Embodiment Construction

[0030] The production method of Europa fleece-like polyurethane synthetic leather includes wet tanning, dry release paper transfer, embossing and foaming treatment, kneading, rolling, and finished product inspection, specifically including the following steps:

[0031] (1), coating the polyurethane coating on the base cloth makes the semi-finished product of wet-process synthetic leather;

[0032] (2), select the release paper, and then apply a layer of polyurethane slurry on it. After the polyurethane slurry is formed into a film, the release paper is torn off, and the polyurethane film after film formation is bonded to the printed surface through the adhesive layer. The surface of the wet-process synthetic leather semi-finished product is transferred to the pattern of the release paper;

[0033] Described polyurethane slurry is formed by mixing the following raw material components by weight:

[0034] Polyester polyether copolymer resin SF-01 100

[0035] Expanded microsph...

Abstract

The invention discloses a production method of Europa suede-feel polyurethane synthetic leather, which comprises the following steps: firstly, preparing semifinished synthetic leather by using a wet method; secondly, hot-joining the polyurethane slurry layer, which is formed after the pattern of release paper is transferred, onto the surface of the semifinished synthetic leather which is printed by the wet method, wherein the polyurethane slurry comprises the following raw materials in parts by weight: polyester-polyether copolymer resin SF-01, 3-7 parts of expanded micro particle, 8-12 parts of butanone, 5-10 parts of solvent-type pigment and 0.2-0.5 part of modified silicone high polymer BYK-95950; thirdly, embossing and foaming by using embossing rollers; and finally, crinkling. The invention enables the surface of the polyurethane synthetic leather to have strong suede feel and barbing effect. The polyurethane synthetic leather has the advantages of high wear resistance, high peeling, high cold resistance, high hydrolysis resistance and other physical properties. The polyurethane synthetic leather is exactly like leather and is high-quality environmental-protection high-grade synthetic leather. The whole process conforms to the requirements of environmental protection, and conforms to the development trend of professional shoe materials in modern times.

Description

technical field [0001] The invention relates to a production method of polyurethane synthetic leather, in particular to a production method of Europa cashmere polyurethane synthetic leather. Background technique [0002] With the development of social economy, people's quality of life is improving day by day, and people's requirements for clothing, lodging and transportation are getting higher and higher, especially shoes, bags, sofas, etc. that are commonly used in daily life. It needs to be like the natural texture and texture of genuine leather, with good moisture permeability, wear resistance and scratch resistance, soft texture and high elasticity. However, general artificial leather and synthetic leather do not have a strong sense of genuine leather, their quality is low, and their usability is not good, so they cannot meet the needs of the market. Contents of the invention [0003] The invention provides a production method of Europa velvety polyurethane synthetic ...
