Abstract

The invention discloses soybean oil-based environment-friendly offset rotary news ink and a preparation process thereof. The ink comprises the following raw materials in parts by weight: 15.6-17.2 parts of an organic pigment, 28.8-33.5 parts of high-viscosity soybean oil-based resin oil, 35.5-41.8 parts of low-viscosity soybean oil-based resin oil, 3.5-8.2 parts of stuffing and 3.5-5.5 parts of anauxiliary, wherein the high-viscosity soybean oil-based resin oil comprises the following raw materials: 40-40.5 parts of high-viscosity rosin modified phenolic resin and 59-60 parts of soybean oil;and the low-viscosity soybean oil-based resin oil comprises the following raw materials: 33-37 parts of low-viscosity rosin modified phenolic resin and 65-68 parts of soybean oil. The ink disclosed bythe invention is low in cost, good in oil solubility, economic and practical, and is capable of reducing the waste discharge of various processes, decreasing the volatile organic compound componentsof printing ink, reducing the pollution to the atmospheric environment, reducing the cost of ink formula.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to a soybean oil-based environment-friendly offset rotary news ink and a preparation process thereof. Background technique [0002] For existing printing inks, it is not only necessary to pursue high efficiency and high selectivity, but also to pursue the "greening" of the product in the reaction process. This "green and environmentally friendly product" should promote the high reaction rate of chemical products. ; Fewer by-products, low energy consumption, lower raw materials, but also require reaction conditions, reaction medium and the generated products are low or non-toxic, so it is of great significance to solve environmental pollution. [0003] However, the mineral oil system offset rotary press inks currently on the market not only contain a high proportion of mineral oil, resulting in higher VOC emissions, but also cause serious pollution to the environment, atmospher...
