Document Type and Number:
WIPO Patent Application WO/2022/226863
Kind Code:
A1
Abstract:
The embodiments of the present invention provide a method for preparing, by using an oil sand tailing raw material, a composite pigment and filler for a coating. The method comprises: subjecting an oil sand tailing raw material to a heat treatment, wherein the heat treatment comprises drying the oil sand tailing raw material and calcining the oil sand tailing raw material, such that on the surface of the oil sand tailing raw material, asphalt wraps particles of an oil sand tailing and is carbonized; performing coarse crushing on the heat-treated oil sand tailing; and performing superfine processing on a mixture of the coarse-crushed oil sand tailing and a toner, such that the superfine-processed oil sand tailing is used as the composite pigment and filler.
