Description

Technical Field

[0001] The present invention relates to an environmentally friendly ink diluent composition and a preparation method thereof, in particular to an environmentally friendly ink diluent composition and a preparation method thereof, which utilizes natural products such as tuna oil and ethanol fraction secreted by bedbugs to replace harmful substances such as acetone and toluene in traditional diluents, while reducing the use of ethanol and improving the coloring and quick-drying properties of ink. Background Art

[0002] Ink refers to various liquid or solid substances used for writing, painting and printing, including pigments and pigments, and is used in various fields where fonts or paintings are used.

[0003] Generally speaking, there are printing inks for multiple publications, inks for recording or writing in one's own handwriting, and inks for drawing.

[0004] However, these inks have the characteristic that dyes easily clump, and commercially available inks tend to add additives such as diluents to prevent dye aggregation, control ink viscosity, and produce effects such as quick drying and improved texture.

[0005] However, since commercially available diluents mainly use harmful components such as acetone or toluene, research has recently been conducted to develop ink diluents that replace these harmful substances or ink compositions containing them.

[0006] In this regard, Korean Patent Publication No. 10-2011-0115635 discloses a method for manufacturing ink that has the functions of absorbing and deodorizing electromagnetic waves, emitting anionic components, and eliminating harmful substances.

[0007] However, there is currently a lack of research on diluent compositions that can be used in ink compositions, and further research is needed.

[0032] For the sake of convenience of explanation, the size and thickness of each configuration shown in the drawings are shown, and the present invention is not necessarily limited to the size and thickness of the shown structures.

[0033] The features of each of the various embodiments of the present invention may be combined with each other in part or in whole, and as can be fully understood by those skilled in the art, they may be technically interlocked and driven, and each embodiment may be performed independently of each other or together in an associated relationship.

[0034] One aspect of our clinic is the extraction stage of tuna oil, which is to extract the oil in a supercritical manner by drying tuna at low temperature; the fractionation of bedbug secretions with ethanol to obtain a bedbug secretion ethanol fraction; the primary mixing stage, which is to prepare a primary mixture by mixing tuna oil, bedbug secretion ethanol fraction, shellac, fig fiber and dimethyl sulfoxide (DMSO); and the secondary mixing stage, which is to mix the primary mixture, cypress oil and ethanol to prepare a secondary mixture; it provides a method for preparing an environmentally friendly ink diluent composition.

[0035] Next, you can use Figure 1 The preparation method of the environmentally friendly ink diluent composition according to one embodiment of the present invention is described below.

[0036] First, the oil is supercritically extracted by drying the tuna at low temperatures.

[0037] Grateloupia filicina is a species of seaweed in the genus Rhodophyta that grows in rock pools in intertidal zones. It is commonly eaten as a seasoning or pickled food. The tuna oil in the present invention can be used as a substitute for acetone and toluene in ink thinner compositions. Specifically, tuna oil in the present invention can be mixed with an ethanol fraction secreted by stink bugs to provide an acetone and toluene replacement.

[0038] If an extraction method other than supercritical is used, the composition of the oil may vary, which may reduce the effectiveness of the diluent produced by that method.

[0039] In one embodiment, the tuna oil extraction process may further include a purification step to obtain a supernatant after centrifugation at a temperature of 2 to 5° C. for 10 to 30 minutes.

[0040] The purification process of the present invention is to remove impurities by centrifuging tuna oil at low temperature to precipitate impurities and obtain only supernatant, so as to make the mixture with the ethanol fraction secreted by the stinking ash smooth, thereby improving the ink solubility of the ink diluent prepared thereby.

[0041] Next, the bed bug secretions are fractionated with ethanol to obtain a bed bug secretion ethanol fraction.

[0042] The above-mentioned bed bug secretions are secretions secreted by bed bugs (Pentatomidae) of the family Cimex. Bed bug secretions are characterized by a foul odor and are used by bed bugs to protect their bodies from predators.

[0043] The bed bug secretion ethanol fraction of the present invention can be used as a substitute for acetone and toluene by fractionating the stink bug secretion into ethanol to remove unnecessary components and purify the components, which is then mixed with tuna oil.

[0044] Next, a primary mixture was prepared by mixing tuna oil, stink bug secretion ethanol fraction, shellac, fig fiber, and dimethyl sulfoxide (DMSO).

