2. The heat and electrical conductive foam tape of claim 1, wherein: and a filter hole (8) is formed in the bottom of the bonding layer (7), and the bottom end of the PUR hot melt adhesive block (75) is in contact with the top of the filter hole (8).
3. The heat and electrical conductive foam tape of claim 1, wherein: the surface of the conduit (73) is extended with a shunt tube which is communicated with the aluminum-plastic structure shell (74) and forms a sealing cavity.
4. The heat and electrical conductive foam tape of claim 1, wherein: the bonding glue layers (6) are BSI glue, and the number of the bonding glue layers (6) is four.
5. The heat and electrical conductive foam tape of claim 1, wherein: the thickness of the adhesive layer (7) is 0.2CM-0.3CM.
6. A thermally and electrically conductive foam tape according to any one of claims 1-6, comprising the steps of:
s1, cutting the foam adhesive tape into the required size, and then heating one surface of an adhesive layer (7) to melt the hot melt adhesive block (71) structure and the PUR hot melt adhesive block (75) in the foam adhesive tape, so that the foam adhesive tape is gradually changed into a fluid from a solid and filtered out from a filter hole (8);
s2, wrapping and winding the foam adhesive tape which is well hot-melted and divided into proper sizes on electronic elements and circuits of electronic equipment to be protected and isolated, and protecting the required protection points in an annular wrapping mode.
7. The heat and electric conductive foam tape according to claim 6, wherein the disassembling method comprises the following steps:
step one, putting equipment provided with foam tapes into a low-temperature space at minus 60 ℃ for freezing for 12 hours, taking out, simultaneously injecting liquid nitrogen into a water absorption bin (72) by utilizing a low-temperature needle cylinder, adsorbing the liquid nitrogen by using fumed silica nano particles, and then forcefully pressing a foam integral structure to extrude the liquid nitrogen to rapidly cool the integral, so that a plastic-aluminum structural shell (74) is directly broken;
step two, after detecting that the aluminum-plastic structural shell (74) is completely broken, heating the whole foam, so that the hot melt adhesive is softened again, at the moment, the PUR hot melt adhesive block (75) still adheres to the electronic product, the foam adhesive tape at the top can be taken down, and then the PUR hot melt adhesive block (75) is cleaned to be disassembled.
