Abstract

The thermochromic adhesive tape sequentially comprises a base material layer, a permeable layer, a porous membrane, a coloring layer and a release layer from top to bottom, the permeable layer comprises a macromolecule pressure-sensitive adhesive and a crystalline material, the crystalline material is dispersed in the macromolecule pressure-sensitive adhesive, the crystalline material can permeate into the porous membrane after being heated and melted, and the porous membrane is coated with the colored layer. The permeable layer is obtained by drying permeable layer glue, and the permeable layer glue is prepared from the following components in parts by weight: 100 parts of a polymer pressure-sensitive adhesive, 20-100 parts of a crystalline material, 0.1-5 parts of an antioxidant, 0.1-5 parts of 6-(2-benzotriazolyl)-4-tert-octyl-6-tert-butyl-4-methyl-2, 3, 5-triazolyl)-4-(2-benzotriazolyl)-4-(2-benzotriazolyl)-4-(2-benzotriazolyl)-4-(2-benzotriazolyl)-4-(2-benzotriazolyl)-4-(2-benzotriazolyl)-4-( The adhesive tape disclosed by the invention has a color changing function, is very sensitive to temperature induction, can monitor the temperature of a working environment in time, is stable in viscosity, does not have relatively large fluctuation along with the change of the temperature, and does not influence the use even if the temperature is increased.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to a thermochromic adhesive tape and a preparation method thereof. Background technique [0002] In a volt power station, it is necessary to rely on cables and connectors to collect the power of a large number of components and enter the inverter. Photovoltaic connectors are key parts for the interconnection of various components such as components, combiner boxes, controllers and inverters in photovoltaic power generation systems. The voltage on the DC side of the entire photovoltaic system is usually as high as 1000V or more. Once the joints of the photovoltaic modules are loose and the contact is poor, it is very easy to cause DC arcing. DC arcing will cause the temperature of the contact part to rise sharply, and the continuous arc will generate a high temperature of 1000-3000 ° C, accompanied by high temperature carbonization of the surrounding components. In the light ...
