Problems solved by technology

The traditional coating method of leather embryo mainly has the following process steps: repairing → grinding → sizing bottom → drying → re-skinning → primer → sizing bottom → drying → grinding → primer → drying → middle coating → drying → topping Coating→drying→applying brightener→drying→applying feel agent, the process steps are cumbersome, it takes a long time to work, it takes a lot of labor, and each drying requires a lot of electricity, and it takes many times in the process of finishing Spraying solvents, most of the solvents used are toxic and flood the entire workshop, causing environmental pollution. In addition, the natural properties of the leather obtained after processing with this process are often weakened, affecting the properties of the leather. Using this traditional process The quality of the products obtained is uneven, and some products have a low quality level, which affects the interests of leather processors

Embodiment Construction

[0017] The embodiments of the present invention will be described in detail below with reference to specific examples, so as to fully understand and implement the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects.

[0018] Embodiments of the present invention are:

[0019] The finishing method for making high-grade waxed leather from low-grade leather includes the following process steps:

[0020] (1) Preparation of skin embryos: use low-grade blue leather to make semi-vegetable tanned embryos, and emboss and shape the semi-vegetable tanned embryos;

[0021] (2) Repair wounds: The semi-vegetable tanned embryos embossed and shaped in step (1) are scraped and repaired with a scraping agent, and the components and contents of the scraping agent are: per square foot of semi-vegetable tanned embryos; Take the dosage as an example: polishing repairing agent 1.4g, pigment paste 0.167g, thickening age...

Abstract

The invention relates to the technical field of a leather coating decoration method, and provides a coating decoration method for making high-grade waxing leather from low-grade leather with the advantages that the process is simple, the operation is convenient, used solvents have low toxicity, the natural attributives of softness, ventilation and the like of real leather are maintained, and the qualification rate is high. The method mainly comprises the following steps of leather blank preparation, defect repair, baking, plate pressing, polishing, mechanical foaming, falling, toggling, top coating, beating softening and sand plate pressing.

Description

technical field [0001] The invention relates to the technical field of leather finishing methods, in particular to a finishing method for making high-grade waxed leather from low-grade leather. Background technique [0002] At present, most of the original skins have flaws on the surface, such as uneven surface of the skin embryo, rough pores, scars and other problems, so the original skin needs to be processed. The processing and processing of raw hides are highly valued by leather processors, and the price of processed leather is determined by its quality. The same batch of leather, due to the different quality after processing, is finally distinguished by grade, and the price varies greatly. The traditional coating method of the skin embryo mainly includes the following process steps: repairing injury → dermabrasion → sizing bottom → drying → regrinding → primer → sizing bottom → drying → grinding → bottom coating → drying → middle coating → drying → top Coating→drying...
