Abstract

The invention discloses an antibacterial, breathable and water-absorption silver-zinc acrylic ester foam material as well as a preparation method and application of the antibacterial, breathable and water-absorption silver-zinc acrylic ester foam material. The foam hole size of the prepared foam material is small, the average deionized water absorption rate, average saline water absorption rate, average artificial urine absorption rate and average artificial blood absorption rate of the prepared foam material are larger than 18g / g, and the water retention rate within 1 hour is larger than 85%, so that the foam material is suitable for dispersing and storing water-containing fluids; in addition, antibacterial silver-zinc particles are added, so that the foam material has favorable antibacterial performance, and the highest antibacterial rate for Escherichia coli and staphylococcus aureus is up to more than 95%; and due to the addition of light calcium carbonate, the gas permeation rate is larger than 1.5*10<-2> cm<3> / (m<2>.Pa.d), so that the air permeability is good. Therefore, the lumpy soft water-absorption material disclosed by the invention is particularly suitable for the field of hygienic products.

Description

technical field [0001] The invention belongs to the field of water-absorbing materials, and in particular relates to a silver-zinc antibacterial breathable 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 o...
