Abstract
Moulded products are prepared by mixing a considerable excess of fibrous material, (such as wood meal, sawdust, wood felt, sugar cane, wood pulp, cork meal, asbestos, leather waste, textile fibres or pulverulent material) with an aqueous hardenable artificial resin composition and working up the composition in known manner. The aqueous resin composition comprises an aqueous solution of an advanced stage phenol-aldehyde condensate that has been treated with an alkali metal hydroxide in which saponifiable fats, oils or wares or non-saponifiable fat-like substances are saponified or emulsified. The hardening of the product may be accelerated by the presence of alkali chromates, bichromate, manganese salts and metal oxides. Fireproofing agents such as phosphates, sulphates, chlorides, bromides, acetates, or water-glass may be added to the composition to increase the non-inflammability of the product. To produce loose-structure slabs the composition may be treated with an aqueous metal salt to precipitate the resin as an insoluble metal salt and the composition shaped and dried. In examples: (1) woodmeal is mixed with an aqueous solution of a sodium hydroxide derivative of a resin containing stearin or wool fat, the product is treated with ammonium phosphate solution and the composition moulded; (2) powdered asbestos is treated with an aqueous solution of a sodium hydroxide derivative of a resin containing colophony. Specifications 28155/10, [Class 2 (iii)], 398,618, [Group VIII], 413,628; 414,632, [Group VIII], 417,948, [Group III], and 425,032 are referred to.
