Description

Technical Field

[0001] The invention relates to the technical field of ink production, in particular to an antistatic ink and a preparation method thereof. Background Art

[0002] Ink is an important material used in printing. It displays patterns and texts on substrates through printing or spraying. Ink includes main ingredients and auxiliary ingredients, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. As social demand increases, the variety and output of inks also expand and grow accordingly.

[0003] When producing traditional anti-static ink, the materials are usually directly put into a blender for stirring, and then stirred evenly by the blender to form anti-static ink. During the stirring process, some materials cannot be fully stirred, resulting in impurities in the anti-static ink, which reduces the quality of the anti-static ink. For this reason, we propose an anti-static ink and a preparation method thereof to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide an antistatic ink and a preparation method thereof to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical scheme: an antistatic ink and a preparation method thereof, comprising 10-30 parts of toner, 15-50 parts of acrylic resin, 8-20 parts of conductive polymer solution, 20-30 parts of antistatic agent, 30-40 parts of water, 2-10 parts of antiwear agent, 2-8 parts of dispersant, 1-2 parts of fluorocarbon surfactant, 10-90 parts of alcohol solvent and 1-10 parts of defoaming agent;

[0006] The toner is composed of any one or more of graphite, azo pigment, phthalocyanine pigment, nitro pigment and nitroso pigment;

[0007] The anti-wear agent is ethylene-vinyl acetate copolymer.

[0008] Preferably, the conductive polymer solution consists of a substrate and a conductive filler.

[0009] Preferably, the base material consists of polyethylene, polypropylene and polystyrene, and the conductive filler consists of carbon black, graphene and metal powder.

[0010] Preferably, when processing the graphite, the graphite is first cut in a sealed environment. After cutting, wait for the dust to fall naturally, then put the graphite into a sealed environment again, and push the pressing plate with a cone downward by a hydraulic telescopic rod to perform the initial crushing of the graphite. After the initial crushing of the graphite, the crushed graphite is placed in a pulverizer for secondary crushing, and then the crushed graphite particles are placed in a grinder for grinding. During the grinding process, the graphite debris and powder in the cutting, primary crushing and secondary crushing are slowly added through a funnel to obtain graphite powder, and then the graphite powder is crushed multiple times by grinders of different precisions to finally obtain graphite powder.

[0011] Preferably, the antistatic agent is obtained by mixing conductive carbon black and silver powder in a ratio of 1:10 to 15. During mixing, first put an appropriate amount of conductive carbon black into a blender, then add 1 part of silver powder, start the blender for stirring, then add 1 part of silver powder every 10 minutes until an appropriate amount of silver powder is added, and finally stir for 20 minutes, take out the stirred antistatic agent, add a screening device on the top of the blender after taking it out, put the stirred antistatic agent into the screening device, sieve the stirred antistatic agent through the screening device, and the antistatic agent after sieving evenly falls into the blender, start the blender, and stir it here through the blender. After stirring, take out the stirred antistatic agent again for sieving and stirring, and repeat sieving and stirring 3-6 times to obtain a finished antistatic agent.

[0012] Preferably, the method comprises the following steps:

[0013] Step 1: Add appropriate amounts of color powder, acrylic resin, defoamer and water into the mixer. When adding the materials into the mixer, the material guide tube contacts the lower part of the inner wall of the mixer. During the process of adding the materials, the material guide tube gradually rises, so that the materials are added into the mixer along the inner wall of the stirring ball, reducing the diffusion of the materials, making the powdered materials more stable during the addition process, and reducing the powder diffused in the air. Then, close the mixer cover, start the mixer, and mix the materials evenly through the mixer to obtain the first portion of color paste, in which 1-3 portions of water are added according to the proportion;

[0014] Step 2: Take the color paste out of the mixer, and then put the color paste into a filter device for sieving, filter out the lumps that are not fully dissolved, and then add 1-3 parts of water that were not added in step 1, mix the lumps that are not fully dissolved with an appropriate amount of water, and then sieve again to reduce the lumps in the mixed liquid, so as to prepare the second portion of color paste;

[0015] Step 3: Add the second portion of the color paste in step 2 to the color paste in step 1 and mix;

[0016] Step 4: Slowly add the color paste into the grinder, start the grinder, and grind the raw materials in the color paste through the grinder. During the grinding process, slowly add 1-3 parts of water in portions to further reduce the solid impurities in the color paste;

[0017] Step 5: After the grinding is completed, the color paste is directly fed into the stirring device, and then the heating component of the stirring device is started to heat the color paste through the heating component, and the stirring rod of the stirring device is notified to start, and the color paste is heated and stirred. During the heating and stirring process, part of the water vaporized into water vapor is discharged through the outlet valve, so that the water added in step 4 is completely discharged, thereby obtaining the color paste;

[0018] Step 6: Add the conductive polymer solution, antistatic agent, antiwear agent, dispersant, fluorocarbon surfactant and alcohol solvent into the stirring device in step 5, and then start the stirring device to stir the materials, and after stirring evenly, the antistatic ink is obtained.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By setting polyethylene, polypropylene, polystyrene, carbon black, graphene and metal powder, the ink can be made anti-static and more stable during printing. In graphite processing, the graphite is cut in a sealed environment and cut into small pieces, which can be convenient for graphite crushing. At the same time, the sealed environment can prevent the dust and fine particles of graphite from spreading during cutting, which can save materials and protect the environment and prevent workers from inhaling. After cutting, the graphite is put into the sealed environment and pushed by the hydraulic telescopic rod with cone The cone is inserted into the graphite block through the hydraulic telescopic rod to squeeze the graphite block. The cone is inserted into the graphite block to crush the graphite block. While crushing, the pressing plate presses the graphite block into small graphite pieces. The crushed graphite pieces are put into the pulverizer for secondary crushing. After that, the crushed graphite particles are put into the grinder for grinding. During the grinding process, the graphite debris and powder from the cutting, primary crushing and secondary crushing are slowly added through the funnel to grind the graphite for multiple times to make the graphite more delicate. The ink made of powder can be more delicate, so that the use effect of the ink is better. The antistatic agent is obtained by mixing conductive carbon black and silver powder in proportion. First, put an appropriate amount of conductive carbon black into the mixer, add 1 part of silver powder every 10 minutes, and continue to stir until an appropriate amount of silver powder is added. The silver powder is added in batches so that the silver powder can be fully mixed with the conductive carbon black to improve the mixing effect. The stirred antistatic agent is put into the screening device, and the stirred antistatic agent is screened by the screening device. After screening, the antistatic agent falls evenly in the mixer, and the mixer is started. The mixer is stirred here, and the stirred antistatic agent is screened, mixed and sprinkled, so that the conductive carbon black and the silver powder are fully mixed, so that the mixing effect of the antistatic agent is better. The filtered solid material is filtered twice during the production process, and then the filtered material is mixed with water and melted and added to the mixed liquid to reduce impurities in the antistatic ink and improve the printing effect of the antistatic ink. At the same time, water is added during the grinding process of the grinder to improve the grinding efficiency, and then the excess water is evaporated by the evaporator to make the antistatic ink have a better use effect.
