Problems solved by technology

[0003] In view of the above-mentioned related technologies, the inventor believes that in the practical application of color steel plate renovation, the topcoat is directly sprayed on the polished and cleaned color steel plate surface to form a waterproof layer, and the waterproof layer has poor adhesion on the color steel plate surface. At the same time, under the influence of seasonal changes and temperature differences between day and night, the color steel plate will expand with heat and contract with cold, especially in the northeast and other places, the temperature on the surface of the color steel plate can rise to 60°C in summer, or even as high as 70°C. In winter, the temperature on the surface of the color steel plate can be reduced to -30°C, or even as low as -40°C, and the waterproof layer is easy to detach and crack due to the thermal expansion and contraction of the color steel plate.

Description

technical field [0001] The present application relates to the technical field of water-based glue, more specifically, it relates to a weather-resistant water-based waterproof composite glue and its preparation method and application. Background technique [0002] Color steel plate is a commonly used steel structure in industrial plants. There is a waterproof layer on the surface of color steel plate, which can play a waterproof effect. However, since the color steel plate is exposed to the outdoors and the color steel plate is used for a long time, the waterproof layer will inevitably Falling off will affect the use of color steel plate. At this time, it is necessary to renovate the color steel plate. In the renovation of the color steel plate, the waterproof layer on the surface of the color steel plate is generally removed first, then the surface of the color steel plate is polished and cleaned to remove the rust on the surface, and then the surface of the color steel plat...
