Problems solved by technology

[0002] The adhesion of the base film is one of the core problems of coated products. At present, the adhesion effect of the printable film is mainly achieved through the compatibility and matching of the primer coating formula and the glue formula. However, this method has a large workload and low efficiency; in addition The simple primer formula is easy to be scratched during the production process, and the surface of the film is worn, which will affect the appearance of subsequent printing
It leads to poor appearance and performance, so coating production urgently needs a way to efficiently improve adhesion and improve process yield at the same time
[0003] At present, the commonly used printing films are either only suitable for the corona formula of silica gel, or only suitable for the primer formula of silica gel, or only suitable for the acrylic adhesive system in terms of adhesion. It is difficult to achieve compatibility with different adhesive systems and different formulas.

Abstract

The invention belongs to the technical field of printing films. The invention discloses a printable hardened film formula suitable for different glue systems. The printable hardened film formula comprises the following raw materials in parts by weight: 30-80 parts of a urethane acrylate prepolymer, 5-30 parts of a diluting monomer, 0.5-10 parts of a photoinitiator, 5-30 parts of transparent nano inorganic particles, 0.05-1.5 parts of a silane coupling agent and 10-90 parts of a solvent. According to the invention, the transparent nano inorganic particles increase the surface roughness of the coating, so that the adhesion is improved, and the silane coupling agent improves the surface performance of the product and enhances the adhesion; a pressure-sensitive adhesive is bonded with the surface of a printing film through the silane coupling agent; the printable film prepared by the method is suitable for different glue systems, has good adhesion to silica gel and acrylic glue and has strong universality, and tedious formula adjustment work is omitted; and the printing film treated by the formula has the function of a hardened coating, namely scratch resistance, hardness and the like, plays a role in process protection, and can remarkably improve the yield and the production stability.
