Abstract

The invention discloses a zinc-silver antimicrobial bibulous acrylic ester foam material as well as a preparation method and application thereof. The cellular size of the prepared foam material is micro; the average deionized water absorption rate, the average saline water absorption rate, the average artificial urine absorption rate and the average artificial blood absorption rate of the prepared foam material are respectively greater than 18g/g; the water retenticities of the indexes in one hour are over 85 percent respectively; the zinc-silver antimicrobial bibulous acrylic ester foam material is suitable for dispersing and storing water-containing fluid; in addition, by adding zinc-silver antibacterial particles, the foam material has good antibacterial performance; the antibacterial rates of the foam material for escherichia coli and staphylococcus aureus respectively reach over 95 percent. Therefore the block soft water-absorbing material disclosed by the invention is particularly suitable for the field of sanitation supplies.

Description

technical field [0001] The invention belongs to the field of water-absorbing materials, and in particular relates to a silver-zinc antibacterial water-absorbing acrylate foam material and a preparation method and application thereof. Background technique [0002] In today's hygienic products, the water-absorbing material inside is mainly granular synthetic resin. After absorbing water, urine or blood, it will form a gel, which is easy to form agglomerates, making it difficult to fix in one position. It is very uncomfortable in the actual use process. Comfortable. Therefore, it is of great significance to develop block-shaped soft water-absorbing materials. [0003] Normal blood is composed of blood cells, plasma, etc. The diameter of blood cells is about 8 μm, and the diameter of acrylic acid molecules is much smaller than that of blood cells. Therefore, blood cells are not easily absorbed by the gel-like superabsorbent resin, and can only stay on the surface of the super...
