Description

【Technical field】 [0001] The invention belongs to the field of baby products, and in particular relates to a water-locking antibacterial material for diapers and a preparation method thereof. 【Background technique】 [0002] The working substance of "diapers" is a functional polymer material with strong water absorption capacity. The material it uses is super absorbent resin. In the late 1960s, the United States first successfully developed super absorbent resin. This is a polymer material that contains strong hydrophilic groups and usually has a certain degree of crosslinking. It is insoluble in water and organic solvents, and its water absorption capacity can reach 500-2000 times its own weight, up to 5000 times. After absorbing water, it immediately swells into hydrogel, has excellent water retention, and is not easy to squeeze out even under pressure. After the water-absorbed resin is dried, the water-absorbing ability can still be restored. Structural characteristics...
