Abstract
Description
Technical Field
[0001] This utility model relates to the field of transfer paper technology, and in particular to a moisture-proof transfer paper. Background Technology
[0002] As an important medium for transferring images and text, transfer paper is widely used in food packaging, cosmetic labels, furniture decoration, and electronic product casing printing. Its core function is to accurately transfer patterns to the surface of the substrate through processes such as heat transfer and water transfer. Therefore, it has high requirements for the stability, weather resistance, and moisture-proof performance of the paper. For example, a Chinese patent discloses a water-locking, moisture-proof, heat-sealed, sublimation transfer paper with application number 202022496871.0. It achieves water-locking and moisture-proofing through three hydrophobic rings, and at the same time, it uses nine grooves to seal water vapor during the heat-pressing dye sublimation process, so that the pattern transfer process is completed efficiently and stably, and the transfer quality is fully guaranteed. However, this solution only applies moisture-proofing treatment to the front and back of the transfer paper and the heat-pressing contact surface. The side edges are not sealed. In high-humidity environments, moisture can easily seep in from the fiber gaps on the side of the paper, causing dye migration or mold growth on the base layer in the edge area, affecting the overall moisture-proof performance and the uniformity of transfer accuracy. Utility Model Content
[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a moisture-proof transfer paper. The waterproof film and the oil paper layer respectively block the liquid water above and the moisture at the bottom. If moisture seeps in from the side, the moisture-proof coating layer first physically adsorbs the moisture, and the moisture-proof layer then chemically adsorbs the moisture to strengthen the protection. The hollow structure of the support column guides the moisture to flow quickly to the moisture-absorbing rod. The calcium chloride fiber rod in the rod solidifies the moisture into a gel through a deliquescence reaction. The staggered moisture-absorbing units promote internal air convection and ensure uniform moisture absorption.

The outer circumferential surface of the water-absorbing rotating rod is provided with a fiber water-absorbing layer, and the water-absorbing rotating rod can contact the surface of the transfer paper to absorb any moisture that may be present on the surface, thereby further protecting the transfer paper from moisture.
[0006] According to the present invention, a moisture-proof transfer paper is provided with a rotating roller rotatably mounted on the outer circumferential surface of the fixed roll. The main body of the transfer paper is spirally wound around the outer circumferential surface of the rotating roller, and the two ends of the rotating roller are rotatably connected to the inner wall of the roll housing through bearings, so that the transfer paper rotates smoothly during winding and use, reducing damage to the transfer paper caused by friction and jamming.
[0007] According to the present invention, the axial length of the absorbent rod is greater than the width of the transfer paper body, ensuring that the absorbent rod can completely cover the width direction of the transfer paper, effectively absorbing moisture from all positions on the surface of the transfer paper, and avoiding dead spots in water absorption.
[0008] According to the present invention, the moisture-proof transfer paper has a hollow cylindrical structure made of polypropylene.
[0009] According to the present invention, the moisture-proof transfer paper has a moisture-absorbing rod made of calcium chloride fiber rod, which is fixedly connected to the center of the support column, and the length of the moisture-absorbing rod is the same as the height of the support column.
[0010] Beneficial effects: This utility model, through the setting of moisture-proof components and other structures, forms the first line of defense with a waterproof film and an oil-paper layer, respectively blocking liquid water above and moisture at the bottom. When moisture enters the interior of the transfer paper through the tiny pores on the side, the moisture-proof coating layer first adsorbs water molecules, and then the moisture-proof layer further absorbs moisture through chemical adsorption. The hollow structure of the support column forms a moisture channel, accelerating the migration of moisture to the moisture-absorbing rod. The calcium chloride fiber rod converts moisture into gel through a deliquescence reaction. The moisture-absorbing units in the moisture-proof components are arranged in an alternating pattern, so that moisture forms convection inside the transfer paper, improving the uniformity of moisture absorption.

When moisture enters the interior of the transfer paper through the tiny pores on the side, the moisture-proof coating layer 201 first adsorbs water molecules, and then the moisture-proof layer 202 further absorbs moisture through chemical adsorption. The hollow structure of the support column 203 forms a moisture channel, accelerating the migration of moisture to the moisture-absorbing rod 204.
