Example Embodiment
[0045] Example 1
[0046] The biodegradable green printing ink binder disclosed in the present invention includes the following components in parts by weight:
[0047] Vegetable oil: 5 parts of soybean oil, 1 part of isooctyl palmitate, 4 parts of palm oil, 3 parts of linseed oil, 3 parts of tung oil;
[0048] Resin: 20 parts of modified phenolic resin, 10 parts of dry long oil alkyd resin;
[0049] Excipients: 0.5 part of aluminum gelling agent, 0.1 part of antioxidant.
[0050] Among them, the modified phenolic resin is a rosin-modified diphenol-based propane resin; the dry long oil alkyd resin is selected as JC115 long oil alkyd resin.
[0051] A preparation method of biodegradable green printing ink binder includes the following steps:
[0052] S1: Take various raw materials in proportions by weight, mix the vegetable oil, and mix the resin;
[0053] S2: Add a catalyst to the mixed vegetable oil. The catalyst is anthraquinone. The catalyst is 2-6% by weight of the vegetable oil. Stir e...
Example Embodiment
[0057] Example 2
[0058] The difference from Example 1 is:
[0059] A biodegradable green printing ink binder, in parts by weight, including the following components:
[0060] Vegetable oil: 7 parts of soybean oil, 2.8 parts of isooctyl palmitate, 6.3 parts of palm oil, 5.6 parts of linseed oil, 5.6 parts of tung oil;
[0061] Resin: 23 parts of modified phenolic resin, 13.8 parts of dry long oil alkyd resin;
[0062] Excipients: 0.8 part of aluminum gelling agent, 0.5 part of antioxidant.
[0063] Among them, the modified phenolic resin is a rosin-modified diphenol-based propane resin and a rosin-modified p-tert-butyl phenolic resin with a weight part of 1:1.
[0064] At this time, the ratio of modified phenolic resin to dry long oil alkyd resin is 1:0.6.
[0065] The ratio of soybean oil, isooctyl palmitate and palm oil is 1:0.4:0.9.
[0066] The ratio of soybean oil, linseed oil and tung oil is 1:0.8:0.8.
[0067] A preparation method of biodegradable green printing ink binder includes t...
Example Embodiment
[0072] Example 3
[0073] The difference from Example 1 is:
[0074] A biodegradable green printing ink binder, in parts by weight, including the following components:
[0075] Vegetable oil: 9 parts of soybean oil, 3 parts of isooctyl palmitate, 8 parts of palm oil, 7 parts of linseed oil, 7 parts of tung oil;
[0076] Resin: 28 parts of modified phenolic resin, 18 parts of dry long oil alkyd resin;
[0077] Accessories: 2 parts aluminum gelling agent, 1 part antioxidant.
[0078] Among them, the modified phenolic resin is rosin-modified p-tert-butyl phenolic resin.
[0079] A preparation method of biodegradable green printing ink binder includes the following steps:
[0080] S1: Take various raw materials in proportions by weight, mix the vegetable oil, and mix the resin;
[0081] S2: Add a catalyst to the mixed vegetable oil, the catalyst is anthraquinone, the catalyst is 6% by weight of the vegetable oil, stir evenly, while raising the temperature to 230°C, add the resin in batches, and...
