Abstract

The invention discloses an environment-friendly paper-based material for a radio frequency tag antenna and a manufacturing method, the paper-based material is prepared by paper adsorbing natural alcohol-soluble or ester-soluble protein, the manufacturing method of the paper-based material comprises the following steps: step 1, preparing a protein solution, and preparing protein and a solvent into the protein solution; step 2, adsorbing paper with the protein solution prepared in the step 1; and step 3, drying the paper adsorbing the protein solution in the step 2 until the solvent is evaporated and the protein is solidified or denatured. Natural protein is used during waterproof modification treatment of the paper, artificial synthetic resin is replaced, the paper is subjected to infiltration, roller coating or spraying, then a solvent is dried and evaporated to solidify the protein, the paper is waterproof after being modified and is easy to degrade in the natural environment, meanwhile, the protein can be decomposed by microorganisms, and the water resistance of the paper is improved. Even if the treated paper is eaten by animals, the paper does not harm the animals.

Description

technical field [0001] The invention belongs to the technical field of electronic RFID (radio frequency identification) tags, and in particular relates to a base material of a tag antenna. Background technique [0002] The existing mass-produced electronic tags use PET substrates. PET is almost impossible to degrade naturally in nature, and it is difficult to collect and centralize processing, causing environmental pollution. Even after entering the ocean, it is easy to be eaten by marine organisms and cause death. [0003] In order to solve the above problems, some companies try to modify the paper to make the paper waterproof and suitable for the etching process. When modifying the paper, a synthetic resin is used to coat and infiltrate the paper. After drying, a waterproof film is formed on the surface of the paper to protect the paper. Paper can withstand wet processes such as etching, deinking, washing, etc. However, the paper treated in this way has been plasticized,...
