Description

A kind of production method of ultra-thin imitative polyurethane leather
Technical field
The invention belongs to artificial synthetic leather technical field, and in particular to a kind of production method of ultra-thin imitative polyurethane leather.
Background technology
Imitative PU leather is characterized in top layer for polyurethane (PU), and bottom is PVC, both removes from office good feel, outward appearance, thoroughly with PU Gas, the tractable characteristic of moisture-inhibiting and surface, but with PVC leather advantage durable in use, cheap, the market competitiveness is strong, The fields such as production case and bag, clothes, footwear, furniture, sports goods are widely used in, the 30~40% of dermatine yield have been accounted for.
At present, in the production method of artificial leather, rubbing method (including direct rubbing method and transfer coated method) is artificial leather Main manufacture methods., it is necessary to resin, solvent-borne type surface layer resin and solvent welding at solvent-borne type table in the manufacturing process of artificial leather At glue, table resin etc. assign leather add lustre to, delustring and various effector functions, at these tables resin, surface layer resin and adhesive glue with Based on solvent type PU or acrylic acid, organic solvent is inflammable and explosive, smell is big, toxicity is big, both there is potential safety hazard, and work is endangered again Author is physically and mentally healthy.In addition, there is surface effect low with PU product similarities, stripping and hydrolysis etc. in the artificial leather for preparing at present Physical property does not reach the defect of use requirement.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of production method of ultra-thin imitative polyurethane leather, the producer Method is environmentally friendly, and the surface effect of the imitative PU products of manufacture is high with PU product similarities, the physical property such as stripping and hydrolysis Better than PU products.
For achieving the above object, the technical solution adopted by the present invention is：
A kind of production method of ultra-thin imitative polyurethane leather, comprises the following steps：
(1) after, polyurethane cover is processed using pretreating reagent, in 120~130 DEG C of drying；
(2), applied on the polyurethane cover of step (1) and scrape foaming layer slurry, placed into dry with 170~175 DEG C in baking oven It is dry；
(3), to add on step (2) foaming layer slurry apply after hydrolysis resin and scrape adhesive layer, place into baking oven with 155 ~160 DEG C of dryings；
(4) adhesive layer and full viscose glue base fabric for, taking step (3) are processed in three editions list processors；
(5), the polishing material of step (4) carries out later stage treatment and obtains ultra-thin imitative polyurethane leather finished product.
Also including fretting map treatment in above-mentioned steps (2).
Also include bonding process in above-mentioned steps (4).
Above-mentioned steps (5) later stage is processed includes embossing, polishing, cross water rubs line, product inspection packaging process.
The foaming layer slurry of above-mentioned steps (2) is foam polyvinyl chloride layer slurry.
The adhesive that adhesive layer is used in above-mentioned steps (3) is aqueous adhesive polycarbodiimide, polyaziridine or ring Oxygen tree fat.
To reduce environmental pollution, the consumption of organic solvent is reduced, the adhesive that adhesive layer is used in above-mentioned steps (3) is water Property adhesive polycarbodiimide, polyaziridine or epoxy resin.
Beneficial effects of the present invention：
The present invention carries out pre-treatment to polyurethane cover, it is had more preferable scratch resistance, physical strength, and bottom has been used specially Hydrolysis resin, base fabric is used to use full viscose glue base fabric, product is by carrying out later stage treatment, the imitative PU leather of preparation after three editions treatment Finished product can reach the surface effect of PU products, and the stripping of product and hydrolysis etc. are physical better than PU products.The imitative PU leather for preparing End properties are excellent, and with preferable outward appearance and soft and smooth feel, long-term use not fugitive color is suitable for making case and bag, clothes, footwear Class, furniture, sports goods etc..
Specific embodiment
