The invention belongs to the field of organic synthesis, and relates to a polymer modification technology, in particular to a high-temperature-resistant lithium battery aluminum plastic film inner layer adhesive and a preparation method thereof. The invention relates to an inner-layer adhesive for an aluminum-plastic film of a lithium battery, which is obtained by grafting and modifying chlorinated polyolefin and polyolefin as raw materials in the presence of unsaturated acid by a solution method. The preparation method is simple and convenient in operation process, reasonable in molecular weight distribution, stable in application performance, good in flexibility and excellent in tensile property, and has relatively good high temperature resistance, electrolyte resistance, cohesiveness and impact resistance. The adhesive product prepared by the invention can completely meet the high-temperature-resistant application performance requirement of the lithium battery aluminum plastic film on the inner layer adhes
