[0040] A preparation method of composite air purifier, comprising the following steps:
[0041] 1) Preparation of component I: take a non-polar carrier, add it to the active component A solution, soak and filter to obtain a carrier loaded with active component A; let the carrier loaded with active component A stand until there is no liquid drop out, then dry and cool naturally to obtain component I;
[0042] 2) Preparation of component II: take the polar carrier, add it to the solution D containing the active component B and the accelerator C, and after impregnating and filtering, obtain the carrier loaded with the active component B and the accelerator C; The carrier of Component B and Accelerator C is allowed to stand until no liquid drips out, and after drying and natural cooling, Component II is obtained;
[0043] 3) Compounding: According to the proportioning ratio of the formula, component I and component II are evenly mixed in a certain proportion to obtain the composi...
