Abstract

PROBLEM TO BE SOLVED: To easily remove a mold member in the formation of an irregular pattern on a surface to be constructed by molding a body of polyolefin plastic, sticking the mold member having silicone oil mixed thereto to a recessed part forming position at the time of molding, and removing the mold member after an applied application material is substantially hardened. SOLUTION: A silicone oil-containing foamed polyethylene sheet 2 having an adhesive applied to the lower surface and a covering thin plastic film 5 having an adhesive applied to the lower surface are successively stuck onto a release paper 3 to form a joint pattern forming mold member 1 by use of a punching machine. The release paper 3 is removed, a wall surface bed 7 is placed on a smoothly bed-regulated surface to be constructed, and a spray material 8 mainly composed of an acrylic resin emulsion is uniformly sprayed to the wall surface, and the surface film 5 is removed while an application material 8 is not dried. After the application material 8 is sufficiently dried and solidified, the mold member 1 is peeled and removed from the wall surface, whereby an irregularities pattern can be formed on the surface to be constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the surface of various panels and boards used for the interior and exterior surfaces of buildings, such as walls, pillars, ceilings, floors, etc. Further, the present invention relates to a concave and convex pattern forming mold member and a concave and convex pattern forming method for forming concave and convex patterns, such as various joint patterns and line patterns, which appear deeply and clearly with ridge lines, very easily and reliably.

[0002]

2. Description of the Related Art Recently, a method of using a spraying material to perform a high-quality finish resembling a brick or tile attachment has been adopted. This is a plastic film or cardboard pattern that has been punched out of a joint pattern, attached to a wall or the like, and sprayed from above, and then the pattern is peeled off to reveal the joint pattern. The construction efficiency is greatly improved as compared with the case where one sheet is attached.

[0003]

However, if the spray material is dried and solidified, it becomes difficult or impossible to peel off the pattern paper. Therefore, it is necessary to peel the pattern paper from the work surface immediately after spraying or when the spray material is semi-dried. . It therefore inevitably sag occurs, can not be the ground thickness is sagging when the blow thickness Coatings large, there is give only drawback low uneven contrast ones.

[0004] Therefore, it has been considered that the pattern paper is made of plastic and a release agent is applied to the surface thereof so that thinning can be performed even after the spray material has hardened to the extent that it does not drip.
In the portion where the release agent was sufficiently applied, it could be removed relatively easily even after curing.

However, it is troublesome to apply a release agent to the surface of the mold member, and it is difficult to apply the agent uniformly. When the spraying material is applied thickly, the thickness of the mold member must be increased. In this case, since the release agent must be applied to the wall surface of the mold member, the release agent cannot be applied unless the mold member is cut into a shape to be used. Then, the application of the release agent is a very laborious operation.

[0006]

In view of the above situation, the present inventor has completed the mold member and the forming method of the present invention as a result of intensive studies. If there is a place where the concave part of the work surface should be formed,
A mold member used for a method of attaching a mold member, applying an application material, and removing the mold member after the application material is substantially cured, wherein the main body is made of a polyolefin-based plastic and molded. The point is that silicone oil is sometimes mixed in, and in the forming method, a mold member is attached to a portion where a concave portion is to be formed on the work surface, and a coating material is applied, and after the coating material is substantially cured. The method for removing the mold member is characterized in that the mold member is made of a polyolefin-based plastic and that silicone oil is mixed during molding.

[0007] The coating material is a material applied to the surface to be processed, and may be a so-called spraying material, a pavement material, or the like. Usually, it is a mixture of a resin or an inorganic material (such as cement) and an aggregate, and other various additives may be mixed. The resin may be of any type such as an emulsion type or a solvent type. Acrylic resin, epoxy resin, urethane resin or the like is used as the resin. Resin or cement without aggregate may be used alone.
That is, the present invention itself is irrelevant to what the coating material is.

[0008] The coating may be performed by any method such as trowel coating, spraying, roller coating, and brush coating. The thickness of the coating is not limited, but is generally the same as that of a mold member described later.

[0009] Substantially hardening refers to a state in which the coating material hangs down and flows into a place where a concave portion is to be formed, so that the concave portion cannot be formed. Needless to say, it may be performed after it is completely cured.

The mold member covers the application surface so as to prevent the application material from being applied in order to form a concave portion, and usually has a thickness substantially equal to the application thickness. The material is
It is a polyolefin plastic. For example, polyethylene, polypropylene and the like. In addition, a foamed material is preferable, and a low foamed material of about 3 to 10 times is particularly preferable.

[0011] Silicone oil, which is the first feature of the present invention, is mixed in the plastic of the mold member.
Silicone oil is usually dimethyl silicone oil. A small amount of this (0.1
(About 3.0%). As a result, it becomes an internal release agent, and has considerably high releasability as compared with a plastic not added.

