Problems solved by technology

Inorganic fluorescent compounds have high luminous efficiency and good thermal stability, but their sources are limited and their dispersion in organic polymers is poor, their mechanical stability is relatively poor, it is difficult to process and shape, and the fluorescent powder is easy to fall off
Although organic fluorescent powders have strong fluorescent properties in the solution state, their fluorescence properties drop sharply or even disappear in the solid state, which is the so-called aggregation-induced quenching phenomenon, which limits the preparation and application of fluorescent paints.

Abstract

The invention discloses a nanometer silicon dioxide-acrylic acid composite fluorescent resin and a preparation method thereof. The nanometer silicon dioxide-acrylic acid composite fluorescent resin is prepared from the following raw materials of 0.1 to 3wt% of fluorescent nanometer silicon dioxide, 35 to 65wt% of acrylate monomer mixture, 30 to 60wt% of mixed organic solvent, 0.5 to 5wt% of initiator, and 1 to 3wt% of chain transfer agent, wherein the fluorescent nanometer silicon dioxide is chemically modified by tetraphenyl ethylene derivatives. The prepared nanometer silicon dioxide-acrylic acid composite fluorescent resin has the advantages that the fluorescent property is stronger, the easiness in aggregation-induced quenching effect of the traditional florescent light emitting material is overcome, and the coating after curing of composite resin has uniform mechanics and fluorescent light emitting properties.

Description

technical field [0001] The invention belongs to the field of fluorescent composite materials, in particular to a nanometer silicon dioxide-acrylic acid composite fluorescent 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 color is particularly bright and the color purity is high. The so-called fluorescence refers to a kind of cold luminescence phenomenon of photoluminescence. When a substance at room temperature is irradiated by incident light of a certain wavelength (usually ultraviolet or X-ray), it absorbs light energy and enters an excited state, and immediately de-excites and emits outgoing light with a wavelength longer than that of the incident light (usually at a wavelength of Visible light band); and once the incident light is stopped, the luminescent phenomenon will disappear immedia...
