| 摘要 |
The invention relates to a composition for a synthetic resin foam of low flammability, comprising resin component (A), hardener component (B), and filler component (C), wherein the resin component (A) contains a phenolic resin or a mixture of phenolic resin and melamine resin, the hardener component (B) contains a reaction product of an organic nitrogen base and a polyol phosphoric acid ester, and the filler component (C) contains finely ground inorganic fillers. The invention further relates to methods for producing a synthetic resin foam of low flammability, in particular for producing phenolic resin foam, melamine resin foam, urea resin foam, or mixtures thereof, comprising the following method steps: (i) dissolving the blowing agent component (D) in the mixture of resin component (A) and filler component (C), (ii) pre-foaming the mixture of resin component (A) and filler component (C) with the blowing agent component (D), and (iii) extruding and mixing the mixture of resin component (A), filler component (C), and blowing agent component (D) with the hardener component (B). |
