Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a pattern on a floor surface, etc., and particularly relates to a method for forming a pattern on a floor surface, etc., and in particular, a method for forming a pattern on a floor surface or the like, and in particular, a method for forming a pattern on a floor surface, etc., which is easy to construct on-site, and is suitable for forming a large number of densely packed, small-shaped, unique patterns on a substrate such as a floor surface. This invention relates to a method for forming patterns on surfaces, etc.

To form a dense pattern of unique small shapes on the floor etc.,
For example, colored tiles, etc. are pasted in advance to a mount of a certain size in a patterned state, and then placed and fixed one after another before the top layer of the floor surface etc. hardens, and the joints between the tiles are Fill it with joint material (this is done,
Pattern formation using this method has a limit to the size of the pattern, and it is not possible to form a large number of fine, densely packed patterns of different colors. In addition to being extremely troublesome during construction, it also had the drawback that the pattern was difficult to form, especially in the side lines and some corners of the construction area, which had an unfavorable effect on the finished state. . There are also unit floor boards that have a finished surface with a pre-formed pattern of small, dense shapes, but in this case as well, the pieces are pre-produced in a factory to a certain size and then adjusted to the shape of the processed parts on site. At the same time, installation, cutting, etc. must be carried out, which is extremely disadvantageous in terms of construction, as well as being inconvenient in terms of handling and transportation.

In view of the above-mentioned drawbacks, the present invention provides a method for forming patterns on floors, etc., which can be directly applied on-site, provides a good finish, and can extremely easily form small, dense patterns. The gist of this is that a base paste is spread evenly and hardened so that small lumps of synthetic resin foam are mixed on a base layer such as a floor surface, and then the foam is cured. A method for forming a pattern on a floor surface, etc., by dissolving it with a solvent and further applying a filling paste of a different color from the base paste so as to fill the foam-dissolved recesses of the base paste, thereby forming a different color pattern on the floor surface, etc. It is in.

Hereinafter, the present invention will be further described in detail based on the illustrated embodiments. FIGS. 1 to 5 are enlarged cross-sectional views of essential parts showing each construction process in an example of implementing the method of the present invention. FIG. 2 is a partial perspective view of a floor surface etc. formed by the method of the present invention at ζ.

According to the method of the present invention, first, as shown in FIG.
A base paste 3 in which a large number of small styrene foam spheres 2 as a foamed polystyrene foam is mixed in advance is applied to a base 1 consisting of a decorative mortar layer, etc. ) Apply evenly to form the following thick layer. The size of the spheres 2 does not necessarily have to be constant, and spheres of arbitrary diameters may be mixed. The base paste 3 may be a solvent-free type based on each resin such as epoxy, urethane, or acrylic, or an emulsion type of these resins, or a latex-based base paste, and may also contain pigments, fillers, etc. Consists of the addition of. The composition of the base paste 3 as an example is as follows, for example.

Example 1 Base Epoxy resin 60% Pigment (
Toner) 10% Curing agent Modified aliphatic polyamine The above base and curing agent are blended in a weight ratio of 10:20 to form a solvent-free epoxy resin paste.

Incidentally, 2 to 3 foamed polystyrene spheres are mixed into the paste in a weight ratio to obtain a base paste in which the foamed polystyrene spheres have been mixed in advance.

Example 2 Base Urethane prepolymer curing agent Modified aromatic amine 40% plasticizer (DOP
),, 15% Filler (calcium carbonate) 38% Pigment 7q6 The above base and curing agent are blended in a 1:1 weight ratio to form a solvent-free urethane resin paste. In addition, 2 to 3% by weight of expanded polystyrene spheres are mixed into the paste,
A base paste is prepared in which styrofoam spheres are mixed in advance.

When applying the paste 3 to the base 1, if the base paste 3 is a solvent-free type, in order to improve the adhesion between the two, use the same base resin as the base paste 30. It is preferable to apply a solvent-based primer 4 made of a resin or the like.

The composition of the solvent-based primer 4 as an example is as follows, for example.

Example 3 Base modified epoxy resin 47% solution
Curing agent 53% Curing agent Modified alicyclic polyamine 63% solvent
32% The above base and curing agent are mixed in a weight ratio of 1:1 to prepare a solvent-based epoxy resin primer.

Example 4 Urethane prepolymer: 42 cm Solvent: 58 cm When the base paste 3 coated in this manner is cured, it is preferable that the foamed polystyrene spheres 2 mixed in the base paste 3
0. Polish a part of the base paste 3 using a known polishing machine so that most of it is about the same size as the diameter.
Figure 2). This polishing is not necessarily necessary if the base paste 3 is applied in such a way that the foamed polystyrene spheres 2 protrude from the base paste 30 surface by about half of their diameter, but by polishing, the entire surface 3a Since the surface is formed into a planar shape, post-processing is easy and the finished surface is in a good condition.

Next, by applying a solvent such as trichlorethylene, methyl ethyl ketone, or thinner to the entire surface of the base paste 30 polished in this way, the foamed polystyrene spheres 20 embedded in the base paste 3 are removed.
Let the parts dissolve.

