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 which comprises an adhesive tape base body, and the adhesive tape base body is coated with an adhesive layer. The adhesive layer is prepared from the following raw materials in parts by weight: 40 to 50 parts of epoxy resin, 10 to 20 parts of crosslinking modified liquid, 5 to 10 parts of modified heat-sensitive material, 3 to 6 parts of polyester polyol, 1 to 5 parts of polyethylene glycol and 1 to 2 parts of rare earth liquid. According to the intelligent temperature control adhesive tape, epoxy resin is adopted as a matrix and matched with raw materials such as cross-linking modified liquid and a modified heat-sensitive material to prepare the adhesive layer, the rare earth liquid is added, the raw material activating effect is achieved, the reaction force between the raw materials is enhanced, plasma treatment is conducted on the adhesive tape matrix, and therefore the microstructure activity is changed, and the temperature control effect is improved. The bonding strength of the adhesive layer and the adhesive tape base body 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, base material and adhesive, and two or more unconnected objects are connected 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 of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive has various polymers according to different brands and types. [0003] Temperature-controlled tapes often use heat-sensitive materials mixed in the adhesive layer to achieve th...
