Abstract

PURPOSE: To provide a low-cost heat insulating material of high insulating effect for use in construction by a method wherein sawdust or small wood fragments immersed in a flame redarder solution and milled are mixed with a fibrous material.
CONSTITUTION: Sawdust or small wood fragments which are immersed in a flame retarder solution and milled are mixed with a fibrous material before or after the treatments, to reduce the apparent specific gravity to 0.05W0.04. The fibrous material may be ordinary fibers, recovered pulp, or used paper, and is mixed with sawdust or small wood fragments in an amount of about 1W30% of the latter.
