NOVELTY - Lithium battery double-sided hot melt adhesive based on high bonding force under heat stability, comprises a base film, where the base film is sent to the proton irradiation box for irradiation treatment into 5-7 times of dipping agent for dipping treatment, finishing dipping, then double-layer coating EVA hot melt colloid, the coating thickness is 0.1-0.3 mm. The preparation method of the impregnating agent is: adding 5-10 pts. wt. silane coupling agent KH570 into 15-25 pts. wt. sodium alginate solution, stirring for 10-20 minutes at a rotating speed of 450-550 revolutions/minute, stirring to finish, and (ii) adding 3-6 pts. wt. modified bentonite an d1-5 pts. wt. lanthanum sulfate, and stirring and mixing fully at a rotating speed of 100-400 revolutions/minute, stirring for 35-45 minutes and stirring. USE - Lithium battery double-sided hot melt adhesive based on high bonding force under heat stability. ADVANTAGE - Lithium battery double-sided hot melt adhesive improves surface activity, flake structure, enhances the barrier of the product to prevent heat transfer, and enhances the thermal stability and adhesive strength of the product.
