Problems solved by technology

Unlike the above-mentioned solvent-based coating agents, water-based coating agents have less health concerns even if volatilized solvents are inhaled, but compared with solvent-based coating agents, glossiness and durability are often insufficient, and there are still room for improvement

Embodiment 1

[0095] (1) Preparation of floor coating agent

[0096] 30% by mass of a silane coupling agent (manufactured by Shin-Etsu Chemical Co., Ltd.; KBM403) as the first component, and colloidal silica (manufactured by Nissan Chemical Co., Ltd.) as the second component; silica (average particle diameter 20-25nm) 40% by mass aqueous dispersion) 2.5% by mass (so the amount of silica is 1% by mass), as the third component, a fluorine-based surfactant (manufactured by AGC Seimi Chemical Co., Ltd.; Surflon S-211 ) 0.005% by mass, 1.5% by mass of phosphoric acid as the fourth component, and 67.495% by mass of water as the fifth component (including water in colloidal silica) were mixed to prepare the floor coating agent involved in Example 1. The composition is shown in Table 1.

[0097] For the floor coating agent involved in Example 1, the total amount of combustible substances in the floor coating agent (the total amount of combustible substances specified in 4 of Article 9 of the Fire ...

Embodiment 2

[0120] (1) Preparation of floor coating agent

[0121] As the first component, 10 mass % of alkoxysilane and 20 mass % of a silane coupling agent (manufactured by Shin-Etsu Chemical Co., Ltd.; KBM403) were used, and as the second component, colloidal silica (Nissan Chemical Co., Ltd.) was used. Manufacture: 40% by mass aqueous dispersion of silica (average particle diameter 20-25nm)) 50% by mass (therefore the amount of silica is 20% by mass), as the fifth component, use 48.495% by mass of water (including colloid water in silica), and the coating agent for floors related to Example 2 were prepared in the same manner as in Example 1. The composition is shown in Table 1.

[0122] About the floor coating agent concerning Example 2, the total amount of combustibles, solid content, flash point, and ignition point were calculated similarly to Example 1, respectively. The results are shown in Table 1.

[0124] A coating film was formed in ...

Embodiment 3

[0130] (1) Preparation of floor coating agent

[0131] As the second component, 30% by mass of colloidal silica (manufactured by Nissan Chemical Industries, Ltd.; 40% by mass aqueous dispersion of silica (average particle diameter: 20 to 25 nm)) was used (therefore, the amount of silica was 12 % by mass), as the fourth component, 0.5 mass % of phosphoric acid was used, and as the fifth component, 57.495 mass % of water (including water in colloidal silica) was used, and all were prepared and implemented in the same manner as in Example 1. The coating agent for floors involved in Example 3. The composition is shown in Table 1.

[0132] About the floor coating agent concerning Example 3, the total amount of combustibles, solid content, flash point, and ignition point were calculated similarly to Example 1, respectively. The results are shown in Table 1.

[0133] (2) Coating of floor materials

[0134] A coating film was formed in the same manner as in Example 1 except that t...

Abstract

Provided is a floor coating agent that can be used in a high safety environment, the floor coating agent having exceptional glossiness and durability. The present invention comprises a silane couplingagent and / or an alkoxysilane as a first component, silica and / or a metal oxide as a second component, a leveling agent as a third component, a curing catalyst as a fourth component, and water as a fifth component. Relative to the total mass of the first to fifth components, the ratio of the first component is 5 to 70 mass%, the ratio of the second component is 1 to 50 mass%, the ratio of the third component is 0.001 to 1 mass%, the ratio of the fourth component is 0 to 7 mass%, the ratio of the fifth component is the remainder, and relative to the gross mass of the floor coating agent, the ratio of the total mass of the first to fifth components is 95 to 100 mass%.

Description

technical field [0001] The present invention relates to a floor coating agent, a floor coating method, and a floor structure manufacturing method. Background technique [0002] In addition to the past, for the purpose of maintaining the appearance of the floor and antifouling, the operation of coating the surface of the floor with a coating agent has been carried out, and various coating agents for this operation have been developed (for example, refer to Patent Document 1, Patent Document 2 ). [0003] However, many commercially available coating agents containing the coating agents disclosed in Patent Documents 1 and 2 above are so-called solvent-based coating agents using volatile organic solvents such as alcohols as solvents. Although these solvent-based coating agents are excellent in gloss and durability, there is a concern that workers may suffer health damage by inhaling volatilized solvents during handling. This phenomenon can be prevented to some extent by perfor...
