High molecular absorption polymer, preparation method and use thereof

Abstract

The invention provides a polymer absorbent polymer, a preparation method and its application, and belongs to the field of material technology. The preparation method includes: providing a diatomite / sodium carboxymethyl cellulose superabsorbent resin; Carboxymethyl chitosan / polyaspartic acid hydrogel, the cross-linking agent includes hydrazine hydrate, aspartic acid and diethylaminoethanol; then the superabsorbent resin and hydrogel are homogenized under a pressure of more than 200bar , that is, a three-dimensional network-like polymer absorption polymer. The above preparation method can improve the water absorption and water retention performance, increase the antibacterial and antibacterial effect, enrich the diversity of channels in the polymer structure, enhance the air permeability, dehumidify and have no peculiar smell, improve the water absorption rate and water absorption and water retention capacity, and reduce the slippage and liquid penetration time, improve fluid-conducting performance and skin-friendly comfort, prevent skin inflammation, and be biodegradable, environmentally friendly and non-polluting; the use of the prepared polymer in the preparation of fluid-absorbent cores or fluid-absorbent products.

Description

technical field [0001] The invention belongs to the technical field of materials, and specifically relates to a polymer absorption polymer, a preparation method and an application thereof. Background technique [0002] With the improvement of people's living standards, people have higher requirements for the quality of life needs. Absorbent articles used for personal hygiene are designed to absorb and contain bodily exudates, in particular large quantities of urine, body fluids and the like. These absorbent articles comprise multiple layers serving different functions, such as a wearer-facing liquid-permeable topsheet, a garment-facing liquid-impermeable backsheet with an absorbent core in between and other layers. The function of the absorbent core is generally to absorb and hold exudates for an extended amount of time, minimizing rewet to keep the wearer dry and avoid soiling clothing or linens. [0003] Since absorbent products are in direct contact with human skin, the...

AI Technical Summary

Problems solved by technology

[0003] Since the absorbent product is in direct contact with the human skin, the environment in urine or body fluid is suitable for the growth and reproduction of bacteria. The bacteria will be adsorbed on the surface of the absorbent product and then adhere to the skin, resulting in the continuous reproduction and accumulation of bacteria, which is easy to cause discomfort and infection

For example, diapers can only meet the basic absorption function and have no effect on skin protection. When users use diapers, the air permeability is not good, the moisture in the hygroscopic layer is easy to reverse osmosis, and the urine contains toxins, especially the delicate skin of babies Therefore, it is easy to be infected with bacteria, causing skin inflammation such as diaper rash

[0004] Superabsorbent resin SAP is a low-density cross-linked functional polymer material with good water absorption and water retention properties. It has been applied in human physiological hygiene, medical treatment, etc. Salt water has the disadvantages of slow water rate and poor water retention