Further, instead of adding silicone oil, a silicone resin may be mixed with the above-mentioned plastic and molded. Even in this case, it becomes an internal release agent and exhibits release hardening for a longer period than the addition of the silicone oil.
In this case, it becomes a polymer alloy and is not copolymerized.
Therefore, the mixing amount is not particularly limited as long as it has compatibility.

The shape of the mold member may be any shape such as a narrow plate (rod), tape (winding type), curved shape, punched pattern, etc. It may be suitable for the recess. In addition, one recess may be formed by a plurality of mold members, and a plurality of recesses may be formed by one mold member. The thickness is preferably about 0.5 to 5 mm.
0 mm is also possible.

An adhesive may be applied to the back surface of the mold member so as to be attached to the work surface. Further, a release paper may be affixed thereon due to handling problems. Further, a reinforcing member (such as reinforcing paper) may be attached to the back surface or the front surface for reinforcing the mold member. This reinforcing member is removed when used.

[0015] A film may be attached to the surface of the main member to form a double structure (double joint material). In this, the mold member is placed and the coating material is applied from above,
The coating material is inevitably applied to the mold member. If the coating material cures in this state, the cured coating material must be removed when the mold member is removed, making it difficult to remove the mold member according to the shape of the mold member. For this reason, after the application material is applied, the surface film is removed at a stage where it is not yet cured. At this time, since it is not cured yet, it can be removed according to the mold member. Also, because it is a thin film,
There is no sagging problem. The thickness of this surface film is
About 0.05 to 0.3 mm is preferable.

After the coating material is hardened, the coating material is not already present on the upper surface of the mold member, and the side surface (the portion in contact with the coating material) of the mold member has sufficient releasability. The member can be removed.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the drawings. 1 and 2 show an example of a mold member for forming a concavo-convex pattern according to the present invention, which is used to form a joint pattern on a work surface.
It is sectional drawing. This joint member 1 for forming a joint pattern is obtained by laminating and unifying a release paper 3 also having a joint pattern formed thereon with an adhesive 4 on the back surface of a foamed polyethylene body 2 containing silicone oil having the joint pattern formed thereon. It is. The surface of the main body 2 is also covered with a covering material 5 having a joint pattern.
With an adhesive 6.

The joint pattern forming mold member 1 is composed of a release paper, a foamed polyethylene sheet containing silicone oil having an adhesive applied to the lower surface, and a thin plastic film (surface film) for coating having an adhesive applied to the lower surface. After laminating sequentially, it is easy to cut out unnecessary portions by using a punching machine or a laser beam or pressure water. In this case, only a portion other than the release paper may be punched by a punching machine. Alternatively, a plastic film, a foamed polyethylene sheet, and a release paper having a joint pattern punched in advance may be laminated and integrated with an adhesive.

Next, a method of forming a concavo-convex pattern using the joint pattern forming mold member 1 will be described. FIG.
(A) is an example of the joint pattern forming mold member 1, in which a release paper 3 is adhered to the back surface and a surface film 5 is adhered to the front surface. FIG. 3B shows a state in which the release paper 3 on the back surface is removed, the wall surface base 7 as the work surface is adjusted smoothly, and then placed thereon. If a waterproof paint or the like is spray-applied to the base, a part of the waterproof paint layer becomes a joint, so that if the paint is colored, the joint will also exhibit that color, and the appearance will be more excellent. Needless to say, the joints may be treated (waterproof or colored) after the mold member is removed.

Next, a spraying material 8 containing an acrylic resin emulsion as a main component as a coating material is uniformly sprayed on the wall surface (FIG. 3C). The spray amount may be determined by the thickness of the projection to be formed, that is, the thickness of the mold member 1. In addition, if a material in which a large amount of powder such as brick, porcelain, natural stone, or the like is mixed into the spray material 8 is used, an extremely realistic material can be obtained.

While the coating material 8 is not dried (from immediately after spraying to 1
After the time), only the surface film 5 is sequentially peeled off. Then, the coating material 8 adhered on the mold member 1
Are removed together to expose the foamed polyethylene surface (FIG. 3).
(D)). After the coating material 8 is sufficiently dried and solidified (for example, after about 24 hours), the mold member 1 is peeled off from the wall surface (FIG. 3E). In this case, since the coating material 8 on the surface of the mold member 1 has been removed in the previous process, no burrs are generated, and since the mold member 1 has sufficient peeling properties also on the side surfaces, it can be easily removed.

Although the process is now completed, a transparent paint such as acryl-urethane may be further applied to the entire surface to a uniform thickness. This transparent paint provides glazing, waterproofness and durability to the coating material and joints.

[0023]

The present invention described in detail above has the following effects. Since the mold member itself has releasability, it can be easily removed even after the coating material has solidified. In addition, the solidified coating material does not stick to the mold member and is removed, and a part of the mold member is fixed to the coating material and remains and does not impair the appearance. In order to obtain releasability, the trouble of applying a release agent is not required, and the cost can be greatly reduced. It is not washed off as compared with the case where the release agent is applied to the surface.
