Abstract
PURPOSE: To improve heat resistance and gas shielding performance of the moisture permeable gas shield by impregnating a fibroid porous member with chemiclas including surface finishing agent.
CONSTITUTION: As the fibroid porous member, that for which white carbon and cellulose fiber are mixed at 40wt% or below is used. For example, the fibroid porous member is impregnated with chemicals adjusted by adding colloidal alumina 0.01W0.1μm in particle size at 0.5W2wt% in solid component as a surface finishing agent in an aqueous solution of moisture absorbent at 1W5wt% and water soluble high molecular compound at 5W20wt%, as stirring so as not to allow it to precipitate, and further by adding a flame retardant thereto. According to this constitution, fire resistance and gas shielding performance can be improved.
