Two-component condensed type organic silicon sealant and preparation method thereof

The invention discloses a bi-component condensed type organic silicon sealant and a preparation method thereof.The organic silicon sealant is composed of a component A and a component B. The component A is prepared from a basic polymer, modified filler, functional filler and a plasticizer, and the component B is prepared from a dispersing agent, filler, a cross-linking agent, a catalyst and carbon black, the modified filler is a metal oxide modified by a silane coupling agent. The two-component condensed type organic silicon sealant is high in storage stability and small in performance fluctuation, the problems of uneven mixing and unbalanced mixing proportion and design proportion of a sizing material are avoided, and the prepared sizing material is low in viscosity, high in extrudability, high in vulcanization speed and more suitable for an automatic gluing process; the adhesive can be widely applied to sealing, bonding and protection in the fields of automobiles, electronic appliances, new energy, photovol
