| description | The present disclosure relates to the field of lithium-ion batteries, and specifically relates to a high temperature resistant adhesive for a ceramic diaphragm of a lithium battery and to a preparation method therefor. The present disclosure further relates to a lithium battery diaphragm comprising the high temperature resistant adhesive. The adhesive is a latex acrylic polymer resin having an interpenetrating network structure, and the adhesive polymer has a glass transition temperature greater than 160°C; the ratio of the thermal shrinkage rate of the lithium battery diaphragm prepared from the high temperature resistant adhesive at 150°C, relative to the heat shrinkage measured at 120°C, is less than 2; there is a relatively small change in the thermal shrinkage rate of the diaphragm even with a steep increase in temperature, thus satisfying requirements for manufacturing a ceramic diaphragm having high safety performance; moreover, the present adhesive is a water-based adhesive, does not contain an organi |
