Problems solved by technology

[0002] The commercially available toner particle size is micron level, as the particle size increases, the resolution of the printed matter will decrease, the image will be rough and blurred, and the reduction ratio of the text will be limited
In addition, there is a considerable proportion of non-soft magnetic powder in some products, which cannot be sucked up by the magnetic stick. Any toner that cannot be sucked up cannot be used, resulting in waste
In addition, there are no fluorescent and two-color toners on the market, so that anti-counterfeiting prints cannot be printed
Although color inks can print exquisite color images, their solvent polyols are soluble in water, causing color prints printed on plain paper to become blurred when exposed to water, and commercially available toners soften and stick (fixing) High, high energy consumption during use, and limits the fixing speed

Embodiment 1

[0010] Embodiment 1 blue toner production technology, nano-SiO 2 The agglomerates were broken up by ultrasonic vibration, and the figure 1 The feeding port 1 is added to the screw feeder 2, and Fe(CO) is fed through the feeding port 11 5 , to control the SiO 2 with Fe(CO) 5 The feed ratio and T 1 The temperature is 160±50℃, so that Fe(CO) 5 decomposed into Fe wrapped in SiO 2 In addition, without forming Fe particles, the outlet of the screw feeder 2 is connected to the reactor 3 preheated to 100-500°C, the temperature T3≥T2, and at the same time, water vapor is introduced through the pipe 10, and the reaction is

[0011] Fe(CO) 5 (g)=Fe(S)+5CO(g) ①

[0012] 3Fe(s)+4H 2 O(g)=Fe 3 o 4 (s)+4H 2 (g) ②

[0013] Generate package Fe 3 o 4 SiO 2 The powder is reacted to generate H 2 and CO into collector 4, H 2 and CO are taken out by the vacuum pump 5 and recycled, and the powder collected by the collector 4 is magnetically separated, and there is no soft magnetic S...

Embodiment 3

[0018] Embodiment 3 yellow toner production technology, figure 1 In the process, the ultrasonically dispersed nano-TiN is added to the screw feeder 2 with the temperature set at 100-200°C through the feeding port 1, and Fe(CO) is fed through the tube 11 at the same time. 5 (g), the other end of the screw feeder 2 is connected to the reactor 3 whose temperature is set at 100~~500° C. The Fe generated by the decomposition of the carbonyl compound is wrapped outside the TiN, and then reacts with the air entering through the pipe 10 to make the Fe Generating r-Fe 2 o 3 , the solids are reacted to generate CO and H 2 into collector 4, CO and H 2 Taken away by vacuum pump 5. The powder taken out from the valve 8 under the collector 4 is magnetically separated, the non-magnetic powder is reworked, and the magnetic powder is added with AS (or L 4G) In the epsilon-caprolactone of naphthol and the styrene containing GC (or RC) chromophore and initiator, add the water containing acc...

Embodiment 4

[0019] Embodiment 4 black toner production technology: in figure 2 In the process, mineral oil or unsaturated hydrocarbons are added from the feed port 2, and are brought into the reaction kettle 3 at 100-500 ° C with the air added from the pipe 1 and the carbon black is incompletely burned, and passed through the pipe 7 feed Fe(CO) 5 (g) and H 2 O(g), Fe(CO) 5 (g) Decompose first to form Fe, wrap it in carbon, and then react with water to form Fe 3 o 4 , the other end of the reactor 3 receives the collector 4 and collects the Fe 3 o 4 After magnetic separation, the carbon black is mixed with styrene, ε-caprolactone (or its oligomers), and initiator, and then added to the water containing the accelerator. Feed ratio is Fe 3 o 4 Carbon black: ε-caprolactone: styrene: initiator: accelerator: water = 1: 0.2~2: 0.2~2: 0.002~0.2: 0.001~0.1: 2~4 (w / w). Suspension polymerization under ultrasonic vibration and stirring for 0.5 to 4 hours, centrifuge, and dry to obtain black ...

Abstract

Disclosed is a color toner production technology for copiers and laser printers; the color of the toner has three primary colors of red, blue, yellow, and black color; the toner can change the raw materials and displays the fluorescent color; or the same powder of the toner can be displayed as two colors from different point of views; the toner of the invention can print a variety of color presswork with bright and fluorescent color and has anti-counterfeiting function; as the toner has small particle size, small inner layer proportion and less using amount, the toner enables the presswork to be clearly printed and is especially suitable for printing micro-data and images; through magnetic separation technology, the semi-finished products are provided with soft (or hard) magnetic properties and can be fully utilized; the tacky (fixing) temperature is 36-38 DEG C lower than that of the current toner; moreover, the toner of the invention has low energy consumption and short fixing time, and can extend the service life of the equipment and improve the printing and copying speed, which is an ideal upgrade product for the existing toner.

Description

technical field [0001] The invention is a production process for a series of red, yellow, blue and black toners commonly used in laser printers and electrostatic copiers. The organic coating layer is modified to lower the fixing (sticky) temperature. technical background [0002] Commercially available toner has a particle size of micron. As the particle size increases, the resolution of printed matter will decrease, the image will be rough and blurred, and the reduction ratio of characters will be limited. In addition, there is a considerable proportion of non-soft magnetic powder in some products, which cannot be sucked up by the magnetic stick from below, and any toner that cannot be sucked up cannot be used, resulting in waste. In addition, there are no fluorescent and two-color toners on the market, so that anti-counterfeiting prints cannot be printed. Although color inks can print exquisite color images, their solvent polyols are soluble in water, causing color print...
