Problems solved by technology

However, there are some defects in this invention: the light-absorbing performance of the luminous powder is not good, resulting in an unsatisfactory luminous effect, and the compatibility between the luminous powder and the pure acrylic emulsion matrix is ​​poor, resulting in uneven dispersion of the luminous powder in the paint. Reduced mechanical properties of coatings

Abstract

The invention provides noctilucent organic composite coating. The noctilucent organic composite coating comprises, by weight, 35-42 parts of fluororesin, 7-14 parts of acrylic resin, 5-10 parts of polyurethane resin, 0.1-0.2 part of levelling agent, 12-16 parts of diluent, 0.6-1.2 parts of dispersing agent, 8-10 parts of pigment, 10-14 parts of filler, 11-16 parts of modified noctilucent powder, 0.3-0.8 part of organic bentonite and 5-7 parts of hollow glass microspheres. The invention further provides a preparation method of the noctilucent organic composite coating. The noctilucent organic composite coating is good in noctilucent performance and mechanical performance.

Description

Technical field: [0001] The invention relates to a coating, in particular to a luminous organic composite coating and a preparation method thereof. Background technique: [0002] Luminous paint emits a certain amount of light by its own energy storage material. It absorbs light energy under the irradiation of sunlight, light, and visible light, and then emits the absorbed energy as low-frequency visible light under dark conditions. After absorbing general visible light for 10 to 20 minutes, the luminous paint can continue to glow in the dark for about 12 hours. The brightness of luminous paint can be about three times that of ordinary paint, which is unmatched by other paints. At the same time, the color is particularly bright and the color purity is high. Luminous coatings are mainly used in: [0003] 1. Architectural decoration, interior decoration, lighting, painting, wall surface; [0004] 2. Item identification marks at night, power switches, tools or toolboxes; [...
