Abstract

The invention discloses a high-oil-absorbency resin which is mainly prepared from the following ingredients in parts by weight: 100 parts of a acrylic monomer, 0.5-1.5 parts of a dispersing agent, 0.5-1.5 parts of an initiating agent, 3-5 parts of a chemical cross-linking agent and 4-8 parts of a physical cross-linking agent. Compared with other oil-absorbency resins prepared in a single chemical cross-linking mode in the prior art, the high-oil-absorbency resin has the advantages that oil absorption multiplying power for diesel oil is improved by 18-20%, the oil absorption multiplying power for engine oil is increased by 14-16%, the oil absorption multiplying power is remarkably increased, and the oil absorption reversibility is remarkably improved.

Description

technical field [0001] The invention relates to a resin, in particular to a high oil-absorbing resin, which can be used in environmental protection aspects such as oil recovery and water purification. Background technique [0002] In recent years, the environmental pollution caused by a large amount of oily wastewater caused by leakage accidents of oil tankers and oil tanks has attracted much attention. Traditional oil-absorbing materials cannot meet the requirements of waste oil recovery and environmental treatment in terms of performance and output. In the face of deteriorating environmental pollution, the research and development of effective oil recovery technology and oily wastewater purification materials is imperative. As a self-swelling oil-absorbing material, super oil-absorbing resin has many advantages such as various types of oil-absorbing, no water absorption during oil-absorbing, small size and convenient recycling. Oil slicks and treatment of industrial oily ...
