A heat insulating panel is used for the storage wall, and the heat insulating effect between the inside and the outside of the storage is enhanced. Conventionally, such a heat insulating panel has been prepared by injecting a foam insulating material stock solution composed of a foaming agent and a base material (for example, urethane) into a gap between facing surface materials, foaming and curing the foam insulating material stock solution. It has been manufactured by a method of filling a gap with a foamed heat insulating material having a foam structure.

ルオロカーボン)系のR−134aがある。It is known that HCFC (hydrochloroful carbon) -based foaming agent is used as a foaming agent for foaming the foamed heat insulating stock solution. However, it has already been determined that the HCFC-based blowing agent will be completely abolished, and HFC (hydrofluorocarbon) -based R-134a is a possible alternative blowing agent.

題がある。However, when HFC-based R-134a is used as a foaming agent, foaming occurs in the gap between the facing face materials as compared with the case where a conventional HCFC-based foaming agent is used. There is a problem that the time from the injection of the undiluted foam insulating material solution consisting of the agent and the base material to the completion of foaming and curing is lengthened, and the production efficiency of the insulating panel is deteriorated.

いない部分が生じるという問題がある。[0005] In addition, the foam insulating stock solution injected into the gap between the facing face materials is a liquid having a high viscosity. For example, when the thickness of the gap between the facing face materials is non-uniform, the thickness of the solution is high. Since it is difficult to inject the foam insulation stock solution in accordance with the above, there is a problem that a portion not filled with the foam insulation material occurs in the gap between the facing face materials.
