[0002] Double-sided adhesive refers to a kind of adhesive strip or tape coated with adhesive on both sides. It has the characteristic of double-sided adhesion. When the double-sided adhesive is exposed to high temperature, the glue layer is prone to deformation and shrinkage when heated, resulting in relative displacement between the glue layer and the surface of the object, which in turn causes the glue layer to detach from the surface of the object.
[0003] Therefore, it is necessary to design a high-temperature anti-stripping double-sided adhesive to alleviate the above technical problems. Utility Model Content

[0006] Through the above technical solution, the thermal insulation layer is arranged in the glue layer, and the thermal insulation layer can reduce the heat transfer in the glue layer. At the same time, the grating on the surface of the thermal insulation layer reduces the deformation degree of the glue layer at high temperature, thereby reducing the impact of high temperature on the glue layer and reducing the viscosity between the double-sided adhesive and the object.
[0007] The utility model is further configured as follows: the grille is in a grid shape, and the thickness of the grille is half of a single glue layer.
[0008] Through the above technical solution, the grid-like grille divides the glue layer into multiple uniform parts, further reducing the degree of deformation of the glue layer due to heat, reducing the relative displacement between the glue layer and the surface of the object, thereby improving the adhesion of the glue layer at high temperatures.
[0009] The utility model is further configured as follows: the heat insulation layer is made of methyl vinyl silicone rubber material, and the surface of the heat insulation layer is subjected to corona treatment.
[0010] Through the above technical solution, the heat-insulating layer made of methyl vinyl silicone rubber material has high heat-insulating property, and the surface of the heat-insulating layer treated with corona can maintain high adhesion with the glue layer.
[0011] The utility model is further configured as follows: the upper and lower surfaces of the heat insulation layer are both configured to be wavy.
[0012] Through the above technical solution, the wavy surface of the heat insulation layer increases the contact area between the heat insulation layer and the glue layer, and further improves the bonding strength between the heat insulation layer and the glue layer.
[0013] The utility model is further configured as follows: a plurality of heat insulation grooves arranged along the length direction of the heat insulation layer are opened in the heat insulation layer, and the heat insulation grooves are equidistantly distributed in the width direction of the heat insulation layer.
[0014] Through the above technical solution, the heat insulation groove can reduce the heat transfer in the heat insulation layer, thereby reducing the heat conduction efficiency of the heat insulation layer.
[0015] The utility model is further configured as follows: aerogel is fixed in the heat insulation groove.
[0016] Through the above technical solution, aerogel has excellent thermal insulation properties, which further improves the thermal insulation capacity of the insulation layer.
[0017] The utility model is further configured as follows: the glue layer is made of polyimide glue.
[0018] Through the above technical solution, the glue layer made of polyimide glue has high heat resistance and is not easily deformed when heated, thereby improving the adhesion between the glue layer and the object.
[0019] The beneficial effects of the utility model are as follows: the heat insulation layer is arranged in the glue layer, the heat insulation layer can reduce the heat transfer in the glue layer, and at the same time, the grille on the surface of the heat insulation layer reduces the deformation degree of the glue layer at high temperature, thereby reducing the influence of high temperature on the glue layer and reducing the viscosity between the double-sided adhesive and the object. The aerogel has excellent heat insulation, which further improves the heat insulation capacity of the heat insulation layer. The glue layer made of polyimide glue has high heat resistance and is not easy to deform when heated, thereby improving the adhesion between the glue layer and the object.
