Description

[Detailed Description of the Invention] [Industrial Field of Application] Materials with relief patterns are widely used in various fields including exterior and interior applications of architecture [Conventional Technique #i1] Typical methods for forming relief patterns on the surface of the mortar layer include (1) method using a trowel and spatula;
) Roller (・(− method, (3) Spraying method (
4) Embossing method, (5) Blasting method, etc. are known.

However, method (1) was developed as a finishing method for plaster walls, and it was extremely difficult to form a matching relief pattern and required skill. J In addition, method (2) is suitable for forming simple repeating patterns because it forms unevenness by stamping with a P-turn roller, but it is suitable for forming complex and fine patterns. In addition, method (3) is suitable for forming random uneven patterns using a spray gun, but it is not suitable for forming arbitrary patterns such as a single character. It had the disadvantage that it was difficult to form.

In addition, (4), V-, is a method suitable for producing dogs and cattle in factories, and A is a method that is suitable for producing dogs and cattle in factories. So it's 7b.

Method (5) is to partially remove the mortar layer from

Furthermore, the following method is known as a means of making the concrete surface uneven in order to improve the adhesion between the mortar and concrete when mortar is applied to the concrete. In other words, a concave-convex shaped Coni-Crete 9-or is manufactured by partially applying a cement hardening agent to the frame, then pouring concrete into the form, curing it, and then washing it out. This is the way to do it.

In view of the current situation in the field of embossed patterns as described above, T et al. conducted a thorough study on a method for easily forming a clear, non-random embossed pattern on any base material without requiring any skill. As a result, we have arrived at the present invention.

[Means for solving problems]

That is, the present invention has the following steps: (1) Apply rutal to the base material, and apply the coating to the base material.
(11) While the mortar layer is uncured, a notebook with a pattern formed from the feed material 6 part and the liquid part 1 is placed on the mortar layer p (-). After or after placing the WE body-impermeable sheet in a oval shape on the gold mortar layer, applying a cement hardening retardant solution to the surface of the mortar layer, (ii+) After removing the sheet, curing the mortar layer. (1v) After curing the mortar layer, cleaning and removing the mortar layer at the locations where the cement hardening retardant solution has been applied. be.

In the method of the present invention, the mortar layer is impregnated with a cement hardening retardant solution according to the pattern of the sheet that is in close contact with the uncured mortar layer. Therefore, the areas impregnated with the curing retarder are delayed in curing and can be easily removed by washing even after curing. It has the feature that a relief pattern with deep unevenness can be formed on the surface of the mortar layer.

In addition, in the present invention, the thickness of the mortar layer and l=/
By appropriately controlling the degree of impregnation and removal of Nol-hardening slow wax cutting, it is possible to improve the Q
), it has the advantage of being able to freely form relief patterns with unevenness of a desired depth, even those with deep unevenness. Furthermore, the method of the present invention has the advantage that since the relief pattern is made of a mortar layer, it is possible to form a relief pattern with deep unevenness at a very low cost.

Hereinafter, the method for forming a relief pattern having unevenness according to the present invention will be explained in more detail.

First of all, the base materials used in this issue are known)
It can be applied to any base material that can adhere to Rutaru. For example, metals such as iron, aluminum, stealth, glass, tiles, ceramics, and concrete.

Examples include brick, stone, wood, glass, and laminates thereof. The forest surface does not necessarily have to be a flat surface, and may be a curved surface, for example. These base materials can be made into a river surface, colored, or lubricated as needed.
It is also possible to apply a primer or other surface treatment.

In the present invention, as the first step, a mortar layer is formed by applying the mortar layer onto the base material by a commonly used means such as a trowel, a spatula, or a spray. The thickness of the mortar layer is not particularly limited. However, depending on the depth of the carving of the unevenness, it is preferable for practical use to be about 1/-=20 mm.

As the mortar used in the present invention, any mortar that has been commonly used can be used as is. In other words, seven meters/to,
It consists of aggregates such as sand and water, and if necessary, coloring pigments, various additives, etc. are added. In addition, so-called resin mortars containing acrylic resin thread emulsions, vinyl acetate resin emulsions, niboxy resin emulsions, styrene-butadiene resin thread emulsions, etc. can also be used in the present invention.

In the present invention, for the mortar layer, in addition to using mortar of the same color, mortar of different colors can be applied multiple times. By forming a plurality of mo/L layers having different colors in this way, it will be described later. -In the rp removal process, by adjusting the degree of removal at each location when cleaning and removing the mortar layer, that is, the depth of the four parts, a relief pattern with multicolored variations can be created depending on the depth. It becomes possible to form.

