DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to construction,
It can be used as an exterior wall material, roof material, ceiling material, floor material, partition material, fire door, etc., and has no deformation such as swelling or warpage after production, and has excellent fire resistance, fire resistance, and mechanical strength. It is about panels.

[0002]

2. Description of the Related Art In general, many fireproof panels in which a core material made of a phenol resin foam (phenol foam) is sandwiched between a thin plate-like front surface material and a back surface material have been invented, devised, and put on the market.

[0003]

However, in the above-described fireproof panel, the connecting portion structure is complicated.
In addition, the workability, such as around windows, was very poor due to the main structure being horizontal. Light, vertical, good workability,
JIS-A-1304 (Fire resistance test method for building structure)
No fireproof panel mounting structure was able to pass the fireproof structural test. Workability for large buildings was poor. The direction of construction was decided, and construction could not be performed on the left and right simultaneously. Replacement after construction was almost impossible, or very troublesome and dangerous work. There is no change in the makeup surface,
There was a problem with the appearance. Generally, when various types of synthetic resin foams are used as the core material, the mechanical strength of the panel itself is inferior, and due to the aging of the synthetic resin foam, irregularities or warping of the panel surface may occur. There were cases. During the formation of the core material, a reaction gas is generated and remains in the core material, or the phenol foam retains several tens of percent of the weight of the condensed water during the reaction. Later, due to changes in the outside temperature, etc., the water vaporizes and remains between the core material and the surface material or the back surface of the panel because there is no escape route, and gas swelling occurs on the back surface of the panel and the back surface of the back material. In some cases, the panel may be adversely affected with time, such as warping or warping. And the like.

Examples of the adhesive include an elastomer type epoxy resin, an isocyanate such as an emulsion type such as methylene diisocyanate (abbreviated as MDI), a hot melt type, and a modified isocyanate thereof such as a urethane-modified, a buret-modified isocyanate, and an isocyanurate-modified isocyanate. One type of isocyanate or the like is used, for example, an epoxy resin, a phenol resin, a urethane resin, a vinyl resin, an acrylic resin, a polyester resin, a synthetic resin adhesive such as an EVA resin, a rubber adhesive, an oil adhesive. , An ultraviolet-curable adhesive, or the like.

More specifically, the permeable member 25 may be any permeable member that forms a very small gap in the plastic foam 12, such as cotton, hemp, wool, and the like.
Fibers of silk and the like (vegetable fibers, animal fibers, synthetic resin fibers, inorganic fibers, and the like) are obtained by stretching a thin, long, and twisted fiber. More specifically, the air-permeable member 25
Is formed so that the excess gas components (chlorine, carbon dioxide, methylene chloride, formaldehyde, water vapor, hydrogen, etc.) in the plastic foam 12 or gases such as condensed water during the reaction can be passed through. There is no deformation such as swelling or warpage due to internal gas on the front and back surfaces of the fireproof panel A after manufacturing, and the fireproof panel A has excellent strength and fireproof performance.

At least one of polyester, cotton, silk, cotton, nylon, feathers, rock wool, various metals and the like is used, and is used as a thread or as a thin and long stretched fiber. Of course, the pile layer 26 using an inorganic material such as rock wool functions as a fire-resistant sheet.

The pile has an arbitrary diameter and a length of 1-2.
5 mm, thickness 10-200 denier, spray rate 10-3
The pile layer 26 is formed at 00 g / m ² . The pile has the root embedded and fixed in an adhesive, and its tip extends in the direction of the plastic foam 12. The direction may be any as long as it protrudes from the adhesive. It is preferable to be substantially perpendicular to the plastic foam 12 in order to strongly bond with the plastic foam 12. The pile is made of, for example, nylon as the material, the length is about 8 mm, the thickness is about 60 denier, and the scatter rate is 70.
By setting it to about g / cm ^2, the adhesive strength between the pile layer 26 and the plastic foam 12 can be increased.

A large number of piles are arranged on at least a part of the back surface side of the front surface material 1 or the back surface material 14 so that the pile layer 26 is formed.
Is formed, and penetrates into the liquid in the process of forming the plastic foam 12, and is hardened later to greatly improve the bonding strength between the front surface material 1 or the back surface material 14 and the plastic foam 12. In addition, it is intended to prevent the back material 14 from peeling off from the plastic foam 12 due to swelling and warping due to internal gas.

The pile layer 26 is formed by implanting a large number of piles before the adhesive applied to at least a part of the back surface side of the front surface material 1 or the back surface material 14 by a predetermined method does not dry. There are methods of mechanically directly planting a single unit or a plurality of units directly, and a method of spraying a pile on an adhesive.

The breathable fireproof sheet 27 is made of the non-combustible sheet 2.
It is made of the same material as that of No. 0, and the material having fire resistance is a sheet of inorganic fiber, such as rock wool felt, ceramic wool, glass wool, etc.
Alternatively, any material having air permeability may be used as long as it is an air permeable member that forms a very small gap between the plastic foam 12 and the space 2a. For example, cotton, hemp, wool, silk,
(Vegetable fiber, animal fiber, synthetic resin fiber, inorganic fiber, etc.). Of course, in this case, the breathable refractory sheet 2
The fiber No. 7 has the same operation and effect as the pile layer 26.
