The existing foam adhesive tape is usually made by coating a solvent type (or hot melt type) pressure sensitive adhesive on two sides of a base material such as PE, PO, EVA and the like, and then coating release paper on the two sides, wherein the adhesive is acrylic acid (or rubber) system. The existing foam adhesive tape needs to be soaked by a solvent in the removing process, or is easy to generate adhesive residue, break or be unremovable. On some large building materials or equipment, removability is hardly achieved. Meanwhile, most of the existing products have no heat conduction function and cannot provide a good heat dissipation function, and the existing heat conduction foam adhesive tape can realize the heat conduction function, but is complex to process and high in cost.

the utility model provides a can remove acrylic acid foam adhesive tape, includes the substrate layer, the both sides of substrate layer are provided with pressure sensitive adhesive layer, pressure sensitive adhesive layer keeps away from one side of substrate layer is provided with from type rete, pressure sensitive adhesive layer component includes butyl acrylate, acrylic acid, curing agent, heat conduction powder, foaming microballon, glass microballon and solvent.
The substrate layer is polycarbonate or polyurethane.
The heat conducting powder is metal oxide or nitride.
D (95) of the foaming microspheres is 9-11um, wherein D (95) represents that the proportion of the foaming microspheres meeting the particle size range is more than or equal to 95 percent.
The diameter of the glass beads is 20 um.
By weight, 90-100 parts of butyl acrylate, 0-10 parts of acrylic acid, 0-10 parts of curing agent, 20-40 parts of heat conducting powder, 1-10 parts of foaming microspheres, 1-20 parts of glass beads and 100-200 parts of solvent.

Detailed Description
The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.
As shown in fig. 1, the invention discloses a removable acrylic foam adhesive tape, which comprises a substrate layer, wherein the substrate layer is polycarbonate or polyurethane, preferably a modified polyurethane film, and provides a certain stretching rate in a stretching process. The both sides of substrate layer are provided with pressure sensitive adhesive layer, and one side that pressure sensitive adhesive layer kept away from the substrate layer is provided with from type rete. The pressure-sensitive adhesive layer is selected from acrylate adhesives, and comprises the following components in parts by weight: 90-100 parts of butyl acrylate, 0-10 parts of acrylic acid, 0-10 parts of a curing agent, 10-30 parts of heat conducting powder, 1-10 parts of foaming microspheres, 1-20 parts of glass beads, 100-200 parts of a solvent and 100-500 mu m in total thickness.
The heat conducting powder is metal oxide or nitride, and provides heat conducting performance. The foaming material is foaming microsphere D (95) approximately equal to 9-11um, the low-particle-size microsphere is beneficial to coating of an adhesive layer, and the foaming multiplying power of an internal plate of acrylic acid is effectively controlled, so that the sample has certain energy-absorbing and shock-absorbing advantages compared with the traditional adhesive tape. The glass beads D are 20um and are used for reducing the viscosity of the adhesive layer in the stretching process. The solvent includes ethyl acetate, toluene or methyl ethyl ketone.
The key point of the technology of the invention is physical viscosity reduction, the adhesive tape becomes thinner and thinner under the condition of being capable of being pulled up, and the pulling up property of the adhesive tape is improved by the ultrathin polyurethane film; after stretching to a certain degree, the glass beads are slightly convex on the surface of the adhesive tape (refer to fig. 1), so that the bonding surface of the adhesive tape is reduced, and the removability is achieved.
The prepared adhesive tape is subjected to performance test, the performance test results of the prepared double-sided adhesive tape and a control group double-sided adhesive tape are shown in fig. 2, the addition of the heat conduction powder enables the heat conduction performance of the adhesive tape prepared by the invention to be excellent, the elongation at break of the double-sided adhesive tape prepared by the invention is obviously enhanced by adopting the ultrathin polyurethane substrate and the glass beads, and the double-sided adhesive tape can be easily pulled out when the adhesive tape is removed at 0-60 degrees.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
