The invention discloses a method for preparing a high-solid star-shaped acrylic polyurethane dispersion used for varnishes, and relates to the technical field of varnishes, using isocyanate trimer and trimethylolpropane to synthesize star cores containing NCO groups A1, star core A1 reacts with hydroxyl-terminated acrylic acid monomer to synthesize star core A2 containing double bonds, add organic solvent to star core A2 to dilute to obtain A3, then add acrylic acid monomer, functional acrylic monomer, and initiator dropwise to A3 to synthesize Star-shaped acrylic polyurethane A4, and then remove the solvent, and after neutralization, add deionized water to disperse at high speed to obtain a high-solid star-shaped acrylic polyurethane dispersion. The acrylic polyurethane dispersion prepared in the present invention can form a highly weather-resistant varnish coating film with extremely high fullness and a gloss of more than 98 by coordinating with amino resin; and the solvent content is lower than 5%, and the solid content is higher than 60%, which is environmentally friendly and pollution-free .

The invention discloses a method for preparing silver paste used for a back electrode of a photovoltaic cell. The method comprises the following steps of mixing a pasty solvent, a thickening agent and a diluting solvent, adding superfine silver powder and glass powder in the mixture, dispersing at a high speed in a sand mill, heating synchronously to evaporate the diluting solvent, thereby betterpromoting dispersion of the superfine silver at a molecular level, and finally grinding by using a three-roll grinder so as to prepare the silver paste for the back electrode of the photovoltaic cell. The silver paste used for the back electrode of the photovoltaic cell prepared by the method provided by the invention has good dispersivity, the fineness of the prepared paste material is less than8 microns, so that the method is suitable for being used in the preparation of photovoltaic cells in large scale.

The invention provides a antistatic paint for a steel structure surface and a preparation method thereof. The paint is prepared by mixing zinc-aluminum alloy powder slurry and ethyl orthosilicate slurry in a mass ratio of 3:1-5:1. The ethyl orthosilicate in the ethyl orthosilicate slurry is subjected to hydrolytic condensation under the action of a catalyst, and a furfural-furfuryl alcohol resin is added as a modifier into the zinc-aluminum alloy powder slurry. After the zinc-aluminum alloy powder slurry and ethyl orthosilicate slurry are mixed, the furfural-furfuryl alcohol resin is cured to release water molecules when meeting with acid so as to promote the further condensation of the ethyl orthosilicate hydrolytic condensation substances, and the furfural-furfuryl alcohol resin and the zinc-aluminum alloy powder react to form a interpenetrating network, thereby enhancing the crosslinking density between the paint and the steel structure substrate surface and increasing the wettability and adhesive force of the coating for the substrate.Preferably, a carbon nanotube dispersion solution and conductive mica powder can be added into the zinc-aluminum alloy powder slurry to correspondingly improve the antistatic property of the obtained coating. Therefore, the protective paint is suitable for various steel storage tank internal and external walls, large bridges, ships, offshore oil drilling platforms and other steel structure surfaces.
