Description
Technical field
The present invention relates to a kind of UV cured resin coatings for protecting smart television meeting liquid crystal display.
Background technique
Liquid crystal display is the display equipment of planar ultra-thin, it is made of a certain number of colored or monochrome pixels, is placed
In front of light source or reflecting surface.Its cardinal principle is to generate point, line, surface cooperation back fluorescent tube with electric current stimulation liquid crystal molecule
Constitute picture.Smart television meeting is very low with liquid crystal display power consumption, therefore is favored by engineer, suitable for using battery
Electronic equipment.
In recent years, LCD technology and product are quickly grown, and smart television meeting liquid crystal display has become letter
The important component of breath industry.Smart television meeting mostly uses transparent synthesis high molecular material with liquid crystal display, such as: PC
(polycarbonate), PMMA(polymethyl methacrylate), PET(polyester) etc..It will cause drawing for surface in actual application
Wound, abrasion, conventional method are to coat one layer of colorless and transparent paint on surface, to improve the hardness, wear-resisting, anti-scratch etc. on surface
The performance of aspect has the function that protect surface.But the skin of paint on one side surface is easy to fall off, it cannot for a long time effectively
Protect basis material in ground；On the other hand, the coating and drying of skin of paint make the production of display screen become cumbersome, to increase life
Produce cost.
Ultraviolet light solidify (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, but also the energy can also be saved compared with heat curing coating.Currently, it is not only in timber, gold
Category, paper, is widely applied on leather plastics, but also on the materials such as optical fiber, printed wiring board, electronic component encapsulation at
Function application.But conventional ultraviolet curable coating hardness is poor, thus not rub resistance, easily scratch.
Summary of the invention
The purpose of the present invention is to solve defect existing in the prior art, provide that a kind of hardness is high, is suitable for intelligence
The UV of video conference liquid crystal display is coating material solidified.
In order to achieve the above object, the present invention provides a kind of smart television meeting liquid crystal display UV solidified resins
Coating, the component including following weight proportion: 50-75 parts of UV-cured resin, 30-65 parts of solvent, photoinitiator 0.5-2

Auxiliary agent includes defoaming agent and levelling agent；Defoaming agent accounts for the 0.5%-1% of UV cured resin coating total weight；Levelling agent accounts for
The 1%-1.5% of UV cured resin coating total weight.
Wherein, defoaming agent preferred, polyethers modified silicon；Levelling agent preferred acrylate class levelling agent.Solvent is using organic molten
The mixed solvent that agent, preferably toluene and methyl proxitol are mixed with mass ratio 1:1.The preferred 1- hydroxy-cyclohexyl benzene of photoinitiator
Ketone.
The weight proportion of UV cured resin coating preferred ingredient of the present invention are as follows: 70 parts of UV-cured resin, 45 parts of solvent,
1 part of photoinitiator, 1 part of defoaming agent, 1 part of levelling agent；UV-cured resin include high-functionality polyurethane acrylic resin, in
Degree of functionality polyurethane acrylic resin and Silicone-Modified Acrylate Resin；High-functionality polyurethane acrylic resin, middle official
The weight ratio of energy degree polyurethane acrylic resin and Silicone-Modified Acrylate Resin is 2:4:1.
The present invention also provides the preparation methods of above-mentioned UV cured resin coating, it is characterised in that: is divided into the solvent
Three parts, a part of solvent addition UV-cured resin, which is uniformly mixed, obtains resin component slurries, and another part solvent adds
Enter photoinitiator and be uniformly mixed to obtain the solution containing photoinitiator, remainder solvent, which is uniformly mixed to obtain with auxiliary agent, contains auxiliary agent
Solution, by resin component slurries, the solution containing photoinitiator and the solution containing auxiliary agent be uniformly mixed up to the UV solidify
Cold coating.
The present invention is had the advantage that compared with prior art through the optimum ratio to ultraviolet-curing resin, is preferably mentioned
The high hardness of the formed coating of UV cured resin coating.The bubble in coating is reduced using defoaming agent, is improved using levelling agent
The flow leveling of film layer, increases the smoothness and feel of film layer after paint solidification.Simultaneously during the preparation process, in batches molten
Solution, more sufficiently.Smart television meeting liquid crystal display transparent substrate surface is coated in using coating of the present invention, is solidified through UV
The coating scratch resistance capability formed afterwards is strong, hardness is high, and wear-resisting property is good.
