Background
In recent years, offshore oil leakage frequently occurs, the harm of oil pollution is not small, and how to effectively treat oil spill pollution is a global problem. Methods for treating petroleum pollution are classified into chemical methods and physical methods. Among them, the chemical method, which is a method of treating by using a dispersant and direct combustion, is simple and fast in treatment speed, but generates a large amount of chemical residues. In contrast, the physical recovery adsorbs and stores the spilled oil on the sea by means of the oil absorption material or the separator, so that not only can pollution be effectively cleaned, but also the substances after oil absorption are easy to recover, and the method is an ideal spilled oil treatment method.
The polypropylene spunbonded nonwoven material and the polypropylene melt-blown nonwoven material are widely used chemical synthesis oil absorption materials at present, and have hydrophobicity and lipophilicity, and can be suspended on water surface after absorbing oil, so the polypropylene spunbonded nonwoven material and the polypropylene melt-blown nonwoven material are widely applied to recovery of floating oil on the water surface. However, most of the currently used oil absorption materials have single structure and low oil holding rate, and are easy to leak oil to cause secondary pollution when being extruded by external force in the using process.

The present invention is also characterized in that,
the oil absorption layer and the oil storage layer are combined together through needling reinforcement, and the kapok sandwich layer and the impermeable layer are uniformly point-bonded by spraying 5% polyvinyl alcohol solution.
The gram weight of the oil absorption layer is 140g/m2The needling density is 40 punches/cm2The gram weight of the oil reservoir is 100g/m2The gram weight of the barrier layer is 40g/m2。
The composite reinforcing needling density of the oil absorption layer and the oil storage layer is 50-75 spines/cm2Or 115 to 150 thorn/cm2。
