Noctilucent powder paint

Abstract

The invention discloses a noctilucent powder paint which is mainly prepared from the following raw materials in parts by weight: 50-90 parts of film forming agent, 10-30 parts of curing agent, 0.01-0.03 part of defoaming agent, 0.4-1.0 part of flatting agent, 0.4-1.0 part of titanium dioxide, 5-10 parts of glass beads and 8-10 parts of alkaline earth metal aluminate. In the invention, the formula of the paint is optimized, different additives are matched mutually, and the alkaline earth metal aluminate is used as the luminous material, thus the paint can emit light and reflect light at night, the luminous time is more than 12 hours, the luminous intensity can reach 1000mcd / m<2>, the paint can reflect light in the existence of weak light, and the application range of the paint can be expanded.

Description

technical field [0001] The invention relates to a luminous powder coating. Background technique [0002] As a solvent-free coating, powder coating is economical, environmentally friendly, efficient, and excellent in performance, and is welcomed by people. With the increasingly stringent requirements for environmental protection, powder coatings have developed rapidly due to their low pollution, high decorativeness, and good comprehensive performance, and are gradually replacing traditional solvent-based coatings. As the use of powder coatings becomes more and more extensive, various functional coatings appear one after another. Luminous powder coatings can be applied to parts that need to be warned at night without additional power supply. Through the characteristics of reflection or self-luminescence, it can achieve the role of night marking. . Chinese patent CN101117522A discloses a self-luminous powder coating, which uses self-luminous powder to form a self-luminous coa...

Problems solved by technology

Chinese patent CN101117522A discloses a self-luminous powder coating, which uses self-luminous powder to form a self-luminous coating. In some cases, the actual use effect cannot be achieved only by self-luminescence, which limits its scope of use.

Chinese patent CN101333357A discloses a luminous coating and its preparation method. The long-lasting luminescent powder material contains organic solvents, which have defects such as solvent pollution, low utilization rate, and short luminous time.
