Abstract

The invention discloses fragrant artificial leather and a preparation method thereof and relates to the technical field of leather. The fragrant artificial leather comprises a surface layer, wherein a finishing layer is arranged on the surface layer and comprises the components of a controlled-release fragrance finishing agent, a compatilizer and a crosslinking agent, wherein the controlled-release fragrance finishing agent is composed of the components of beta-cyclodextrin and essence, and the compatilizer refers to a water-solubility linear parent high polymer material; the preparation method of the artificial leather comprises the steps of: coating a PVC (Polyvinyl Chloride) or water-based PU surface layer on release paper, and drying the surface layer; coating a PVC (Polyvinyl Chloride) or water-based PU foaming layer on the surface layer, foaming and drying the foaming layer; coating a water-based PU adhesive on the foaming layer, pasting base cloth on the foaming layer with the water-based PU adhesive, drying to obtain an artificial layer; and rolling a layer or multiple layers of water-based PU finishing agent comprising the components of the controlled-release fragrance finishing agent, the compatilizer, the crosslinking agent and a water-based PU finishing agent (water-based polyurethane) on the surface layer of the artificial leather by a three-edition printing machine, and drying to obtain the fragrant artificial leather. The heat resistance and the durability of fragrance volatilization of fragrant artificial leather prepared by the invention are improved, and the fragrance of the fragrant artificial leather is kept above 50% after the fragrant leather is baked for 168h at 100 DEG C.

Description

technical field [0001] The invention relates to the technical field of leather, in particular to an environmentally friendly aromatic artificial leather and a preparation method thereof. Background technique [0002] With the growth of the world's population and the rapid development of the economy, natural leather cannot meet people's normal needs. Synthetic leather is widely used in clothing, manufacturing, etc. Shoes, bags, furniture, automotive interiors and other industries. [0003] With the improvement of living standards, consumers have higher and higher requirements on the environmental protection and functionality of artificial leather. The use of water-based polyurethane to replace solvent-based polyurethane is an important direction for the improvement of the environmental protection of artificial leather. For details, see "Research on the Manufacturing of Water-based Polyurethane for Foamed Synthetic Leather" edited by Wang Shanshan, Liu Shiyong, and Fan Haojun...
