Problems solved by technology

[0003] Superabsorbent resin is mainly made of starch and acrylate, which is the most commonly used material for diapers. There are many studies on using superabsorbent resin for maternal sanitary napkins, but the composition of blood and urine is different, and the time of use is different. Replacing sanitary napkins will produce more bacteria, so it is necessary to improve the single function of superabsorbent resin, improve its bactericidal and antibacterial effect, and facilitate the use of puerpera

Abstract

The invention discloses a modified high-molecular water-absorbent resin for postpartum sanitary napkins as well as a preparation method thereof The modified high-molecular water-absorbent resin comprises the following raw materials: super absorbent resin, diatomite, ferrous sulphate, borneol, vitamin E, olive oil, an extract product of arnebia roots, beta-cyclodextrin, sodium citrate and an extract product of peach leaves. The preparation method comprises the following steps: various raw materials are weighed according to weight parts; a mixture of diatomite, ferrous sulphate, borneol, beta-cyclodextrin and sodium citrate is added into a reaction vessel, the mixture is heated to 120-180 DEG C with stirring, and the temperature is reduced to 50-60 DEG C at a speed of 10-15 DEG C / min in order to obtain a first mixture for standby; the extract product of arnebia roots and the extract product of peach leaves are added in to the first mixture with uniform stirring, plasma treatment is carried out for 3-8 seconds, the super absorbent resin is added with uniformly mixing, and after spray drying, fine powder is obtained. The modified high-molecular water-absorbent resin has the advantages of good imbibition capability and long antimicrobial time; long time usage of the product is helpful for reducing discomfort of private parts, and accelerating healing of lateral incision wounds.

Description

technical field [0001] The invention belongs to the field of maternity supplies, and in particular relates to a modified polymer water-absorbing resin for postpartum sanitary napkins and a preparation method thereof. Background technique [0002] There will be a large amount of lochia that needs to be discharged after giving birth. At this time, the uterus is in the most fragile state and is susceptible to bacterial infection and complications. Therefore, the sanitary napkins for puerpera have higher requirements, not only need to improve their swelling ability, but also need to have antibacterial and bactericidal effects. [0003] Superabsorbent resin is mainly made of starch and acrylate, which is the most commonly used material for diapers. There are many studies on using superabsorbent resin for maternal sanitary napkins, but the composition of blood and urine is different, and the time of use is different. Replacing sanitary napkins will produce more bacteria, so it ...
