make foam material. (3) Detailed & Invention The invention describes a method for producing a
foam material, more specifically, a method for producing a foam material in which foaming is
carried out at pH 3 with a monofunctional carbonate. In the past, structural materials such as
architectural materials requiring heat insulation or soundproofing-foam materials containing a
large number of microvoids have been used as structural materials-especially modern light
weight materials. The trend is promoting the practical use of various foam materials. For
example, urethane foam, expanded styrene, expanded polyethylene and the like are widely used
as a heat-radiating material or a structural part, such as KM ': C ". However, the biggest drawback
of the above-mentioned organic pond body is the shortcoming of the sea resistance in addition to
the lack of heat resistance], the absence of such Ha nature is the present structure One of the
fatal drawbacks to the use as materials O: As one of the main reasons for such combustible
continuum, methods of making inorganic materials into foams have been tried, such as foaming
as an example. There is sex concrete. However, even in the above-described example, although
the deflagration effect can be obtained, the method for forming the foam has a molding Sλ such
as requiring a special pressurized customer service. The inventor of the present invention
eliminates the above-mentioned drawbacks and has flame retardancy as well as heat resistance
and heat insulation, and as a result of intensive research on producing a multi-foam material
having characteristics of heat insulation tendency, gold EndPage: 1 bicarbonate Vortexing and
heating salt and / or metal bicarbonate and acid phosphate and / or acid phosphite in a specific
ratio to produce a very high quality foam material for harmful birds I found what I could get, and
reached the present wA. That is, the present invention (4) metal carbonate and / or metal
bicarbonate and (B'1 acidic acidic rinse ester / or acidic phosphorous acid ester. It is a method of
producing a multi-foam material, which comprises: I & summing at a ratio represented by a
weight ratio of Bm / Bm 0.2 to 10, and heating at normal temperature or higher IK. The metal

reaction of gold lA borate or metal bicarbonate with acidic substances to release carbon dioxide
gas, but also in such a case to keep a uniform, multi-cell-like soot in its open tube stable state. Is
extremely difficult. However, according to the present invention, a metal carbonate such as
calcium carbamoate or magnesium carbonate is treated with a specific ratio of acid phosphate
ester and / or acid phosphite ester and retained in the chamber 11 as necessary. The carbon
dioxide gas generated by heating at <RTIgt; C </ RTI> can be well dispersed and maintain the
shape of the multi-cell foam which is homogeneous at 91 Ikiit.
Moreover, the production of the multi-foam material does not require any special equipment, and
can be carried out safely and easily. (A: metal carbonate and / or metal bicarbonate and (f3. The
usage ratio of the acid phosphate ester EndPage: 2 and / or the acid residue is from 12 to 10 IIS
in weight ratio. In the case where the ratio of the above-mentioned ratio is less than the lower
layer, although the sufficient foaming is carried out 4, the shape of the multi-cellular material is
kept in a stable position due to excessive use of the component (2). Not On the other hand, when
used in a single unit where the ratio of mu / B exceeds the upper limit, uniform mixing of both
the body and the component (B) is difficult, and the resulting foam tends to be dull. Therefore, a
preferred weight ratio of -041 is in the range of 1 / 5-5. In the present invention, [4] is prepared
by mixing (4) metal carbonate salt and / or metal bicarbonate salt and (2) a hydrophobic
phosphate ester and / or acid sulfite at a specific ratio as described above. An acid gas is
generated, and the temperature applied at that time is the ratio of the above group / B, or the
monovalent Isa group constituting the component (B) (R, R in the above general formulas (1) to
