Problems solved by technology

However, with the rapid development of science and technology and economy today, environmental pollution is becoming more and more serious, such as the leakage of crude oil from oil tankers at sea, the cleaning of oil tanker cargo tanks and the petroleum products entering the ocean, and the leakage of offshore oil wells and pipelines, etc., causing large-scale sea surface pollution. Marine life and resources are seriously threatened, which not only causes the deterioration of the ecological environment, but also affects the economic activities of coastal residents
Ordinary materials have small oil absorption, poor oil retention rate, oil absorption and water absorption, and are not suitable for handling oil slicks and oil spill accidents at sea

Abstract

The invention discloses high oil absorbing resin and a preparation method thereof, the main raw materials are as follows: 100 parts of monomer, 5-30 parts of an emulsifier, 10-30 parts of a crosslinking agent, 1-3 parts of an oxidation agent, 1-4 parts of a reducing agent and 500-900 parts of deionized water. The preparation method is as follows: adding the emulsifier and the crosslinking agent into the monomer, stirring evenly, introducing nitrogen, adding deionized water dropwise, after the deionized water is added completely dropwise, obtaining emulsion, adding an initiating agent into the obtained emulsion, reacting for 4 h, and drying the product in vacuum to obtain the oil absorbing resin with high oil absorption rate. The advantages of the high oil absorbing resin are as follows: the high oil absorbing resin has large porosity, and can be reused for 4-8 times. The oil absorbing resin has the advantages of mild reaction, simple preparation method and low cost.

Description

[0001] technical field [0002] The invention relates to a preparation method of oil-absorbing resin. Background technique [0003] For a long time, environmental issues have been the focus of attention all over the world. It is the consensus of people all over the world to take the road of sustainable development and improve the ecological environment of the earth. However, with the rapid development of science and technology and economy today, environmental pollution is becoming more and more serious, such as the leakage of crude oil from oil tankers at sea, the cleaning of oil tanker cargo tanks and the petroleum products entering the ocean, and the leakage of offshore oil wells and pipelines, etc., causing large-scale sea surface pollution. Marine organisms and resources are seriously threatened, which not only causes the deterioration of the ecological environment, but also affects the economic activities of coastal residents. Ordinary materials have small oil abso...
