Description

Technical Field

[0001] The invention relates to the technical field of repairing factory metal roofs, and in particular to waterproof color tiles for factory metal roofs and a method for repairing factory metal roofs. Background Art

[0002] With the development of industrialization, factories are now mainly built with metal roofs, but the metal roofs of factories are mainly made of metal plates such as steel plates and copper plates. These plates are prone to rust after long-term use, and will experience corrosion, leaks and other phenomena.

[0003] At present, waterproof coatings, waterproof tapes or waterproof coils are mainly used for the maintenance of factory metal roofs. For example, the Chinese invention patent with application number 201410218031.4 discloses a self-standing waterproof tape for quickly repairing the roof waterproof layer. This waterproofing requires manual climbing to the roof for pasting, which is dangerous. If the roof is repaired on a large area, the operation is very cumbersome. In order to meet the needs of environmental protection, waterproof coatings are mainly water-based waterproof coatings. Water-based waterproof coatings need to be constructed on sunny days. If they are constructed on rainy days, the water-based waterproof coatings cannot dry thoroughly and are easily washed away by rain. For southern my country or rainy areas, it is necessary to wait until sunny days for the maintenance of factory roofs, which seriously affects the construction progress. Waterproof coils also need to be manually laid, especially for toothed factory metal roofs, which are difficult to construct and have high labor costs.

[0004] Therefore, in order to solve the above problems, the applicant proposes a waterproof color tile that can be constructed on rainy days, has good waterproof performance, and has a simple construction method, which is used for the repair and maintenance of the metal roof of the factory. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a waterproof color tile for a metal roof of a factory building. The waterproof color tile is used for the repair and maintenance of the metal roof of a factory building, can be constructed on rainy days, has good waterproof performance and a simple construction method.
