[0002] Silicone tape is a type of tape that is resistant to acid and alkali corrosion and has a good effect for outdoor use. It is divided into one-component silicone glue and two-component silicone glue. When using it, gently apply force to stretch the tape. The last circle of tape must not be stretched. To prevent the tape from lifting off, press the tape until it melts and sticks together. Currently, silicone tapes are becoming more and more mature and have a certain high temperature resistance effect. They can be used at H-level high temperatures of 250°C (365°F). However, they lack effective thermal insulation structures. The continuous presence of heat will cause the silicone tape to age faster, reduce its performance, and affect its service life.

DETAILED DESCRIPTION

[0015] like Figure 1 and Figure 2 As shown, a thermal insulation silicone tape comprises a tape body 1, wherein the tape body 1 comprises a substrate layer 11, a release paper layer 12 arranged under the substrate layer 11, and an adhesive layer 13 used to connect the release paper layer 12 and the substrate layer 11, characterized in that: a first thermal insulation layer 14 is arranged on the substrate layer 11, a silicone layer 15 is arranged on the first thermal insulation layer 14, a second thermal insulation layer 16 is arranged on the silicone layer 15, and a heat reflection layer 17 is arranged on the second thermal insulation layer 16.

[0016] When in use, after tearing off the release paper layer 12, the tape body 1 can be bonded by the adhesive layer 13, and the first thermal insulation layer 14 and the second thermal insulation layer 16 make the tape body 1 have a good thermal insulation effect. The heat reflection layer 17 reflects light to reduce the conversion of heat-generating light into heat on the applied object, thereby further improving the thermal insulation effect of the tape body 1. The utility model can effectively isolate external heat, avoid the accelerated aging of the silicone tape due to the continuous presence of heat, and extend the service life of the silicone tape.

[0017] like Figure 1 and Figure 2 As shown, the first thermal insulation layer 14 includes an upper metal thermal insulation film layer 141 and a lower metal thermal insulation film layer 142 arranged vertically opposite to each other, and two transverse flexible organic modified silicone strips 143 are used to connect the upper metal thermal insulation film layer 141 and the lower metal thermal insulation film layer 142, and the two transverse flexible organic modified silicone strips 143 are connected by a plurality of longitudinal flexible organic modified silicone strips 144, and the top and bottom ends of the longitudinal flexible organic modified silicone strips 144 are respectively connected to the upper metal thermal insulation film layer 141 and the lower metal thermal insulation film layer 142, and the two transverse flexible organic modified silicone strips 143 and the adjacent two longitudinal flexible organic modified silicone strips 144 are connected to each other. A plurality of thermal insulation spaces are formed between the organic modified silicone strip 144, the upper metal thermal insulation film layer 141 and the lower metal thermal insulation film layer 142, and the thermal insulation spaces are filled with nitrogen. The upper side of the upper metal thermal insulation film layer 141 is bonded to the silicone layer 15, and the lower side of the lower metal thermal insulation film layer 142 is bonded to the substrate layer 11. In this embodiment, a plurality of thermal insulation spaces are formed by two transverse flexible organic modified silicone strips 143, two adjacent longitudinal flexible organic modified silicone strips 144, the upper metal thermal insulation film layer 141 and the lower metal thermal insulation film layer 142, and the thermal insulation spaces are filled with nitrogen, so that the tape body 1 has a good thermal insulation effect.

[0018] like Figure 1 and Figure 2 As shown, the transverse flexible organic modified silicone strip 143 is arranged parallel to the length direction of the tape body 1; in this embodiment, when the transverse flexible organic modified silicone strip 143 is arranged parallel to the length direction of the tape body 1, the longitudinal flexible organic modified silicone strip 144 is arranged perpendicular to the length direction of the tape body 1, thereby reducing the loss of nitrogen when the tape body 1 is cut.

In this embodiment, the water-based epoxy resin layer 61 made of water-based epoxy resin itself has a good thermal insulation effect. By filling the hollow glass microspheres 62 in the water-based epoxy resin layer 61, the contact area of ​​heat transfer is reduced, thereby further improving the thermal insulation effect of the water-based epoxy resin layer 61.
