Natural-wax-luster coloring treatment agent and preparation method thereof

Abstract

The invention discloses a natural-wax-luster coloring treatment agent and a preparation method thereof. The natural-wax-luster coloring treatment agent is prepared from the following raw materials inparts by weight: 25g of a 1 / 8 nitrocotton solution, 2.7g of epoxidized soybean oil, 10g of butanone, 5g of dimethylformamide, 15g of weak solvent wax-feeling polyurethane resin, 1.2g of fumed silica powder, 14g of methyl ester and 0.2g of a smooth hand feeling agent with a leveling property. The preparation method of the natural-wax-luster coloring treatment agent comprises the following steps: S1, stirring the 1 / 8 of nitrocotton solution, the epoxidized soybean oil, the butanone and the dimethylformamide; S2, adding the weak solvent wax-feeling polyurethane resin; S3, adding the fumed silicapowder; S4, carrying out grinding; and S5, adding the methyl ester and the smooth hand feeling agent with a leveling property, wherein the stirring process is not stopped when the raw materials are added in S1, S2 and S3. According to the invention, the drying speed and surface cracking feeling of a product are ensured, and a polishing-like effect of natural wax luster is realized.

Description

technical field [0001] The invention relates to the technical field of leather treatment, in particular to a natural waxy touch treatment agent. [0002] The invention relates to the technical field of leather treatment, in particular to a preparation method of a natural waxy touch treatment agent. Background technique [0003] Synthetic leather color-touching treatment agent, the leather made with the color-touching process is different from the traditional synthetic leather in the form of raw materials. [0004] The traditional methods of using treatment agents for synthetic leather are mainly treatment, printing, spraying, roller coating and direct coating. The leather made by these processes is covered with a layer of treatment agent for the entire sheet. [0005] The color touch process of synthetic leather is to dip the liquid raw material on a flat cloth ball, and then wipe the surface of the synthetic leather. Therefore, the surface of the synthetic leather produce...

Problems solved by technology

Excessive use of nitrocellulose oil leather leads to cracking of the leather surface

Moreover, under the color-touching process of the above two color-touching agents, because the cloth ball is wiped back and forth when the raw material is dry, the surface of the synthetic leather is glass-like and mirror-like, and the light perception is too false, so it is difficult to achieve the anti-leather effect.
