Abstract
The invention discloses a resin laser display unit, a preparation method, and applications thereof, and belongs to the technical field of paint preparation. The resin laser display paint is composed of the following components in percentage by weight: 10 to 50% of modified polymethyl methacrylate, 1 to 5% of isobornyl acrylate, 1 to 5% of nitro-cotton, and 40 to 88% of butyl acetate. The modified polymethyl methacrylate (10-55%) is used to prepare the resin laser display paint, the harms to the coatings can be effectively reduced, when the coatings go through the UV offset printing; at the same time the discharge of harmful gases such as benzene, and the like, is reduced, and thus the national VOC detection standards can be met. The prepared resin laser display paint has the advantages of good stability, excellent cutting performance, and good compatibility to color powder. The preparation method is simple, the cost is low, and the method can be applied to massive production.
