Embodiment Construction

[0044] A production method of polyurethane synthetic leather with simulated leather effect, including wet tanning, printing treatment, dry release paper transfer, kneading, rolling, and finished product inspection, specifically including the following steps:

[0045] (1) Coating polyurethane coating on the base cloth to prepare semi-finished wet synthetic leather;

[0046] (2) Use a printing roller to coat polyurethane finish on the surface of the semi-finished wet synthetic leather for printing surface treatment. The vertical depth of the pattern of the printing roller is 1.0-1.5mm.

[0047] Polyurethane finishing agent is made by mixing the following raw materials in parts by weight:

[0048] ST-2120 90-100

[0049] Dimethylformamide 120;

[0050] The viscosity of the polyurethane finishing agent is 800cps / 25℃-1500cps / 25℃. If the viscosity of the finishing agent is large, the leather surface will transfer more slurry during printing; if the viscosity is low, the leather surface will tr...

Abstract

The invention discloses a method for producing real leather intimating polyurethane synthetic leather, which comprises the following steps: firstly, preparing a wet synthetic leather semi-finished product; secondly, coating a polyurethane finishing agent on the surface of the wet synthetic leather semi-finished product to perform printing surface treatment; thirdly, sticking a release paper pattern transferred polyurethane film to the surface of the printed wet synthetic leather semi-finished product, wherein raw materials in polyurethane slurry comprise polyester-polyether-polycarbon copolymerized polyurethane resin, cracking resin, dimethyl formamide, down powder, wet wax sensitive toner and solvent pigment; and finally, performing kneading treatment. The polyurethane synthetic leather has frosting effect on the surface, smooth handfeel, color change when pushing the surface by hand and strong third dimension of patterns, has good physical properties such as scratch resistance, cold resistance, hydrolysis resistance and the like, and can replace real leather in many aspects so as to reduce the requirement for furs, protect the nature and keep ecological balance.

Description

Technical field [0001] The invention relates to a production method of polyurethane synthetic leather, in particular to a production method of polyurethane synthetic leather with a simulated leather effect. Background technique [0002] Crazy horse leather is a kind of animal leather with frosted and discolored surface, which is mainly used in casual shoes, women's boots, clothing and bags. Due to the strong three-dimensional surface pattern and the distressed matte effect on the surface, the market has great demand for Crazy Horse leather. However, Crazy Horse leather is scratch-resistant, not durable, and expensive. There are also some polyurethane synthetic leathers similar to Crazy Horse leather on the market, but they have defects such as hard hand feeling, poor fullness, weak leather feeling, and poor durability. It is difficult to meet market demand. Summary of the invention [0003] The invention provides a method for producing a polyurethane synthetic leather with a cr...
