Problems solved by technology

[0004] Although soybean ink has become the mainstream of offset printing inks in the world, the research and development of soybean ink is very difficult
At present, the production technology of soybean ink is relatively mature in developed countries such as the United States, Japan, and Germany, and its application fields are quite extensive. However, the domestic progress is quite slow, and there are few studies on the production process of soybean ink, and all soybean ink used needs to be imported.
[0005] At present, domestic research hotspots are mainly focused on polymerized soybean oil, but the performance of polymerized soybean oil prepared by existing methods is poor, especially the viscosity is low, and the adhesion is poor, so it is basically not practical

Abstract

The invention discloses a preparation method of epoxy polymerized soybean oil for ink. The preparation method comprises the following steps of: firstly preparing thermally polymerized soybean oil by carrying out thermal polymerization on soybean oil under the condition of certain thermal polymerization reaction process parameters; then carrying out epoxidation on the thermally polymerized soybean oil by utilizing a high-efficiency catalyst to prepare the epoxy polymerized soybean oil. The epoxy polymerized soybean oil disclosed by the invention has the advantages of high viscosity, low acid number and good adhesive property, and meets the requirement of a soybean ink connecting material. Soybean ink prepared by taking the epoxy polymerized soybean oil as the soybean ink connecting material is high in volatilizing speed and high in adhesive force on various offset litho printing substrates and can substitute a large quantity of soybean oil ink products on the market.

Description

[technical field] [0001] The invention relates to a preparation method of epoxy-polymerized soybean oil for printing ink. [Background technique] [0002] Traditional printing inks are generally composed of binders, pigments and fillers, mineral oils, additives and other components, of which petroleum-based mineral oils (such as benzene, toluene, xylene, etc.) are used in an amount of 20-60%. A large amount of toxic and harmful VOC (Volatile Organic Chemical) will be produced in the process of manufacturing and ink printing, which will bring serious hidden dangers to the health of production operators and the natural ecological environment. According to statistics, the annual VOC emissions caused by various inks in the world have reached hundreds of thousands of tons, which can not only lead to a more serious greenhouse effect than carbon dioxide, but also form harmful oxides and photochemical smog under the action of sunlight, thus Seriously pollute the air environment. Es...
