Abstract

The invention discloses a preparation method of a coloring composite adhesive. The method comprises the following steps: (a) taking a connecting resin, a dispersing agent, an organic pigment and an organic solvent A, performing mixing according to a mass ratio of the connecting resin to the dispersing agent to the organic pigment to the organic solvent A of (5-10):(0.5-2):(5-15):(60-90) to obtaina mixture A; (b) putting the uniformly-dispersed mixture A into a sand mill, and performing grinding until the particle size D90 of the ground mixture A is 500 nm or less to obtain a highly-dispersible pigment; and (c) taking matrix resin, a crosslinking agent, the highly-dispersible pigment and an organic solvent B, performing mixing according to a mass ratio of the matrix resin to the crosslinking agent to the highly-dispersible pigment to the organic solvent B of (40-60):(5-20):(40-60):(0-250) to obtain a mixture B to prepare the coloring composite adhesive, wherein the solid content of themixture B is 15-60%. According to the preparation method provided by the invention, the coloring composite adhesive obtained by the method can make the obtained aluminum-plastic composite film have arequired color, shortens a technological process of the colored aluminum-plastic composite film after bonding with an outer protective layer and a middle layer, and greatly reduces the production costs, thereby meeting requirements of mass production.

Description

technical field [0001] The invention relates to a composite glue, in particular to a preparation method of a colored composite glue. Background technique [0002] Lithium-ion batteries have become the main force in the battery industry due to their high output voltage, large specific energy, and long cycle life. Especially among the current commercialized rechargeable batteries, polymer lithium-ion batteries have the highest specific energy density, which can Realizing the thinning of rechargeable batteries has developed rapidly in recent years. According to the different lithium battery shells, lithium-ion batteries can be divided into three types: cylindrical, square, and soft-packed. The soft-packed lithium battery shell is becoming the future of lithium batteries due to its easy-to-change shape and high specific energy of the monomer. A development trend. Soft-pack lithium battery shells generally use aluminum-plastic composite films. At present, aluminum-plastic compo...
