Description

  TECHNICAL FIELD The present invention relates to a top coating material and a design property imparting method for creating a sense of design by applying on a wall on which irregularities are formed with a coating material.

  There is wiping as a technique for coloring the wood grain conduit portion and improving the wood grain design. Many of these are applied to embossed decorative boards and are used as decorative materials with high design. Since these are plate materials, they can be processed horizontally, and application and wiping can be performed by a machine, but the embossed shape is limited to a sharp one. On the other hand, the wiping method is tried for the purpose of thickening the coating material on the wall material, embossing it with a letterpress roller, coloring the concave portion after drying, and obtaining an old and calm design and a three-dimensional impression of unevenness. However, the unevenness of the coating material, the cloth cloth to be wiped off with the hardness will be worn away immediately, or the time of wiping after application can not be constant, resulting in an unnatural shade, It could not be adapted to large area walls.

In addition, an old color finish called “aging” is adopted by shop assistants, but it was based on the craftsman's drawing skills and was not a common painting method.
JP 2000-327949 A

  The problem to be solved is to give a sense of design to the wall surface, that is, the vertical surface, and with a simple coating method, a large area can be easily formed in a short time without any unnaturalness, and the uneven shape and depth of the wall. The present invention provides a method for increasing the design value of a wall that is colored in a concave portion and is “old, calm, deep, imparting a color contrast, etc.” and a top coating material thereof.

The invention of claim 1 is a design imparting method having at least a step of applying a design paint to a wall surface provided with irregularities and a step of scraping off with a rubber scissors, and by scraping off with a rubber scissors, A large area can be finished uniformly.
In the invention of claim 2, the concealment ratio of the 0.125 mm film thickness of the coating material for design is 0.3 to 0.4, the coating material viscosity is 2 to 25 Pa · s, and the TI value is 2.2 to 2.7. With this design coating, it is possible to finish without defects with this concealability, viscosity, and viscosity structure index. By using the design paint, it is possible to impart design characteristics according to the unevenness of the wall surface, even if the skill of the operator is immature, no unnatural lines are produced, there is no shading in the liquid, and the color of the groundwork Harmony with is natural.

  The effect of the present invention is that it is possible to impart a design change to the concave portion or step portion of the wall surface that is vertical, the resistance of the rubber hook is low, the concave portion is followed, the concave portion is not left unpainted, and the paint is processed after the treatment. It is a paint and method in which there is no dripping, unnatural lines due to the amount of paint, and accumulation is not noticeable.

The present invention will be described in detail below.
The wall surface with the unevenness is a wall surface newly provided or with existing unevenness. The exterior thin coating material E, the flexible exterior thin coating material E, the interior thin coating material E, the exterior thick coating material E, and the interior thick coating material E specified in JIS A6909. It is the wall surface which gave the unevenness | corrugation with the relief roller related to an unevenness | corrugation after application | coating coating iron finish surface application | coating, etc. or before drying after application | coating coating, and dried.
For the corresponding irregularities, the specifications of “Escent Brick”, “Ancient Brick S”, “Written Skin”, “Diatomaceous Earth Flat”, “Quarter Moon”, “Ancient Brick KS”, “Art” Like “Cliff” and “Scraping off”, a design with a flat feeling that remains after rolling the added aggregate (cold stone), “turbulent flow”, “turbulent flow R”, “mild plaster”, “ Designs with a flat feeling remain after the iron moves without adding aggregate, such as “Mild Plaster Random”. However, these are only examples, and can be applied to walls with irregularities and steps.
The top coating for design is composed of additives such as pigments, thickeners, surface appearance, wettability, surfactants for the purpose of eliminating pinholes, etc. in synthetic resin emulsions, adhesion to the wall surface, light resistance, The formulation is determined by weather resistance, stain resistance, dust resistance, etc. Necessary viscosity is suitability for spraying, rolls, etc. When shear is applied, viscosity, that is, shear stress is reduced, light work, smooth sprayability can be obtained, and viscosity is quickly applied after application. Ascending and less dripping. Further, in the present invention, since it is scraped off with a rubber scissors, it is necessary that the viscosity is lowered again and the ironing is easy. In the present invention, it is desirable that the viscosity at 20 rpm is 2 to 25 Pa · s and the TI value related to thixotropy is 2.2 to 2.7. When the viscosity is less than 2 Pa · s and the TI value is less than 2.2, the design paint applied to the recesses and steps is dropped after being scraped off with a rubber scissors, and a clear design property cannot be obtained. If it exceeds s and the TI value exceeds 2.7, the resistance at the time of application will be large, the coating material for design will not enter the recesses, and the adhesion will be insufficient.
In addition, coloring is determined according to the color tone of the wall, but if the concealing property is too high, the lines on the rubber ridges become clear, and the paint pool is conspicuous. On the other hand, if the concealing property is low, the desired design can be obtained. In order to obtain it, a large coating thickness is required, and as described above, a paint reservoir is conspicuous after the rubber bowl. The concealment rate of 0.125 mm is preferably 0.3 to 0.4. About solid content, 5 to 40 weight% is preferable. When the solid content is less than 5% by weight, the coloration of the recesses is insufficient, and the effect of applying the paint cannot be obtained. If the solid content exceeds 40% by weight, the material remains other than the recesses, and the intended design cannot be obtained. In addition, the material accumulates in the concave portion, and the design and the unevenness before the material is applied are remarkably changed. The solid content of the paint is most preferably 10 to 20% by weight.

It is desirable to use a rubber jar for scraping the paint. This is because the paint can be scraped off corresponding to small irregularities on the surface, and a design that does not cause a difference in skill among workers can be obtained. The rubber scissors can be scraped uniformly due to the rigidity and elasticity of the support and the rubber part, and the change in design can be enriched by changing the flexibility of the rubber scissors as a scissors. The tool for scraping the paint is not limited to the rubber bowl, and rubber products such as rubber spatula are suitable. Synthetic rubber such as natural rubber, styrene butadiene rubber, butyl rubber, acrylic rubber, urethane rubber, silicone rubber, etc. is suitable for the rubber material used, and its hardness is 20-100 IRHD (JIS K6253 vulcanized rubber and thermoplastics) It is desirable that the rubber hardness test method). The shape is preferably a plastering saddle or spatula. In detail, in the case of a bag, it is affixed or molded to the support so that the end of the rubber or elastic body is almost parallel to the long side of the substantially pentagonal support of the plasterer. It is preferable that the end of the elastic body protrudes. Similarly, for the spatula, it is preferable that the end of the rubber or elastic body protrudes from the support at the linear portion of the support. The length protruding from the support is more preferably not less than the thickness of the rubber or elastic body and not more than 5 times. By protruding, it can be scraped off along the flat part of the wall surface. If it is less than the thickness, the angle with the heel wall is not wide, and if it exceeds 5 times, workability is impaired and many artificial defects are generated. The elastic body includes a foam and a sponge body.
When a metal plastering iron is used, it is impossible to scrape the paint on the construction surface, and the design is based on personal skills, and the design according to the present invention cannot be obtained.
As the synthetic resin emulsion, an acrylic resin emulsion, a urethane resin emulsion, an acrylic silicone resin emulsion, a silicone resin emulsion and the like can be used, and an acrylic resin emulsion having high weather resistance is most preferable.
