A heat-resistant pressure-sensitive adhesive structure

Abstract

The invention relates to the technical field of pressure-sensitive adhesives, in particular to a heat-resistant pressure-sensitive adhesive structure, including a pressure-sensitive adhesive body, a pipe, and a storage box. The inside of the storage box is provided with a pipe, and the inside of the pipe runs from right to The left side is provided with a pressure-sensitive adhesive body and a push block in turn, and the pressure-sensitive adhesive body and the push block are movable. The pressure-sensitive adhesive body includes a base material layer, a high-temperature expansion adhesive layer, a first pressure-sensitive adhesive layer, a first The release film layer, the low-temperature expansion adhesive layer, the second pressure-sensitive adhesive layer and the second release film layer, the inside of the storage box is provided with a pressure-sensitive adhesive body. In the present invention, the high temperature resistance and weather resistance are improved by adding the aluminum foil and the base material layer, and at the same time, it has better shielding performance, improves the anti-aging performance, and makes it not easy to be corroded, and then uses the high temperature expansion adhesive layer and the low temperature expansion adhesive layer to make the Its paste filling is better and tighter, and it can increase its flame retardant and shockproof functions, and has a better protection function for high-temperature chemical pipelines.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to a heat-resistant pressure-sensitive adhesive structure. Background technique [0002] The pressure-sensitive adhesive tape is made by coating a pressure-sensitive adhesive on a tape-shaped substrate, which consists of a substrate layer, an adhesive layer and a peeling layer. The pressure-sensitive adhesive is the most important part of the pressure-sensitive adhesive tape. It has pressure-sensitive adhesive properties, and is mainly used as a base material such as fabric, plastic film, paper, etc. The prior art thermal insulation and sealing pressure-sensitive adhesive tape adopts biaxially oriented polypropylene film BOPP or biaxially oriented polyester. The film BOPET and other plastics are used as the base material, and the pressure-sensitive adhesive is coated on the base material. Since the plastic base material will soften when heated and brittle when c...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a heat-resistant pressure-sensitive adhesive structure, which has better high-temperature resistance and weather resistance, is less likely to be corroded, has better and tighter filling, increases its flame-retardant and shock-proof functions, and is suitable for high-temperature chemical The pipeline has the advantages of good protection function and easy storage and placement, which solves the problem that the traditional pressure-sensitive adhesive does not have shielding performance, is easy to be corroded, and easily causes the pressure-sensitive tape to break, and the pressure-sensitive adhesive has a single function
