Problems solved by technology

However, the drying speed of some existing printing inks is too slow, which often causes the backside to be smeared and stuck to the page during printing.
There are also some printing inks with poor adhesion, which are prone to uneven printing and deinking, which seriously affect the printing quality.
Moreover, these inks usually do not have heat resistance, which seriously affects the application range of the ink

Abstract

The invention discloses a friction-resistant solvent-resistant ink, characterized by comprising the following raw materials in parts by weight: 30-50 parts of titanium dioxide, 30-50 parts of vinisol,30-50 parts of lignin modified phenolic resin, 20-39 parts of saturated polyester resin, 20-30 parts of isoamyl acetate, 2-4 parts of starch phosphate, 26-39 parts of isopropanol, 2-9 parts of dipropylene glycol dimethyl ether, 1-3 parts of energy stone, 2-3 parts of magnet, 4-6 parts of hydrotalcite, 1-1.2 parts of sulfonated ricinoleic acid, 1-1.5 parts of polysorbate, 1-2 parts of butanone oxime, 1-2 parts of iron octoate and 60-65 parts of water. The ink obtained by the invention has faster drying speed, good adhesion and excellent heat resistance, is solvent-free and volatile, and has little harmfulness to human body, in particular, the ink obtained by using energy stone, magnet and hydrotalcite as fillers is far better than that of the ink obtained by using calcium carbonate filler.

Description

technical field [0001] The invention relates to graphite, in particular to a friction-resistant and solvent-resistant ink. Background technique [0002] Ink is a substance used to form graphic information in the printing process, which directly determines the tone, color, and clarity of the image on the printed matter, so it plays a huge role in the printing process. However, the drying speed of some existing printing inks is too slow, which often causes phenomena such as back smearing and page sticking during printing. There are also some printing inks with poor adhesion, which are prone to uneven printing and deinking, which seriously affect the printing quality. Moreover, these inks usually do not have heat resistance, which seriously affects the application range of the ink. Therefore, it is urgent to design an ink with fast drying speed, good adhesion and strong heat resistance. Contents of the invention [0003] In order to solve the above technical problems, the ...
