Description
Technical Field
The invention relates to the technical field of synthetic leather, in particular to a manufacturing method of high-performance automobile seat synthetic leather.
Background
The raw leather used for producing natural leather is limited, and the production of the natural leather is a process with high energy consumption and high pollution, which brings great pollution load to the environment. In recent years, developed countries such as the european union have also proposed new standards for the safety of natural leather itself, and toxic chemicals such as Cr (vi), azo dyes, pentachlorophenol (PCP), and free formaldehyde present in natural leather have been strictly limited. The production of natural leather faces great challenges from the standpoint of hide resources, environmental protection, product safety and the market.
Synthetic leather is a composite material which simulates the tissue structure and the service performance of natural leather and can be used as a substitute of the natural leather. Usually, a non-woven fabric is used for simulating a net-shaped layer, a microporous polyurethane coating is used for simulating a grain surface layer, the front surface and the back surface of the obtained synthetic leather are very similar to leather, and the synthetic leather has certain air permeability and is closer to natural leather than common artificial leather, so that the synthetic leather is widely used for manufacturing shoes, boots, bags, balls and the like.
At present, a solvent-based production process is mainly adopted for producing the polyurethane synthetic leather, and the basic process flow of the production process is as follows, namely non-woven cloth or woven cloth → a solvent-based polyurethane wet solidification coating (bottom layer) → water washing → drying → a solvent-based polyurethane dry film transfer coating (upper layer). The following significant technical problems exist with this production process. Firstly, a solvent type polyurethane wet-process solidification coating is used as a bottom layer, and the wet-process solidification coating is solvent type Polyurethane (PU)) Coating the slurry on the surface of the non-woven fabric by using a roller coater, and then feeding the slurry into the' H2And (3) solidifying the PU by using an O-DMF (dimethyl formamide) solidifying bath to form a film with a microporous structure. DMF (dimethyl formamide) is used as a solvent in the process, and the solvent pollution of DMF can be caused in the processing process. Moreover, water cannot completely replace DMF in polyurethane, so that DMF residue of the product is caused, and finally the product safety problem is caused. Such product security issues may limit the product from entering the premium market among numerous technical and trade barriers. Secondly, a solvent type polyurethane wet-process solidification coating process is adopted, great energy consumption is needed for drying, at present, the energy consumption needed by one production line is 115 KW/hour of electric energy, and 70 ten thousand kilocalories/hour of steam. Thirdly, a solvent type polyurethane wet-process solidification coating process is adopted, a special DMF recovery device is needed, high energy consumption is needed, and at present, the device for recovering 20 tons of DMF in one set of months is put into about 350 ten thousand yuan.
China is a big country for global synthetic leather production, the production capacity and the total production amount are ranked first in the world, and the annual output accounts for more than 80% of the total annual output in the world. According to published data of China's petrochemical union, the yield of enterprises with artificial leather synthetic leather of more than scale in 2016 years is 332.6 ten thousand tons. According to data statistics of the customs administration, the export total amount of the artificial leather synthetic leather in 2016 of China is 65.5 ten thousand tons and accounts for 19.7 percent of the total output, the export total amount is 25.9 hundred million dollars, and the export total amount rises by 5.2 percent compared with the export total amount of 25.2 dollars in 2015. However, the current synthetic leather still adopts a solvent type production system, so that the problem of serious solvent pollution is caused, the health of industrial workers is damaged, the products are limited to enter high-end product markets at home and abroad, and the problem of product safety caused by solvent residue is easily caused.
