Preparation of Oil Absorption Bubbles Using a New Surface Treatment Technology

We used surface treatment technology to handle wasted polyurethane foam in this paper. And made out a series of new oil absorbed foams to realize the waste reused. We used the following two technical schemes to improve oil absorption of the polyurethane foam: 1 Dealing polyurethane foam with tung oil;2 Dealing polyurethane foam with tung oil and organic silicon compoundly. Study shows the oil absorbency is up to 22.4 times when using tung oil, at the same time when the concentration of organic silicon is 1:5 , the oil absorbency is 16 times. The oil absorption effect of polyurethane soft foam which experiences the twenty-minute tung oil processing is the best.
