Problems solved by technology

Such as Chinese invention patents CN102382264A and CN104193884, these traditional water-absorbing materials use a large amount of chemical raw materials such as acrylic acid, methacrylic acid, acrylamide, acrylate, etc., which are highly toxic, cannot be degraded naturally, and pollute the environment. Rare reports of water-absorbing materials with higher strength prepared from materials
[0003] The Chinese patent application number CN201510969536.9 discloses a natural polymer water-absorbing material and a preparation method thereof. The raw material composition of the natural polymer water-absorbing material includes by weight: 0.2-6 parts of sodium alginate, 0.2-6 parts of Gracilaria 6 parts, 70-99.5 parts of water, 0.2-20 parts of calcium chloride, using natural polymer Gracilaria polysaccharide and sodium alginate as the main raw materials, which is highly safe for people, especially infants, and the water absorption ratio reaches 100% of its own weight. Tens to hundreds of times, the tensile strength is high, and it has good water-holding properties. The product can be naturally degraded, but there is still room for further improvement in the performance of skin-friendly superabsorbent materials used in infant diapers

Abstract

The invention discloses a skin-friendly and high-water-absorbent material for infant diapers and a preparation method of the skin-friendly and high-water-absorbent material, and belongs to the technical field of water absorbent materials. The skin-friendly and high-water-absorbent material includes the following raw materials of sodium alginate, polysaccharide from gracilarria, water, calcium chloride, L-arabinose, milk fibers, and chitin fibers; and the preparation method includes the steps of mixing, stirring, gel forming and the like. According to the skin-friendly and high-water-absorbentmaterial for the infant diapers and the preparation method of the skin-friendly and high-water-absorbent material, by adopting the L-arabinose, the milk fibers and the chitin fibers as a reinforcing system, the water absorbent and mechanical properties of the skin-friendly and high-water-absorbent material for the infant diapers are improved.

Description

technical field [0001] The invention relates to the technical field of water-absorbent materials, in particular to a skin-friendly super-absorbent material for infant diapers and a preparation method thereof. Background technique [0002] Super absorbent material is a substance containing a large number of hydrophilic groups, which can absorb water tens to thousands of times its own weight. It is widely used in baby diapers, women's sanitary napkins, pet mats, gardening and other fields. It is a very meaningful research content. The water-absorbing materials developed in the past are mostly divided into two categories. One is to carry out graft reaction on natural polymers such as starch and cellulose, and add functional organic monomers to form super water-absorbing materials; the other is to use one or more Formed by polymerization of organic monomers. The safety of these two types of water-absorbing materials is restricted by the processing technology. If there are resi...
