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.

Embodiment 1

[0025] Nylon powder, aluminum distearate and white carbon black are respectively coarsely crushed through a 30-type pulverizer, and sieved with 60 mesh. The nylon powder, aluminum distearate, and white carbon black are roughly crushed in a ratio of 15:50:35 and put into the mixer for mixing and mixing to form a mixed raw material. The output rate of the mixer is 100kgs / 30 minutes .

[0026] The mixed raw materials are put into the feeding tank, and then sent to the jet mill through the feeding pot for fine powder processing. The inlet air temperature is 2°, the jet mill speed is 4500 rpm, and the jet mill discharge rate is 20kgs / 60 minutes.

[0027] The particle size of the obtained synthetic leather compressed powder is D50=6um.

[0028] The synthetic leather compression powder prepared by the above steps is added to the synthetic leather compression treatment agent prepared by the industrial solvent formula, and the synthetic leather is subjected to dry compression processing: the...

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 synthetic leather processing field that the present invention relates to, specifically relates to a synthetic leather compression powder used in a synthetic leather compression treatment process and a preparation method thereof. Background technique [0002] In the synthetic leather processing process, an indispensable process is to apply a synthetic leather compression treatment agent on the surface of the synthetic leather, and to make the leather base color appear through the compression treatment process. Synthetic leather compression powder is the raw material for the production of synthetic leather compression treatment agent. Synthetic leather compression treatment agent is prepared by adding industrial solvent formula to synthetic leather compression treatment agent. [0003] The process of the traditional pressure change treatment process is: firstly, the synthetic leather pressure change treatment agent is painted on the surface of the synthetic...
