Preparation method for architectural glass heat insulation coating
InactiveCN105131743AGood weather resistanceGood chemical resistanceHyaluronic acid coatingsChitin coatingsArchitectural glassAntioxidant
The invention provides a preparation method for an architectural glass heat insulation coating. The preparation method includes the steps that ATO nanometer powder, lecithin, triethoxy-1H,1H,2H,2H-tridecafluoro-n-octylsilane and dioctyl sodium sulfosuccinate are added into deionized water and stirred, then silicon carbide whiskers are added, a sodium hydroxide solution with the mass concentration of 1% is dripped on the stirring condition, stirring continues to be carried out until no precipitation is generated, and precipitation is filtered, washed with deionized water and dried to obtain heat insulation powder; the heat insulation powder, SiO2 particles and a silane coupling agent KH-570 are mixed, and the mixture is ground on a ball grinder to obtain functional powder; the functional powder, polytetrafluoroethylene wax powder, perchlorovinyl resin, zinc phosphate, polyacrylamide, mannitol, chitosan, an uvioresistant agent and an antioxidant are mixed and stirred to obtain the architectural glass heat insulation coating. The coating has excellent weather resistance, chemical resistance, waterproof performance and hardness performance.

Electroplating method of metal piece
The invention discloses an electroplating method of a metal piece. The electroplating method comprises steps as follows: a, film pasting: the to-be-electroplated metal piece is covered with an anti-electroplating film coinciding with the part which does not need electroplating; b, electroplating: the metal piece covered with the anti-electroplating film is electroplated with copper, nickel and zinc respectively, wherein an electroplating solution for zinc electroplating comprises 60-90 mg / L of benzyl pyridinium sodium carboxylate, 15-30 mg / L of triethanolamine, 50-130 mg / L of alkalized tetra-isopropylamine, 10-15 mg / L of zinc sulfate, 40-59 mg / L of sodium citrate, 25-39 mg / L of phosphorous acid, 40-55 mg / L of dioctyl sodium sulfosuccinate and 25-67 mg / L of antimony potassium tartrate, and meanwhile, electroplating parameters are limited; c, film removal: the anti-electroplating film on the metal piece is removed after electroplating. According to the electroplating method, the electroplating cost is reduced, and the phenomenon of hydrogen embrittlement is reduced.
