Abstract

PURPOSE: To maintain the proper peeling strength of a process paper as well as improve the heat resistance of the paper by a method in which a slurry composed primarily of a pigment, an adhesive, and a film-forming agent is coated on a paper base and then a liquid composed primarily of slicone is further coated on the slurry- coated paper base.
CONSTITUTION: A slurry of an approx. 30W60% concentration is prepared by mixing a pigment, an adhesive, a film-forming agent, and water. And, the slurry is coated on a paper base to a thickness corresponding to approx. 5W25g/m2 on dry base and dried, and then the paper base so treated is passed through calenders to smoothen the surface of the first coat layer. Then, a nonsolvent, organic solvent, or emulsion type of silicone or glue compound is coated on the said coat layer and then cured to form the second coat layer in order to obtain a process paper for the formation of foamed sheet. The paper base used includes kraft paper, wood free paper, etc., having a basis weight of 80W150g/m2 preferably.
