Title:
METHOD AND TOOL FOR EVALUATING AND TESTING PERFORMANCE OF INNER LAYER ADHESIVE FOR ALUMINUM-PLASTIC FILM
Document Type and Number:
WIPO Patent Application WO/2024/103812
Kind Code:
A1
Abstract:
A method and tool for evaluating and testing the performance of an inner layer adhesive for an aluminum-plastic film, relating to the field of soft packing of lithium batteries. The method comprises: preparing polyolefin window sheets and modified acid window sheets as standard samples, performing Fourier infrared analysis on the polyolefin window sheets and the modified acid window sheets in different combination modes by using a tool to obtain infrared spectrums under different grafting rates, and establishing an absorbance-grafting rate working curve according to the absorbance at predetermined wavelengths in the infrared spectrums; and separating and purifying an inner layer adhesive for an aluminum-plastic film to be tested, confirming components of a main polymer of the inner layer adhesive and the absorbance at the predetermined wavelengths by means of Fourier infrared analysis, substituting the absorbance into the working curve to obtain the grafting rates, and verifying the obtained grafting rates. The grafting rates of different types of inner layer adhesives for aluminum-plastic films can be quantitatively analyzed, the performance of main agent bodies of the inner layer adhesives for aluminum-plastic films can be reflected more truly and accurately, and transverse comparison of different types of inner layer adhesives for aluminum-plastic films is facilitated.
