Embodiment 1
[0022] A method for preparing a high temperature and scratch-resistant PI battery label material, characterized in that it comprises the following steps:
[0023] (1) Synthesis of modified polyurethane resin, the first stage is to add reactive acrylamide, 2,6-dicarboxynaphthalene, acetic anhydride, and conduct chemical crosslinking reaction with polyurethane resin at 120 ° C; the second stage is the internal addition stage , the temperature is 200°C, the stirring speed is 120 rpm, until no acid is distilled out; the high temperature resistant glue is a commercially available epoxy resin high temperature resistant glue. The mass ratio of reactive acrylamide, 2,6-dicarboxynaphthalene, acetic anhydride, and polyurethane resin is 5:5-5.5:8-10:200. In the internal addition stage, the temperature is 200° C., and the stirring speed is 120 rpm.
[0024] (2) Use a stirring device to add the isocyanate hardener into the modified polyurethane resin and stir evenly, and the proportioning...
