Embodiment 1

[0024] The preparation method of the flexible waterproof anti-folding sheet of embodiment 1 is characterized in that, comprises the following steps:

[0025] S1: Prepare two heat transfer films;

[0026] The preparation method of the heat transfer film is as follows: printing the ink on the release paper to form a pattern layer, and evenly spraying hot melt adhesive or hot melt adhesive powder on the pattern layer to form a hot melt adhesive layer;

[0027] S2: hot-melt lamination, the flexible skeleton layer is placed between the hot-melt adhesive layers of two heat transfer films, and then the laminated materials are placed in a hot press for heating and pressing to make a double-sided heat transfer Sheet;

[0028] S3: tear off the release paper on the outside of the double-sided heat transfer sheet to obtain a flexible, waterproof, and anti-folding sheet.

[0029] Wherein, the material of the hot melt adhesive or hot melt adhesive powder is selected from polyester, polyam...

Embodiment 2

[0034] The difference between embodiment 2 and embodiment 1 is that there is one heat transfer film and one release paper hot melt adhesive film, wherein the preparation method of the release paper hot melt adhesive film is: hot melt adhesive or hot melt adhesive powder is directly and evenly sprayed to cover On the release paper; using the same hot-press lamination method as in Example 1, the flexible skeleton layer is placed between the heat transfer film and the hot-melt adhesive layer of the release paper hot-melt adhesive film, and then the laminated material Place in a hot press to heat, press and bond to obtain a single-sided heat transfer sheet, and remove the release paper on the outside to obtain a waterproof and anti-folding sheet.

[0035] The skeleton layer in Example 2 is a composite structure of silica gel / paper / silica gel. The presence of the silica gel layer helps the paper to rebound after being folded and avoids obvious creases after the sheet is bent.

[00...

Embodiment 3

[0039] Embodiment 3 is based on Embodiment 1, the difference is that the frame layer is a polyester-cotton fabric, and the frame layer is provided with hollow holes. The cotton fiber content in polyester-cotton fabrics is 50%. The thickness of the polyester-cotton fabric is 0.3-0.35mm, and the thickness of the hot melt adhesive is 0.4mm.

[0040]The material of the hot-melt adhesive powder is polyurethane hot-melt adhesive powder; the melt index of the polyurethane hot-melt adhesive is 15-20g / 10min (150°C); the bonding temperature in S2 is 140-145°C, and the bonding pressure is 3Kg / cm 2 , the fitting time is 30s.

Abstract

The invention belongs to the technical field of sheets and discloses a manufacturing method for a flexible waterproof fracture-resisting sheet. The manufacturing method includes the steps of preparing heat transfer printing films, conducting hot melting and fitting and tearing off release paper. According to the manufacturing method for the flexible waterproof fracture-resisting sheet, a framework layer is a middle layer, waterproof hot melt adhesive layers are arranged on the two sides of the framework layer, the surface of each hot melt adhesive layer is printed with a pattern layer, and the sheet is manufactured through the double-sided heat transfer printing process. Compared with layer-by-layer blade coating in the prior art, by the adoption of the manufacturing method, few steps exist, the process is simple, and the production efficiency of the sheet can be improved. The invention further discloses a method for manufacturing a tag through the flexible waterproof fracture-resisting sheet.

Description

technical field [0001] The invention relates to the technical field of sheet materials, in particular to a preparation method of a flexible waterproof anti-folding sheet and a hanging tag. Background technique [0002] In the prior art, flexible, waterproof and anti-folding sheets such as advertising cloth, such as a kind of inkjet advertising cloth disclosed in CN201508673U, are made up of skeleton material and two layers of inkjet materials, and the two layers of inkjet materials are respectively heated with the two sides of the skeleton material by adhesive. Fusion fit. The inkjet material in the above structure uses polymer films such as polyvinyl chloride as the base material, and the adhesive between the inkjet material and the skeleton material can meet the requirements of stably bonding the two layers. The stiffness and mechanical properties are less affected. The flatness of the above advertising cloth mainly depends on the mechanical structure to fix and stretch ...
