Abstract

The invention provides a preparation method of thermoplastic elastomer slit bead artificial leather, which comprises the steps of: selecting and processing base cloth; composite pressing; manufacturing primary artificial leather; and manufacturing finished products. In this method, thermoplastic polyurethane elastomer (TPU) is used as the main material, and other auxiliary materials are added. After being heated, melted and mixed by an extruder, they are compounded and pressed together continuously, and then cooled to obtain an environmentally friendly artificial leather with open edge beads. According to the method for preparing artificial leather with open-edge beads provided by the invention, the produced artificial leather with open-edge beads has good folding fastness, excellent wear resistance and significantly improved color fastness, and there is no solvent and no heavy metal added in the production process, which can completely achieve cleanliness. Production, the resulting product is a fully environmentally friendly open-edge bead artificial leather.

Description

technical field [0001] The invention belongs to the technical field of artificial leather, and in particular relates to a preparation method of thermoplastic elastomer slit bead artificial leather. Background technique [0002] Open edge beads are derived from animal fur by removing the loose belly and the first layer or second layer of skin on the limbs, and then pasting PVC on the surface for modification. Open edge bead is a kind of high-grade leather with bright surface like mirror, comfortable handle and beautiful appearance. Due to the shortage of animal fur resources, and people pay more and more attention to the protection of animals, people began to imitate the open edge beads by the method of producing artificial leather. At present, polyvinyl chloride (PVC) and polyurethane (PU) are mainly used to manufacture this product. The production process of these manufacturing methods is complicated, a large amount of waste gas is generated in the production process, it ...
