Abstract

The invention relates to a sealant for a battery box and a preparation method thereof. An acrylate sealant for a battery box, comprising A component and B component; the A component and B component respectively include a special acrylate monomer, a multifunctional propionate monomer, an accelerator, an accelerator A tough resin and a stabilizer; the A component and / or the B component also include a molecular weight regulator; the molecular weight regulator is an acrylate containing a mercapto group. The acrylate sealant for battery boxes provided by the invention has short curing time, environmental protection in the curing process, low odor and excellent high and low temperature performance.

Description

technical field [0001] The invention relates to a sealant for a battery box and a preparation method thereof. Background technique [0002] The battery in the car power battery box usually generates heat due to work. With the increase of heat, the safety risk of the car increases. Therefore, the battery is usually cooled with liquid silicone oil or air cooling, and liquid cooling usually encounters sealing problems. In addition, after multiple batteries in the battery box are connected in series and parallel, there are positive and negative poles leading out on the top of the box, and at the same time, there are charging poles leading out from the side of each battery box. These poles are leading out from the battery box to The outside of the battery box is filled with liquid, so it is necessary to bond, fix and seal the above-mentioned poles of the battery on the outer box of the battery. In addition, due to the complex operating environment of electric vehicles, the seali...
