Description

technical field [0001] The invention relates to an ink containing titanium dioxide / calcium carbonate / silicone rubber, a porous titanium dioxide / high-temperature vulcanized silicon rubber coating and a preparation method thereof, belonging to the field of material technology. Background technique [0002] Because titanium dioxide and activated carbon fiber can produce a synergistic effect, the composite material of titanium dioxide / activated carbon fiber has a series of advantages such as high adsorption, no secondary pollution, and low energy consumption. The device needs to be simple, so it has been widely used. At present, there are two main methods for preparing titanium dioxide / activated carbon fiber composite materials. One is to soak the activated carbon fiber in the titanium dioxide Carbon precursors are mixed to form a solution, which is prepared by carbonization and activation after electrospinning. However, the titanium dioxide / activated carbon fiber composite mat...
