Specific implementation mode
In the following, refer to the attached drawing illustrates the organosilicon blanket of embodiments of the present invention.
Organosilicon blanket 1 can be used as middle transfer body in hectographic printing, as shown in Figure 1A, have base material 2 and reality
The silicon rubber 3 of the processing of irradiating electron beam is applied.Base material 2 and silicon rubber 3 form laminated body.
Base material 2 is the component for the physical strength for improving organosilicon blanket 1.Base material 2 is formed by film.The material of film is for example
Polyethylene terephthalate (PET), polyphenylene sulfide (PPS) and polyethylene naphthalate (PEN) etc..
Silicon rubber 3 carries out the reception and transfer of ink in printing process.
As shown in Figure 1B, organosilicon blanket 1 is winding and installed in the surface of blanket cylinder 4.Specifically, with from rubber
The mode of 4 side of cloth roller lamination successively installs base material 2 and silicon rubber 3.Silicon rubber 3 forms the periphery of organosilicon blanket 1 as a result,
Part.Hereinafter, the outer peripheral portion is known as superficial layer.It should be noted that axis 10 is rotary shaft.
Here, the printing process of the hectographic printing to organosilicon blanket 1 is utilized illustrates.
First, as shown in Figure 2 A, ink I is made to be attached to version 20 with given pattern.Then, as shown in Figure 2 B, make installation
There is 4 moving in rotation of blanket cylinder of organosilicon blanket 1, and it is made to be pressed together in version 20, the ink I in version 20 is made to transfer
To the superficial layer of organosilicon blanket 1.Then, as shown in Figure 2 C, make 4 moving in rotation of blanket cylinder, and make organosilicon
Blanket 1 is pressed together on stock 30.The ink I for being attached to the superficial layer of organosilicon blanket 1 is set to be transferred to stock as a result,
30, the pattern of desired ink I is formed on stock 30.The printing process of hectographic printing is completed as a result,.In addition to this, have
Machine silicon blanket 1 can be used for conventionally known hectographic printing.
In such printing process, the ink filament rolled stock 30 in order to prevent, obtain line width and uniform film thickness,
Irradiating electron beam, illuminated portion are passed through to silicon rubber 3 obtained from the surface irradiating electron beam as the silicon rubber 3 of superficial layer
The physical property divided is modified.
As the condition to 3 irradiating electron beam of silicon rubber, by the absorbed dose of radiation of electron beam that silicon rubber 3 absorbs and make electronics
The accelerating potential of accelerate (beamacceleration) is as described below.
First, the absorbed dose of radiation that silicon rubber 3 rolls the electron beam absorbed required for stock 30 in order to prevent be 30kGy with
Upper and 2000kGy or less.
When making silicon rubber 3 absorb the electron-beam dose of the range, the crosslink density for absorbing the part of electron beam increases.
Therefore, the Young's modulus for absorbing the part of electron beam increases.Therefore, the adhesiveness of the part reduces, can in printing process
To prevent the print object 30 caused by silicon rubber volume 3 from rolling.
Stock 30 is rolled in order to prevent, and the adhesion values (adhesiveness) of silicon rubber 3 are 152gf or less.In silicon rubber 3
When adhesion values are within the scope of this, in printing process, silicon rubber 3 will not roll stock 30.
In addition, the adhesion values of silicon rubber 3 can be such as 151gf or less, 140gf or less, 100gf or less, 90gf with
Under, 80gf or less, 75gf or less, 70gf or less, 69gf or less, 68gf or less, 67gf or less or 66.8 or less.In addition, silicon rubber
The adhesion values of glue 3 can be more than 0gf, 1gf or more, 3gf or more, 5.0gf or more or 5.3gf or more.
It is chatted later it should be noted that these adhesion values are the TACKINESS TESTER manufactured by RHESCA companies
The value measured under the conditions of stating.
Next, the ink filament of line width and uniform film thickness in order to obtain, the absorbent of the electron beam absorbed by silicon rubber 3
Amount is 30kGy or more and 1000kGy or less.
When making the dosage of electron beam of the absorption of silicon rubber 3 range, the crosslink density for absorbing the part of electron beam increases
Add.Therefore, the Young's modulus for absorbing the part of electron beam increases.Therefore, it reduces, subtracts in the absorbability of the part printing ink solvent
The drying of the ink on the surface of light silicon rubber 3.It, can be with as a result, when making the ink on the surface of silicon rubber 3 be transferred to stock 30
The ink filament of line width and uniform film thickness is obtained on the surface of stock 30.

Surface penetrate to desired depth, therefore preferably.Here, it is desirable to depth refer to roll in order to prevent stock 30, reduce
The absorbability of printing ink solvent and mitigate ink on 3 surface of silicon rubber drying preferred electron beam depth of shine.In addition,
The value of accelerating potential can change as needed, for example, can be 80kV or more, 90kV or more, 100kV or more, 110kV or more
Or 120kV or more, can be 140kV or less, 130kV or less or 125kV or less.It should be noted that accelerating potential can be
125kV。
It is believed that the electron beam that the reduction of the absorbability of such adhesiveness, printing ink solvent is absorbed by silicon rubber 3
Depth that dosage and electron beam are penetrated from the surface of silicon rubber 3 determines.
In addition, being increased by the crosslink density to 3 irradiating electron beam of silicon rubber, the part for absorbing electron beam of silicon rubber 3
Add, the hardness of the part increases.As a result, in printing process, by the pressing of organosilicon blanket 1 when in version 20, silicon rubber 3 is not
It is easy to cause excessive deformation because of version 20.Thus, for example, even if in the case where version 20 is intaglio plate, it is so-called to be also possible to prevent
Bottom contact (bottom work as り).
Here, the electron beam treatment with irradiation for having used electron beam illuminating device is illustrated.
Electron beam illuminating device can be to the silicon rubber irradiating electron beam conveyed with just given conveying speed V.The electronics
Beam obtains kinetic energy by being applied in voltage (accelerating potential) in electron beam illuminating device, to accelerate.Therefore, acceleration electricity
Pressure is higher, and electron beam gets over the deep that can reach silicon rubber.I.e., it is possible to by adjusting the value of accelerating potential, the place of silicon rubber is adjusted
Manage depth.
In addition, electric current (beam current) I that the flowing of the electron beam generates is bigger, the suction of the electron beam absorbed by silicon rubber
It is more to receive dosage D.The physical property of silicon rubber is determined by absorbed dose of radiation D.That is, it is considered that even if accelerating potential is different, as long as inhaling
Receipts dosage D is identical, and physical property is also identical.
In addition, as described above, repeatedly into exercise silicon rubber absorb doses electron beam processing in the case of, quilt
The dosage that single treatment is absorbed that adds up to for the absorbed dose of radiation D that silicon rubber absorbs is multiplied by number of processes (number of pass times) and obtains
Value.
It should be noted that absorbed dose of radiation D can be calculated by formula D=KI/V.Here, K is electron beam illuminating device
Intrinsic constant.
