Description

Detailed Description of the Invention The present invention provides a paint that prevents embedding and efflorescence on walls, floors, ceilings, and other surfaces to which an inorganic or organic coating material mixed with a colorant is applied as a top coat. The gist of the present invention relates to an improvement in the construction method of preventing embedding and efflorescence of a surface coated with a colored coating material using this coating material. This is a coating for preventing embedding and efflorescence on the surface to which a colored decorative coating material is applied, which is made by mixing 0.51 or more silicone resin oil or liquid paraffin with highly transparent mineral oil such as kerosene or light oil.

The second invention of the present invention is an inorganic or organic colored decorative coating material mixed with a coloring agent such as a pigment as a top coat on a coating surface such as a wall, floor, or ceiling coated with ordinary cement mortar or the like. Immediately after application, apply 0.0% of silicone resin oil or fluid glossy rough fine to highly transparent mineral oils such as kerosene and light oil with a boiling point of 60°C or higher when not dry.
Wrapping the coated surface of a colored decorative paint containing 5% or more, spraying and distributing an efflorescence prevention paint, immediately applying a handle using a handle tool such as a bell or roller, and immediately after applying the handle. This is an efflorescence-preventing construction method for a surface coated with a colored decorative coating material, which is characterized by repeating the same embedding and spraying of the efflorescence-preventing paint.

In general, it is widely practiced to apply synthetic resin-based colored decorative coating materials as a top coat to walls, floors, ceilings, and other surfaces that have been coated with ordinary coating materials such as cement mortar. The water-soluble alkaline components contained in the cement mortar applied to the ground may erode the topcoat, resulting in unsightly inclusions on the surface of the topcoat, and efflorescence still remains on the surface. There are fatal defects such as cloudy contamination, and there is a strong need to prevent this.

Essentially, inorganic colored decorative coating materials have the advantage of good weather resistance and excellent compatibility with the underlying coating material, but they have a problem with coloring as a decorative coating material, so they are not widely used. I haven't. The most common method for coloring inorganic colored cosmetic coating materials was, for example, mixing inorganic pigments with white cement, but the coating material could stick to the application tools during construction and roller application. Since patterning work becomes difficult, it is recommended to soak the tool in water to make it easier to mix lines, or attach a sponge to the roller and soak it with water or a release agent solution to prevent the coating material from sticking to the roller. However, it is not possible to prevent the above-mentioned kneading water, the solution applied to the rollers, the embossment caused by water, and the efflorescence phenomenon that occurs in cold weather such as winter, and therefore their widespread use is hindered and the rice I think it depends on the situation.

It has traditionally been considered extremely difficult to resolve the efflorescence phenomenon.
Although efflorescence itself is a phenomenon caused by internal factors in the cement-based coating material, the occurrence of efflorescence is said to be significantly influenced by external environmental conditions.

3- Also, the cause of embedding on the surface of the decorative coating material is that the release agent solution and water are not uniformly applied to the surface of tools such as rollers, resulting in uneven wiring, but the main cause is The main cause is the precipitation of fine particles of colored decorative coating materials due to the use of water, and this is due to the precipitation of fine particles being accelerated by the water and mold release agent solution used in handle tools. . In other words, the presence of water or mold release agent solution added during patterning may promote the formation of embeddings due to the precipitation of fine particles and the efflorescence phenomenon in cold seasons such as winter, which may even make it difficult to use during the winter. In view of the above-mentioned problems, the present invention has been developed by applying an inorganic colored decorative coating material, such as colored cement, mortar, dolomite, Norastar, lime, or plaster, onto a base coated surface to make the surface smooth or otherwise desired. Immediately after finishing the surface, while it is still wet, a paint made by uniformly mixing an appropriate amount of silicone resin oil or liquid paraffin with mineral oil is sprayed on the surface, and immediately after the patterning is applied, the spraying and spraying of the same paint is repeated again. By doing so, it is possible to prevent the colored decorative coating material from coming into contact with the outside and from depositing on the surface, thereby preventing the occurrence of embedding.

