The invention discloses an optical coating rubbing coating as well as a preparation method and application thereof, and belongs to the technical field of coatings. The coating comprises a first treating agent layer, a colored paint coating layer, a UV primer layer, an optical coating layer, a second treating agent layer, a PU intermediate paint layer, a gold stamping layer, a third treating agent layer and a UV finish paint layer. The structure of the optical coating layer is five, and the material of the optical coating layer comprises silicon dioxide, lithium sesquioxide, silicon dioxide, lithium sesquioxide and silicon dioxide metal overlapped coating layers which are sequentially coated on the UV primer layer. The preparation method of the coating comprises the following steps: sequentially spraying the first treating agent layer, the colored paint coating layer and the UV primer layer on the surface of the base material, carrying out optical coating, continuously spraying the second treating agent layer and the PU intermediate paint layer, carrying out gold stamping treatment, continuously spraying the third treating agent layer and the UV finish paint layer. Through the synergistic effect of different components, the adhesive force of the coating is improved, and meanwhile the coating has the good metal texture and the high-texture visual effect.

This invention belongs to the technical field of aluminum powder passivating agents, specifically relating to an aluminum powder passivating agent and its preparation method. The preparation method of the aluminum powder passivating agent includes the following steps: heating a solvent, adding anchoring functional monomers, including styrene-based phosphoric acid, hydroxyethyl methacrylate phosphate, and 2-methacryloyloxyethyl phosphate, stirring until homogeneous, continuing to add mixed monomers, stirring until homogeneous, adding a mixed solution of initiator and solvent dropwise, allowing the reaction to complete, adding solvent to adjust the solid content after the reaction, cooling to room temperature, and obtaining the aluminum powder passivating agent. This invention provides a novel aluminum powder passivating agent and its preparation method. This passivating agent forms a stable protective layer through surface passivation, effectively blocking the contact between aluminum powder and water, inhibiting hydrogen generation, avoiding can bulging, and exhibiting high stability.

This invention discloses a preparation process for metallic textured colored powder coatings, comprising the following steps: Step 1, raw material weighing and addition: polyester resin, epoxy resin, and floating silver aluminum powder solid raw materials are weighed and controlled using a quantitative component, and added into a raw material premixing component; Step 2, raw material premixing: after injecting the polyester resin, epoxy resin, and floating silver aluminum powder solid raw materials into the premixing component, the solid raw materials inside are thoroughly stirred and mixed by the premixing component; Step 3, melt mixing and extrusion: subsequently, the mixture is injected into a heated mixing component through a connected pipe, and the molten coating is subjected to secondary extrusion mixing by a melt mixing component located inside the heated mixing component; the fully melt-mixed coating is then extruded and extruded out; Step 4, cooling and pressing; Step 5, pulverizing and screening. This invention ensures thorough mixing of raw materials during the melt processing.

The invention discloses a PVB (polyvinyl butyral) interlayer with a local metalized pattern, a preparation method of the PVB interlayer and application of the PVB interlayer in laminated glass. The PVB interlayer comprises a PVB base material layer and a local metalized pattern layer, the to-be-printed surface of the PVB base material layer is subjected to corona treatment or low-temperature plasma treatment, so that the surface energy of the to-be-printed surface is not lower than 42 mN / m; the local metallization pattern layer is formed by digital ink-jet printing, drying and curing of metal effect pigment printing ink on a preset area of the to-be-printed surface of the PVB base material layer; the metal effect pigment printing ink comprises a special effect metal pigment, the special effect metal pigment is a flaky pigment, the average particle size d50 of the special effect metal pigment is 0.5-5.0 [mu] m, and the maximum particle size D100 of the special effect metal pigment does not exceed 10 [mu] m. After the PVB interlayer is applied to the laminated glass, the laminated glass has aesthetic effects and functional characteristics and can be applied to the fields of buildings, automobiles, interior decoration and the like.
