Problems solved by technology

[0003] The process of the traditional pressure change treatment process is: firstly, the synthetic leather pressure change treatment agent is applied on the surface of the synthetic leather, after water kneading treatment, then the water kneaded leather material is dried, and finally the hot pressing pressure change is carried out, which is commonly known in the industry as It is called wet pressure deformation processing. This processing method must go through two processes of water kneading and drying. Finally, the surface effect obtained by hot pressure deformation is not good in controllability, and the stability of the base color is not good.

Abstract

The invention discloses a synthetic leather pressing treatment powder, and a preparation method thereof. The synthetic leather pressing treatment powder comprises nylon powder, aluminium distearate, and white carbon black. The preparation method comprises following steps: raw materials are subjected to coarse crushing, and are mixed and stirred using a blender mixer after coarse crushing; and an airflow crusher is used for micro powder processing of a mixed raw material obtained via mixing and stirring. When a synthetic leather pressing treatment agent is prepared from the synthetic leather pressing treatment powder, two steps including water kneading and drying can be avoided in pressing treatment, production cost is reduced, the color stability of obtained leather is high, and finished product yield is higher.

Description

technical field [0001] The field of synthetic leather processing that the present invention relates to specifically relates to a synthetic leather pressure deformation powder used in a synthetic leather pressure deformation treatment process and a preparation method thereof. Background technique [0002] In the process of synthetic leather processing, an essential process is to apply synthetic leather pressure deformation treatment agent on the surface of synthetic leather, and make the background color of the leather material appear through the pressure deformation treatment process. Synthetic leather pressure change powder is the raw material for producing synthetic leather pressure change treatment agent, and synthetic leather pressure change powder is added with industrial solvent formula to prepare synthetic leather pressure change treatment agent. [0003] The process of the traditional pressure change treatment process is: firstly, the synthetic leather pressure chang...
