ALKYD LACQUER Russian patent published in 1995 - IPC

FIELD: production of water dispersed dyes. SUBSTANCE: alkyd lacquer contains (%): alkyd resin 15-45, alkyd emulsifier 5-35, siccative 1-7, neutralizing agent 0.1-1.0, organic solvent 1-15, water 35-45. Mentioned above emulsifier is product of interaction of sun flower, soya or tallow oil or fatty acids of tallow oil, glycerine or penterytritol, phthalic or maleic anhydride, polyethylene glycol and polyvinyl butyl ether; its molecular weight being 2800-3700, acid number being 15-20 mg KOH/g. Said alkyd resin, alkyd emulsifier, siccative and organic solvent are mixed at 0-60 C within 10-15 min. Thus prepared mixture is emulsified in water which contains neutralizing agent. Resistance to cold of desired lacquer at -15 C and at -40 C is 10 cycles and 3-4 cycles respectively, its impact strength being 5 N/m, elasticity is 1 mm, hardness is 0.36, temperature of emulsifying of lacquer is 10 C. Resistance of lacquer film against static action of liquid at 20± 2^°C is 48 h. EFFECT: improves quality of desired product. 2 tbl
