Problems solved by technology

For the new type of environmentally friendly water-based ink for plastic printing, the diluted pH value control agent is deionized water plus a small amount of ammonia water, and the boiling point of water is high, and the heat volatilization requirements are also high, so the drying speed of water-based ink depends on There are two ways: one is volatile drying, the other is absorbing drying, and the plastic film is a non-absorbing substrate, so the volatile drying method can only be used to help the water-based ink dry and solidify quickly, otherwise In the case of a certain fast printing, the water-based ink is not completely dry and the anti-sticking phenomenon of the film is unimaginable.

Embodiment 1

[0023] Water-based acrylic quick-drying agent, including by volume:

[0024] 15% zinc oxide solution: 15 parts

[0025] 28% ammonia water: 2 parts

[0026] 3) Deionized water: 15 parts

[0027] 4) Water-based acrylic emulsion (Argentina diransa, model: SF) with Tg value (-30℃~-50℃): 68 parts

[0028] Preparation method:

[0029] The first step: prepare the zinc oxide dissolving liquid of 15% content: because zinc oxide is insoluble in water, therefore, after dissolving 112g ammonium carbonate with 154g water earlier for 3~5 minutes, ammonium carbonate is dissolved in water. Then add 75g zinc oxide again, become opaque solution after 2~3 minutes, then add the ammoniacal liquor of 159g 28% concentration in the solution, obtain the zinc oxide solution of the 15% content of 500g after 3~5 minutes.

[0030] Step 2: Prepare water-based acrylic quick-drying agent

[0031] This production process must pay attention to the order of the entire addition process, otherwise, it will l...

Embodiment 2

[0037] Water-based acrylic quick-drying agent, including by volume:

[0038] 12% zinc oxide solution: 12 parts

[0039] 28% ammonia water: 1 part

[0040] 3) Deionized water: 12 parts

[0041] 4) Water-based acrylic emulsion with Tg value (-30℃~-50℃): 65 parts

[0042] Preparation method:

[0043] The first step: prepare 500 g of zinc oxide solution with a content of 12%: refer to Example 1 for the method.

[0044] Step 2: Prepare water-based acrylic quick-drying agent

[0045] This production process must pay attention to the order of the entire addition process, otherwise, it will lead to agglomeration and thickening.

[0046] Steps: 1. Take out 12 volumes of zinc oxide solution (12% zinc oxide content)

[0047] 2. Add 2 volumes of ammonia water (28% concentration) to the zinc oxide solution

[0048] 3. Add 12 volumes of deionized water

[0049] 4. Add 65 volumes of water-based acrylic emulsion to obtain a water-based acrylic quick-drying agent.

Embodiment 3

[0051] Water-based acrylic quick-drying agent, including by volume:

[0052] 18% zinc oxide solution: 20 parts

[0053] 28% ammonia water: 3 parts

[0054] 3) Deionized water: 18 parts

[0055] 4) Water-based acrylic emulsion with Tg value (-30℃~-50℃): 70 parts

[0056] Preparation method:

[0057] The first step: preparing a zinc oxide solution with a content of 18%: refer to Example 1 for the method.

[0058] Step 2: Prepare water-based acrylic quick-drying agent

[0059] This production process must pay attention to the order of the entire addition process, otherwise, it will lead to agglomeration and thickening.

[0060] Steps: 1. Take out 20 parts of zinc oxide solution (18% zinc oxide content)

[0061] 2. Add 3 parts of ammonia water (28% concentration) to the zinc oxide solution

[0062] 3. Add 18 parts of deionized water

[0063] 4. Add 70 parts of water-based acrylic emulsion to obtain a water-based acrylic quick-drying agent.

Abstract

The invention discloses a water based acrylic acid type quick-drying agent which comprises the following components in parts by volume: 12-20 parts of 12-18 percent zinc oxide solution, 1-3 parts of stronger ammonia water, 12-18 parts of deionized water and 65-70 parts of water based acrylic emulsion, wherein the Tg value of the acrylic emulsion is between -30 DEG C and -50 DEG C. The water based acrylic acid type quick-drying agent disclosed in the invention can be used in water based ink, especially water based ink for printing a plastic table. 2-5 percent of the water based acrylic acid type quick-drying agent can be added in a subsequent adding process of preparing the water based ion to ensure that the water based ink undergoes rapid transfer in a printing process and can generate arapid curing and drying effect in an oven drying channel at a temperature of 40-50 DEG C, and plays a role of preventing adhesion and improving wear resistance.

Description

technical field [0001] The invention relates to a water-based acrylic quick-drying agent, in particular to a water-based acrylic quick-drying agent for ink. It is used especially in environmentally friendly water-based inks for printing on plastics. Background technique [0002] For a long time, ink pollution has been the most serious problem in the printing industry. The annual output of ink in the world has exceeded 3 million tons. Solvent-based inks account for 30% to 40% on average, and the amount of organic solvents brought by inks worldwide is as high as 1 million tons per year, resulting in a huge waste of resources. Among them, organic solvents such as ethanol, butyl acetate, toluene, and xylene are often used. Most of it will be eliminated after drying, but the remaining part will still cause harm to the human body. Long-term contact will make the skin dry and rough. If it penetrates into the skin or blood vessels, it will endanger the human blood cells and hemat...
