[0014] Preferably in the present invention, after adding the fragrance to the ink, it is necessary to stir back and forth at a rate of 25 to 30 times per minute to make the fragrance and the ink uniformly mixed.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] By adding a fragrance to the ink, the present invention can make the ink have a natural aroma, so that after the printer is used up, the printed materials will not have an unpleasant smell due to the use of various additives in the ink, and thus can effectively reduce the irritation caused by the unpleasant smell of the ink to the human body. At the same time, by using plant pigments, natural preservatives and binders, compared with chemically synthesized pigments, preservatives and binders, it can further reduce the generation of unpleasant smell of the ink, thereby improving the experience of using the ink and providing more diverse choices for consumers. Detailed implementation mode

[0017] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] An embodiment of the present invention provides an aromatic ink for a printer, which is composed of the following components in proportion: 5-10% of plant pigment, 1-5% of fragrance agent, 2-3% of binder, 0.1-0.5% of anti-gelling agent, 0.2-0.6% of pH regulator, 0.1-0.2% of preservative, 0.2-0.3% of antioxidant, 0.5-0.9% of stabilizer, 1-5% of viscosity regulator, 1-5% of surfactant, 0.1-0.25% of fungicide, and the balance is water solvent.

[0019] The ink produced according to the above components in proportion can be formulated into the required color by adding plant pigment. The fragrance agent adopts a naturally extracted orange flavor agent, which can make the ink have the natural aroma of oranges. Therefore, after using the ink for printing, the ink will not have peculiar smell due to the use of various additives in the ink, and thus can effectively reduce the irritation caused by the ink peculiar smell to the human body, improve the experience of using the ink, and provide more diversified choices for consumers. The use of binder, anti-gelling agent, pH regulator, preservative, antioxidant, stabilizer, viscosity regulator, and surfactant not only ensures the use performance of the ink, but also facilitates the storage of the ink. The fungicide can protect the materials after printing and reduce the occurrence of moth damage.

[0020] Among them, the plant pigment is one of indigo, sappanwood, and Chinese gallnut. When indigo pigment is added, the ink is blue and is used for printing documents or images with a strong professional sense; when sappanwood pigment is added, the ink is red and is used for printing holiday greeting cards and festive posters; when Chinese gallnut pigment is added, the ink is black and is used for printing official documents and reports.

[0021] Indigo, sappanwood, and Chinese gallnut are all natural pigments extracted from plants. Indigo is formed by the condensation of colorless water-soluble 3-hydroxyindole phenol produced by the hydrolysis and fermentation of indigo grass containing free indole phenol and indican after exposure to sunlight and air oxidation; Sappanwood belongs to mordant dyes, and its ochre-brown heartwood contains the original pigment of brazilin. After air oxidation, colored brazilin can be obtained, and under the action of a mordant, various tones such as crimson to purple, orange-red, reddish-brown, brown, light red to dark red can be obtained; Chinese gallnut is rich in tannins. After picking Chinese gallnut, drying, crushing, and soaking in warm water, a khaki dye solution can be obtained. Then, adding alum as a mordant and through chemical action, a black pigment dye solution can be prepared.

[0022] Among them, the binder is one of linseed oil, tung oil, and castor oil. The binder needs to be uniformly mixed with a high molecular resin in a ratio of 3:1 before adding it to the ink.

[0023] The binder can disperse pigment particles in a solvent to form a stable ink system. Linseed oil, tung oil, and castor oil polymerize into a viscous liquid to a certain extent at an appropriate temperature. The ink made with this binder has good gloss, but its oxidation drying speed is slow. Therefore, it needs to be mixed with a polymer resin to improve its application ability.

[0024] Among them, the viscosity regulator is hydroxypropyl methylcellulose, and the anti-gelling agent is one of sodium chloride and ammonium sulfate.

[0025] Hydroxypropyl methylcellulose can form a stable colloidal solution in water. By changing the intermolecular forces in the ink, it can adjust the viscosity of the ink, which is beneficial to ensuring that the ink can flow smoothly during the printing process while maintaining a certain stability. Sodium chloride and ammonium sulfate change the surface charge of pigment particles by adjusting the ionic strength in the ink, thereby preventing their aggregation. At an appropriate concentration, they can be used as effective anti-gelling agents to prevent the ink from hardening and gelling due to the increase in viscosity during storage and restore the usability of the ink.

