This invention relates to the field of coatings, specifically to an industrial anti-corrosion coating and its preparation method. The coating comprises a film-forming resin, a curing agent, a solvent, and an anti-corrosion composite nanofiller. The anti-corrosion composite nanofiller has a three-layer structure: a core layer of mesoporous silica loaded with an organic corrosion inhibitor; a middle shell layer of in-situ grown amino-functionalized metal-organic framework material; and an outer layer of low surface energy formed by modification with a hydrophobic modifier.

This invention provides a sulfide electrolyte for low-temperature all-solid-state sodium-sulfur batteries and its preparation method. The sulfide electrolyte comprises a sulfide electrolyte Na3PS4 and a solid electrolyte interfacial film forming agent CuF2-NaNO3, with the CuF2-NaNO3 distributed on the surface of the Na3PS4 particles. The preparation method specifically includes: S1, preparation of the solid electrolyte Na3PS4; S2, preparation of the Na3PS4-CuF2-NaNO3 composite electrolyte. This low-temperature all-solid-state sodium-sulfur battery sulfide electrolyte and its preparation method can solve the problems of instability of sulfide electrolytes to metal anodes and sodium dendrite growth, without reducing the ionic conductivity of the electrolyte. Furthermore, this electrolyte has a self-healing function.

The invention discloses a water-based heavy anti-corrosion coating for construction with rust and residual paint films. The coating comprises an ionic water-based modified alkyd emulsion, water-based fluorocarbon resin, deionized water, an anti-rust pigment, a filler, an anti-flash rust agent, a salt spray resistant auxiliary agent, a self-repairing auxiliary agent, a penetrant, a corrosion inhibitor, a thixotropic agent and an auxiliary agent. The coating contains the anti-rust pigment, the filler, the flash-rust inhibitor and the salt-spray-resistant additive, the four components interact with each other and can act on the steel surface and rust left on the surface to generate a stable chelate passivation layer and a complex, and the product is strongly attached to the steel surface in the form of physical bonds and chemical bonds to form a good insoluble protective film, so that the corrosion resistance of the coating is improved, and the service life of the coating is prolonged. The rust inhibitor can stabilize rust and prevent rust, inhibits the corrosion process, realizes construction with rust, and has the advantages of safety, environmental protection, construction with rust and residual paint film and the like.

The invention discloses a preparation method of an optical brightness enhancement film with heat-resistant and anti-aging functions. The preparation method comprises the following steps: S1, preparing a base material film; s2, arranging a hollow glass microsphere composite heat insulation layer on the surface of the base material film: heating bisphenol A type epoxy resin to be softened, then adding hollow glass microspheres while stirring until the hollow glass microspheres are uniformly mixed, finally treating in ultrasonic waves to remove bubbles generated in the stirring process so as to obtain an intermediate coating, uniformly coating the surface of the base material film with the intermediate coating, and drying to obtain the hollow glass microsphere composite heat insulation layer. Baking and curing; s3, arranging a prism layer on the surface of the hollow glass microsphere composite heat insulation layer: preparing microcapsules with a capsule core as a healing agent, dispersing the microcapsules into a reactive diluent according to a mass percentage of 2-5%, uniformly stirring, transferring the microcapsules into an acrylic resin system, and uniformly stirring to obtain microencapsulated healing agent resin; the microencapsulated healing agent resin is coated on the surface of the hollow glass microsphere composite heat insulation layer, and then a prism layer is formed after hard roller engraving and transcription.
