Research And Development Of UV Offset Printing Ink For The Nonpolar Plastics

With the development of UV offset printing technology in our country, UV printing inks have been widely applied in every printing domain. Because of its quick curing velocity, low energy consumption, zero VOC. To increase the printing ink to adhere in the surface, use methods such as electronics corona punch. This topic research to solving the problems, reduces the printing working procedure, the development does not need to process accepts for printing the superficial a series of UV offset printing ink, causes it in the hardening time, to adhere to stick cohere aspects and so on fastness to meet the production requirement, uses in instructing the production.This article through to the UV offset printing ink component’s pigment and the light initiator’s spectrum analysis, discovers in the UV offset printing ink formula the pigment and the light initiator combination as well as the matching situation; Take the coherency, the mobility, the hardening time as well as adhere to stick cohere fastness as the reference standards, the optimal each kind of acrylic resin, discovers the resin the optimal fit as well as the matching situation; Carries on reasonable matching various components, with three roller grinders the printing ink degree of fineness control below15μm, optimizes through the orthogonal analysis experiment the allocated proportion, thus obtains the series printing ink best formula.The ultraviolet ray spectrum analysis result indicated that light initiator OMBB,907, EDB, ITX and369in the UV offset printing black printing ink, match the MA-11carbon black the best allocated proportion is2:7:4:1:1. Because Pope shields small as well as the extinction efficiency high reason, in the middle of colored ink formula, light initiator mainly by907primarily, auxiliary increase few other and pigment absorption light wave superposition light initiator.In the UV offset printing black printing ink compound design, some sole resins were selected to carry on each performance to the printing ink the examination, subsequently discovers mix resin the best allocated proportion. Through to the printing ink each performance’s examination, confirms us to design the formula the accuracy. In the middle of yellow, red, blue tricolor printing ink series, the experiment selects the resin total quantity is65%, and according to AK624:AK6182:7166is3:4:6allocated proportion manufacture printing ink. Through printing ink curing velocity, adheres to stick cohere fastness as well as in accepts for printing the superficial color density, designs under the resin allocated proportion controlled condition light initiator combination.
