Biodegradable green printing ink binder, ink and preparation method of ink

Abstract

The invention relates to a biodegradable green printing ink binder, and belongs to the technical field of ink assistants; the biodegradable green printing ink binder comprises the following componentsby weight: vegetable oil comprising 5-9 parts of soybean oil, 1-3 parts of isooctyl palmitate, 4-8 parts of palm oil, 3-7 parts of linseed oil, and 3-7 parts of tung oil; resin comprising 20 to 28 parts of modified phenolic resin and 10 to 18 parts of dry long-oil alkyd resin; and auxiliary materials comprising 0.5 to 2 parts of aluminum gel and 0.1 to 1 part of an antioxidant; the preparation method of the biodegradable green printing ink binder comprises the following steps: uniformly mixing the vegetable oil and the resin; adding a catalyst into the uniformly mixed vegetable oil, stirring,heating, adding resin, heating to a certain temperature, and keeping the temperature for 1.5-2.5 hours; and finally, adding the auxiliary materials and uniformly stirring. A printing ink comprises the following components in parts by weight: 50-65 parts of the printing ink binder, 8-20 parts of a pigment, 3-10 parts of printing ink oil and 2-4 parts of an auxiliary agent, and a preparation methodof the ink comprises the following steps: mixing the raw materials, and uniformly dispersing. The printing ink has the effects of degradability and excellent performance.

Description

technical field [0001] The invention relates to the technical field of ink additives, in particular to a biodegradable green printing ink binder, ink and a preparation method thereof. Background technique [0002] At present, the main components of ink are pigments, binders and additives. Pigment accounts for about 10%-20% of the ink composition, and the binder accounts for about 70%-80% of the ink. It mainly plays the role of dispersing pigments and additives, and can help the ink form a uniform thin layer after printing. , while protecting the pigment after drying, making it difficult to peel off. Usually, when making pigments, about 10% of other additives are added according to the situation to improve ink performance and adjust ink adaptability. It can be seen that the binder is the main raw material for ink. [0003] Solvent-based ink binders are commonly used in the printing industry. The solvent-based ink binders use petroleum as a solvent. The petroleum solvent co...

Problems solved by technology

[0003] Solvent-based ink binders are commonly used in the printing industry. The solvent-based ink binders use petroleum as a solvent. The petroleum solvent contains a large amount of volatile organic compounds. After volatilization, it not only pollutes the environment, but also affects the safety of relevant operators. It is harmful to health, and petroleum is a non-renewable resource. Extensive use will lead to the depletion of resources. When discarded, it will be landfilled or incinerated. It is difficult to biodegrade and easily produces secondary pollution.
