The invention relates to hydrophobing additives on the basis of silica, one or more silicone resins and one or more functionalized alkylalkoxysilanes, the alkyl groups thereof carrying at least one amino, carboxylic acid, epoxy or hydroxy group.

Functionalized graphene is provided. The functionalized graphene is graphene onto whose surface one or more active molecules are grafted, the active molecule includes a plurality of terminal functional groups, and the plurality of terminal functional groups include at least two active functional groups. Because the active functional groups can chemically react with molecules in silicone oil, the functionalized graphene can evenly dissolve in the silicone oil, so that polyorganosiloxane prepared by using the functionalized graphene has good heat conduction performance. In addition, this application further provides a preparation method of the functionalized graphene and corresponding polyorganosiloxane.

The present disclosure relates to a method for preparation of a high temperature-resistant bismuth yellow pigment. The method comprises: mixing an oxide which served as a matrix and dopan with a bismuth source, a vanadium source, or a molybdenum source, and then placing the mixture into a mill for grinding to obtain a precursor; further calcining and crushing the precursor to obtain the high temperature-resistant bismuth yellow pigment powder. The bismuth yellow pigment has a bright color, a b* value greater than 90, a stable performance, and a high heat-resistance above 800? C. The method is environmentally friendly without waste, and reaction conditions are simple. Doping of BiVO.sub.4 crystal lattices by incorporation of oxides can be achieved, so that the particle size and distribution of the bismuth yellow pigment can be effectively controlled while the color performance of the bismuth yellow pigment is greatly improved.
