Glass fiber coated filter material with catalytic function and preparation method thereof

The invention discloses a glass fiber coated filter material with a catalytic function and a preparation method thereof. The glass fiber coated filter material consists of a glass fiber filter material base material, a glass fiber protective film, a catalyst nano-particle layer and an expanded microporous polytetrafluoroethylene filter film. During application in filtering, dust is firstly blockedby the expanded microporous polytetrafluoroethylene filter film of the glass fiber coated filter material with the catalytic function, so that the active sites on catalyst nano-particles are prevented from being covered with the dust and thus losing activity, the catalytic function of the catalyst is efficient and can last for a long time, and residual harmful gas is decomposed by the catalyst nano-particle layer to achieve the purpose of comprehensive prevention and control of the dust and harmful gas. The integration of dust removal, desulfurization, denitration, dioxin removal, mercury removal and the like is achi
