Environment-friendly vegetable oil type ink and preparation process thereof

Abstract

The invention discloses an environment-friendly vegetable oil type ink and a preparation process thereof. The environment-friendly vegetable oil type ink mainly comprises the following raw materials by weight: 20-35 parts of a coloring agent, 3-5 parts of auxiliary agents, 30-48 parts of rosin-modified phenolic resin and 20-30 parts of a solvent, wherein the auxiliary agents are mainly composed of1-5 parts of an anti-friction agent, 0.5-2 parts of a drying agent, 0.5-3 parts of an anti-drying agent and 3.5-4.5 parts of other auxiliary agents, and the solvent is mainly composed of soybean oil,linseed oil and tung oil. According to the ink in the invention, resin with low solubility and medium and low viscosity is selected and used, and vegetable oil esters having performance similar to the performance of mineral oil are elected and used, so the ink of the invention overcomes the problem of slow fixation speed, poor printability, too hard ink properties, great colloidality and too large yield value of conventional ink, has rich color and good effect, and accords with the development trend and the green development concept advocated at present.

Description

technical field

[0001] The invention belongs to the technical field of ink, and in particular relates to an environment-friendly vegetable oil ink and a preparation process thereof. Background technique

[0002] VOC, that is, volatile organic compounds, is mainly emitted from automobile exhaust, paint, resin, adhesive, printing, pharmaceuticals, dry cleaning industry, petroleum industry and other various factories or ordinary households. The VOC in the ink mainly refers to the mineral oil component in the ink. During the drying process of the ink, the resin and vegetable oil components can be oxidized in the air to form a film and stay on the surface of the substrate, while the mineral oil component will be overheated. Through volatilization, it is finally discharged into the environment to form VOC. These organic volatiles can form a more serious greenhouse effect than carbon dioxide, and will form oxides and photochemical smog under sunlight, seriously polluting the atmos...
