The invention discloses a cold-resistant polymer waterproof composite metal plate. The composite plate is sequentially bonded in the thickness direction from top to bottom: a first polymer waterproof coil layer, a glass fiber non-woven inner reinforcement layer, a second polymer waterproof coil layer, a non-woven fabric composite layer, a first adhesive layer and a metal plate layer. The metal plate layer is subject to thermal expansion and cold contraction, while the first and second polymer waterproof coil layers have a high thermal shrinkage coefficient. The glass fiber non-woven inner reinforcement layer with a low shrinkage coefficient is sandwiched between the two waterproof layers to control their dimensional change rate, preventing delamination and peeling from the metal plate layer under high temperature or sunlight exposure.
