In recent years, with the continuous improvement of printing technology,
with the promotion of environmental protection policies, uv environmental
protection series inks have been used more and more widely, and are more
and more respected by the printing industry. Today, I will briefly introduce
the main components of environmental protection UV screen ink, and
what are the main components of UV ink? It is mainly composed of polymerized
prepolymer, pigment, active diluent, photoinitiator, filler, additive, etc.
What are the main components of UV ink? Pigment, pigment plays a role in
color development of ink, and it has a direct impact on some characteristics of ink.
Pigments are colored, black or white highly dispersed powders that are insoluble
in water and organic solvents. They can be divided into organic pigments and
inorganic pigments according to their source and chemical composition. Inorganic
pigments are oxides of nonferrous metals, or some metal insoluble metal salts.
Inorganic pigments can also be divided into natural inorganic pigments and artificial
inorganic pigments. Natural inorganic pigments are mineral pigments. Organic
pigments are colored organic compounds, which are also divided into natural and
synthetic categories. At present, synthetic organic pigments are commonly used.
There are many kinds of organic pigments with complete colors, and their
performance is better than that of inorganic pigments.
What are the main components of UV ink? Auxiliaries. The auxiliaries used for
uv ink are mainly used to improve the performance of the ink. The commonly used
auxiliaries mainly include dispersants, defoamers, stabilizers, leveling agents, waxes, etc.
1. Dispersants are mainly used to make the pigment and binder in the ink well wetted,
reducing the ink grinding time; Reduce the oil absorption of the pigment, and prevent
the agglomeration and precipitation of pigment particles in the ink at the same time;
2. Defoamer and leveling agent are mainly used to improve the leveling property of
the ink layer, prevent the generation of shrinkage cavity, make the ink film surface
smooth, and also to improve the luster of the ink layer; 3. Stabilizer is mainly used to
prevent thermal polymerization during ink storage and improve ink storage stability;
4. Waxes are mainly used to change the rheological property of the ink, improve the
water resistance and printing performance, and can also form a smooth wax film on
the dry surface of the ink after curing to improve the wear resistance of the printing
ink layer. At the same time, waxes also play a role in blocking air, reducing oxygen
polymerization inhibition, and are more conducive to surface curing.
