Problems solved by technology

[0004] The technical problem mainly solved by the present invention is: the present invention is aimed at the traditional leather cleaning agent that contains a large amount of chemical surfactants and soap bases, which are easy to remain on the leather after use, chemical surfactants are difficult to degrade, and are easy to pollute the environment. The leather is not bright enough after cleaning, and a large amount of pungent odor will be produced. A preparation method of a pure biomass leather cleaner is provided. The invention firstly ferments fresh milk to obtain raw yogurt, and then extracts tanned yogurt from banana peels. quality enrichment liquid, mix egg white and rice washing water, and finally mix and ferment the three, add natural antiseptic ingredients, and concentrate to get leather cleaning agent

Abstract

The invention relates to a preparation method of a pure-biomass leather cleaner and belongs to the technical field of leather cleaners. The preparation method comprises the steps that firstly, fresh milk is fermented to obtain raw yogurt, then tannin rich liquid is extracted from banana peels, egg white and washing water of rice are mixed, finally, the three substances are mixed and fermented, a natural preservative component is added, and the leather cleaner is obtained after concentration. According to the preparation method, lactic acid in the raw yogurt serves as a natural decontaminant, crude fibers in the washing water of rice serve as a friction agent to remove stains in leather, after cleaning is finished, tannin in the banana peel extracts and proteins in the leather are combined, hide which is compact, tough and not prone to decaying is formed on the surface of the leather, finally, the yogurt as well as proteins and lipid contained in the egg white can serve as a substitute of paraffin, a protective film is formed on the surface of the leather, the gloss of the leather can be maintained easily, no undesirable odor is generated, safety and environmental friendliness are achieved, and the preparation method has broad application prospects.

Description

technical field [0001] The invention relates to a preparation method of a pure biomass leather cleaner, belonging to the technical field of leather cleaners. Background technique [0002] During the process of leather tanning, oil is introduced into the interior of the animal skin to form an oil film that fully covers the surface of the fibers in the skin, which reduces the friction between the fibers in the leather and makes the leather very soft. However, during the use of the leather, this layer of oil film will slowly volatilize, consume, or be destroyed by other reasons. At this time, the fibers inside the leather will rub against each other and bond to each other, thus hardening become brittle. Therefore, leather needs to be maintained during the use of leather products. [0003] Common leather cleaning agents include: surfactants, fatliquoring agents, moisturizing agents, polishing agents, etc. Surfactants can emulsify and remove pollutants on the leather surface, ...
