Description
Technical field
The present invention relates to technical field of synthetic leather, in particular to a kind of manufacturing method of high-performing car seat synthetic leather.
Background technique
It is limited for the raw material skin that produces natural leather, and the production of natural leather is high energy consumption, a high pollution
Process can bring great pollutional load to environment.In recent years, safety of the developed countries such as European Union to natural leather itself
New standard is proposed, it is stringent to limit Cr (VI), azo dyes, pentachlorophenol (PCP) and free first present in natural leather
The toxic chemicals such as aldehyde.From the perspective of raw material skin resource, environmental protection, product safety and market, the production of natural leather
All suffer from greatly challenge.
Synthetic leather is the institutional framework and service performance for simulating natural leather, and can be used as the compound of natural leather substitute
Material.Lamina reticularis, with microvoid polyurethane coating simulation grain layer, obtained synthetic leather positive and negative are usually simulated with non-woven fabrics
It is all quite similar with leather, and there is certain gas permeability to be widely used in production than common artificial leather closer to natural leather
Shoes, boots, luggage and ball etc..
Currently, the production of Synthetic Leather mainly uses solvent type production technology, typical process flow is as follows: non-
Woven cloths or textile cloth → solvent borne polyurethane wet coagulation coating (bottom) → washing → drying → solvent borne polyurethane dry method
It moves on membrane coat (upper layer).Using this production technology, there are following great technical problems.First, wet using solvent borne polyurethane
Method gel coating makees bottom, and wet coagulation coating is to be coated on solvent borne polyurethane (PU) slurry non-woven using coating roller
The surface of cloth, subsequently into " H2O-DMF " coagulating bath makes PU solidify and form the film with microcellular structure.In this technique
Solvent is made using DMF (dimethylformamide), process will cause the solvent contamination of DMF.Moreover, water can not be complete
The DMF in polyurethane is replaced, the DMF residue problem of product can be caused, ultimately cause product safety problem.And this product safety
Problem, can be in numerous technical barriers and trade barrier, and limitation product enters up-market.Second, using the poly- ammonia of solvent type
Ester wet coagulation coating process, it is dry to need biggish energy consumption, currently, energy consumption needed for a production line is that electric energy 115KW/ is small
When, 700,000 kilocalories of steam/hour.Third, needing special DMF to recycle using solvent borne polyurethane wet coagulation coating process
Device, while it being also required to higher energy consumption, currently, just the device of the 20 tons of DMF of recycling in a set of month is dropped in 3,500,000 yuan or so.
China is the big country of global synthetic leather production, and production capacity and production ranking the first in the world, annual output account for generation
80% or more of boundary's gross annual output amount.It announces data according to petrochemical industry federation of China to show, China's artificial leather synthetic leather rule in 2016
The above enterprise production of mould is 332.6 ten thousand tons.It is shown according to another General Administration of Customs's data statistics, China's artificial leather synthetic leather outlet in 2016
Total amount is 65.5 ten thousand tons, accounts for the 19.7% of total output, exports 25.9 hundred million dollars of total amount, year-on-year 2015 year 25.2 is on dollar
Rise 5.2%.But since current synthetic leather still uses solvent type production system, it can not only generate serious solvent contamination and ask
Topic damages the health of industrial worker, and limitation product enters domestic and international high-end product market, and is easy to produce because of solvent
Residual and caused by product safety problem.
