Abstract

The invention discloses a UV adhesive for protecting an exposed aluminum layer of a battery aluminum-plastic film and a use method of the UV adhesive, and the UV adhesive comprises a monomer, an oligomer, a photoinitiator and an auxiliary agent. The formula of the monomer is prepared from the following raw materials: 10 to 20 parts of isobornyl acrylate, 20 to 30 parts of lysine diisocyanate, 20 to 30 parts of tripropylene glycol diacrylate, 10 to 20 parts of polyisocyanate and 10 to 20 parts of trimethylolpropane triacrylate. The adhesive mainly comprises the monomer, the oligomer, the photoinitiator and the auxiliary agent, when the adhesive is used, the position, needing adhesive dispensing, of a battery is wiped firstly, then the battery is clamped and fixed through a clamping block, the adhesiveness between an adhesive solution and an aluminum plastic film can be improved, finally UV illumination is conducted through a UV machine, the adhesive solution is cured, and the cured adhesive cannot become brittle; and the characteristic indexes of adhesive force, shrinkage rate, impact resistance, scratch resistance and weather resistance of a radiation curing coating are improved to a certain extent, and meanwhile, the impact resistance of cured glue is improved.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a UV glue for protecting the exposed aluminum layer of a battery's aluminum-plastic film and a use method thereof. Background technique [0002] In battery production, the exposed aluminum layer of the battery's aluminum-plastic film must be covered and protected to prevent electrostatic leakage and moisture infiltration of the aluminum layer, and improve battery safety and reliability. However, in the prior art, the battery application bonding substrate is an adhesive and an aluminum-plastic film, and the adhesion between the adhesive and the aluminum-plastic film is poor and the impact resistance is low, resulting in the use process, if When impacted by an external force, delamination is prone to occur between the adhesive and the aluminum-plastic film. [0003] For this reason, we propose a UV glue for protecting the exposed aluminum layer of battery aluminum-pl...
