Beschreibung
Zusammenfassung:	The invention provides a water-based insulating slurry and application thereof, the slurry comprises a resin binder, an inorganic filler, an auxiliary agent and water, the resin binder comprises a copolymer capable of being dispersed in water, the copolymer comprises a hydrophilic structure unit derived from a hydrophilic monomer and a hydrophobic structure unit derived from a hydrophobic monomer, the molar ratio of the hydrophilic structural unit in the copolymer is 10%-20%; the auxiliary agent comprises a water-soluble high-temperature hydrophobic associated polymer; the thixotropic index of the water-based insulating slurry at 100 DEG C is greater than or equal to 5, and the thixotropic index of the water-based insulating slurry at 100 DEG C is greater than the thixotropic index of the water-based insulating slurry at normal temperature. The paste is good in dispersity at normal temperature and poor in fluidity at high temperature, and when the paste is seamlessly coated with aqueous electrode active paste
