Plant soybean oil replaces the highly polluted chemical crude oil and is naturally pure. Because soybean oil is an edible oil, it can be completely integrated into the natural environment after decomposition. In various formulations of vegetable oil inks, soybean oil ink is a truly applicable environmentally friendly ink, and its output is abundant, and its performance is safe and reliable. The printing effect is good and meets the standards of the printing ink, and the environmental protection is excellent. Compared with traditional inks, it has bright color, high concentration, good gloss, good water adaptability and stability, abrasion resistance, and resistance to drying.
1. Environmental protection
Soybean ink has no VOC volatile substances. VOC is a volatile organic compound contained in petroleum and contains aromatic polycyclic hydrocarbons. It is one of the most intense carcinogens. It is used in ink manufacturing, printing, drying process or in equipment cleaning and waste. When the ink is processed, a large amount of organic components volatilize, which not only seriously harms the health of production operators, but also causes great damage to the environment. At present, the volatilization of VOCs in printing inks has become one of the important pollution sources of environmental pollution. When manufacturing inks, printing and drying, or cleaning manufacturing equipment and printing facilities, if soybean ink is used, VOC emissions will be reduced, which is beneficial to the environment and health.
2 friction heat
The readers of newspapers are often stained with ink when reading. This is because the ink on the substrate after printing using traditional inks is easily rubbed off. Soybean inks are more resistant to rubbing than traditional inks, leaving newspaper readers unaffected by hand blacking. At the same time, there is no unpleasant irritating odor. Soybean ink has a much higher boiling point than petroleum volatiles. When the oil is heated by a laser printer or photocopier, it will not evaporate and stick to paper, nor will it contaminate machine parts.
3. Easy to remove ink from waste paper
For deinking of recovered waste paper, soy ink is easier to deink than ordinary ink, and paper fiber damage is less. More than 80% of paper used in newspapers is made of recycled paper. This feature of soy ink makes waste paper less wasteful when recycled and recycled, and has lower recovery costs and is highly competitive in the industry. After the deinking treatment, the waste soybean ink residue is also relatively easy to degrade, which is beneficial to the sewage treatment and the quality of discharged water. This characteristic of soy ink is a very favorable factor for waste paper recycling or recycled paper.
4. Good color
The raw material of soybean ink is salad oil and other edible oils. It was jointly developed by Japan Elite Tang Printing Co., Ltd. and Toyo Ink Co., Ltd. As a refined vegetable oil, salad oil is excellent in fluidity and coloring after being processed through a series of rigorous decolorization, deodorization, and removal of free fatty acids. And high transparency, colorful, not easy to fade, suitable for a wide range of color printing. The UV mixed soy ink for waterless printing is excellent in deinking performance and easy to recycle; it can print high-quality printed matter without powder spraying, and can obtain excellent prints in post-processing such as film lamination, printing and coating, etc. Improve the operating environment.
5. Good ink resistance
Compared with cured inks or waterless offset inks, soy oil inks dry more slowly. However, from the perspective of practical results, the transferability of the ink is good, and the ink repellency in the field is good, and the highlights of the dots are evenly distributed. After ordinary offset ink reaches the paper, the solvent penetrates quickly. In the part near the paper surface, the ink film will break off, while the soybean oil ink will penetrate slowly, and the peeling surface of the ink is closer to the side of the blanket. The thicker ink film is transferred to the paper surface, so the ink transfer amount increases.
6. Good laser resistance
Soybean ink is the best choice when prints need laser resistance. Its boiling point is much higher than that of petroleum. When the ink is heated by a laser printer or photocopier, it will not volatilize and stick to paper, nor will it contaminate the parts of the printer.
7. Renewable
Unlike vegetable oils, petroleum inks are non-renewable resources. Soybean oil, for example, is a rich resource for sustainable regeneration and biodegradability. It can continuously provide raw materials for ink production, and has a good environmental protection. The use of vegetable fats (such as soybean oil) as a substitute for some petroleum-based mineral oils to make inks can promote the industrial use of vegetable oils in various countries, expand the application range of vegetable oils, and at the same time reduce the consumption and import of non-renewable oil and save foreign exchange.
8. Low overall printing costs
It was found that vegetable inks are easier to deink than traditional inks, and that paper fibers have less damage and good quality recycled paper. The use of this characteristic of vegetable inks results in less wasted waste and less recycling costs in waste paper recycling. Waste ink residue after deinking treatment is more likely to be degraded, which facilitates wastewater treatment and controls the quality of discharged water. Soybean inks have a wide range of colors, rich colors and bright colors. A small amount of ink can exhibit the effects that a large number of traditional inks can exhibit. In addition, because traditional inks contain organic compounds and substances, in order to avoid causing environmental pollution, its disposal has become a problem that plagues ink manufacturers and printers. However, soy ink can be backfilled and mixed in new inks, which is not only conducive to environmental protection, but also reduces production costs.
9. Good for energy security
The oil that traditional inks rely on is a non-renewable resource. With the extensive use of oil, it has become increasingly exhausted. The energy crisis has become the biggest problem faced by mankind. Many industries have turned their attention to renewable plant resources, such as biodiesel. The soybean oil in vegetable inks is derived from natural, can be infinitely regenerated, and can be biodegraded. It has the unparalleled advantages of traditional inks both in terms of resource utilization and environmental protection.
