Abstract

The invention discloses a low-cost energy storage luminescent paint and a preparation method thereof. The low-cost energy storage luminescent paint is prepared from, by weight, 30-50 parts of silicondioxide microspheres, 2-3 parts of a coupling agent, 20-30 parts of luminous powder, 10-25 parts of polyvinyl alcohol, 15-25 parts of an acrylic acid emulsion, 10-20 parts of a styrene-acrylic emulsion, 0.5-1 part of a wetting agent, 1-5 parts of dihydroxypropane, 0.1-0.2 part of an antifoaming agent, 0.05-2 parts of a dispersing agent, 0.2-0.5 part of talcum powder, 0.1-0.5 part of a water repellent, 0.1-0.5 part of a coalescing agent, 0.1-0.5 part of a thickening agent, 0.1-0.5 part of a pH adjuster and 10-15 parts of water. The low-cost energy storage luminescent paint and the preparation method thereof have the advantages that fluorescent powder is embedded in the silicon dioxide microspheres, and the surfaces of the silicon dioxide microspheres are modified with the polyvinyl alcohol,so that not only is the luminous efficiency of the fluorescent powder improved, but also the stability of the fluorescent powder is improved, the service life and lighting time of the paint are prolonged, the environmental friendliness is achieved, the brightness of the coating is high, the persistence time is long, the adhesion and corrosion resistance are good, and the application prospects aregood.

Description

Technical field [0001] The present invention relates to the field of luminous paint, in particular to a low-cost energy storage luminous paint and a preparation method thereof. Background technique [0002] Traditional road traffic markings are highly recognizable during the day, which can meet the requirements of traffic safety. However, at night, especially in an environment with insufficient lighting conditions, the degree of recognition is greatly reduced, and even the function of controlling and guiding traffic is lost, which seriously threatens road traffic safety. In public places, when the power is cut off in an emergency, the dark environment is likely to cause safety hazards. [0003] Energy storage coatings work in the form of "light absorption-light storage-self-luminescence". By absorbing and storing the light energy of daytime natural light, motor vehicles and various lighting lights, it is used as a luminous source at night and without light, without any other Ener...
