ABSTRACT:
A method for producing a phenolic molding is disclosed. The method includes the steps of mixing phenol, formaldehyde and a hydraulic cement, forming the resulting composition to a predetermined shape and maintaining the composition in the predetermined shape until an insoluble, infusible article is formed by condensation. At least 10 percent of the hydraulic cement must be Portland cement. The mole ratio of formaldehyde to phenol must be at least 1:1, and the amount of hydraulic cement must be sufficient for reaction with from 1 to 9 times the sum of the water of condensation of the phenol with the formaldehyde and the water charged to the mix. The use of reinforcing glass fibers in producing phenolic moldings is also disclosed, as well as the use of urea and resorcinol in addition to the phenol, formaldehyde and hydraulic cement.
