Description

Technical Field

[0001] The invention relates to the technical field of printing consumables, in particular to odorless ink for printers. Background Art

[0002] In the prior art, there are two types of inkjet inks on the market: one is pigment-based inkjet ink; the other is dye-based inkjet ink; the difference between pigment-based inkjet ink and dye-based inkjet ink is that the advantages of pigment-based inkjet ink are that it is waterproof and sun-resistant outdoors, and the printed images are saturated and bright in color, with a strong texture, and are mainly used for printing outdoor advertising images. The advantages of dye-based inkjet ink are good in restoring the true color of the image and high precision, but the disadvantages of dye-based inkjet ink are that it is not waterproof, not sun-resistant, and it is not easy to preserve the image for a long time, so it is suitable for the production of indoor images. Dye-based inkjet ink can only be relatively perfect and popularized and applied if it is sun-resistant.

[0003] The existing digital inkjet inks on the market generally contain 10% to 15% cyclohexanone (CYC) to ensure the smoothness of ink printing and improve the solubility of resin. Since the solvent contains ketone, it has a very pungent smell and cannot be used in a small and closed space. Long-term use is also harmful to the human body. In addition, 72% to 87% ethylene glycol butyl ether acetate (EBA) is used. Although the smell is smaller than cyclohexanone (CYC), it still has a noticeable smell. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide an environmentally friendly and odorless ink.

[0005] In order to solve the above problems, the technical solution of the present invention is: odorless ink for printers, including colorants, solvents, surfactants, heat preservation agents, viscosity regulators, antibacterial agents, dispersants, thickeners and pH regulators, wherein the moisturizing agent is diethylene glycol diethyl ether, and the remaining ingredients are as follows by weight percentage: diethylene glycol diethyl ether 72% to 87%, diethanol dimethyl ether 8% to 15%, organic pigments 2% to 5%, and chlorovinyl resins 3% to 8%.

[0006] Further, a. mixing: diethylene glycol diethyl ether, diethylene dimethyl ether, an organic pigment and a chloroacetic acid resin are mixed in proportion;

[0007] b. Grinding: Grinding the mixture obtained in step a to form a concentrated slurry of 100 to 300 nm level;

[0008] c. Preparation: The concentrated slurry obtained in step b is prepared into ink with diethylene glycol diethyl ether and diethylene glycol dimethyl ether;

[0009] d. Filtration: Filter the ink prepared in step c to obtain odorless ink for inkjet printing.

[0010] The advantages of the present invention compared with the prior art are:

[0011] The present invention provides odorless and environmentally friendly diethanol dimethyl ether and diethylene glycol diethyl ether to replace cyclohexanone (CYC) and ethylene glycol butyl ether acetate (EBA) two solvents respectively, adopts a special process to improve the solubility, and prepares an environmentally friendly, odorless, waterproof and sun-resistant ink without reducing the smoothness of ink printing and the solubility of resin.
