| titleOfInvention | Process for preparing pigmented acrylic dispersion lacquer coating compositions by using cellulose acetate butyrate resin |
| abstract | 1. AN IMPROVED PROCESS FOR PREPARING A PIGMENTED ACRYLIC RESIN DISPERSION LACQUER CONTING COMPOSITION WHICH COMPRISES THE FOLLOWING STEPS: (1) BLENDING TOGETHER THE FOLLOWING CONSTITUENTS TO FORM A PIGMENT/POLYMER BLEND 15-50% BY WEIGHT OF A PIGMENT; 15-35% BY WEIGHT OF CELLULOSE ACETATE BUTYRATE HAVING A BUTYRYL CONTENT OF ABOUT 30-55% BY WEIGHT AND VISCOSITY AT 25* C. OF ABOUT 0.5-5 SECONDS MEASURED ACCORDING TO ASTM D-134356; 15-55% BY WEIGHT OF A FILM-FORMING ACRYLIC RESIN; AND 0-20% BY WEIGHT OF AN ORGANIC PLASTICIZER FOR SAID ACRYLIC RESIN; (2) HEATING THE PIGMENT/POLYMER BLEND PREPARED IN STEP (1) TO ABOUT 30-110* C. WHILE MIXING AND APPLYING A VACUUM OF AT LEAST 20 INCHES OF MECURY TO FORM A POWDER; (3) MIXING THE POWDER UNDER HIGH SHEAR CONDITIONS BY CHARGING THE POWDER INTO A TWO ROLL MILL HAVING ONE HOT ROLL AT ABOUT 65-125* C. AND A COLD ROLL AT ABOUT 0-30* C. FOR ABOUT 5-40 MINUTED WHILE APPLYING 75-400 FOOT POUNDS PER GRAM OF CHARGE PER MINUTE TO FORM PIGMENT CHIPS; (4) FORMING A MILL BASE HAVING A SOLIDS CONTENT OF ABOUT 20-60% BY WEIGHT, BY DISSOLVING THECHIPS PREPARED IN STEP (3) IN AN ORGANIC SOLVENT FOR THE CHIPS; AND (5) BLENDING THE MILL BASE PREPARED IN STEP (4) WITH AN ACRYLIC RESIN DISPERSION LACQUER COATING COMPOSITION COMPRISING 10-60% BY WEIGHT OF A FILM-FORMING BINDER OF AN ACRYLIC RESIN DISPERSED IN AN ORGANIC LIQUID TO FORM A PIGMENTED COATING COMPOSITION HAVING A PIGMENT TO BINDER RATIO OF ABOUT 2:100 TO ABOUT 70:100; WHEREIN SAID ACRYLIC RESIN COMPRISES A GRAFT COPOLYMER HAVING A BACKBONE (A) AND ONE OR MORE SIDE CHAINS (B), THE BACKBONE (A) BEING A POLYMERIC SEGMENT OF UNITS (A) AND UP TO 15% BY WEIGHT OF UNITS (B), UNITS PROVIDING AVAILABLE ACTIVE GRAFTING SITES FOR GRAFT POLYMERIZATION, AND EACH SIDE CHAIN (B) ABOVE BEING A POLYMERIC SEGMETN, (A) AND (B) EACH BEING COMPOSED OF AT LEAST AND (A) AND (B) EACH BEING COMPOSED AT LEAST 50% BY WEIGHT OF UNITS OF ESTERS OF ACRYLIC, METHACRYLIC AND/OR ETHACRYLIC ACID; AND WHEREIN THE GRAFT COPOLYMER IS SELECTED FROM THE GROUP CONSISTING OF A COPOLYMER PREPARED BY POLYMERIZING METHTL METHACRYLATE/ALLYL METHACRYLATE/DIETHYLAMINO METHACRYLATE/2-ETHYL HEXYL ACRYLATE TO FORM A GRAFT COPOLYMER IN WHICH THE (A) MONOMER UNITS OF THE (A) SEGMENT CONSIST OF METHYL METHACRYLATE; AND (B) MONOMER UNITS OF (A) SEGMENT CONSIST OF ALLYL METHACRYLATE AND DIETHYLAMINOETHYL METHACRYLATE, AND THE MONOMER UNITS OF (B) SEGMENT CONSISTS OF 2-ETHYLHEXYL ACRYLATE; AND A COPOLYMER PREPARED BY POLYMERIZING METHYL METHACRYLATE/ISODECYL METHACRYLATE/METHACRYLIC ACID/ ACRYLONITRILE TO FORM GRAFT COPOLYMER IN WHICH THE (A) MONOMER UNITS OF THE (A) SEGMENT CONSIST OF METHYL METHACRYLATE, ISODECYL METHACRYLATE, METHACRYLIC ACID, AND (B) MONOMER UNITS OF THE (A) SEGMENT CONSIST OF ALLYL METHACRYLATE AND MONOMER UNITS OF THE (B) SEGMENT CONSIST OF ACRYLONITRILE. |
