Title:
FUNCTIONAL FILM, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/067581
Kind Code:
A1
Abstract:
Disclosed are a functional film for enhancing the bonding strength of a polymer film and an asphalt rubber material and a preparation method therefor. The functional film comprises a polymer film layer and a performance improvement layer coating at least one surface of the polymer film layer. The performance improvement layer comprises an adhesive layer serving as an inner layer and a passivation layer serving as an outer layer. The adhesive layer is formed by uniformly coating with a first polymer emulsion. The passivation layer is formed by uniformly coating with a passivation emulsion. The passivation emulsion is obtained by mixing a second polymer emulsion, a filler and water. The numbers of layers of the adhesive layer and the passivation layer are not 0 at the same time. According to the present invention, the performance improvement layer is arranged on a carrier layer, and by means of the bonding strength of the performance improvement layer and the polymer film layer and the good bonding force of the performance improvement layer and an asphalt rubber material layer, the low-temperature peel strength of the polymer film layer and the asphalt rubber material layer is effectively improved, and the problem that the bonding performance of an existing polymer film and an asphalt rubber material layer is obviously reduced in a low-temperature environment is solved.
