preparation example Construction

[0051] The present invention also provides a preparation method of the photoluminescent coating, the method comprising the steps of:

[0052] S1. Put natural muscovite powder into a mixer, then add dispersant, film-forming aid, thickener and defoamer in sequence, and mix to obtain the first mixture;

[0053] S2. Add a photoluminescent material to the first mixture obtained in step S1 and mix to obtain a second mixture;

[0054] S3. Add polymer emulsion and deionized water to the second mixture to disperse evenly to obtain a photoluminescent coating.

[0055] In the preparation method of the photoluminescent paint provided by the present invention, the photoluminescent material can be photoluminescent paint of various colors. Red photoluminescent materials, green photoluminescent materials and blue photoluminescent materials are preferred in the present invention.

[0056] Preferably, the preparation method of the red photoluminescent material is: Al 2 o 3 , MS, M'CO 3 、Eu...

Embodiment 1

[0071] 1. Preparation of red luminescent materials,

[0072] Raw material: Al 2 o 3 204g, MgS84g, CaCO 3 175 grams, Eu 2 o 3 1.76 g, La 2 o 3 3.26 grams.

[0073] The above raw materials are mixed and ground to make the particle size of the mixed powder less than 10 μm, and the microwave frequency is selected as 150 GHz. The above raw materials are fully mixed with a high-speed dispersing mixer, put into a crucible, placed in a microwave oven, heated for 40 minutes, taken out and cooled to obtain a red photoluminescent material.

[0074] 2. Preparation of photoluminescent coating:

Abstract

The present invention provides a photoluminescent coating material, which comprises 12-35% of a photoluminescent material, 1-8% of natural muscovite powder, 2-6% of a dispersing agent, 1-3% of a film forming aid, 1-2% of a thickener, 0.5-2% of an antifoaming agent, 12-20% of a polymer emulsion, and the balance of deionized water. The present invention further provides a preparation method of the photoluminescent coating material. The photoluminescent coating material of the present invention has characteristics of stable performance and storage resistance of the coated product, good decoration effect, good luminescence luminosity, and high luminescence brightness, wherein the luminescence can last for more than 10 h after the photoluminescent coating material absorbs light for 1 h.

Description

technical field [0001] The invention belongs to the field of new materials, and in particular relates to a photoluminescent coating and a preparation method thereof. Background technique [0002] Luminescent material refers to a substance that can emit light under the action of various types of energy excitation. It is widely used in various indicating products to make the product glow in the dark. With the development and progress of material science, the types of luminescent materials are also varied, and their applications are gradually diversified. From the initial indication function, applications such as instantaneous luminescence, permanent luminescence and coating decoration are extended. [0003] Photoluminescent materials refer to the luminescent phenomenon produced by exciting luminescent materials with ultraviolet light, visible light or infrared light. They are widely used in clocks, ships, aircraft dashboards, road lighting and building signs. Photoluminescent...