While the mortar layer formed in this manner is not yet cured, preferably when the free water on the surface of the mortar layer disappears and the mortar layer does not deform when lightly pressed with a finger, the liquid permeable portion and the liquid permeable portion are separated. The sheet with the pattern formed thereon is brought into close contact with the surface of the mortar layer.

Specifically, the /-t is preferably a silk screen commonly used in the paint industry.

Alternatively, a sheet cut out in a pattern (so as to form a desired pattern) may be brought into close contact with the surface of the mortar layer.

In another variation of the present invention, the liquid-impermeable notebook may be applied to the mortar layer so that the seal forms a pattern.

VCL 'C'/-t like this:
, (/LI C') After 14 minutes, apply 1! to the surface of the mortar layer from above the sheet. Apply curing retarder solution.

Furthermore, the applied cement retardant solution is impregnated into the mortar layer other than the one in close contact with the liquid-impermeable part of the notebook.

That is, in order to place the sheet on the mortar layer while the mortar layer is uncured, there is no space between the sheet and the mortar VIP sheet (liquid impermeable portion), and the sheet is placed on the mortar layer while the mortar layer is uncured. The covered mortar layer is not impregnated with the cement retarder solution.

However, by adjusting the viscosity of the cement hardening retarder solution and the application lid, the depth of the unevenness can be changed freely.

That is, for example, by reducing the viscosity of a cement hardening retarder,
And/or by increasing the amount of application, the cement hardening retarder can be impregnated more deeply, so the depth of the unevenness can be increased.

The viscosity of the cement hardening retardant solution used in the present invention is 4'', and considering the permeability into the mortar layer, it is 10-10.

In the present invention, as the cement hardening retardant solution, those commonly used in the past can be used as is! 74
1 u [capable. Specifically, representative examples include ptrium dihydrogen phosphate, disodium hydrogen phosphate, sodium phosphate, sodium tetraborate, sugars, calcium acetate, oxycaldate, lignin sulfonate/alcohol, etc. It can be given as In addition, solid substances are used as aqueous solutions. If the viscosity is lower than the above range, the viscosity can be adjusted to the above range by adding a thickener such as polyvinyl alcohol, methylcellulose, sodium alginate, bentonite, or the like.

In addition, by applying a cement hardening retardant solution containing a coloring agent to the mortar layer, the areas that are impregnated with the hardening retarder solution and should be cleaned and removed can be identified by coloring, which will be explained later in the cleaning process. It may be useful in the removal process.

In the present invention, after applying the cement hardening retarder solution,
The sheet is removed, and then the mortar layer is allowed to cure for a certain period of time. As the curing method, a natural curing method, a steam curing method, a pressure curing method, etc., which are generally known as mortar curing methods, can be adopted.

The curing time is determined by the cleaning and removal process described below.
The mortar layer in areas where the cement setting retarder solution has not been applied or impregnated is hardened to the extent that it cannot be removed, and the mortar layer in areas where the cement setting retarder solution has been applied or impregnated is uncured or relatively easily cured. This is the time allowed to semi-cure to the extent that it can be removed. Specifically, for example, in the case of a natural curing method, it is preferable to set the temperature at room temperature (20°C) for ~j'θ hours.

After curing the mortar layer, use a cleaning solution consisting of water or water and a solvent, and scrub it with a rotating brush.
:) Or by means such as high-pressure spraying of the cleaning liquid,
The mortar layers impregnated with a cement hardening retardant solution are washed and removed.

In this way, it is impossible to obtain a mortar layer that forms a relief pattern with deep unevenness. In the present invention, it is also possible to add color and adjust the degree of gloss depending on the membership fee.

Furthermore, in order to provide weather resistance, water resistance, chemical resistance, etc.
The entire surface can also be coated with another colored coating on the concave portions (or convex portions), or the entire surface can be coated with a clear coating, or a coat of color clear or the like can be applied, or it can be polished.

As described above, by the method of the present invention, it is possible to easily and inexpensively obtain a relief pattern having deep unevenness of any depth. Also see) KJiJ Narasil
, by changing the fC pattern in various ways, it has the advantage that a desired uneven pattern can be easily obtained.

Furthermore, the mortar layer with an uneven pattern obtained by the method of the present invention can be used as building materials, decorative items, etc., and has the feature that it can be manufactured in a factory or on-site.
