Waterproof system for metal roof

Abstract

The invention provides a waterproof system for a metal roof. A water-based coating which contains following components by weight percent: 45-55% of cyano ethyl acrylate, 5-15% of functional assistant penetrating agent, 40-50% of aluminum oxide and silicon nitride, is adhered to a substrate layer; a reinforced polyester cloth is used as the substrate layer, thereby promoting the tensile strength of a waterproof layer; and then a substrate layer waterproof slurry, a waterproof layer closed slurry and a heat-insulating surface coating are sequentially arranged on the substrate layer; the substrate layer waterproof slurry passes through the netted gaps of the polyester cloth, thereby integrating the upper and lower layers of coatings with each other; the waterproof layer closed slurry can ensure tight closing of the waterproof layer; and the heat-insulating surface coating is used for reflecting light irradiation, resisting ultraviolet irradiation and ageing, and prolonging the service life of the waterproof system. The waterproof system is used for solving the problem in directly preparing a waterproof layer without preparing a protecting layer on the metal roof and the waterproof system has the advantages of ultrahigh tensile strength and ultraviolet resistance. The service life of the waterproof system is as long as 25 years, thereby prolonging the service life by 1.5-4 times.

Description

technical field [0001] The invention relates to a waterproof system, especially a metal roof waterproof system. Background technique [0002] At present, most of the waterproof materials such as traditional waterproof membranes, silicone weather-resistant adhesives, polyurethane coatings, and other polymer waterproof coatings must be provided with a protective layer on the waterproof layer in the application of concrete waterproofing. Traditional waterproof materials such as: polyurethane waterproof coating reference standard GB-T19250-2003; JS waterproof coating reference standard JCT984-2005; coil material reference standard GB18967-2009 have no requirements for UV resistance; The ability is not very good, and the weather resistance is not very ideal. If the above materials are directly used for waterproofing on outdoor metal roofs, there will be a problem of short waterproof durability, and water seepage will occur soon. The reason for this kind of problem is that the m...

Problems solved by technology

If the above materials are directly used for waterproofing on outdoor metal roofs, there will be a problem of short waterproof durability, and water seepage will occur soon

The reason for this kind of problem is that the material itself has very poor anti-ultraviolet ability, and the second is that the waterproof system is unreasonable.

There are other rigid waterproof materials such as permeable crystalline waterproof coatings, K11 general-purpose waterproof coatings and waterproof slurry. Due to poor deformation resistance, the scope of use has its limitations.

[0003] In addition, traditional outdoor metal roof waterproofing generally requires a protective layer. Once a problem occurs, it is difficult to find the cause and repair; at the same time, the protective layer also consumes materials and manpower, wastes resources, and is not conducive to energy saving.
