| titleOfInvention | A kind of oil-well cement high efficiency composition defoaming agent and preparation method thereof |
| abstract | The invention discloses a kind of oil-well cement high efficiency composition defoaming agents and preparation method thereof, for the defoaming during puddling containing the cementing slurry high speed shear there are many additive, foam inhibition.It is calculated in mass percent, auxiliary components is defoamed by 15-59.5% mineral oil, 40-84.5% polyol fatty acid ester, 0-15% alicyclic polybasic acid fatty alcohol and 0.5-15%, the defoaming auxiliary components include polyethers, three iso-butyl ester of phosphoric acid one or two.The defoaming agent is the preparation method is as follows: under stirring at room temperature, mineral oil is successively added into batching kettle, polyol fatty acid ester, alicyclic polybasic acid fatty alcohol and defoaming auxiliary components are stirred 0.5-2.0 hours, filtering and discharging, metering packing.Defoaming agent of the invention is low in cost compared to common oil-well cement defoaming agent, manufacture craft is simple, and product stable homogeneous has both defoaming, foam inhibition function, does not influence cement paste rheological, the thickening performances such as performance and Behavior of Hardened Cement Paste compression strength. |
