Problems solved by technology

[0005] However, at present, the high-temperature-resistant ink used for jet printing has poor adhesion fastness to the substrate. After high-temperature cooking, the jet imprint will become unclear, and the batch number mark cannot be identified, which makes the effect of the printed product unsatisfactory.

Abstract

The invention discloses high-temperature-resistant ink containing modified resin. The high-temperature-resistant ink comprises components in parts by weight as follows: 20-30 parts of modified resin, 1-10 parts of polyethylene vinyl acetate, 3-8 parts of vinyl chloride-vinyl acetate resin, 2-6 parts of ethylene glycol monostearate, 1-5 parts of ethyl acetate, 5-10 parts of an antifoaming agent, 3-7 parts of an adhesion promoter, 1-6 parts of a matting agent, 1-10 parts of high-temperature-resistant aids and 30-40 parts of a solvent. The high-temperature-resistant ink is prepared from the modified resin, is applicable to a spraying printing technology and has good adhesion on products, clear print marks and good high-temperature resistance, cannot shed, fade or release substances harmful to a human body in the high-temperature steaming process and is applicable to the fields of food and medicine packaging.

Description

technical field [0001] The invention relates to the field of inks, in particular to a modified resin high temperature resistant ink. Background technique [0002] Continuous inkjet printing system (CIJ) is a relatively complex inkjet system, and its biggest advantage is that it can achieve high-speed printing when printing. [0003] According to the printing substrate of the marking information and the use environment, there are also different requirements for the ink used. For example, in many food packaging products, after the packaging is sealed, it is necessary to print the identification information, and in order to sterilize and make the finished product, it needs to be cooked at high temperature. In the high-temperature cooking process, it is required that the printed information cannot have obvious changes before and after cooking, which requires the ink to meet the requirement of not fading during the high-temperature cooking process. [0004] High temperature res...
