Technical field
The present invention relates to PET film technical field more particularly to a kind of preparation works of the PET film for liquid crystal board
Skill.
Background technique
Now there is a kind of liquid crystal board in the market, flexible liquid crystal writing film can incude the writing pressure of lettering pen after energization
Power track, and then show corresponding written contents.
Now liquid crystal board in the market, the outer membrane of flexible liquid crystal writing film are PET basement membrane.Common PET is thin
When film is as basement membrane, have the disadvantage that: (1) surface is smooth, and it is bad to write feel；(2) there is no antiglare effect, film can be reflective,
Influence vision；(3) surface hardness is very low, is easy to scratch, not wear-resisting, influences to write and wipe；(4) do not have uvioresistant function
Can, so that the liquid crystal of bottom generates discoloration under ultraviolet (such as sunlight) irradiation, influence display effect.
Have at present by doing coating process in common PET film, to reach antiglare effect.Majority makes in coating process
It is coated with the masking liquid of addition matt particle.Due to the uniformity and diffusivity of the shape of matt particle, coating can be generated not
, surface not wear-resisting the problem of scraping.Also, these masking liquids do not have anti-ultraviolet function, and liquid crystal holds when black and white plate uses outdoors
Vulnerable to ultraviolet irradiation and influence display effect.
2- hydroxyl -4- octyloxybenzophenone is a kind of ultraviolet absorbing agent of performance brilliance, light transmittance: 350nm > 90%,
450nm > 95%, uv absorption rate: 375nm-400nm > 80%, fusing point: 47-49 oC, boiling point 457.9oC.With sub- gram in masking liquid
Based on power monomer, acrylic is macromolecule transparent material most excellent at present, and light transmittance reaches 92%, and mechanical strength is higher, is melted
About 130-140 oC of point.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of for liquid crystal board according to above-mentioned the deficiencies in the prior art
PET film preparation process, the PET film being prepared by the technique has that anti-skidding, anti-dazzle, hardness is high, wear-resisting and anti-purple
The effect of outside line is suitably applied the outer membrane of liquid crystal board.
Technical scheme is as follows:
A kind of preparation process of the PET film for liquid crystal board, step includes:
A. it configures masking liquid: by weight, 96-98% acrylic monomer, the ultraviolet absorbing agent of 1-2%, 1-2% ultraviolet light being triggered
Curing agent mixing, obtains masking liquid；
B. it is coated with: being coated using narrow slit type coating head or scraper type coating head, masking liquid is equably coated in table on PET basement membrane
Face obtains coating layer；
C. it presses anti-dazzle texture: the top and bottom of PET basement membrane being squeezed using anti-dazzle texture roller and smooth roll, extrude painting layer surface anti-
Dizzy texture；
D. photocuring: the PET basement membrane that will be covered with coating layer at the uniform velocity passes through ultraviolet radiator, and coating layer is solid after ultraviolet light irradiates
Change, obtains PET film.
Further, coating thickness 0.004-0.008mm.
Further, the surface of the anti-dazzle texture roller is provided with frosted texture, and frosted texture is by multiple protrusion surfaces
Particle composition, grain diameter 0.001-0.002mm, particle height 0.002-0.003mm, distribution of particles density are 100-
200/cm2.
Further, ultraviolet absorbing agent is 2-hydroxy-4-n-octoxybenzophenone.
Further, the ultraviolet that ultraviolet radiator issues is less than 375nm by wavelength and wavelength is greater than two kinds of wavelength of 400nm
The ultraviolet of range forms.
Further, PET film is made of the coating layer of PET basement membrane and PET membrane surface, and painting layer surface is provided with anti-
Dizzy texture, anti-dazzle texture are frosted texture, and the total mist degree of PET film is 15-20%.Compared with prior art, the present invention has such as
It is lower the utility model has the advantages that
(1) coating layer is the polymeric layer based on acrylic monomer, so that PET film hardness (JIS5406,3H/ with higher
750G), it can prevent from scratching, improve service life；Antiglare effect not only may be implemented in anti-dazzle texture, avoids reflective, moreover it is possible to real
Existing antiskid effect and abrasion resistant effect, improve and write feel；Coating layer contains ultraviolet absorbing agent, can be realized uvioresistant effect
Fruit, so that damage of the liquid crystal from ultraviolet light can be also effectively protected in outdoor application to prolong the service life in black and white plate.
(2) 2-hydroxy-4-n-octoxybenzophenone fusing point is low, and boiling point is higher, low volatility and the matching of acrylic monomer
And amalgamation is outstanding, can be diffused into coating layer well.
(3) 2-hydroxy-4-n-octoxybenzophenone has stronger absorptivity to the ultraviolet light of wavelength 375nm-400nm；
The wavelength that ultraviolet radiator issues avoids this section of wavelength of 375nm-400nm, and it is bad to avoid solidification.
(4) resolidification obtains after anti-dazzle texture is gone out by anti-dazzle texture roll-in, so that anti-dazzle grain distribution is uniform, and processes
It is convenient；Meanwhile coating layer is the hardness that can be improved anti-dazzle texture when acrylic layer, improves wearability, avoids anti-dazzle texture quilt
It polishes.
