Abstract
The invention discloses a production method for high-intensity reflective films. The preparation method comprises the steps of: 1, unwinding a PET film, coating the PET film with waterborne polyurethane resin, uniformly planting glass beads on the waterborne polyurethane resin after warming, and warming to shape and winding, thus at last obtaining a PET bead planted film; 2, placing the PET bead planted film into a vacuum coating device, heating the metal layer by 10V and 0.5A direct current to enable the metal layer to be uniformly attached to the glass bead layer of the PET bead planted film to form a reflective layer; 3, extruding polyurethane and titanium dioxide which are mixed according to a ratio of 4:1 by two screws and coating on the 25-micron PET film to form a film, fitting with the reflective layer and then forming a composite film by 100-degree hot pressing; 4, stripping the PET film of the composite film, and then laminating with a PVC film on a grain hot pressing machine with specific shape to form a honeycombed reflective film; 5, coating the PET film with pressure-sensitive resin, and compounding with the honeycombed reflective film to form a finished product. The invention also provides a production method for the high-intensity reflective film which is more environment-friendly.
Description
Technical field
The present invention relates to new material manufacturing technology, specifically a kind of manufacture method of high-strength reflecting film.
Background technology
Intensity level reflective membrane, with its stronger reflex reflection performance, obtains widespread use in fields such as road, space flight, navigation, mining.Be applied at present the most universal high-strength reflecting films taking high refractive index glass micro pearl as reflective original paper exactly such as communications and transportation.Existing high intensity level, is all that solvent type resin is produced, and it is a large amount of solvent evaporates in process of production, has brought very large destruction to environment.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of high-strength reflecting film, the more environmental protection of this high-strength reflecting film.
For achieving the above object, the invention provides following technical scheme:
A manufacture method for high-strength reflecting film, comprises the following steps:
(1) PET film is unreeled, and be coated with waterborne polyurethane resin at PET film, after drying temperature, on waterborne polyurethane resin, sod uniformly glass microballoon, then dry temperature sizing rolling, finally obtain PET bead planted film;
(2) PET bead planted film is put into vacuum coating equipment, and with the direct current heating of metal layer of 10V, 0.5A, metal level is attached in the soot layer of PET bead planted film uniformly and forms reflection horizon;
(3) with twin-screw, the polyurethane particles of mixing in 4: 1 ratios and titanium dioxide are extruded and are applied to film forming on the PET film of 25um, after then closing with the metal level laminating in reflection horizon through 100 DEG C of hot pressing formation composite membranes;
(4) the PET film of composite membrane is peeled off, then, with the pressing under the condition of 180 DEG C of temperature on the lines heat-sealing machine of given shape of PVC film, formed cellular reflective membrane;
(5) by thick 10um pressure-sensitive resin-coated on PET film, be compounded to form finished product with described cellular reflective membrane.
As further scheme: the described aqueous polyurethane thickness of step (1) is 0.1-0.5nm, described in sod glass microballoon temperature be 80-90 DEG C, described sizing rolling temperature is 100-120 DEG C.
As further scheme: the described metal layer thickness of step (2) is 1-10nm.
As further scheme: the atmospheric pressure in the described vacuum coating equipment of step (2) is 4.0-5.0*10
-2pa.
As further scheme: in step (4), the thickness of described PVC film is 50-75um.
As further scheme: in step (1), can carry out plant with metallocene layer PE film, form PE bead planted film.
Compared with prior art, the invention has the beneficial effects as follows: the more manufacture method of the high-strength reflecting film of environmental protection is provided.
