Description

Roof waterproof roll

Technical Field

The utility model relates to the field of building materials, in particular to a roof waterproof coiled material.

Background

After the 70 s of the 20 th century, the application of thin metal plates on roofs was promoted with the gradual development and mature application of cold roll forming technology. Metal roofing has entered the high-speed development stage, but in the process of using metal roofing in a large number, it is a great disadvantage of metal roofing to find easy corrosion. In order to solve this problem, the metal alloy sheet is produced as it is, and the corrosion becomes slow but continues. Later, people paint the metal plate and have certain effect on corrosion retarding. However, metal roofing systems often suffer from outer layer rust, roof water leakage, poor thermal insulation and heat preservation after 5-8 years of service, especially in coastal high humidity and high salt spray corrosion. Currently, solutions to this problem are metal roofing sheet replacement and roofing repair. The replacement of the metal roof plate has the problems of higher manufacturing cost, long construction period, material waste, shutdown requirement and the like. For roofing repair, roofing repair products on the market today include waterproofing rolls and coating products, but these products often do not meet the insulation requirements and the like. Therefore, a product having good water resistance and thermal insulation is urgently needed.
