JPH10151405A - Method for working surface of formed polystyrene - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the generation of cracks, to reduce weight, and to materialize prescribed strength by a method in which the surface of formed polystyrene is covered with a glass fiber mesh, and a substrate material in which an acrylate and cement the amount of which is a specified wt.% of the acrylate are mixed and agitated is applied or sprayed on the mesh, dried, and solidified. SOLUTION: The surface 2 of a base material 1 of polystyrene foam which was cut in a prescribed shape using a heating wire is covered with a glass fiber mesh 3 in which glass fibers are spread in a mesh shape. A substrate material 4 in which 10-20wt.% of cement powder is mixed into a liquid acrylic resin is agitated, applied on the mesh 3 by troweling or spraying, dried, and solidified to form a coating layer 5. A decorative finishing agent 6 is applied or sprayed on the layer 5 to form a prescribed decoration. In this way, the generation of cracks is prevented, weight is reduced, prescribed strength can be materialized, and work efficiency can improve.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a surface of polystyrene foam.

[0002]

2. Description of the Related Art Conventionally, for example, decorations for decorating upper portions of pillars and beams, such as balconies, are made into a mold, and plaster is poured into the mold and molded into a predetermined shape. Had been mounted in position. However, the above-mentioned conventional method increases the cost for making the mold,
Since the construction period is long and the weight is large, there is a drawback that a large number of people and labor are required for installation.

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to coat the surface of styrofoam with a glass fiber mesh and a base material, and to apply a predetermined amount to the base material. In order to provide a new method of applying a surface of a new styrofoam having a light and predetermined strength so as to have a strength and to have flexibility by using a glass fiber mesh so as not to cause cracks and the like. is there.

[0004]

In order to solve the above-mentioned problems, the present invention provides a method for applying a surface of styrofoam to cover the surface of styrofoam with a glass fiber mesh, and apply acrylic on the glass fiber mesh and 10 to 10% of the acrylic. It is characterized in that a base material mixed with 20% by weight of cement and stirred is applied or sprayed and dried to be solidified.

[0005] Further, at least one coating layer comprising a glass fiber mesh and a base material is further formed on the solidified base material.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 5 are views for explaining a method for applying a surface of a polystyrene foam according to the present invention. In the drawing, reference numeral 1 denotes a base material made of, for example, styrofoam cut and formed into a predetermined shape using a hot wire, and a glass fiber mesh 3 in which glass fibers are made into a Nash shape is formed on a surface 2 of the base material 1. Placed on the base material 1 and the glass fiber mesh 3
Is applied by ironing or spraying. The base material 4 is composed of 10 parts of powdery cement in liquid acrylic resin.
２０20% by weight was mixed and stirred. In addition, you may mix sand with this as needed.

When the undercoating agent 4 is dried in this state for about one day and night, the undercoating agent 4 is solidified and the coating layer 5 is formed. In this state, the base layer 4 is solidified, so that the coating layer 5 is hard and has strength. Further, the glass fiber mesh 3 has flexibility due to the action of the glass fiber mesh, and therefore, for example, cracks do not occur even when a plate-like styrofoam is bent. The decorative finish 6 is applied or sprayed thereon to form a predetermined decorative product.

If it is necessary to further increase the strength, a coating layer 7 made of a glass fiber mesh 3 and a base material 4 may be further provided on the coating layer 5 as shown in FIG. Of course, the coating layer is 2-3
Layers and multilayers may be used.

FIG. 5 is a view showing an example in which the present invention is applied to decoration of an outer wall of a building. The decoration 11 shown in FIG.
The decoration 11 is attached to the outer wall 8 using an adhesive so as to surround the entrance 14 provided in the outer wall 8.

In the above description, the decoration of the outer wall of a building has been described as an example. However, since it is possible to make a predetermined shape easily, inexpensively and in a short time, for example, a theater, It can be widely applied to things that constitute a background that is used for a short time on a stage or a television studio, and other decorations and ornaments. Further, when the surface shape of the ornament or the like is complicated, it may be better not to use the glass fiber mesh 3, but this does not cause any particular problem.

[0011]

According to the styrofoam surface construction method according to the present invention, the following effects can be obtained because of the above-described configuration. (1) Since the base material has the same strength as mortar when dried, it becomes a light and strong material. In addition, the use of the glass fiber mesh has flexibility, so that cracks hardly occur.

(2) Since the interior is made of styrofoam, it is light and easy to carry in and carry out, so that work efficiency is improved. (3) Since cutting is easy, site adjustment is extremely easy.
