Definitions
- the present invention relates to a conductive paint having good adhesion to a metal oxide molded article. Background technology
- Metal oxide molded articles such as IT0 (Indium Tin Oxide) or 10 (Indium Oxide) are widely used as transparent conductive films for electrodes such as liquid crystal displays and solar cells.
- IT0 Indium Tin Oxide
- 10 Indium Oxide
- silver paste is used as an electrode for soldering in order to extract a lead wire from a metal oxide compact.
- an object of the present invention is to provide a conductive paint satisfying the following requirements (1) to (3).
- the present invention relates to a phenolic resin (solid content) that satisfies the following conditions with respect to 100 parts by weight of silver mesh netting powder having a silver plating amount of 30 parts by weight. 6.0 parts by weight, a saturated fatty acid or unsaturated fatty acid or a metal salt thereof or a capping agent containing a saturated fatty acid or unsaturated fatty acid 0.2 to 0.7 parts by weight, triethanol
- the conductive paint was composed of 1.0 to 4.0 parts by weight of ruamine and 0.1 to 1.0 parts by weight of dihydroxybenzene.
- a resole-type phenolic resin that satisfies the following relationship:
- the conductive paint is prepared by adding an appropriate amount of an antifoaming agent and an appropriate amount of butyl carbitol / acetylacetyl (9.5 to 0.5 to 8.0 / 2.0 weight ratio) as a solvent and kneading. It can be configured.
- the conductive paint according to the present invention configured as described above has the following requirements: (1) good adhesion to a metal oxide molded body such as ITO, 10; (2) solderability; Refurbishment Adds that the solderability of the one-way type is good, and adds the above items (2) and (3) under various curing conditions.
- the reason why the silver plating amount of the silver plating copper powder is set to 30% by weight or less is that if the silver plating amount is increased by 30% by weight, a migration problem occurs and soldering is performed. At this time, the silver diffuses into the solder quickly, causing a problem that the paste is cleaved with the solder.
- the amount of the above-mentioned phenolic resin as a binder of silver-medium copper powder exceeds the above upper limit, the solderability will not be favorable. The binding of the net powder deteriorates and the adhesion decreases. In addition, in the case of silver plated copper powder / binder, the adhesion to the ITO once improves as the amount of binder is reduced, but this is due to the increase in the amount of silver plated copper powder and the heat in the heat curing process. This is probably because the history is eased.
- Japanese Patent Application Laid-Open No. 2-161172 For the relationship between the above transmittances (a) to (2) of the phenolic resin, see Japanese Patent Application Laid-Open No. 2-161172.
- a saturated fatty acid or unsaturated fatty acid or a metal salt thereof or a coupling agent containing a saturated fatty acid or unsaturated fatty acid is a saturated fatty acid having 1 carbon atom.
- Unsaturated fatty acids such as palmitic acid, stearic acid, and arachinic acid having b to 20 are zomalic acid, oleic acid, and linolenic acid having 16 to 18 carbon atoms.
- these metal salts they are salts with metals such as sodium, potassium, copper, aluminum and zinc.
- Examples of potting agents containing saturated or unsaturated fatty acids include isoprovir tristearoyl titanate, isopropirt trioctanoyl titanate, isopropirdimethytacryl and sostearoyl titanate. You. These dispersants are added to improve the dispersion of the silver plating copper powder, but if the amount exceeds the upper limit, the adhesion to ITO and I0 decreases, and the lower limit is broken. In this case, the dispersion of the copper powder becomes poor, and the solderability decreases.
- Triethanolamine is added to improve the adhesion to copper and I0.In consideration of solderability, 2.5 parts by weight is an appropriate amount. Solderability deteriorates, and if it falls below the lower limit, adhesion to ⁇ ⁇ ⁇ and I ⁇ decreases.
- C For dihydroxybenzene, such as catechol, resorcin, and hydroquinone. These are added for the purpose of suppressing the adhesion to ⁇ , 0, and the paste, and suppressing the paste cracking during reflow soldering. When the addition amount is large, the solderability decreases, so that 0.1 to 1.0 parts by weight is an appropriate amount. When the amount exceeds the upper limit, the solderability decreases, and when the lower limit is broken, I ⁇ 0 is obtained. Adhesiveness ⁇ The effect of suppressing paste cracking during reflow soldering cannot be obtained.
- Antifoaming agents include acrylics and silicones, but the appropriate amount of addition is 0.05 to 0.3 parts by weight. If the foam exceeds the upper limit, the adhesion to I ⁇ and I0 decreases.
- the ratio of butyl carbitol noacetylaceton by weight is preferably 9.5 to 8.0 / 0.5 to 2.0, and the amount of addition can be used for screen printing.
- the addition amount that adjusts the paste to the viscosity is sufficient. If the acetylacetonate ratio falls below the lower limit, the wettability with ⁇ ⁇ ⁇ and 10 during paste printing decreases, and if the ratio exceeds the upper limit, the solvent volatilizes quickly during screen printing and printability increases. descend.
- Example 19 and Comparative Example 107 of the composition (parts by weight) shown in Table 1 were weighed into an appropriate container, and they were kneaded with a roll mill for 20 minutes to obtain a paste (conductive paint). . The following tests were carried out for each paste, and the results are shown in Table 1 below. The curing condition temperature in each test was maintained within the range of the standard curing temperature soil 20 for each paste.
- ⁇ 100% of the coating area of the paste is uniformly wetted with solder.
- Each base was printed 100 times on a glass epoxy substrate using a 180-mesh screen, and the printability was examined.
- Printing can be performed without any change in paste viscosity during printing.
- Silver plating copper powder Silver plating amount 11% by weight
- each of the examples has a rating of ( ⁇ ) that can withstand use in all of the tests, while the comparative example has a (X) rating in the pull strength or gray test.
- ⁇ a rating of ( ⁇ ) that can withstand use in all of the tests
- X a rating in the pull strength or gray test.
- the present invention is configured as described above, in a conventional silver paste using an epoxy resin binder, good adhesion and solderability can be obtained unless the curing is controlled with high precision. Can be achieved, and under the curing conditions of standard curing temperature ⁇ 20 ° C, various properties such as good conductivity, adhesion, and solderability can be obtained, which can significantly improve productivity. .
