Problems solved by technology

Solvent-free resin-based plugging inks have become popular in developed countries such as the United States and Japan. However, many domestic resin-based plugging ink products are still in the research and development stage, and the existing domestic resin-based plugging ink products generally have low performance. The problems are mainly reflected in: 1. The viscosity of the ink is high, which is not conducive to screen printing plugging; 2. The degree of curing is large, the solidification of the cured product is poor, and there are more bubbles and cavities; 3. The storage period and shelf life are short.

Embodiment 1-21

[0036] Prepare the nano-calcium carbonate composite resin-based plugging ink as follows, and make it through the following steps:

[0037] (1) Weigh each substance according to the amount of each component in Table 1, and mix them together to obtain a mixed material.

[0038] (2) Put the mixed material in the disperser and stir for 1-5 hours. During the stirring process, feed circulating cooling water at 25°C into the circulating cooling pipe of the dispersing machine, and control the temperature of the mixed material during the stirring process through the circulating cooling water. , Keep the temperature of the mixed material below 40°C.

[0039] (3) Transfer the mixed material to a three-roll mill, and grind it three times under the cooling of circulating cooling water at 25°C until the viscosity of the mixed material is 40-60 Pa·s / 25°C.

[0040] (4) Transfer the mixed material to a linear mixer, and stir under vacuum for 1-5 hours under the cooling of circulating cooling ...

Abstract

The invention relates to the technical field of taphole resin, and particularly relates to nanometer calcium carbonate composite resin-based taphole printing ink and a preparation method thereof. The nanometer calcium carbonate composite resin-based taphole printing ink is prepared by uniformly mixing epoxy, a glycidol type active diluting agent, a latent curing agent, an imidazole type curing accelerant and inorganic powder. By using the epoxy of which the viscosity is 4-6Pa*s / 25 DEG C, the viscosity of the nanometer calcium carbonate composite resin-based taphole printing ink disclosed by the invention can be reduced, the crosslinking density of the nanometer calcium carbonate composite resin-based taphole printing ink can also be increased, the hardness of a cured substance and the glass transition temperature of the nanometer calcium carbonate composite resin-based taphole printing ink are increased. By adding the inorganic powder, agglomeration of nanometer calcium carbonate powder is prevented, the dispersion effect of mixed materials is enhanced, the rheological property of the nanometer calcium carbonate composite resin-based taphole printing ink can also be improved, the thixotropy of the nanometer calcium carbonate composite resin-based taphole printing ink is improved, and the expansion coefficient of the nanometer calcium carbonate composite resin-based taphole printing ink is effectively reduced; besides, the heat conductivity of the nanometer calcium carbonate composite resin-based taphole printing ink can also be improved, so that difference of curing degree of the printing ink in holes can be reduced and problems of internal cavity or incomplete curing are prevented.

Description

technical field [0001] The invention relates to the technical field of plugging resins, in particular to a nano-calcium carbonate composite resin-based plugging ink and a preparation method thereof. Background technique [0002] In the early 1990s, Japan and the United States pioneered the application of high-density interconnection technology (High Density Interconnect Technology, HDI), which introduced blind buried holes in conventional PCBs, fine line width and line spacing, so that it can Manufacture thin, multi-layer, stable, high-density interconnection, high-definition, high-reliability and low-cost PCBs that cannot be realized by conventional multi-layer board technology, adapting to the trend of lighter, smaller, thinner and more reliable electronic products It meets the requirements of the development in the direction of higher reliability and meets the needs of the new generation of electronic packaging technology to continuously improve the packaging density. ...
