NOVELTY - A conductive silver paste comprises highly dispersed conductive silver powder, ethyl cellulose, toluene, ethanol, alkyl succinic anhydride, isooctyl acrylate, polyoxypropylene glyceryl ether, 2-methyl-1-pentanol, chitosan, lecithin, glass, nanocarbon powder, and diethyl phthalate. The highly dispersed conductive silver powder comprises nano-alumina, dioctyl sebacate, deionized water, styrene, alkyl phenol ethoxylate, silane coupling agent KH-560 (RTM: gamma -glycidoxypropyltrimethoxysilane), ammonium persulfate and silver nitrate.    USE - The conductive silver paste is useful for coating polymer microspheres.    ADVANTAGE - The conductive silver paste can be easily prepared with improved dispersibility, stability and reduced usage of noble metals in an economical manner.    DETAILED DESCRIPTION - A conductive silver paste comprises 100-106 pts. wt. highly dispersed conductive silver powder, 10-12 pts. wt. ethyl cellulose, 15-20 pts. wt. toluene, 4-6 pts. wt. ethanol, 0.1-0.2 pts. wt. alkyl succinic anhydride, 2-3 pts. wt. isooctyl acrylate, 0.2-0.3 pts. wt. polyoxypropylene glyceryl ether, 0.2-0.4 pts. wt. 2-methyl-1-pentanol, 0.7-1 pts. wt. chitosan, 0.4-1 pts. wt. lecithin, 10-15 pts. wt. glass, 2-3 pts. wt. nanocarbon powder, and 2-3 pts. wt. diethyl phthalate. The highly dispersed conductive silver powder comprises 5-10 pts. wt. nano-alumina, 0.1-0.2 pts. wt. dioctyl sebacate, 300-400 pts. wt. deionized water, 4-7 pts. wt. styrene, 0.8-1 pts. wt. alkyl phenol ethoxylate, 1-2 pts. wt. silane coupling agent KH-560 (RTM: gamma -glycidoxypropyltrimethoxysilane), 0.01-0.02 pts. wt. ammonium persulfate, 131-140 pts. wt. silver nitrate, 1-2 pts. wt. polyvinylpyrrolidone, 30-40 pts. wt. sodium hypophosphite, and 2-3 pts. wt. tris(nonylphenyl) phosphite. The highly dispersed conductive silver powder is prepared by mixing nano-alumina, dioctyl sebacate, deionized water, styrene, alkyl phenol ethoxylate, silane coupling agent KH-560 (RTM: gamma -glycidoxypropyltrimethoxysilane), ammonium persulfate, silver nitrate, polyvinylpyrrolidone, sodium hypophosphite, and tris(nonylphenyl) phosphite, stirring mixture at 500-700 rpm, ultrasonically-processing for 10-15 hours, dripping ammonia to adjust pH value of the mixture to 10-10.5, emulsifying for 30-50 minutes, centrifuging, washing with ethanol and deionized water 3-5 times, and drying. An INDEPENDENT CLAIM is included for method for preparing conductive silver paste.
