NOVELTY - A conductive paste preparing method involves mixing glass powder raw materials in a quartz crucible uniformly to obtain mixed material. The mixed material is placed in an electric furnace to obtain melted material. The melted material is subjected to cold water quenching process to obtain quenched material. The quenched material is ball milled and sieved through different mesh sieve to obtain 1-5 mu m glass powder, 10-15 mu m glass powder and 20-25 mu m glass powder, which are soaked in acetic acid and neutralized by washing using de-ionized water to obtain a washed product.    USE - Method for preparing conductive paste for producing a solar battery.    ADVANTAGE - The method enables preparing the conductive paste with better adhesion, high photoelectric conversion efficiency, increased contact areas among particles and better conductivity.    DETAILED DESCRIPTION - A conductive paste preparing method involves mixing glass powder raw materials in a quartz crucible uniformly to obtain mixed material. The mixed material is placed in an electric furnace at 1100-1300 degrees C for 1.5-2.5 hours to obtain melted material. The melted material is subjected to cold water quenching process to obtain quenched material. The quenched material is ball milled and sieved through different mesh sieve to obtain 1-5 mu m glass powder, 10-15 mu m glass powder and 20-25 mu m glass powder, which are soaked in 7-9% acetic acid for 3-5 hours and neutralized by washing using de-ionized water to obtain a washed product. The washed product is dried to obtain glass powder with various particle diameters, followed by mixing 25-28 pts. wt. polyethylene glycol, 3-5 pts. wt. ethyl acetate, 6-9 pts. wt. terpineol and 8-10 pts. wt. t-butylphenol formaldehyde resin 204 to obtain organic carrier-A, dissolving 8-10 pts. wt. 145 rosin resin, 14-16 pts. wt. propylene glycol monobutyl ether and 20-22 pts. wt. dimethyl succinate esters by mixing to obtain organic carrier-B, mixing 10-12 pts. wt. ethyl cellulose, 27-30 pts. wt. dimethyl succinate and 3-5 pts. wt. propylene glycol monobutyl ether to obtain organic carrier-C. The 6-8 pts. wt. 1-5 mu m glass powder is added with 10-11 pts. wt. the organic carrier-A to obtain mixture-A. The mixture-A is stirred with 18-23 pts. wt. zinc powder, 48-49 pts. wt. 6-10 mu m silver powder, 15-18 pts. wt. 30-60 nm silver powder, 10-11 pts. wt. 61-90 nm silver powder and 2-3 pts. wt. silicon dioxide for 3-5 hours at interval of 20-30 minutes to obtain material-A. The 8-12 pts. wt. 20-25 mu m glass powder is added with 19-22 pts. wt. the organic carrier-B to obtain mixture-B. The mixture-B is stirred with 25-35 pts. wt. 61-90 nm aluminum powder, 30-35 pts. wt. 16-25 mu m aluminum powder and 8-10 pts. wt. 61-90 nm aluminum powder for 2-3 hours at intervals of 30-40 minutes to obtain material-B. The 3-6 pts. wt. 10-15 mu m glass powder is stirred with 19-24 pts. wt. the organic carrier-C to obtain a mixture-C. The mixture-C is stirred with 50-55 pts. wt. 6-10 mu m copper powder and 5-10 pts. wt. 30-60 nm copper powder to obtain a material-C. The 65-75 pts. wt. material-A, 15-20 pts. wt. material-B and 10-15 pts. wt. material-C is mixed with 2-3 pts. wt. silane coupling agent KH540 and 1-2 pts. wt. polyamide wax for 6-8 hours to obtain a mixed product. The mixed product is ground and sieved through 300-400 meshes sieve to obtain a finished product, where the glass powder raw materials comprises 18-21 pts. wt. silicon dioxide, 5-7 pts. wt. strontium oxide, 7.7-8.9 pts. wt. cupric oxide, 5-7 pts. wt. vanadium pentoxide, 2.5-4.1 pts. wt. calcium oxide, 9-11 pts. wt. aluminum oxide, 7-9 pts. wt. barium, 5-7 pts. wt. cerium oxide, 8-10 pts. wt. wood ash, 12-15 pts. wt. zirconium dioxide, 4-6 pts. wt. magnesium oxide and 6-8 pts. wt. lanthanum oxide.
