Abstract

The invention discloses a method for preparing polyatomic alcohol for polyurethane foam by using drainage oil or waste animal oil or plant oil or a mixture of waste animal oil and plant oil. The method comprises the following steps of: 1, treating drainage oil; 2, selecting the conventional initiator with the conventional design method for petroleum-based polyatomic alcohol, replacing 10-50 percent of the adding amount of propylene oxide or epoxy ethane in the conventional formula with the drainage oil treated in the step 1, and determining a drainage oil polyhydric alcohol formula with a method for reducing the using amount of the conventional initiator by 4-15 percent; and 3, performing oxyalkylation on a material. The method has a simple process, the problem of replacement of a petroleum resource with a renewable resource is solved, the environment can be protected, and sustainable development can be realized; and the problem that drainage oil is applied in the food industry is solved, and the health benefit of the public can be prevented from being damaged in a certain degree.
