Abstract

The invention discloses an ink composition and a preparation method thereof. The ink composition is prepared from the following components in parts by weight: 15-25 parts of a metallic pigment, 3.5-5 parts of tween, 3-5 parts of diglycidyl phthalate, 2.5-3 parts of polyepoxysuccinic acid, 2-4 parts of white carbon black, 2-3 parts of azodiisobutyronitrile, 2-3 parts of urea, and 20-30 parts of diethylene glycol diethyl ether. The invention also provides a preparation method of the ink composition. The preparation method comprises the following steps: (1) weighting 15-25 parts of the metallic pigment, 3.5-5 parts of tween, 3-5 parts of diglycidyl phthalate, 2.5-3 parts of polyepoxysuccinic acid, 2-4 parts of white carbon black, 2-3 parts of azodiisobutyronitrile and 2-3 parts of urea; (2) adding the weighted components into a three-roll grinder to grind for 10-20 minutes at a temperature of 110-125 DEG C, and carrying out heat preservation for 2-3 hours at a temperature of 155-160 DEG C; and (3) adding 20-30 parts of diethylene glycol diethyl ether into a product obtained in the step (2), and carrying out uniform ultrasonic mixing, so that the ink composition is obtained.

Description

technical field [0001] The invention relates to the field of ink materials, in particular to an ink composition and a preparation method thereof. Background technique [0002] With the continuous advancement of electronic technology, electronic components are becoming increasingly refined, and both the manufacturing process and the selection of materials need to be more refined. In the printing process of circuit boards, the choice of ink is a very important key factor. Conductive inks are needed in circuit boards, but conductive inks are often difficult to control because of their viscosity, and it is difficult to meet the needs of circuit board pattern printing. A patterned conductive layer that provides a stable electrical connection. [0003] Most of the current conductive inks are composed of phenolic resins, and their conductive inks have a short storage time at room temperature and require a long drying and curing time. And the manufacturing process has higher requi...
