Description

{Blind for intercepting and discolored ultraviolet rays}

The present invention relates to a blind having a transparent or semi-transparent color shade. When the blind is exposed to sunlight, the shade shields the ultraviolet rays, as well as discolors to a specific color. When the sunlight is blocked again, This invention relates to an ultraviolet screening discoloration blind.

In general, blinds, which are worn on the head to cover the sun, use uniform color such as charcoal gray irrespective of the amount of ultraviolet rays, and such conventional blinds also serve to shield ultraviolet rays from the sunlight in sunlight. However, when wearing in a shaded place without ultraviolet rays or indoors, the wearer is not easy to secure visibility, and people around him have seemingly frustrated faces. In addition, in the case of a plastic sheet produced by coating or extrusion molding a compound containing a photochromic pigment in a general plastic sheet made of an ultraviolet discoloring pigment, since the tensile strength of the plastic sheet is high, (Ultraviolet rays), the change speed of the color is very slow, or the color does not change at all. Therefore, the ultraviolet ray shielding function can not be performed in many cases, and the durability according to the amount of sunshine is remarkably deteriorated. In addition, when the plastic sheet is exposed to the sunlight (ultraviolet ray) for a long time, the pigment contained in the plastic sheet is prevented from being in contact with the pigment It is not suitable for use in blinds because it is difficult to use because it is destroyed suddenly and discoloration can not be performed.

Accordingly, the blind of the present invention is intended to prevent damage to the skin by blocking ultraviolet rays contained in sunlight when exposed to sunlight, and to return to the original color when the sunlight is interrupted. In addition, the present invention provides a blind that is easy to use even if it is worn in a dark room without shade or in a shady place, it is easy to secure visibility and visually unstable, and there is no trouble to raise or lower the awning according to the presence of ultraviolet rays. There is a purpose.

An ultraviolet barrier coloring film sheet for use as a blind shade, comprising: a top plastic film layer of transparent or translucent color;

A photochromic thermosetting resin layer coated on the lower portion of the upper plastic film layer and discolored by sunlight (ultraviolet rays); A lower plastic film layer of transparent or semi-transparent color which is adhered to the lower portion of the thermosetting resin layer 12 by an adhesive layer 13; And upper and lower hard coating portions coated on the upper end of the upper plastic film layer and the lower plastic film layer 14 to block ultraviolet rays upon exposure to sunlight and to be turned into a transparent or semitransparent awning.

As described above, the ultraviolet barrier discoloration blind according to the present invention is characterized in that when a blind of a transparent or transparent color is exposed to sunlight (ultraviolet rays), ultraviolet rays are shielded and changed to a specific color and returned to the original color when sunlight is blocked , UV rays are blocked to prevent eye fatigue and facial skin damage. In addition, it is easy to secure visibility even in dark indoor or shady places where there is no sunlight, and it is not visually unstable. It is convenient to use because there is no trouble to raise or lower sunshade according to presence of ultraviolet rays, There is an advantage.

The ultraviolet shielding discoloration film sheet (10) comprises a transparent plastic film layer (11) having a transparent or semi-transparent color, and a protective film layer ; A photochromic thermosetting resin layer 12 coated on the lower part of the upper plastic film layer 11 and discolored according to sunlight (ultraviolet rays); A lower plastic film layer 14 of transparent or semi-transparent color adhered to the lower portion of the thermosetting resin layer 12 by an adhesive layer 13; And upper and lower hard coating portions 15 and 16 coated on the upper end of the upper plastic film layer 11 and the lower plastic film layer 14 to shield ultraviolet rays when exposed to sunlight and to be transparent or semi- And is discolored.

The photochromic thermosetting resin layer 12 of the present invention is obtained by coating a compound consisting of 0.001-0.05 g of a photochromic dye per 1 m < 2 > and thermally curing at 120 DEG C for 10-15 seconds. . In addition, the photochromic dye of the present invention is obtained by coloring the Pc-Dy dye in various colors. To increase the durability, an additive such as an ultraviolet absorber and ultraviolet ray is added, and a solvent dispersion powder obtained by encapsulation and freeze- Another feature to use. In the present invention, the upper and lower plastic film layers 11 and 14 may be 0.3 mm to 0.9 mm thick, and may be formed of a sheet of polyethylene terephthalate, polyethylene terephthalate, polyethylene terephthalate, And is characterized by being either one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exemplary view conceptually showing the construction of a blind (hat) according to the present invention. FIG. 2 is a view showing a state where a blind (hat) according to the present invention is discolored when exposed to sunlight .

The ultraviolet barrier coloring film sheet 10 used in the blind 100 in the blind 100 of the present invention is formed of a transparent plastic film layer 11 of transparent or translucent color and a photochromic thermosetting film 11 which is discolored due to sunlight Layer structure consisting of a resin layer 12, a plastic film bottom layer 14 adhered to the thermosetting resin layer 12 by an adhesive layer 13, and upper and lower hard coatings 20 and 21. The transparent or semitransparent color plastic film top layer 11 and the film bottom layer 14 are preferably used by extrusion molding plastic pellets having a thickness of 0.3 mm to 0.9 mm, And the like can be used. A variety of colors can be used to give a visual beauty by using a sheet of Phyto film, a sheet of PC film or a sheet of Phy, or a film containing 0.1-10% of a color dye.

The photochromic thermosetting resin layer 12 is coated with a compound consisting of 0.001-0.05 g of a photochromic dye 16 per 1 m2 and thermally cured to produce a polyester soft resin having photochromism for 10-15 seconds Coated with a float-knife coating method on the lower part of the semi-transparent color plastic film upper layer 11 as a thermosetting type which is cured at 120 占 폚.
