Abstract
Process for obtaining non-corrosive phenolic foams, essentially characterized in that it consists of mixing a liquid resin of phenol-formaldehyde of the resol type, obtained by condensation of phenol and formaldehyde in basic medium, with a sulfonated novolac, obtained in turn by sulfenating a novolak of phenol-formaldehyde or by condensation of an aromatic sulfonic acid with formaldehyde; with the particularity that a foaming agent and a surfactant agent are added to said mass; the ideal proportion of the mixture being provided as follows: 10 to 60 parts by weight of sulfonated novolac; 100 parts by weight of liquid phenol-formaldehyde resin of the resol type; 2 to 10 parts by weight of foaming agent per 100 parts by weight of mixture and 0.5 to 2% by weight of surfactant; in such a way that the mixture of the mentioned components is beaten in suitable molds without external contribution of heat.
