Description

Technical Field

[0001] The invention relates to the technical field of ink treating agents, and in particular to a waste ink treating agent and a preparation method and application thereof. Background Art

[0002] Ink is one of the indispensable core materials in the modern printing industry. It is mainly composed of pigments, solvents, resins and other auxiliary components. The function of ink is not only to provide color and pattern for paper or other printing carriers, but also to meet different printing needs through adhesion, weather resistance, gloss and other characteristics. In the production process, the use of ink involves multiple links, from mixing, printing to post-processing, and each step may generate waste. With the increasingly stringent environmental regulations, the problem of waste ink and its disposal has gradually become an environmental problem that needs to be solved urgently.

[0003] Waste ink treatment agents are a type of treatment tool specially designed to deal with harmful components, residual solvents and chemicals in waste ink. Its function is to degrade or decompose harmful components in waste ink through physical or chemical means, thereby achieving resource recovery or harmless treatment, reducing environmental pollution and meeting environmental protection standards. In industrial production, waste ink may come from the cleaning process of printing equipment, residual ink from production, and discarded printing products. If not properly handled, these wastes may cause serious pollution to water, soil and air, and thus affect human health and ecological balance. Therefore, it is particularly important to develop efficient and environmentally friendly waste ink treatment agents.

[0004] There are several main reasons for ink treatment. First, as a chemical synthetic product, ink has a complex composition and often contains harmful substances such as solvents, metallic pigments, resins, plasticizers, etc. If these substances are not properly treated and discharged directly into the environment, they may cause long-term and irreversible pollution to water sources, soil and atmosphere. Secondly, with the increasingly stringent environmental regulations, many countries and regions have established strict standards for waste emissions in the printing industry, requiring companies to handle waste ink in compliance with regulations. If relevant regulations are not followed, companies may face huge fines or even suspension of production for rectification. Third, waste ink may also contain precious raw materials, such as some metallic pigments or resins. If they can be recycled and reused, it will help reduce the cost of raw material procurement and reduce resource waste.

[0005] Existing ink treatment agents can be mainly divided into three categories: physical, chemical and biological. Physical waste ink treatment agents usually use physical methods such as dissolution, adsorption or extraction to separate grease, solvents and other harmful substances in the ink from the waste ink. The advantages of this type of treatment agent are simple operation and relatively low cost. However, physical treatment methods often cannot completely degrade the toxic and harmful components in the ink, so its treatment effect is limited, and the effect is even less ideal for high-viscosity or specially formulated inks. Chemical waste ink treatment agents decompose harmful substances in the ink through chemical reactions, such as oxidation, reduction or hydrogenation reactions. This type of treatment agent can generally provide a more thorough treatment effect and can effectively remove solvents, pigments and other harmful components in the ink. However, chemical reactions often require more stringent conditions such as temperature, pressure and reaction time, and new by-products may be produced during the reaction process, which increases the complexity and cost of treatment. Biological waste ink treatment agents use microbial degradation technology and the metabolic activities of microorganisms to decompose harmful components in the ink. This method is environmentally friendly and suitable for large-scale treatment. However, the biodegradation process is slow and has poor adaptability to the complex chemical components in the ink. It may require long-term cultivation of specific microbial flora and has high requirements for environmental conditions such as temperature and humidity.

[0006] However, existing waste ink treatment agents still have certain limitations and problems. First, many traditional ink treatment methods have certain environmental pollution risks. For example, some chemical treatment methods may produce harmful byproducts during the reaction process, and even cause secondary pollution. Although the existing physical treatment agents are simple to operate, they can only remove the solvents or relatively simple chemical components in the ink, and cannot completely remove the pigments and other heavy metal substances in the ink. This requires enterprises to add multiple treatment steps in the ink recovery process, which increases costs and operational complexity. Secondly, most of the current waste ink treatment agents are less effective in treating specific types of inks. Different types of inks, such as water-based inks, solvent-based inks, UV inks, etc., have large differences in composition and properties, which leads to the lack of "versatility" of existing treatment technologies, poor treatment effects of certain inks or overly complicated treatment processes. Furthermore, some current waste ink treatment methods still rely on relatively expensive raw materials and equipment, which makes the cost of ink treatment high and cannot be popularized and applied in large-scale production. In addition, the efficiency of many treatment technologies is also limited, the treatment process is slow, and they are not suitable for large-scale, high-efficiency treatment needs.

