PHENOL RESIN FOAM BODY AND METHOD FOR PRODUCING SAME Russian patent published in 2018 - IPC C08J9/14 C08L61/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a phenol resin foam and a method for producing the foam. Foam comprises a phenol resin and a foaming agent that includes at least one compound, selected from group consisting of 1-chloro-3,3,3-trifluoropropene, 1,3,3,3-tetrafluoro-1-propene, 2,3,3,3-tetrafluoro-1-propene and 1,1,1,4,4,4-hexafluoro-2-butene. Phenol resin foam has a density of 10 kg/m³ or more and 150 kg/m³ or less, a thermal conductivity in 10 °C environment is 0.0175 W/(m×K) or less, and a thermal conductivity in 23 °C is 0.0185 W/(m×K) or less. Foam is produced by foaming and curing the foamable phenolic resin composition containing a phenolic resin, surfactant, curing catalyst and a blowing agent.

EFFECT: phenol resin foam body and a method for producing same is proposed.
