Description

Flame Retardant Transparent Film < RTI ID = 0.0 >

The present invention relates to a transparent high hardness film for protecting a scratch generated on a multi-use display screen installed in a public place by attaching a transparent hard film to prevent human and material damage caused by fire generation and diffusion in a closed space, Flame retardant multifunctional display protective film comprising a substrate layer and a flame retardant adhesive liquid, and imparting various screen performance improving functions as required.

Conventional display protective films have developed various functional films applied to personal displays. A high-hardness protective film for preventing scratches caused by an unspecified public using a display installed in a dense form in a closed public place such as an exhibition hall, an airport, an aircraft, a ship, a piano room, a library and the like and a functional film for improving screen performance Is required.

Recently, public place fire prevention law has been enacted, and flame retardant printing sheet has been developed for the public place construction materials. Flame-retardant printing sheet has been developed. In particular, international standard for preventing the occurrence of fire in confined space and smoke spreading during operation of airplanes and so on is implemented, and it is required to develop a film having a combination of display protection function, screen improving function and flame retarding function.

The display installed in a public place used by the unspecified public is scratching due to carelessness or intention, and due to the special multi structure of the display,

It is inevitable that it costs a lot more than the equipment price.

Displays installed in an isolated space such as an underground space, an aircraft, or a ship,

Fire spread due to combustion, and damage due to toxic smoke may occur, thus requiring legal requirements.

A flame retardant base layer and a flame retardant adhesive liquid are formed on a transparent high hardness film for protection in order to prevent human and material damage due to fire generation and diffusion in a closed space by attaching a transparent hard film to the display surface. To a transparent high hardness flame retardant multifunctional display protective film to which various screen performance improving functions are imparted.

In order to solve the above problems, the present invention relates to a transparent hard flame retardant film imparted with functionality for display protection, which comprises a substrate layer having a high hardness and a flame retardant property added to a transparent film, Functional layer of a hard coating layer, a blue light blocking layer, an anti-fingerprint layer, a diffuse reflection preventing layer, and a high-transparency coating layer are formed on the back surface of the transparent flame- retardant adhesive liquid, To prevent the occurrence of fire and diffusion, to maintain the display function by the transparent base film and the transparent adhesive liquid, to prevent the display surface damage by the hard film and the hard coating layer, and to improve the screen performance by the functional layers.

The transparent hard flame retardant film according to the present invention can prevent scratches generated on the display surface by the hardened base film or the hard coating layer, thereby reducing the expensive replacement cost of the display.

The transparency of the film and the functional layers such as the blue light blocking layer, the anti-fingerprint layer, and the anti-reflection layer improve the screen performance compared to the conventional screen, thereby reducing fatigue caused by long viewing.

The display installed in a public place or in a closed space can not be used for general display protection film which does not satisfy legal regulatory requirements due to fire, flame, and spread of smoke.

The effect of the present invention can achieve the above object by forming a substrate film and a flame-retardant adhesive liquid and a functional layer imparting transparent flame retardancy satisfying the requirements required by domestic and international standards.

1 is a cross-sectional view of a transparent hard magnetic flame retardant film according to an embodiment of the present invention.

As a means for achieving the above object, the present invention provides a transparent substrate film of polycarbonate, polyester, and polyethylene terephthalate having hardness of pencil hardness of 1H or more and optionally hard coating layer of 2H or higher, And a halogen-based flame retardant to optimize the blending ratio to apply transparent flame-retardant pressure-sensitive adhesive having adhesive strength while ensuring transparency.

Functional layers of a hard coating layer, a blue light blocking layer, a fingerprint preventing layer, a diffuse reflection preventing layer, and a high-transparency coating layer are formed or mixed on the back side, respectively.

The high hardness base film is suitably 50-250 um thick and 5-50 um thick to maintain the screen contact function of the display.

The above-mentioned transparent flame retardant film for display protection must satisfy the vertical burning requirement, SMOKE DENSITY standard and SMOKE TOXICITY standard required by the international standard.

Examples of tests for satisfying the international vertical combustion flame retardancy, smoke density, and smoke toxicity criteria are as follows.

[Example 1]

VERTICAL BURN Flame Retardant Test

Flame application time of sample After 12 seconds Residual salt time 5 seconds or less, Duration 15 seconds or less, Carbonization length 20CM or less.

[Example 2]

SMOKE DENSITY Test

Burning time 4 minutes After applying smoke density 150 or less.

[Example 3]

SMOKE TOXICITY TEST

Smoke toxicity HCN 150, C0 1000, NOX 100, SO2 100, HCl 150, HF 100 or less.
