Abstract
PURPOSE: A foaming regulator is added to both the isocyanate component solution and the polyol component solution to effect foaming, thus producing rigid urethane foam of small bubble size on the average with high heat insulation performance.
CONSTITUTION: A foaming regulator such as a silicone compound having no hydroxyl, amino or other functional groups is added to the isocyanate component solution (containing usually 25W45wt% of isocyanate groups such as tolylene diisocyanate) by 0.5W5pts. In the meantime, a foaming regulator such as a silicone compound and a catalyst such as an amine are added to the polyol component solution mainly containing a polyol (usually of 300W700 hydroxyl value such as polyether polyol) by 0.5W5pts. and 0.2W3pts./100pts.wt. respectively, and further a foaming agent such as water is added. Then, they are mixed at a ratio of 1.10W0.75, preferably 0.95W0.85 NCO index to produce the objective urethane foam.
