Description
Technical Field
The invention relates to the field of optical functional materials, in particular to a reflective and luminous hot-pressing transfer composite film and a preparation method thereof.
Background
With the progress of seamless clothing making technology and the development of textile automation, the hot-pressing transfer material film can be directly made into functional fabrics through roller hot-pressing, flat-plate hot-ironing and high-frequency hot-pressing processes, and the process is high in convenience, so that the development demand is more and more great.
The reflective heat transfer composite film is a reflective product with a retroreflective function, is generally made by implanting transparent glass microspheres with the retroreflective function into a resin layer on the surface of the reflective heat transfer composite film, and is heated and adhered to a cloth surface and peeled off a light-transmitting carrier film when in use.
Because the reflective heat transfer composite film can only passively reflect light through a retro-reflection external light source, the use environment is limited (limited to the light environment). Therefore, a luminous hot-pressing transfer film with a long afterglow luminous function is manufactured by utilizing the energy storage and luminescence principle of the long afterglow luminous material. The luminous hot-pressing transfer film can glow after glow in dark environment, but is only suitable for fashionable, decorative, beautifying and toys due to the lack of the light reflecting function, and has limited application range.
And a long afterglow luminescent powder is added into a resin layer of the reflective thermal transfer composite film, so that the reflective luminescent thermal transfer composite film with the long afterglow luminescent function is prepared. The luminous reflective heat transfer composite film can perform afterglow luminescence in a dark environment through light storage, so that the application range (applicable to a dark environment) is expanded. However, the manufacturing of the hot-pressing transfer luminescent film has higher process requirements and difficulty than those of the fabric with the same function, while the manufacturing of the reflective luminescent hot-pressing transfer composite film has higher requirements and difficulty, the existing products mostly adopt a technical route represented by a light-storing reflective adhesive film provided by patent No. 201521009871.6, and due to process limitation, the luminescent layer is provided with glass beads, and the structure of the composite film has the following main defects:
1. the transparent glass beads with the reflective coating on the lower (at least partial) surface are implanted (semi-embedded) into the long afterglow luminescence composite layer to block the excitation (sensitization) effect and afterglow luminescence effect of the long afterglow luminescence composite layer below the transparent glass beads, so that the long afterglow luminescence brightness and luminescence effect are influenced, particularly when the transferred substrate is dark color, the long afterglow luminescence effect after transfer is weakened, and the long afterglow luminescence brightness generally does not exceed the long afterglow luminescence brightness measured according to DIN 67510 standard100mcd/m 2 At present, the material is only used as a material with common decoration as a main part, and can not meet the high-standard requirements of special industries,
and because the long afterglow luminescent layer below the transparent glass microballoons is a light-colored inorganic layer, the light-reflecting effect is poor compared with a metal reflecting layer of aluminum powder or silver powder, and the light-reflecting brightness generally does not exceed 330 cd/(lx.m) according to the ENISO 20471 test standard 2 ）；
The existing products have one of the ideal performance of the luminous brightness and the reflection brightness, the other one is not ideal, or both are not ideal, thereby limiting the practical application range;
2. the reflective luminous hot-pressing transfer composite film comprises a mixed coating of long-afterglow luminous powder and bonding resin, the luminous brightness of the long-afterglow luminous coating is related to the addition amount of the long-afterglow luminous powder and the coating thickness, and particularly when the reflective luminous hot-pressing transfer composite film with high brightness is manufactured, because the shrinkage rates of the long-afterglow luminous powder, the bonding resin and a substrate material are different after hot-pressing transfer, a product is shrunk and wrinkled after washing and drying, the water washing resistance is poor, and the product can be washed for only 5-10 times according to the ISO 6330 international standard;
3. the reflective luminous fabric manufactured by the reflective luminous hot-press transfer composite film through hot-press transfer is poor in surface air permeability compared with the common fabric;
4. the surfaces of the existing products are flat, the stereoscopic impression is not strong, and the existing products are deficient in the aspect of manufacturing identification products such as LOG and the like;
5. the refraction and reflection of the transparent glass beads can influence human eye recognition and machine recognition (machine vision, night vision, infrared imaging recognition and the like), and the defects are more obvious.
Some attempts have been made to print a luminescent layer on the reflective fabric, but the luminescent layer has insufficient adhesion with the glass beads on the surface of the reflective fabric, and thus the reflective fabric is not resistant to washing.
In summary, in the existing reflective/luminescent hot-pressing transfer composite film, due to the structure (the reflective layer covers the luminescent layer), the reflective efficiency and the long-afterglow luminescent effect are affected, so that at least one of the luminescent brightness or the reflective brightness (the retroreflective efficiency) cannot meet various special requirements (especially under the condition of weak light source excitation) in the fields of special industries, lifesaving, emergency, police, military, transportation and the like, and especially the existing product cannot meet the requirement of technical fusion of intelligent wearable fabric and AI identification.
