Roof repairing waterproof heat preservation structure

The utility model aims to provide a roof repairing waterproof thermal insulation structure, which is characterized by comprising a waterproof layer, a first bonding layer, a thermal insulation layer, a second bonding layer and a filling layer, integrally adopting a lap joint structure design, and has the advantages of good bonding performance and excellent aging resistance, thereby prolonging the service life and improving the waterproof thermal insulation performance. The roof waterproof structure prevents waterproof failure caused by cracking and aging of the roof waterproof structure due to solarization and raining, the overall structure is noise-reducing, heat-insulating and high in elongation rate, has a sound-insulating function, is more energy-saving and environment-friendly, improves the overall bonding strength, is firmer, effectively avoids flowing and sliding of a self-adhesive layer of the waterproof structure due to high surface temperature of the color steel roof, and is more durable. And thus,
