Problems solved by technology

[0002] The existing NFC antenna ink needs to have the following major characteristics: 1. The ink smell should be low. Too high smell means that the solvent volatilizes quickly, which is not conducive to the health of the operator; 2. The NFC antenna ink is resistant to bending after forming a film on the material. Bending, that is, bending back and forth more than 10 times without breaking; 3. After soaking in acid solution, soaking in tin solution, and chemical gold test, the adhesion test results must not drop ink
There are many kinds of NFC antenna inks on the market, but most of them have the following problems. 1. The ink smell problem. Even the ink with the least smell and customer approval is toluene solvent, and too much contact with this solvent will cause have a great impact on human health
2. The problem of ink hardness. Many inks cannot take into account the various properties of the ink at the same time. Blindly increasing the crosslinking density of the ink will cause the ink layer to be too hard after the ink is filmed, and it will be brittle when bent; 3. The chemical resistance of the ink , such as acid resistance, solder resistance, chemical gold resistance and other performance requirements, similar to the second point, after these tests, the surface hardness of the ink will change to varying degrees, resulting in adhesion, bending resistance Insufficient performance such as folding

Abstract

The invention relates to printing ink for an NFC antenna. A preparation method of the printing ink comprises the following steps: firstly dissolving solid saturated polyester resin in liquid with a solvent; adding liquid unsaturated polyester resin and a dispersing agent in the solid saturated polyester resin liquid, and dispersing, so that dispersion liquid is obtained; adding carbon black to thedispersion liquid, and dispersing and uniformly stirring, so that a mixture is obtained; grinding a mixture dispersoid; taking out, adding extinction powder, PE wax liquor and polytetrafluoroethylenepowder, dispersing, and uniformly stirring; taking out, and grinding; and then adding a defoaming agent and a leveling agent, and dispersing, so that the printing ink used for the NFC antenna is obtained. The printing ink for the NFC antenna is simple in structure, harmony of all the components is good, and odor is small, thereby being more environment-friendly; and after the printing ink forms afilm, toughness of an ink layer is good, buckling performance is excellent, the system has good chemical properties, hardness of the ink layer is not obviously changed before and after test, viscosity of the printing ink is applicable to screen printing, and storability is good.