Spray the coating and efflorescence prevention paint of the present invention, which is made by mixing an appropriate amount of rough-in with mineral oil and a silicone resin oily liquid, on the painted surface coated with a handle of a roller handle. When spraying, this paint has a specific gravity that is lighter than the colored decorative coating material, the coloring agent, the mixing water of the coating material, and other water content, and immediately rises to the surface after spraying and spreads to the surface side of the colored cosmetic coating surface. An oil film will form, and immediately after wrapping, spraying the anti-efflorescence paint, and attaching the handle,
By repeating the spraying and spreading of the same paint again, the formation of an oil film on the surface side is further reinforced, and by forming a special oil film on the surface where the cosmetic coating material is applied,
The oil film formed on the surface suppresses the formation of embedding and efflorescence due to precipitation of fine particles and leaching of water-soluble alkaline components to the surface side, and the hardening of the colored decorative coating material is further prevented during the period when the oil film gradually evaporates. At the same time, fine particles and water-soluble alkaline components are fixed inside the colored decorative coating material, and their leaching to the surface can be prevented.

Furthermore, even if a certain amount of material leaches onto the surface, the oil film on the surface covers and traps the colored pigments, fine particles, and water-soluble alkaline components contained in the colored cosmetic coating material on the inside of the surface, preventing their dispersion and enveloping them even more thoroughly. It can prevent the occurrence of rash and efflorescence.

By repeating the application of the same anti-embedding and efflorescence paint after applying the pattern, it is possible to correct some of the unevenness caused by the coating and to add the waterproof and water repellent properties of the sprayed paint. is also carried out.

As a result of experiments, it was found that in carrying out the present invention, it is necessary to mix either silicone resin oil liquid or liquid paraffin with the above-mentioned mineral oils. It is also possible to use a mixture of both silicone resin oil and liquid paraffin.

As the colored decorative coating material used in the present invention, in addition to the above-mentioned inorganic coating materials such as cement, mortar, dolomite silastar, lime, and gypsum, organic coating materials such as acrylic resin, vinyl acetate resin, and urethane resin may be used. I can do it.

Pigments that should be added to these inorganic and organic coating materials for coloring include commonly known inorganic pigments such as Bengara (red), chrome green (blue-green), and iron oxide (yellow). In addition, ordinary organic pigments and dyes can also be used.

Handling tools used for attaching handles include trowels with patterns engraved on them made of metal or glass, as well as rollers with engraved designs made of natural rubber, synthetic rubber, urethane rubber, plastic, etc. A cylindrical roller is suitable.8 The present invention particularly increases the utility value of colored inorganic and organic coating materials as decorative coating materials, and is especially suitable for applying a topcoat of a colored coating material for cosmetic use to a base coated surface containing a water-soluble alkaline component. When applying this method, it is possible to prevent the occurrence of embedding and efflorescence, and to easily form painted surfaces such as walls, floors, and ceilings that contribute to improved fire protection performance.

Furthermore, since the paint of the present invention is highly waterproof and water-repellent, it can also prevent secondary efflorescence on the surface coated with cosmetic paints, and therefore can particularly effectively remove and improve the defects of inorganic decorative paints. In addition, examples are described below, in which it is possible to save on the process and contribute to shortening the construction period and saving labor without performing separate waterproofing or water-repellent construction.

Example 1 (Paint) Approximately 1.5% of a silicone resin oil was added to kerosene having a boiling point of Jio'C or higher, and the mixture was uniformly blended to obtain an anti-Japanese paint.

Example 2 (Paint) Liquid paraffin was added to light oil with a boiling point of 60'C or higher at a concentration of about 1.0%.
and uniformly blended to obtain an anti-embedding and efflorescence paint.

Example 3 (Paint) Silicone resin oil liquid 0.5 in kerosene with boiling point (50°C or higher)
0.5% of alcohol and liquid paraffin were added and blended uniformly to obtain an anti-embedding and efflorescence paint.

Example 4 (Construction method) Apply a pigment such as Bengara 1 or Malachite IX to ordinary Shichiment mortar or Tahadlomite Zolastar with the required amount of water on the surface of the wall coated with ordinary cement mortar. Immediately after coating and kneading the colored decorative coating material, apply one of the anti-embedding and efflorescence coating materials obtained according to Examples 1, 2, and 3 above using a spraying device. 50C for 3.3m of colored cosmetic coating surface! ,
C! Immediately after spraying, the desired pattern is applied using a cylindrical rubber roller with a pattern engraved on the circumference, and immediately after that, the same wrapping and efflorescence are applied again. The protective coating was sprayed repeatedly at a concentration of about 15 to 200.0, and then left to dry naturally.

Example 5 (#! Method) Instead of the inorganic colored cosmetic coating material in Example 4, an organic colored cosmetic coating agent made of polyvinyl acetate resin and a known plasticizer and a pigment such as phthalocyanine blue was used to apply a top coat. Thereafter, the coated wall surface was wrapped in the same manner as in Example 4, and the anti-efflorescence paint was sprayed to complete the construction.
