Abstract

The invention discloses super absorbent resin containing boron and a preparing method thereof.The method comprises the steps that 1, starch paste containing boron is prepared; 2, acrylic acid is neutralized with strong base; 3, graft copolymerization between starch and acrylic acid is conducted under the catalysis and induction of bio-enzyme; 4, graft copolymerization products obtained in the step 3 are dried and smashed, so that the super absorbent resin containing boron is obtained.The starch graft copolymerization acrylic acid super absorbent resin is prepared with bio-enzyme as a catalyst and initiator, and the preparing process has the advantages that reaction conditions are mild, and the reaction process is easy to control and environment-friendly.The prepared super absorbent resin has the advantages of being high in starch grafting rate, water absorption rate, biodegradability and the like.Furthermore, due to the fact that the super absorbent resin contains boron, the problem that plants grown in mountain land, river shoal sandy land or gravel land soil where boron and salt is lost easily can not fruit can be well solved.

Description

technical field [0001] The invention relates to the field of biological enzyme catalysis and functional polymer materials, in particular to a superabsorbent resin containing boron and a preparation method thereof. More specifically, it relates to a boron-containing superabsorbent resin prepared by using a biological enzyme as a catalytic initiator and a preparation method thereof. Background technique [0002] Superabsorbent resin is a kind of functional polymer with strong hydrophilic functional groups such as carboxyl group and hydroxyl group, and has a spatial network structure. Through hydration, it can quickly absorb water dozens or even thousands of times its own weight, and it can also absorb liquids such as saline, blood, and urine dozens to a hundred times. As a new type of functional polymer material, superabsorbent resin has the characteristics of large water absorption and strong water retention. It is completely different from traditional water-absorbing materi...
