Performance test
1st, viscosity test
Since ink is in printing process, viscosity is excessive, i.e., can cause poor fluidity, dry slow, dirty version, paste more than 25 pools
Phenomena such as version；Viscosity is low, and the good fluidity of ink, fast drying, layer of ink are thin, few with ink amount, but viscosity is too low, i.e., less than 5 pool meetings
There is the shallow situation of color.
Test method：It is 25 DEG C ± 1 DEG C in temperature to ink made of embodiment 1-3, comparative example 1-5, relative humidity
Under conditions of 65% soil 5%, each group ink sample is stirred evenly respectively, then respectively at measuring viscosity, every group of weight in viscosimeter
It is 3 times multiple.
Test result：Viscosimeter measures the viscosity of ink, and then viscosity is high greatly for numerical value, conversely, the small then viscosity of numerical value is low, it will be viscous

2nd, anti-after tack test
Ink printed product needs storehouse storage to handle, therefore when the anti-after tack of product is bad, finished product can be caused to after-tack
Phenomenon.
Test method：The ink that embodiment 1-3, comparative example 1-5 are provided with 300 mesh screen paintings on PVC claddings, and
In 60 DEG C of oven dryings 5 minutes.Then again by the printing sample after the completion of drying, storehouse is one in a manner that printing surface is to printing surface
It rises or non-printed side is stacked together with printing surface.The cladding being stacked together is clipped in 5cm × 5cm glass plates, above
With the iron block weight of 3KG weight, then it is placed in 50 DEG C of baking ovens 9 hours.After test, base material is taken out, inspects adhesion situation.
It can normally tear and indicate, without sticking together, can not normally tear expression and stick together exception.It tests 30 times, is calculated not per set product
Yield, measurement result are as shown in table 2 below.(fraction defective=stick together abnormal number/30*100%)

3rd, adhesive force is tested
The adhesive force for printing ink is the important indicator for judging its quality.
Test method：Embodiment 1-3, comparative example the 1-5 ink provided are printed in PVC material, it is small that printing sample places 2
When more than, until print coated surface drying until.It is closely attached on printing coated surface with 3M adhesive tapes.Push down printing material on the other hand
Matter, the other hand rapidly come test tape tearing (moment tears).Tape pull printed article direction, can divide three directions into
Row is tested, and on printed article, hand-held adhesive tape one end is torn, torn to the right and torn upwards to the left.It inspects and tears
On the adhesive tape opened, printing coated surface sticks together situation.Printing film severe detachment be then determined as it is unqualified, printing film without or
It slightly comes off, is determined as qualification.It is tested 30 times per set product, calculates fraction defective, measurement result is as shown in table 3 below.(fraction defective
=unqualified number/30*100%)
The adhesive force fraction defective statistical result of 3 each group ink of table
| Fraction defective % | |
