摘要:
Thermal insulation with improved thermal stability and resistance to punking. The insulation comprises a matrix of mineral fiber bound with a phenolic resin. The phenolic resin is applied to the matrix as an aqueous solution or dispersion of a resole modified with dicyandiamide or melamine, and containing an alkoxymethylaminotriazine and a proteinaceous compound.
摘要:
Aqueous phenolic resin binders emulsifiable in water containing resole modified with dicyandiamide or malamine, an alkoxymethylaminotriazine and a proteinaceous compound. The thermoset binders possess improved thermal stability and oxidation resistance. They may be used as binders of mineral fiber matrices to provide thermal insulation which is resistant to punking.

[Also in Divisions C3 and D1] A laminate may comprise a plurality of mats of silaceous inorganic material, e.g. glass cloth bound with a composition comprising a volatile liquid carrier, an inorganic binder material having a fusion point above 700‹ C. and a particle size not exceeding 10 Ám, a soluble amine-phenol-aldehyde resin and phosphoric acid or a soluble salt or ester thereof. 1-25% of binder may be used. In examples the carrier is water, the inorganic binder material is kaolin with or without hydrated alumina, the resin is a condensate of phenol, formaldehyde and dicyandiamide, the phosphorus compound is ammonium phosphate, ethyl ammonium phosphate or butyl ammonium phosphate, and the glass material is woven glass cloth. The binder also includes a quaternary ammonium silicate.
