Latest Patents

Liang's latest patents include a composition, preparation method for, and application of a self-healing composition for well cementing in oil and gas fields. This invention describes a core-shell structure where the core consists of a hydrogenated styrenic thermoplastic elastomer polymer and an inorganic filler, while the shell is made of a hydrophilic polymer. The composition exhibits a density of 1.2-2 g/cm and a water contact angle of no more than 90°. It also demonstrates an impressive diesel oil and/or natural gas absorption expansion ratio of 5-15 times. This innovative composition is designed to form a uniform and stable cement slurry, ensuring compatibility with cement mortar and providing excellent self-healing capabilities upon absorbing oil or gas.

Another notable patent involves a hydrogenated styrene/conjugated diolefin copolymer and its foaming material. This copolymer contains a styrene structure unit and a hydrogenated conjugated diolefin structure unit. The copolymer's properties include a tensile strength at break of 30-60 MPa, an elongation at break of 300-600%, and a hardness (Shore A) ranging from 70 to 98. The foaming body produced from this material exhibits remarkable performance, including over 60% rebound and less than 30% compression deformation, achieved through a supercritical carbon dioxide foaming process.
