Abstract

The invention belongs to the technical field of coatings, and particularly relates to a fluorescent three-proofing coating material and a preparation method thereof. The fluorescent three-proofing coating material is composed of a component A and a component B. The component A is fluorine-containing acrylic resin of a hybrid grafted fluorescent pigment, and the component B is composed of a prepolymer, a solvent and the like. The preparation method of the fluorescent three-proofing coating material comprises the following specific steps: A, preparing a double-bond-containing grafted fluorescentpigment; B, preparing the fluorine-containing acrylic resin of the hybrid grafted fluorescent pigment; C, preparing the component B; and D, preparing the fluorescent three-proofing coating material.The fluorescent pigment is grafted into the fluorine-containing acrylic resin structure, the aging resistance of a fluorescent coating layer is greatly improved in a resin coating mode, the fluorescent coating layer has good weather resistance and three-proofing performance, the problem that a traditional fluorescent coating is poor in light retention and color retention is solved, and the fluorescent coating is wide in prospect and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fluorescent three-proof coating material and a preparation method thereof. Background technique [0002] The instrument panels of automobiles, airplanes, and aviation vehicles usually have blurred or inaccurate readings at dusk or at night due to insufficient light. In serious cases, it will affect driving safety, causing casualties or property damage. Therefore, a fluorescent indicator paint has been developed, which can display fluorescent colors under a certain light source for easy identification. [0003] However, due to the inherent deficiencies in light resistance, weather resistance, and solvent resistance of fluorescent colorants, traditional fluorescent paints are prone to problems of poor color and gloss retention during long-term use. The paint prepared by using this kind of fluorescent pigment will lose light and color after being used for a certain period of ti...
