Abstract
The invention relates to the technical field of adhesive tapes, in particular to a temperature-change flame-retardant pressure-sensitive adhesive tape and a preparation method thereof. The pressure-sensitive adhesive layer in the temperature-change flame-retardant pressure-sensitive adhesive tape of the invention comprises the following raw materials by mass percentage: adhesive 30-50%, cure agent0.01-0.05%, solvent 30-50%, flame retardant 5-15% and temperature change pigment 5-15%, and that color change range of the temperature change pigment of the present invention is 100-150 DEG C, according to the color change, timely warning can be performed, so that operators have time to respond, and the adhesive tape is safe to use. The preparation method of the temperature--change flame-retardant pressure-sensitive adhesive tape is simple in process and easy to operate, meets the requirements of industrial production, and the prepared adhesive tape can be temperature-varying and has good flame retardant performance.
Description
technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a temperature-varying flame-retardant pressure-sensitive adhesive tape and a preparation method thereof. Background technique [0002] Polyimide tape is a material made of polyimide film coated with pressure-sensitive adhesive on one or both sides and vulcanized by heat. It has excellent mechanical properties, electrical properties, moisture resistance and thermal stability, and has been widely used in Insulation of welding machines, transformers and capacitors. [0003] Although the traditional polyimide tape is resistant to high temperature, its flame retardant effect is average. However, polyimide tape is mainly used in high temperature and high pressure locations. Not safe enough. [0004] In view of the above technical problems, it is necessary to provide a new adhesive tape to better solve the above technical problems. Contents of the invention [0005] In order...
