Abstract

The invention discloses a method for manufacturing embossed solvent-free polyurethane synthetic leather. The method comprises the steps of preparing a solvent-free polyurethane leather dry-process semi-finished product and carrying out each unit process of embossing treatment. According to the method disclosed by the invention, the manual work is little, the energy consumption is low, and both the manufacturing process and the finished product are healthy and environmentally friendly; and the product can be embossed, patterns are plump, the granular sensation is high, the physical property is high, and the cold resistance and hydrolysis resistance are excellent. According to the method, the traditional wet process is not required, and links of producing a wet-process base and carrying out dry-process bonding are avoided; and solvent-free foaming layer resin is also not required, and the used solvent-free bicomponent surface layer resin can serve as a surface layer and can also serve as a bonding layer.

Description

[0001] 1. Technical field [0002] The invention relates to a method for manufacturing polyurethane synthetic leather, in particular to a method for manufacturing embossed solvent-free polyurethane synthetic leather, which belongs to the field of synthetic leather manufacturing. [0003] 2. Background technology [0004] Because the production process of traditional synthetic leather requires the use of a large amount of organic solvents such as N,N-dimethylformamide (DMF), and the final product also contains a small amount of organic solvent residues. This process is not conducive to people's health no matter for consumers or producers and processors; at the same time, for the environment, it will seriously damage the ecological environment and affect the atmospheric conditions. The production of environment-friendly polyurethane synthetic leather to replace traditional synthetic leather will be imperative. In the environment-friendly polyurethane synthetic leather, since the...
