The paint spraying material provided by the invention comprises 0.4-0.7% of a Levelol835 acrylate leveling agent. The invention adopts the combined action of the leveling agent and other raw materials, so that the paint spraying material has better smoothness and paint fastness.
The paint spraying material provided by the invention comprises 3-6% of colorless transparent anti-counterfeiting fluorescent powder. The colorless transparent anti-counterfeiting fluorescent powder is mainly prepared from rare earth. The colorless transparent anti-counterfeiting fluorescent powder is purchased from Guangzhou Mingbo anti-counterfeiting technology Limited.
The paint spraying material provided by the invention preferably further comprises color concentrates, and the color concentrates are selected from one or more of red, yellow and blue. The prepared button realizes a transparent effect without adding color concentrate, and instantly changes color under fluorescence and does not change color under natural light. If a semi-transparent product and a colored product are realized, various color concentrates and color paste pigments are added into the main material for color matching, the specific addition amount is preferably 0.1-10%, and the mixture can be sprayed on the surface of the button to achieve the required effect after being uniformly stirred.
