Embodiment 1

[0030] A weak solvent cotton slippery translucent leather treatment agent is characterized in that, according to parts by weight, it includes the following raw materials: 150 parts of 1 / 8 second nitrocellulose, 7 parts of 1 / 16 nitrocellulose, 7 parts of weak solvent resin, moistening 37 parts of wet wax, 7 parts of dry auxiliary agent, 3.5 parts of cotton wax auxiliary agent, 46 parts of soybean oil, 65 parts of butanone, 12 parts of cyclohexanone, 300 parts of anti-white water, 320 parts of ethyl acetate.

[0031] A kind of technical scheme is to provide the preparation method of weak solvent cotton slippery translucent leather treatment agent, it is characterized in that, comprises the following steps:

[0032] S1: mixing and stirring of 1 / 8 second nitrocellulose, 1 / 16 second nitrocellulose, weak solvent and soybean oil;

[0033] S2: Stir and add wetting wax, drying additive, cotton wax additive;

[0034] S3: add weak solvent resin;

[0035] S4: Add a weak solvent and disp...

Embodiment 2

[0038] This embodiment provides a weak solvent cotton slippery translucent leather treatment agent component and a preparation method thereof, the steps are the same as those in Example 1, and the components are different in that:

[0039] 5 parts of 1 / 8 nitrocellulose, 5 parts of weak solvent resin, 33 parts of wetting wax, 6 parts of drying additive, 3 parts of cotton wax additive, 40 parts of soybean oil, 60 parts of butanone, 10 parts of cyclohexanone, 230 parts of white water, 300 parts of ethyl acetate.

Embodiment 3

[0041] This embodiment provides a weak solvent cotton slippery translucent leather treatment agent component and a preparation method thereof, the steps are the same as those in Example 1, and the components are different in that:

[0042] 10 parts of 1 / 8 nitrocellulose, 10 parts of weak solvent resin, 40 parts of wetting wax, 8 parts of drying additive, 4 parts of cotton wax additive, 50 parts of soybean oil, 70 parts of butanone, 15 parts of cyclohexanone, 310 parts of white water, 350 parts of ethyl acetate.

[0043] The weak solvent smooth and translucent treatment agents prepared in the above three examples can solve the problems of side white light and oily waxy light in the surface treatment of high-grade leather products without increasing the cost, so as to meet the needs of market development and open up new markets.

[0044] Explanation: The carrier resin modulus of the weak solvent treatment agent is lower than that of the strong solvent treatment agent, so it has ...

Abstract

The invention relates to an eco-solvent smooth and transparent leather treatment agent and a preparation method thereof, and belongs to the technical field of leather coatings. The preparation methodcomprises the steps of S1, mixing and stirring 150 parts by weight of 1 / 8 second nitrocotton, 5-10 parts by weight of 1 / 16 second nitrocotton, 300-400 parts by weight of an eco-solvent and 40-50 partsby weight of soybean oil; S2, stirring and adding 33-40 parts of wetting wax, 6-8 parts of a dry auxiliary agent and 3-4 parts of a cotton wax auxiliary agent; S3, adding 5-10 parts of weak solvent resin; and S4, adding 300-350 parts of an eco-solvent, and completely dispersing. The preparation method disclosed by the invention is scientific and reasonable, the acerbity wax feeling auxiliary agent and the wet feeling auxiliary agent are matched with the eco-solvent wax feeling resin and the two types of nitrocotton, the eco-solvent smooth and transparent treatment agent is provided, the problems of side white light, insufficient oil wax light and the like existing in surface treatment of high-grade leather products are solved without increasing the cost, the market development requirements are met, and new markets are exploited.

Description

technical field [0001] The invention relates to the technical field of leather coatings, in particular to a weak-solvent cotton slippery and bright leather treatment agent and a preparation method thereof. Background technique [0002] With the development of the leather industry, strong solvent-based surface treatment agents have the problem of side white light and insufficient waxy light, which greatly limits their application in high-grade leather. Leather glossy series products such as ordinary brightening, oil-permeable oil leather and other strong solvent brightening series products are made into leather, there will be white light when viewed from the side, and the surface is still lacking in waxy luster. In order to solve the problem of adding luster to high-grade leather, water-based environmental protection treatment agents are generally used in the market, but the hydrolysis resistance of water-based treatment agents is not enough, and the cost is generally high, w...
