More Information
Summary:The invention relates to the technical field of filter material surface treatment, and discloses a surface modifier for a filter material as well as a preparation method and application thereof; the surface modifier for the filter material comprises a resin emulsion, a first dispersing agent and a microcapsule curing agent dispersed in the resin emulsion, wherein the microcapsule curing agent comprises a second dispersing agent, a core material curing agent and a microcapsule wall material wrapping the core material curing agent, the mass ratio of the second dispersing agent to the core material curing agent is (0.1-20): 1, and the solid content of the resin emulsion is 1-20%. The microcapsule curing agent coated with the core material curing agent is uniformly dispersed in the emulsion and has good stability. The core material curing agent is isolated from the resin emulsion, so that the core material curing agent is prevented from being in contact with the resin emulsion; therefore, the storage stability of
