Hydrophobic silica is specially treated silica. It is mainly prepared by reacting general hydrophilic silica with silane coupling agent and other treatment agents under appropriate conditions according to the different characteristics of various industries to prepare a solid powdered silica grafted with polysiloxane on the surface, with a hydrophobic contact angle of 70 to 150, It not only has good hydrophobicity, but also has the functions of defoaming, thickening, leveling and anti sedimentation. It can be used in textile dyeing and finishing, defoaming agent, lubricating oil, unsaturated polyester resin, powder fire extinguishing agent, silicone rubber and other products.
