Data for: Preparation and performance evaluation of latex

To prevent considerable foaming of the latex cement slurry, soap-free emulsion polymerization was employed to prepare latex, which did not require a stabilizer to achieve good stability of the latex. In addition, effects of the AMPS addition, monomer ratio, synthesis temperature, and stirring speed on the performance of the latex were investigated by using AMPS, styrene, and butyl acrylate as the reaction monomers, and the latex was characterized by infrared spectroscopy and TEM.
The stability of latex was significantly affected by AMPS addition, with good stability at an AMPS content of greater than 30%. With the increase in the addition amount of AMPS, the fluid loss of the cement slurry decreased and then increased; it was the lowest at 40% AMPS, with a loss of 27.32 mL. The analysis suggested that this result may be attributed to the effect of the AMPS addition on the particle size of the latex, resulting in a change in the fluid loss of the cement slurry.
With the increase in the m..., There are three main method types:
(1) Latex particle size test: First, latex and deionized water were evenly mixed at a mass ratio of 1:50, and the mixed liquid was absorbed using a rubber dropper into the sample tube, and the top cover of the sample tube was covered. The particle size was analyzed by using a Brookhaven Zeta Potential and Laser Particle Size Analyzer 90Plus Zeta instrument. Each sample was tested in triplicate, and the average value was taken as the particle size of the sample.
(2) Fluid loss test of cement slurry: The cement slurry was prepared using a waring blender according to the American Petroleum Institute (API) standards. First, latex was added to water, followed by the addition of the class G oil well cement and mixing using a constant speed mixer at a low speed for 15 s and then at high speed for 35 s. Second, the mixed cement slurry was poured into a cement slurry filter press and sealed, and the pressure was set to 6.9 MPa. The fluid loss over 30 min was ob..., Please see the README document (\"README_Dataset-Preparation and Performance Evaluation of Latex.txt\").
