れらに塗布する塗料に関する。Detailed Description of the Invention [Industrial Application Field] The present invention provides durability such as weather resistance, stain resistance, water resistance, and frost damage resistance, as well as mold resistance, treated with a water-repellent θ oil agent made of a fluorine-containing silane compound. Concerning building materials with excellent properties. More specifically, the present invention relates to water- and oil-repellent cement-based joint fillers, ALC boards, slate boards, calcium silicate boards, slate boards, cement-based molded bodies, cement mortar, concrete bases, and paints applied thereto.

き起こす。In general, architectural base materials 1, such as ALC boards, cement mortar surfaces, concrete surfaces, slate boards, and silica boards, have high water absorption rates and are likely to stain and stain due to water absorption. Especially A.L.
C boards, slate boards, etc. are often painted for design purposes or to protect the board because their strength decreases due to water absorption, and they are rarely used unpainted. If the durability of the paint film on this painted surface is insufficient, deterioration will result in peeling, blistering, etc., which will cause not only the paint film but also the base to chip, fall off, and become brittle.

料を得ることができる。Water is involved in all of the causes of deterioration of building materials as described above, and in many cases, deterioration occurs through water. Therefore, by imparting water repellency to building materials, it is possible to obtain materials that can be used in locations where durability is required without changing the components of the materials themselves.

Even if the concentration of the fluorine-containing silane coupling agent is 0.01% by weight or less, sufficient water- and oil-repellent effects can be obtained by overcoating several times. If it is 20% by weight or more, uneven coating may occur or a long time will be required for drying. Furthermore, when applying the composition to a building material with a high water absorption rate, such as an inorganic material, it is preferable to repeat the application in multiple coats in order to provide a better water absorption prevention effect. Halogenated hydrocarbons are used as solvents.

The amine used here may be any of primary, secondary and tertiary amines, but -class amines are particularly effective. In the aqueous solution of these amines or acids, the trihalogenosilyl group or trialkoxysilyl group of the fluorine-containing silane compound is hydrolyzed by water to form a 1-lihydroxyl group, and polar groups present near the surface of the material (e.g. (hydroxyl group, carboxyl group, etc.) through hydrogen bonding or dehydration condensation to form chemical bonds and exhibit strong adsorption action.
