Description

Technical Field

[0001] The invention belongs to the technical field of inks, and in particular relates to a soybean oil-based environment-friendly offset rotary ink and a preparation method thereof. Background Art

[0002] Environmentally friendly offset rotary inks are mainly used to print newspapers, books, magazines, teaching materials and other reading products that are in close contact with readers. Their toxicity directly affects the safety of readers and the reading environment. With the requirements of environmental protection, the printing industry has higher and higher requirements for inks, and green and pollution-free has become the development trend of the industry.

[0003] Traditional offset rotary inks are still produced using asphalt and petroleum resin binders, and mineral oil is used as a solvent. The aromatic hydrocarbon solvents in petroleum solvents will evaporate as the ink dries, thereby polluting the air. The polycyclic aromatic hydrocarbons and their derivatives contained in petroleum solvents will remain in the printed matter and will also be harmful to human health. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a soybean oil-based environment-friendly offset rotary ink and a preparation method thereof.

[0006] Preferably, the raw materials for preparing the soybean oil modified phenolic resin connecting material include 120-160 parts of epoxidized soybean oil, 150-230 parts of alkylphenol, 1-2 parts of liquid rosin, 80-100 parts of formaldehyde, 10-15 parts of triethylamine, and 250-300 parts of ethanol; the various components are mixed evenly and added into a reactor, reacted at 160-180°C for 4-6 hours, to obtain the soybean oil modified phenolic resin connecting material.

[0007] Preferably, soybean oil is placed in a reaction kettle, nitrogen is introduced as a protective gas, the mixture is stirred and heated to 300-350° C., 4% by mass of magnesium oxide is added, and the reaction is carried out for 2 hours to prepare soybean polymerized oil.

[0008] Preferably, the filler is barium sulfate or calcium carbonate.

[0009] Preferably, the additive comprises a mixture of one or more of an antioxidant, an anti-emulsifier and a desiccant.

[0010] Preferably, the desiccant is at least one of cobalt isooctanoate, manganese isooctanoate, and zirconium isooctanoate;

[0011] The demulsifier is a block copolymer of ethylene oxide and propylene oxide.

[0012] The method for preparing soybean oil-based environment-friendly offset rotary ink comprises the following steps: mixing soybean oil-modified phenolic resin connecting material, soybean oil synthetic polymer oil, soybean oil and additives, stirring evenly, adding fillers and pigments, continuing to stir evenly and grinding, and obtaining the soybean oil-based environment-friendly offset rotary ink.

[0013] Application of soybean oil-based environmentally friendly offset rotary ink in book or newspaper printing varieties.

[0014] The advantages and positive effects of the present invention are:

[0015] The main components of the binder and solvent are both soybean oil-based. The principle of similarity is used to homogenize the ink and improve the uniformity of the prepared ink. The ink has good wettability and adhesion, can adapt to high-speed printing, and is stable during the printing process.

[0016] Soybean oil as a solvent can effectively reduce volatile organic solvents, effectively improve the printing environment, and is beneficial to the health of printing workers; soybean oil ink printing can reduce the residual petroleum components, reduce the irritating odor of printed products, and reduce the harm to the user's body;

[0017] In addition, when the printed materials are recycled, they are easy to deink and the paper fibers are less damaged, so that recycled paper with better brightness and higher quality can be obtained, which has good degradability. DETAILED DESCRIPTION

[0018] The following is a description of embodiments of the present invention.

[0019] The invention relates to a soybean oil-based environment-friendly offset rotary ink and a preparation method thereof. A soybean oil-based ink is provided, wherein the binder adopts phenolic resin modified by epoxy soybean oil as the binder, and soybean polymer oil is further added. The main components of the environment-friendly offset rotary ink include soybean oil or are modified by soybean oil. The ink can be mixed more quickly and uniformly through the principle of like-for-like compatibility, and has better stability.

[0020] The soybean oil-based environment-friendly offset rotary ink comprises 60-70 parts of a soybean oil-modified phenolic resin binder, 5-10 parts of a soybean oil synthetic polymer oil, 5-10 parts of soybean oil, 10-15 parts of a filler, 20-25 parts of a pigment, and 3-5 parts of an additive. When preparing the soybean oil-based environment-friendly offset rotary ink, firstly, the soybean oil-modified phenolic resin binder, the soybean oil synthetic polymer oil, the soybean oil and the additive are mixed, and stirred for 1-2 hours until the mixture is uniform; then, the filler and the pigment are added to the aforementioned mixture, and the mixture is stirred for 0.5-2 hours until the mixture is uniform and ground to obtain the soybean oil-based environment-friendly offset rotary ink.

[0021] The raw materials for preparing the soybean oil modified phenolic resin connecting material include 120-160 parts of epoxy soybean oil, 150-230 parts of alkylphenol, 1-2 parts of liquid rosin, 80-100 parts of formaldehyde, 10-15 parts of triethylamine, and 250-300 parts of ethanol; during the preparation, the various components are mixed evenly and added to the reactor, and reacted at 160-180°C for 4-6 hours to obtain the soybean oil modified phenolic resin connecting material. The preparation method of soybean oil polymer oil is as follows: soybean oil is placed in a reactor, nitrogen is introduced as a protective gas, stirred and heated to 300-350°C, 4% mass fraction of magnesium oxide is added, and after reacting for 2 hours, soybean polymer oil is prepared. The filler is barium sulfate and / or calcium carbonate.

[0022] The newly developed environmentally friendly rotary offset ink uses a new soybean oil-modified phenolic resin binder, completely eliminates asphalt and petroleum resin components in the formula, and uses soybean oil, a renewable resource, instead of mineral oil, a non-renewable resource, as a solvent. It is a new generation of green printing ink.

[0023] The additives include a mixture of one or more of an antioxidant, an anti-emulsifier and a desiccant, wherein the antioxidant is antioxidant 1010; the desiccant is at least one of cobalt isooctanoate, manganese isooctanoate and zirconium isooctanoate; and the anti-emulsifier is an ethylene oxide propylene oxide block copolymer.

[0024] The prepared soybean oil-based environmentally friendly offset rotary ink can be used for printing books or newspapers, which can not only achieve rapid inking, but also reduce the harm caused by the ink components to manufacturers and users. The ink has good wettability and adhesion, can adapt to high-speed printing, and is stable during the printing process. It is not easy to produce flying ink, ink splashing and other phenomena, thereby improving the printing efficiency and quality. Soybean oil as a solvent can effectively reduce volatile organic solvents, effectively improve the printing environment, and is beneficial to the health of printing workers; soybean oil ink prints can reduce the residual petroleum components, reduce the irritating odor of printed products, and reduce the harm to the user's body. When the printed products are recycled, they have good de-inking properties and less damage to the paper fibers, so that recycled paper with good brightness and high quality can be obtained, and the degradability is good.
