Abstract

The invention discloses an antioxidant low-corrosion low-temperature-curing conductive ink. A formula of the antioxidant low-corrosion low-temperature-curing conductive ink comprises, by weight, 30 to75 parts of a resin intermediate, 4 to 25 parts of a solvent, 0.5 to 5 parts of an antioxidant, 10 to 50 parts of silver powder and 0.5 to 5 parts of an auxiliary agent; the resin is hydroxyl or carboxyl modified ternary vinyl chloride-vinyl acetate resin, the molecular weight ranges from 15000 to 65000, and K ranges from 35 to 60; the solvent is selected from one or more of diethylene glycol butyl ether acetate, diethylene glycol butyl ether, ethylene glycol, ethylene glycol butyl ether acetate, ethylene glycol butyl ether, 1, 4-butanediol, triethylene glycol butyl ether, tripropylene glycol, diethylene glycol, tripropylene glycol butyl ether, 3-methoxy-3-methyl-1-butanol and dipropylene glycol methyl ether; and the resin intermediate is a resin diluted by the solvent. The phenomenon that the surface of a conductive ink paint film is gradually yellowed is effectively changed, the bottom biting defect of conductive ink on plastic films such as PVC, PC, ABS and PMMA can be prevented, and the product quality is effectively improved.

Description

technical field [0001] The invention relates to a conductive ink, in particular to an oxidation-resistant and low-corrosion low-temperature curing conductive ink. Background technique [0002] Conductive inks cured at low temperature are widely used in display screens, membrane switches, flexible circuits and other electronic components, making it possible to make electronic products thinner and smarter. However, with the development of electronic products such as foldable mobile phones and curved TVs that have been vigorously promoted on the market in recent years, there is a higher demand for the performance of flexible screens and flexible circuits, which in turn requires the conduction that plays a key role in such electronic components. Inks put forward higher performance requirements. [0003] Traditional conductive ink or conductive silver paste is usually printed on such as PET (polyethylene terephthalate plastic), silica gel, PP (polypropylene plastic), PE (polyeth...
