Embodiment 1
[0050] Table 2 prepares the raw materials and proportioning of black UV photocurable inkjet ink
[0051]
[0052] According to the formula and dosage of Table 2, prepare UV curable inkjet ink:
[0053] (1) Preparation of color paste: Weigh 10g carbon black, 10g polyurethane acrylate and mix and grind 20 times with SM65 three-roll mill to obtain pigment resin dispersion system; 20g pigment resin dispersion, 80g mixed monomer (EOEOEA:TPGDA : TMPTA=11:1:5), 1g of dispersing and leveling agent was stirred at room temperature for 2 hours with a T80basic type homogenizer at a speed of 3000r / min, and then filtered through a 0.45 micron membrane to obtain a carbon black slurry.
[0054] (2) Preparation of film-forming phase:
[0055] First dissolve 10.2g of mixed photoinitiator (819:907=5.5:4.7) and 2.3g of active amine co-initiator with 12g of monomer, then add 13.2g of polyester acrylate, 8.8g of polyurethane acrylate, and 20g of carbon black The slurry, 1g of dispersing and le...
Embodiment 2
[0073] Present embodiment is on the basis of embodiment 1, changes the kind of pigment, and selects suitable photoinitiator for use, other remains unchanged.
[0074]
[0075] It can be seen from the above table that in order to obtain good conductivity after electroless plating, carbon black is preferred.
Embodiment 3
[0077] This embodiment is on the basis of embodiment 1, changes the consumption of carbon black, other remains unchanged.
[0078]
[0079] Note: The peeling of the copper layer causes the line to be disconnected, so the resistance is infinite.
[0080] It can be seen from the above table that in order to obtain good conductivity after electroless plating, the preferred proportion of black color paste is 3%-7%.

Abstract
The invention discloses a preparation method of an ultraviolet-curing activator based on an ink-jet printing technology and a process for carrying out activation treatment by using the activator. The preparation method comprises the following steps: firstly, preparing a film-forming phase from prepolymer resin, a nano pigment colorant, a photoinitiator and additives and the like; then, preparing an activation phase from nano metal particles and a hydrogen-preventing agent and the like; finally, uniformly mixing the film-forming phase, the activation phase and a hydrogen-preventing agent so as to obtain the activator capable of carrying out ink-jet printing. The process for carrying out activation treatment comprises the following steps: printing the activator on a matrix by ink-jet printing, carrying out ultraviolet-curing on the matrix subjected to ink-jet printing, and placing into a chemical plating solution to metalize, thereby achieving the purpose of directly selective metallization of the insulating matrix. The activator disclosed by the invention is not settled, and can be preserved for a long time; the activator is low in viscosity, and does not block ink-jet holes; the consumption of precious metals is less, and the cost is low; an obtained copper conducting circuit is continuous, dense, and high in electrical conductivity; in the preparation and application processes of the activator, the harm to the human body and environment is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of electroless plating activation technology, and more specifically relates to a method for preparing an activator based on inkjet printing technology and a process for using the activator to perform activation treatment. Background technique [0002] Printed Electronics (Printed Electronics) uses the additive method to make electronic devices and circuits, which is more environmentally friendly and efficient than the traditional photolithography subtractive method. Among them, inkjet printing technology based on UV-curable activator has obvious advantages in the preparation of flexible printed circuit boards (Flexible Printed Circuit, FPC), which makes the production of circuit boards as easy as printing documents in the office, and the wiring is dense, which can Make production flexible and electronic products miniaturized. The basic process of inkjet printing circuit is: print the designed CAD wiring dia...
