Abstract

PROBLEM TO BE SOLVED: To obtain a decoration face with a light and shake pattern without generating dust, by forming an uneven substrate layer made of an substrate material with inorganic aggregate on a base body and making smooth the surface and applying a plurality of layers of semi-fluid paint by a trowel. SOLUTION: Inorganic aggregate such as calcium carbonate or the like is mixed with a binder such as synthetic resin emulsion or the like and then, a thickener, a deforming agent, or the like is added thereto to prepare a substrate material with a required viscosity. At first, the substrate material is applied on the base member 1 to form a substrate layer 2 having an uneven surface. Then, a semi-fluid resin emulsion paint is applied by a trowel while rubbing the paint so as to make roughly smooth the uneven face of the substrate layer 2 and form the first layer 3 applied by a trowel. Then, the second and third layers 4, 5 applied by a trowel are formed likewise on the first layer 3 one by one. In this way, a flat decoration face with a light and shade or a thick and thin pattern can be easily obtained by forming respective first-third layers. And occurrence of dust or the like can be prevented during the work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for forming a decorative surface according to the present invention will be described below in detail with reference to the drawings.

FIGS. 1 to 4 are sectional views showing steps of a method for forming a decorative surface according to the present invention, and FIG. 8 is a flowchart showing steps of a method for forming a decorative surface according to the present invention. That is, FIG. 1 shows a state in which the base layer 2 is formed by applying an aggregate-containing base material onto the base 1 so as to have irregularities. As the above-mentioned base material containing an aggregate, a binder containing a mortar such as cement or resin mortar mixed with an inorganic aggregate or the like, or a synthetic resin emulsion is preferable.

As the above-mentioned aggregate, inorganic aggregates such as calcium carbonate, talc, cold water, silica sand, and shirasu are preferable. In particular, since shirasu is soft, when added as an aggregate, the shirasu has an advantage that the workability is very good and the decorative surface is not damaged. The size of the aggregate is not particularly limited, but the size (major axis) is about 5 m.
m or less, particularly preferably 3 mm or less.

Various binders can be used as the mortar such as cement or resin mortar mixed with the above-mentioned aggregates, and synthetic resin emulsions. Emulsions are preferred. Examples of the synthetic resin emulsion include emulsions of vinyl acetate resin, vinyl chloride resin, acrylic resin and the like. In particular, for exterior use, an acrylic-silicone resin emulsion, a fluororesin emulsion, or the like having excellent weatherability can be suitably used. In the present invention, the above-mentioned synthetic resin emulsion is not particularly limited, but it is desirable that the synthetic resin emulsion has a concealing property of the substrate 1 and is of a degree which is hardly transparent.

The binder such as a synthetic resin emulsion mixed with these aggregates can be adjusted for spraying, brush coating, roller coating, and the like, and is preferably adjusted to a desired viscosity for spraying. . For example, 5 to 25 parts by weight of a synthetic resin emulsion having a solid content of about 40 to 60% by weight based on a total of 100 parts by weight of the above-mentioned aggregate, and if necessary, a thickener, an antifoaming agent and the like are added to adjust the pH to 8 to It can be obtained by mixing at around 10 and adjusting to high viscosity. Although the viscosity is not particularly limited, it is preferable that the viscosity is set to such a degree that the uneven pattern does not easily disappear when a layer is formed on the surface of the base by spraying or other methods. For example, 10,000 to 50,000 cps
The degree is used.

Next, as shown in FIGS. 2 to 4, the surface of the underlayer 2 having the uneven pattern is sequentially patterned. That is, ironing is applied to the underlayer 2 while squeezing a semi-fluid paint so that the uneven surface is substantially smooth, thereby forming the first ironing layer 3 as shown in FIG. As the semi-fluid paint used at this time, the material used for forming the underlayer 2 can be used. At that time, the extender pigment which may be added is preferably as small as possible in particle size, for example, several tens μm or less.

The viscosity of the semi-fluid paint is selected so that the ironing work can be easily performed while ironing the base layer 2 while ironing. For example, a paint whose viscosity is reduced to about 30,000 to 100,000 cps by adding 1 to several percent of water can be used.

When ironing the above semi-fluid paint while ironing it, the paint having a little fluidity is coated with an iron or a spatula.
This is to rub the base layer 2 with force into the base layer 2. The pattern of the pattern (eg, how the eyes flow, smoothness, etc.) is determined mainly by the method of ironing the first layer.

Next, similarly, as shown in FIG. 3, a second ironing layer 4 is formed on the first ironing layer 3 by ironing using a semi-fluid paint and ironing. FIG. 4
The third ironing layer 5 is formed on the second ironing layer 4 as described above.

By forming each layer between the first ironing layer 3 and the third ironing layer 5, the decorative surface obtained is very flat and a decorative surface having a light and shade pattern can be obtained. Possible reasons for this include a difference in the thickness of the coating film due to the uneven pattern of the underlayer 2 and a difference in the paint concentration due to the absorption of moisture or the like into the underlayer 2. Further, the projections and the like of the uneven pattern of the underlayer 2 that are strongly squeezed during the ironing exhibit a very dark color due to a change in density or the like, and appear as a shaded pattern, as shown in FIG. , Or a light and shade pattern 6.

In the above embodiment, the state in which the iron coating layer is formed in three layers is shown. However, if it is one layer or more, it may be two layers or four or more layers.

The decorative surface thus obtained comprises: a. The surface is flat and resistant to contamination b. Develop new shades or shades c. Presents a very deep pattern d. The direction and length of the shading or shading pattern changed depending on how the iron or spatula was rubbed, and had the excellent advantage that a desired pattern could be obtained.

The obtained decorative surface can be seen from the results of various tests.
It has been found that it is possible to provide a cosmetic surface exhibiting extremely excellent weather resistance and having little discoloration over a long period of time.

The obtained decorative surface can be applied to the inner wall, outer wall, ceiling, etc. of a building as it is or after polishing the surface and coating the surface with various clear materials.

FIGS. 6 and 7 show steps of forming a decorative surface in a tile shape by using the method of forming a decorative surface according to the present invention. That is, as shown in FIG.
Are attached vertically and horizontally on the substrate 1 at predetermined intervals. Then, from above, an aggregate-containing base material is applied onto the base 1 so as to have irregularities, the base layer 2 is formed, and the joint tape 7 is peeled off.

Thereafter, the first iron coating layer 3, the second iron coating layer 4, and the third iron coating layer 5 are sequentially ironed onto the base layer 2 while being ironed, and a clear coat is applied as required. Finally, as shown in FIG. 8, the groove 8 formed by peeling the joint tape 7 is filled with the joint material 9 to complete the construction.
