Description

Technical Field

[0001] The utility model relates to the technical field of PU synthetic leather production and processing, in particular to an energy-saving oven for a PU synthetic leather production roller coating line. Background Art

[0002] PU synthetic leather, also known as polyurethane synthetic leather, has a chemical name of polyurethane in Chinese. It is made of polyurethane resin dissolved in a specific solution to make a slurry, which is then coated on the base fabric. After the resin gradually solidifies, a microporous polyurethane grain layer is formed, which is what we usually call the base layer. Subsequently, through dry veneer molding and post-processing processes such as embossing and spraying, PU synthetic leather with various types, patterns and effects is produced.

[0003] During the production and processing of PU synthetic leather, coating is usually applied on its surface by roller coating, and then it is dried in an oven. However, during the heating and drying process, odor will be generated, which will have a certain impact on the health of the workers. The current oven does not have the function of removing odor. Therefore, we proposed an energy-saving oven for PU synthetic leather production roller coating line to solve the above problem. Utility Model Content
