Printing paint for self-luminous advertisements and preparation method thereof

Abstract

The invention discloses a printing paint for self-luminous advertisements. The printing paint comprises the following raw materials by weight: 25 parts of acrylic resin, 3 parts of rare earth luminescent powder, 10 parts of polyethylene wax, 5 parts of propyl acetate, 5 parts of epoxy resin, 2 parts of propylene glycol methyl ether acetate, 1 part of dimethyl carbonate, 2 parts of a thickening agent, 2 parts of an active diluent, 1 part of a leveling agent, 2 parts of a preservative, 20 parts of an organic solvent, an d1.5 parts of a surface hydrophobic anti-sticking assistant. According to the printing paint for self-luminous advertisements and a preparation method thereof provided by the invention, the prepared printing paint does not crack easily, has strong cracking resistance, can withstand whatever weather and the erosion of rainwater. The paint uses acrylic resin and rare earth luminescent powder as the carrier, adopts the organic solvent as the solvent, and is added with the surface hydrophobic anti-sticking assistant, and after the paint forms a film, the surface contact angle is small, and the adhesion resistance is good.

Description

technical field [0001] The invention belongs to the field of advertisement printing, and in particular relates to a printing coating for self-luminous advertisement and a preparation method thereof. Background technique [0002] Self-illuminating coatings use the principle of self-illumination. When there is light, the coating can store light for 1 hour to reach light energy saturation. When there is no light, the self-luminous coating uses the stored light energy to emit light for more than 12 hours. It has been widely used in outdoor billboards, traffic facility signs and other fields. [0003] However, the existing self-luminous coatings for the surface of billboards generally have the disadvantages of poor adhesion and weak weather resistance. Because billboards are exposed to the sun or rain for a long time, the wind and sun, and rain erosion, the coating film on the surface is easy to crack and fall off, especially at the bending part and other parts. In order to solv...

[0003] However, the existing self-luminous coatings for the surface of billboards generally have the disadvantages of poor adhesion and weak weather resistance

Because billboards are exposed to the sun or rain for a long time, the wind and sun, and rain erosion, the coating film on the surface is easy to crack and fall off, especially at the bending part and other parts. In order to solve the problem of self-luminous coating For this shortcoming, it is necessary to develop self-luminous coating products with strong adhesion and good weather resistance
