Description

Yangbuck scorching treatment agent for synthetic leather and preparation method thereof

technical field

The invention relates to a surface treatment agent for synthetic leather, in particular to a yambuck scorch treatment agent for synthetic leather applied in the back-end process of synthetic leather, and also relates to a preparation method of the yangbuck scorch treatment agent for synthetic leather.

Background technique

As a substitute for natural leather, synthetic leather has the characteristics of convenient processing, uniform quality, and diverse varieties. It makes up for the lack of genuine leather resources and covers almost all areas where genuine leather is used. Compared with genuine leather, synthetic leather can satisfy people's more surface needs. style requirements. In the field of synthetic leather manufacturing, surface treatment is a technology that has been paid more and more attention, and it is an effective way to increase the added value of products. Surface treatment processes include printing, spraying, direct coating, multi-functional roller coating, etc. Among them, printing is one of the most commonly used processes for surface treatment of synthetic leather by anilox rollers. In addition to changing the color and luster of the leather surface, the surface treatment process is also used to change the touch of the leather surface, such as oily waxy, powdery waxy, sandy, and smooth, making the surface of synthetic leather feel more like genuine leather. Form different surface styles, such as yangbuck effect, nubuck effect, crazy horse effect, etc. However, in the existing yangbuck effect synthetic leather surface treatment agents, the scorching treatment effect is not obvious, unnatural, and the hand feel is poor. At the same time, the treatment reagents are easy to pollute the environment, the manufacturing cost is high, and the comprehensive treatment effect is not good.
