Description

A kind of preparation method of temperature-sensitive anti-forgery ink
Technical field
The present invention relates to printing technologies, are to be related to a kind of preparation method of temperature-sensitive anti-forgery ink specifically.
Background technology
With the fast development of social economy, the economic loss caused by annual whole world personation low-quality counterfeit or inferior quality goods reaches thousands of Hundred million dollars, continuous cause legal dispute or even the accident of personal injury is caused also to happen occasionally.Especially at home, its people's warp Ji is in planned economy to the market economy transitional period, and various fake and inferior commodities seriously destroy national economy legal order. For the sound development of guarantee national economy, socialist legal system is on the one hand established and improved, while must also be checked erroneous ideas at the outset, is prevented Suffer from possible trouble.In commodity circulation, most effective protection is exactly good using concealment, specificity, security and reliability Anti-forgery ink.Temperature-sensitive anti-forgery ink is a kind of ink with thermal discoloration property, can with the variation of environment temperature and Color is rapidly changed, makes to be colored color effect of the object with dynamic change, therefore is widely used in food antifalsification label With the fields such as temperature-sensitive packaging material.
At present, in temperature-sensitive anti-forgery ink using it is more be inorganic invertibity thermochromic pigments and liquid crystal type invertibity Thermochromic pigments.In current art, most temperature-sensitive anti-forgery inks select inorganic or liquid crystal type invertibity thermochromic pigments It is prepared, the change chromatic sensitivity of this two classes invertibity thermochromic pigments is low, and stability is poor, raw, and production cost is higher, is unfavorable for Environmental protection.
Therefore, in the prior art, sensitivity is low, and stability is poor, and production cost is higher, the problems such as being unfavorable for environmental protection, if A kind of preparation method of temperature-sensitive anti-forgery ink is counted, is the current technical issues that need to address.
The content of the invention
Goal of the invention：The defects of for the prior art and deficiency, solution is low there are sensitivity, and stability is poor, production cost Higher, the problems such as being unfavorable for environmental protection, applicant improves by repeatedly practice, devises a kind of preparation side of temperature-sensitive anti-forgery ink Method.
Technical solution：In order to realize foregoing invention purpose, a kind of preparation method of temperature-sensitive anti-forgery ink, the temperature-sensitive is anti-fake Ink includes link stuff, organic toner, crosslinking agent, special anti-fake material, diluent and other auxiliary agents, wherein, by following weight The raw material composition of part：Link stuff 55-60%, organic toner 18-20%, crosslinking agent 1.5-2%, special anti-fake material 12-15% And other auxiliary agent 2-5%, the link stuff include forming with following weight parts：Natural rosin resins 10-15%, polyvinyl alcohol 5- 10%th, epoxy resin 5-8% and acrylate 25-30%；
A kind of preparation method of temperature-sensitive anti-forgery ink, comprises the following steps：
1) stock up：By 55-60% link stuffs, 18-20% organic toners, 1.5-2% crosslinking agents, special anti-fake material 12- The other auxiliary agents of 15% and 2-5% weigh standby；
2) grind：On the basis of step 1), natural rosin resins 10-15%, polyvinyl alcohol 5-10%, epoxy resin 5- 8% and acrylate 25-30% mixing be put into be ground on grinder 6-8um powder it is spare；
3) stir：On the basis of step 2), by the natural rosin resins 10-15%, polyvinyl alcohol 5-10%, ring of grinding Oxygen resin 5-8% and acrylate 25-30% mixed powders are stirred by adding in 1.5-2% crosslinking agents, emulsifier, deionized water Uniformly, mixing speed 180-200r/min obtains mixed slurry A after stirring 30min, places after 2-3h in mixed slurry A The special anti-fake materials of 12-15% and the other auxiliary agents of 2-5% are added, in stirring barrel temperature control in the range of 35-40 DEG C, stirring Mixed slurry B is obtained after 20min；
4) finished product detection, packaging, on the basis of step 3), slurry B to be mixed is packed after being detected after being cooled to room temperature.
Preferably, the crosslinking agent is boric acid aqueous solution.
Preferably, other auxiliary agents include antifoaming agent, neutralizer.
Preferably, the antifoaming agent is tributyl phosphate.
Advantageous effect：Compared with prior art, the present invention its advantage is：
1st, the present invention is the anti-forgery ink prepared by the use of polyvinyl alcohol as auxiliary link stuff, and polyvinyl alcohol asepsis environment-protecting can Degradation has good film forming, cohesion, wearability.
2nd, high sensitivity of the present invention, stability are good.
