Embodiment 1
[0018] A vegetable oil-based green thermosetting ink is prepared from the following ingredients in mass fractions: binder 65%, pigment 20%, alkyd resin 2.5%, vegetable oil 2.5%, dispersant 0.5%, wax 0.5%, Anti-drying agent 1.0% and vegetable oil derivatives 8%;
[0019] The binder is prepared from the following ingredients in mass fractions: 38~42% rosin modified phenolic resin, 25~30% vegetable oil, 25~35% vegetable oil derivative and 0.8~1.2% gelling agent Prepared.
[0020] The rosin-modified phenolic resin is two kinds of phenolic resins, one is a high-viscosity, high-structure, low-solubility resin, which provides the body bone for the ink, and has anti-flight performance, excellent abrasion resistance, dot definition, and printing gloss. The other is a resin with low viscosity, low structure and medium solubility, which provides excellent gloss, leveling and pigment wettability for ink.
[0021] The alkyd resin is a long oil alkyd resin, and the alkyd resin is an alkyd resin ...
Embodiment 2
[0030] A vegetable oil-based green thermosetting ink is prepared from the following ingredients in mass fractions: 60% binder, 25% pigment, 2% alkyd resin, 2% vegetable oil, 0.5% dispersant, 1.5% wax, Anti-drying agent 1.5% and vegetable oil derivative 7.5%;
[0031] The binder is prepared with the following components in mass fraction: 40% rosin modified phenolic resin, 30% vegetable oil, 28% vegetable oil derivative and 2% gelling agent.
[0032] The remaining components are the same as in Example 1.
Embodiment 3
[0034] A vegetable oil-based green thermosetting ink is prepared with the following mass fractions of ingredients: 70% binder, 15% pigment, 3% alkyd resin, 2% vegetable oil, 0.5% dispersant, 0.5% wax, Anti-drying agent 1.0% and vegetable oil derivatives 8%;
[0035] The binder is prepared from the following components in mass fractions: 35% rosin modified phenolic resin, 35% vegetable oil, 29% vegetable oil derivative and 1% gelling agent.
[0036] The remaining components are the same as in Example 1.
[0037] The preparation methods of the above three embodiments include the following steps:
[0038] 1) Ingredients, prepare the relevant mass parts of materials according to the ink formula;
[0039] 2) Prepare the binder, add vegetable oil and rosin-modified phenolic resin into the reactor, heat up and stir, add vegetable oil derivatives after the temperature reaches 200°C for one hour, then add the gelling agent after cooling to below 160°C, then Warm up to 180°C for one hour, disch...
