IPC: C09D5/02
Filed: 1953-11-16
Abstract: In a modification of the emulsion coating composition of the parent Specification (A) the rheological system formed by the solids and water in the coating composition is responsible for the specified viscosity characteristics and the solids in the system other than monovalent anionic soaps and proteinaceous solids are regarded as inert solids, (B) the proteinaceous solids have a soya protein equivalent volume of 1 to 13 per cent of the volume of inert solids, (C) the monovalent anionic soaps have total volume of 0.5 to 7 per cent of the volume of inert solids, (D) the sum of soya protein equivalent volume of the proteinaceous solids and total volume of soap is between 1.5 and 14 per cent of the volume of inert solids, (E) the soya protein equivalent volume of the proteinaceous solids to the total volume of monovalent anionic soaps is between (a) 1 : 3 and 9 : 1 when the sum of the soya protein equivalent volume of the proteinaceous solids and the total volume of monovalent soaps is less than 5 per cent of the volume of the inert solids and (b) 1 : 1 and 13 : 1 when it is between 5 and 14 per cent of the volume of the inert solids, (F) the water content is between 40 and 60 per cent of the total weight of the composition, and (G) any pigment is present in flaked and/or unflaked form.  Additional ingredients mentioned are film-forming polymers of isoprene and acrylates, and copolymers of vinyl chloride and vinyl acetate, butadiene and acrylonitrile, vinyl chloride and vinylidene chloride, methyl acrylate and ethyl methacrylate and acrylonitrile and isobutylene; waxes, pigments, asbestine and coating clays, and emulsifying amine soaps, e.g. of morpholine and 2-amino-2-methyl-1-propanol.  Examples describe (1) a clear composition of butadiene - styrene latex, monoethanolamine laurate, soya protein solution, pine oil, monoethanolamine phosphate and cobalt driers; (2) as (1) pigmented with mica, titanium dioxide and lithopone; (3) an emulsion polymerized chloro - 2 - butadiene - 1,3, with zinc oxide and mica and the emulsifiers of (1); (4) as (3) but with an acrylontrile-isobutylene latex; and (5) a clear composition as (1) but with casein protein.ALSO:In a modification of the emulsion coating composition of the parent Specification (A) the rheological system formed by the solids and water in the coating composition is responsible for the specified viscosity characteristics and the solids in the system other than monovalent anionic soaps and proteinaceous solids are regarded as inert solids (B) the proteinaceous solids have a soya protein equivalent volume of 1 to 13 per cent of the volume of the inert solids (C) the monovalent anionic soaps have a total volume of 0.5 to 7 per cent of the volume of inert solids (D) the sum of soya protein equivalent volume of the proteinaceous solids and total volume of the soap is between 1.5 and 14 per cent of the volume of inert solids (E) the soya protein equivalent volume of the proteinaceous solids to the total volume of monovalent anionic soaps is between (a) 1:3 and 9:1 when the sum of the soya protein equivalent volume of the proteinaceous solids and the total volume of monovalent soaps is less than 5 per cent of the volume of the inert solids and (b) 1:1 and 13:1 when it is between 5 per cent and 14 per cent of the volume of the inert solids, (F) the water content is between 40 and 60 per cent of the total weight of the composition and (G) any pigment is present in flaked and/or unflaked form.  Additional ingredients also mentioned are, film-forming resins; polymers of isoprene and acrylates, and copolymers of vinyl chloride-acetate, butadieneacrylonitrile, vinyl chloride-vinylidene chloride, methyl acrylate-ethyl methacrylate, and acrylonitrile-isobutylene; waxes; pigments, asbestine and coating clays; and emulsifying soaps of amines, e.g. morpholine and 2-amino-2-methyl-1-propanol.  Examples describe (1) a clear composition of butadiene-styrene latex, monoethanolamine laurate, soya protein solution, pine oil, monoethanolamine phosphate and cobalt driers (2); as (1) pigmented with mica, titanium dionide and lithopone, (3) an emulsion polymerized chloro-2-butadiene-1, 3, with zinc oxide and mica and the emulsifiers of (1), (4) as (3) but using an acrylonitrile-isobutylene latex and (5) a clear composition as (1) but with casein protein.
