摘      要：Surface modification of wollastonite particles using titanate as a modification agent incorporated by simultaneous wet ultra-fine grinding in a laboratory stirred mill was *** physical,physic-chemical and application properties of the modified wollastonite were measured and *** results showed that grinding intensity markedly influences the modification effect because of the mechano chemical *** hydrophilic surface of wollastonite was turned into a hydrophobic one after *** interaction between titanate and wollastonite under wet grinding circumstances was *** was suggested that physical adsorption and chemical adsorption of titanate coexisted on the wollastonite *** mechanical properties of polyethylene（PE） filled with the modified wollastonite powder were markedly improved.
