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.

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.
