A kind of preparation method of fur outsole material

Abstract

The invention relates to the field of leather, especially to a preparation method for a leather pulp outsole material. The preparation method comprises the following steps: material selection, crushing, fine grinding, mixing and stirring, binding, vacuum dehydration, compaction molding of leather, secondary dehydration, drying, etc., wherein compaction molding comprises flat plate water squeezing and large drum water squeezing, and secondary dehydration is carried out in the manner of stepwise pressurization. The preparation method has the following beneficial effects: in the process compaction molding of leather, flat plate water squeezing is used to replace traditional small drum water squeezing, so an effective dehydration effect is provided, and the material will not be damaged even dehydration in the previous procedure is not good enough; in the process of secondary dehydration, stepwise pressurization is used to replace traditional continuous stable pressurization, so the molded leather can be more easily dried.

Description

technical field [0001] The invention relates to the field of leather, in particular to a method for preparing leather pulp outsole materials. Background technique [0002] A large amount of dander will be produced during the processing of cowhide, which is usually disposed of by burning, but the burning will produce smoke, which is polluting; and direct burial, because it cannot be degraded, is also prone to pollution. [0003] For this reason, someone proposes to recycle and utilize dander to develop the outsole of leather pulp. The so-called leather pulp outsole refers to a new material obtained after production and processing using cowhide wet blue dander as the main raw material. comparable to cowhide. This kind of leather outsole has a wide range of uses. In addition to being used as shoes, it can also be used as decorative materials such as floors. [0004] At present, the commonly used leather pulp product preparation methods include: material selection, crushing, ...

AI Technical Summary

Problems solved by technology

However, the existing leather pulp product preparation method is only effective for producing leather pulp products with a thickness of less than 2.5 mm; Small rollers are easy to damage the structure of the material during rolling forming; resulting in serious quality problems such as low tensile strength and easy cracking of the material, making the material scrapped

In addition, the traditional plate pressure dehydration process generally has a constant pressure of 280 bar and a pressurization time of about 60 seconds
