Embodiment 1

[0032] like figure 1 , Figure 4-Figure 6 Shown, a kind of anti-counterfeiting material manufacturing method comprises the steps:

[0033] Step 1: Make the luminescent material A into the first luminescent coating, and make the luminescent material B into the second luminescent coating, and the first luminescent coating is directly attached to the second luminescent coating, so that the two luminescent coatings are back to back Fitted together to form an overall coating of luminous material. That is, one surface of the first luminescent coating and one surface of the second luminescent coating are bonded together to form a sheet-shaped luminescent material, and the first luminescent coating and the second luminescent coating are aligned along the axis of the sheet. The directions (ie, lengthwise) extend in parallel. Luminescent material A and luminescent material B are two kinds of materials with different photoluminescent properties. For example, luminescent material A is ...

Embodiment 2

[0041] refer to Figure 1-Figure 3 , Image 6 As shown, the first embodiment is to bond the luminescent material A and the luminescent material B together. The difference from the first embodiment is that in this embodiment, in step 1, the luminescent material A and the luminescent material B are respectively painted on a transparent surface. On the two opposite surfaces of the light-transmitting sheet, a first luminescent coating and a second luminescent coating are respectively formed on the two surfaces of the light-transmitting sheet. The light-transmitting sheet is preferably a transparent PET film. The PET film has good temperature resistance, high mechanical strength, is convenient for processing and setting, and is not suitable for heat deformation after setting.

[0042] When the light-transmitting sheet is a PET film, paint the luminescent material A on one surface of the PET film to form a first luminescent coating, and paint the luminescent material B on the other...

Embodiment 3

[0049] In Embodiment 1 and Embodiment 2, both luminescent material A and luminescent material B can transmit visible light. In this embodiment, at least one of the luminescent materials in luminescent material A and luminescent material B is opaque to visible light, including luminescent material A as Transmitting visible light, luminescent material B is opaque to visible light, luminescent material A is opaque to visible light, luminescent material B is transparent to visible light, both luminescent material A and luminescent material B are opaque to visible light. At this time, the first luminescent coating and the second luminescent coating composed of luminescent material A and B can only see the luminous color when the human eye is on the same side as the excitation light, that is, the human eye can see the luminescent color at a specific position. Glowing color.

[0050] Taking the luminescent material A as transparent to visible light and the luminescent material B as o...

Abstract

The invention discloses an anti-counterfeiting material and a manufacturing method. The method comprises the following steps that 1, a luminescent material A is prepared into a first luminescent coating, a luminescent material B is prepared into a second luminescent coating, and the first luminescent coating is directly attached to the second luminescent coating, so that the two luminescent coatings are attached together in a back-to-back manner to form a flaky luminescent material, the first luminescent coating and the second luminescent coating extend in parallel in the flaky axial direction, the luminescent material A and the luminescent material B are two materials with different photoluminescence characteristics, and both the luminescent material A and the luminescent material B transmit visible light and block exciting light; 2, the flaky luminescent material is cut into filaments to obtain a filamentous or strip-shaped luminescent material, and the filamentous or strip-shaped luminescent material is shaped to obtain a bent luminescent material; and 3, the bent luminescent material is cut into sections to obtain small sections of bent luminescent material, and the anti-counterfeiting material is obtained. The quality is easy to control, complicated processing equipment is not needed, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit material manufacturing, in particular to an anti-counterfeit material and a manufacturing method. Background technique [0002] Most of the existing anti-counterfeiting materials are made by positioning, that is, multiple fiber luminescent materials with luminous properties are made into a single fiber by composite spinning method, and the manufacturing cost is relatively high. In the composite spinning method, it is usually necessary to use two screw extruders to extrude the two polymers separately, and then send them to the composite spinning assembly for processing to obtain composite fibers. Many processing equipment are used, and the processing links The chain is long and the quality is not easy to grasp, which pushes up the manufacturing cost. For this reason, need a kind of anti-counterfeiting material manufacturing method that is cheaper, and manufacturing link is easy to control...
