The invention provides a solar cell back silver slurry which can reduce the cost, and guarantee better conductivity of a silver layer and great adhesive force with a silicon substrate, and a preparing device thereof. The solar cell back silver slurry is composed of: 65%-75% of powdery mixed materials, 8%-10% of ethyecellulose, 8%-10% of butyl carbitol, 5%-8% of terpilenol, 2%-4% of thixotropic agents and remaining weight ratio of auxiliary agents, wherein the powdery mixed materials are the mixed materials of silver-coated copper powder and glass powder, and the weight ratio between the silver-coated copper powder and the glass powder is (7-12):1. The content of pure silver in the back silver slurry is only about 35%, which is much lower than the heavy silver content of present back silver slurry, so that the usage amount of silver powder is substantially reduced, the cost of the back silver slurry is greatly reduced, and the cost pressure caused by silver cost increase can be alleviated; in addition, greater adhesive force exists between a finally prepared silver layer and the silicon substrate, and the binding property, solderability and soldering resistance are greater. The solar cell back silver slurry and the preparing device thereof are suitable for popularization in the electronic material technical field.

The present invention intends to provide a manufacturing method for a PDP that can continuously apply phosphor ink for a long time and can accurately and evenly produce phosphor layers even when the cell construction is very fine. To do so, phosphor ink is continuously expelled from a nozzle while the nozzle moves relative to channels between partition walls formed on a plate so as to scan and apply phosphor ink to the channels. While doing so the path taken by the nozzle within each channel between a pair of partition walls is adjusted based on position information for the channel. When phosphor particles is successively applied to a plurality of channels, phosphor ink is continuously expelled from the nozzle even when the nozzle is positioned away from the channels. The phosphor ink is composed of: phosphor particles that have an average particle diameter of 0.5 to 5 mum; a mixed solvent in which materials selected from a group consisting of terpineol, butyl carbitol acetate, butyl carbitol, pentandiol, and limonene are mixed; and a binder that is an ethylene group polymer or ethyl cellulose containing at least 49% of ethoxy group (-OC2H5) cellulose molecules.

The invention discloses a heat-insulating and mildew-resistant water-based paint for a glass door. The water-based paint is characterized by being prepared from the following raw materials in parts by weight: 23-26 parts of an epoxy resin emulsion, 40-45 parts of water-based amino-alkyd resin, 0.3-0.5 part of a flatting agent BYK-307, 1-2 parts of zinc powder, 0.5-1.0 part of a silane coupling agent NQ-71, 0.2-0.3 part of nanometer ground calcium carbonate, 0.2-0.4 part of a polyacrylate thickener, 0.4-0.7 part of hollow glass powder, 0.2-0.3 part of polyoxyethylene monoleate, 0.3-0.5 part of ceramic powder microsphere, 0.1-0.3 part of polymeric microspheres, 0.2-0.4 part of sodium diacetate, 2-3 parts of butyl carbitol, 0.2-0.4 part of liquid paraffin, 2-3 parts of ethylene glycol monobutyl ether, 0.1-0.3 part of fatty acid polyethylene glycol ester, 3-5 parts of a modified nanometer titanium dioxide photocatalyst, 1-2 parts of a pigment and 12-15 parts of deionized water. The added modified titanium dioxide photocatalyst has the functions of effectively purifying air, removing stink and odor, killing a plurality of bacteria and preventing mildew; a good thermal insulation effect is achieved by combined action of added hollow glass powder, ceramic powder microspheres and polymeric microspheres; the production cost of the paint is reduced; and the paint disclosed by the invention is excellent in various performances, does not contain a special odor, is safe and non-toxic, and can be widely applied to glass for home decoration.
