| titleOfInvention | MANUFACTURING PROCEDURE FOR MOLDED PIECES IN POLYURETHANE PLASTIC FOAM, WITH NON-ALVEOLAR SURFACE LAYER. |
| abstract | A foaming liquid comprising a polyol, a gas generator, an organic polyisocyanate and/or an isocyanate-terminated pre-polymer, and such a weight of polyfunctional organic compound as to be equivalent to 7% of the weight of the polyisocyanate component, is introduced into a mould, the surface of which is at such a temperature below 100 DEG C. (preferably the range 0-70 DEG C.) that the moulded foam produced is covered by a non-cellular surface layer. The polyfunctional compound has at least two active hydrogen atoms at least one of which belongs to an amine group, but does not include primary mono-amines. It may be a polyamine, e.g. methylene-bis-ortho-chloroaniline, or an amino alcohol or amino thiol, e.g. 2-amino-2-methyl-1-propanol. Polyether or polyester polyols may be used. Suitable isocyanate ingredients are toluylene diisocyanate or hexamethylene diisocyanate. The gas generator may be water, monofluorotrichloromethane or methylene chloride. Conventional foaming and cross-linking catalysts, surface-active agents, pigments, colouring agents, antioxidants or anti-UV agents may be incorporated. The mould is preferably made of a silicone elastomer which may be contained in a cradle of steel, aluminium or plastics it may comprise merely a surface on which sheet material may be formed. |
