Anti-bright trace and high temperature resistant resin composition for SD card electronic mylar

Abstract

The invention discloses an anti-bright trace and high temperature resistant resin composition for SD card electronic mylar. The resin composition is prepared from the following raw materials by weight: 5-15 parts of polycarbonate, 5-15 parts of PBT, 2-9 parts of ABS, 0.5-5 parts of alkyd modified organosilicon resin, 2-9 parts of nitrocotton resin, 0.5-4 parts of a dispersing agent, 0.5-3 parts of a defoaming agent, 0.5-3 parts of a leveling agent, 2-9 parts of Mitsubishi MA-75 carbon black, 5-15 parts of copper chromite black, 1-5 parts of inorganic iron black, 5-15 parts of filler, 5-11 parts of cyclohexanone, 5-15 parts of propylene glycol monoethyl ether acetate, 15-22 parts of isophorone, 0.5-4 parts of dibasic ester, and 0.5-3 parts of silicon dioxide. According to the resin composition provided by the invention, the solvent volatilization rate is adjusted through coordination of solvents with different doses, ink can dry completely, and no trace is left during pressing and sticking patches, under the synergistic effect of all the components, especially five resins, the ink side can be smooth, high in hardness, and traceless during pressing and sticking patches.

Description

technical field [0001] The invention belongs to the technical field of inks, and in particular relates to an electronic Mylar anti-bright marks and high temperature resistant resin composition for SD cards and a preparation method thereof. Background technique [0002] Mylar chips generally refer to die-cutting (DIECUT) punched into sheets according to the drawing requirements or specified. Mylar has two kinds of metal and non-metal. Metal Mylar is commonly used copper foil Mylar, aluminum foil Mylar, the main function is to conduct electricity; non-metal Mylar is insulating, common materials are PC, PET, used for Surface protection of membrane switches or electrical and electronic products, or partial insulation. There are many colors of Mylar tablets, commonly used are transparent, white, black, other colors can be printed according to specified requirements. Mylar sheet has the characteristics of high dielectric strength, high withstand voltage, resistance to moisture, ...

AI Technical Summary

Problems solved by technology

[0003] In the process of ordinary ink printing on Mylar, there is a process of printing glue on the ink, and then attaching a small piece of protective film, and there will be bright marks around the small stickers, which will seriously affect the quality of printing and electronic Mylar.
