Abstract
Cellular synthetic resin products are made by forming a composition comprising a liquid hardenable resin, an inert volatilizable liquid, a hardening agent and a surface-active agent, foaming the composition by vaporizing the inert liquid while the resin is still liquid, and maintaining the foamed composition at hardening temperature until the resin has hardened. In a preferred form, an aqueous syrup of a hardening agent and a surface-active agent, and the mixture is poured into a preheated heat-insulated mould, the heat of reaction being sufficient for hardening and vaporizing. Resins derived from formaldehyde and phenol, metacresols unsubstituted in o- and p-positions, or resorcinol may be employed; hardening agents specified are hydrochloric acid for phenol- and urea-formaldehyde resins, and alkali hydroxides for resorcinol-formaldehyde resins. Surface-active agents specified are sulphonated castor oils, animal glue, cationic soaps, and cetyl pyridinium bromide. Bubble formation may be assisted by incorporating a finely-divided inert solid, e.g. powdered barytes or silica (diatomaceous earth), or powder prepared from silica gels. In examples, an aqueous phenolformaldehyde resin syrup is mixed with sulphonated castor oil and hydrochloric acid, with and without silica, and the mix is placed in a rubber-lined wooden mould which has been preheated to 50 DEG C.
