Low-temperature-resistant elastic conductive paste and preparation method and application thereof

The invention relates to the technical field of new materials, in particular to low-temperature-resistant elastic conductive paste and a preparation method and application thereof. The conductive paste comprises 1 to 10 wt% of a curing agent and 4.5 to 13 wt% of composite resin. Wherein the composite resin comprises first resin and second resin in a mass ratio of (0.5-3): (4-10); the first resin is selected from one or more of polyester resin, polyurethane resin, epoxy resin, acrylic resin, phenolic resin, alkyd resin, organic silicon resin, vinyl chloride-vinyl acetate resin and polyimide resin; and the second resin is a thermoplastic elastomer. According to the low-temperature-resistant elastic conductive paste provided by the invention, a conductive circuit formed by using the conductive paste is relatively small in resistance change and excellent in rebound resilience under the condition of 20% repeated stretching, and the resistance change rate of the conductive circuit in a high-low temperature impact t
