Adsorbing material for paper diapers, preparation method and application thereof

Abstract

The invention discloses an adsorbing material for paper diapers, a preparation method and application thereof. The adsorbing material for the paper diapers is prepared from the following raw materialsin parts by weight: 100-125 parts of a polyacrylic acid high-water-absorbing resin, 45-53 parts of a poly (acrylic acid-acrylamide) high-water-absorbing resin, 30-36 parts of an acrylic acid / acrylamide / 2-acrylamide-2-methylpropanesulfonic acid ternary polymerization porous high-water-absorbing resin, 22-27 parts of graphene oxide and 8-11 parts of carboxyl carbon nanotubes. The adsorbing materialfor the paper diaper is high in urine absorbing speed, large in absorbing amount, low in back-seepage amount and firm in adsorption, can effectively reduce the urine leakage phenomenon and improve the use comfort of infants in actual use, has the effect of adsorbing irritant gases such as ammonia gas and the like, can effectively reduce peculiar smells in the using process, has a certain bacteriostatic and antibacterial effect, can inhibit the growth speed of bacteria, further reduces peculiar smells in the using process, and is high in baby use comfort in actual use.

Description

technical field [0001] The invention relates to the technical field of absorbent materials and diapers, in particular to an absorbent material for diapers and its preparation method and application. Background technique [0002] Diapers are disposable nursing hygiene products. This hygiene product is easy to use and replace, which greatly reduces the burden on nursing staff. Generally speaking, diapers can capture and absorb urine, disperse urine, or spread urine throughout the core layer, and finally absorb and store urine. Typical diapers have a waist member for securing the diaper. In order to prevent side leakage, diapers are usually added with two leak-proof folds. [0003] Among them, the quality of a diaper mainly depends on its core, which means the quality of the diaper; and the absorbent material used to prepare the absorbent core of the diaper often determines the quality of the absorbent core of the diaper. [0004] The currently used absorbent materials for d...

AI Technical Summary

Problems solved by technology

[0005] 1. The water absorption effect is poor (the water absorption rate is low), especially for urine (due to the content of sodium, potassium salt, etc. in the urine), the adsorption capacity is small, and the adsorption rate is low. Excessive urine leakage, low comfort in use;

[0006] 2. The amount of back seepage is high. After adsorption, especially after the adsorption of urine (due to the content of sodium and potassium salts in the urine), it is easy to seep back under the action of external forces, such as backlog, resulting in urine leakage. Low comfort in use;

[0007] 3. It can only adsorb water in urine, but does not have adsorption function for irritating gases such as ammonia in urine, and does not have deodorization function during use, and the use comfort is low;

[0008] 4. Does not have antibacterial and antibacterial effects, or needs to add nano-silver and other antibacterial agents, resulting in hard and heavy adsorption materials and low comfort
