Lipophilic polyurethane sponge and preparation method thereof
The invention provides lipophilic polyurethane sponge and a preparation method thereof. The lipophilic polyurethane sponge is based on porous polyurethane sponge as a matrix, and the matrix is grafted with a hydrophilic oleophobic C-C long chain group. As a way for implementation, by reaction of the polyurethane sponge and a C-C long chain-containing acyl chloride compound, so that the polyurethane sponge can be grafted with a C-C long chain by bonding of chemical bonds of amino, hydroxyl and-C (O) Cl functional groups in polyurethane. Experiments confirm that the structure can greatly reduce the surface energy of the polyurethane sponge, greatly improves the oil absorption capacity, and is low in price, non-toxic and non-pollution, so that the lipophilic polyurethane sponge is a good oil adsorption material, and can be used to quickly and efficiently adsorb and recover crude oil and other substances in crude oil leakage and other situations.
