Preparation of high-water-absorption material from sa-son seed gum graft polymeric acrylic acid (salt) by microwave radiation

Abstract

This invention refers to a kind of method of producing sopping material by grafting sand sagebrush gum into crylic acid (acrylate) in microwave radiation. The manufacturing engineering is to neutralize the crylic acid partially with sodium hydroxide, potassium hydroxide or ammonia, then adds initiator and sand sagebrush gum or other vegetable gum to it when whisking and puts it into microwave response operator after the system is well-proportioned. You should adjust it to certain radiation power and radiation time, without adding crosslinking agent to it, to graft the sand sagebrush gum into crylic acid and dry the product. After smashed, it becomes the final product. The water absorption rate of the sopping material produced by the invention is between 400ml / s and 500ml / s. The polyreaction only needs between 4min and 5min after adopting the microwave radiation technology. This invention can solve the problem of high cost of now-existing sopping material. The product can be used as anti wind erosion agent and sand-fixation agent in the field of entironment and play an active role in advancing germination, anti-drought and other dry farming.

Description

technical field [0001] The invention relates to a water-absorbing material, in particular to a water-absorbing material prepared by grafting acrylic acid (salt) with artemisia gum by microwave radiation. technical background [0002] As a brand-new energy source, microwave has gradually entered the field of chemistry, and its role in promoting chemical reactions is attracting more and more attention. The use of microwaves in synthetic chemistry began in 1986 when R.GEDGE et al. used microwaves to study esterification, hydrolysis, oxidation, nucleophilic substitution, and DIELS-ALDER cycloaddition reactions. Since then, they have made great achievements in dozens of synthetic reactions of organic compounds Great success. In addition, microwave has many applications in analytical chemistry, polymerization reaction, chemical engineering, metal ore smelting and so on. Studies in recent years have shown that microwave radiation can cause special reactions in some polysaccharide...
