Problems solved by technology

However, due to certain differences in the chemical properties of the vegetable oil and petroleum fractions, it cannot fully meet the printing requirements. At present, it can only replace a part of the petroleum fractions in the ink, that is, the volatile components in the ink only reach 30%. about

Embodiment

[0021] Embodiment: the preparation of offset printing yellow ink of the present invention

[0022] Preparation:

[0023] Resin (phenolic resin modified by rosin) 28Kg

[0024] Dry vegetable oil (linseed oil) 14Kg

[0025] Semi-dry vegetable oil (modified soybean oil) 28Kg

[0026] Pigment (Organic Pigment Yellow No. 12) 18Kg

[0027] Desiccant (prepared from metal and organic acid) 1.5Kg

[0028] White beeswax 3Kg

[0029] Auxiliary 7.5Kg

[0030] Preparation Process:

[0031] The preparation process of the ink can be divided into three stages: preparation of liquid binder, stirring pre-dispersion and grinding fine dispersion.

[0032] An example of the preparation of this ink is as follows:

[0033] In the mixing pot, add linseed oil, modified soybean oil, and rosin-modified phenolic resin products in sequence according to the above-mentioned feeding ratio, and stir for several hours at a high temperature of 200-300 degrees to form a liquid binder. Then add the liqui...

Abstract

The invention relates to a flexographic ink with a high degradation rate, which is characterized by comprising the following compositions by weight: 15 to 20 weight portions of coloring agent, 24 to 29 weight portions of resin, 12 to 15 weight portions of dry plant oil, 24 to 29 weight portions of semidry plant oil, 1 to 2 weight portions of drying agent, 2 to 4 weight portions of animal and vegetable wax and 5 to 10 weight portions of auxiliary agent. The ink has greatly improved natural component content, and the degradable components reaching more than 60 percent, and reduces the pollution of the ink to the environment.

Description

technical field [0001] The invention relates to an offset printing ink with high degradation rate. Background technique [0002] In recent years, with the rapid development of the economy and the prosperity of the market, ink printing is involved in almost all walks of life. From the packaging materials of various large and small products to food bags, food containers, toilet paper towels, napkins and other items that are in direct contact with the human body that are closely related to daily life, almost all of them are printed with information such as patterns, advertisements or texts. The annual ink consumption The volume showed a rapid upward trend. Inks used for printing contain components such as colorants, binders and additives, most of which are non-degradable organic components. The binder is obtained by mixing resin, vegetable oil, mineral oil (feeding ratio: 40%, 20%, 40%) at a high temperature of 200-300 degrees for several hours. It accounts for 50-70% of the ...
