Low-foam easily-biodegradable efficient leather penetrant and preparation method thereof

Abstract

The invention relates to the field of textile additives, and concretely relates to a low-foam easily-biodegradable efficient leather penetrant and a preparation method thereof. The leather penetrant is prepared from, by weight, 1 to 10 parts of isooctanol phosphate, 0.1 to 1.5 parts of sodium hydroxide, 2 to 15 parts of isopropanol and 78 to 96 parts of water. The low-foam easily biodegradable efficient leather penetrant has the following advantages: the penetrant is a penetrant which is small in foaming amount and easy to biodegrade, and does not pollute the environment after being discarded;the penetrant is nontoxic and has little harm to human bodies; and the permeability is superior to that of a penetrant JFC, the soaking time can be further shortened, and the production efficiency isimproved.

Description

technical field [0001] The invention relates to the field of textile additives, in particular to a low-foaming and easily biodegradable high-efficiency leather penetrating agent and a preparation method thereof. Background technique [0002] The broad concept of penetrant refers to a class of chemicals that can help the substances that need to penetrate to penetrate the substances that need to be penetrated. They also have fixed hydrophilic and lipophilic groups, which can be oriented on the surface of the solution and can make the surface tension significantly To drop substances, the industry generally uses surfactants (which can be anionic or nonionic) or organic or inorganic solvents. In the processes of immersion, degreasing and hair removal in the leather processing process, penetrants need to be added to make the raw leather soften quickly and evenly, and shorten the immersion time. The currently commonly used penetrant is mainly penetrant JFC, fatty alcohol polyoxyet...

AI Technical Summary

Problems solved by technology

At present, the commonly used penetrant is mainly penetrant JFC, fatty alcohol polyoxyethylene ether, which is a non-ionic surfactant that is not easy to biodegrade, and it is easy to cause environmental pollution after being discarded.
