Waterborne epoxy zinc-rich paint modified by nanometer conductive carbon material and preparation method thereof

The invention discloses a waterborne epoxy zinc-rich paint modified by a nanometer conductive carbon material and a preparation method thereof. The paint is composed of a component A and a component B, wherein the component A comprises waterborne epoxy emulsion, the nanometer conductive carbon material, zinc powder, a waterborne antifoaming agent, a waterborne wetting dispersant and the like, and the component B is modified amine curing agent emulsion. The preparation method comprises: (1) preparing a waterborne slurry of the nanometer conductive carbon material; (2) adding water, waterborne epoxy emulsion, waterborne anti-forming agent and waterborne wetting dispersant into a stirred tank, stirring with a low speed to disperse uniformly, successively adding zinc powder, an anti-settling agent, the nanometer conductive carbon material slurry and the like, dispersing with a high speed to obtain the component A of the waterborne epoxy zinc-rich paint modified by the nanometer conductive carbon material; and (3) adding the component B into the component A, stirring uniformly and sieving. By employing the waterborne epoxy zinc-rich paint of the invention, the obtained epoxy anticorrosion coating modified by the nanometer conductive carbon material has excellent corrosion resistance and impact resistance.

Front gate line electrode silver conductor slurry for environment friendly silicon solar cell

The invention relates to a formula of an environment-friendly Ag conductor slurry for a silicon solar cell front gate line electrode and a processing method thereof. The component and the content (weight percentage) of the Ag slurry are: a metal Ag powder 60-80, a lead-less glasses adhesive 1-10, an Ohm contact additive agent 0. 05-10, and organic resin 2-15and a slurry modifying agent 1-8 The production method of the environment-friendly Ag conductor slurry comprises a preparation of the lead-less glass adhesive, a formula of the Ag slurry and a processing process of the slurry. The developing Ag slurry implements the slurry lead-free by using a Ba-Zn-B glass material and the lead content of the slurry is less than 100 ppm, while the content of other harmful substances such as Hg and Cd or the like is all conformed to the environment protection demand. A good Ohm contact is formed on the silicon surface of the Ag line and the cell by adding the Ohm contact forming agent in the slurry. The Ag slurry has strong adhesive force, superior weldability, good Ohm contact and high cell conversion efficiency after a continuous tunnel furnace fast heat treatment when the Ag slurry is used in the silicon solar cell front gate line electrode.
