Aromatic and antibacterial tanning agent based on plane grass extract and preparation method thereof

Abstract

The present invention discloses an aromatic antibacterial tanning agent based on a fragrant eupatorium herb extract, and a preparation method thereof, wherein a fragrant eupatorium herb water extract, one or a plurality of fragrant eupatorium herb solvent extracts, and one or a plurality of aromatic agents are compounded to obtain the aromatic antibacterial tanning agent. According to the present invention, after single tanning through the aromatic antibacterial tanning agent of the present invention, the leather shrinkage temperature can be close to 90 DEG C, the aroma retaining time of the leather is more than 180 days, and the good inhibition effects are provided for bacteria adopting staphylococcus aureus as the representative, yeast adopting Cryptococcus albidus as the representative, mould adopting Aspergillus niger as the representative, and other leather bacteria; the fragrant eupatorium herb being the harmful invasive plant is subjected to resource utilization, such that the fragrant eupatorium herb can become the treasure, and the significant economic benefits can be generated so as to achieve the two purposes; and the aromatic antibacterial tanning agent of the present invention has three functions of tanning, aromatic property and antibacterial property, and can provide a new selection for the multi-functional leather chemical industry material.

Description

technical field [0001] The invention belongs to the technical field of functional leather chemical materials and preparation methods thereof, and in particular relates to an aromatic and antibacterial tanning agent based on extracts of japonica grass and a preparation method thereof. Background technique [0002] Leather and its products have excellent hygienic properties such as air permeability and water vapor permeability, and have been more and more widely used in people's daily life, including clothing, bags, furniture, decorations, etc. With the continuous development of human society, people's requirements for leather and its products are also increasing. For example, in addition to the basic functions of conventional leather clothing, durable luggage and furniture, requirements such as comfort, safety, pleasure, and individuality have also been put forward, which also calls for the birth and vigorous development of functional leather chemical materials. For example, ...

Problems solved by technology

However, the problem is that when entering the retanning process, the collagen fibers in the leather have been combined with the tanning agent and finalized (Shi Kaiqi, Yin Weigang, Li Ya, etc. Research on the fixation of animal tissues by tanning. Leather Science and Engineering , 2011,21(6):39-42.), which makes ① the tanning agent filled or combined inside the collagen fibers and in the fiber gaps will hinder the combination of the retanning agent and leather collagen fibers; ② the retanning agent It can also be combined with tanning agents to form macromolecules, which is not conducive to its penetration into the collagen fibers, which will eventually lead to limited binding ability between the retanning agent and skin collagen fibers, and it is mainly distributed in the collagen fiber gap

It is difficult to control and treat the aircraft grass after it invades, and there is no mature resource utilization method
