Preparation method of multi-copolymerized high salt tolerant acrylic resin

Abstract

The invention discloses a preparation method of a multi-copolymerized high salt tolerant acrylic resin. Specifically, 99.98% high purity acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid, potassium carbonate, starch, and acrylamide are adopted as raw materials, ammonium peroxydisulfate and sodium bisulfate are taken as redox initiators, and N, N-methylene-bisacrylamide is employed as a crosslinking agent to synthesize the multi-copolymerized high salt tolerant acrylic resin. By adding multielement components, an advanced level of the product is achieved, and fast absorption of multi-salt components is realized. The structural strength of the product is reinforced. Manual labor is substantially reduced, automatic operation of the product is realized, and the product stability is ensured. The anti-degradation property of the product is prolonged, thus being more conducive to the health and environmental protection of consumers during use of the product.

Description

technical field [0001] The invention belongs to the technical field of highly salt-resistant absorbent resins, and in particular relates to a preparation method of multi-component copolymerized high-salt-resistant acrylic resins. Background technique [0002] The production technology of the absorbent resin in the prior art simply uses only one or two monomers, and only realizes the absorption effect of the superabsorbent resin on a pure and simple medium, and the production technology belongs to the solution polymerization method. This kind of absorbent resin in the prior art has the disadvantages of high cost, low efficiency, time-consuming, etc., and the waste caused by the product in the production process is relatively large, and complete automatic production cannot be realized. Many processes must be manually operated by a large amount of labor. The labor intensity of the workers is high and the work efficiency is low. Absorbent resins in the prior art have insufficie...

[0002] The production technology of the absorbent resin in the prior art simply uses only one or two monomers, and only realizes the absorption effect of the high-absorbent resin on a pure and simple medium, and the production process belongs to the solution polymerization method

This kind of absorbent resin in the prior art has the disadvantages of high cost, low efficiency, time-consuming, etc., and the waste caused by the product in the production process is relatively large, and complete automatic production cannot be realized. Many processes must be manually operated by a large amount of labor. The labor intensity of the workers is high and the work efficiency is low

Absorbent resins in the prior art have insufficient salt resistance, slow absorption of salt water, poor absorbency, high residual monomers in the product, and will cause a large number of human injuries to users during the use of the product, which is harmful to human health. Conducive to environmental development
