The invention discloses a manufacturing method for high-performance rubber-type chlorinated polyethylene with the water-phase method. The manufacturing method comprises the following steps of: softening hot water, dispersing agent, emulsifying agent and polyethylene powder are added in a proportioning tank in turn and are stirred to form suspension feed liquid, then completing discharging; the suspension feed liquid in the proportioning tank is fed in a chlorination reaction kettle, and then initiator is added; when the mixture is heated to 75 DEG C under a sealed condition, chlorine gas is pumped into the reaction kettle, thereby obtaining the mother liquor of rubber-type chlorinated polyethylene after 2 to 3 hour reaction under 75 to 140 DEG C and pressure less than or equal to 0.45MPa; and the mother liquor is fed to a rinsing kettle to be filtered and then is neutralized through a neutralization kettle, and is made into a high-performance rubber-type chlorinated polyethylene finished product after washing
