Problems solved by technology

The current phase change energy storage adhesives either have good fluidity, but the amount of phase change material added is small, and the energy storage effect is poor; or the amount of phase change material added is sufficient, but the viscosity and thixotropy of the adhesive are extremely high. Large, non-flowing, and even some phase change materials will cause the adhesive system not to cure

Abstract

The invention discloses an adhesive with an energy storage function and application thereof. The adhesive comprises an adhesive matrix and an energy storage microcapsule; the energy storage microcapsule comprises a wall material and a core material; the wall material is a terpolymer of resorcinol, urea and aldehyde; the core material is a phase change energy storage material; the content of nitrogen in the wall material is less than or equal to 12 wt%. According to the adhesive with the energy storage function and the application thereof provided by the technical schemes of the invention, phenol serves as a third monomer to be copolymerized with the urea and aldehyde to prepare the microcapsule wall material, meanwhile, the content of nitrogen in the microcapsule wall material is reduced, and a prepared energy storage microcapsule can be applied to preparation of the adhesive; the prepared adhesive with the energy storage function has the advantages of low thixotropy, good flowing property, high phase change material content, good energy storage effect and the like.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an adhesive with energy storage function and its application. Background technique [0002] According to the "Guidelines for the Development of Electric Vehicle Charging Infrastructure 2015-2020", the number of domestic electric vehicles is expected to reach 5 million in 2020. As the main energy storage component of electric vehicles, power batteries directly affect the performance of electric vehicles. When the vehicle is running on different road conditions, the battery pack will be discharged at different rates, and a large amount of heat will be generated at different heat generation rates, resulting in excessive internal temperature of the battery pack and uneven temperature distribution, affecting the safety and security of the power battery system. reliability. Therefore, it is very important to choose a suitable thermal management system for power batteries. Common t...
