Embodiment 1

[0018] The waterproof adhesive tape of the present invention comprises a layer of film layer, and the film layer is PU or PVC hot melt.

[0019] The adhesive film layer of the present invention is covered with a bottom layer, and the bottom layer is woven cloth or PU or PVC film.

[0020] The thermal sol of the present invention is a low-temperature, high-viscosity thermal sol.

Embodiment 2

[0021] The preparation method of embodiment 2 waterproof adhesive tape

[0022] The preparation method of the waterproof adhesive tape of the present invention comprises the steps of gluing, rewinding and cutting.

[0023] The gluing described in the preparation method of the present invention is to put the glue on the release paper on the coater, and dry the glue on the release paper through the oven of the coater to form a film layer. Cover the bottom layer when the glue film is formed.

[0024] The rewinding described in the preparation method of the present invention is that when the glue film is completely shaped and dried, the release paper is rewound with a rewinder, so that the glue film layer leaves the release paper and covers the bottom layer.

[0025] The slitting described in the preparation method of the present invention is to use a slitting machine to cut the film into strips.

Embodiment 3

[0026] Example 3 How to use the waterproof tape

[0027] The present invention also provides a method for using the waterproof tape, which is to cover the seamed seam of the waterproof cloth after the tape is heated and pressurized.

[0028] The use method of the present invention is to cover the adhesive tape on the sewn seam of the waterproof cloth through a hot air seam sealing machine.

[0029] As shown in Figure 2, the hot air seam sealing machine includes a waterproof tape conveying device 1, pressure wheels 2, 3 and hot air device 4 that rotate up and down in opposite directions, and the seam of the waterproof tape and cloth sprayed by hot air. The pinhole passes through the upper and lower pressure wheels at the same time, and the waterproof tape is pressed by two pressure wheels that rotate in opposite directions, and is attached to the pinhole on the seam.

[0030] The utility model is provided with two oppositely rotating pulling wheels 5, 6 behind the pressing whe...

Abstract

The invention discloses a waterproof gummed tape which comprises a latex film. The said film is made of PU or PVC thermosol and is produced by the steps of glue spreading, rewinding and slitting. In the invention, after heating and forcing, the said waterproof gummed tape is covered the stitch closure of proofed cloth such as rain overcoats and tents, after cooling, the waterproof gummed tape glue closely the stitch closure to stop the water drops from infiltrating into the stitch closure.

Description

technical field [0001] The invention relates to a waterproof adhesive tape and its preparation method and application, in particular to a waterproof adhesive tape used for seams of waterproof fabrics and its preparation method and application. Background technique [0002] Common waterproof fabrics, such as raincoats, tents, etc., need to be pasted with a waterproof tape on the stitched seam because water points are easy to penetrate from the needle hole. The waterproof adhesive tape often has the problem of poor bonding when the general waterproof adhesive tape is used. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the waterproof tape used on the seam of the existing waterproof cloth, and provide a waterproof tape and its preparation method and application. [0004] In order to solve the above problems, the present invention adopts the following technical solutions: [0005] The waterproof ad...