[0007] Based on this, it is urgent to develop an efficient, economical and harmless treatment agent to treat waste ink. Summary of the invention

[0008] The purpose of the present invention is to develop an efficient, economical and harmless waste ink treatment agent.

[0009] The first aspect of the present invention is:

[0010] A waste ink treatment agent is provided.

[0011] The second aspect of the present invention is:

[0012] Provided is a method for preparing a waste ink treating agent.

[0013] The third aspect of the present invention is:

[0014] Application of the waste ink treating agent.

[0015] Specifically, the technical solution adopted according to the first aspect of the present invention is:

[0016] A waste ink treatment agent, comprising the following components:

[0017] Butyl methacrylate;

[0018] Ricinoleic acid polyester;

[0019] Tea saponin;

[0020] Lauryl Betaine;

[0021] Sodium salt;

[0022] Ether compounds;

[0023] Alcohol compounds;

[0024] Alkyl polyglycosides;

[0025] Filling particles;

[0026] water.

[0027] According to the embodiments of the present invention, one of the technical solutions has at least one of the following advantages or beneficial effects:

[0028] The waste ink treatment agent of the present invention can efficiently treat ink residues, thanks to the synergistic effect of multiple components. Each component not only plays a role in dissolution, emulsification, penetration, etc. in chemistry, but also accelerates the removal of ink through physical means (such as the friction-assisted effect of filler particles). Its excellent ink treatment efficiency is achieved through a multi-level mechanism of action, especially through the coordination of surfactants, solvents and lubricants, to achieve an efficient, environmentally friendly and sustainable cleaning effect.

[0029] In the waste ink treatment agent of the present invention, butyl methacrylate can dissolve organic components in the ink, especially resins, pigments and dyes in the ink. It interacts with the components in the ink through its lipophilic properties, helps the ink to disperse, dissolve or emulsify, so that the ink residue can be effectively removed from the surface or converted into a treatable form. Its low polarity structure helps to break the molecular chain of the ink, making the ink residue looser and easier to remove.

[0030] The ricinoleic acid polyester in the waste ink treatment agent of the present invention is a lubricant and thickener, which can improve the fluidity and adhesion of the treatment agent and enhance its permeability to ink residues. Since the ricinoleic acid polyester itself is a polyester made by reacting natural vegetable oil (castor oil) and polyols, it has excellent biodegradability and good affinity for ink components. Therefore, it not only helps dissolve the ink, but also further reduces the adhesion between the ink and the substrate through lubrication, helping the ink to fall off more easily.

[0031] Tea saponin in the waste ink treatment agent of the present invention reduces the interfacial tension between the oily components in the ink and the water-soluble substances through its amphiphilic molecular structure, thereby enhancing the dispersibility and solubility of the ink. Tea saponin can form a stable emulsified system between water and ink, promoting the decomposition and removal of the ink. Its natural source and biocompatibility make it have great application prospects in environmentally friendly ink treatment agents.

[0032] Lauryl betaine in the waste ink treatment agent of the present invention not only helps to reduce the surface tension between the ink and the treatment agent, but also enhances the emulsification of the ink. Lauryl betaine has strong hydrophilicity and lipophilicity, so it can effectively combine the oily part and the aqueous part of the ink to form a stable emulsion. This process allows the residual oily part of the ink to be wrapped by water and promotes its removal from the surface, ultimately improving the ink treatment efficiency.

[0033] The sodium salt in the waste ink treatment agent of the present invention can help the ink treatment agent maintain a stable aqueous solution state to avoid stratification or precipitation during use. At the same time, its ionic properties may also enhance the dispersion effect on ink particles, making the ink residue easier to dissolve or emulsify.

[0034] The ether compound in the waste ink treating agent of the present invention destroys the molecular structure of the ink, making the components in the ink (such as pigments and resins) more easily dissolved or loosened, thereby achieving efficient removal.

