Description
Technical field
The utility model belongs to mobile phone screen print field, is related to a kind of without base material Mobile phone screen patch material.
Background technology
With the popularization of plane smart mobile phone, new trend side of the increasing manufacturer using Curved screen as smart mobile phone
To external screen of producer's generally use bend glass as smart mobile phone, in its manufacturing process, being usually directed to bend glass screen
The process of upper printing-ink, due to the surface modeling of glass, add printing difficulty.In the prior art, general line is by photosensitive oil
Ink, which is transferred on glass rupture pressure disc, forms ink layer, then carries out photocuring processing, then OCA pressure sensitive adhesives will be coated with ink layer
Layer, makes rupture pressure disc be bonded with bend glass screen by OCA pressure-sensitive adhesive layers；But the thickness increase of finished product being present, OCA is pressure-sensitive cementing
It is low with joint efforts, paste the problem of not firm enough.
Utility model content
The utility model main purpose is to propose that one kind pastes material without base material Mobile phone screen, it is intended to solves in the prior art,
Mobile phone curve screens ink transfers, and finished product thickness is big, and OCA pressure sensitive adhesive adhesions are low, pastes the problem of not firm enough.
In order to solve the above-mentioned technical problem, material is pasted without base material Mobile phone screen the utility model proposes one kind, including from up to
Under the first mould release membrance, OCA pressure-sensitive adhesive layers, ink layer and the second mould release membrance that are stacked.
Preferably, the OCA pressure-sensitive adhesive layers include the pressure-sensitive dual cure glue of OCA.
Preferably, the ink layer includes photosensitive-ink.
Preferably, it is additionally provided with micronano optical lines layer between ink layer and the OCA pressure-sensitive adhesive layer.
Preferably, first mould release membrance and the second mould release membrance include PET film and release layer.
Ink transfer is solidificated on the mobile phone screen of curved surface by the utility model by OCA pressure-sensitive adhesive layers, solves curved surface
Screen directly prints the problem of larger yield rate of difficulty is low；Simultaneously because after OCA pressure-sensitive adhesive layers and ink layer heat cure with mobile phone
Screen is combined into one, and without the protection of the second mould release membrance, reduces screen thickness.

Embodiment
In order that content of the present utility model is easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
Material is pasted without base material Mobile phone screen the utility model proposes one kind, with reference to figure 1, including the be stacked from top to bottom
One mould release membrance 10, OCA pressure-sensitive adhesive layers 20, the mould release membrance 50 of ink layer 40 and second.The utility model is by setting OCA pressure-sensitive adhesive layers
20 make it be connected with mobile phone curve screens, so as to which ink is printed on mobile phone screen, solves curve screens and directly print difficulty
Spend the problem of larger yield rate is low；The first mould release membrance 10 and the second mould release membrance 50 are used simultaneously, is pasted in OCA pressure sensitive adhesives and screen
The first mould release membrance 10 and the second mould release membrance 50 can be successively removed before and after conjunction, realizes that no base material fitting reduces the thickness of mobile phone screen.
In above-mentioned fact Example, with reference to figure 1, OCA pressure-sensitive adhesive layers 20 include the pressure-sensitive dual cure glue of OCA.OCA is pressure-sensitive dual
Solidification glue has the characteristic of UV solidifications and heat cure, and the pressure-sensitive dual cure glue of OCA is coated with the release layer of the first mould release membrance 10
Afterwards, the characteristic of its UV solidifications can be utilized to make its solidification, but OCA pressure-sensitive adhesive layers 20 now are not fully cured, and still possess
The characteristic of pressure sensitive adhesive；After OCA pressure-sensitive adhesive layers 20 are bonded with mobile phone screen, moreover it is possible to using the characteristic of its heat cure, by adding
Heat baking makes it be combined together and be fully cured with mobile phone screen and ink layer 40, and its hardness can reach 4~6 grades of (Mohs
Hardness), improve the adhesion and stability of OCA pressure-sensitive adhesive layers and mobile phone screen and ink layer 40.
In above-mentioned fact Example, with reference to figure 1, ink layer 40 includes photosensitive-ink, photosensitive-ink refer to it is sensitive to UV light,
And a kind of ink of ultraviolet curing can be passed through.The Main Ingredients and Appearance of UV curable ink includes the pre- thing of photopolymerization, photonasty
Monomer, Photoepolymerizationinitiater initiater, organic pigment and auxiliary agent etc., light trigger is a kind of easily by light activated compound in ink,
Excited after absorption illumination makes photosensitive-ink that photocuring occur as free radical, energy transfer to photonasty molecule or photocrosslinking agent
Under ultraviolet lighting, the Photoepolymerizationinitiater initiater in photosensitive-ink switchs to free state molecule after absorbing the photon of certain wavelength for reaction,
As free radical, then by the transmission of intermolecular energy, polymerizing prepolymer and photo-sensitive monomer is changed into excitation state, produce
Charge-transfer complexation body, it is complexed continuous cross-linked polymeric between body, film-forming.The solidification process of photosensitive-ink is that a photochemistry is anti-
Answer process, i.e., in the presence of UV energy, prepolymer film-forming within the extremely short time；Ultraviolet light is except causing ink
Surface cure outside, can more permeate in the ultraviolet curing ink for going deep into liquid, and stimulate the further solidification of deep layer ink film.Pass
Solidified in system ink by the ink of main foundation of oil under oxidation, and the ink based on solvent or water is main
It is to lean on the evaporation of water or solvent and solidify, part ink can penetrate into paper.Therefore, compared with traditional ink, ultraviolet cured printing
The polymerization drying of ink is more thorough, and speed is faster.
In above-mentioned fact Example, with reference to figure 1, micronano optical line is additionally provided between ink layer 40 and OCA pressure-sensitive adhesive layers 20
Road floor 30.Phenomena such as wiener optical grains layer is the reflection based on light caused by surface micro-nano structure, scattering, refraction, diffraction come
Different colors and texture are shown, plays good decoration function for mobile phone screen, exterior design change is various to be had well
Design sense.
In the above-described embodiments, PET film and release layer are included with reference to figure 1, the first mould release membrance 10 and the second mould release membrance 50.This
In embodiment, the first mould release membrance 10 and the second mould release membrance 50 include PET film and release layer, and PET film has tensile strength high, and heat is steady
It is qualitative it is good, percent thermal shrinkage is low, surfacing is bright and clean.Release layer includes silica gel, by setting the first mould release membrance 10 and second release
Film 50 is used to protect the ink layer 40 of inside and OCA pressure-sensitive adhesive layers 20 survivable, also makes ink layer 40 and OCA pressure sensitive adhesives
20 layers of layer is easier to depart from the first mould release membrance 10 and the second mould release membrance 50.
Specific embodiment above, technical problem, technical scheme and the beneficial effect solved to the utility model are carried out
It is further described, should be understood that and these are only specific embodiment of the utility model, is not limited to this
Utility model, it is all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done etc., it all should wrap
It is contained within the scope of protection of the utility model.
