Method for testing coating stripping force of slurry

The invention relates to the technical field of battery slurry, in particular to a method for testing coating stripping force of slurry, which comprises the following steps: step 1, preparing a glass substrate, and then uniformly coating the glass substrate with the slurry; 2, drying the slurry coating formed in the step 1 by using a drying machine; step 3, sticking gummed paper on the slurry coating, and then rolling the gummed paper by using a pressing wheel, so that the gummed paper is firmly stuck on the slurry coating; 4, one end of the glass substrate is fixed to the lower end of a tensile machine, and the free end of the gummed paper is fixed to the upper end of the tensile machine; and step 5, starting the tensile machine to enable the gummed paper to peel off the slurry coating so as to complete the peeling force test. According to the testing method, the glass substrate is used as a standard substance for testing, so that the testing by using a foil material is avoided, and the adhesive property of
