Embodiment 1

[0034]Prepare a frequency conversion speed regulating stirring and dispersing machine and a 1.5L stainless steel container, take 100g of isophorone, 220g of dibasic ester (DBE), and 200g of cyclohexanone into the container, start the mixer, and adjust the speed to 100 rpm. Slowly add 360g of polyester resin (molecular weight: 19000, Tg: 60), adjust the speed of the mixer to 600 rpm, and stir for 20 minutes. Adjust the speed of the mixer to 1500 rpm. If the temperature in the container exceeds 80°C, the speed of the mixer can be further reduced. The temperature of the container during the whole process does not exceed 80°C. After stirring for 2 hours, visually check whether there is any unmelted resin block in the container. If there is no resin liquid fineness with a scraper fineness meter, if there is no melted resin in the container, continue stirring until it is completely melted Finally, after passing the test with a scraper fineness meter, add 120 g of butyl oxalate aceta...

Embodiment 2

[0036] Prepare a frequency conversion speed regulating stirring dispersing machine and a 1.5L stainless steel container, take 90g of isophorone, 200g of dibasic ester (DBE), and 190g of cyclohexanone into the container, start the mixer, and adjust the speed to 100 rpm. Slowly add 370g of polyester resin (molecular weight: 18000, Tg: 72), adjust the speed of the mixer to 600 rpm, and stir for 20 minutes. Adjust the speed of the mixer to 1500 rpm. If the temperature in the container exceeds 80°C, the speed of the mixer can be further reduced. The temperature of the container during the whole process does not exceed 80°C. After stirring for 2 hours, visually check whether there is any unmelted resin block in the container. If there is no resin liquid fineness with a scraper fineness meter, if there is no melted resin in the container, continue stirring until it is completely melted Finally, after passing the test with a scraper fineness meter, add 150 g of butyl oxalate acetate (...

Embodiment 3

[0038] Prepare a frequency conversion speed regulating stirring dispersing machine and a 1.5L stainless steel container, take 80g of isophorone, 190g of dibasic ester (DBE), and 180g of cyclohexanone into the container, start the mixer, and adjust the speed to 100 rpm. Slowly add 380g of polyester resin (molecular weight: 15000, Tg: 80), adjust the speed of the mixer to 600 rpm, and stir for 20 minutes. Adjust the speed of the mixer to 1500 rpm. If the temperature in the container exceeds 80°C, the speed of the mixer can be further reduced. The temperature of the container during the whole process does not exceed 80°C. After stirring for 2 hours, visually check whether there is any unmelted resin block in the container. If there is no resin liquid fineness with a scraper fineness meter, if there is no melted resin in the container, continue stirring until it is completely melted Finally, after passing the test with a scraper fineness meter, 170 g of butyl oxalate acetate (DBGA...

Abstract

The invention relates to multifunctional environment-friendly silk-screen transfer printing ink. The invention relates to matrix resin liquid and a preparation method thereof. The resin liquid is prepared from 360 to 400g of polyester resin, 60 to 100g of isophorone, 180 to 220g of dibasic ester (DBE), 150 to 200g of cyclohexanone and 120 to 190g of butoxyethyl oxalate (DBGA).

Description

technical field [0001] The invention relates to a screen printing pad printing ink composition, in particular to a multifunctional and environment-friendly screen printing pad printing ink and a preparation method thereof. Background technique [0002] Various countries and regions around the world continue to introduce a variety of environmental protection regulations for various industrial products, and screen printing pad printing inks are widely, even essential, used on various industrial products, and they are mainly controlled Environmental protection of screen printing pad printing ink is also the direction of development. [0003] The European Union has formulated ROHS2.0 (2011 / 65 / EU) regulations for products exported to Europe, EN71-3 (1994, 2000) EU toy safety regulations for toys, REACH regulations, PAHS regulations for polycyclic aromatic hydrocarbons (Afps Gs 2019: 01PAK), phthalates control, bisphenol A control, halogen control, PFOS / PFOA control, hexabromodod...
