A kind of antibacterial and salt-resistant superabsorbent resin and its preparation method and application

Abstract

The invention discloses an antibacterial and salt-resistant superabsorbent resin as well as a preparation method and application thereof. The preparation method of the antibacterial and salt-resistant superabsorbent resin comprises the following steps: S1, mixing acrylic acid, deionized water and lye; S2, adding a primary crosslinking agent to the acrylic lye, stirring evenly, adding Ag-SiO 2 Composite antibacterial agent intercalated graphene antibacterial composition; S3, add initiator, react for 0.5-3min, add composite fiber, obtain gel-like polymer; S4, granulate and dry the gel-like polymer; S5, combine Aromatic polyamide and nano-silver ion melt extrusion, adding ion exchange resin and composite cross-linking agent to the molten components, pressurized spraying method for thermal surface treatment of all granular polymers. The antibacterial and salt-resistant superabsorbent resin of the present invention can be used in disposable diapers, which can separate and eliminate various inorganic salt components in urine, quickly discharge moisture and heat, be dry and comfortable, inhibit bacteria, and prevent baby's red buttocks advantage.

Description

technical field [0001] The invention relates to the technical field of polymer resins, more specifically, it relates to an antibacterial, salt-resistant superabsorbent resin and its preparation method and application. Background technique [0002] Baby diapers are nursing products designed for infants and young children. This product is easy to use and replace, which reduces the burden on nursing staff. With the change of young parents' consumption concept and the accelerated pace of life, baby diapers have gradually replaced traditional diapers and become a necessity for some families to raise children. [0003] Diapers are generally composed of three main parts: the surface covering layer, the absorbent core layer and the base fabric. The absorbent core layer is mainly capable of capturing and quickly absorbing urine, dispersing urine or spreading it to the entire core layer through capillary action. The middle and final absorption and storage of urine is mainly a layered...

Problems solved by technology

[0004] Because children's urine mainly contains urea and various inorganic salt ions, such as sodium ions, chloride ions, potassium ions and sulfate ions, etc., and human urine is converted into unpleasant-tasting ammonia under the action of various microorganisms. However, the superabsorbent resin is a polymer electrolyte, and various ionic components will have the same ion effect on its water absorption process, so these components have a greater impact on the water absorption capacity of the superabsorbent resin, which is manifested as the absorption capacity of the superabsorbent resin. The liquid magnification is greatly reduced, which reduces the urine absorption performance of diapers. The diapers with reduced urine absorption capacity are prone to urine leakage, and it is difficult to quickly discharge heat and moisture, and the dryness decreases. At the same time, because the baby's skin is relatively delicate, When used for a long time, it is easy to be infected with bacteria and cause skin rashes, etc.
