As a further technical scheme of the utility model, the surfaces of the first TPU coating, the second TPU coating and the PET base film are coated with acrylate adhesives, and release paper is attached through the acrylate adhesives.
Advantageous effects
The utility model provides a double-sided adhesive tape capable of being used for reworking foam. Compared with the prior art, the device has the following
The beneficial effects are that:
1. the utility model provides a but reworkable bubble cotton double-sided tape forms TPU crust layer after drying through first TPU coating and second TPU coating, and then has avoided the direct contact of bubble cotton layer and two sets of acrylic ester adhesive through first TPU coating and second TPU coating to realize separating glue film and substrate layer partition, and then be convenient for when needs heavy, can separate the crust layer and the bubble cotton layer that first TPU coating and second TPU coating formed through simple operation, thereby reach and be simple and convenient and be difficult to destroy by the article when heavy.
2. The utility model provides a but reworkable bubble is cotton double-sided tape, is through replacing the second TPU coating for transparent PET base film to laminate transparent PET base film through coating adhesive in the outside on the cotton layer of bubble, can be convenient when heavy with PET base film and the cotton layer separation of bubble be difficult to destroy by the article, and because PET base film has toughness, tensile strength and impact strength, thereby can increase double-sided tape overall structure's intensity.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
Referring to fig. 2, the present utility model provides a technical solution for a double-sided adhesive tape of reworkable foam: the utility model provides a can heavily worker bubble cotton double-sided tape, includes bubble cotton layer 1, and bubble cotton layer 1's upper surface coating has first TPU coating 4, and bubble cotton layer 1's lower surface coating has second TPU coating 5, and first TPU coating 4 and second TPU coating 5 are the same material, and thickness size is the same, and first TPU coating 4 and second TPU coating 5's surface all coats acrylate adhesive 2, and all has release paper 3 through the laminating of acrylate adhesive 2.
It should be noted that, foam layer 1, first TPU coating 4 and second TPU coating 5 form foam structure, form TPU crust layer after first TPU coating 4 and second TPU coating 5 are dry, and then avoid foam layer 1 and two sets of direct contact of acrylic ester adhesive 2 through first TPU coating 4 and second TPU coating 5, thereby realize separating glue film and substrate layer partition separation's effect, and then be convenient for when needs heavy, can separate the crust layer that first TPU coating 4 and second TPU coating 5 formed with foam layer 1 through simple operation, thereby reach when heavy simple and convenient and be difficult to destroy by the article.
