Problems solved by technology

Many students are used to reading while eating, touching the textbooks with their hands and then touching the food. In this way, a large amount of non-environmentally friendly substances used in the printing process of textbooks will enter the human body along with the food, causing certain poisons to the body. For the health of children, the research direction of my institute is to make vegetable oil-based textbook inks replace traditional offset printing inks

Abstract

The invention discloses safe and environment-friendly vegetable oil-based book and periodical ink and a preparation method thereof, and relates to the technical field of printing ink. The method comprises the steps: preparing modified soybean oil from soybean oil and tung oil under the catalysis of zinc oxide and anthraquinone; then, coating the surface of the nano spherical ferric oxide with hexadecyl trimethyl ammonium bromide; putting into an ethyl orthosilicate ethanol solution; obtaining a pretreated additive after stirring reaction, carrying out acid etching on the pretreated additive toobtain an additive blank, mixing the additive blank with ethyl acetate, carrying out freeze drying to obtain an additive; finally mixing the modified soybean oil with rosin modified phenolic resin, adding the additive, the organic pigment, paraffin and the assistant, and stirring and mixing to obtain the safe and environment-friendly plant-based book and periodical ink. The safe and environment-friendly plant-based book and periodical ink prepared by the method has a relatively high drying rate and relatively low VOC content.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to a safe and environment-friendly vegetable oil-based ink for books and periodicals and a preparation method thereof. Background technique [0002] The environment has always been an issue that has attracted much attention in the world. Under the current situation of rising calls for "green environmental protection", the domestic printing and packaging industry has continuously improved its requirements for environmental protection. As an industry that will have a certain impact on the environment, it has also begun to pay attention to its own behavior and participate in environmental protection actions. Ink is one of the raw materials of printed products, and it has also started its own green road, and various types of environmentally friendly inks have emerged as the times require. The use of environmentally friendly inks has gradually become a fashion in the printing indu...
