The invention provides a kind of blooming cold coating, comprise the first component, second component, levelling agent antistatic additive, light trigger, diluent, the quality of described first component and second component is 1:3～1:1 than scope；Described first component in the first oligomer, the second oligomer and monomer arbitrarily both, described second component is to select remaining component after both in the first component, the present invention utilizes the compatibility difference between opposed polarity resin or resin and monomer, form the on-plane surface micro structure of particle-like effect on coated article surface after solidification, thus reach anti-stick, atomization, anti-scratch, the effect of delustring.
Description
Technical field:
The present invention relates to blooming cold coating, be specifically related to component and the application of blooming cold coating.
Background technology:
The method generally using chemosynthesis from matting resin the most on the market, i.e. introduces energy in coating building-up process
Light-absorbing structure or group play photoextinction.Chinese patent CN103163571A discloses a kind of blooming and system thereof
Make method, first manufacturing the mould with wavy pattern, more described mould is transferred on basement membrane, making described blooming have one
Determine mist degree；Chinese patent CN103740250A discloses a kind of preparation method from extinction type leather waterborne polyurethane coating agent,
First it is respectively synthesized A, B two component, remixes formulated；Chinese patent CN104530328A discloses a kind of from matting resin
Preparation method, first the synthesis Ludox containing double bond, is synthesized with methacrylate-based monomer with this Ludox the most again
From matting resin.Common problem existing for above patent is that method is relatively cumbersome, Expenses Cost.
It is little low with operation voltage etc. that liquid crystal display (liquid crystal display, LCD) has light weight, volume
Advantage, has been widely used in personal mobile communication and household appliances in recent years, owing to liquid crystal panel itself is the most luminous, so
Need to add backlight module, and general backlight film group includes: light source, light guide plate, optical diffusion film and prismatic lens, wherein light diffusion
Film merit can be that the point source of light emitting diode (light emitting diode, LED) is converted into uniform area source.
For the optical diffusion film in back lighting device, both require that there is good covering effect, it is also desirable to have good increasing
Bright effect.In order to meet requirements above, a lot of diffusion barrier manufacturing firms all resins or microgranule to diffusion layer are improved, but
Because the luminance raising for back lighting device is limited, so current back lighting device the most all includes prismatic lens, so pass through
Being applied in combination of prismatic lens and diffusion barrier both can solve covering problem and can also solve blast problem.
But, for back lighting device, when overlapping optical diffusion film, prismatic lens, light guide plate, the light diffusion layer of optical diffusion film and
Between prismatic lens back or front, the anti-stick layer of optical diffusion film and light guide plate surface, between prismatic lens front or light diffusion layer
Produce friction because contacting mutually, all can produce because contacting with making in transportation it addition, use in optical diffusion film superposition
Friction, either diffusion barrier diffusion layer or anti-stick layer, the positive back side of prismatic lens or light guide plate has scuffing, the most high-precision
In the liquid crystal display of refinement, its slight scratch will become the poor prognostic cause of liquid crystal display.
The existing optical diffusion film used in the back lighting device of liquid crystal display etc., typically by being just coated with light diffusion layer, base
Material (PET) and the back of the body are coated with anti-stick layer composition, and existing technology is mostly to be respectively coated with difference at PET basement membrane front and back
The resin of the diffusion particle of particle diameter.
Summary of the invention:
The purpose of the present invention is on the one hand, it is provided that a kind of blooming cold coating, solves coating and is not required to add the feelings of particle
Anti-stick is realized under condition, atomization, anti-scratch, the effect of delustring.
On the other hand, it is provided that the application of blooming cold coating.
For achieving the above object, the technical scheme is that
A kind of blooming cold coating, it is characterised in that comprise following components:
First component
Second component
Levelling agent
Antistatic additive
Light trigger
Diluent；
The quality of described first component and second component is 1:3～1:1 than scope；
Described first component in the first oligomer, the second oligomer and monomer arbitrarily both, described second component
It is that the first component is selected remaining component after both；
The most described first component is the first oligomer and the second oligomer, and the most described second component is monomer；
Described first component is the first oligomer and monomer, and the most described second component is the second oligomer；
Described first component is the second oligomer and monomer, and the most described second component is the first oligomer.
Further, and dissolubility difference DELTA SP of described first component and second component < 1, described group of the first component and
Dissolubility difference DELTA SP that two components meet is < when 1, in the micro structure size homogeneity of coated article surface formation after coating solidification
Good.
Further, the mist degree after the coating of described blooming cold coating > 3%.
Further, the surface roughness after the coating of described blooming cold coating > 0.25 μm.
Further, described first oligomer is aliphatic polyurethane dimethylacrylate.
Further, described second oligomer is aliphatic six acrylate.
Further, described monomer is that caprolactone modifies double pentaerythritol methacrylate.
Further, after the coating of described compositions, coating dry film thickness range is 2～8 μm.
Above-mentioned blooming cold coating is applied to diffusion barrier or brightness enhancement film by one.
Beneficial effect:
Present invention generally provides is a kind of blooming cold coating without particle, utilize opposed polarity resin or
Compatibility difference between resin and monomer, forms the on-plane surface micro structure of particle-like effect on coated article surface after solidification,
Thus reach anti-stick, and atomization, anti-scratch, the effect of delustring.
Detailed description of the invention:
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, to invent into
Row further describes.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to limit
