Embodiment 1-1

[0029] Nitrogen was used to flush the reaction bottle, and 65.13 grams (32.56 mmol) of L-200 (purchased from HUNTSMAN), 10 grams (43.42 millimoles) of 1,6-hexanediol epoxy resin (purchased from Changchun Chemical Industry), 4.21 grams (32.56 millimoles) of octylamine (purchased from Aldrich) In the reaction flask, mechanically stirred and heated to 120° C., and then reacted for 4 hours. The above reaction is shown in formula 6.

[0030]

[0031] Cool down to 70°C afterwards, add 13.04 grams (130.26 mmol) of cyclosuccinic anhydride, react at 70°C for 12 hours, then heat up to 110°C for 3 hours to obtain a comb-like (comb-like) polymer ( Yield 99%, yellow liquid). The molar ratio of above-mentioned reactant is as follows: 1,6-hexanediol epoxy resin: octylamine: L-200: cyclosuccinic anhydride = 4:3:3:12. The above reaction is shown in formula 7.

Embodiment 1-2

[0036] Similar to Example 1-1, the difference is that R 3 -NH 2 Depend on L-200 is replaced by L-100, its structure is shown in Formula 8.

[0037]

[0038] The relevant spectral data are as follows: 1 H NMR (DMSO-d 6 , δ, ppm): 0.84(t), 1.02(m), 1.18(d), 1.22(b), 1.46(s), 2.40(s), 2.45(s), 3.23(s), 3.40~3.50( m), 4.97(d), 12.05(s). 13 CNMR (DMSO-d 6 , δ, ppm): 14.1, 17.2, 22.3, 25.6, 28.8, 28.9, 29.3, 31.4, 58.2, 69.8~70.7(m), 71.5, 74.4, 173.7(C=O).IR(KBr): 3469cm -1 (acid O-H stretch), 2921, 2870cm -1 (alkyl C-H stretch), 1730cm -1 (ester stretch), 1640cm -1 (C=O stretch)), 1104cm -1 (C-O-C stretch).

Embodiment 1-3

[0040] Similar to Example 1-1, the difference is that R 3 -NH 2 Depend on L-200 is replaced by L-300, its structure is as formula 9.

[0041]

[0042] The relevant spectral data are as follows: 1 H NMR (DMSO-d 6 , δ, ppm): 0.84(t), 1.02(d), 1.11(d), 1.23(b), 1.47(s), 2.40(s), 3.23(s), 3.32(s), 3.36~3.54( m), 5.07(d), 11.86(s). 13 C NMR (DMSO-d 6 , δ, ppm): 14.1, 17.3, 22.3, 28.2, 28.8, 28.9, 29.3, 31.4, 58.2, 67.9, 69.8~70.3(m), 71.5, 74.3, 74.4, 173.8(C=O).IR(KBr) : 3510cm -1 (acid O-H stretch), 2910, 2870cm -1 (alkyl C-H stretch), 1730cm -1 (ester stretch), 1640cm -1 (C=O stretch), 1110cm -1(C-O-C stretch).

Description

technical field [0001] The present invention relates to dispersants, and more particularly to their composition. Background technique [0002] Metal micropowder dispersion is the most difficult to disperse and stabilize metal micropowder because of its strong cohesive force, easy aggregation, high density, and easy sedimentation. In particular, if the fine metal powder is used as a conductive paste, the amount of the fine metal powder, organic dispersant, and additives will affect the conductivity of the conductive coating. What's more, if the metal fine powder is used as a low-viscosity (4-20cps, 25°C) inkjet printing ink, how to make the metal fine powder have excellent dispersibility and overcome gravity sedimentation to have high dispersion stability and high conductivity at the same time , where the dispersant plays a key role. However, there is currently no dispersant technology and products for the dispersion of conductive metal powders, and the required dispersant ...
