Embodiment 1

[0030] Add 34.1 g of fatty alcohol polyoxyethylene ether and 11.3 g of alkyl glycoside into the beaker, mix and stir evenly, and stir at a stirring speed of 100 r / min for 30 min. After adding 55.7 g of deionized water, stir for 30 minutes to obtain the product of the present invention.

Embodiment 2

[0032] Add 25g of fatty alcohol polyoxyethylene ether and 20g of alkyl glycoside into the beaker, mix and stir evenly, and stir at a stirring rate of 100r / min for 30min. After adding 55 g of deionized water, stir for another 30 minutes to obtain the product of the present invention.

Embodiment 3

[0034] Add 45 g of fatty alcohol polyoxyethylene ether and 55 g of deionized water, and then stir for 30 minutes at a stirring rate of 100 r / min to obtain the product of the present invention.

[0035] According to the product of above-mentioned preparation, carried out application comparative test, its result is as follows table 1:

[0036]

[0037] From the above test results, it can be seen that the synergistic effect of fatty alcohol polyoxyethylene ether and alkyl glycoside can effectively inhibit the generation of foam, and can make leather products achieve excellent degreasing effect.

Abstract

The invention relates to a high-efficiency low-foam type degreasing agent. The high-efficiency low-foam type degreasing agent consists of the following components in percentage by weight: 20 to 40 percent of fatty alcohol-polyoxyethylene ether, 20 to 40 percent of alkyl glycoside, and 20 to 60 percent of deionized water. Leather is degreased by using the high-efficiency low-foam type degreasing agent; and the high-efficiency low-foam type degreasing agent has the effects of deeply and efficiently degreasing the leather, can remove interfibrillar substance, is convenient and economic and is an ideal degreasing agent special for the leather.

Description

technical field [0001] The invention relates to the technical field of leather fatliquor, in particular to the development of a high-efficiency low-foaming degreasing agent. Background technique [0002] Degreasing agent, also known as oil stain remover, is a special-purpose detergent surfactant. In daily life, all kinds of civilian detergents such as soap, washing powder, liquid detergent, etc. are commonly used to remove oily stains under the action of hydraulic power. For heavy oil stains, general-purpose detergents and even strong solvents often seem powerless. [0003] In the process of tanning or fur manufacturing, especially the degreasing of raw hides and furs with high oil content is a very critical process. Only when the natural oil contained in the bare hide is removed to a certain amount can the collagen fibers be loosened and the channel opened for The subsequent tanning and other processes are carried out smoothly to create favorable conditions, so that the f...
