Problems solved by technology

This oil-absorbing material has obvious disadvantages such as small oil absorption ratio, poor oil-water selectivity and oil retention.
The second oil-absorbing material is to use synthetic hydrophobic materials such as polyethylene, polypropylene, polyethylene terephthalate and other fibers to prepare non-woven fabrics and mesh felts with certain physical shapes. Improved performance, but poor oil retention
Most of the free radical polymerization methods used are suspension polymerization and a small number of emulsion polymerization. The two polymerization method systems need to add water-soluble macromolecular compounds and surfactants respectively, and the coagulation phenomenon that is difficult to control in suspension polymerization, etc., resulting in Problems in the purity, performance, application range and production process of synthetic resin are difficult to control

Abstract

The invention relates to acrylate polymer high oil absorption resin and a preparation method and application thereof. The oil absorption resin comprises the following components in part by weight: 50 to 95 parts of flexible chain segment monomer, 5 to 50 parts of rigid chain segment monomer, a cross-linking agent in an amount which is 0.2 to 5 percent of the total weight of the monomers, and a solvent in an amount which is 1.5 to 4 times the total weight of the monomers. The high oil absorption resin is prepared by free radical solution polymerization at room temperature under the initiation of gamma rays. The preparation process is simple, the reaction condition is easy to control, energy consumption is saved, and the method is safe and environmental-friendly and is more suitable for industrial production. The prepared high oil absorption resin has the advantages of high purity, complete hydrophobicity, wide application range, capacity of absorbing multiple types of oil, high oil absorption multiplying power, high oil retention performance, recyclability and the like, and can be widely applied to the absorption of floating oil on the sea surface, scattered oil, cooled emulsified oil on lathes of factories, and oil and organic substances in industrial production and domestic sewage.

Description

technical field [0001] The invention relates to an oil-absorbing material and its preparation method and use, in particular to an acrylate polymer super oil-absorbing resin and its preparation method and use. Background technique [0002] High Oil-Absorbable Resin (HOAR for short) is a polymer with a moderately cross-linked three-dimensional network structure. Its oil-absorbing driving force is the mutual affinity between the lipophilic group of the resin and the oil molecule. The oil-absorbing process is The swelling and stretching process of the cross-linked three-dimensional network structure. This kind of resin has the advantages of strong oil absorption capacity and good oil retention performance, and can be used for the treatment of various oil pollution systems. As an environmentally friendly material, it is widely used in industry, agriculture, daily life and other fields. [0003] The progress of oil-absorbing materials can be divided into three types in terms of ...
