Description
Technical field
The present invention relates to a kind of production methods of holographic metal molding mother matrix, belong to moulding holographic technology field.
Background technique
In moulding holographic technology, most important process first is that making holographic metal is molded mother matrix, be molded producing in enormous quantities
During holographic metal mother, need first to prepare holographic metal molding mother matrix.The manufacture craft of general holography metal molding mother matrix
Process are as follows: layout → pre-treatment → conductive layer formation → electroforming → separation → metal mother, wherein layout mainly has mechanical spelling
Version and two kinds of techniques of UV layout；Pre-treatment includes cleaning, wetting, sensitization, be greasy dirt in order to remove patterned surfaces and impurity with
And patterned surfaces is ionized, guarantee that the formation of subsequent conductive layer is gone on smoothly；It is formed by way of spray silver or chemical silvering
Conductive layer；Then the electroforming metal version in electroforming tank separates metallograph and plastic base/film after the completion to get holographic metal is arrived
It is molded mother matrix.In the manufacture craft, after the completion of layout, it is necessary to carry out pre-treatment to pattern plane and form conductive layer, Cai Nengji
Continuous to carry out electroforming step, process is relatively more, restricts production efficiency；And the process of pre-treatment and formation conductive layer is to metal
The quality of mother matrix is also very crucial, often will lead to metal mother and various visual defects occurs, influences qualification rate.On the other hand, it moulds
Material basement membrane belongs to material easy to produce static electricity, when carrying out UV layout operation, due to the patch repeatedly of plastics mother matrix and plastic-based film
It closes and the roller coating of applicator roll, basement membrane and mother matrix more easily produces electrostatic, easily adsorb the impurity such as dust, carry out UV layout operation
When, UV solidify after pattern in be easy to be mixed into this miscellaneous point, cause layout visual defects, layout qualification rate is low, especially wide cut
Layout, the operating time is long, and the probability for generating such defect is bigger, and the qualification rate for risking the big version of wide cut is lower.Have in routine operation
Using a variety of antistatic measures: as spent electrostatic air gun before each layout operation and going to destatic using electrostatic air gun is removed,
It makes troubles in practical application to operation, and goes electrostatic efficiency unstable；The anti-static plastic basement membrane that directlys adopt also is used to
Layout, but after covering first layer UV pattern layer, the antistatic property of UV pattern layer surface is just again very poor, is spelling for a long time
In version operating process, in the UV pattern layer of plastic-based film and the UV pattern layer of transparent mother matrix or easy to produce static electricity, layout is influenced
Quality and layout qualification rate.
Patent of invention " a kind of UV keyline layout method of holography special edition " (201310177004.2) only discloses one kind and can be improved
The keyline layout method of precision can avoid generating bubble and gap, and the holographic dedicated small version of pattern is spliced into repeatedly is suitable for production
The big version of wide cut seamless holographic.
