Problems solved by technology

[0003] The problem existing in the existing synthetic leather scorching treatment agent is: in the subsequent embossing process, the leather material needs to be hot-pressed, so that the surface of the leather material can be printed with clear patterns and full color.
However, the existing scorching treatment agent is not resistant to high temperature, and the scorching treatment agent can only keep the scorching effect from being damaged under the hot pressing temperature of 130-140°C
The resulting contradiction is: the hot pressing temperature is 130-140 degrees, the glossy effect is good, and the embossed surface treatment cannot be realized; the hot pressing temperature is 160-180 degrees, the embossed surface treatment can be realized, but the glossy effect is poor
Using the prior art scorching treatment agent, scorching gloss and surface embossing can not be achieved at the same time

Embodiment 1

[0026] The oleic acid amide, polytetrafluoroethylene, and white carbon black were respectively coarsely crushed by a 30-type pulverizer, and sieved with a 60-mesh sieve.

[0027] Put oleic acid amide and coarsely crushed white carbon black powder into a mixer at a ratio of 50:20 for mixing and stirring to form a mixed raw material.

[0028] The obtained mixed raw materials are sent to a jet mill for micro-powder processing to make semi-finished products, and the particle size is controlled to be D50=6um.

[0029] The resulting semi-finished product and polytetrafluoroethylene are put into a mixer at a ratio of 70:30 for mixing and stirring, and then sent to a jet mill for micro-powder processing to obtain coke powder for synthetic leather.

[0030] Synthetic leather scorching powder is added with industrial solvent formula to prepare synthetic leather scorching treatment agent.

Embodiment 2

[0032] The oleic acid amide, polytetrafluoroethylene, and white carbon black were respectively coarsely crushed by a 30-type pulverizer, and sieved with a 60-mesh sieve.

[0033] Put oleic acid amide and coarsely crushed white carbon black powder into a mixer at a ratio of 40:20 for mixing and stirring to form a mixed raw material.

[0034] The mixed raw materials obtained are sent to a jet mill for micro-powder processing to make semi-finished products, and the particle size is controlled to be D50=7um.

[0035] The resulting semi-finished product and polytetrafluoroethylene are put into a mixer at a ratio of 60:40 for mixing and stirring, and then sent to a jet mill for micro-powder processing to obtain coke powder for synthetic leather.

[0036] Synthetic leather scorching powder is added with industrial solvent formula to prepare synthetic leather scorching treatment agent.

Embodiment 3

[0038] The oleic acid amide, polytetrafluoroethylene, and white carbon black were respectively coarsely crushed by a 30-type pulverizer, and sieved with a 60-mesh sieve.

[0039] Put oleic acid amide and coarsely crushed white carbon black powder into a mixer in a ratio of 60:20 for mixing and stirring to form a mixed raw material.

[0040] The obtained mixed raw materials are sent to a jet mill for micro-powder processing to make semi-finished products, and the particle size is controlled to be D50=8um.

[0041] Put the obtained semi-finished product and polytetrafluoroethylene into the mixer at a ratio of 80:20 for mixing and stirring, and then send it to the jet mill for micronization processing to obtain coke powder for synthetic leather.

[0042] Synthetic leather scorching powder is added with industrial solvent formula to prepare synthetic leather scorching treatment agent.

Abstract

The invention discloses a synthetic leather polishing coke powder and a preparation method thereof. The synthetic leather polishing coke powder comprises oleamide, polytetrafluoroethylene and white carbon black. The preparation method for the synthetic leather polishing coke powder comprises the following steps: conducting coarse crushing on oleamide, polytetrafluoroethylene and white carbon black respectively, mixing coarsely crushed oleamide and white carbon black powder, and feeding the mixture I into a jet mill for primary micro powder processing to obtain a semi-finished product; mixing and stirring the semi-finished product and polytetrafluoroethylene, and feeding the mixture II into the jet mill for secondary micro powder processing. A synthetic leather polishing coke treating agent prepared from the provided synthetic leather polishing coke powder has the relatively high temperature resistant property, is suitable for high-temperature hot-press embossing processing, and solves the technical defect in the conventional process that the color and gloss are hard to balance.

Description

technical field [0001] The invention relates to the field of synthetic leather processing, in particular to a synthetic leather scorching powder used in the surface processing technology of synthetic leather and a preparation method thereof. Background technique [0002] In the synthetic leather processing process, in the process of processing the surface of synthetic leather, it is usually necessary to apply a scorching treatment agent to the surface of the leather material to make the leather material have a strong burnt feeling, achieve a glossy surface effect, and obtain a feel and gloss close to genuine leather. Synthetic leather scorch powder is the raw material for producing synthetic leather scorch treatment agent. Synthetic leather scorch powder is prepared by adding industrial solvent to synthetic leather scorch powder. [0003] The problem existing in the existing synthetic leather scorching treatment agent is that in the subsequent embossing process, the leather ...
