VACUUM INSULATION MATERIAL INCLUDING A COMPOUND GETTER AGENT

摘要

The present invention relates to a vacuum insulation material using a getter agent obtained by mixing zeolite and calcium oxide, and more particularly, to a vacuum insulation material in which zeolite having a large specific surface area to absorb the greater part of residual water in the vacuum insulation material is mixed with calcium oxide and used as a getter agent, thereby achieving improved initial heat conductivity.
