Abstract

The invention discloses a high oil-absorbing resin and a preparation method thereof. The high oil-absorbing resin disclosed by the invention is obtained by mixing and reacting fatty alcohol with sodium methylate or sodium ethylate to prepare fatty sodium; reacting the fatty sodium with polyvinyl chloride to prepare a comb-shaped polymer; and then performing cross-linking reaction on the comb-shaped polymer, butyl acrylate, a cross-linking agent and an initiator to obtain the high oil-absorbing resin. According to the preparation method, polyvinyl chloride and long-chain fatty alcohol are used as raw materials for synthesising the comb-shaped polymer, and the comb-shaped polymer is used as a matrix and further subjected to cross-linking polymerization with a micromolecular monomer, namely, butyl acrylate, to prepare the high oil-absorbing resin which is good in oil-absorbing performance. Simultaneously, the main raw material, namely, polyvinyl chloride, used in the preparation method disclosed by the invention is low in price, thus greatly reducing the synthesis cost.

Description

technical field [0001] The invention relates to a high oil-absorbing resin and a preparation method of the resin, belonging to the technical field of functional polymer synthetic materials. Background technique [0002] In recent years, with the rapid development of the petroleum industry, the environmental pollution caused by the leakage accidents of oil tanks and oil tankers and the discharge of industrial wastewater has attracted much attention. Therefore, it is potential to research and develop an effective oil recovery material. It must be done. Super oil-absorbing resin is a new type of functional polymer material, which is a body-shaped polymer resin with a low three-dimensional network chemical crosslinking structure. It can overcome the shortcomings of traditional oil-absorbing materials. It has the advantages of various types of oil-absorbing materials, no water absorption during oil-absorbing, small size, convenient recycling, and good oil-retaining performance. ...
