Abstract
The invention relates to a method for preparing a PU transfer membrane, which comprises that: (a) water-poking treatment is applied to plain woven oxford cloth; (b) a wet-process polyurethane (PU) coating is plated on the plain woven oxford cloth; (c) a PU dry-process transferring coating with a leather grain is compounded on the wet-process polyurethanecoating; (d) the plain woven oxford cloth is stripped and the PU transfer membrane is prepared. The water-poking treatment for the oxford cloth reduces the adhesive force between the PU transfer membrane and the oxford cloth; thereby the purpose of stripping is achieved effectively. Hand feel, flexibility and permeability of the membrane are improved by a microspore structure inside the wet-process polyurethane coating. The dry-process transfer coating is a PU coating with a leather grain, thus increasing the effect of leather imitation. The PU transfer membrane prepared by the method can be used as materials for car interior decoration such as an attaching leather membrane for a panel mesa. The PU transfer membrane can also be compounded with such substrates as underlayer oxhide, micro fiber leather, etc. to the surface of which the PU wet-process coating is hardly applied, thus the PU transfer membrane is manufactured into imitating leather with good leather effect.
Description
technical field [0001] The invention relates to a method for making a PU transfer film, which belongs to the field of plastic film production technology. Background technique [0002] Existing plastic films, including TPU (thermoplastic polyurethane) films, are generally produced by calendering, extrusion, blow molding, etc., and are made after cooling and shaping. They are used as inner and outer layer materials of composite films and are used in various foods. , soup stock and packaging film for daily necessities, etc., composite materials for textiles, etc. The film made by the above method has no microporous structure inside, has no real leather effect in hand feeling and appearance, and cannot be used to make artificial leather synthetic leather. Contents of the invention [0003] The present invention aims to propose a method for making a PU (polyurethane) transfer film, which can produce a PU transfer film with a microporous structure inside, a leather effect in ha...
