Embodiment 1
[0060]An adjustable adhesive grid exhaust tape comprising a polyimide film and a high temperature thermal melt glue having a solid content of 35.7%, and the rubber surface of the tape is a grid.
[0061] Further, high temperature hot melt adhesives include the following raw materials, according to the weight:
[0062]
[0063] The method of preparing the above-mentioned adhesive grating veneer, including the following steps:
[0064] Step (1): The high-temperature hot melt is directly applied directly to the surface of the polyimide film of 25 μm, and then drying the thickness of 5 μm at 110 ° C to give a prefabricated tape having a thickness of 30 μm;
[0065] Step (2): Eliminate the preposition of the prefabricated tape through the roller roller, so that the glue surface is pressed into a grid, obtain a roller tape, and then retract the roll tape, rewind, and obtain the finished tape.
[0066] Wherein, the roller has a grid pressure roller having a convex body strip parallel t...
Embodiment 2
[0068] An adjustable adhesive grid exhaust tape comprising a polyimide film and a high temperature hot melt glue.
[0069] The difference from Example 1 is that the high temperature thermal melt glue solid content is 20%, and the feedstock is measured by weight:
[0070]

Abstract
The invention discloses a viscosity-adjustable grid exhaust adhesive tape and a preparation method thereof, and the viscosity-adjustable grid exhaust adhesive tape comprises a polyimide film and a high-temperature hot melt adhesive with the solid content of 20-40%. The method for preparing the viscosity-adjustable grid exhaust adhesive tape comprises the following steps: (1) directly coating the surface of the polyimide film with the high-temperature hot melt adhesive, and then drying at 100-130 DEG C to form an adhesive layer, so as to obtain a prefabricated adhesive tape; and (2) rolling the adhesive layer of the prefabricated adhesive tape through a grating roller so that the adhesive surface is pressed into a grating shape to obtain a rolled adhesive tape, and then rolling and rewinding the rolled adhesive tape to obtain a finished adhesive tape product. According to the viscosity-adjustable grid exhaust adhesive tape and the preparation method thereof provided by the invention, the rewinding meter number of the adhesive tape is long, bubbles are avoided, the normal-temperature viscosity is low, and the high-temperature viscosity is high.
Description
Technical field [0001] The present invention belongs to the technical field of tape, and is specific to an adjustable adhesive grid exhaust tape and a preparation method thereof. Background technique [0002] The current demand for social power batteries is increasing, and the global power battery demand measurement increases from 100 to 200GWH. In this social context, the demand for battery tape will increase. At present, there is a highly viscous mass, short meter, and a short bubble, and cannot fully meet the technical standards of power batteries. [0003] The application number is 201921798990.2, and the name is a utility model with a high-temperature resistant to high temperature tweeral tape. The thermal stability is used to combine the multilayer structure of other material layers such as high temperature silica gel. The high temperature silica gel layer and the silicone layer are made of a silica gel bump rather than the entire surface to make the gap between the silica ...
