Abstract

The invention provides anti-scraping corrosion-resistant ink which comprises, by weight parts, 55-68 parts of polyurethane modified epoxy-acrylate resin, 14-21 parts of gum dammar, 7-12 parts of polyterpene phenolic resin, 3-8 parts of butyl methacrylate, 4-9 parts of calcium lignosulfonate, 3-7 parts of nano silica, 1.8-3.4 parts of mica iron oxide, 3-6 parts of short carbon fiber, 2-5 parts of difenoconazole, 1-3.2 parts of coupling agent, 1.5-2.7 parts of flatting agent and 125-150 parts of solvent. After being dried, the prepared anti-scraping corrosion-resistant ink is high in hardness and adhesion and resistant to scraping. The anti-scraping corrosion-resistant ink is excellent in acid and alkali corrosion resistance testing performance, can meet the application requirements in the severe environment and is good in market prospect.

Description

technical field [0001] The invention belongs to the technical field of ink materials, and in particular relates to a scratch-resistant and corrosion-resistant ink and a preparation method thereof. Background technique [0002] Conductive ink, a paste ink made of conductive materials (gold, silver, copper and carbon) dispersed in a binder, commonly known as paste ink. It has a certain degree of conductive properties and can be used for printing conductive points or conductive lines. Gold-based conductive inks, silver-based conductive inks, copper-based conductive inks, and carbon-based conductive inks have been put into practical use for printed circuits, electrodes, electroplating bottom layers, keyboard contacts, and printed resistors. The existing conductive ink has low hardness after drying, is not scratch-resistant, and its acid, alkali and salt corrosion resistance is not good, so it cannot meet the application requirements of harsh environments.
