Abstract
The present invention discloses a POSS-based hybrid supercritical COthickener and a preparation method thereof, and relates to the technical field of oil and gas field development. The preparation method of the thickener comprises the following steps: reacting tetramethyl tetravinylcyclotetrasiloxane, trimethylolpropane trimethacrylate, perfluoroacrylate and POSS containing one double bond in a molar ratio of 1-5:1-2:1-2:0.005-0.01 under the action of a catalyst to obtain the thickener. The preparation method of the POSS-based hybrid supercritical COthickener of the present invention is a bulk reaction, does not require the addition of a solvent, and does not pollute the human body and the environment in the production process. The POSS-based hybrid supercritical COthickener of the present invention has a high thickening efficiency on supercritical carbon dioxide and can better increase the viscosity of the supercritical carbon dioxide, so that the carrying and supporting effects of the supercritical carbon dioxide are improved.
