HUMIDITY-RESISTANT SELF-SUSPENDING PROPPANTS |
摘要 |
A dry self-suspending proppant comprises a proppant particle substrate and a coating on the proppant particle substrate. The coating is made from a hydrogel-forming polymer and a polyol or polyamine which have been crosslinked together by means of a covalent crosslinking agent. |

1. A dry self-suspending proppant comprising a proppant particle substrate and a coating on the proppant particle substrate, wherein the coating comprises the reaction product obtained when a hydrogel-forming polymer is crosslinked by means of a covalent crosslinking agent in the presence of an organofunctional compound comprising one or more polyols, one or more polyamines or a mixture thereof, wherein the covalent crosslinking agent is also capable of reacting with the organofunctional compound. |
