Description

A kind of double lamps solidification white UV ink-jet ink and preparation method thereof
Technical field
The invention belongs to inkjet printings and printing technology, and in particular to a kind of double lamps solidification white UV ink-jet inks and Preparation method.
Background technique
In inkjet printing and printing, small ink fluid drop is directly injected to by black body surface face, printing and printing It equipment and is not physically contacted by between black body, this printing and printing equipment electronically store printed data, and It controls a device and is ejected into ink jet ink water droplet by Mo Tishang with image mode.Ink-jet ink is inkjet printing and prints not The component part that can lack, be divided into according to drying mechanism it is water base, drying mechanism be related to absorb, infiltration and evaporation；Oil base, It, which is dried, is related to absorbing and permeate；Solvent base, drying mechanism relate generally to evaporate；Heat fusing or phase transformation, wherein ink is spraying It is liquid at a temperature of penetrating, and is at room temperature solid, drying is replaced by solidification；UV solidification, is replaced by polymerization It is dry.
UV solidification is photochemistry, and UV light energy is absorbed by photoinitiator in UV ink adhesive, causes liquid Activated monomer or oligomerization combinate form reticulate the process of solid-state macromolecular, and UV photo-curing ink-jet ink has voc zero-emission, low Energy consumption, it is environmentally protective the advantages that, be suitable for a variety of stocks, ink-jet ink is not dried before UV illumination, will not be generated because of ink The phenomenon that solvent volatilizees and blocks spray head, while UV inkjet printing is due to print on demand, high speed, high quality, low cost The advantages of, increasingly have been favored by people.
Can cause the cured ultraviolet source of UV is mercury lamp in early days, and high pressure or low pressure mercury lamp, cold-cathode tube etc. emit light wave Length is all band UVA, UVB and UVC:UVA: 400nm to 320 nm；UV-B:320 nm to 290 nm；UVC:290 nm To 100 nm, in irradiation solidification process, only wherein least a portion of transmitting light can be inhaled by photoinitiator or photoinitiator system It receives, this light source ineffective radiation accounts for 75%, and wherein most is the infrared light of high-energy, generates a large amount of heat and controls production Have an adverse effect, while containing heavy metal in lamp, it is also unfavorable to safety and environmental protection.
Ultraviolet source UVLED light source is gradually matured in recent years, and UVLED light source has multinomial excellent compared with mercury lamp Gesture, first radiation efficiency greatly improve, and luminous energy effective rate of utilization improves 1 times or more；It can booting close, without preheating；Use the longevity Life length.But with mercury lamp, there are also differences, and the wavelength emission peak of UV-led light source transmitting first is single, common UVLED light source For wavelength in 395nm, wave-length coverage is narrow, at the same compare with mercury lamp power and irradiate it is low, to the light-initiated body of matching used ink System has different requirements, exists simultaneously in view of two kinds of light sources of existing market, ink can meet use under two light sources It is required that necessary.
Conventional method in white pattern production process is that ink is not stayed using white substrate, and transparent and dark substrate applies white paint The methods of realize, hardly possible attachment substrate is also needed to handle substrate, and complex process increases cost, reduces production capacity.It is existing Have to have been realized in technology and carry chalk system, some or double blank ink system on ink-jet apparatus, considerably increases ink-jet Speed.In software aspects, realizes chalk and color ink while controlling, form the image of needs, improve efficiency.It can be realized work The correct color of needs can be obtained on non-white substrate for white substrate；One layer of chalk is printed in white substrate, it can Increase the anaglyph of pattern；White inkjet ink can be advantageously utilised in transparent substrates contrast to enhance colored ink and Vividness, so-called " surface printing " or " back up " to form reflected image on a transparent substrate, in surface printing, White background is formed on a transparent substrate using white ink, and further prints color image on it, is then beaten from printing The final image that the observation of print front is formed.Overleaf in printing, color image is formed on a transparent substrate using colored ink, with White ink is applied on colored ink afterwards, and observes finally formed image through transparent substrates.White ink is still at present New application is being continually developed, is expanding to different substrates, different technique identifies the application of aspect, by application field from wide It accuses decoration industry and expands to packaging market.
The white pigment of white ink has high reflectivity, and the light efficiency of absorption is relatively low, influences solidification rate, to drawing The requirement of hair system is relatively high, since the presence of known oxygen inhibition has more serious UVLED light source than mercury lamp light source Oxygen inhibition performance, therefore chalk LED solidify ink be easy to produce apparently glue phenomenon.
The white pigment of white ink belongs to inorganic pigment, and specific gravity is bigger, and in order to reach preferable covering effect, Partial size cannot be done too low, but partial size is too big, and pigment is easy sedimentation, and hardly possible is dispersed into stable system, while same reason, The partial size of pigment is big, and the film hardness of formation is big, is easy embrittlement, cracking is easy when doing embossing pattern, while attached with substrate Property it is bad, surface printing and be easy when back up that cracking is removed or be easy from bottom in the application of white ink, it is desirable that White ink has certain flexibility and adhesion property.
