CONSTITUTION:This material is produced by mixing a blowing agent (A) (e.g. ammonium polyphosphate), a synthetic resin (B) (e.g. a melamine resin), a carbon-generating agent (C) (e.g. pentaerythritol), an inorg. powder (D) (e.g. a titanium oxide powder), and a glass frit (E) having a softening point of 700-1,000 deg.C (e.g. a borosilicate glass) and adding some water to the resulting mixture. Pref. 10-200 pts.wt. component E is used based on 100 pts.wt. component D, and the sum of components D and E is pref. 10-40wt.% of the sum of components A, B, C, D, and E. Component E is pref. in the form of particles having an average particle side of 10mum or lower. The obtd. expandable fire- resistant coating material is suitable for coating a steel frame of a building, etc.

摘要： PURPOSE:To obtain a ceramic circuit board, in which a ceramic board and a conductor pattern are not peeled after baking, by using the mixed powder of Ag powder and PdO powder as powder for forming the conductor pattern. CONSTITUTION:Powder in which 65-95 pts.wt. Ag powder and 5-35 pts.wt. PdO powder are mixed is employed as powder for forming a conductive pattern. Powder having approximately 0.3-10mum mean particle size normally used as a conductor material can be employed as Ag powder and PdO powder. It is favorable because Ag-PdO powder acquired is mixed uniformly and the conductive pattern is shrunk equally that not more than 2mum Ag powder and PdO powder are used particularly. The Ag powder and PdO powder are mixed through a conventional means, thus manufacturing a powder composition for forming the conductive pattern.

摘要： PROBLEM TO BE SOLVED: To prevent a foamy fire-proof paint film layer from hanging-down in the rise of tempersture by forming a cover material layer on the surface of the foamy fire-proof paint film layer to maintain the covering condition until the foamy fire-proof layer paint film layer is foamed and form a cover material layer which does not hinder the foaming. SOLUTION: A cover material layer which maintains the covering condition until a foamy fire-proof paint film layer is foamed and does not hinder the foaming is formed on the surface of the foamy fire-proof paint film formed on the surface of a steel skeleton post or beam. Thus, since the foamy fire-proof paint film layer softened before the foaming is supportively sandwhiched between the cover material layer and the surface of a steel skeleton post or the like, the paint film is prevented from the hanging-down caused by its own weight. The foamy fire-proof paint film layer prevented from the hanging-down by the cover material layer is foamed in its own position to form a perforated adiabatic layer with uniform thickness, so that sufficient fire-proof performance is provided.
