A kind of stamping systems possessing low temperature printing and high temperature sterilize performance and preparation method thereof
Technical field
The invention belongs to technical field of hot stamping materials, be specifically related to a kind of possess low temperature print and high temperature sterilize performance scald
Print paper tinsel and preparation method thereof, its mark that can be used for transfusion flexible bag is printed.
Background technology
At present, the mark of domestic transfusion flexible bag is printed major part and is used hot stamping technology, but it is high generally to there is print temperature
The defect of (150 DEG C ~ 180 DEG C).Print temperature height not only causes the probability that in production process, soft bag is punched relatively big, and percent defective is high,
Energy consumption cost is the highest simultaneously.Additionally, part possess the product of low temperature printing function exist again non-refractory sterilizing (121 DEG C),
The problems such as sterilizing decolouring.
Summary of the invention
For overcoming the deficiencies in the prior art, present invention aim at providing one to possess low temperature and print and high temperature sterilize performance
Stamping systems and preparation method thereof.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of possess low temperature printing and the stamping systems of high temperature sterilize performance, tape base and the heat coating tape base opposite side surface turn
Print layer is constituted, and wherein, described thermal transfer ink layer is made up of the nanometer protective layer sequentially coating band primary surface and color layers;Described receive
Rice protective layer is made up of the raw material of following weight percentage ratio: link stuff 80 ~ 90%, auxiliary agent 10 ~ 20%.
Concrete, the link stuff in nanometer protective layer is polystyrene resin, and auxiliary agent is nano silicon.
Described color layers is made up of the raw material of following weight percentage ratio: link stuff 30 ~ 50%, pigment 30 ~ 40%, and filler 10 ~
30%.Link stuff in color layers can be softening point hypothermia thermoplastic resin between 80 ~ 100 DEG C;Filler is inorganic filling out
Material.
To account in terms of color layers total weight percent, hypothermia thermoplastic resin by acrylic resin 0 ~ 20%, rosin resin 0 ~
20% and Corvic 0 ~ 10% composition.Described inorganic filler is Pulvis Talci, calcium carbonate or barium sulfate.
Acrylic resin, rosin resin, Corvic are softening point low-temperature thermoplastic between 80 ~ 100 DEG C
Resin.Object lesson as rosin resin has: rosin glyceride, disproportionated rosin, disproportionated rosin glyceride, hydrogenated rosin, hydrogen
Change rosin glyceride, natural rosin, polymerized rosin glycerol ester, rosin pentaerythritol ester glyceride, limed rosin, maleic acid pine
Fragrant glyceride.Inorganic filler is to well known to a person skilled in the art customary filler, and the object lesson as inorganic filler has: Talcum
Powder, calcium carbonate or barium sulfate etc..
The preparation method of a kind of above-mentioned stamping systems possessing low temperature printing and high temperature sterilize performance, it comprises the steps:
A, by after the link stuff heating and melting of nanometer protective layer, be proportionally added into auxiliary agent, mix homogeneously forms protective layer ink, is coated with
Cloth, on the surface of tape base opposite side, is dried and is formed nanometer protective layer and enter into subsequent processing;
B, with the butanone of weight ratio 3 ~ 5:1 and butyl ester as mixed solvent, by each raw material of color layers (i.e. link stuff, filler and
Pigment) dilute mixing in proportion, ground make color layers ink, be coated on nanometer protective layer, dry and form color layers,
Must possess low temperature to print and the stamping systems of high temperature sterilize performance.
When preparing color layers, first butanone and butyl ester are mixed to obtain mixed solvent by the weight ratio of 3 ~ 5:1, simultaneously with fourth
Ketone and the mixed solvent of butyl ester: the mass ratio range of link stuff=8 ~ 10:1, with the mixed solvent of butanone and butyl ester by the company of color layers
Ramming material dissolves, then is proportionally added into filler and pigment, grinds and makes color layers ink, dries and forms color layers.Preferably, butanone
The temperature dissolving link stuff with the mixed solvent of butyl ester is 50 ~ 60 DEG C;After grinding, it is desirable to pigment to be uniformly dispersed, fineness is little
In 5 μm, described fineness does not comprise 0 μm;Drying temperature is 60 ~ 80 DEG C.
Base thick 12 m, nanometer protective layer thickness 1 ~ 2 m, color layers thickness 1 ~ 2 μm, the gross thickness of tape base and coating is
14~16μm.The preferred mylar of tape base, more preferably biaxial tension polyethylene terephthalate (BOPET) thin film.
The present invention possesses the stamping systems of low temperature printing and high temperature sterilize performance and is designed with nanometer protective layer and low-temperature transfer printing face
Chromatograph, prints content by hot stamping machine, and after printing, nanometer protective layer is covered in color layers surface, and therefore this stamping systems possesses low
The premium properties such as, printing content resistance to 121 DEG C high temperature sterilizes printable in 120 DEG C of low temperature, solve the most existing thermoprint
The probability that in paper tinsel product print temperature high (150 DEG C ~ 180 DEG C), production process, soft bag is punched is relatively big, percent defective is high, energy consumption cost
The problems such as height, high temperature sterilize (121 DEG C) decolouring, can be widely used for the character pattern mark on various medical transfusion soft bag surface, medicine
The printing of the information such as prison code, date of manufacture and lot number.
