Method for preparing high oil absorption resin

Abstract

A process for preparing the resin with high oil absorptivity from styrene and long-chain olefin monomer CnH2n, where n is equal to or greater than 4, includes such steps as preparing the low-cross-linked polystryrene or styrene copolymer, immersing it in solvent or long-chain olefin monomer or their mixture, and alkylating reaction. Its advantages are high content of gel and oil absorptivity, and low cost.

Description

a technical field

[0001] The invention relates to a preparation method of a functional polymer, in particular to a preparation method of a high oil-absorbing resin. Two background technology

[0002] Super oil-absorbing resin is a body-shaped polymer resin with a low three-dimensional network chemical crosslinking structure. Compared with traditional oil-absorbing materials, high oil-absorbing resin has many advantages such as various types of oil absorption, large oil absorption capacity, good oil-water selectivity, convenient recovery, strong oil retention capacity, no oil leakage under pressure, and easy storage and transportation, so it is widely used in Environmental protection, rubber, pesticide and paper making industries, used as various oil treatment agents, substrates, oil mist filter materials, rubber modifiers and additives for paper, etc. Oil contamination.

[0003] According to different types of monomers, super oil-absorbing resins are mainly divided into tw...
