Description

Blue-light-proof ink for glass
Technical Field
The invention relates to the technical field of printing ink, and particularly relates to blue-light-proof printing ink for glass.
Background
The liquid crystal display adopts the LED backlight technology, the LED lamp projects light on the light guide plate through a direct-in type or a side-in type, and the light guide point on the light guide plate converts a line light source into a surface light source. Among them, the side-in type is the most commonly used type, and the side-in type is to place the luminous body (lamp tube or LED lamp) at the side of the light guide plate, and the LED lamp passes through the high light transmission rate of the light guide point, and the light guide point is calculated by a computer, so that the light of the light guide plate is refracted into the surface light source, and since the backlight needs the effect of white light, the white light is formed by mixing the yellow fluorescent powder with the blue LED lamp. Since a blue LED or the like is a subject hardware, the blue spectrum in such white light has a peak, thereby forming harmful blue light. Harmful blue light has extremely high energy and can penetrate through crystalline lens to reach retina, causing atrophy and even death of retinal pigment epithelial cells. The death of light-sensitive cells will lead to a loss of vision or even complete loss, which is irreversible. The lens in human eyes absorbs part of blue light and gradually becomes turbid to form cataract, most of the blue light penetrates through the lens, especially the lens of children is clear and cannot effectively resist the blue light, and therefore macular degeneration and cataract are easily caused.
One of the existing blue light prevention technologies is to filter blue light through software, the configuration on hardware is unchanged, but internal signals are correspondingly processed before imaging, and partial blue light is filtered. The scheme has the advantages that the implementation is simple, but the experience is influenced because the picture displayed by less blue light is obviously yellow; the other scheme is a hardware scheme, and is a technical innovation from the aspects of LED backlight materials and the like generally, and can filter over 90 percent of blue light.
Disclosure of Invention
Aiming at the problems, the invention provides blue light prevention ink for glass, which is printed on one side surface of a glass light guide plate close to an incident light source or a glass cover plate of a display screen, so that the color temperature of emergent light can be effectively reduced, the light intensity of blue light is weakened, and the phenomena that the picture of the display screen is bluish and the damage to eyes is caused by blue light filtering are avoided.
In order to achieve the purpose, the invention is solved by the following technical scheme:
the blue-light-proof printing ink for glass is characterized by comprising the following raw materials in percentage by mass:
18-35% of dibasic ester, 15-30% of methyl methacrylate, 15-30% of cyclohexanone, 8-15% of slow drying solvent, 6-9% of perfume, 3-6% of silicon dioxide, 1-3% of slow dry paste, 1-3% of glycerol, 0.5-1% of titanium dioxide, 0.5-1% of flatting agent and 0.5-1% of defoaming agent.
Specifically, the slow-drying solvent is one or a mixture of more of 783 slow-drying water, ethylene glycol diacetate, ethylene glycol ethyl ether acetate, diisobutyl ketone, ethyl triethoxy propionate, propylene carbonate, dipropylene glycol monomethyl ether, ethylene glycol monobutyl ether, trimethylbenzene and tetramethylbenzene.
Specifically, the slow dry paste is one or a mixture of barium sulfate, talcum powder, calcium carbonate and aluminum hydroxide.
Specifically, the leveling agent is one of acrylic resin, urea resin, melamine formaldehyde resin, butyl cellulose, carboxymethyl cellulose and fluorocarbon.
Specifically, the defoaming agent is one of emulsified silicone oil, a high-alcohol fatty acid ester compound, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropylene amine ether, polyoxypropylene glycerol ether, polyoxypropylene polyoxyethylene glycerol ether and polydimethylsiloxane.
The invention has the beneficial effects that:
firstly, a blue light LED light source is used as a light source of the display screen, because the color temperature of the blue light LED light source is high, most of emergent light is reflected outside the light guide plate if the light guide plate is not processed, the picture of the display screen is blue, and the display effect is influenced, when the blue light-proof ink is printed on one side surface of the glass light guide plate close to an incident light source, the color temperature of the emergent light can be effectively reduced, the light intensity of the blue light is weakened, the yellow fluorescent powder layer is irradiated by the blue light with weak light intensity, the emergent light is soft white light after reaching the display screen, and the image quality of the;
the second, because the glass apron is far away from blue light LED light source, the colour temperature is lower relatively this moment, but the colour temperature is general more than 9000K, the colour temperature is the light bluish more than 9000K, directly see through the glass apron outgoing and can cause the damage to the human body, however, print this on the glass apron of display screen and prevent blue light printing ink, just can effectual reduction emergent light's colour temperature, make the colour temperature reduce to below 7000K, the blue light is directly filtered to the glass apron, thereby avoided because the blue light filters out the damage that causes eyes.
