善取組みが検討されている。For this reason, in the production of rigid urethane foam, which is a typical foam insulation material, there are methods that use carbon dioxide gas obtained by the reaction of organic polyisocyanate and water as part of the blowing agent, or alternative materials for CFC. 1,1-dichloro-1-fluoroethane (hereinafter referred to as HCFC-141b), which has little effect on ozone depletion, and 2,2

When HCFC-141b and HCFC-123 are used as blowing agents, the thermal conductivity of the rigid urethane foam is C
It is stated that the thermal conductivity is 7 to 12% worse than that of rigid urethane foam foamed with FC-11.

-141b and HCFC-123 as a blowing agent for current rigid urethane foams is extremely difficult to maintain the performance of the insulating box, and structural aspects such as increasing the thickness of the insulating walls of the insulating box are required. At present, individual efforts are being made to address these issues and develop new raw material systems.

3 has ozone depletion power of 1/10 to 1/10 compared to CFC-11.
115Q and is essential for environmental protection, but its gas thermal conductivity is said to be about 10 times higher than that of CFC-11. For this reason, it is obvious that the thermal conductivity of rigid urethane foam deteriorates when it is foamed instead of the conventional foaming formulation, and when applied to a heat-insulating box, measures such as increasing the thickness of the heat-insulating wall are necessary. The volumetric efficiency has decreased, resulting in the inability to meet market needs such as increased internal volume.

が得られるものである。Function With the above configuration, the graphite powder absorbs infrared rays in the heat transfer mechanism, and contributes to reducing the radiant heat conductivity of the urethane foam. In addition, as an effect, zeolite powder adsorbs moisture in the raw material premix, such as moisture adhering to graphite powder, and inhibits the reaction between moisture and isocyanate, thereby reducing the partial pressure of carbon dioxide in the bubbles. This makes it possible to reduce the gas thermal conductivity of the mixed gas within the cell. Therefore, even when HCFC-141b or HCFC-123, which has high gas thermal conductivity, is used as a foaming agent, an excellent foam insulation material can be obtained without deteriorating the thermal conductivity of the rigid urethane foam. be.

である。In this way, the foamed heat insulating material of the present invention uses a foaming agent with high gas thermal conductivity, HCFC-141b or HCFC-123.
It was found that even when CFC-11 was used as the foaming agent, the thermal conductivity of the resulting foamed heat insulating material was equivalent to that when CFC-11 was used as the foaming agent. This is because graphite powder absorbs infrared rays in the heat transfer mechanism.
This seems to be because it contributes to reducing the radiant heat conductivity of the urethane foam. In addition, as an effect,
Zeolite powder adsorbs moisture in the raw material premix, such as moisture adhering to graphite powder, and inhibits the reaction between moisture and isocyanate, thereby reducing the partial pressure of carbon dioxide in the bubbles and reducing the gas mixture in the cell. It reduces thermal conductivity. For this reason, HCFC-141, which has a high gas thermal conductivity,
Alternatively, even when HCFC-123 is used as a foaming agent, an excellent foamed heat insulating material can be obtained without the adverse effect of deterioration of the thermal conductivity of the rigid urethane foam.

率は大きなものとなる。In addition, in the comparative example, in the case where graphite powder and zeolite powder were not added (comparative examples A and B), HC
Because the thermal conductivity of FC-141b and HCFC-123 is high, even when compared with the CFC-11 formulation (Comparative Example C),
The thermal conductivity of the foam insulation material is high. In addition, when zeolite powder is not added, the water adhering to graphite powder reacts with isocyanate and generates carbon dioxide gas, which increases the proportion of carbon dioxide gas in the mixed gas in the cell and increases the gas thermal conductivity. Therefore, the foam thermal conductivity becomes large.

Even when No. 23 is used as a foaming agent, an excellent foamed heat insulating material can be obtained without any adverse effects such as deterioration of the thermal conductivity of the rigid urethane foam.
