Problems solved by technology

The material is an open-cell rigid polyurethane foam material, which has problems such as low open cell ratio and limited oil absorption efficiency. In order to improve the oil absorption efficiency, the foam needs to be cut into small pieces with a volume of 0.3-1ml, which increases the work of emergency treatment. Complexity
In addition, after the material is squeezed to recover the absorbed oil, the shape of the foam block is difficult to recover and cannot be used repeatedly

Abstract

The invention relates to an oil-absorbing polyurethane foam material, which is a semi-hard polyurethane foam material with low density and high aperture ratio. The density range is 8-30kg / m3, the aperture ratio is above 90 percent, and the contact angle of the material surface and water is more than 75 degrees. The material has high oil-absorbing capability, and taking the No. 0 diesel as an example, the oil-absorbing rate of the material is higher than 35g / g. Moreover, the material not only can directly absorb oil, but also can absorb oil floating on the water surface or oil in oil-water mixture. The invention also relates to a method for emergency disposal of oil spillage and other contingencies. When the oil spillage and unexpected incident occurs, the oil-absorbing polyurethane foam material can be rapidly prepared on the accident scene to block and absorb the spilling oil at the accident source.

Description

technical field [0001] The invention relates to an oil-absorbing polyurethane foam material, in particular to a semi-rigid polyurethane foam material with low density and high porosity and super strong oil-absorbing capacity. Background technique [0002] With the increasing use and transportation of oil products, oil spill incidents of various scales have become more frequent. In recent years, the environmental pollution caused by the leakage of oil tanks in coastal and land transportation has caused great public concern. focus on. [0003] Oil-absorbing materials are an effective means to deal with emergencies such as oil spills. Traditional oil-absorbing materials are mainly divided into three categories: (1) natural inorganic oil-absorbing materials, such as silica gel, zeolite, activated carbon, bentonite, expanded graphite, FG adsorption particles, etc.; (2) synthetic organic oil-absorbing materials, such as super oil-absorbing resin, Expanded polystyrene, melt-blown...
