The present invention relates to a molding for construction using a phenoxy resin and a manufacturing method thereof. Such building moldings are used in paneling, bricks, and boards, for example, in partitions and interior building materials such as apartments, houses and offices.

As a conventional molding for this kind of construction, there is a thing described in JP 57-112519. The partition structure described in this publication is composed of non-flammable plate-like bodies such as asbestos, paper, and thread, and the inside surface is light and insulated by using polyurethane, polystyrene, polyethylene, and PVC foam as insulation material. And soundproof is obtained.

However, such a partition structure is harmful to the human body because the non-flammable exterior material is composed of asbestos, and the inside is made of combustible synthetic resin, so it is always risky because it burns well in the fire, and it is not economical because it is expensive. .

Therefore, an object of the present invention is to provide a prefabricated lightweight building material that does not use asbestos and combustible synthetic resins, which is harmless to the human body and significantly reduces damage from fire, and also has excellent thermal insulation and soundproofing effects.

The present invention has been made in order to achieve the above object, and mixed between the acrylic emulsion zone resin in order on both surfaces of the honeycomb foam 10 filled with a phenolic resin or a phenoxy resin and a foaming agent inside the honeycomb 12 and foamed and filled. It is characterized by a building molding in which the resin concrete material 20, the sheet 30, and the non-combustible exterior material 40 are integrally formed.

According to another aspect of the present invention, (a) a step of forming a honeycomb foam 10 filled with a phenolic resin or a phenoxy resin and a foaming agent and foamed and filled in the honeycomb 12, and (b) the honeycomb resin foam 10 It is characterized by the building molding which formed the resin concrete material 20, the sheet | seat 30, and the non-combustible exterior material 40 which integrated acrylic emulsion zone resin on both surfaces of ().

According to another aspect of the present invention, (a) a step of forming a honeycomb foam 10 filled with a phenolic resin or a phenoxy resin and a foaming agent and foamed and filled in the honeycomb 12, and (b) the honeycomb resin foam 10 Acrylic emulsion resin coated resin concrete dough on both surfaces of the sheet and placed sheet 30 thereon, (c) on each sheet 30, gravel, sand, cement and water. A building molding comprising a process of applying the mixed concrete composition, and (d) curing the laminate composed of the steps (a), (b), and (c) in an air or warm state to form the laminate integrally. Characterized in that the manufacturing method.

According to the configuration of the present invention, since the honeycomb-shaped honeycomb inside is completely foamed and filled with a phenoxy resin, the honeycomb resin foam is used so that the insulation and soundproofing effect are not burned while maintaining the strength without inherent deformation. Excellent weight and light weight makes it very easy to move.

The present invention will be described in more detail as follows.

1 is a schematic perspective view showing a part of the construction of the building panel according to the present invention.

First, the resin concrete material 20, the sheet 30, and the non-combustible exterior material 40 are integrally formed on one surface of the honeycomb resin foam 10 in which the phenoxy resin and the foaming agent are foamed and filled in the honeycomb 12. To form. Other surfaces of the honeycomb foam 10 are integrally formed with the same structure as above.

The honeycomb 12 can be used according to the application regardless of the size and shape of the cell, and any one can be used, and a commercially available one made of paper is usually used.

The honeycomb 12 is a foamable synthetic resin, for example, a resin such as polystyrene, polyethylene, polyurethane, etc. can all be used, but because it burns well, the present invention does not use them, and is a hardenable synthetic resin that does not burn well. , Phenoxy resin is used.

When the phenoxy resin and the blowing agent are mixed into the honeycomb 12 and naturally foamed by self-heating in the air, a honeycomb resin foam 10 having excellent compressive strength is produced.

Honeycomb was used to hold the foam in FIG. 1, but as shown in FIG. 2, a support rod may be formed to prevent deformation of the foam layer.

In this way, the honeycomb resin foam 10 is manufactured and the acrylic emulsion resin and, for example, sand and cement are placed on the workbench (not shown) to form the resin concrete material 20. Concrete such as concrete is mixed and kneaded, the dough is applied to an appropriate thickness according to the use, and the sheet 30 is laid thereon and attached thereto.

Subsequently, in order to form the non-flammable exterior material 40 on the sheet 30, concrete components such as gravel, sand, and cement (including back cement) are used to vary the thickness according to the purpose and the purpose thereof.

In addition, the other surfaces of the honeycomb resin foam 10 are sequentially applied in the same manner as described above, and then curing or aging these coated and laminated laminates to harden integrally to form the panel 1, which is a desired building molding. do.

The non-female exterior material 40 may further add pigments to concrete components, and then polish or surface (including enamel) treatment according to the purpose of use to obtain the same texture and aesthetic as natural stone.

For example, when used for simple partitions such as houses or apartments, the surface of non-combustible exterior materials is only polished, and when waterproofing such as toilets or kitchens is required, the surface is coated and waterproofed or indoors such as hotels and offices. If you want to enhance the atmosphere, you can add pigments to create a beautiful natural effect.

Examples of the sheet used in the present invention include glass fiber nets, wire nets, nylon nets, and nonwoven fabrics containing chloroacrylamide resins. These materials are selected according to the purpose of use and the purpose of use.

For example, a fire resistant sheet is used for indoor use. They are used to reinforce the strength of concrete and to give durability by reinforcing fractures and cracks. That is, the panel 1 functions as a kind of reinforcing core so as not to be broken or broken when broken by an external impact.

As described above, the present invention maintains excellent heat insulation, sound insulation and volume stability by using honeycomb and phenoxy resin, and can greatly reduce the weight of the product.

In addition, the use of resin concrete mixed with synthetic resin maximizes the bond between sheet and concrete while simultaneously providing flexibility and waterproofness to induce perfect adhesion with phenoxy foods.

In addition, by forming a non-combustible exterior material it is possible to obtain a building molding, such as panel, brick, etc., beautiful color and excellent texture like natural stone.

It is also possible to manufacture the brick 100 as shown in FIG. 4 in the same manner as the production of the panel.

(A), (b), and (c) show another embodiment of the present invention, that is, brick, (a) is a perspective view showing the case of using the present invention as a brick, (b) (a) AA line sectional drawing of (), (c) shows the cross-sectional view of (a). 5 is a view showing another embodiment of FIG.

Here, the difference between the panel and the brick is that the brick seals the honeycomb resin foam with a mixture of acrylic emulsion-based resin and back cement.

In the figure, reference numeral 114 is an adhesive such as cement, resin, resin mixed concrete, and 102 is a barrier material.

Although only the panel and brick of the present invention have been mentioned, it can be used as various insulation and sound insulation.

EXAMPLE
