Problems solved by technology

[0003] When the thermal printing paper is used for students to print wrong questions, the coating of different color inks is used to give the thermal printing paper different colors. Different colors can make students more eye-catching, and can make corresponding distinctions for knowledge points; the existing After the ink is printed on the paper, it needs a long drying time. When the thermal printing paper is printed, it is necessary to ensure that the ink is completely dry, so as to prevent the printer’s print head from sticking to the ink on the paper, but the long drying time is easy Affect the production efficiency of the enterprise

[0034] Preparation example of oil-absorbing xerogel

[0035] Lignin in the following raw materials was purchased from Pand (Shanghai) International Trading Co., Ltd.; isocyanate was purchased from Shandong Dada Chemical Co., Ltd., model PM200; tetrahydrofuran was purchased from Jinan Pulaihua Chemical Co., Ltd.; triethanolamine was purchased from Jinan Pulaihua Chemical Co., Ltd. Co., Ltd.; turpentine was purchased from Jinan Huijinchuan Chemical Co., Ltd.; other raw materials and equipment are all commercially available.

preparation example 1

[0036] Preparation Example 1: Oil-absorbing dry gel was prepared by the following method:

[0037] Ⅰ Weigh 0.1g lignin and 0.8g isocyanate and dissolve them in 8g tetrahydrofuran, then add 40g triethanolamine, stand at room temperature for 5h to obtain the initial gel;

[0038] II. The primary gel prepared in I was dried to constant weight at normal temperature and pressure to obtain oil-absorbing dry gel.

preparation example 2

[0039] Preparation Example 2: Oil-absorbing dry gel was prepared by the following method:

[0040] Ⅰ Dissolve 0.25g lignin and 0.2g isocyanate into 10g tetrahydrofuran, then add 10g triethanolamine, and leave it for 4h at room temperature to obtain the initial gel;

[0041] II. The primary gel prepared in I was dried to constant weight at normal temperature and pressure to obtain oil-absorbing dry gel.

Abstract

This application relates to the field of ink technology, and specifically discloses an ink for thermal printing paper and a preparation method thereof; the ink contains a mass ratio of 2: (0.5-1.5): (0.5-1.5): (0.1-0.5) The mixed ink, white ink, diluent and desiccant; the mixed ink is made by mixing two or more of cyan ink, magenta ink and yellow ink; the preparation method is: S1, weigh mixed ink, white ink, After the diluent is mixed, stir at a speed of 500-800r / min for 2-5min, then add a desiccant and continue stirring for 30-90s to obtain a finished ink; it has the advantages of fast drying speed and rich colors.

Description

technical field [0001] The present application relates to the technical field of ink, and more particularly, to an ink for thermal printing paper and a preparation method thereof. Background technique [0002] Thermal printing paper is also known as thermal copy paper and thermal recording paper. Its manufacturing principle is to coat a layer of "thermal paint" on high-quality base paper, and use thermal printers for printing. It is widely used in Recording materials in medical and measurement systems can also be used to print wrong questions by students. [0003] When the thermal printing paper is used for students to print wrong questions, the thermal printing paper is given different colors by coating with different colors of ink. Different colors can make students more eye-catching, and can make corresponding differences for knowledge points; the existing After the ink is printed on the paper, it needs a long drying time. When the thermal printing paper is printing, it ...
