Description

Technical Field

[0001] This invention belongs to the field of emulsified oil technology, specifically relating to a bio-based emulsified oil, its preparation method, and its application. Background Technology

[0002] Emulsified oil, simply put, is a stable, non-stratified oil droplet formed by uniformly mixing oil, water, and additives. In the water-based ink industry, it is an auxiliary agent used in the grinding of water-based pigments, acting as a dispersant and defoamer, and can replace mineral oil. Mineral oil refers to oil-based products produced from raw materials extracted from petroleum hydrocarbons and used in the manufacture of inks. It mainly includes saturated hydrocarbon mineral oils (MOSH) composed of straight-chain, branched, and cyclic compounds with 16-35 carbon atoms, and aromatic hydrocarbon mineral oils (MOAH) composed of polyaromatic compounds with 1-7 or 3-7 carbon atoms. Based on relevant mineral oil assessment reports published by the European Food Safety Authority in 2012 and 2019, MOAH (especially 3-7 ring MOAH) has potential carcinogenicity and mutagenicity, i.e., potential carcinogens; MOSH can accumulate in human tissues, and long-term, high-dose intake is harmful to the liver. A French decree of April 13, 2022, explicitly prohibited the use of mineral oil in packaging and printed materials distributed to the public. Therefore, higher technical requirements and material analysis capabilities are needed to produce water-based pigments and inks. To improve water-based inks, it is essential to develop water-based pigments effectively. Currently available emulsified oils for water-based pigments suffer from drawbacks such as easy separation, mineral oil content, and foaming. This necessitates repeated stirring of the emulsified oil during water-based pigment production. Furthermore, when stored in tanks, separation can lead to residue at the bottom after extraction. Additionally, defoamers must be added to the formulation, and its use in products with mineral oil restrictions must be avoided. This not only results in poor quality water-based pigments but also increases the variety of products and imposes a greater workload on production line workers.

[0003] CN111763574A discloses a sodium fatty acid methyl ester sulfonate composition particle for detergent production. This invention solves the problem of hydrolysis of sodium fatty acid methyl ester sulfonate in high-temperature, strongly alkaline systems, as well as the problems of poor stability, high irritation, easy decomposition, and easy agglomeration of sodium fatty acid methyl ester sulfonate during use, and the problem of slow dissolution rate of sodium fatty acid methyl ester sulfonate at low temperatures. The use of sodium fatty acid methyl ester sulfonate in combination with sodium oleate can achieve complementary performance. CN116444915A discloses a long-lasting antibacterial polyvinyl chloride film composition and its preparation method. This invention mentions that epoxidized soybean oil prepared from soybean oil is used as a dispersant in the formulation system of the composition, giving the material good dispersibility; it also serves as a natural ingredient, making the product green, healthy, and environmentally friendly. However, problems such as demulsification, stratification, foul odor, and excessive foaming of emulsified oils stored in tanks still exist.

[0004] Therefore, developing an environmentally friendly, safe emulsified oil that does not separate into layers is an urgent problem to be solved in this field. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a bio-based emulsified oil, its preparation method, and its application. The bio-based emulsified oil effectively solves the problems of instability caused by easy separation of water-based pigments during storage and the need for pump clogging during pigment grinding, ensuring the environmental friendliness and safety of the finished ink.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a bio-based emulsified oil, wherein the components of the bio-based emulsified oil, by weight, include: 2-10 parts of vegetable oil, 5-15 parts of sodium fatty acid methyl ester sulfonate, 5-15 parts of sodium oleate and 5-20 parts of nonionic surfactant.

[0008] In this invention, sodium methyl ester sulfonate (MES) and sodium oleate are combined to achieve complementary properties. The hard water resistance of sodium methyl ester sulfonate improves the poor calcium soap resistance of sodium oleate. Simultaneously, the low-temperature resistance of sodium oleate improves the low-temperature cold resistance of MES. MES can produce foam in deionized water; adding sodium oleate can quickly defoam at low concentrations. The ratio of MES to sodium oleate can be adjusted according to the desired foaming requirements to obtain the desired performance.

[0009] The vegetable oil is in the range of 2-10 parts by weight, for example, 2 parts, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, and specific values ​​between the above values. Due to space limitations and for the sake of brevity, this invention will not exhaustively list the specific values ​​included in the range.

[0010] The sodium methyl ester sulfonate of fatty acids is 5-15 parts by weight, for example, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 12 parts, 14 parts, 15 parts, and specific values ​​between the above-mentioned values. Due to space limitations and for the sake of brevity, the present invention will not exhaustively list the specific values ​​included in the range.

[0011] The sodium oleate is in the range of 5-15 parts by weight, for example, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 12 parts, 14 parts, 15 parts, and specific values ​​between the above values. Due to space limitations and for the sake of brevity, this invention will not exhaustively list the specific values ​​included in the range.

[0012] Sodium oleate is Raynol PN-1440, an anionic surfactant from Qingdao Ruinuo Chemical Co., Ltd., with a solid content of ≥40%. Sodium oleate and MES have a very good effect on carbon black soiled cloths. The low-temperature resistance of sodium oleate improves the low-temperature cold resistance of MES.

[0013] The nonionic surfactant is present in parts by weight of 5-20 parts, for example, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 12 parts, 14 parts, 15 parts, 18 parts, 20 parts, and specific values ​​between the above values. Due to space limitations and for the sake of brevity, the present invention will not exhaustively list the specific values ​​included in the range.

[0014] Preferably, the vegetable oil includes soybean oil, which serves as a lubricant and can improve the color development and gloss of the black paste.

[0015] Preferably, the pH value of the sodium fatty acid methyl ester sulfonate is 4.5-8.0, for example, it can be 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, and specific values ​​between the above values.

Thirdly, it can be compounded with polyols, oleic acid, and other raw materials to solve the problem of low-temperature stability.

[0018] Preferably, the nonionic surfactant includes any one or a combination of at least two of GT99, alkylolamide, or isopropanolamide.

After the oil component is pumped out, water cannot dissolve and carry away the remaining oil component on the pipeline. GT99, as a nonionic surfactant, can dissolve the oil component and carry it to the reaction vessel. It is also miscible with water. Therefore, the order of adding materials is from oil component to GT99 and finally water. This avoids oil component contamination on the pipeline from being carried to other products and affecting their quality. The GT99 is NOVELUTION GT99 nonionic surfactant from Sasol (China) Chemical Co., Ltd., with an active ingredient content of 90±1% and a pH value (1% active ingredient aqueous solution): 5.0-7.5. It has a narrow gel range, is easily dispersed and dissolved in water, and can be used for wetting and dispersing various inorganic and organic pigments and fillers, improving the wetting efficiency of pigment and filler surfaces. It is APEO-free, has low VOC content, and extremely low odor. It has excellent synergistic effects when combined with other surfactants.
