The invention relates to the technical field of environment-friendly materials, and discloses a corrosion and scale inhibitor as well as a preparation method and application thereof. The corrosion and scale inhibitor is prepared from the following components in parts by mass: 140 to 160 parts of a polyaspartic acid derivative, 95 to 105 parts of quaternary ammonium salt, 25 to 35 parts of sodium molybdate, 45 to 55 parts of thiourea, 3 to 7 parts of potassium iodide and 600 to 700 parts of a solvent. According to the corrosion and scale inhibitor provided by the invention, the polyaspartic acid derivative and the quaternary ammonium salt are used as main components, sodium molybdate and the like are used as synergistic aids, and the corrosion and scale inhibitor is a novel phosphorus-free, environment-friendly and excellent-performance corrosion and scale inhibitor. The preparation method of the corrosion and scale inhibitor is simple, the acetone can be recycled, the environmental protection requirement is m
