Title:

THICKENING AGENT AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2020/253220

Kind Code:

A1

Abstract:

A thickening agent and a preparation method therefor. The thickening agent comprises HPAM and a regulator. The regulator is graphene oxide modified by an organic polymer. A structural unit of the organic polymer comprises a group having the structural formula as represented by formula (I). Due to the addition of the regulator, a high viscosity can still be maintained in a high temperature environment.
