きな理由である。The main reason for this is that trichlorofluoromethane (hereinafter referred to as R-11), which has excellent filling properties and heat insulation properties, is used as a blowing agent when manufacturing the rigid urethane foam.
近年、地球のオゾン層保護のため、クロロフルオロカー

３）フライアビリティが低下し、
４）低温寸法安定性及び圧縮強さ等のフオーム物性が劣
化する。However, R-123 or R-141 as a blowing agent
When using b, compared to foaming using conventional R-11, 1) initial reactivity is delayed, 2) foaming efficiency is reduced, 3) flyability is reduced, and 4) Foam properties such as low temperature dimensional stability and compressive strength deteriorate.
等の多くの問題かあり、従来の硬質ウレタンフオームの
処方では、満足なフオームが得られない。There are many problems such as these, and it is not possible to obtain a satisfactory foam using conventional rigid urethane foam formulations.

発明に到達した。As a result of intensive studies to solve the above problems, the present inventors have found that even when R-123 or R-141b is used as a blowing agent in place of the conventionally used R-11, excellent filling can be achieved. We have found a method for manufacturing rigid urethane foam without sacrificing properties and flyability, and have arrived at the present invention.
