| titleOfInvention | Method for manufacturing eco-type leather packing and eco-type leather packing produced by this method |
| abstract | The manufacturing method of the eco-type leather packing according to the present invention devised to achieve the above object comprises the steps of: (a) a step of removing unnecessary parts for leather production including hair and fat under alkaline conditions from the peeled raw skin; (b) a tanning step of performing a tanning treatment on the leather that has undergone the step (a); (c) a dyeing step of dyeing the leather by adding a dye to the leather passed through step (b); (d) a pretreatment step of adding a hardener and a water-repellent agent to the leather passed through step (c); And (e) characterized in that it comprises a drying step of impregnating the polysulfide-based polymer mixture into the leather passed through step (d). According to the present invention, water, a water-soluble hardener and a water- and water-repellent agent are pretreated by penetrating into the interior of natural leather to minimize environmental pollution, and manufacture an eco-type leather packing which can promote the stability of the packing form during storage and use of the leather packing. It can work. In addition, according to the present invention, after the pretreatment process, the functional polysulfide polymer mixture is penetrated into the fine pores and the flesh layer of the natural leather to apply the leather surface, and then dried to dry the oil resistance, chemical resistance, elasticity and water resistance of the leather packing. By improving the physical properties such as the like there is an effect that can be produced in a high-quality eco-type leather packing mainly installed in the pump for transferring the fluid, such as paint. |