[0045] Shellac is a solvent made by extracting the secretions of the Laccifer lacca. When scale insects colonize tree trunks in the forest to reproduce, they suck the sap, secreting resin that accumulates thickly like bark. When scraped off with a knife, it peels off like cork bark. The shellac is ground, sieved to remove foreign matter, cleaned, refined, dried, heated, melted, and placed through a strainer. Squeezed out like a rag, the dark brown shellac, melted by the heat, flows out like glue. After refining, it is cooled, drawn, and stretched into a thin layer, like a sheet of paper. It is then hung outside to dry like clothing before being cut into small pieces for sale.

[0046] Shellac of the present invention may be included in the thinner composition to improve thinner application and adhesion.

[0047] Fig fiber refers to fiber extracted from figs, the fruit of the fig tree (Ficus carica), a deciduous shrub in the dicotyledonous Urticaceae family.

[0048] Fig fiber of the present invention may be included in thinner compositions to provide the thinner fibers with quick drying properties and improved adhesion.

[0049] Dimethyl sulfoxide (DMSO) is a colorless, odorless, hygroscopic liquid that is a powerful solvent that can dissolve many aromatic and unsaturated hydrocarbons, organic compounds, and many other substances because it is a highly polar organic liquid.

[0050] Specifically, the content of each material used to prepare the primary mixture can be 15-20% by weight of tuna oil, 8-10% by weight of bedbug secretion ethanol fraction, 15-20% by weight of shellac, 2-5% by weight of fig fiber and 45-60% by weight of DMSO.

[0051] In one embodiment, the primary mixing step may be performed at a pressure of 1800 to 2200 mmHg and a temperature of 140 to 160° C. If the pressure exceeds the above conditions, the ink solvent, application, and adhesion of the diluent composition prepared thereby may be reduced. If the temperature exceeds the above conditions, the primary mixture may not be mixed smoothly.

[0052] Finally, asphalt and ethanol are mixed into a primary mixture to prepare a secondary mixture, thereby completing the environmentally friendly ink diluent composition.

[0053] Cypress oil refers to oil extracted from the cypress tree (Chamaecyparis obtusa), an evergreen shrub belonging to the genus Cupressus. Cypress oil contains a large amount of natural antibacterial substances called phytoncides, which have excellent antibacterial effects. Due to its strong, unique aroma, it is also used as an ingredient in air fresheners.

[0054] Specifically, the content of each material used to prepare the secondary mixture may be 70-80% by weight of the primary mixture, 10-15% by weight of asphalt, and 10-15% by weight of ethanol.

[0055] In one embodiment, the secondary mixing step may further include a stirring step by generating ultrasonic waves for 20 to 60 minutes during the secondary mixing.

[0056] In the present invention, the process of stirring by generating ultrasonic waves can improve the stability of the ink diluent composition, thereby stabilizing the molecular structure of the secondary mixture and making the mixing smoother.

[0057] Another aspect of the clinic is to provide an environmentally friendly ink diluent composition prepared by the above manufacturing method.

[0058] Below, we will explain the composition of the present invention and its effect in more detail through specific embodiment and comparative example.However, this embodiment is intended to describe the present invention in more detail, and the scope of the present invention is not limited to these embodiments.

[0059] [Example 1]

[0060] First, the tuna is dried at low temperature and then the oil is extracted using supercritical fluid to obtain tuna nuari oil.

[0061] Next, bed bug secretions were collected from the bed bug glands and then used with ethanol powder to prepare a bed bug secretion ethanol fraction.

[0062] Then, 18 wt% of tuna oil, 8 wt% of bed bug secretion ethanol fraction, 16% of shellac, 5% of fig fiber and 53% of DMSO were mixed at a pressure of 2000 mmHg and a temperature of 155°C to prepare a primary mixture.

[0063] Finally, 75 wt% of the primary mixture, 15 wt% of asphalt, and 10 wt% of ethanol were mixed to prepare a secondary mixture, thereby completing the environmentally friendly ink thinner composition. The completed environmentally friendly ink thinner composition was named Example 1.

[0064] [Example 2]

[0065] The preparation method of Example 1 was the same, but after the tuna oil was extracted during the tuna oil extraction process, the tuna oil was centrifuged at 4° C. for 20 minutes, and then a purification step was additionally included to obtain only the supernatant. The true ink diluent composition was named Example 2.

[0066] [Example 3]

[0067] The preparation method of Example 1 is the same, but in the secondary mixing process, an environmentally friendly ink diluent composition is prepared by further comprising the steps of generating ultrasonic waves for 20 to 60 minutes and stirring for secondary mixing, and is named Example 3.
