摘要： A thermoplastic elastomer for profile control and water shutoff is prepared from the following raw materials in parts by weight: 8-10 parts of a component A, 1-3 parts of a strong acid, 1-3 parts of a hydrophobic modifier and 100-105 parts of water. The component A is one of polyethylene glycol, polyvinylether, polyvinyl alcohol, copolymer of acrylamide and acrylonitrile. The strong acid is one of concentrated hydrochloric acid and concentrated sulfuric acid. The hydrophobic modifier is any one of formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, β-propiolactone, γ-butyrolactone, δ-valerolactone, methyltriacetylsilane, methyltrimethylsilane, butyl acrylate and ethylene glycol dimethacrylate. The thermoplastic elastomer for profile control and water shutoff provided by the disclosure has the advantages of one-step preparation and molding, strong deformation capability, temperature resistance, salt tolerance, strong stability and the like, and is suitable for large-scale production and application.
