Description
Technical field
The present invention relates to a kind of toner and preparation method thereof and using method, particularly relate to a kind of blue light solidification toner and preparation method thereof and curing.
Background technology
Laser printer is a kind of conventional computer peripheral equipment, it is radiated in the photosensitive drums of charging by laser and writes electrostatic latent image, then attract charged toner-particle to form image, then be transferred on print media, imaged on print media by heating/pressurizing/fixing.Because laser printing has speed soon, noise is little, image waterproof, and single page low cost and other advantages, usable range is more and more wider.Needed for early stage toner, fixing temperature is higher, needs to carry out preheating to warm-up mill in advance, and not only need a large amount of energy consumptions, print speed is also restricted.
In order to solve the problem, some toner adopts the material of low softening temperature to make, although can improve print speed and save fixing energy, causes it easily to lump because softening temperature is low, gives transport, storage and use to bring inconvenience; In addition, the demand of some particular surroundingss to performances such as high temperature resistant, antifriction scrape along resistances cannot also be met.
In order to save fixing energy consumption and improve print speed, publication number be US20110177450A1 patent document discloses a kind of fixation method, namely on unfixed toner image, spray one deck light-cured resin, by the LED light irradiation of 360-420nm, cured resin solidified and reach fixing; Although this mode no longer needs traditional heating/pressurizing/fixing, save corresponding energy and improve print speed, the equipment spraying resin be needed as auxiliary, add the complicacy of printer.
In order to improve the antifriction scrape along resistance to elevated temperatures of toner, the patent No. is that the patent documentation of US8455166 gives a kind of ultraviolet light polymerization toner and preparation method thereof, include UV-cured resin, ultraviolet initiator and wax in this toner, it adopts mechanical crushing method to be prepared.In addition, be give a kind of method preparing ultraviolet light polymerization toner in the patent documentation of US7494755B2 in the patent No., namely the emulsion of macromolecule resin particle is formed by monomer polymerization, form ultraviolet light polymerization toner with the emulsion containing unsaturated polyester by the mode such as heating, the toner of preparation like this can be applied on the materials such as flexible package.
Because ultraviolet light photons energy is high, so curing rate is fast, but the ozone produced in print procedure can damage equipment and human body, and in addition, if ultraviolet light directly shines human body, meeting injured skin, makes eyes sore.In addition, use the printer of this toner to need that mercury ultraviolet lamp is installed in the machine and steep for program curing provides ultraviolet light, but this light fixture there is the shortcoming that power input is large and output power is little, produces a large amount of heat-energy losses, makes fixing consume energy on the contrary large.
Compared with ultraviolet light, the energy of single blue photons is much lower, is not easy the solidification causing unsaturated polyester, easily occurs the incomplete phenomenon of solidification, causes printing effect unstable, at present also not used for the blue light solidification toner that practicality prints.In addition, blue light is visible ray, can not have an impact to human body, equipment and environment, and LED array can be adopted to produce, and has electric energy conversion rate high, and the advantage such as consume energy low.
If the toner used in printer has eutectic characteristic, and after fixing, there is excellent rub resistance, high temperature resistant and mechanical property, then can improve print speed and while reducing fixing energy consumption, improve usable range and the print quality of toner; If toner can adopt blue light to solidify completely, then can save printing energy consumption, and improve the range of application of light curable type toner.
