Abstract

The invention relates to a nano fluorescent invisible anti-counterfeit polyester film with high permeability and a preparation method thereof. The nano fluorescent invisible anti-counterfeit polyester film with high permeability provided by the invention comprises three layers of structure, wherein the structure is an ABA mode; the A layer material comprises a super bright polyester chip which is 68-88% of the total mass percentage of the A layer material, nano silicon dioxide composite master chip which is 10-30% of the total mass percentage of the A layer material and nano fluorescent invisible anti-counterfeit polyester functional master batches which is 1-2% of the total mass percentage of the A layer material; the B layer material is the super bright polyester chip; when the film is prepared, the nano silicon dioxide composite master chip and the nano fluorescent invisible anti-counterfeit polyester functional master batches are firstly prepared; and finally, the nano fluorescent invisible anti-counterfeit polyester film with high permeability is prepared from the nano silicon dioxide composite master chip, the super bright polyester chip and the nano fluorescent invisible anti-counterfeit polyester functional master batches. The prepared nano fluorescent invisible anti-counterfeit polyester film with high permeability has the advantages of strong tensile strength, low surface roughness and good optical effect and has the invisible anti-counterfeit function.

Description

technical field [0001] The invention relates to a polyester film and a preparation method thereof, in particular to a nano high-transparency fluorescent invisible anti-counterfeiting polyester film and a preparation method thereof. Background technique [0002] Existing biaxially oriented polyester films are widely used in flexible packaging, electronics, card protection, insulation and other fields due to their excellent physical properties and barrier properties. With the rapid development of the packaging industry and the continuous enhancement of people's legal concept and self-protection awareness, the requirements for packaging materials are getting higher and higher, and ordinary film materials can no longer meet the growing needs of special anti-counterfeiting fields. Therefore, endowing biaxially oriented polyester films with high tensile strength, low surface roughness, good optical effects, and invisible anti-counterfeiting effects through appropriate methods is o...
