Abstract

The invention discloses an air-permeable and water-absorbent acrylate foam material with silver and zinc anti-bacteria particles, as well as a preparation method and application of the air-permeable and water-absorbent acrylate foam material. The size of foam cells of the prepared foam material is tiny, the average deionized water absorption rate, the average brine absorption rate, the average artificial urine absorption rate and the average artificial blood absorption rate are all larger than 18g / g, the water retention rate in an hour is more than 85%, and the acrylate foam material is suitable for dispersing and storing fluids containing water; additionally, due to addition of the silver and zinc anti-bacteria particles, the manufactured foam material has good anti-bacteria performance, and the anti-bacterial rate of escherichia coli and staphylococcus aureus are both more than 95%; due to addition of light calcium carbonate, the air penetration amount is larger than 1.5*10-2cm3 / (m2*Pa*d), which shows good air permeability. Therefore, the block-shaped soft water-absorbent material is especially suitable for the field of toilet articles.

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 a blood cell is about 8 µm, and the diameter of the acrylic molecule is much smaller than that of a blood cell. Therefore, blood cells are not easily absorbed by the gel-like superabsorbent resin, and can only stay on the surface o...
