Embodiment 1

[0024] Such as figure 1 As shown, a high-temperature-resistant adhesive tape includes a base material 1 and a glue layer 2. The glue layer 2 is located at the bottom of the base material 1. A temperature-insulating layer 3 is arranged inside the base material 1. The temperature-insulating layer 3 is made of ceramic fiber interlayer 4, rock wool Interlayer 5 and phenolic resin interlayer 7 are composed, the bottom of ceramic fiber interlayer 4 is bonded with phenolic resin interlayer 7 , the bottom of phenolic resin interlayer 7 is bonded with rock wool interlayer 5 , the shape of phenolic resin interlayer 7 is set in an arc shape, and the bottom of temperature insulation layer 3 is Centrifugal glass wool interlayer 6 is bonded, substrate 1 has a thickness of 17 μm, temperature insulation layer 3 has a thickness of 10 μm, ceramic fiber interlayer 4 has a thickness of 4 μm, rock wool interlayer 5 has a thickness of 4 μm, and phenolic resin interlayer 7 has a thickness of The thi...

Embodiment 2

[0027] Such as figure 1 As shown, the bottom of the centrifugal glass wool interlayer 6 is provided with a through hole one 8 and a through hole two 9, the through hole one 8 is located on the side of the through hole two 9, the glue layer 2 is bonded to the centrifugal glass wool interlayer 6 through the through hole one 8, The glue layer 2 is bonded to the rock wool interlayer 5 through the centrifugal glass wool interlayer 6 through the through hole two 9, the diameter of the through hole one 8 is 4 μm, and the length of the through hole one 8 is 1 μm, and the diameter of the through hole two 9 is 4 μm , and the length of the second through hole 9 is 4 μm.

[0028] In this embodiment, by setting the first through hole 8 and the second through hole 9, the adhesion between the glue layer 2 and the base material 1 can be effectively improved, and the glue layer 2 and the base material 1 can be prevented from being separated from the glue layer 2 after long-term use of the adhe...

Embodiment 3

[0030] Such as Figure 1-2 As shown, the outer surface of the substrate 1 is provided with a fireproof layer 10, the fireproof layer 10 is composed of a fireproof flame retardant coating 11 and a fireproof coating 12, the fireproof flame retardant coating 11 is located on one side of the fireproof coating 12, and the fireproof layer 10 The thickness of the fire retardant coating 11 is 5 μm, the thickness of the fire retardant coating 11 is 2.5 μm, and the thickness of the fire protection coating 12 is 2.5 μm.

[0031] In this embodiment, the fireproof and flame retardant properties of the adhesive tape are effectively improved through the fireproof layer 10 .

[0032] It should be noted that the present invention is a high temperature resistant adhesive tape. During operation, the temperature insulation layer 3 inside the substrate 1 includes ceramic fiber interlayer 4, rock wool interlayer 5 and phenolic resin interlayer 7, all of which have very good high temperature resista...

Abstract

The invention discloses a high-temperature-resistant adhesive tape. The adhesive tape comprises a substrate and an adhesive layer, wherein the adhesive layer is located at the bottom of the substrate,a thermal insulation layer is arranged in the substrate and consists of a ceramic fiber interlayer, a rock wool interlayer and a phenolic resin interlayer, the phenolic resin interlayer is bonded tothe bottom of the ceramic fiber interlayer, the rock wool interlayer is bonded to the bottom of the phenolic resin interlayer, and the phenolic resin interlayer is arc-shaped. By arrangement of the thermal insulation layer, the high temperature resistance of the adhesive tape is effectively improved and the use range of the adhesive tape is expanded; by arrangement of through holes I and II, the bonding property between the adhesive layer and the substrate is effectively enhanced, and separation of the adhesive layer from the substrate due to long-term use of the adhesive tape is avoided; by the aid of a fireproof layer, fireproof and flame-retardant performance of the adhesive tape is effectively improved, and the adhesive tape is suitable to be widely promoted and used.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a high temperature resistant adhesive tape. Background technique [0002] Adhesive tapes can be divided into high temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, and die-cut tapes according to their functions. Different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to the object. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of the adhesive; in modern times, various polymers are widely used. [0003] However, general adhesive tapes do not have the performance of high temperature resistance, and the long-term use of the adhesive tape will easily cause the base material to separate from the glue layer, and it does not have fireproof performance. To this end, we propose a high temperature resistant adhes...
