Embodiment Construction

[0037] This anion and anion charge adjustment resin is prepared by mixing acrylic resin, polyurethane resin, protein resin, softener, neutral wax solution, weak cationic wax solution, cationic resin and water. The proportion of each component is calculated by weight:

[0038] 1. Charge adjustment resin prepared with domestic raw materials

[0039] A. Acrylic resin: 500-800

[0040] B. Polyurethane resin: 200-300

[0041] C. Protein resin: 15-30

[0042] D. Softener: 30-40

[0043] E. Neutral wax solution: 50-150

[0044] F. Weak cationic wax solution: 50-150

[0045] G. Cationic resin: 200-300

[0046] H, water (distilled water): 800-1000

[0047] The preparation method of this anion and cation charge adjustment resin comprises the following steps:

[0048] (1) Weigh acrylic resin, polyurethane resin, protein, softener, neutral wax solution, weak cationic wax solution, cationic resin, water (distilled water) according to the proportion

[0049] (2) Add the negative acr...

Abstract

An anion and cation charge control resin is a finishing material used on the surface of tanning leather, and belongs to the field of leather finishing. The anion and cation charge control resin solves the problem that the leather products using Nappa leather, aniline leather and slunk as the raw materials lose the original softness, and becomes hard and poor in hand feeling in the traditional leather cleaning and maintenance process, also solves the technical problem that anion and cation resin can not be used at the same time. A technical scheme is as below: adding anion acrylic resin, polyurethane resin, protein resin and a softening agent into a container, and stirring uniformly for stand-by; adding a neutral wax liquid, a weak cation wax liquid and water into another container, and stirring uniformly. adding the cation resin into the mixed liquor of wax liquid, and stirring uniformly; and finally, adding the mixed liquor of the cation resin into the mixed liquor of the various anion resin, stirring uniformly and filtering to obtain the anion and cation charge control resin.

Description

1. Technical field [0001] The invention relates to the technical field of leather surface finishing, in particular to a coating and film-forming agent for leather surfaces with strong water absorption—resin. After the resin is coated on the surface of leather products, a soft and bright coating will be formed on the leather surface, giving the leather a fresh and beautiful feeling. 2. Technical background [0002] 1. The scheme of prior art [0003] In order to be fashionable and beautiful, most of the current leather garments are made of light and soft nappa leather, aniline leather and fetal calf leather as raw materials. This kind of leather has a silky feeling due to its lightness and softness. It is chic and elegant to wear, beautiful and generous, and has won the favor of consumers. However, this kind of leather is particularly water-absorbent, and the traditional finishing methods are far from meeting the cosmetic cleaning and finishing requirements of these leather...
