Embodiment

[0093] The features of the present invention will be more clearly described below with reference to examples.

[0094] (Manufacture of surface treatment fluid)

[0095] The following raw materials were mixed in the weight ratio shown in Table 1 by a common method, and surface treatment liquids 1-9 were produced.

[0096] Alkoxysilane compound 1: Hexyltrimethoxysilane (condensation degree 1)

[0097] Alkoxysilane compound 2: Hexyltriethoxysilane (condensation degree 1)

[0098] Alkoxysilane compound 3: Butyltrimethoxysilane (condensation degree 1)

[0099] Alkoxysilane compound 4: Hexyltrimethoxysilane (condensation degree 3)

[0100] Alkoxysilane compound 5: Hexyltrimethoxysilane (condensation degree is 6)

[0101] Solvent 1: a mixture of saturated aliphatic hydrocarbons with 9 or more carbon atoms

[0102] Solvent 2: Aliphatic hydrocarbon solvent (containing 30% by weight of aromatic hydrocarbon)

[0103] Solvent 3: aromatic hydrocarbon solvent (aromatic hydrocarbon 100...

Embodiment 1

[0155] For the test base material composed of cement mortar at the joint part and loess-colored porcelain tiles at the tile part, apply 80g / m2 to the entire surface 2 After spraying the required amount of surface treatment liquid 1, let it dry for 1 hour under the standard state (temperature is 23°C, relative humidity is 50%), and then apply 80g / m2 to the entire surface again 2 Spray the same surface treatment solution 1 in the required amount. Thereafter, it was allowed to dry for 24 hours in a standard state. The following tests were carried out on the test panels obtained by the above method. The results are shown in Table 2. In Example 1, good results were obtained in every test.

[0156] decorative

[0157] The appearance state of the painted tile portion was observed. There was no abnormality during drying and no change in texture and gloss after drying as "A", and a 3-level (A>B>C) evaluation was performed.

[0158] Anti-water absorption

[0159] The test panel w...

Embodiment 2

[0165] Except having used the surface treatment liquid 2 instead of the surface treatment liquid 1, it tested by the same method as Example 1. The test results are shown in Table 2. In Example 2, good results were obtained in every test.

Abstract

A simplified method in which in the coating of a porous inorganic material, there can be imparted excellent finish, water absorption preventing capability, etc.; and a simplified method in which there can be applied an excellent water absorption preventing performance, antifouling property, etc. onto ceramic tile surfaces while ensuring exertion of the existing characteristics of tile surfaces. There is disclosed a method of coating including the step of coating a surface of inorganic material with a surface treating liquid (A), characterized in that the surface of inorganic material contains a porous inorganic material, and that the surface treating liquid (A) contains 0.1 to 50 wt.% of alkoxysilane compound and 50 to 99.9 wt.% of solvent, and that the alkoxysilane compound contains 90 wt.% or more of alkylalkoxysilane compound of 2 or less condensation degree wherein the alkyl has 3 to 12 carbon atoms while the solvent contains 90 wt.% or more of aliphatic hydrocarbon.

Description

technical field [0001] The present invention relates to a coating method for porous inorganic materials such as concrete and cement mortar; in addition, the present invention also relates to a coating method for ceramic tile surfaces used for exterior decoration of buildings and the like. Background technique [0002] In the past, porous inorganic materials such as concrete and cement mortar, which are the base materials of buildings and civil structures, have been widely used to apply permeable water-absorbing anti-absorbing materials to impart water-absorbing properties and improve durability. [0003] The permeable anti-water absorption material is a waterproof layer formed by soaking in porous inorganic materials. Therefore, by coating this permeable anti-water absorption material, it is possible to block the water and carbon dioxide that infiltrate into the substrate from the outside, prevent the decrease in strength caused by the neutralization of the substrate, and fu...
