Abstract

The invention belongs to the IPC classification number of C09J133 / 08, and particularly relates to a hot-melt pressure-sensitive adhesive for assembling a new energy battery and a preparation method of the hot-melt pressure-sensitive adhesive. The hot-melt pressure-sensitive adhesive is prepared from the following raw materials in parts by weight: 1-15 parts of liquid resin, 25-55 parts of rubber and 30-60 parts of tackifying resin. The hot-melt pressure-sensitive adhesive provided by the invention has good shearing force and drawing force.

Description

technical field [0001] The IPC classification number of the invention is C09J133 / 08, and specifically relates to a hot-melt pressure-sensitive adhesive for assembling a new energy battery and a preparation method thereof. [0002] technical background [0003] The new energy vehicle battery pack is assembled from a single battery, and the batteries need to be bonded and fixed. At present, some acrylic pressure-sensitive adhesives are often used in the market to realize the fixing of the batteries. [0004] CN112126384A uses acrylate adhesive to prepare acrylate insulating flame retardant pressure-sensitive adhesive to realize the bonding of batteries, but some solvent is needed during use. This is because this type of pressure-sensitive adhesive is diluted with solvent at high temperature during use. Adhesive performance is reduced. SUMMARY OF THE INVENTION [0005] In order to solve the above technical problems, a first aspect of the present invention provides a hot-melt ...
