0 parts by weight Colorant (metal oxide)...0 to 20 parts by weight Binder (1'VA)...1 to 2 parts by weight.
If it is less than 0 parts by weight, it will not be made into porcelain, and if it is more than 80 parts by weight, the fire resistance will be too low and the shape cannot be maintained.
また、酸化アルミニュウム（アルミナ）は１０重量部よ
り少ないと抗折強度が低くなり、４０重量部以上では焼
成温度が高くなり、同時に経済性も良くない。Furthermore, if the amount of aluminum oxide (alumina) is less than 10 parts by weight, the bending strength will be low, and if it is more than 40 parts by weight, the firing temperature will be high, and at the same time, it is not economical.
また、ベントナイトは３重量部より少ない場合は成形性
が悪＜、３０重量部を越えると焼成温度が高くなる。Furthermore, if the amount of bentonite is less than 3 parts by weight, the moldability is poor, and if it exceeds 30 parts by weight, the firing temperature becomes high.
また、着色剤は２０重量部をこえると金属酸化物のため
磁器化しなくてなる。Moreover, if the coloring agent exceeds 20 parts by weight, it becomes a metal oxide and cannot be turned into porcelain.

本発明は上記の構成からなり、発泡剤である水ガラスが
、加圧成形後の加熱焼成によって独立起泡を断熱材の全
体に亘って均一に形成するため、断熱材は軽量で、機械
的強度が大きく、かつ断熱効果が高い特許を持つ。The present invention has the above-mentioned structure, and the foaming agent, water glass, uniformly forms independent foam throughout the insulation material by heating and baking after pressure molding, so the insulation material is lightweight and mechanically stable. It has a patent for its high strength and heat insulation effect.
また、同時に穴あけや切断等の取付現場における加工作
業がしやすくなる等の特長がある。At the same time, it also has the advantage of making it easier to perform processing operations such as drilling and cutting at the installation site.

段とｆｆ’ｉｆｆ！かつ安価にできるのは勿論のこと、
美観や耐久性の点についても優れた断熱材を作ることが
できる特長がある。In addition, in the method of impregnating water glass into an arbitrary thickness or predetermined part of a pressure-molded body, the substrate and foam are welded and integrated by heating and baking, so glass wool or rock wool is used as an adhesive. Compared to conventional thermal insulation materials (building materials) that are bonded to the surface, the manufacturing process is much more ff'iff! And of course it can be done cheaply,
It has the advantage of being able to produce insulation materials that are excellent in terms of aesthetics and durability.
また、ｖ＃熱材の裏面側を接着面とした場合その裏面の
表面が発泡によって一様に粗面化されているため接着材
であるモルタルやセメントとの親和性がよく接着強度が
高くなって施行がしやすくなる特長がある。In addition, when the back side of the v# thermal material is used as the adhesive surface, the back surface is uniformly roughened by foaming, so it has good compatibility with the adhesive mortar and cement, resulting in high adhesive strength. This has the advantage of making it easier to enforce.
