[0064] The following table explores the optimal inverse emulsion ratio from the four aspects of emulsifier type, oil-water ratio, monomer ratio, and the presence or absence of NaAA, so as to obtain the optimal anionic thermal tackifying polymer.
[0065] Table 1 Effect of emulsifier type on emulsion state
[0066]
[0067]
[0068] a × means no inverse emulsion was prepared, √ means inverse emulsion was prepared.
[0069] Table 2 Effect of oil-water ratio on emulsion state
[0070]
[0071] a × means no inverse emulsion was prepared, √ means inverse emulsion was prepared.
[0072] Table 3 Effect of monomer ratio on polymer properties
[0073]
[0074]
[0075] a × represents that the prepared polymer dry powder has no thermal viscosity-increasing property, and √ represents that the prepared polymer dry powder has thermal viscosity-increasing property.

[0081] Dissolve 31.7% (w / w, the same below) of acrylamide, 9.5% of sodium acrylate, 8.6% of F127, and 5.0% of sodium chloride in 45.2% of deionized water, adjust the pH to 7.0, and prepare water Mutually. Dissolve 14.0% emulsifier HB246 in 86.0% mineral oil, heat to 50°C to dissolve, then add the oil phase and water phase to the emulsifier in sequence according to the ratio of mass ratio oil phase:water phase=4.5:5.5, Stir well and emulsify. After the emulsification is completed, transfer it to a 250mL four-neck flask equipped with stirring, nitrogen tube, and digital display thermometer, raise the temperature to 45°C in a water bath, and after passing nitrogen for a certain period of time, add the initiator AIBN, and start the polymerization. After the thermometer shows that the temperature rise is over, keep warm for 2 hours. The inverse emulsion ETVP-P1 of the anionic heat-thickening water-soluble polymer is obtained, and the obtained inverse emulsion is precipitated, was...
