本発明は金属基板上に異種発泡体を積層し、かつ裏面に
断熱性ガラス質発泡層を形成せしめることにより耐火性
、耐熱性、保温性に優れ、しかも軽量建築用材として有
用な異種積層発泡体の製造法に関する。Detailed Description of the Invention The present invention is a lightweight construction material that has excellent fire resistance, heat resistance, and heat retention by laminating different types of foam on a metal substrate and forming an insulating glass foam layer on the back side. The present invention relates to a method for producing a heterogeneous laminated foam useful as a material.
従来、断熱材として珪酸塩類を主成分とし、これに樹脂
を加えた発泡成形体はよく知られている。BACKGROUND OF THE INVENTION Foamed molded articles made of silicates as a main component and resin added thereto as a heat insulating material have been well known.
しかしながら、この種発泡体は極めて脆弱であり、しか
も耐水性、および耐熱性（約７４０’ｔ；位）に欠ける
ため殆んど実用化されていないのが現状である。However, this type of foam is extremely fragile and lacks water resistance and heat resistance (approximately 740'T), so it is hardly ever put into practical use.
本発明は上記したような欠点を除去すると共に、製造が
極めて容易で、かつ外部の熱に対して充分な耐火性、耐
熱性を有する異種発泡積層体の製造法を提案するもので
ある。The present invention eliminates the above-mentioned drawbacks, and proposes a method for producing a heterogeneous foam laminate that is extremely easy to produce and has sufficient fire resistance and heat resistance against external heat.
以下に、図面を用いて本発明に係る異種積層発泡体の製
造法について詳細に説明する。EMBODIMENT OF THE INVENTION Below, the manufacturing method of the heterogeneous laminated foam based on this invention is demonstrated in detail using drawings.

砂を加熱発泡させたものである。FIG. 1 shows a cross-sectional view of a heterogeneous laminated foam according to the present invention, in which 50 to 200 parts of powdered sodium silicate and 50 parts of pearlite in a range of 150 to 200 meshes per 100 parts of polyurethane resin are placed on a metal substrate 1. 200 parts of powdered borax Na2B40 10
Several layers of H2Q or partially dehydrated Na2B4O7-3 are applied, and then pressure is applied to heat and foam the borax to about 80 to 150 inches.
さらに説明すると、上記粉末珪酸ソーダを１５０〜２０
０メツシユに限定したのは粒子が細い程ポリウレタン樹
脂との混合が良く、したがって１５０メツシュ以上の細
いものとした。To explain further, the above powdered sodium silicate is added at 150 to 20%
The reason why the mesh was limited to 0 mesh was because the thinner the particles, the better the mixing with the polyurethane resin, so the mesh was set to be 150 mesh or more.
しかし２００メツシュ以上細いものは一般に粒子状にす
るのに特別の配慮、すなわち作業上、設備上の問題もあ
ると同時に定形発泡体を作ることが困難となるからであ
る。However, if the material is thinner than 200 meshes, special care must be taken to make it into particles, ie, there are problems in terms of work and equipment, and at the same time, it is difficult to make a shaped foam.
また、珪酸ソーダ、硼砂、パーライトの添加量を前記の
ように限定したのは、所期の耐火耐熱性を得るのに必要
であることによる。Further, the addition amounts of sodium silicate, borax, and pearlite are limited as described above because they are necessary to obtain the desired fire and heat resistance.
なお、不定形発泡体３は硼砂が不定形に発泡して、この
不定形物が互に連続した断熱ガラス質発泡層を形成した
ものである。The amorphous foam 3 is made by foaming borax into an amorphous shape, and the amorphous material forms a continuous heat-insulating vitreous foam layer.

層が断熱、耐火性を発揮し、定形発泡体２を保護するも
のである。By continuously forming this insulating vitreous foam layer on the back side, the vitreous foam layer on the back side exhibits heat insulation and fire resistance against external heat, and protects the shaped foam body 2. .
次に実施例につき説明する。Next, an example will be explained.

A mixture of 200 parts of powdered sodium silicate and 50 parts of perlite, which has a mesh size of around 0.0 mesh, is laminated, and an average of
Borax powder granules consisting of mesh before and after were spread and pressed to form a layer, and then foamed at a temperature of 80-150-U.
得られた成型板は非常に軽く、かつ、不定形発泡体３側
