The invention discloses a technical method of preparing elastic coating for a resin-based composite material from waste PET. The method includes the steps of: with the waste PET as raw material, performing PET degradation, blending of a degradation product BHET and the like steps to produce the coating. The coating is easy to use and cure, a coating layer formed after the coating is cured has goodelasticity and corrosion resistance, and is high in adhesion force on the resin resin-based composite material. With the waste PET as a main raw material, the technical method is low in cost and energy consumption and is simple in process. The coating can be used for coating various high-filled resin-based composite materials and satisfies the fundamental policy of promoting cyclic economy development and protecting ecologic environment in our country. The coating is high in adhesion force and elasticity, is easy to colorize, is good in corrosion resistance and heat resistance, and has greatmarket promotion and appli
