Abstract

A preparation method of biaxially oriented polyester (BOPET) film surface wear-resistant scratch-resistant coating relates to a preparation method of a BOPET film surface coating and solves the problems of high cost and poor wear resistance and scratch resistance of the coating when preparing the BOPET film surface wear-resistant scratch-resistant coating in the prior art. The preparation method of the invention includes the following steps of: uniformly mixing polyurethane hexa-acrylate, epoxy modified acrylate, dipentaerythritol monohydroxy hexa-acrylate, trimethylolpropane tri-acrylate, tripropylene glycol diacrylate, butyl titanate and compound cracking light trigger to obtain coating material; then coating the coating material on the BOPET film surface done with corona treatment, and finally obtaining the (BOPET) film surface wear-resistant scratch-resistant coating after ultraviolet curing. The BOPET film surface wear-resistant scratch-resistant coating has low cost and good wear resistance and scratch resistance, and the coating performance pencil hardness is over 3H.

Description

technical field

[0001] The invention relates to a method for preparing a surface coating of a biaxially stretched polyester film. Background technique

[0002] Biaxially oriented polyester (BOPET) film as a photoelectric film material has good photoelectric comprehensive properties, but due to the influence of photoelectric product application conditions, it is required to have special properties such as good wear resistance and scratch resistance. However, it is difficult for BOPET to meet the above performance requirements, so it is required to coat its surface to achieve the purpose of improving hardness and toughness, and then meet the requirements of wear resistance and scratch resistance.

[0003] At present, most of the wear-resistant and scratch-resistant coating materials on the surface of biaxially oriented polyester (BOPET) films independently developed in China are heat-cured organic silicon and nano-silica hybrid systems, and the curing time cycle Long, general...
