Description

  The present invention relates to a decorative wall surface in a building, a civil engineering structure, or the like.

Conventionally, a decorative film having a three-dimensional uneven pattern is formed on a wall surface of a building, a civil engineering structure, or the like. Such a concavo-convex pattern can be expressed by appropriately selecting the type of coating material to be used, the equipment at the time of painting, and the like.
For example, Patent Document 1 describes that an uneven pattern is formed on a painted surface using a thick film coating material mainly composed of a binder and a filler. Patent Document 2 describes that a pattern surface is formed by spraying sand on a dotted main material paint layer formed by applying a main material paint in a dotted pattern. Patent Document 3 describes that after applying a finish coating material, an uneven pattern is formed using a pattern pressing tool.

  However, if the wall surface having such a decorative film is exposed to the outdoors for a long time, it may be contaminated by the influence of rainfall, dust, etc., and the aesthetics of the corner may be impaired. In particular, the concave and convex portions tend to be easily contaminated.

Such a ratio is preferable in terms of manifesting the effects of the present invention.

In the form (a), since the piperidine compound is chemically bonded to the resin component, a polymerizable piperidine compound can be used. As such a compound, a compound having a piperidyl group and a polymerizable unsaturated double bond can be used. For example, 4- (meth) acryloyloxy-2,2,6,6-tetramethylpiperidine, 4- (meta ) Acryloyloxy-1,2,2,6,6-pentamethylpiperidine, 4- (meth) acryloylamino-2,2,6,6-tetramethylpiperidine, 4- (meth) acryloylamino-1,2, 2,6,6-pentamethylpiperidine, 4-cyano-4- (meth) acryloyloxy-2,2,6,6-tetramethylpiperidine, 4- (meth) acryloyloxy-1-methylcarbamoyloxy-2, 2,6,6-tetramethylpiperidine, 1- (meth) acryloyl-4- (meth) acryloylamino-2,2,6,6-tetramethylpipe Gin, 1- (meth) acryloyl-4-cyano-4- (meth) acryloylamino-2,2,6,6-tetramethylpiperidine, 4-crotonoyloxy-2,2,6,6-tetramethylpiperidine 4-crotonoylamino-2,2,6,6-tetramethylpiperidine, 1-crotonoyl-4-crotonyloxy-2,2,6,6-tetramethylpiperidine and the like.

Examples of such components include matting agents, thickeners, film-forming aids, leveling agents, wetting agents, plasticizers, antifreezing agents, pH adjusting agents, antiseptics, antifungal agents, and antialgal agents. Antibacterial agents, dispersants, antifoaming agents, adsorbents, fibers, crosslinking agents, ultraviolet absorbers, antioxidants, catalysts and the like can be mentioned.

What is necessary is just to select the coating method suitably so that a desired uneven | corrugated pattern may be formed when apply | coating the said coating | covering material on a base material. For example, a spray, a roller, a brush, a trowel, or the like can be used as the coating instrument. Of course, a plurality of these coating instruments may be used in combination. For example, after spray coating, an uneven pattern can be formed by various design rollers.
The coating amount of the coating material is preferably about 0.5 to 8 kg / m ^{2 in} terms of solid content.

The average primary particle diameter of silica is usually 1 to 200 nm, preferably 3 to 100 nm. Within this range, a plurality of silicas having different average primary particle sizes can be used in combination. When the average primary particle diameter of silica is larger than 200 nm, the specific surface area becomes small, and silanol groups are also reduced, so that the antifouling property becomes insufficient. When the average primary particle diameter is smaller than 1 nm, the silica itself becomes unstable, so it is not practical. In addition, the average primary particle diameter said here is a value measured by the light-scattering method.

The silica of the transparent coating (B) is preferably derived from a silica sol, and further derived from a water-dispersible silica sol having a pH of 5.0 or more and less than 8.5 (preferably 6.0 or more and 8.0 or less). Is more preferred.

In addition, alkoxysilane compounds other than the above silicate compounds, alcohols, glycols, glycol ethers, fluorine alcohols, silane coupling agents, polyoxyalkylene group-containing compounds, and the like can also be used.

  Various resins can be used as the resin component in the transparent coating (B). Specifically, for example, acrylic resin, urethane resin, vinyl acetate resin, silicon resin, fluororesin, acrylic vinyl acetate resin, acrylic urethane resin, acrylic silicon resin, and the like, one or more of these are used. it can. Such a resin component is preferably a water-soluble resin and / or a water-dispersible resin.

  The solid content weight ratio (silica: resin component) of silica and resin component in the transparent coating (B) is preferably 0.5: 1 to 5: 1, more preferably 0.8: 1 to 4: 1, Preferably it is 1: 1-3: 1. If it is such ratio, sufficient effect will be acquired in the pollution prevention effect and adhesiveness with a lower layer film, and the effect of the present invention will be exhibited stably.

  The transparent film (B) can be formed by applying and drying a coating material containing the above components. The covering material may contain various components other than the above components as long as the effects of the present invention are not significantly impaired. Such components include, for example, thickeners, film-forming aids, leveling agents, wetting agents, plasticizers, antifreeze agents, pH adjusters, antiseptics, antifungal agents, antialgae agents, antibacterial agents, dispersions Agents, antifoaming agents, crosslinking agents, ultraviolet absorbers, antioxidants and the like. However, it is desirable to avoid the use of a photocatalytic substance because it may cause a decrease in adhesiveness over time and discoloration of the pattern film.

What is necessary is just to apply this coating | covering material to the whole surface on a pattern film (A). As a coating instrument, well-known things, such as a brush, a roller, and a spray, can be used, for example. Coating with the amount of the coating material for forming the transparent film (B) is in terms of the solid content, preferably 0.1 to 50 g / ^{m 2,} more preferably 0.5 to 20 g / ^{m 2.}
