Composite emulsion type lithium battery ceramic diaphragm adhesive as well as preparation method and application thereof

The invention relates to the field of lithium battery ceramic diaphragm adhesives, and discloses a composite emulsion type lithium battery ceramic diaphragm adhesive as well as a preparation method and application thereof. Water-soluble and water-insoluble monomers, a reactive emulsifier, an initiator and the like are added in batches for polymerization to obtain a composite system product of a conventional emulsion and a microemulsion, and the particle size distribution of the composite system product has the characteristic of bimodal distribution and is respectively within the range of less than 100nm and the range of 100nm-1000nm. Reaction raw materials comprise the following components: 5-15 parts of a water-soluble monomer; 10 to 30 parts of a non-water-soluble monomer; 0.5-2 parts of a reactive emulsifier; 0.1 to 0.5 part of a co-emulsifier; 0.2 to 1 part of an initiator; and 70 to 80 parts of pure water. The preparation process of the product is simple in technology and low in energy consumption. The a
