High-mirror-surface leopard print synthetic leather and preparation method thereof

Abstract

The invention discloses high-mirror-surface leopard print synthetic leather which comprises a base cloth layer, a wet-process polyurethane layer, a dry-process polyurethane layer and a high-mirror-surface layer, wherein the surface of the top of the base cloth layer is coated with the wet-process polyurethane layer, and the surface of the top of the wet-process polyurethane layer is coated with the dry-process polyurethane layer. The invention also discloses a preparation method of the fabric. The preparation method comprises the following steps: step 1, preparing base cloth; step 2, coating wet-process polyurethane; step 3, coating dry-process polyurethane; and step 4, spraying a high mirror surface. By synchronously improving materials, components and the preparation process, the product performance is improved, and meanwhile the manufacturing cost is reduced. Through cooperation of leopard print release paper and the high-mirror-surface layer, the high-mirror-surface leopard print synthetic leather which is bright in gloss, high in refractive index and high in thickness is prepared, and the high-mirror-surface leopard print synthetic leather has good moisture permeability and air permeability, is soft, full and light in hand feeling, is richer in style and appearance of natural leather, and is low in cost and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of polymer polyurethane synthetic leather manufacture, in particular to a high-mirror leopard-print synthetic leather and a preparation method thereof. Background technique [0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as its substitute material. Usually, the impregnated non-woven fabric is used as the mesh layer, and the microporous polyurethane layer is used as the grain layer. Its front and back are very similar to leather, and has a certain degree of air permeability, which is closer to natural leather than ordinary artificial leather. It is widely used in the preparation of shoes, boots, bags and ball games. [0003] With the rapid development of synthetic leather technology, synthetic leather has become one of the necessities in people's daily life, and leopard print occupies an eye-catching position in the fashion indu...

AI Technical Summary

Problems solved by technology

In the field of synthetic leather, paper-grain products have become more and more widespread, but the paper-grain gloss, texture and color distribution of ordinary leopard-print synthetic leather products are uniform, and the tone is single, lacking three-dimensionality and visual impact, and the feel and There are also certain limitations in performance; at the same time, its preparation process is complicated, the manufacturing cost is high, it is not easy to promote in a large area, and it cannot meet market demand