[0035] The alcohol compound in the waste ink treating agent of the present invention can interact with the organic components in the ink, thereby promoting the components such as the resin or dye in the ink to be dissolved more effectively.

[0036] The alkyl polyglycoside is used in the waste ink treatment agent of the present invention to reduce the surface tension between the ink and the substrate. It can effectively separate the ink from the surface and improve the removal efficiency of the ink residue. The advantage of the alkyl polyglycoside is that it is biodegradable, which not only does not burden the environment during the ink cleaning process, but also helps other surfactants to play a better role.

[0037] The filler particles in the waste ink treating agent of the present invention can enhance the mechanical cleaning performance of the treating agent. By providing a certain physical friction force, the filler particles can help the ink residue to be easily wiped off or peeled off during the cleaning process.

[0038] According to one embodiment of the present invention, the waste ink treatment agent comprises the following components in parts by weight:

[0049] According to one embodiment of the present invention, the waste ink treatment agent comprises the following components in parts by weight: butyl methacrylate, 1-2 parts;

[0050] Ricinoleic acid polyester, 2-3 parts;

[0051] Tea saponin, 0.5-1.5 parts;

[0055] Alcohol compounds, 5-10 parts;

[0056] Alkyl polyglycoside, 0.1-0.5 parts;

[0057] Filling particles, 4-6 parts;

[0058] Water, 80-100 parts.

[0059] According to one embodiment of the present invention, the waste ink treatment agent comprises the following components in parts by weight: butyl methacrylate, 1-2 parts;

[0060] Ricinoleic acid polyester, 2-3 parts;

[0061] Tea saponin, 0.5-1.5 parts;

[0064] Ether compound, 5-8 parts;

[0065] Alcohol compounds, 5-10 parts;

[0066] Alkyl polyglycoside, 0.1-0.5 parts;

[0067] Filling particles, 4-6 parts;

[0068] Water, 80-100 parts.

[0069] According to one embodiment of the present invention, the waste ink treatment agent comprises the following components in parts by weight: butyl methacrylate, 1-2 parts;

[0070] Ricinoleic acid polyester, 2-3 parts;

[0071] Tea saponin, 0.5-1.5 parts;

[0074] Ether compound, 5-8 parts;

[0075] Alcohol compounds, 5-9 parts;

[0076] Alkyl polyglycoside, 0.1-0.5 parts;

[0077] Filling particles, 4-5 parts;

[0078] Water, 80-100 parts.

[0079] According to one embodiment of the present invention, the waste ink treatment agent comprises the following components in parts by weight:

[0080] Butyl methacrylate, 1-2 parts;

[0081] Ricinoleic acid polyester, 2-3 parts;

[0082] Tea saponin, 1-1.5 parts;

[0083] Lauryl betaine, 1-2 parts;

[0084] Sodium salt, 1-3 parts;

[0086] Alcohol compounds, 5-9 parts;

[0087] Alkyl polyglycoside, 0.1-0.5 parts;

[0088] Filling particles, 4-5 parts;

[0089] Water, 80-100 parts.

[0090] According to one embodiment of the present invention, the sodium salt includes at least one of sodium carbonate, sodium bicarbonate, sodium persulfate and sodium chloride. Selecting different types of sodium salts can adjust the properties of the cleaning agent according to the composition and processing requirements of the ink, thereby enhancing its effect in the ink removal process. Sodium chloride can promote the emulsification of surfactants by increasing the ionic strength of the solution; sodium persulfate, as a strong oxidant, can play an oxidizing role in ink treatment and help decompose some difficult-to-remove ink components, especially resins and dyes with a high degree of polymerization; sodium bicarbonate has mild alkalinity and can adjust the pH value of the treatment agent to a moderate range to avoid excessive alkalinity from corroding the substrate or equipment. It can also help loosen and decompose certain ink components by slightly increasing the pH value, thereby improving the solubility and emulsification ability of the ink, thereby improving the cleaning efficiency.