[0026] Among them, the pH regulator is one of monoethanolamine, diethanolamine, and triethanolamine. After adding the pH regulator to the ink, it is necessary to ensure that the pH value of the ink is neutral.

[0027] Monoethanolamine, diethanolamine, and triethanolamine belong to organic bases. They can balance the acidity and alkalinity of the ink, prevent the ink from deteriorating due to the imbalance of acidity and alkalinity, and also help to improve the stability and printing quality of the ink. In addition, monoethanolamine, diethanolamine, and triethanolamine can also play a certain moisturizing role for the ink. When adding the pH regulator, it is necessary to strictly control the dosage to avoid excessive dosage, which may make the ink tend to be alkaline and have a negative impact on the performance of the ink.

[0028] Among them, the preservative is a natural preservative, which is one or more of camphor leaf extract, tea polyphenols, and perilla extract.

[0029] The preservative has a good inhibitory effect on molds, yeasts, and bacteria. Adding a preservative to the ink can improve the antibacterial performance of the ink and prevent the ink from being contaminated and deteriorated by microorganisms during storage and use. Compared with synthetic preservatives, camphor leaf extract, tea polyphenols, and perilla extract, as natural preservatives extracted from plants, cause less harm to the human body, have higher safety, and are more environmentally friendly.

[0030] Among them, the antioxidant is antioxidant 1010. During storage, it needs to be placed in a dry, cool, and well-ventilated place, avoiding direct sunlight and high temperatures.

[0031] Antioxidant 1010, also known as pentaerythritol ester, has low volatility, good extraction resistance, high thermal stability, long-lasting effect, does not color, does not pollute, is non-toxic, has good compatibility with most polymers, has a good effect on preventing discoloration caused by light and heat. The use of antioxidants can delay the oxidation and polymerization process of vegetable oil, thereby delaying the drying of ink, and then maintaining the stability and durability of the ink, and extending the service life of the ink.

[0032] Among them, the stabilizer is one of gelatin, gum arabic, polyvinyl alcohol, and sodium polyacrylate. Gelatin and gum arabic are natural macromolecular compounds, and polyvinyl alcohol and sodium polyacrylate are synthetic macromolecular compounds.

[0033] As natural macromolecular compounds, gelatin and gum arabic can form complexes with pigment particles in the ink, improving the dispersibility and stability of the pigments. At the same time, they can also increase the viscosity of the ink, improving the adhesion and printing effect of the ink. As synthetic macromolecular compounds, polyvinyl alcohol and sodium polyacrylate can form stable colloidal structures with pigment particles, preventing the aggregation and precipitation of pigment particles. At the same time, they can also adjust the rheological properties of the ink, improving the printing effect and durability of the ink. When used as stabilizers, gelatin, gum arabic, polyvinyl alcohol, and sodium polyacrylate can prevent phenomena such as precipitation and stratification of the ink during storage and use.

[0034] Among them, the surfactant is one of fatty alcohol polyoxyethylene ether and alkylphenol polyoxyethylene ether. Both fatty alcohol polyoxyethylene ether and alkylphenol polyoxyethylene ether belong to non-ionic surfactants.

[0035] In water, fatty alcohol polyoxyethylene ether has a large hydrophilicity due to the formation of hydrogen bonds between the ether bond oxygen atoms in the chain and water molecules, which can reduce the surface tension of the ink and improve its fluidity. Non-ionic surfactants do not ionize in water, have excellent wetting, dispersing, and emulsifying properties, and are insensitive to electrolytes, being suitable for inks with various pH values. In addition, the use of surfactants can also play a role in defoaming and de-bubbling, preventing the generation of bubbles in the ink during storage and application, which may affect the writing or printing effect.

[0036] Among them, after adding the fragrance to the ink, it is necessary to stir back and forth at a rate of 25 to 30 times per minute to make the fragrance and the ink evenly mixed.

[0037] Performing the stirring operation when adding the fragrance can not only ensure the lasting and uniform aroma of the ink, but also avoid the local aggregation of the fragrance in the ink, preventing the situation where the local aroma is too strong or too weak and affecting the printing effect. At the same time, strictly controlling the stirring speed and time during the stirring process can make the fragrance mix more evenly with the ink, and at the same time, it can also avoid causing adverse effects on other components of the ink.
