(Industrial Application Field) The present invention relates to a foaming resin composition that provides excellent flame retardant properties of the resulting foam and excellent liquid fluidity during foaming. (Prior art) Recently, flame retardant requirements for building materials, especially residential exterior wall materials, have become more stringent, and a model box test No. 1372 has been added to the Ministry of Construction notification No. 1231 semi-flammability test. It came to this. The Ministry of Construction Notification No. 1372 model box test refers to the afterflame in the same No. 1231 quasi-noncombustible test.
It is a very demanding process that requires meeting the regulatory values for temperature, time, area, and smoke production coefficient, then increasing the size of the test specimen and determining the amount of heat generated during combustion and the shape after combustion.
Structures using conventional isocyanurate foam (a type of polyurethane foam) having isocyanurate rings made from industrial polyol as a raw material undergo significant shape change after combustion and have a large calorific value, so the above-mentioned No. 1372 Passing the model box test is difficult. On the other hand, structures using known phenol foams do not change their shape after combustion, but have the disadvantage of a long afterflame time after combustion. When switching manufacturing equipment that has been conventionally used for molding isocyanurate foam (a type of polyurethane foam) having isocyanurate rings to molding phenol foam, the heating device during and after foaming must be heated to high temperature. In addition, it is necessary to change to a device that can heat for a long time, and the method for producing phenol foam using this device is also extremely inefficient. On the other hand, structures using foams made from carbohydrates have improved flame retardancy compared to structures using isocyanurate foams made from industrial polyols. Due to its poor properties, it is difficult to fill the edges during panel manufacture, and only a high-density foam can be obtained, resulting in high costs and poor productivity. (Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned problems, and takes advantage of the excellent workability of polyurethane foam to provide a foam that has excellent flame retardant properties and An object of the present invention is to provide a foaming resin composition having excellent liquid fluidity. (Means for Solving the Problems) The present invention provides an aqueous solution and/or slurry of carbohydrates, a reaction catalyst, an isocyanate compound, a methyl group bonded to silicon,

(b)[Formula] Where Y is the number of moles of units and Z is the number of moles of (-CH 2 CH 2 O)- units, those in which Y+Z/X=0.5 to 11 and Y/Z=0 to 1.8 are used. If X, Y and Z are outside the above ranges, the fluidity during foaming will be poor. More preferably, Y+Z/X is in the range of 0.5 to 11 and Y/Z is in the range of 0 to 1.0. Examples of such silicone foam stabilizers include those represented by the following formula. In the above formula, R is an alkylene group, R' is an alkyl group, etc., and m, n, Z, and Y are 0 or a positive number. The silicone foam stabilizer used in the present invention includes TFA-4200 manufactured by Toshiba Silicone Corporation;
TSF-4452, TFA-4310, TSF-4445, SZ-1605, SZ-1623, SZ- manufactured by Nippon Unicar Co., Ltd.
1610, F-318, F-341 manufactured by Shin-Etsu Chemical Co., Ltd.
There are F-347, F-350S, etc. Number of moles of each segment of silicone foam stabilizer X,
Y and Z are usually measured by NMR spectroscopy. If the peak of the methyl group of tetramethylsilane is 0 ppm, (a) the peak of the methyl group bonded to silicon is 0.05~
Since it appears at 0.30 ppm, X is the value obtained by dividing the integral value of this peak by the number of protons in the methyl group, which is 3. (b)

Since a CH 2 peak appears at 3.90 ppm, Z is the value obtained by dividing the integral value of this peak by the number of protons, 4. The values of Y+Z/X and Y/Z are determined from X, Y, and Z obtained as described above. Flame retardants used as necessary in the present invention include organic flame retardants such as tris(2-chloroethyl) phosphate, tris(2-chloropropyl) phosphate, chlorinated paraffin, hexabromobenzene, antimony trioxide, and water. There are inorganic flame retardants such as aluminum oxide, and these can be used alone or in combination. Isocyanate compounds in the present invention include tolylene diisocyanate, hexamethylene diisocyanate, isophorone diisocyanate, diphenylmethane-4,4'-diisocyanate, polymethylene polyphenyl isocyanate, mixtures thereof, derivatives of these isocyanates, etc., and purified or crude Any isocyanate compound can be used, and monoisocyanate compounds such as phenyl isocyanate can also be used in combination. In addition, when building a structure using the foaming resin composition of the present invention, a flame-retardant or non-combustible plate or sheet is provided on at least one side of the foam obtained from the resin composition. Or sheets include aluminum kraft paper, metal foil such as aluminum foil, copper foil, aluminum asbestos sheet, wood wool cement board, iron plate, steel plate, stainless steel plate, aluminum plate, metal plate such as copper plate, slate plate, calcium silicate plate. , inorganic noncombustible boards such as gypsum board, cement board, and glass fiber reinforced cement board. These flame-retardant or noncombustible boards or sheets may be painted for reasons such as appearance or corrosion prevention. It is necessary to carefully consider the material or thickness of the paint film used for the paint so as not to reduce its flame retardance, but as long as the paint film is thin, there is no particular restriction on the material, and usually commercially available colors can be used.

