Self-leveling insulation damp-resistance blocking agent

The invention relates to a self-leveling insulation damp-resistance blocking agent. The blocking agent comprises a component A and a component B. The weight ratio of the component A to the component Bis (8-10):1. The component A is prepared from, by weight, 20-40 parts of modified polysiloxane, 10-20 parts of a plasticizer, 3-10 parts of silicon dioxide, 10-60 parts of a flame retardant and 0.5-2parts of color paste. The component B is prepared from, by weight, 50-80 parts of a diluent, 5-10 parts of a catalyst, 10-20 parts of a cross-linking agent and 5-10 parts of a coupling agent. The self-leveling insulation damp-resistance blocking agent is low in viscosity and has good fluidity and a good levelling property, after the mixed materials are solidified at the room temperature, the self-leveling insulation damp-resistance blocking agent has excellent flame resistance, electric performance and bonding strength and has the advantages of resisting damp and shock, and the demand of actual application can be well