[0091] According to one embodiment of the present invention, the ether compound includes at least one of ethylene glycol tert-butyl ether, ethylene glycol dimethyl ether and diethyl ether. When the ether compound is used in combination with different types of sodium salts, their respective characteristics can be brought into play, the effect of the waste ink treatment agent can be optimized, and the efficiency of ink removal can be improved.

[0092] When ether compounds are combined with sodium bicarbonate, they can not only promote the dissolution of certain insoluble components in the ink, but also help the ether solvent to work more effectively through moderate alkalinity adjustment.

[0093] Ether solvents can help dissolve organic substances in inks, and the oxidation of sodium persulfate can destroy the structure of ink molecules, making them easier to remove. Especially for inks containing complex polymers, the combination of sodium persulfate and ether compounds can greatly improve the treatment effect and help quickly decompose and remove stubborn ink residues.

[0094] Ether solvents can interact with the components in the ink to form an emulsion, while sodium chloride helps the ink to be removed more easily by adjusting the electrolyte concentration of the solution and improving the emulsification efficiency. In addition, sodium chloride helps to enhance the stability of the solution and avoid solvent stratification problems caused by too low electrolytes.

[0095] According to one embodiment of the present invention, the alcohol compound includes at least one of pentaerythritol, ethylene glycol and ethanol.

[0096] According to one embodiment of the present invention, the filler particles include at least one of graphite, acetylene black and titanium dioxide. Pentaerythritol, as a polyol, contains multiple hydroxyl groups in its molecular structure, which can interact with ether solvents and sodium salts to increase the polarity of the solution, thereby helping to dissolve polar components in the ink.

[0097] The low volatility and high boiling point of ethylene glycol make it less likely to evaporate during the treatment process, providing a longer working time and helping to improve dissolution efficiency. At the same time, ethylene glycol can reduce the surface tension of the solution, allowing the ink to mix better with the solvent and improve dispersibility, especially when dealing with inks containing more pigments or other solid components.

[0098] In practical applications, ink residues can be removed more quickly when using ethanol. In addition, ethanol has a better cleaning effect and can remove grease and adhesive substances in some inks.

[0099] According to one embodiment of the present invention, the components of the waste ink treatment agent further include an auxiliary agent, and the auxiliary agent includes at least one of a solubilizer, a corrosion inhibitor and a defoaming agent.

[0100] Specifically, the technical solution adopted according to the second aspect of the present invention is:

[0101] A method for preparing the waste ink treating agent comprises the following steps:

[0102] Under heating conditions, butyl methacrylate, ricinoleic acid polyester, tea saponin, lauryl betaine, sodium salt, ether compounds, alcohol compounds, alkyl polysaccharide and filling particles are mixed in water to obtain the waste ink treating agent.

[0103] According to the embodiments of the present invention, one of the technical solutions has at least one of the following advantages or beneficial effects:

[0104] The method of the present invention prepares a waste ink treatment agent in water by heating and mixing a plurality of chemical components, which significantly improves the ink removal efficiency and can more effectively remove ink residues. The treatment agent has good stability during use and can be evenly distributed to avoid redeposition of ink, while improving the solubility and dispersibility of ink to ensure a smooth cleaning process. In addition, the method of the present invention also has antibacterial properties, which helps prevent the growth of microorganisms and prolong the shelf life of the treatment agent. By increasing the volatility of the solvent, the treatment agent can accelerate the dissolution of ink residues, thereby improving work efficiency. Finally, the added physical medium can assist in cleaning and removing ink residues, further optimizing the treatment effect.

[0105] According to one embodiment of the present invention, the heating condition is to mix butyl methacrylate, ricinoleic acid polyester, tea saponin, lauryl betaine, sodium salt, ether compound, alcohol compound, alkyl polysaccharide and filler particles in water at 60-65° C., and after 30-60 minutes, heat it to 90-95° C. The heating step of the whole process helps to improve the solubility and emulsification ability of the treatment agent, so as to better exert its cleaning effect.

[0106] Another aspect of the present invention also relates to the use of the waste ink treatment agent in the treatment of packaging printing ink, including the waste ink treatment agent as described in the first embodiment.
