Methods for producing phenol resin foams and foamed laminates. |
摘要 |
<p>A method for producing resol type phenol resin foams by blending two resol type phenol resins, a blowing agent and a catalyst. A low molecular weight resol type phenol resin with the number average molecular weight of less than 200 and a high molecular weight resol type phenol resin with the number average molecular weight of greater than 200 are mixed at a weight ratio of from 5/95 to 80/20 and used as the resol type phenol resin. The resol type phenol resin foams are excellent in adhesion, fire-proofness capable of foaming cure in a short time and useful for sprayed-in-place foaming, etc. The phenol resin foams produced by the invention are capable of integral foaming with rigid urethane resin foam layer into foamed laminates of excellent thermal insulation, fire-proofness, etc.</p> |
