FLAME-RETARDANT CONDUCTIVE PASTE AND METHOD FOR PRODUCING SAID FLAME-RETARDANT CONDUCTIVE PASTE

WIPO Patent Application WO/2021/111675

A1

[Problem] To provide a flame-retardant conductive paste which is capable of forming a dried coating film that exhibits excellent flame retardancy such that the dried coating film does not catch fire even if there is an outbreak of fire in the vicinity thereof, or such that even in cases where the dried coating film caught fire, the fire is immediately put out, while having excellent electrical conductivity and high adhesion to a base material, thereby being not susceptible to separation from the base material, and which is suitable for use in an electrode of a capacitor. [Solution] A flame-retardant conductive paste which contains flake-like silver particles, a resin, a flame retardant and an organic solvent, wherein: the solid content that is composed of the flake-like silver particles, the resin and the flame retardant is from 40% by weight to 90% by weight; the content of the flake-like silver particles in the solid content is from 80% by weight to 95% by weight; the weight ratio of the resin to the flame retardant is from 91:9 to 40:60; and the flame retardant is composed of a phosphoric acid ester compound.
