Water-absorbing high polymer material for baby diapers and preparation method thereof

Abstract

The invention discloses a water-absorbing high polymer material for baby diapers and a preparation method thereof. The material comprises the following raw materials: lithospermum, aloe, purslane, sericin, silkworm pupa amino acid, calcium chloride, magnesium sulfate, polypropanol, polyacrylamide, ethyl acetate, carbon fiber, bamboo fiber, acrylic acid, petroleum ether, sodium persulfate and paraffin. The method includes: melting paraffin, adding carbon fiber and bamboo fiber, performing low temperature refrigeration and freeze-drying, and carrying out grinding to obtain first mixture powder; mixing propyl alcohol, polyacrylamide, ethyl acetate, acrylic acid and sodium persulfate, conducting heating dissolving, performing plasma treatment, then adding the first mixture powder, calcium chloride, magnesium sulfate and petroleum ether to conduct further stirring, and conducting spray drying so as to obtain a second mixture; subjecting lithospermum, aloe and purslane to mixed decoction, performing filtration, and merging the filtrate, then adding sericin and silkworm pupa amino acid, and performing spray drying to obtain a third mixture; and mixing the second mixture and the third mixture, performing microwave treatment, then adding the mixture into a double-screw extruder, and performing extrusion. The material provided by the invention has the advantages of strong water absorbing capacity and good bactericidal effect.

Description

technical field [0001] The invention relates to the field of baby products, in particular to a water-absorbing polymer material for diapers and a preparation method thereof. Background technique [0002] The water absorption mechanism of water-absorbent resin is as follows: when the resin is absorbing water, the long polymer chains are entangled with each other and cross-linked to form a network structure. The polymer network is a solid network bundle. When the polymer meets water, the hydrophilic groups With the hydration of water molecules, the carboxylic acid groups are ionized, resulting in a difference in ion concentration inside and outside the network, and osmotic pressure inside and outside the cross-linked network. Water molecules are continuously drawn into the crosslinked network through osmotic pressure. In addition, due to mutual repulsion between the carboxylate anions on the cross-linked network, the polymer network bundle is stretched, and a capillary effe...

However, the water-absorbent polymer material will swell violently after absorbing urine, and the swollen diaper will surround the genitals, and rubbing the genitals for a long time will affect the normal development

Although there are many types of water-absorbing polymer materials for diapers and strong water-absorbing capacity, their antibacterial effect is poor and their skin-friendliness is not enough. Especially the pull-up pants are used for up to 8 hours, and the genitals turn red and worn out after taking them off. Frequent phenomenon
