Description

[Detailed description of the invention] Technical field This invention relates to slats for blinds.

-F-lined slabs 1 to 1 are conventionally made of aluminum.
It was temporarily formed, but it was blown away by the wind from outside the window.
Ii'P does not move or deform. J Rippling 11 (V weak stroke and insulation 1) 1 also has problems. In order to avoid increasing the strength, the thickness of the plate should be increased (which is contrary to key point 15 for light suspension).

There(', it has superelectric strength, is lightweight, and has 1.
A structure has also been proposed in which the slabs 1 to 1 are molded from synthetic resin and a metal film is attached to the upper surface of the slabs 1 to 1. However, in the case of the above-mentioned sludge, which has a structure in which a synthetic resin and a metal are bonded together, the physical properties Y'f such as the coefficient of thermal expansion are different between the synthetic resin and the metal.
Aging of 131 scree occurred.

PurposePurpose of this invention (well, to eliminate the drawbacks of the conventional slabs as described above, to ensure strength and heat resistance without compromising light weight, and to bend and warp γ) (1) Deterioration over time occurs. There are no slabs available.

EXAMPLE Below, an example in which the present invention is made into a q-body will be described with reference to the drawings.The substrate 1a of slabs 1 to 1 is made of a foamed resin made by combining vinyl chloride resin and ABS wax (approximately 50% each). It is extruded and formed into a corrugated shape. A thin aluminum film 2 having a thickness of 2.about.3 microns is thermally transferred onto the upper surface of the substrate 1a. 1 This aluminum thin film 2 (
1st layer of the transfer film has been transferred. The transfer film 3 is shown in FIG. A thin aluminum film 2 of 2 to 3 microns is deposited on the surface of the thin aluminum film 2 with a peeling layer 5 made of pigment interposed therebetween.An adhesive layer 7 is formed on the surface of the thin aluminum film 2 with a hiding layer 6 made of pigment interposed therebetween.

Then, the transfer process for the transfer film 3 formed as described above is performed subsequent to the forming process of the substrate 1a, and the transfer film 3 is continuously pasted onto the substrate 1a. At this point, the substrate 1a has a temperature of 170°C to 180°C immediately after molding,
When the transfer film 3 is pressed and adhered to the substrate 1a by a roller, the aluminum thin film 2 is transferred 2f to the base '+k 1 a. Then, the slat 1 whose upper surface is covered with the aluminum thin film 2 is formed using the base material 4 as a scale.

Now, the slats 1 made of 414 as described above are made of foamed resin and are light in weight, have appropriate strength, and have excellent heat insulation properties. Therefore, since the upper surfaces of the slabs 1 to 1 are covered with the aluminum thin film 2 having a mirror surface, semi-mirror surface or hairline, it has excellent resistance to heat deflection and promotes the heat insulation effect. In addition, the anti-glare effect is improved. Since the thickness of the aluminum film 2 is 2 to 3 microns, it has physical properties such as thermal expansion coefficient ``1'' with respect to the substrate 18.
°1 difference (it has almost no effect, and the slat 1 does not bend or warp due to aging. Furthermore, the aluminum l'board film 2 is thermally transferred from the transfer film 3 to the corrugated substrate 1a. Compared to the production method of directly depositing the aluminum RfJ film on the slat 1, the steps t and 1 are simpler and more productive, and the manufacturing cost i~ is lower than If' (ITI ' (=
be. ;) J30Cb natural transfer is superior in adhesion of the heat-adhesive thin film to the substrate ↑1 and uniformity of the oil film.

Note that by printing, for example, a woodgrain-like snow pattern with transparent ink between the aluminum thin film 2 and the iris separation layer 5 of the transfer film 3, and rolling the transfer film As 3 onto the slab 1-, the woodgrain pattern is printed. It is also possible to transfer a thin aluminum film from 1 to 1, such as 1 to 1.

Effects and more a) As mentioned above, this invention has the advantage of forming 44 and 1a by extrusion molding a foamed resin, and covering the upper surface of the 18 with aluminum thin film 2 by thermal transfer.
! This provides an excellent effect of providing a slat 1 that secures heat resistance without damaging ff'4 and does not cause bending or warping over time.
