Title: Improvements in or relating to priming or surfacing absorbent foundations
IPC: B27K3/50
Filed: 1930-08-27
Abstract: Compositions for priming or surfacing absorbent foundations such as wood, natural or artificial stones, textiles, felt, &c., comprise aqueous emulsions of condensation products prepared from polyvalent alcohols, polybasic acids and monobasic carboxylic acids containing several unsaturated linkages.  Known emulsifying agents such as salts of sulphonic or carboxylic acids of high molecular weight, or albuminous substances, may be used, preferably salts of ammonium or volatile bases.  Drying agents may be added.  The use of organic solvents is avoided.  Fillers such as ground slate, ferric oxide, or talc may be incorporated, also organic dyes or inorganic pigments. In the absence of fillers, the compositions may be used for impregnating wood, stone and structural materials for protection against chemical and mechanical action, or for priming preparatory to the application of paint.  Cardboard, leather and other fibrous materials may be treated with the compositions and patterns or artificial grains impressed thereon by stamping &c.  In examples, (1) A condensation product produced from glycerine, linoleic acid and phthalic anhydride is made into a stable emulsion, with the addition of a small quantity of manganese naphthate and lead naphthate, by means of an aqueous solution of di-isopropyl-naphthalene sulphonate and the ammonium salt of a saponifiable wax.  A mixture of ferric oxide, ground slate and talc, made into a paste in water, is ground with the emulsion.  The composition may be used for coating sheets of wood fibre &c.  (2) A condensation product produced from pentaerythrite octadecadien-9.11-acid-1 obtained by the dehydration of ricinoleic acid, and maleic acid anhydride, with a siccative as before, is made into an emulsion by means of an aqueous solution of casein and ammonia, and fillers incorporated as in example (1).  (3) A soft condensation product made by heating glycerine, eleostearic acid, adipic acid, maleic acid anhydride and phthalic anhydride is emulsified, with the addition of a siccative, by means of a solution of casein and ammonia, and the emulsion worked up with fillers and water as before.  (4) A condensation product obtained by heating glycerine, linoleic acid and phthalic anhydride, with the addition of cobalt linoleate as a siccative, is emulsified by means of a solution of casein, an ammonia salt of a saponifiable wax, ammonia and borax, and the emulsion diluted to a consistency suitable for spraying. Reference has been directed by the Comptroller to Specification 349,988.ALSO:Compositions for impregnating, priming or surfacing absorbent foundations such as textiles, felt, &c. comprise aqueous emulsions of condensation products prepared from polyvalent alcohols, polybasic acids and monobasic carboxylic acids containing several unsaturated linkages.
