Abstract
Phenol compounds and fine granular silica will chemically react to produce phenol silicate compounds when heated in an aqueous solution with a suitable alkali catalyst. The phenol silicate compounds are then reacted with an aldehyde, epoxy and polyisocyanate compounds to produce resinous products.
Claims29
The process for the production of phenol silicate compounds and their resinous products by the following steps:
- (a) mixing about 1 part by weight of fine granular silica (SiO.sub.2) and 1 to 2 parts by weight of a phenol compound;
- (b) adding an alkali catalyst in an aqueous solution until the pH is 10 to 12;
- (c) heating said mixture to 70.degree. to 120.degree. C. while agitating for 30 to 120 minutes, thereby
- (d) producing a granular phenol silicate compound.

The process for the production of phenol silicate resinous products by the following steps:
- (a) adding 1 part by weight of fine granular silica to 1 to 3 parts by weight of a phenol compound, selected from the group consisting of phenol, p-cresol, o-cresol, m-cresol, cresylic acid, xylenols, resorcinol, cashew-nut shell liquids, anacordol, p-tert-butyl phenol, p-tert-amyl phenol, p-phenyl phenol, cardol, anacardic acid, Bisphenol A, creosote oil, 2,6-dimethylphenol and mixtures thereof;
- (b) adding an alkali catalyst, in an aqueous solution to the silica and phenol compound, selected from the group consisting of sodium hydroxide and potassium hydroxide until the pH is 10 to 12;
- (c) adding an aldehyde to said mixture in the ratio of 0.5 to 3 mols to each mol of the phenol compound, and the aldehyde is selected from the group consisting of formaldehyde in an aqueous solution, acetaldehyde, butylaldehyde, acrolein, paraformaldehyde, furfural, crotonaldehyde and mixtures thereof;
- (d) heating said mixture to 70.degree. to 120.degree. C. for 30 to 120 minutes while agitating, thereby
- (e) producing a poly(aldehyde phenol silicate) resinous product.
