Embodiment 1

[0130] The enzyme depilatory aid of the present embodiment is made of the following raw materials in mass percentage:

[0131] Potassium hydroxide 8; sodium percarbonate 11; sodium hydroxide 9; calcium hydroxide 14; compound phosphate 1; the balance is deionized water.

[0132] The preparation method of enzyme depilatory auxiliary agent is made up of following process steps:

[0133] A, sodium percarbonate, sodium hydroxide are mixed uniformly to make mixture, according to mass ratio is mixture: deionized water=1:2.2 ratio adds deionized water, stirs under normal temperature and makes suspension;

[0134] B. Calcium hydroxide is made into an aqueous solution with a mass percentage of 45%, and calcium hydroxide aqueous solution and composite phosphate are added to the suspension prepared in step A, and deionized water is added and stirred at normal temperature. Add potassium hydroxide and the rest of deionized water and mix evenly to make an enzyme depilatory aid with an alkal...

Abstract

The invention relates to an enzyme unhairing assistant in tanning production, particularly an enzyme unhairing assistant and a preparation method thereof. The enzyme unhairing assistant is prepared from effective quantities of potassium hydroxide, sodium percarbonate, sodium hydroxide, calcium hydroxide, composite phosphate and deionized water. The preparation method comprises the following steps: evenly mixing the sodium percarbonate and sodium hydroxide to prepare a mixture, preparing the calcium hydroxide into a 45-65 wt% water solution, adding the calcium hydroxide water solution and composite phosphate into the suspension prepared in the step A, adding the deionized water, stirring the room temperature, adding the potassium hydroxide and the rest of deionized water, and uniformly mixing to obtain the slightly alkaline enzyme unhairing assistant. The enzyme unhairing assistant solves the technical problem that the enzyme unhairing assistant in the prior art can not be easily popularized on a large area, can easily cause environmental pollution and the like, has the advantages of favorable unhairing effect, simple preparation method and the like, and satisfies the requirement for clean production in the unhairing process.

Description

technical field [0001] The invention relates to an enzyme depilatory auxiliary agent in tanning production, in particular to an enzyme depilatory auxiliary agent and a preparation method thereof. Background technique [0002] At present, the environmental pollution problem of my country's tanning industry is eye-catching, especially in some areas where tanning enterprises concentrate water pollution is more serious. In terms of its characteristics, tannery wastewater not only produces a large amount, but also is a kind of complex and high-concentration organic wastewater, which contains a large number of substances harmful to the environment. Different types of leather, different finished leather (shoe upper leather, garment leather, sofa leather, luggage leather, etc.), the water quality of tannery wastewater varies greatly, which increases the difficulty of treatment. [0003] On December 3, 2009, the Ministry of Industry and Information Technology issued the "Guiding Opi...
