Abstract

See full text

A preparation method of a flexible polyurethane foam includes the following steps of: (1) subjecting an epoxidized vegetable oil, a benzoylformic acid, a basic catalyst, and an inert solvent to a ring-opening reaction in a first microchannel reactor of a microchannel reaction device to obtain a vegetable oil polyol; (2) subjecting the vegetable oil polyol obtained in the step (1), a propylene oxide and an inert solvent to an addition polymerization reaction in a second microchannel reactor of the microchannel reaction device to obtain a vegetable oil polyol for flexible polyurethane foam; and (3) using the vegetable oil polyol for flexible polyurethane foam obtained in the step (2) as the unique polyol, and subjecting the same and an isocyanate polyol to a foaming reaction to obtain the flexible polyurethane foam.
