Chitin nanofiber anti-microbial colloid glove and preparation method thereof

Abstract

The invention relates to a preparation method of a chitin nanofiber anti-microbial colloid glove. The method comprises the following steps: S1, preparing chitin nanofiber dispersion liquid: mixing 90-120 parts of chitin nanofiber, 1-5 parts of a dispersant and 800-3900 parts of water in parts by mass to prepare the chitin nanofiber dispersion liquid; S2, preparing chitin nanofiber dipping adhesivecement: mixing and homogenizing 5-20 parts of the chitin nanofiber dispersion liquid prepared in step S1, 90-120 parts of latex, 0-3 parts of a cross-linking agent and 1-5 parts of a thickening agentin parts by mass to prepare the chitin nanofiber dipping adhesive cement; S3, dipping an unprocessed glove into the chitin nanofiber dipping adhesive cement prepared in step S2; and S4, vulcanizing and drying the glove, which is subjected to treatment in step S3, to obtain the chitin nanofiber anti-microbial colloid glove. According to the preparation method, the chitin nanofiber anti-microbial function can be further applied into disposable colloid anti-microbial gloves, not only does the method not damage the molecular structure of chitin, but also the application range of chitin fiber is extended. The invention further relates to a chitin nanofiber-containing colloid glove.

Description

Technical field [0001] The invention relates to a chitin nanofiber antibacterial rubber glove and a preparation method thereof. Background technique [0002] Chitin (C 8 H 13 O 5 N)n, also known as chitin and chitin, the English name is Chitin. Chitin is the only natural polymer material with its own positive charge in nature. It is a natural alkaline polysaccharide. The chemical structure of Chitin is very similar to that of cellulose. The difference lies in the C-2 hydroxyl group of each glucose unit. Is replaced with acetamido (—NHCOCH 2 ), get chitin. The annual output of chitin in nature can reach 10 tons. It is the second most abundant sugar after cellulose, and the resources are very rich. Chitin is widely used because of its sterilization and disinfection effects. Among them, there are some reports on the application of chitin to yarn fibers. The specific preparation process is to mix chitin and yarn fibers into a molten state, then spin it, and finally spin into antib...

Problems solved by technology

Among them, there are some reports on applying chitin to yarn fibers. The specific preparation process is to mix chitin and yarn fibers, make them into a molten state, and then spin them, and finally weave them into antibacterial clothes or gloves. This process can make antibacterial clothes or gloves, but the application range of this method is very narrow, especially it cannot be applied to disposable gloves

In addition, the melt spinning of chitin and yarn fibers will not only destroy the molecular structure of chitin nanofibers due to high temperature, resulting in a significant decline in its antibacterial properties, but also requires a lot of heat and consumes a lot of energy.
