Abstract

The invention relates to a rare-earth modified aqueous alkyd resin antibacterial luminescent coating material. The rare-earth modified aqueous alkyd resin antibacterial luminescent coating material isprepared from the ingredients in parts by weight: 35.0-55.0 parts of rare-earth modified aqueous alkyd resin, 15.0-25.0 parts of fluorine modified aqueous alkyd resin, 0.0-25.0 parts of fillers, 1.2-6.0 parts of auxiliaries, 2.5-6.5 parts of solid glass micro-beads, 3.5-6.5 parts of film forming assistant and 10.0-30.0 parts of deionized water, wherein the rare-earth modified aqueous alkyd resinis mainly prepared from vegetable oil, an organic acid anhydride, a carboxylic acid Schiff base, polyol, benzoic acid, bis(hydroxymethyl)propionic acid, a rare-earth ethanol solution, a sodium ethoxide ethanol solution and a neutralizer through a reaction. The rare-earth modified aqueous alkyd resin antibacterial luminescent coating material disclosed by the invention has no need of adding luminescent powder and an antibacterial agent and has the characteristics of good aging resistance, difficulty in powdering, durable antibacterial performance, long luminescence duration and the like.

Description

technical field [0001] The invention relates to the preparation of a water-based paint, in particular to a rare-earth modified water-based alkyd resin antibacterial luminous paint and a preparation method thereof, belonging to the technical field of water-based functional paints. Background technique [0002] With the rapid development of my country's economy, coatings have been more and more widely used in industry and agriculture, national defense, scientific research and people's lives. Coatings are a kind of coating that is coated on the surface of objects and forms a film under certain conditions to protect and decorate. It is a kind of liquid or fixed material with specific functions. At present, there are some shortcomings in coatings, such as the surface of the decorated object is dull and unchanged, and the luminous effect cannot be displayed at night. Some raw materials are toxic or flammable and explosive, and have no environmental protection performance. Production...
