Abstract

The invention relates to a rare earth functionalized water-based acrylic resin anti-fouling luminescent coating. The coating comprises the following components in parts by weight: 55.0 to 80.0 parts of low-surface-tension rare earth functionalized water-based acrylic resin, 0.0 to 25.0 parts of a filler, 0.2 to 0.5 part of a thickening anti-settling agent, 0.5 to 1.0 part of a silane coupling agent, 0.1 to 0.8 part of a dispersing agent, 2.5 to 6.5 parts of a film-forming auxiliary agent, 0.3 to 0.8 part of a defoaming agent, 0.3 to 0.6 part of a wetting agent, 0.3 to 0.6 part of a levelling agent and 10.0 to 30.0 parts of deionized water, wherein the low-surface-tension rare earth functionalized water-based acrylic resin is mainly prepared from an acrylic acid soft monomer, an acrylic acid hard monomer, hydroxyethyl acrylate, polyisocyanate, a fluoroalkene monomer, a hydroxyl Schiff base monomer, a rare earth solution, absolute ethyl alcohol, acrylic acid and a neutralizer through a reaction. The rare-earth functionalized water-based acrylic resin anti-fouling luminescent coating prepared by the invention does not need additionally-added luminescent powder or an anti-fouling agent, has the characteristics of difficulty in pulverization, low surface tension, strong anti-fouling capability, long luminescent duration and the like, and has wide application prospects.

Description

technical field [0001] The invention relates to the preparation of a water-based paint, in particular to a rare-earth functionalized water-based acrylic resin antifouling luminous paint and a preparation method thereof, belonging to the technical field of water-based paints. Background technique [0002] Paint is a kind of liquid or fixed material that is coated on the surface of an object and forms a thin film under certain conditions to protect, decorate and specific functions. are becoming more and more widely used. [0003] Rare earth elements have rich fluorescence characteristics due to their unique electronic structure, which determines that rare earth materials will exhibit unique properties in terms of electricity and magnetism. However, since the 4f transition of rare earth metal ions is a forbidden transition, it is found through the study of various rare earth organic complexes that the effective energy transfer to rare earth ions through organic ligands can exc...
