This invention provides a weather-resistant metal protective coating and its preparation method. The weather-resistant metal protective coating comprises a modified epoxy resin, modified carbon nanotubes, a curing agent, an initiator, and a diluent. The modified epoxy resin is prepared by reacting epoxy resin sequentially with methyldodecyl dichlorosilane and hydroxyethyl methacrylate ethyl phosphate. The modified carbon nanotubes are prepared by reacting carboxylated carbon nanotubes with 3-(methacryloyloxy)propyltrimethoxysilane. The weather-resistant metal protective coating prepared by this invention exhibits excellent anti-corrosion, anti-aging, and mechanical properties.

This invention provides a method for preparing a lithium-ion battery positive electrode slurry, belonging to the field of lithium-ion battery technology. The method includes the following steps: dissolving an auxiliary binder in a first solvent, adding a high-nickel positive electrode active material for a first mixing treatment to obtain a first mixture; adding a conductive agent to the first mixture for a second mixing treatment to obtain a second mixture; adding a main binder to the second mixture for a third mixing treatment to obtain the lithium-ion battery positive electrode slurry; wherein the auxiliary binder is a copolymer of trifluoroethyl methacrylate and 2-(methacryloyloxy)ethyl phosphate, and the main binder is a fluoropolymer binder. This invention can improve the dispersion stability and coating processing performance of the high-nickel positive electrode slurry.

This invention belongs to the field of membrane separation technology, specifically relating to an amphoteric ion-modified antifouling ultrafiltration membrane, its preparation method, and its application. The preparation method of the amphoteric ion-modified antifouling ultrafiltration membrane includes the following steps: uniformly dispersing an amphoteric polymer, a ureidopyrimidinone functional monomer containing double bonds, and dopamine hydrochloride in a solvent, adjusting the pH to obtain a modified solution; coating the modified solution onto an ultrafiltration membrane, reacting it in the dark, and performing post-treatment after the reaction to obtain the final product; the amphoteric polymer is obtained by copolymerizing 2-acrylamido-2-methylpropanesulfonic acid and a quaternary ammonium monomer; the quaternary ammonium monomer is obtained by reacting oleamide-propyl dimethyl tertiary amine and ethylene 2-(methacryloyloxy)ethyl phosphate. The amphoteric ion-modified antifouling ultrafiltration membrane provided by this invention not only has excellent antifouling properties but also good long-term stability.
