Problems solved by technology

Due to the use of inorganic particles, the system has dispersion stability problems
In addition, the performance of the coating composition does not reflect the elastic self-healing performance and the scratch resistance of sharp objects except for the abrasion resistance of the paper tape.
Moreover, the composition contains an organic solvent, which has the disadvantages of environmental protection, production safety, complicated process and high cost.
In addition, the paint is also only suitable for ordinary occasions, and it is not mentioned that it is suitable for brightness-enhancing film paint

Abstract

The invention relates to an ultraviolet light curing elastic self-healing coating composition. The composition comprises the following components in parts by weight: 10-70 parts of elastic light-cured resins, 10-70 parts of light curing monomers, 1-5 parts of light initiators and 0.05-1 part of auxiliary, wherein the elastic light-cured resins are tri-functional acrylate unsaturated polymers having a soft-hard segment structure and high elasticity performance. The ultraviolet light curing elastic self-healing coating composition can be coated on a PET substrate, and the coating subjected to ultraviolet curing is high in elastic self-healing performance, extremely high in adhesion force, abrasion resistance and scratching resistance.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet light curing coatings, and in particular relates to an ultraviolet light curing elastic self-repairing coating composition. Background technique [0002] As an important accessory and brightness source of LCD display, backlight module plays a very important role in the brightness of LCD display. People try various ways to improve LCD display brightness from the aspect of backlight module. Adding a brightness enhancing film between the light guide plate and the lower polarizer is one of the methods. [0003] Through the molding process, the special prismatic structure on the mold is transferred to the substrate to obtain a brightness enhancing film. Among them, the performance of the brightness enhancement film coating can determine the quality of the brightness enhancement film performance, which is the key to the production of the brightness enhancement film. In the assembly line productio...
