Abstract

A non-silicon defoaming agent, includes an acrylate polymer, an organic solvent carrier, hydrophobic particles and defoaming auxiliaries; and the acrylate polymer is prepared from following raw material components: monomer-1, monomer-2, unsaturated terminated polyether, alkene, diluent and initiator. The present invention further includes a preparing method for the non-silicon defoaming agent and the application of the non-silicon defoaming agent to the defoaming and foam inhibiting in systems rich in anionic surfactants. The defoaming agent takes the acrylate polymer as the main active substance and has excellent defoaming and foam inhibiting performance. By dropwise adding monomers, the defoaming performance of the acrylate polymer is improved, by using unsaturated terminated polyether to modify, the hydrophilia of the acrylate polymer is improved, the instant defoaming capacity is further improved, and by the alkene with the carbon atoms of 6-22 to modify, the foam inhibiting performance of the defoaming agent is improved.
