Patent GB-598642-A (GB)
Title: Improvements in and relating to cellular phenol-aldehyde resins
IPC: C08L61/10
Filed: 1945-10-15
Abstract: A method of producing a cellular phenolaldehyde resin comprises preparing at an initial temperature of 20-30 DEG  C. an aqueous mixture of the liquid acid-curing thermosetting reaction product of a phenol and formaldehyde or furfural, a water soluble salt of carbonic acid or nitrous acid, and a water soluble sulphonic acid having the sulphonic group attached to a hydrocarbon nucleus, which mixture thereupon expands and reacts until it solidifies as a cured cellular mass.  In an example a liquid resin ("Resin A") is prepared by boiling 1 mol of phenol and 1.3 mols of formaldehyde with a barium hydroxide catalyst, then slightly acidifying, removing any insoluble salt, and partially dehydrating the resin under reduced pressure.  In examples cellular products are obtained by mixing at 20-30 DEG  C. and allowing to react: (1) Resin A, phenol sulphonic acid, and sodium bi-carbonate; (2) Resin A, phenol sulphonic acid, sodium bi-carbonate and a surface active agent known as Tween 20; (3) Resin A, phenol sulphonic acid, sodium bi-carbonate and walnut shell flour; (4) Resin A, phenol sulphonic acid, sodium bi-carbonate, walnut shell flour, and Tween 20.  Tween 20 comprises polyethylene ethers of sorbitan mono-laurate, and its use yields cellular products of doubled volume. Suitable fillers such as walnut shell flour, diatomaceous earth, carbon black, powdered mica, or ground phenolic resin foam increase the hardness of the product.  Suitable sulphonic acids include benzene-, p-toluene-, b -naphthalene- and camphor-sulphonic acids, benzene-m-disulphonic acid, and a list is given of other suitable sulphonic acids of phenol, naphthol, and anthraquinone and their substitution products.  Suitable liquid resins set out in a list comprise products from either or both of formaldehyde and furfural, with one or more of the substances phenol, m-cresol, 3 : 5 xylenol, resorcinol, phenyl phenol, a -phenylethyl phenol, and 82 per cent phenol.  The products may be used in floats and pontoons, as thermal or sound insulation, as construction material between sheets of metal, paper or cloth, and as electrical insulation.
