Problems solved by technology

[0003] In an existing preparation process of electronic Mylar film, it is necessary to use three-layer PET material for lamination treatment within 5 minutes at about 170°C, but the current ink cannot meet the requirements, and it needs to be pasted after lamination treatment. 3M glue, and the existing ink is difficult to guarantee that it will not be corroded by 3M glue at about 160°C for 1 minute, and it is also difficult to ensure good adhesion to the substrate, so it is necessary to design an electronic Mylar ink with higher high temperature resistance

Abstract

The invention discloses a high hardness and high temperature resistant electronic mylar ink for television sets. The electronic mylar ink comprises a resin component and a curing agent, wherein the resin component is prepared from the following raw materials by weight: 2-10 parts of PBT resin, 11-19 parts of polyurethane, 2-9 parts of Toyobo 240 polyester resin, 5-15 parts of amino resin, 6-15 parts of cyclohexanone, 11-19 parts of dibasic ester, 11-19 parts of isophorone, 6-15 parts of propylene glycol methyl ether acetate, 2-8 parts of Cabot M-L carbon black, 2-8 parts of copper chromite black, and 2-8 parts of filler. The ink provided by the invention cannot be glued away within 5min at 190DEG C, under the circumstance of a rapidly increasing ink surface hardness, the ink cannot be molten by scalding, and has good printing adaptability; the ink cannot be corroded by 3M glue at 180DEG C in 1min, has the advantages of alcohol resistance, high surface hardness and good adhesion with a substrate, and can meet various printing requirements of electronic mylar.

Description

technical field [0001] The invention belongs to the technical field of inks, and in particular relates to an electronic Mylar ink for high-hardness and high-temperature-resistant TV sets and a preparation method thereof. Background technique [0002] Mylar sheet generally refers to die-cutting (DIECUT) according to the requirements of the drawing or specified punching into a sheet. There are two types of Mylar, metal and non-metallic. Metal Mylar sheets are commonly used for copper foil Mylar and aluminum foil Mylar. Membrane switch or surface protection of electrical and electronic products, or partial insulation. There are many colors of mylar sheets, commonly used are transparent, white, black, and other colors can be printed according to specified requirements. Mylar sheet has the characteristics of high dielectric strength, high voltage resistance, resistance to moisture, gas, high heat and chemical substances, low shrinkage, not easy to embrittle and wear-resistant. ...
