Problems solved by technology

With the increasing requirements of environmental protection, traditional thermosetting inks can no longer meet the requirements of environmental protection. Although high boiling point kerosene has been changed from high aromatic kerosene to low aromatic or even aromatic free kerosene in recent years, kerosene is a petrochemical product after all. , is a non-renewable resource
The thermosetting inks currently on the market are still traditional thermosetting inks based on petroleum solvents, and there is no environmentally friendly thermosetting offset printing ink without petroleum solvents.

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...

Abstract

The invention discloses plant-oil-based green heat-set ink. The ink is prepared from, by mass, 55-75% of binder, 10-25% of pigment, 0-5% of alkyd resin, 0-5% of plant oil, 0-1% of dispersing agent, 0-2% of wax, 0.5-2% of dryer retarder and 5-10% of plant oil derivative. The binder is prepared from, by mass, 35-45% of rosin modified phenolic resin, 20-35% of plant oil, 10-40% of plant oil derivative and 0-2% of gel. The plant-oil-based green heat-set ink has the set and drying speed the same as and even higher than that of ordinary heat-set ink, has excellent color and luster and is free of petroleum solvent, and lots of recyclable resources are used.

Description

Technical field [0001] The invention relates to the technical field of inks, in particular to a thermosetting ink. Background technique [0002] The drying form of ordinary thermosetting offset printing ink is a combination of osmotic fixation, oxidative polymerization and high temperature volatilization of some solvents: the ink is printed on the paper, the solvent penetrates into the pores of the paper, the resin is precipitated and fixed, and the binder is The dry vegetable oil and its chain polymers are cross-linked by oxidation to form macromolecules with a network structure. The printed matter passes through a high-temperature drying tunnel, using high-temperature volatilization of part of the solvent while accelerating the speed of oxidizing conjunctiva, completing solidification to form a solid ink film. The dry vegetable oils in traditional offset printing inks are mostly linseed oil, catalpa oil, tung oil and other dry vegetable oils. The dilution solvent is high-boilin...
