Abstract: PROBLEM TO BE SOLVED: To homogeneously disperse a powder in a heat-insulating foam while causing the powder to perform its function and thus to obtain a heat-insulating foam improved in physical properties by using an apparatus comprising a means for mixing and stirring a reaction liq. comprising a plurality of liq. components. a means for supplying a powder, a means for wetting the powder with the reaction liq., and a means for delivering and foaming the reaction liq. contg. the wet powder. SOLUTION: According to the invention, even in the case of producing a heat-insulating foam by reacting a polyisocyanate and a polyol in the presence of water as a reactive blowing agent, cyclopentane as a volatile blowing agent, and a catalyst, a powder (e.g. NaOH, which has a function to adsorb CO2 gas generated by the reaction of water with an isocyanate) which adversely affects the storage stability of urethane materials can be used without inhibiting the generation of CO2 gas and thus without lowering the foaming efficiency. In the resultant foam, the powder which reacts with and fixes CO2 is homogeneously dispersed. Being filled with a volatile blowing agent having a low thermal conductivity, the foam has a low thermal conductivity.

Abstract: PROBLEM TO BE SOLVED: To prevent a carbonic acid gas-adsorbing effect from deteriorating with time after manufacturing a carbonic acid gas adsorbent by a method wherein an organic coat layer containing many hydrophilic groups in the inside of the coat layer, and many lipophilic groups outside the coat layer is formed on a surface of a power composed of an hydroxide of alkali metals hydroxide. SOLUTION: This carbonic acid gas adsorbent 1 used for improving a heat insulating property by decreasing a heat conductivity of a foam heat insulating material to be used for a refrigerator or the like, is formed by providing an organic coat layer 5 containing many hydrophilic groups 3 in the inside of a coat layer, and many lipophilic groups 4 in the outside of the coat layer to an alkali metals hydroxide 2. The alkali metals hydroxide 2 adsorbs and removes carbonic acid gas by reacting with the carbonic acid gas in the atmosphere, and a sodium hydroxide is mentioned therefor. When the organic coat layer 5 is applied thus, a water content in the atmosphere is restrained from penetrating into the inside of the coat by an effect of the lipophilic group 4, elution of alkali metals hydroxide or the like can be reduced, and the lowering of the effect as the carbonic acid gas adsorbent 1 can be prevented.
