Embodiment 1

[0028] A production process of wear-resistant offset printing ink, it comprises the following steps:

[0029] Step 1, heating the base ink to 75°C;

[0030] Step 2, then add wax powder to the 75°C base ink prepared in step 1, and control the adding speed of the wax powder. During the process of adding wax powder to the base ink, it needs to stir at a low speed throughout the process. After the wax powder is added , to obtain the mixture; in the present embodiment, the wax powder accounts for 5% of the mass percentage of the base ink; in the present embodiment, the addition speed of the wax powder is controlled to be 1.5kg / min; in the present embodiment, the speed of low-speed stirring is 200r / min. min;

[0031] Step 3: After adding the wax powder, continue to control the temperature of the mixture to 75° C., and then stir the mixture at a high speed for 40 minutes to obtain a wear-resistant offset printing ink. In this embodiment, the speed of high-speed stirring is 1100 r / m...

Embodiment 2

[0034] A production process of wear-resistant offset printing ink, it comprises the following steps:

[0035] Step 1, heating the base ink to 70°C;

[0036] Step 2, then add wax powder to the 70°C base ink prepared in step 1, and control the adding speed of the wax powder. During the process of adding wax powder to the base ink, it needs to stir at a low speed throughout the process. After the wax powder is added , to obtain the mixture; in the present embodiment, the wax powder accounts for 2% by mass of the base ink; in the present embodiment, the addition speed of the wax powder is controlled to be 1kg / min; in the present embodiment, the speed of low-speed stirring is 150r / min ;

[0037] Step 3, after adding the wax powder, continue to control the temperature of the mixture to 70°C, and then stir the mixture at high speed for 30 minutes; in this embodiment, the speed of high speed stirring is 1200r / min;

[0038] Step 4: After the mixture in Step 3 is stirred at a high spe...

Embodiment 3

[0041] A production process of wear-resistant offset printing ink, it comprises the following steps:

[0042] Step 1, heating the base ink to 80°C;

[0043] Step 2, then add wax powder to the 80°C base ink prepared in step 1, and control the adding speed of the wax powder. During the process of adding wax powder to the base ink, it needs to stir at a low speed throughout the process. After the wax powder is added , obtain mixture; In the present embodiment, the mass percentage that wax powder accounts for base ink is 10%; In the present embodiment, the addition speed of controlling wax powder is 3kg / min; In the present embodiment, the speed of low-speed stirring is 250r / min ;

[0044] Step 3: After adding the wax powder, continue to control the temperature of the mixture to 80° C., and then stir the mixture at a high speed for 60 minutes to obtain a wear-resistant offset printing ink. In this embodiment, the speed of high-speed stirring is 900 r / min.

Abstract

The invention relates to the technical field of ink production, in particular to a production technology of wear-resistant offset ink. The production technology of the wear-resistant offset ink comprises steps as follows: Step 1, base ink is heated to a certain temperature; Step 2, then wax powder is added to the base ink at the certain temperature, the adding speed of the wax powder is controlled, low-speed stirring is required in the whole process when the wax powder is added to the base ink, and a mixture is obtained after addition of the wax powder; Step 3, after addition of the wax powder, the temperature of the mixture is controlled continuously, then the mixture is stirred at the high speed for a period, and the wear-resistant offset ink is obtained. The production technology of the wear-resistant offset ink has the advantages of simple production technology and low equipment energy consumption, the dispersion degree of the wax powder in the base ink can be increased, and the wear resistance of the prepared wear-resistant offset ink is better.

Description

technical field [0001] The invention relates to the technical field of ink production, in particular to a production process of wear-resistant offset printing ink. Background technique [0002] Offset printing ink In order to endow the printed ink with abrasion resistance, a certain amount of wax component needs to be added when making offset printing ink. In the prior art, the production process of offset printing ink is to first stir and mix wax powder with varnish, vegetable oil and mineral oil, then grind to prepare wax slurry or wax paste, and then make the prepared wax slurry or wax paste The paste is directly added to the base ink for simple stirring to disperse to prepare offset printing ink. However, in the prior art, this production process of first preparing wax slurry or wax paste and then adding it to the base ink to prepare offset printing ink, because the wax slurry is slurry, and the wax paste is paste, and because the wax in the ink The degree of dispersio...
