Abstract

The invention discloses fluorescent epoxy resin and a preparation method thereof. The fluorescent epoxy resin comprises the following raw materials: 2,2-bisphenol-propane, (E)-4,4'-(1,2-diphenyl-1,2-diethylene) bi-benzyl bromide and epoxy chloropropane, wherein the mole ratio of (E)-4,4'-(1,2-diphenyl-1,2-diethylene) bi-benzyl bromide to epoxy chloropropane is (1:10)is similar to(1:100); the mole ratio of the sum of (E)-4,4'-(1,2-diphenyl-1,2-diethylene) bi-benzyl bromide and epoxy chloropropane to 2,2-bisphenol-propane is (2:1)is similar to(5:4). The components are directly synthesized to prepare polymer resin with a fluorescence effect, the preparation process that fluorescent powder needs to be doped in conventional fluorescent paint preparation can be reduced, the preparation process of fluorescent paint can be simplified, the defect that organic fluorescent powder doped in the conventional fluorescent paint has an aggregation induction quenching effect can be avoided, doping of the fluorescent powder is avoided, cured paint is good in mechanical property, and the phenomenon that the fluorescent powder drops off can be avoided.

Description

technical field [0001] The invention belongs to the field of fluorescent materials, in particular to a fluorescent epoxy resin and a preparation method thereof. Background technique [0002] Fluorescent paint is a kind of bright and quick-drying enamel paint, which is colored with sunlight fluorescent pigments and belongs to acrylic resin paint. The brightness can reach about three times that of ordinary paints, which is unmatched by other paints. At the same time, the color is particularly bright and the color purity is high. The wavelength range of the light emitted by the fluorescent paint is wide, and the color of the light can be changed by the type of phosphor powder added; the operation is simple, and the process can be followed. [0003] Traditional fluorescent paint achieves its luminous behavior by adding phosphor powder to the resin. General phosphors mainly include inorganic phosphors and organic phosphors. Inorganic fluorescent compounds have high luminous ef...
