High oil absorption resin and synthetic method thereof

Abstract

The invention discloses a high oil absorbing resin, and a process for preparation comprises utilizing short-chain ester of (metyl group) acrylic acid, long-chain ester of acrylic acid and styrene monomer to be monomers, adding dispersing agent and surface active agent, and getting through suspension polymerization and random copolymerization under the condition of the existence of cross linker and initiating agent. The process for synthesizing has lithe time consumption, which can be industrialized, and high oil absorbing resin which is got has high oil absorbing efficiency, fast oil absorbing speed, and which can be recycled to be repeatedly used.

Description

technical field The invention relates to a functional polymer synthetic material, in particular to a high oil-absorbing resin and a synthesis method thereof. Background technique With the development of my country's chemical industry, the environmental pollution caused by oily sewage, waste liquid and industrial accidents such as oil tanker leakage is becoming more and more serious. In organic wastewater, benzene, toluene and halogenated hydrocarbons are more harmful to the environment, and These substances are difficult to degrade and are difficult to deal with by conventional physical and biological methods. For these oily pollutants, it is more effective to use oil-absorbing materials for oil-water separation to achieve centralized treatment of oily pollutants. Among the existing oil-absorbing materials, those with large specific surface area and porosity were developed earlier, including bentonite, feathers, animal hair, and some synthetic fibers. This kind of oil-abso...

Problems solved by technology

Due to the low polymerization activity and high price of long-chain acrylate esters, the research on polyacrylic acid long-chain ester oil-absorbing resins mostly stays in the laboratory research stage, and there is no report on industrial application.

The oil-absorbing resin synthesized by medium-chain acrylic acid ester or short-chain acrylic acid ester has a high oil-absorbing ratio, but the oil-absorbing rate is very slow, and it often takes several hours to reach saturated oil-absorbing, and this kind of oil-absorbing resin is prone to loss of strength after oil-absorbing Significantly decreased, adhesion between the resins, so the resin can not be reused
