is free from dust, and which is excellent in durability, abrasion resistance, impact resistance, water resistance, Which is superior in physical and chemical properties such as chemical resistance and excellence, and (3) has a long life and is easy to maintain.
