Description
Technical field
The invention belongs to offset ink technical fields, and in particular, to a kind of wear-resisting offset ink and its production technology.
Background technique
Offset ink needs to add to assign the performance that the ink after printing has abrasion-resistant when making offset ink
A certain amount of wax ingredient.In the prior art, the production technology of offset ink is first by wax powder and varnish, vegetable oil and mineral oil
It is stirred, is then ground to be prepared into wax liquor or slack wax, be then again directly appended to obtained wax liquor or slack wax
Simply be dispersed with stirring to prepare offset ink in base ink.This wax liquor or slack wax are first prepared however, in the prior art
It is then added to the production technology that offset ink is prepared in base ink, since wax liquor is pulpous state, and slack wax is paste, and since wax exists
Degree of scatter in ink determines the wear-resisting property of ink, however, the wax liquor of pulpous state and slack wax paste are dispersed in Ji Mo respectively
In total specific surface area it is smaller, i.e., wax liquor or slack wax base ink in degree of scatter it is relatively low, to cause obtained glue
The wear-resisting property of printing ink is poor.In addition, during wax liquor or slack wax are added to the dispersion of base ink by the prior art, due to not having
Have consideration dispersion condition, thus but also the degree of scatter of wax is not high, cause the wear-resisting property of the offset ink obtained by it compared with
Difference.

Nitration mixture made of ratio with 1:1.
7. a kind of wear-resisting offset ink according to claim 1, which is characterized in that the modified Nano SiO2By such as lower section
Method preparation:
(1) 24g Nano-meter SiO_2 is taken2Powder is put into the three-necked flask equipped with 80mL acetone, ultrasonic disperse 90-100min, then
15mL methyltriethoxysilane is added dropwise into flask, then 68mL distilled water is added dropwise, in 66 DEG C of isothermal reaction 7h, after the reaction was completed
It then is dried in vacuo 5-6h at 45 DEG C up to neutrality with dehydrated alcohol repeated filtration washing immediately, just modified SiO is made2Powder
End;
(2) 12g just modified SiO is taken2In 100mL isopropanol, 18mL silane coupling agent KH570 is added in ultrasonic disperse 60min, in
7h is reacted at 75 DEG C, after reaction immediately with dehydrated alcohol repeated filtration washing until neutrality, is dried in vacuo 5- at 45 DEG C
Modified Nano SiO is made in 6h2Powder.
8. a kind of production technology of wear-resisting offset ink, which comprises the steps of:
Step S1, under room temperature, slowly epoxy acrylic resin is added in isopropanol while stirring, after adding, continues to stir
30-40min adds vegetable oil and vegetable fatty acid esters, stirs 50-60min, is uniformly dispersed, and binder is made;
Step S2, by the binder of 60%-70%, pigment, modified clay, modified Nano SiO2It is placed in high speed disperser,
Disperse 1h under the conditions of 3000r/min, mixture is made;
Step S3, then mixture is ground using three-roll grinder, before grinding, zirconium oxide bead is added as grinding medium
Matter, is ground to fineness≤15 μm, and temperature of charge must not exceed 50 DEG C when grinding;
Step S4, remaining binder, dispersing agent, defoaming agent and levelling agent are added, 1-2h is stirred under the conditions of 500r/min, is made
Obtain wear-resisting offset ink.
