Abstract

The invention discloses polymer water-absorbent resin for diapers and a preparation method thereof. The polymer water-absorbent resin for diapers comprises the following raw materials: bisphenol A type polysulfone resin, polycarbonate, polylactic acid, bamboo charcoal fiber, carbon nano-tube, silane coupling agent KH-560, acrylic acid, N,N-methylene bisacrylamide, potassium persulfate, sodium sulfite, methylene succinic acid, sodium hydroxide, kelp, acrylamide, a modified antibacterial auxiliary agent and a toughening modification auxiliary agent. The polymer water-absorbent resin for diapersis prepared by the steps of preparing a base material, preparing a modified material, and then mixing the base material and modified material. The polymer water-absorbent resin for diapers, provided by the invention, has excellent antibacterial and toughness properties.

Description

【Technical field】 [0001] The invention belongs to the technical field of resin preparation, and in particular relates to a polymer water-absorbing resin for diapers and a preparation method thereof. 【Background technique】 [0002] With the development of the economy and the acceleration of the pace of life, diapers have become one of the baby care products loved by young mothers. "Diapers" work with a layered absorbent core made of pure wood pulp and super absorbent resin. There are many types of water-absorbing polymer materials for existing diapers, but their liquid absorption speed is slow, their antibacterial and antibacterial effects are poor, their air permeability is not good, their skin affinity is not enough, and they are easily damaged due to poor toughness. [0003] Chinese patent application document "A polymer water-absorbent resin for diapers and its preparation method (application publication number: CN107586363A)" discloses a polymer water-absorbent resin fo...