As a result, the part where the sphere 2 was present is opened, and a small amount of the molten resin component 5 remains at the bottom, but the base paste 3
A large number of partially spherical recesses 3b are formed on the layer (FIG. 3). In this case, as described above (base paste 3
If the foamed polystyrene sphere 2 is cured so that it protrudes by about half its diameter from the 0 side, a solvent is applied as it is to dissolve the sphere 2, but in this case, the base paste 3 The surface 3a has an uneven shape with the periphery of the recess 3b being slightly raised. Note that when dissolving the expanded polystyrene spheres 2, the solvent-based primer 4
It may be dissolved using.

In this way, filler paste 6 is applied to the large number of recesses 3b that are formed in a state where they are appropriately close to each other and separated from each other as appropriate. It is poured and hardened to such an extent that the recess 3b is filled (FIG. 4). Thereafter, polishing is performed using the same polishing machine as described above until the contour shape of the recessed portion 3b becomes clear, thereby forming a finished surface 3C (FIG. 5).

As a result, as shown in FIG. 6, the surface of the floor surface 70, etc., has a large number of small circular filling pastes 6 disposed on the surface of the base paste 3, so that the surface of the floor surface 70, as shown in FIG. It is possible to create a pattern in which many circles are arranged. In the above process, if polishing is not performed after applying the base paste 3, the concave portion 3 of the styrofoam sphere 2 will be removed after melting.
The filling paste 6 will be applied while the peripheral edge b is raised against the surface 3a, but if the polishing is finally performed up to the surface 3a, the finished surface will be the same as the above polishing. It is possible to form a pattern surface exactly the same as that in the case where the

By the way, in the above pattern formation, if the base paste 3 and the filling paste 6 are pastes using different base materials (for example, epoxy resin and acrylic resin), the same base material as the base of the filling paste 6 may be used. Preferably, the primer is applied after the foamed polystyrene spheres 2 are melted, and then the filling paste 6 is filled and applied. By doing this, the adhesion between different pastes is improved, and even if the depth of the recess 3b of the base paste 3 is shallow, the filled portion of the filling paste 6 will not peel off later.

In addition, in the above embodiment, the case where the coloring agent of the filling paste 60 is a pigment was explained, but the filling paste is constituted by using a dye as the coloring agent and a transparent resin as the base resin. When filling the paste 6, use this transparent filling paste to fill the recesses 3b of the base paste 3.
In addition, if the transparent filling paste is applied to such an extent that the entire area is thinly covered, the color of the base paste 3 can be almost completely changed through the thinly applied transparent filling paste layer without any polishing operation. It can be seen through, and since the fourth part 3b is a thick layer, the color of the transparent filling paste appears dark. It becomes possible to visually recognize the pattern as a pattern.At this time, if the Styrofoam sphere 2 is melted and filled with transparent filling paste without polishing after applying the base paste 3, the periphery of the recess 3b will be raised. It will remain in the raised state, but in this case, the transparent filling paste may be applied to cover the raised portion so that the final finished surface will be flat.

Incidentally, even when a pigment is used as a coloring agent for the filling paste 60, if the filling paste 6 is polymerized and applied in an extremely thin state to the surface portion 3a of the base paste 30, it can be left in that state without polishing. However, it is possible to make the color of the base paste 3 appear through the thin layer of the filling paste 6.

Furthermore, in the above-mentioned embodiment, the case was explained in which the foamed polystyrene spheres 2 were mixed into the base paste 3 in advance, but the foamed polystyrene spheres 2 were kept separate from the base paste 3, and during construction, First, only the base paste 3 may be applied, and immediately after that, the foamed polystyrene spheres 2 are scattered on the coated layer at predetermined intervals, and the foamed polystyrene spheres 2 are caused to sink into the base paste 3 by their own weight. . This method is
This is particularly effective when the expanded polystyrene sphere 2 is relatively large. In this case, the spread polystyrene foam spheres 2 may be pressed from above with a flat plate or the like to force them to sink.

In addition, when filling and applying the filling paste 6 to the layer of the base paste 3, the negative color filling paste 6 is applied to the entire surface to scatter a large number of small circles on the base to form a two-color pattern. In addition, by dividing the surface as appropriate and using a different colored paste for each division, in addition to the basic small circular pattern, different colored patterns can also be formed on parts with a certain extent. is possible.

Note that the present invention is not limited to the contents of the above-mentioned embodiments, and for example, the material and shape of the foam can be arbitrarily selected, such as a cube, a cone, an oval shape, a star shape, etc. The applicable surface may be a wall surface in addition to the floor surface.

As described above, according to the method of the present invention, it is possible to easily form a pattern on a floor surface, etc., on-site construction, and also to form a pattern on a floor surface etc., even to the edges, corners, etc., of any part to be constructed.
It is possible to create patterns extremely easily and uniformly,
It is particularly effective in forming patterns with densely packed small shapes.
