Description

[Detailed description of the invention] The present invention relates to a construction board material, and its purpose is to provide a construction board material that has excellent heat insulation and workability, is inexpensive, and has a performance that is at least semi-incombustible. The purpose is to

The present invention will be explained in detail below based on the illustrated embodiments.

The base material 1 is mainly composed of asbestos mixed with waste material from asbestos sheet manufacturing (styrene-butadiene rubber or acrylonitrile-butadiene rubber, for example, 86% asbestos mixed with 14% acrylonitrile-butadiene rubber).

) were collected and re-pressed to a thickness of approximately 3 mm, drained, and crimped to give smoothness.

A decorative layer 2 is adhesively laminated on the surface of this base material 1.

The decorative layer 2 is, for example, printed solidly on 23 g/m thin paper to give concealment properties, then printed with a wood grain pattern such as a cedar pattern, and finally overcoated with aluminum alkyd paint. After applying vinyl acetate adhesive (CH-18, manufactured by Konishi Giske Co., Ltd.) to the surface of the base material 1 at a rate of 8 g/2 cm using It is processed and laminated.

Since the base material 1 of the construction board material obtained in this way is mainly composed of asbestos, it has properties that are more than quasi-incombustible. A frame 5 with actual processed parts 3 and locust processed parts 4 on both sides having the dimensions (mm) shown is integrated on the back side of the base material 1, and a heat insulating material such as polyurethane foam or glass wool is placed inside the frame 5. 6 may be filled.

In this invention, a decorative layer is laminated on a base material made from waste materials from asbestos sheet manufacturing such as diagonal sheets, so the base material has asbestos as its main component and has more than quasi-incombustible performance. Since it uses waste materials from asbestos sheet manufacturing, it has the advantage that it can be manufactured at low cost.

In addition, the back of the base material has an actual processed part and a locust processed part on both sides, and the inside is filled with heat insulating material to integrate the frame, so compared to a decorative board that simply uses asbestos sheets, the frame is The heat insulating properties can be enhanced by the heat insulating material that is sufficient for the frame, and since there are actual processed parts and locust processed parts on both sides of the frame, adjacent building boards can be easily joined together. , has the advantage of not only the above-mentioned heat insulation properties but also excellent workability.

[Brief explanation of the drawing]

The drawing shows a sectional view of an embodiment of the present invention, in which 1 is a base material, 2 is a decorative layer, 3 is an actual processed part, 4 is a locust processed part, and 5
is a frame, and 6 is a heat insulating material.
