The processing method that the purpose of this invention is to provide a kind of polytetrafluoroethylmicroporous microporous membrane Waterproof Breathable type artificial leather, this method be with the polyurethane solutions blade coating on release liners, to fit through the polytetrafluoroethylmicroporous microporous membrane of biaxial tension again, make polyurethane-polytetrafluoroethylene (PTFE) bidirectional elastic film after the oven dry.Adopt adhesive, this film and cloth is compound, be prepared into artificial leather with Waterproof Breathable characteristic.
The object of the present invention is achieved like this: a kind of processing method of polytetrafluoroethylmicroporous microporous membrane Waterproof Breathable type artificial leather, and its step is as follows:
A, in charging basket, add solvent, start the agitator high-speed stirred, make solvent in charging basket, produce vortex, progressively add the polyurethane particles material, make it in the solvent vortex, to suspend, polyurethane particles material dissolving back adds diluent, be diluted to 10～30%, make polyurethane solutions, described polyurethane solutions is coated on the release liners, will fit with the release liners that is coated with polyurethane solutions through the polytetrafluoroethylmicroporous microporous membrane of biaxial tension again, working pressure equipment pressurization back oven dry, after the oven dry, release liners and described polytetrafluoroethylmicroporous microporous membrane are peeled off, obtained polyurethane-polytetrafluoroethylene (PTFE) bidirectional elastic film;
B, use adhesive are combined with each other polyurethane-polytetrafluoroethylene (PTFE) bidirectional elastic film and cloth, make to have Waterproof Breathable type artificial leather, and complex method is dusting, powder point, slurry point, two point, fusion glue point, crackle film, spraying or blade coating.
Compared with the prior art the present invention has following advantage:
1, the artificial leather that utilizes the present invention to prepare, vapor transfer rate and water pressure resistance height, technology is simple, cost is low, has remarkable economic efficiency and social benefit.
2, facts have proved, can process artificial leather with Waterproof Breathable characteristic by the present invention.The vapor transfer rate of this artificial leather is up to 8431g/m
224h (pressing dry agar diffusion method test among the GB/T12704-91), water pressure resistance 83Kpa (pressing the GB4744-84 test).This artificial leather can be widely used in sportswear, insulated cold wear, footwear boots etc.
