Problems solved by technology

[0005] In the above production steps, the mirror surface release paper is coated with the fabric, middle material and base material, and finally the mirror surface release paper is combined with the microfiber semi-finished product, and drying is required when coating each layer of slurry Then apply the next layer, and then combine the release paper and the microfiber semi-finished product. It is necessary to preheat both the release paper and the microfiber semi-finished product, and then stick them together. This kind of operation process will extend the production process route during processing. , resulting in a waste of energy

Abstract

The invention discloses a production process of mirror-surface synthetic leather. The technical scheme has the essentials that the production process comprises the following steps: step 1: preparing base cloth, and preparing wet-process slurry and dry-process slurry; step 2: uncoiling the base cloth to reach a coating machine through a cloth storage rack, and coating the wet-process slurry; coagulating in a coagulating tank, washing with water, drying and cooling; then coiling to generate a base; step 3: after coating the dry-process slurry on release paper, drying; step 4: after drying, continuing to re-coat the dry-process slurry and then drying to be semi-dry; step 5: fitting the release paper, which is dried to be semi-dry, to the base layer, and drying by a drying oven; step 6: after drying, stripping the release paper and sticking the dry-process slurry on the base; and step 7: coiling. The synthetic leather produced by the production process has the characteristics of high transparence and bending resistance and has an excellent wear-resisting performance.

Description

technical field [0001] The invention relates to the field of synthetic leather, in particular to a production process of mirror surface synthetic leather. Background technique [0002] Polyurethane artificial leather and synthetic leather, because their properties are close to genuine leather, have developed rapidly in China in recent years. Improving product quality and developing new varieties have become the direction of efforts of various PU leather manufacturers. Regarding the production process of PU. [0003] Mirror leather refers to the PU leather made of mirror release paper. It is named for its smooth and bright surface. This kind of leather is mainly used in women's clothing, shoes and handbags. It is favored by women because of its bright color. [0004] The Chinese patent with publication number 102535187A discloses a method for making non-creased microfiber mirror synthetic leather. A layer of non-crease film is formed on the surface to make a superfiber semi-...
