Embodiment 1

[0028] (1) Dissolving polyvinylpyrrolidone in a mixed solution of water and ethanol (the volume ratio of water and ethanol is 1:2) to obtain a polyvinylpyrrolidone solution with a concentration of 10 wt%. Chitin was dissolved in concentrated hydrochloric acid (the mass fraction of concentrated hydrochloric acid was 38%) to obtain a chitin solution with a concentration of 5 wt%.

[0029] (2) Silver nitrate solution (concentration is 0.001mol / L) is heated to 450 DEG C while stirring, and heating rate is 15 DEG C / min, then adds sodium citrate solution (concentration is 1wt%), silver nitrate solution and citric acid The volume ratio of the sodium solution was 100:3, the reaction was stirred for 20 minutes, and the nano-silver sol was obtained after cooling to room temperature.

[0030] (3) Purslane, Houttuynia cordata, and Pulsatilla pulsatillae were mixed in a mass ratio of 2:2:1, crushed to 100 mesh, washed twice with absolute ethanol, and dried to obtain Chinese herbal medicine...

Abstract

The invention discloses a water-absorbing antibacterial material and application thereof in preparation of disposable medical gloves, and belongs to the technical field of antibacterial materials. The raw materials comprise, in parts by weight, 20-30 parts of a polyvinylpyrrolidone solution, 3-5 parts of hydroxyethyl cellulose, 5-10 parts of a chitin solution, 3-5 parts of nano-silver sol, 3-5 parts of Chinese herbal medicine powder and 5-8 parts of polyester fibers. The material provided by the invention can absorb a large amount of water to keep hands dry, and has a good antibacterial effect on escherichia coli, staphylococcus aureus and the like. In addition, by adding the polyester fibers, the material has certain strength and elastic recovery capability, and the integrity of the water-absorbing antibacterial material is ensured.

Description

technical field [0001] The invention relates to the technical field of antibacterial materials, in particular to a water-absorbing antibacterial material and its application in preparing disposable medical gloves. Background technique [0002] Antibacterial materials refer to a new class of functional materials that have the function of killing or inhibiting microorganisms. There are many substances in nature that have a good function of sterilizing or inhibiting microorganisms, such as some organic compounds with specific groups, some inorganic metal materials and their compounds, some minerals and natural substances. But at present, more antibacterial materials refer to adding certain antibacterial substances (antibacterial agents), so that the material has the ability to inhibit or kill surface bacteria. [0003] During the use of medical gloves, doctors use gloves for a long time, and their hands are prone to sweat. At this time, bacteria are easy to grow and reproduce,...
