Problems solved by technology

After the solvent in the ink volatilizes, what remains in the printed matter are mainly pigments, resins and additives. If the printed matter is used for food and pharmaceutical packaging, once it is accidentally in direct contact with food, it will be damaged due to the oil, alcohol and other substances in the food. The ester may dissolve the resin in the ink, and the food may be contaminated by the resin, which will have a huge impact on health after eating, and the ink on the discarded packaging is difficult to degrade naturally due to the resin, which also has a negative impact on the ecological environment. a major threat
[0003] At present, most of the binders in ordinary inks are made of non-degradable resin materials, which are harmful to the environment and food, and generally have high production costs, which are neither economical nor environmentally friendly; in addition, although there are some degradable Ink binder, but the polymer resin material used has a wide particle size distribution and poor uniformity, and the prepared ink has poor performance

Embodiment 1

[0028] This embodiment provides a biodegradable green printing ink binder, which includes polylactic acid microspheres with an average particle size of 5 μm.

[0029] The raw material of polylactic acid microspheres is lactic acid, which can be obtained by fermentation of starch extracted from corn, wheat, cassava and other plants. Therefore, polylactic acid has significant environmental friendly characteristics in the whole cycle of synthesis, manufacture, use and disposal , At the same time, because the raw material of polylactic acid microspheres can be extracted from natural plants, it can get rid of the dependence on petroleum to the greatest extent, and has outstanding resource renewability.

[0030] The ink vehicle described in this embodiment has a uniform particle size, so that the ink material containing the ink vehicle has an excellent developing effect.

[0031] This embodiment also provides a method for preparing the biodegradable green printing ink binder, which ...

Embodiment 2

[0037]This embodiment provides a biodegradable green printing ink binder, which includes polylactic acid microspheres with a particle size of 8 μm.

[0038] The ink vehicle described in this embodiment has a uniform particle size, so that the ink material containing the ink vehicle has an excellent developing effect.

[0039] This embodiment also provides a method for preparing the biodegradable green printing ink binder, which includes the following steps:

[0040] S1. Preparation of polylactic acid seed microspheres, dehydration condensation of lactic acid aqueous solution at 240° C. to obtain polylactic acid seed microspheres.

[0041] S2. Prepare polylactic acid microspheres, mix the polylactic acid seed microspheres with crosslinking agent, initiator, and emulsifier in proportion to obtain a premix, add a stabilizer to the premix, and perform a swelling reaction. Obtain polylactic acid microsphere ink binder with controllable particle size, such as figure 1 shown. In t...

Embodiment 3

[0045] This embodiment provides a biodegradable green printing ink binder, which includes polylactic acid microspheres with a particle size of 8 μm.

[0046] The ink vehicle described in this embodiment has a uniform particle size, so that the ink material containing the ink vehicle has an excellent developing effect.

[0047] This embodiment also provides a method for preparing the biodegradable green printing ink binder, which includes the following steps:

[0048] S1. Prepare polylactic acid seed microspheres, dehydrating and condensing the lactic acid aqueous solution at 200° C. to obtain polylactic acid seed microspheres;

[0049] S2. Prepare polylactic acid microspheres. After mixing the polylactic acid seed microspheres with crosslinking agent, initiator, and emulsifier in proportion, a premix is ​​obtained. Add an appropriate amount of stabilizer to the premix, and the swelling reaction , to obtain polylactic acid microsphere ink binder with controllable particle size...

Abstract

The invention discloses a biodegradable green printing ink binder, ink and a preparation method thereof. The ink binder comprises polylactic acid microspheres with an average particle diameter of 5-10mu m, the adopted polylactic acid microspheres have narrow particle diameter distribution, the ink added with the ink binder has excellent developing effect, and the technical problems of high toner charge, large toner adsorption force on a carrier, difficulty in participating in development and easy generation of photocopying defects due to too small particle diameter of the binder can be solved.The gloss and drying performance of the ink are improved, and the subsequent ink has good coloring effect when printed on the surface of the printing stock. The ink containing the ink binder has goodenvironmental friendliness, renewable resources, low production cost, little environmental pollution and high market value.

Description

technical field [0001] The invention belongs to the technical field of ink, and relates to an ink additive, an ink containing the additive and a preparation method thereof, in particular to a biodegradable green printing ink binder, an ink containing the binder and its preparation method. Background technique [0002] In recent years, with the rapid development of my country's national economy, the printing and packaging industry has developed rapidly, which has led to the rapid growth of printing inks. The main components of inks are pigments, resin binders and additives. The proportion of pigment in the composition of ink is about 10%-20%, which determines the color, tinting strength and chroma of the ink, as well as acid and alkali resistance, heat resistance and other properties. Resin binder accounts for about 70%-80% in the ink, mainly plays the role of dispersing pigments and additives, can help the ink form a uniform thin layer after printing, and protect the pigmen...
