Embodiment 1

[0020] Embodiment 1 prepares black ink

[0021] Add 65 grams of solvent ethanol; 5 grams of butanol; 5 grams of propanol into the heating tank 1 in turn, and then put 2 grams of vinyl resin copolymer; After being dissolved into a colloid, 7 grams of Lithol Scarlet; 1.5 grams of wetting and dispersing agent sodium methylene bis-naphthalene sulfonate; 1.5 grams of electrically neutral salt synthesized from polycarboxylic acid and amine derivatives; 2 grams of emulsifier Tween 2 grams of Span; 4 grams of stripping agent polypropylene glycol; 3 grams of polyethylene glycol, fully stir, when the temperature is heated to 65 degrees, keep for 1 hour, after the various components are completely dissolved, naturally drop to normal temperature, and then Transport it to the colloid mill 2 for circular grinding, release it when the particle size is less than 10 microns, filter through the filter 3, and clean it for filling to become a finished product.

Embodiment 2

[0022] Embodiment 2 prepares red printing ink

[0023] Add 65 grams of solvent ethanol; 5 grams of butanol; 5 grams of propanol into the heating tank 1 in turn, and then put 2 grams of vinyl resin copolymer; After being dissolved into a colloid, 7 grams of Lithol Scarlet; 1.5 grams of wetting and dispersing agent sodium methylene bis-naphthalene sulfonate; 1.5 grams of electrically neutral salt synthesized from polycarboxylic acid and amine derivatives; 2 grams of emulsifier Tween 2 grams of Span; 4 grams of stripping agent polypropylene glycol; 3 grams of polyethylene glycol, fully stir, when the temperature is heated to 65 degrees, keep for 1 hour, after the various components are completely dissolved, naturally drop to normal temperature, and then Transport it to the colloid mill 2 for circular grinding, release it when the particle size is less than 10 microns, filter through the filter 3, and clean it for filling to become a finished product.

Embodiment 3

[0024] Embodiment 3 prepares blue ink

[0025] Add 40 grams of solvent ethanol; 10 grams of butanol; 10 grams of propanol to heating tank 1 in turn, then add 3 grams of vinyl resin copolymer; 1 gram of polyvinyl pyrrolidone; keep stirring until it is fully dissolved into a colloid 13 grams of phthalocyanine blue; 3 grams of wetting and dispersing agent sodium methylene bis-naphthalene sulfonate; 1 gram of electrically neutral salt synthesized from polycarboxylic acid and amine derivatives; 3 grams of emulsifier Tween; 2 grams of Span; 6 grams of polypropylene glycol; 8 grams of polyethylene glycol, fully stirred, when the temperature was heated to 65 degrees, kept for 1 hour, after the various ingredients were completely dissolved, naturally dropped to normal temperature, and then transported to the colloid mill 2 for Circular grinding, release when the particle size is less than 10 microns, filter through the filter 3, and then clean and fill to become the finished product.

Abstract

The invention relates to a component of ink and a preparation method thereof, which is mainly applicable to a special ink assorted with the surfaces of waterproof materials like erasable paper and plastics, etc. Specific components of erasable viscous ink consist of organic solvent, pigment, resin, moistening dispersant, emulsifier, and release agent, wherein, the organic solvent accounts for 60-90 percent in the overall quality of the ink; the pigment accounts for 3-13 percent in the overall quality of the ink; the moistening dispersant accounts for 0.4-4 percent in the overall quality of the ink; the resin accounts for 1.4-4 percent in the overall quality of the ink; the emulsifier accounts for 0.2-5 percent in the overall quality of the ink; the release agent accounts for 5-14 percent in the overall quality of the ink. The component of ink can be applied to writing, drawing, picture (word) spraying, and printing on erasable paper and plastic products; after being applied to writing, drawing, picture (word) spraying, and printing, the ink can not easily drop off, and can be erased with a little force by wiping materials like a soft cloth or a scrubber, etc.

Description

technical field [0001] The invention relates to an ink composition and a preparation method thereof, in particular to a rewritable viscous ink and a preparation method thereof, and is mainly a special supporting ink for the surface of rewritable paper, plastic and other impermeable objects. Background technique [0002] At present, a kind of paper and plastic products that can be used repeatedly in the market require writing, drawing, spraying (words) and ink printed on it not to fall off easily, and can be wiped with a little force with soft rags, scrub brushes, etc. remove. Use ordinary ink to write, draw, spray pictures (words) and print on this special rewritable paper and plastic products. The ink pollution on the wiper cannot achieve its purpose and effect; the whiteboard markers currently on the market are stacked together after writing on it, or are rubbed by other objects, the ink is prone to fall off, and it cannot reach its use. purpose and effect.
