Abstract

The invention discloses a silver antibacterial breathable water absorbing acrylic ester foam material and a preparation method and application thereof. The prepared foam foam material has small pore size, and average deionized water absorption rate, average salt water absorption rate, average artificial urine absorption rate and average artificial blood rate greater than 18 g / g, 1 h water retention higher than 85%, ans is applicable to dispersion and storage of aqueous fluid. In addition, due to the addition of silver antibacterial particles, the foam material has good antibacterial property, and has antibacterial rate on colibacillus and Staphylococcus aureus higher than 95%; due to the addition of light calcium carbonate, the material has gas transmission rate greater than 1.5*10<-2> cm<3> / (m2.Pa.d) and shows good permeability. Therefore, the massive soft water absorbing material is particularly applicable to the field of sanitary products.

Description

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