At present, the traditional method of making pearlescent effect leather generally uses pearlescent powder to achieve the desired effect. It has a certain settling characteristic, and it needs constant stirring during the finishing process, and often there will be uneven stirring and blooming phenomenon, especially when the configured pearlescent coating liquid is left, the pearlescent powder will be produced after standing for several hours. Hard precipitation, it is difficult to disperse again, so it often causes a lot of waste, which increases the cost of tanning enterprises

Abstract
A pearlescent paste for leather and a preparation method thereof belong to the technical field of new materials in the leather industry and a preparation method thereof. It is characterized in that its composition and ratio are: modified casein: 30%-80%, sulfited oil 3%-10%, organic base 0.6%-1%, pearl powder 3%-20%, thickening Agent 1% to 2%; the sum of the above components is 100%. The pearlescent powder in the traditional pearlescent coating is changed into the form of pearlescent paste, and a series of pearlescent paste products can be obtained by changing the color of the pearlescent paste, which simplifies the finishing process, improves the stability and feel of the pearlescent powder, and saves raw materials.
Description
technical field [0001] The invention relates to a finishing auxiliary agent for leather surface treatment, in particular to a pearl paste for leather and a preparation method thereof. Background technique [0002] The main purpose of leather finishing is to increase the durability of the leather surface, correct the defects of the leather surface, improve the use value of the leather, expand the scope of use of the leather and increase the variety of leather designs. As a special effect leather, pearlescent effect leather occupies a place in high-grade leather products. At present, the traditional method of making pearlescent effect leather generally uses pearlescent powder to achieve the desired effect. It has a certain settling characteristic, and it needs constant stirring during the finishing process, and often there will be uneven stirring and blooming phenomenon, especially when the configured pearlescent coating liquid is left, the pearlescent powder will be produced...
