Abstract
A binder includes a polymer and ceramic particles modified with silane coupling agent. The polymer contains structural units derived from a first-type monomer, a second-type monomer, and a third-type monomer, and a molar ratio of the first-type monomer, the second-type monomer, and the third-type monomer is (50 to 58):(40 to 44):(2 to 6). The first-type monomer is selected from one or more compounds of formula I, the second-type monomer is selected from one or more compounds of formula II, and the third-type monomer is selected from one or more compounds of formula III.
