Description
Technical field
The present invention relates to a kind of composition for ink of employing ink-jetting style printing, a kind of specifically uV curable
White ink compositionss, the composition for ink can by way of inkjet printing printing mark symbol on circuit boards.
Background technology
Inkjet printing is a kind of non-contact type mode of printing, without the need for plate-making, word or image can be passed through computer controls
It is directly printed on base material, What You See Is What You Get, is a kind of efficient, high accurately mode of printing.With ink-jet printer and shower nozzle
High speed development, can adopt ink jet printing field expand to the industry using traditional printing mode such as ceramics, textile, and
Printed electronics field is just progressively becoming next ink-jet applications emphasis.Electronic circuit board be on pcb board would generally print character with
Just the mark for checking as subsequent installation or the labelling as maintenance, the character that tradition is printed in the circuit board is to adopt screen printing
The mode of brush, need to first prepare character half tone, then silk-screen is on board substrate, this mode of printing not only high cost, operation it is many,
Cycle is long, and the graph position dimensional discrepancy for being formed is big, and the character for often leading to print occurs that the handwriting is blurred, ghost image etc. lacks
Fall into.And be spray printing on demand using ink-jetting style print character, accurate positioning, a step complete, greatly shorten flow process, reduce
The discharge of energy consumption and waste water, while greatly improving the degree of accuracy of character.
The content of the invention
But, for for the character on printed electronic circuit board, either beaten using screen printing mode or ink-jet
India side formula, requires that formed white characters have the performance of high temperature yellowing-resistant, and this is a big technological difficulties, particularly with spray
Then difficulty is bigger for black printing white ink because ink-jet printing ink require to need to reach in terms of viscosity and surface tension it is special
Requirement could meet spray printing, and this just puts forward higher requirement to the ink-jet ink to develop high temperature yellowing-resistant.
To solve the above problems, a kind of bright white inkjet composition for ink for aiming to provide uV curable of we, institute
State white inkjet composition for ink by way of inkjet printing by character spray printing on electronic circuit board base material, it is described white spray
Black composition for ink Jing spray printings form character and are resistant to 270-290 DEG C of tin bath without xanthochromia, without coming off, and viscosity is in 25- at normal temperatures
35cp.In addition, Jing after inkjet printing, character picture is clear, while the white inkjet composition for ink has excellent covering power
With printing fluency, the needs of PCB large-scale productions can be met.
What the purpose of the present invention was realized particular by following technology path：
A kind of white inkjet composition for ink of uV curable, it include titanium dioxide, pigment dispersing agent, monomer and
Oligomer；The white inkjet composition for ink Jing spray printings formation character is resistant to 270-290 DEG C of tin bath and comes off without xanthochromia, nothing,
Under room temperature, viscosity is in 25-35cp.
Specifically, the monomer is selected from monofunctional monomer, bifunctional monomer and the polyfunctional monomer of UV-curable
Plant or numerous compositions, its consumption accounts for the 60-80% of the white inkjet combination of inks amount of substance.
Preferably, the monomer includes acryloyl morpholine (ACMO), and its consumption accounts for the white inkjet combination of inks material
The 1-20% of amount.Acryloyl morpholine is the thermostability function monomer of excellent performance, can improve the heat stability of system, in molecule
Nitrogen free radical can suppress the polyreaction that oxygen causes, and accelerate the curing rate of system.It has stable tensile property simultaneously, can
To reduce volume contraction during solidification, be conducive to increasing adhesive force.
Preferably, the monomer includes the acrylate of hydroxyl, and its consumption accounts for the white inkjet combination of inks material
The 3-10% of amount.The acrylate of the hydroxyl is selected from 2-(Acryloyloxy)ethanol (HEA), Hydroxypropyl acrylate (HPA), acrylic acid
