In the purpose for departing from, and then solve the problems, such as that the soft mold demoulding is difficult.
Further, it is preferable to control the surface dynes value of above-mentioned soft mold less than 30, the soft mold demoulding can have both been solved difficult
Problem, the anti-pollution characteristic of soft mold can be improved again.
In the application another kind preferred embodiment, there is provided the preparation method of soft mold, i.e., preferred above-mentioned steps S1
Including：The mixture that UV solidification glue compositions are formed is set on metal die 10；Soft base material is set on the mixture, and it is right
Soft base material carries out roll-in；Mixture after roll-in is solidified, cured layer is obtained；And removal metal die, and to solid
Changing layer carries out UV curings, obtains soft mold 20 (referring to Fig. 2).
By way of first solidifying post curing so that the hardness and surface dynes value of soft template can be controlled flexibly,
Such as control surface dyne value ＜ 30, the UV energy that preferably above-mentioned UV curings are used is 20000~100000mj/cm2.This
Outward, above-mentioned surface dynes value also advantageously improves the resistance to soiling of soft mold.On the one hand can fill mantle glue after strong UV curings
Divide reaction, and make up to hardness higher, surface texture is unlikely to deform.On the other hand can migrate auxiliary agent after strong UV curings
To surface, surface smoothness is improved, it is easy to the demoulding.
Additionally, in order to improve recoatability, beneficial to oil surface ink or other coatings, the surface dynes value of preferably decorating film is big
In 40, while the surface dynes value of the surface dynes value and above-mentioned soft template matches, the removing of soft mold is more beneficial for.Enter one
It is 10~100mj/cm to walk the UV energy that the solidification of preferred above-mentioned steps S4 uses2, modelling glue is carried out with the UV irradiation of low energy
The solidification of layer, makes the solidification of modelling adhesive tape sections, surface drying, so as to be easy to and the soft mold demoulding.Soft mold is organic material, central to have
The unreacted double bond in part, UV energy is too high to cause modelling glue-line to produce chemical reaction with soft mold surface, cause adhesive force
Enhancing, is unfavorable for the demoulding.
When the decorating film of the application needs to be applied in the environment higher to hardness requirement, preferably above-mentioned printing transferring method is also
Process including carrying out thermal maturation to decorating film.Decorating film is cured using heat energy, further improves the hardness of decorating film.
The above-mentioned formation raw material that decorating film in the prior art is may be referred to for forming the glue of decorating film, in order to adapt to this
The printing transferring method of application and the cooperation with soft mold, preferably in parts by weight, glue includes：45~70 parts of oligomer, 10~
30 parts of second comonomers, 2~8 part of second light trigger and 0~5 part of second auxiliary agent, wherein, preferably oligomer is polyurethane acroleic acid

Difference with embodiment 1 is, by 20 parts of urethane acrylate EO-2238,20 parts of urethane acrylates
6158B-80,2 parts of Si modification resin SIU2400,20 parts of monomer EM214,20 parts of monomer EM221,4 parts of initiators 184, mixing is stirred
Mix 30min and obtain master mold glue.
Comparative example 2
Difference with embodiment 1 is, by 20 parts of urethane acrylate EO-2238,10 parts of urethane acrylates
6158B-80,25 parts of Si modification resin SIU2400,10 parts of monomer EM214,10 parts of monomer EM221,4 parts of 184,1 part of initiators are helped
Agent BYK-UV3505 mixes 30min and obtains master mold glue.
The overall merit of embodiment 1~12 and the preparation process of comparative example 1~2 and decoration film properties, wherein, a dyne value is used
German arcotest dynes of pen.Line is evenly distributed, and the maximum number dyne pen for not playing any pearl point in 3 seconds is a dyne value survey
Examination, hardness is tested using pencil hardometer according to GB/T 6739-1996, and test result is referring to table 1.
Table 1
Can be seen that what is solidify to form using the UV solidification glue compositions of the application by the comparing of each embodiment and comparative example
The surface dynes value of soft mold changes with the difference of solidification energy, but, less than 30 are can be controlled in, and can be with decoration
The separation of glued membrane is easier.
In addition, the comparing according to embodiment 1,2,3,9 and 10 can be seen that carrying with the solidification energy of decoration glued membrane
Height, the hardness for decorating glued membrane is improved, but UV energy is too high that decorating film glue can be caused to be chemically reacted with decorating film surface, leads
Cause Adhesion enhancement so that the difficult increase of the demoulding, but, still there is clear superiority relative to the demoulding of comparative example.
Ratio according to embodiment 1 and embodiment 5~8 can be seen that the raising of energy is cured with soft mold, and UV is solid
The hardness for changing glue composition is improved, and decoration membrane superficial tissue is unlikely to deform, and on the other hand can migrate auxiliary agent after strong UV curings
To surface, surface smoothness is improved, it is easy to the demoulding.
Meanwhile, the contrast according to embodiment 1 and embodiment 4 can be seen that the auxiliary agent for improving surface due to eliminating, decoration
Film surface dyne value is decreased obviously, therefore can influence to decorate the recoatability of film surface.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：
The urethane acrylate oligomer of the UV solidification glue compositions comprising above-mentioned consumption and Si modification resin of the application,
Therefore, solidification causes that its surface dynes value is controllable under uv radiation, when being used as soft mold, controls its surface dynes
The difference of the surface dynes value of the decorating film for being worth and solidifying to form is larger, you can realizes the two purpose for being easy to depart from, and then solves
The difficult problem of the soft mold demoulding.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
