Soybean oil oligomer and preparation method thereof

Abstract

The invention relates to a soybean oil oligomer and a preparation method thereof. The soybean oil oligomer is prepared from the following raw materials in percentage by weight: 90.9 percent of waste food processing oil, 4.1 percent of water, 1.4 percent of hydrogen peroxide solution and 3.6 percent of activated carclazyte. The preparation method comprises the following steps of: filtering, floating, and heating to 50 DEG C in a reaction kettle for reaction; then, spraying with an aqueous hydrogen peroxide solution, carrying out a thermal reaction, standing still, delaminating, discharging impurity wastewater at the bottom and increasing the temperature to 120-130 DEG C; adding the activated carclazyte, keeping the temperature, stirring, sampling and comparing colors until the temperature is not reduced any more; and stopping temperature retaining and filtering to obtain the soybean oil oligomer when the temperature is reduced to a temperature below 70 DEG C. The invention adopting the advanced hydration-oxidation method and the activated carclazyte absorption method has simple and convenient process operation and obvious floating and decoloring effects. The refined soybean oil oligomer obtained by using the method has high purity and is particularly suitable for producing the link stuff of various kinds of news ink.

Description

[0001] This application is the application number 200510098306.6, the application date is September 07, 2005, and the name of the invention is "Recycling Food Processing Waste Soybean Oil to Manufacture Environment-friendly Offset Rotary News Ink", a divisional application of one application. technical field [0002] The invention relates to a soybean oil oligomer suitable for use in soybean oleoresin binders in the field of IPC classification C09D and C09F, in particular to a soybean oil oligomer prepared from recycled food processing waste soybean oil and its preparation method. Background technique [0003] Food processing industries such as instant noodles, fried foods, fast food restaurants, large restaurants, etc., use a large amount of edible vegetable oil, especially soybean oil, every day. These oils have been used under high temperature for a long time, and a large amount of unsaturated fatty acid esters have polymerized into low-molecular compounds, the color beco...

Problems solved by technology

[0005] In order to solve the purification and purification of recycled food processing waste soybean oil, and introduce the obtained soybean oil oligomers into offset printing press ink, so that the ink has both environmental protection characteristics and excellent printability and high quality of printed products, this paper The invention proposes a new waste soybean oil purification and purification technology, and uses the obtained soybean oil oligomer as the main raw material to prepare ink binder, which replaces most or all toxic and harmful petroleum solvents, and further solves the problem that soybean oil is not easy to dry , to achieve the intended purpose
