Modified calcined kaolin particle with surface amphiphilicity and preparation method thereof
A method for preparing modified calcined kaolin particles with surface amphiphilicity. The method includes the steps of drying and sieving the calcined kaolin particles, adding ethanol, and stirring to obtain a suspension A, preparing an ethanol solution of a vinyl silane coupling agent, and stirring for a period of time at a certain temperature to obtain a solution B, dripping the solution B into the solution A, and stirring for a period of time at a certain temperature to obtain a suspension C, reducing the temperature of the suspension C, introducing nitrogen, adding a certain amount of sulfhydryl compound, stirring for a period of time at a certain temperature to obtain a suspension D, filtering, washing and drying to obtain the modified calcined kaolin particles.
