Nano calcium peroxide resin matrix composite for removing formaldehyde in air and preparation method of nano calcium peroxide resin matrix composite

The invention discloses a nano calcium peroxide resin matrix composite for removing formaldehyde in air and a preparation method of the nano calcium peroxide resin matrix composite, and belongs to the field of indoor air pollution control. The nano calcium peroxide resin matrix composite comprises an oxidizing agent and a carrier, the carrier is macroporous adsorption type styrene resin SD300, the oxidizing agent is in-situ generated nanoscale CaO2 (nCaO2) on SD300, the reagent used for in-situ generation of nCaO2 comprises CaCl2, ammonia water and H2O2, and the mass ratios between resin and CaCl2, ammonia water and H2O2 are 1:(0.5-10), 1:(0.1-5) and 1:(5-15) respectively. The prepared nCaO2-SD300 composite has the advantages of large CaO2 supported quantity and difficulty in stripping off; formaldehyde can be converted into calcium formate, CO2 and H2O rapidly and enduringly at room temperature, secondary pollution is avoided, and safety is high; the composite is simple in production process, low in cost, convenient to use and wide in application range.
