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 polyurethane coating; (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
The present invention relates to a kind of preparation method of PU divert film, belong to the plastic film production process field.
Background technology
Existing plastic sheeting, comprise TPU (thermoplastic polyurethane) film, process productions such as general employing rolling process, extrusion molding, blowing, behind cooling and shaping, make, ectonexine material as laminated film, be applied to the packing film of various food, soup stock and household items etc., the composite of textile etc.The inner pore-free structure of the film made from said method, feel, outward appearance do not have leather effect, can't be used for making real leather intimating synthetic leather.
Summary of the invention
The present invention is intended to propose the preparation method of a kind of PU (polyurethane) divert film, and can make inside has microcellular structure, and it is the PU divert film of 0.3-0.6mm that feel, outward appearance have leather effect, thickness.
The preparation method of this PU divert film comprises that (a) does drying to the plain weave oxford and handle, (b) on the plain weave oxford, apply wet polyurethane (PU) coating, (c) compound PU dry method with corium lines is transfer coated on above-mentioned wet polyurethane coating, (d) the plain weave oxford is peeled off and is made the PU divert film.Wherein: (a) the plain weave oxford in the step adopts the plain weave oxford that the polyester filament of 75D～150D is made, dryingagent is hydroxyl or amino polysiloxane-based waterborne organic silicon class emulsion, the drying processing procedure is the waterborne organic silicon class emulsion with plain weave oxford impregnation 0.8%～3%, then oven dry.
The plain weave oxford is peeled off it at last only as carrier in the preparation method of this PU divert film, is not the part of product; The drying of oxford is handled the bonding force that makes PU divert film and oxford and is reduced, and peels off thereby reach effectively.Thereby wet polyurethane coating inside has microcellular structure to improve film feel, elasticity and gas permeability, and dry method is transfer coated for to have the PU coating of corium lines, increases its skin emulation effect.The PU divert film of making in this way can be used for automobile-used interior material, as table top applying epithelium of instrument board etc., also can be difficult to do on its surface the base material of PU wet-process coating mutually compound with double-layer fur, micro fiber leather etc., and make the good emulation skin of leather effect.

The specific embodiment
As shown in Figure 1, the preparation method of this PU divert film comprises that (a) does drying to the plain weave oxford and handle, and (b) applies wet polyurethane (PU) coating on the plain weave oxford that drying was handled; (c) compound dry method is transfer coated on above-mentioned wet polyurethane coating, makes the PU coating with corium lines; (d) the plain weave oxford is peeled off, made the PU divert film.
The equipment that the present invention uses is: what roll out equipment, storage cloth holder, band pressure roller contains immersion trough, rinsing bowl, wet-process coating equipment, dry coating equipment, drying and shaping equipment and peel-off device etc.
In the preparation method of this PU divert film, (a) can to adopt through, broadwise be the plain weave oxford that the polyester filament of 75D～150D is made to the plain weave oxford in the step, and for example the crochet needle number is 104 * 80/ per inch, fabric width 155cm, thickness 0.15mm.Dryingagent can adopt hydroxyl or amino polysiloxane-based waterborne organic silicon class emulsion, and for example Shanghai is as a waterborne organic silicon dryingagent of the RF-5020 model of Chemical Industry Science Co., Ltd's production.The drying processing procedure is the waterborne organic silicon class emulsion with plain weave oxford impregnation 0.8%～3%, then oven dry.Technological process as shown in Figure 2.The batching of waterborne organic silicon emulsion (by weight) is:
Pure water: 100 parts;
3～10 parts of waterborne organic silicon dryingagents (solid content 30%).
(b) step PU wet-process coating processing comprise damping, be coated with, solidify, operations such as washing, oven dry, its technological process is as shown in Figure 3.Wet method formula of size (by weight) is:
100 parts of polyurethane resins;
30～50 parts of DMF;
2～3 parts in solvent borne colorant;
5 parts of wood powders.
(c) the step dry process comprise that the top of release liners is coated with, primary coat, with operations such as the applying of PU wet-process coating, oven dry, maturation.Its technological process such as Fig. 4.Dry method slurry technical recipe (top is coated with or primary coat) by weight is:
100 parts of polyurethane resins;
10～50 parts of solvents;
10～15 parts in colorant;
1 part of levelling agent.
The category of category, colorant and the filler of wet method slurry and the used polyurethane resin of dry method slurry and consumption are by the requirement of the rerum natura of PU divert film and tone and different.Solvent in the dry method slurry is DMF and MEK combination solvent.
(d) peel angle and peel distance can be controlled at suitable numerical value in Bu the stripping process.Peel angle is defined as PU divert film and the formed angle of carrier oxford when peeling off, and can be controlled between 20 °～45 °.Peel distance is defined as the distance of pick-up point and rolling point, can be controlled between 1.5mm～3mm.So both reached effectively and peeled off, the suffered tension force of PU divert film can recovered within the elastic range, thereby guaranteed product quality.PU divert film stripping technology flow process as shown in Figure 5.
