COMPOSITION FOR PRODUCING PHENOPLAST FOAM Russian patent published in 2013 - IPC C08L61/10 C08J9/06 

FIELD: chemistry.

SUBSTANCE: invention relates to composite high-molecular weight heat-insulation structural materials, specifically to filling-type compositions for producing composite foamed heat-insulation material and can be used in civil and industrial construction, as well as in aviation, transportation industry and mechanical engineering. The composition contains the following, pts.wt: resol type phenol-formaldehyde resin 100, foaming/curing agent 15-25, modified sorbent 5-40. The modified sorbent is natural or artificial zeolite, which is pretreated with halides of amphoteric metals selected from AlF₃ or SnCl₂ 2H₂O with content of the latter ranging from 0.01 to 20 wt % by dry mass.

EFFECT: reduced release of phenol during foaming and use of heat-insulation articles from filling phenoplast foam based on resol type phenol-formaldehyde resin and foaming/curing agent.
