Reactive composite waterproof sealant containing methylacryloyloxy bridging agent and preparation method for reactive composite waterproof sealant

The present invention aims to provide reactive composite waterproof sealant containing a methylacryloyloxy bridging agent and a preparation method for the reactive composite waterproof sealant The waterproof sealant comprises synthetic rubber latex, emulsified asphalt, and a bridging agent. The bridging agent is added into a formula system of the present invention; the bridging agent, asphalt and rubber in the waterproof sealant can form chemical cross-linking and physical tenon synergetic cohesive action with uncured cement or concrete for tightly connecting the sealant and the cement into an integer; chemical bond actions exist in relevant parts and make reversible bonding effects after curing. In a cement curing process, the waterproof sealant can permeate into pores of cement gel and the concrete, thereby achieving tight and firm fastening and reversible bonding effects as flesh and blood.
