It has excellent waterproof, moisture-proof, heat-insulating, and sound-absorbing properties, and is widely used as a base material for buildings and structures as a lightweight member. However, now that fire resistance has become an essential requirement for building materials, some measures are being taken, such as mixing foams with foamable inorganic materials. but,
The foam produced by this method has no established equipment or technology for uniformly distributing the foamable inorganic material within the foam, resulting in uneven distribution of the foamable inorganic material and areas lacking fire retardant properties. arise. ○The foam structure of Roform is damaged by the foamable inorganic material, which increases the amount of resin used, leading to increased costs and decreased insulation properties. ○The chemical reaction during hafoam production is changed by the addition of foamable inorganic materials.
○D) There were weaknesses such as the fact that the foamable inorganic material existed in pieces within the foam, so it did not function effectively as a protective layer.

は少なく含浸することも可能である。 An embodiment of the base plate according to the present invention will be described in detail below with reference to the drawings. That is, the present invention is a base plate in which at least one side of a foam 1 is laminated with a gypsum-impregnated nonwoven fabric 3 impregnated with a foamable inorganic material 2, as shown in FIG. To explain further, Form 1 is mainly used for insulation, waterproofing, cushioning,
Functions as sound absorbing material and core material. Specific examples include polyurethane foam, polyisocyanurate foam, polystyrene foam, polyethylene foam, and vinyl chloride foam.
Note that the density and thickness of the foam 1 are selected depending on the purpose. There are two methods for forming the foam 1: cutting the molded body into a predetermined shape or forming the raw material into a foam by a so-called in-situ foaming method, and preferably the latter method is used. The above-described foamable inorganic material 2 serves only as a fire retardant. In particular, when the foamable inorganic material 2 is exposed to high temperatures, it releases crystal water and gradually cools the surrounding area, and at the same time, it melts and evaporates water, gradually becoming viscous and achieving a balance between vapor pressure and viscosity. The foam expands to form an inorganic foam layer that is nonflammable and has heat insulating properties. Specific examples thereof include one or more of borax, sodium metaborate, 4-9 sodium borate, beryum borate, sodium silicate, sodium metasilicate, and sodium orthosilicate. In addition, gypsum-impregnated nonwoven fabric 3
is a porous sheet-like material whose main component is gypsum, which is combined with a synthetic resin binder and nonwoven fabric. In addition, the gypsum-impregnated nonwoven fabric 3 impregnates and holds the foamable inorganic material 2, and the gypsum-impregnated nonwoven fabric 3
Due to its own nonflammability and fire resistance, and the inorganic foam layer of the foamable inorganic material 2, the foam 1 is protected at high temperatures and its fire resistance is improved. That is,
The gypsum-impregnated nonwoven fabric 3 holds the foamable inorganic material 2 on the entire surface of the foam 1, allows the inorganic foam layer to be uniformly formed on the foam 1 at high temperatures, and acts as a skeleton of the inorganic foam layer to prevent cracks. , to prevent peeling. In addition, since the gypsum-impregnated nonwoven fabric 3 itself is a nonflammable material and gypsum contains crystal water, the foamable inorganic material 2 melts and
It also functions as a fireproof layer until foaming, making it possible to further strengthen fire resistance. Furthermore, since the gypsum-impregnated nonwoven fabric 3 is porous, it adds sound absorption and vibration damping effects to the base plate. The thickness of the gypsum-impregnated nonwoven fabric 3 is 4 to 6 mm, and the density is 800 to 1200 g/
It is of m2 . In addition, the amount of the foamable inorganic material 2 to be impregnated into the gypsum-impregnated nonwoven fabric 3 is 400 to 2000 depending on the purpose.
g/ m2 . Of course, it is also possible to impregnate more or less than this.

Form 1 is a polyisocyanurate foam with a thickness of 15 mm and a density of 40 Kg/m 3 , foamable inorganic material 2 is sodium metaborate, gypsum-impregnated nonwoven fabric 3 is a 4 mm KG sheet (manufactured by Kuraray Co., Ltd.), and backing material. A sheet of asbestos paper (0.15 mm thick) laminated with aluminum foil (0.1 mm thick) was used as the material. In addition, the impregnated amount of foamable inorganic material 2 is 1200
g/ m2 . Therefore, when this base plate was directly exposed to a flame of 900°C for 10 minutes from the direction of the gypsum-impregnated nonwoven fabric 3, the temperature of the back surface was 180°C. Also, when this base plate is disassembled and observed,
The KG sheet used as the gypsum-impregnated nonwoven fabric 3 becomes the skeleton of the inorganic foam layer, which is held uniformly on the surface of the foam 1. The inorganic foam layer protects the foam 1 from fire without cracking or peeling, and prevents further heat conduction and intrusion. was completely blocked. Furthermore, when the base plate thus manufactured was subjected to a quasi-inflammability test according to JIS-A-1321, it showed sufficient performance to pass.
