Industry knowledge: of the four components of ink

Ink By the pigments, binders, fillers, additional material and other components.

(1) pigment Pigment in the ink color plays a role in some of the characteristics of the ink it has a direct impact.

Pigment is insoluble in water and organic solvents, color, black and white high-dispersion Powder , According to the source and chemical composition, divided into Organic Pigments And Inorganic Pigments Two categories.

  inorganic pigment is Non-ferrous metals Oxide, or some insoluble metal salts, Inorganic Pigments Inorganic pigments are divided into natural and artificial inorganic pigments, inorganic pigments are natural mineral pigments.

organic pigment is a colored organic compounds, also divided into two major categories of natural and synthetic. Now commonly used in synthetic organic pigments, organic pigments varieties, Color More complete, better than inorganic pigments.

Dyes are organic compounds, which can be dissolved in water, sometimes dissolved in organic solvents, in a certain dyes can be prepared in an insoluble color precipitate, called color lakes, pigments, for the manufacture of printing ink.

Printing ink pigments used in high demands, especially in color, dispersion, Light offerings, transparency, color pigment colors close to the required spectral color, saturation should be as large as possible, the three primary colors used in magenta ink , blue, yellow pigment transparency must be high, all the paint not only waterproof, but also to connect quickly and evenly and material combination, pigment oil absorption capacity should not be too large, the best color with alkali, acid, alcohol-resistant potential resistance properties.

(2) binders Binders is a major component of printing ink, pigment dispersion play to give the appropriate Ink Stick, mobility and transfer performance, and after printing through the film to the surface of pigment fixation on the role of print. Connection material commonly known as transfer ink oil.

Connection material can be made of various materials, such as all kinds of dry vegetable oils, most of the connection can be used to make ink materials, mineral oil may also be made of binders, solvents and water, and a variety of Synthetic resin Made of materials can be used to connect.

Ink rheology, viscosity, neutral, acid value, color, water resistance and printing properties, etc. depending on connection material, the same paint, using different binders, different types of ink can be made; and a connection with the material, use a different color. Still made of the same type of ink, because it can not change the fundamental properties of ink, so The quality of ink, except with the paint, the main depends on the connection material.

(3) packing Filler is white, transparent, translucent or not out of the powdery substance. Mainly from the filling, filling paint section, the appropriate use of these fillers, the reduction in pigment consumption, lower costs, but also regulate the nature of ink, such as thinning thick, mobility, etc., also increased formulation flexibility.

(4) Additional material Additional material is in the ink manufacturing, as well as use in printing, to improve the performance of the ink itself, some additional material. Ink prepared in accordance with the basic composition, in some features still can not meet the requirements, or because of changes in conditions, but can not meet the requirements of the printing use when adding a small amount of supporting material must be resolved.

Additional material has many, such as: desiccant, anti-desiccant, diluent, withdraw viscosity, plasticizers and so on.
