DEFOAMER EMULSION
The present invention relates to a defoamer emulsion, which comprises at least one alkyl ether sulfate or sulfonate, at least one defoamer and water, wherein the alkyl in the alkyl ether sulfate or sulfonate is C6-C22 alkyl and the average droplet diameter of the emulsion is less than 300 nm. The present invention also provides a process for producing it, a polycarboxylate ether formulation comprising the defoamer emulsion and a cement composition comprising the polycarboxylate ether formulation. The defoamer emulsion of the present invention possesses high transmittance and excellent stability. The polycarboxylate ether formulation comprising the defoamer emulsion also shows excellent stability. The cement composition comprises the polycarboxylate ether formulation according to the present invention has a low air content.
