Embodiment 1

[0094] First, as the polyol component, using the phenolic resin-based polyol A and toluenediamine-based polyol M prepared above, as shown in Table 3 below, with respect to 50 parts of the above-mentioned phenolic resin-based polyol A and 50 parts of toluenediamine Polyol-like M, mixed with 2 parts of trimethylmethoxysilane (SS2010 manufactured by Toray Dow Corning), 2 parts of silicone foam stabilizer (trade name: SH-193, manufactured by Toray Dow Corning), 3 parts of foaming catalyst (trade name: KAOLIZER No. 26, manufactured by Kao Corporation), 0.5 parts of resin catalyst (trade name: KAOLIZER No. 31, manufactured by Kao Corporation), 5 parts of water as a foaming agent source, 30 parts of flame retardant (trichloropropyl phosphate) and 1 part of foaming agent (potassium ricinoleate) to prepare polyol complex solution.

[0095] Next, using the polyol complex solution obtained above and crude MDI (trade name: Lupranate M-11S, manufactured by BASF INOAC polyurethane Co., Ltd....

Embodiment 2～3

[0099] Adjust the blending ratio of phenolic resin polyol A and toluene diamine polyol M to the ratio shown in the following Table 3, while using SN-200 0.6cst (manufactured by Toray Dow Corning Co., Ltd.) as the organosilicon compound, except Other than that, a polyol compound solution was prepared in the same manner as in Example 1. Next, using the polyol complex solution obtained above, foamable compositions for polyurethane foams were prepared in the same manner as in Example 1, respectively, to obtain slab-shaped polyurethane foams.

[0100] Then, for the polyurethane foam obtained as described above, the density, thermal conductivity, and time-dependent changes in thermal conductivity, dimensional stability, and flame retardancy were measured in the same manner as in Example 1, and the results obtained are shown in the following table. 3.

Embodiment 4

[0102] Except for using SH-200 0.6cst (manufactured by Toray Dow Corning Co., Ltd.) as the organosilicon compound, a foamable composition for polyurethane foam was prepared in the same manner as in Example 1, and then a slab-shaped polyurethane foam was obtained. In addition, the obtained polyurethane foam was measured in the same manner as in Example 1 for density, thermal conductivity, temporal change in thermal conductivity, dimensional stability, and flame retardancy. The results are shown in Table 3 below.

Abstract

Disclosed is a foamable composition for a polyurethane foam which further favorably improves the heat insulation capacity, the long-term stability and the dimensional stability of a polyurethane foam that is manufactured using carbon dioxide as a foaming agent; further disclosed is a polyurethane foam which uses said foamable composition for a polyurethane foam and achieves excellent heat insulation performance. When the polyurethane foam is manufactured using carbon dioxide for foam formation, a phenolic resin polyol obtained by adding an alkylene oxide and an aromatic amine polyol obtained by adding an alkylene oxide are used together as a polyol component, and a specific silicone compound is blended in.

Description

technical field [0001] The present invention relates to a foamable composition for polyurethane foam and a polyurethane foam, and particularly to a technique for further advantageously improving the thermal insulation performance and dimensional stability of a polyurethane foam produced by foaming with carbon dioxide. Background technique [0002] For a long time, due to its excellent heat insulation and adhesiveness, polyurethane foam has been mainly used as a heat insulation member for heat insulation of building interior and exterior wall materials and boards, heat insulation of metal siding and electric refrigerators, apartment buildings, etc. Insulation of the main body, walls, ceilings, roofs, etc. of buildings and refrigerated warehouses, and the prevention of condensation, and insulation of infusion tubes, etc. In addition, the above-mentioned polyurethane foam is usually produced by mixing a foaming agent with the polyol component, and further adding various auxilia...
