Description
Technical field
The present invention relates to a kind of anti-dazzle UV cured resin coatings for protecting LCD display.
Background technology
LCD (Liquid Crystal Display) LCDs, it is the display device of planar ultra-thin, it is by certain
Colour or the monochrome pixels composition of quantity, are positioned in front of light source or reflecting surface.Its cardinal principle is to stimulate liquid with electric current
Brilliant molecule produces point, line, surface and coordinates back fluorescent tube to form picture.LCD display power consumption is very low, therefore is favored by engineer,
It is suitable for use with the electronic equipment of battery.
In recent years, LCD Display Techniques and production development are rapid, and LCD display has become the important composition of information industry
Part.LCD display uses transparent synthesis high polymer material more, such as：PC（Makrolon）、PMMA（Poly-methyl methacrylate
Ester）、PET（Polyester）Deng.Scuffing, the abrasion on surface can be caused in actual application, conventional method is to coat one on surface
The paint of layer water white transparency, to improve the performance of the hardness on surface, wear-resisting, anti-scratch etc., have the function that to protect surface.
But the skin of paint on one side surface easily comes off, it is impossible to effectively protects matrix material for a long time；On the other hand, skin of paint
Coating and drying the making of display screen is become cumbersome, so as to add production cost.
Ultraviolet light solidifies（UV solidifies）Coating be the 1960s exploitation a kind of environment-friendly and energy-efficient coating, the seventies I
State starts to set foot in the technical field, and tremendous development is just obtained after the nineties.Ultraviolet-curing paint is under ultraviolet light
Rapid curing, not only curing rate is fast, and the energy can also be saved compared with heat curing coating.At present, it is not only in timber, gold
Category, plastics, paper, widely apply on leather, but also on the materials such as optical fiber, printed substrate, electronic component encapsulation into
Work(application.But conventional ultraviolet curable coating hardness is poor, thus not rub resistance, easily scratch.
Strong light caused by the strong light of the surrounding of LCD display outer surface reflection simultaneously or inside injects human eye, easily causes thorn
Eye is fuzzy, clearly display screen content, this phenomenon can not be referred to as dazzle.Therefore it provides a kind of have anti-dazzle and resist simultaneously
The UV cured resin coatings of scratch performance, turn into the emphasis of existing research.
The content of the invention
The invention aims to solve defect present in prior art, there is provided a kind of hardness is high, anti-dazzle, is applicable
It is coating material solidified in the UV of LCD display.
In order to achieve the above object, the invention provides a kind of LCD display with anti-dazzle UV cured resin coatings, including with
The component of lower weight proportion：UV-cured resin 50-75 parts, solvent 30-65 parts, light trigger 0.5-2 parts, anti-dazzle particle
0.2-0.5 parts, auxiliary agent 1-3 parts；UV-cured resin includes high-functionality polyurethane acrylic resin, middle degree of functionality polyurethane
Acrylic resin and Silicone-Modified Acrylate Resin；High-functionality polyurethane acrylic resin, middle degree of functionality polyurethane third
The weight of olefin(e) acid resin and Silicone-Modified Acrylate Resin ratio is 2-3:3-4:1.
Wherein, anti-dazzle particle includes nano silicon and organic fine particles；The quality of nano silicon and organic fine particles
Than for 1:1.
The preferred polystyrene resin particulate of organic fine particles, particle size are 1-6 μm.
Auxiliary agent includes defoamer, dispersant and levelling agent；Defoamer accounts for the 0.5%-1% of cold coating gross weight；Dispersant
