preparation example Construction

[0077] The preparation method of water-based acrylic acid energy storage luminous paint, comprises the following steps:

[0078] Mix water, dispersant, wetting agent and luminescent powder pretreatment agent, stir evenly, add rare earth doped aluminate type long-lasting luminous powder and disperse at high speed, grind to obtain color paste; then add thickener to the color paste agent, stirred evenly and then filtered to obtain the finished product.

[0079] Wherein, grinding is carried out using a grinder.

[0080] The construction technology and detection method of the water-based luminous paint involved in the present invention are as follows:

[0081] The luminous paint can be applied by brushing or spraying, stir well before use, and adjust the viscosity with water. Only when the paint film thickness reaches more than 100μm and the film thickness is relatively uniform can a paint film with higher brightness be formed, for this reason, it generally needs to be sprayed 2-...

Abstract

The invention relates to the field of coatings, in particular to a water-based acrylic acid energy-storage luminescent coating and a preparation method thereof. The water-based acrylic energy-storageluminescent coating comprises the following components, by weight, 20 to 30 parts of water, 0.1 to 0.3 part of dispersing agent, 0.1 to 0.3 part of a wetting agent, 0.01 to 0.1 part of an antifoamingagent, 10 to 30 parts of rare earth doped aluminate type long-acting luminescent powder, 5 to 10 parts of a luminescent powder pretreatment agent, 30 to 50 parts of an acrylic emulsion, 0 to 20 partsof a filling material, 0.2 to 0.5 part of a thickening agent A and 0.2 to 0.5 part of a thickening agent B. According to the invention, the water-based acrylic acid energy-storage luminescent coatingis prepared by limiting the compatibility of the water-based acrylic energy-storage luminescent coating, so that the hydrolysis stability of luminescent powder is improved, and the obtained water-based acrylic energy-storage luminescent coating is low in VOC content, non-flammable, safe and convenient to construct, high in paint film adhesion, good in weather resistance and high in luminescent intensity, and the afterglow time reaches 12 h or longer.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based acrylic energy storage luminous coating and a preparation method thereof. Background technique [0002] Traditional luminescent coatings are mostly formulated with ZnS:Cu luminescent powder as the luminescent material. The afterglow of this luminescent material can only reach 1-2h, and it is easy to deteriorate and lose effect after being irradiated by ultraviolet rays or contacting oxygen. Existing paints sometimes have deuterium and Pm added to extend the afterglow 147 And other radioactive elements, but radioactive elements are harmful to the human body, so this kind of luminescent paint has been gradually eliminated by the market. [0003] In recent years, rare earth metal doped alkaline earth metal aluminates (such as SrMgAl 2 o 4 Eu +2 Dy 3+ ) type luminescent material, the afterglow time can reach more than 12h, and it has good heat resistance and anti-oxidation ...
