| 摘要 |
The present invention relates to self-emulsible non-silicon defoamer composition having a great foam breaking effect by a small amount due to foam breaking properties and defoamation continuity, used in various latex emulsification processes and defoamation of general paints, aqueous foaming solution, etc. by having excellent dilution stability and storage stability from high affinity by uniformly dispersing silica, oil, and a surfactant, and having improved defoaming performance even under neutral, acid, and alkali environments. The self-emulsible non-silicon defoamer composition comprises liquid paraffin, a polyoxyethylene polyoxypropylene block copolymer, a polyoxyethylene dialkyl esters polymer, a polyoxyethylene polyoxypropylene dialkyl ester polymer, a polyoxyethylene alkyl ether compound, a fine powder of silica, at least two kinds of a lubricant component, and sodium carboxymethyl cellulose as a water-soluble dispersion stabilizer. |
