この発明は無機質発泡粒積層板の製造法に関す
る。その目的は軽量、高断熱性であつて不燃建材
となし得る積層板の製造法を提案するにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing an inorganic foam granule laminate. The purpose is to propose a method for producing laminates that are lightweight, highly insulating, and can be used as noncombustible building materials.
黒曜石、真珠岩、松脂石、ひる石、シラス等の
発泡性鉱物粒は加熱すると発泡し、内部に独立気

および防水性を改善した積層板となし用いようと
する試みがある。 Expandable mineral grains such as obsidian, nacre, pinestone, vermiculite, and shirasu foam when heated, and become inorganic foamed grains with many closed cells inside. These foam particles have high heat insulating properties and are nonflammable, so they are attracting attention as heat insulating materials for building materials. These foam particles are fused to each other during foaming, or fixed using a binder to form a plate-shaped body, or the plate-shaped body is used as a core material and a surface material is laminated on the surface to improve strength and waterproofness. There are attempts to use laminates and plating materials.

積層板は発泡粒の粒間空隙に水や湿気の浸入が防
止できる。しかし発泡粒が相互に融着してなつた
板状体は脆弱であり、積層板となしても界面で剥

が破損し易い。また、有機質のバインダーを用い
たものは無機質発泡粒の不燃性を損ない、しかも
耐熱性、寸法安定性が劣る欠点があつた。 A laminated board made by laminating a surface material on the surface of a foamed grain plate can prevent water and moisture from penetrating into the intergranular spaces of the foamed grains. However, a plate-like body formed by mutually fusing foam grains is fragile, and even if it is made into a laminate, it is likely to peel off at the interface, and the foam grain layer is likely to be damaged by shear stress in the thickness direction. Furthermore, those using an organic binder impair the nonflammability of the inorganic foamed beads, and have the disadvantage of poor heat resistance and dimensional stability.

法にある。 This invention was made by focusing on the above-mentioned problems, and its gist is that water glass, a slow-release gelling agent,
Mix the foaming agent and water and perform foaming treatment to obtain a foaming ratio of 2.
A foamy substance more than twice as large as water glass,
It is characterized by mixing a water glass hardening agent and inorganic foam particles, solidifying it in a mold, forming it into a plate shape, and pasting and solidifying fiber cloth impregnated with water glass on both surfaces of this plate body. A method for manufacturing an inorganic foam granule laminate.
無機質発泡粒の原料としては黒曜石、真珠石、
松脂石、シラス、ヒル石あるいはそれらの混合物

ある。積層板は見かけ比重0.3〜1.0程度であり、
その寸法は通常60×240cm、90×180cm、厚さ10〜
70mm程度である。なお、原料発泡粒の粒径は黒曜
石で２〜15mm、シラスで10〜500ｍμ程度のもの
が一般に用いられる。 Raw materials for inorganic foam particles include obsidian, nacre,
You can choose from rosinite, shirasu, vermiculite or a mixture thereof. Among them, bulk density 0.1~0.5g/
ml of obsidian or shirasu foamed grains are suitable. The laminate has an apparent specific gravity of about 0.3 to 1.0,
Its dimensions are usually 60x240cm, 90x180cm, thickness 10~
It is about 70mm. Note that the particle diameter of the raw material expanded particles is generally 2 to 15 mm for obsidian and 10 to 500 m for whitebait.
表面材としてはガラス繊維クロス、合成繊維ク
ロス等の繊維クロス類を用い、水ガラスを含浸せ

ウム含水物（水ガラス１、２、３号）を用いる。
水ガラスは白色で平滑な面を形成できるので、美
粧性を損なうこともない。 Fiber cloth such as glass fiber cloth or synthetic fiber cloth is used as the surface material, and is impregnated with water glass and adhered and solidified. By impregnating and solidifying synthetic fiber cloth with water glass, it can be made to have physical properties similar to nonflammability. Also, as a water glass,
A hydrated sodium silicate (water glass No. 1, 2, or 3) represented by Na 2 O.nSiO 2 -XH 2 O is used.
Since water glass is white and can form a smooth surface, it does not impair the cosmetic properties.

性を損なうことなく均一に混合し、板状に成形す
ることを可能にする。 As the slow-release gelling agent, colloidal silica, monobasic calcium phosphate, magnesium diphosphate, etc. are used. These gelling agents enhance the stability and retention of the water glass foam, slow down the rate of increase in viscosity due to gelation, and can, for example, increase the gelation time to 2 to 3 hours or more. Therefore, the foam to which this slow-release gelling agent has been added takes a sufficient amount of time to foam to increase its foaming properties. It enables uniform mixing and molding into a plate without impairing foamability.

リン等の助剤を添加し板状に成形する。 Further, as a foaming agent, peptite, a synthetic surfactant, etc. are used, and as a curing agent, a silicate metal salt, magnesium biphosphate, etc. are used. In addition, in order to increase the volume and improve fire resistance, water resistance, or sound absorption properties, if necessary, auxiliary agents such as calcium silicate, alumina, and kaolin are added and formed into a plate shape.

Then, it is solidified in a mold and formed into a plate shape. Glass fiber cloth impregnated with water glass is adhered to both surfaces of this plate and solidified to form a composite plate.

る。 This invention consists of the above configuration. This manufacturing method uses water glass as a binder, which has a high affinity with inorganic foam beads, so it blends well with the surface of the foam beads and solidifies, firmly adhering the foam beads to each other and forming a plate-like body. The strength is significantly improved compared to fused foam particles. In addition, since the foam can be doubled or more without impairing its nonflammability, the weight of the plate-shaped body can be reduced, and at the same time, its heat insulation properties can be improved. Water glass, a slow-release gelling agent, a foaming agent, and water are mixed and foamed to form a foam with a foaming ratio of 2 times or more, and then water glass, a water glass hardening agent, and inorganic foam granules are added to the foam. Since the materials are mixed and formed into a plate-like material, it is possible to take sufficient time for foaming to increase the foamability and reduce the weight, and to control the specific gravity by adjusting the foaming ratio. The fiber cloth that is fixed and laminated on the surface of the plate is impregnated with water glass and adhered and hardened, so it can form a smooth surface with excellent cosmetic properties, and it becomes one with the underlying plate.
Demonstrates exceptional bending rigidity in laminates.