After 10 minutes, the mold was removed to obtain a flame-retardant structure in which a colored iron plate (0.27 mm thick) was adhered to the surface of the foam (15 mm thick), and aluminum kraft paper was adhered to the back side. The density of the foam, which is the core material of this structure, is 0.024g/cm 3 , and the water absorption amount at each end is 90g/cm 3 .
The foam had a uniform and fine cell structure, and was comparable to conventional foams in terms of water absorption and fluidity. Table 1 shows the results of a nonflammability test conducted on this structure based on Ministry of Construction Notification No. 1231. As is clear from Table 1, this structure has an external appearance after combustion, an afterflame, a smoke generation coefficient,
It was extremely excellent in terms of temperature coefficient and temperature time area. This structure also had excellent adhesion to colored iron plates and aluminum kraft paper. Example 2 75 parts by weight of fructose, 25 parts by weight of tap water, 1.0 parts by weight of the silicone foam stabilizer used in Example 1, nonionic surfactant (manufactured by NOF Corporation, trade name: Nonion NS-

Add the weight parts and mix by stirring at 2000 rpm for 5 seconds using a stirrer equipped with a turbine blade.Then, do the same as in Reference Example 1 and place a color iron plate on the surface of the foam (thickness 15 mm) and an aluminum plate on the back side. A structure with kraft paper glued was obtained. In this case, the panel filling property of the foam is 5 points, the foam height is 350 mm, the flow distance is 225 mm, the density of the foam is 0.026 g/cm 3 , the water absorption at the end is 130 g/m, and it has a uniform and fine cell structure. It was foam. In addition, Table 1 shows the results of a semi-flammable test conducted on this structure based on Ministry of Construction Notification No. 1231.
As is clear from Table 1, the amount of water absorbed at the end was larger than that of Reference Example 1, but the same results were obtained in fluidity and flame retardance. Comparative Example 1 1.5 parts by weight of triethanolamine was added to 75 parts by weight of fructose and 25 parts by weight of tap water and mixed well to obtain a solution D. Diphenylmethane diisocyanate (manufactured by Nippon Polyurethane Co., Ltd., trade name Millionate MR-100)

Add 150 parts by weight of solution E to 100 parts by weight of solution D, stir and mix for 5 seconds at 2000 rpm using a stirrer equipped with a turbine blade. A structure was obtained with a colored iron plate attached to the top and aluminum kraft paper glued to the back. In this case, the panel fillability of the foam is 2 points, the foam height is 290 mm, the flow distance is 180 mm, and the foam density is
The foam had a uniform and fine cell structure with a water absorption of 0.035 g/cm 3 and an end water absorption of 100 g/m. In addition, Table 1 shows the results of a semi-flammable test conducted on this structure based on Ministry of Construction Notification No. 1231. As is clear from Table 1, the structure of this comparative example is better than the structure using isocyanurate foam or phenol foam in terms of external shape after combustion, smoke emission coefficient, and exhaust temperature after 5 minutes. Although it has improved, its liquidity has been poor. Comparative example 2 Heteroform 28264 (manufactured by Futsker, trade name)

To a solution containing 1.42 parts by weight of Freon 11 (manufactured by Sun Abot Co., Ltd., trade name) and 25 parts by weight of Freon 11 (manufactured by Mitsui Fluorochemical Co., Ltd., trade name), 101 parts by weight of Isonate 580 (manufactured by Abbot Co., Ltd., trade name) was added. Stir and mix for 5 seconds at 2000 rpm with the attached stirrer, and use the same procedure as in Reference Example 1 to obtain a structure in which the isocyanurate foam (thickness 15 mm) has a colored iron plate on the surface and aluminum kraft paper on the back. Ta. In this case, the panel filling property of the foam was 4 to 5 points, the foaming height was 290 mm, the wedge-shaped flow distance was 210 mm, the density of the foam was 0.035 g/cm 3 , and the water absorption at the edges was 40 g/m. Also, using this structure, Ministry of Construction Notification No. 1231
Table 1 shows the results of the quasi-nonflammability test based on No. As is clear from Table 1, the water absorption amount of the structure of this comparative example was superior to that of the foam of the reference example, but the change in appearance after combustion was significant and most of the foam was burned out. It was also significantly inferior in terms of smoke generation coefficient and time-temperature area. Comparative example 3 Danphenon 110A (manufactured by Hodogaya Chemical Co., Ltd., trade name)
Add 40 parts of Danphenone 110B curing agent (manufactured by Hodogaya Chemical Co., Ltd., trade name) to a solution of 100 parts by weight and 15 parts by weight of Freon 11 (manufactured by Mitsui Fluorochemical Co., Ltd., trade name).
A solution containing 15 parts by weight of Danphenon 110C foam stabilizer (manufactured by Hodogaya Chemical Co., Ltd., trade name) was added, and the mixture was stirred for 5 seconds at 2000 rpm with a stirrer equipped with turbine blades. Reference Example 1 is shown below. In the same manner as above, a structure was obtained in which a colored iron plate was adhered to the surface of a phenol foam (thickness 15 mm) and aluminum kraft paper was adhered to the back surface.
However, since the phenol foam has significantly poor curing properties, after-curing was performed at 100°C for 30 minutes. In this case, the panel filling property of the foam was 2 points, the foaming height was 230 mm, the wedge-shaped flow distance was 100 mm, the density of the foam was 0.040 g/cm 3 , and the water absorption at the edges was 210 g/m. Since flyability occurred on the surface of the phenol foam, the adhesion between the foam and the aluminum kraft paper and the colored iron plate was poor. Table 1 shows the results of semi-flammability tests conducted on this structure based on Ministry of Construction Notification No. 1231. As is clear from Table 1, the structure of this comparative example had a good appearance after combustion, but the afterflame was long and inferior.
