preparation example Construction

[0023] For this reason, the invention provides a kind of preparation method of polyacrylate super oil-absorbing resin, comprises the steps:

[0024] a. The dispersant is completely dissolved in the dispersed phase;

[0025] b. Mix the long and short chain alkyl acrylate monomers and acrylate monomers, and add them to the belt together with the initiator, crosslinking agent, porogen, dispersant and dispersant solution in step a. In a reaction vessel with a stirrer, a thermometer, and a condenser;

[0026] c. If an elastomer with oil absorption capacity is added, a certain amount of elastomer is added to the toluene solution in advance to make it swell until dissolved, and the addition method is the same as other components in step b.;

[0027] d. Under the protection of nitrogen, raise the temperature of the mixed system to 30~40°C, stir until the mixture is uniform, then raise the temperature to 70°C for 4 hours, raise the temperature to 80°C for 2 hours, and finally raise th...

Abstract

The invention discloses high-performance oil-absorbing polyacrylate resin and a preparation method thereof. Through adoption of common alkyl acrylate and acrylate monomers, through optimization of the monomer composition, improvement on the monomer ratio and introduction of an ethylene-propylene-diene monomer rubber structural agent, and through suspension polymerization, particle-like high-performance oil-absorbing resin having a good surface morphology and free of surface adhesion is prepared. The resin has good oil-absorbing performance, the oil absorption multiple, the oil absorption speed rate and the oil retention rate thereof are obviously superior to those of ordinary oil-absorbing resin materials in the market, and defects of the conventional oil-absorbing materials are overcome, so that the resin has a good application prospect in the fields of petrochemical industry, military affairs, environmental treatment and the like.

Description

technical field [0001] The invention relates to petrochemical, environment and military fields, in particular to an oil-absorbing resin, more precisely a polyacrylate super oil-absorbing resin and a preparation method thereof. Background technique [0002] With the continuous development of industrial technology, the offshore oil industry has increasingly highlighted its important position, but at the same time, it has also brought a series of environmental problems, such as frequent oil spill accidents, industrial wastewater discharge into the sea, oil tanker leakage, etc., not only It has brought great damage to marine ecology and human living environment, and also caused limited resources to be wasted. Therefore, the research and development of high-quality oil-absorbing resin materials has become a major issue at this stage. [0003] At present, the super oil-absorbing resins developed at home and abroad generally include four categories, namely, acrylate super oil-abso...
