Problems solved by technology

Early energy-storage luminescent paints used zinc sulfide luminescent materials as luminescent pigments, but their chemical properties were unstable, easy to decompose in the environment, and the luminescence time was short, so their applications were greatly limited.

Embodiment 1

[0053] In this example, the preparation of energy-storage-type environment-friendly luminescent paint is carried out. The energy-storage-type environment-friendly luminescent paint is composed of strontium polyaluminate luminescent material activated by rare earth ions doped with titanium dioxide and boric acid coated with silicon dioxide, film-forming substances, fillers, and auxiliary materials. The chemical formula of the rare earth ion-activated strontium polyaluminate luminescent material in the rare earth ion-activated strontium polyaluminate luminescent material of silicon dioxide-doped titanium dioxide and boric acid is 7Al 2 o 3 4SrO:Eu 2+ 0.02 :Nd 3+ 0.03 . The film-forming material is polyester imide resin (MW, 30000), the filler is nano-titanium dioxide, the film-forming aid is Loxanol CA5308, the wetting agent is Dow DOW wetting agent X-405, and the dispersant is ammonium polyacrylate Salt (MW, 2000), defoamer is emulsified methyl silicone oil (MW, 6000), ant...

Embodiment 2

[0062] This embodiment is the same as embodiment 1, the only difference is that the film-forming substance is replaced by polyurethane resin (MW, 40000).

Embodiment 3

[0064] This example is the same as Example 1, except that the film-forming substance is replaced by silicone-modified acrylic resin (MW, 6000).

Abstract

The invention belongs to the technical field of coatings, and particularly relates to an energy storage type environment-friendly luminescent coating and a preparation method thereof. The film-formingsubstance of the coating is one or more selected from polyesterimide resin, polyurethane resin, organic silicon modified acrylic resin and epoxy resin and cooperates with other components, so the energy storage type environment-friendly luminescent coating is free of caking, resistant to heat and good in insulativity, and the initial luminescent brightness and afterglow time of the rare earth ionactivated strontium polyaluminate luminescent material are guaranteed; the strontium polyaluminate luminescent material activated by rare earth ions and doped with titanium dioxide and boric acid iscoated with silicon dioxide by adopting a microemulsion method, and is cooperated with other components, so luminescent pigment particles in the obtained energy storage type environment-friendly luminescent coating are good in dispersity, the initial luminescent brightness of the rare earth ion activated strontium polyaluminate luminescent material is improved, and afterglow time is prolonged; anda toughening agent is used in the energy storage type environment-friendly luminescent coating, so the aging resistance, weather resistance and scratch resistance of the energy storage type environment-friendly luminescent coating are improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an energy storage type environment-friendly luminous coating and a preparation method thereof. Background technique [0002] Long afterglow energy storage type environmental protection luminous paint is a kind of self-luminous functional luminous paint, which has been widely used in the fields of architectural decoration, transportation, fire safety, military facilities and aviation. Early energy-storage luminescent paints used zinc sulfide luminescent materials as luminescent pigments, but their chemical properties were unstable, easy to decompose in the environment, and the luminescent time was short, which greatly restricted their applications. At present, non-toxic and non-radioactive rare earth activated alkaline earth metal aluminate luminescent materials are mainly used as luminescent pigments. It has the advantages of high luminous brightness, long afterglow ...
