CONDUCTIVE INK COMPOSITIONS COMPRISING GOLD AND METHODS FOR MAKING THE SAME

NºPublicación: US2020157369A1 21/05/2020

Solicitante:

ELECTRONINKS INCORPORATED [US]

Resumen de: US2020157369A1

A particle-free gold-complex based ink is described wherein a gold carboxylate is complexed with an amine. Upon heating the solution, the gold cation catalyzes the oxidative amidation of the amine with the carboxylate to form a short chain or polymeric amide while simultaneously reducing the gold cation to metallic gold. This method is extremely versatile and allows for both the preparation of pure metallic gold films as well as polymer gold composites with unique properties.

Raw materials of the insulating varnish comprise polyol, acid anhydride, a neutralizing agent, a co-solvent, a water-based curing agent, water, diisocyanate and a chain extender. The polyol is composed of glycerol and neopentyl glycol. The acid anhydride is composed of phthalic anhydride and trimellitic anhydride. By means of mixing glycerol, neopentyl glycol, phthalic anhydride and trimellitic anhydride and causing a polycondensation reaction, a hydroxyl-terminated hyperbranched polyester is prepared. The hydroxyl-terminated hyperbranched polyester is reacted with diisocyanate, and then the neutralizing agent, the co-solvent, the chain extender and water are added and reacted. The water-based curing agent is then added and mixed to obtain the insulating varnish. The insulating varnish can prevent the transformer dipped with the water-based insulating varnish from being subjected to a secondary soldering at a high temperature of about 400°C, and can impart thereto soldering and conductive characteristics at an operating temperature of a plug-in circuit board, and can be further applied to a plug-in circuit board, streamlining process steps and saving energy.
