Problems solved by technology

[0003] Temperature-controlled tapes often use heat-sensitive materials mixed in the adhesive layer to achieve the temperature-controlled discoloration function. The raw materials in the adhesive layer are likely to affect the distribution of heat-sensitive materials, and the heat-sensitive materials are agglomerated, resulting in insensitive discoloration, which limits the temperature-controlled tape. usage of

Abstract

The invention discloses an intelligent temperature-control adhesive tape, comprising an adhesive tape base body, and an adhesive layer is coated on the adhesive tape base; the adhesive layer comprises the following raw materials in parts by weight: 40-50 parts of epoxy resin, 10-20 parts of cross-linking modification liquid parts, 5-10 parts of modified heat-sensitive material, 3-6 parts of polyester polyol, 1-5 parts of polyethylene glycol, and 1-2 parts of rare earth liquid. The intelligent temperature control tape of the invention adopts epoxy resin as the matrix, and prepares an adhesive layer by cooperating with raw materials such as cross-linking modification liquid and modified heat-sensitive material. The addition of rare earth liquid has the effect of activating raw materials and enhancing the reaction force between raw materials. , and then plasma treatment is performed on the tape substrate, so that the microstructure activity changes, and the bonding strength between the adhesive layer and the tape substrate is improved.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an intelligent temperature-controlled adhesive tape and a production process thereof. Background technique [0002] Adhesive tape is composed of two parts: substrate and adhesive, which connect two or more disjoint objects together by bonding. Its surface is coated with a layer of adhesive. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because their own molecules form bonds with the molecules of the object to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive, according to different brands, different types, there are various polymers. [0003] Temperature control tapes are often mixed with heat-sensitive materials in the adhesive layer to realize the function of tem...
