NOVELTY - A conductive paste preparing method involves utilizing raw material. The raw material is sintered, the mixture is poured into cold water and the resulting melt is quenched, soaked with hydrochloric acid solution to obtain glass powder. Hydroxyethyl cellulose, terpineol, ethyl acetate and isopropanol are mixed to obtain hydroxyethyl cellulose organic carrier. Material A and material B are prepared followed by mixing material A, material B, coupling agent, silicone leveling agent, stearic calcium and zinc stearate to obtain a finished product.    USE - Method for preparing conductive paste that is utilized in solar cell production.    ADVANTAGE - The conductive paste is lead-free, and has high cell photoelectric conversion efficiency and increased contact area of particles, so that conductivity of the paste is improved.    DETAILED DESCRIPTION - A conductive paste preparing method involves utilizing raw material comprising 5-8 pts. wt.tin oxide, 6-8 pts. wt. vanadium pentaoxide, 17-19 pts. wt. boron trioxide, 17-19 pts. wt. zirconium oxide, 6.8-8.5 pts. wt. silicon dioxide, 3-4 pts. wt. antimony trioxide, 2.7-5.1 pts. wt. potassium oxide, 6-8 pts. wt. arsenic trioxide, 7-9 pts. wt. sodium oxide, 1-2 pts. wt. magnesium oxide, and 2-4 pts. wt. copper oxide. The raw material is sintered at 1100-1200 degrees C for 1.5-3 hours, the mixture is poured into cold water and the resulting melt is quenched, soaked with10-12% hydrochloric acid solution for 2-4 hours, washed with deionized water until neutral, and dried to obtain 20-25 mu m glass powder. 6-8 pts. wt. bisphenol A type epoxy resin, 1-2 pts. wt. cellulose acetate butyrate, 1-2 pts. wt. polyethylene glycol, 15-20 pts. wt. propylene glycol monobutyl ether, 14-16 pts. wt. ethylene glycol ethyl ether, and 1-2 pts. wt. glycerol triacetate are mixed to obtain bisphenol A type epoxy resin of an organic carrier material. The bisphenol A type epoxy resin of organic carrier material after mixing, is stirred at 55-60 degrees C dissolved, over 300-500 mesh filter cloth to obtain the bisphenol A type epoxy resin, and organic carrier for further use. 8-10 pts. wt. hydroxyethyl cellulose, 1.5-2 pts. wt. tricresyl phosphate, 10-12 terpineol, 16-18 pts. wt. ethyl acetate, and 5-7 pts. wt. isopropanol are mixed to obtain hydroxyethyl cellulose organic carrier. Organic vehicle hydroxyethylcellulose is prepared after mixing each raw material, dissolved with stirring at 55-60 degrees C, over 300-500 mesh filter cloth. 1-5 micron silver powder, 30-35 pts. wt. 30-60 nm silver powder, 10-12 pts. wt. organic carrier, 20-25 micron glass powder, 20-23 pts. wt. bisphenol A type epoxy resin, 1-2 pts. wt. epoxidized soybean oil, 0.2-0.3 pts. wt. dimethyl carbonate are mixed to obtain a material A. Material B is prepared by mixing 1-5 microns copper powder, 20-25 mu m glass powder, 22-25 pts. wt. hydroxyethylcellulose organic carrier, and 1-2 pts. wt. castor oil, followed by mixing 76-79 pts. wt. material A, and 18-21 pts. wt. material B, 18-21 pts. wt. silane coupling agent, 2-3 pts. wt. silicone leveling agent, 0.3-0.5 pts. wt. stearic calcium, 0.7-1.2 pts. wt. zinc stearate, and 0.4-0.8 pts. wt. isononyl phthalate, ball milling, grinding till the slurry fineness having less than 10 mu mm, adjusting the viscosity to obtain a finished product.
