Abstract
The invention discloses a preparation method of a hole sealing solution for a printing plate material. The preparation method comprises the step of stirring and mixing sodium fluoride, phosphoric acid and deionized water to prepare the hole sealing solution. The hole sealing solution prepared on the basis of the preparation method can reduce the tension on the surface of a plate base, reduce the adsorbability and enhance the hydrophilcity and the stability of the plate surface; moreover, the hole sealing solution can meet the requirements that the hole-sealed plate base is colorless and high in corrosion resistance and wear resistance; furthermore, the hole sealing solution can participate production operation of the printing plate material at a normal temperature, so that the yield of the printing plate material is increased, and the cost is reduced.
Description
Technical field
It is with regard to a kind of printing plate more particularly the present invention relates to print the technical field of CTP plates plate processing
Use sealing of hole liquid and preparation method thereof.
Background technology
Positive-printing heat-sensitive CTP plate material needs to block anodic oxidation membrane pores before the use, is allowed to lose partly or entirely absorption
Ability, so as to improve anti-pollution, the corrosion stability ability of anode oxide film, such processing procedure is referred to as sealing pores.If not
Plus process, direct painting photosensitive liquid, the space of a whole page securely will adsorb photosensitive liquid, though this plate through exposure and development or
Washed with solvent, photosensitive liquid is remained on can not be completely disengaged from and be attracted on the space of a whole page, and blank parts are easily contaminated, carry ink,
Printing plate will be gone up dirty during printing.
Sealing pores can reduce the tension force on version base surface, reduce adsorptivity, strengthen the hydrophily and stability of the space of a whole page, together
Version base after Shi Yaoqiu sealing of holes is colourless, and with good corrosion stability and high-wearing feature.
Sealing of hole mechanism is more complicated, this is because carrying out sealing pores, its reaction speed, after sealing of hole in different medium
Aluminium plate surface color, it is all different into the medium content in micropore, hydrophily etc., in simple terms, exactly make film surface
Alundum (Al2O3) produce the crystallization water, increase volume, with blocking portion micropore.Jing after sealing pores, the volume of anode oxide film
About increase 33%.
The content of the invention
Goal of the invention：For the deficiencies in the prior art, applicant improves through repeatedly practice, devises a kind of printing plate
Use sealing of hole liquid and preparation method thereof, pore-sealing liquid prepared by the present invention effectively to reduce the tension force on version base surface, reduce adsorptivity, strengthen
The hydrophily and stability of the space of a whole page.
Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted in the present invention is：A kind of printing plate is used
Sealing of hole liquid and preparation method thereof, is stirred by sodium fluoride, phosphoric acid and deionized water and is mixed to prepare, by weight, by following components group
Into：
Sodium fluoride 4.5%
Phosphoric acid 0.8 ‰
Balance of deionized water.
Currently preferred implementation is：This product is still stirred by sodium fluoride, phosphoric acid and deionized water and is mixed to prepare,
By weight, it is composed of the following components：
Sodium fluoride 4.8%
Phosphoric acid 0.9 ‰
Balance of deionized water.
Currently preferred implementation is：This product is still stirred by sodium fluoride, phosphoric acid and deionized water and is mixed to prepare,
By weight, it is composed of the following components：
Sodium fluoride 5.0%
Phosphatase 11 .1 ‰
Balance of deionized water.
Currently preferred implementation is：This product is still stirred by sodium fluoride, phosphoric acid and deionized water and is mixed to prepare,
By weight, it is composed of the following components：
Sodium fluoride 4.9%
Phosphatase 11 .1 ‰
Balance of deionized water.
Beneficial effect：Compared with prior art, its advantage is the present invention：
1st, the present invention can reduce the tension force on version base surface, reduce adsorptivity, strengthen the hydrophily and stability of the space of a whole page, together
Version base after Shi Yaoqiu sealing of holes is colourless, and with good corrosion stability and high-wearing feature.
2nd, the pore-sealing liquid that the present invention is prepared into can at normal temperatures participate in the production operation of printing plate, increased galley
The yield rate of material, has saved cost.
