Abstract

The invention discloses an environment-friendly nanometer formaldehyde purification scavenger which comprises the following components in percentage by weight: 1-3 percent of natural plant extract, 15-30 percent of nanometer TIO2 sol, 1-3 percent of sodium dodecyl benzene sulfonate and the balance of deionized water. The natural plant extract is amino acids which are extracted from powder mixture of more than two of tea, aloe, chlorophytum comosum and hedera helix through a supercritical method. The natural plants are used in the components of the environment-friendly nanometer formaldehyde purification scavenger; therefore, the percentage of other chemical materials is correspondingly reduced and secondary pollution caused by the air purifying agent can be reduced. The environment-friendly nanometer formaldehyde purification scavenger has strong absorption, good purifying effect and high clearance rate for harmful gas such as benzene series substances with weak polarity or non-polarity. When the environment-friendly nanometer formaldehyde purification scavenger is prepared, the production process is simple, and the production cost is low.
