This invention belongs to the field of synthetic bio-based waterborne polyols, mainly applied to waterborne polyurethane mortar floor coatings. This invention provides a modified castor oil specifically for waterborne polyurethane mortar floor coatings. It achieves waterborne conversion and controllable functionality of castor oil through relatively simple process conditions. Emulsions made from the modified castor oil synthesized by this invention have better storage stability than emulsions made by direct external emulsification of castor oil. Furthermore, it requires less stringent process conditions than chemical grafting of functional groups to improve the hydrophilicity of castor oil, meaning that waterborne conversion and functionality control of castor oil can be achieved under milder conditions.
