Problems solved by technology

Due to the characteristics of light weight and easy diffusion of leaked fuel oil, engine oil and other oil stains, it is difficult to effectively remove them by ordinary fence recycling methods
It is a more effective way to use hydrophobically modified light particles to absorb and recover floating oil, but the inorganic light particles that can float are usually closed-cell structures that are hollow inside but smooth on the surface, and their hydrophobicity and specific surface area are limited. , resulting in insufficient oil slick adsorption capacity

Abstract

The invention discloses a method for preparing light floating particles which are loaded with hollow inorganic particles on the surfaces and used for scavenging water surface floating oil. The inorganic light particles are taken as carriers, polystyrene is taken as an intermediate substance, polystyrene / titanium dioxide composite particles are synthesized on the surfaces of the light inorganic particles in a modification manner, polystyrene is removed by roasting, and inorganic carrier / hollow titanium dioxide composite particles are obtained. Titanium dioxide microspheres are stacked densely in a multi-layer manner on the surfaces of the carriers, larger cavities are formed inside the microspheres, and the microspheres have higher oil fouling bearing capacity. After surface oleophylic modification, the floating oil scavenging agent can actively absorb the floating oil on the water surface, the particles absorbing oil gather into a cluster, and fishing is convenient. Because the carrier particles and the hollow titanium dioxide all have acid-base resistance and high temperature resistance, the scavenging agent is suitable for the use in different oil fouling leakage environments; the particles which absorb oil and are recycled can be reused through simple roasting treatment.

Description

technical field [0001] The invention relates to a preparation method of a water surface oil slick scavenger, in particular to a preparation method of a scavenger which has a large specific surface area and can effectively remove water surface leaked oil slicks. Background technique [0002] With the development of the water transportation industry, the environmental pollution caused by fuel oil leakage has attracted more and more attention. Due to the characteristics of light weight and easy diffusion of leaked fuel oil and engine oil, it is difficult to effectively remove them by ordinary fence recycling methods. It is a more effective way to use hydrophobically modified light particles to absorb and recover floating oil, but the inorganic light particles that can float are usually closed-cell structures that are hollow inside but smooth on the surface, and their hydrophobicity and specific surface area are limited. , resulting in insufficient oil slick adsorption capacity...
