The invention discloses a staged delayed coagulation and viscosity reduction type iron aluminate cement water reducing agent and a preparation method thereof. The iron aluminate cement water reducing agent is obtained by copolymerizing prepared isopentenol polyoxyethylene ether borate, hydroxyethyl methylacrylate glucolactone and methacrylic acid.
