[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0018] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same reference numerals represent the same or corresponding technical features. Each of the accompanying drawings is only a schematic diagram and is not necessarily drawn according to the actual scale.

[0019] See also Figure 1 and Figure 2 As shown in the figure, a roof waterproof structure with high weather resistance includes: a roof substrate 1, a waterproof coating bottom layer 2 is arranged on the top of the roof substrate 1, a cement mortar layer 3 is arranged on the top of the waterproof coating bottom layer 2, a waterproof coating middle layer 4 is arranged on the top of the cement mortar layer 3, a polyester tire aluminum film layer 5 is arranged on the top of the waterproof coating middle layer 4, a weather-resistant layer 6 is arranged on the top of the polyester tire aluminum film layer 5, the weather-resistant layer 6 includes a polyurethane layer 61, a polymer nano coating 62 is arranged on the outer surface of the polyurethane layer 61, and a waterproof sealing coating layer 63 is arranged on the outer surface of the polymer nano coating 62.

[0020] Furthermore, the cement mortar layer 3 is a rigid multi-layered cement mortar for plastering, and the cement mortar layer 3 is a cement paste prepared by adding cement and water and a cement mortar prepared by cement, sand and water.

[0021] In this embodiment, by setting the cement mortar layer 3, the cement slurry prepared by adding cement and water and the cement mortar prepared by cement, sand and water are layered and alternately spread and compacted so that most of the capillary channels in each layer are cut off, and the small amount of remaining capillary pores cannot form a through seepage hole network. The hardened waterproof layer has higher waterproof and anti-seepage properties, thereby increasing the waterproof effect of the roof substrate 1.

[0022] Furthermore, the top of the waterproof coating bottom layer 2 is adhered to the bottom of the cement mortar layer 3, and the top of the cement mortar layer 3 is adhered to the bottom of the waterproof coating middle layer 4.

[0023] In this embodiment, the waterproof coating bottom layer 2 and the waterproof coating middle layer 4 are provided to prevent water penetration and protect the building from moisture, mildew and other water-related damages. They achieve this function by forming a waterproof film with extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance after curing, thereby increasing the waterproof performance of the roof substrate 1.

[0024] Furthermore, the top of the waterproof coating middle layer 4 is adhered to the bottom of the polyester-based aluminum film layer 5 , and the bottom of the polyester-based aluminum film layer 5 is adhered to the bottom of the weather-resistant layer 6 .

[0025] In this embodiment, the polyester-based aluminum film layer 5 is cut, the roof is cleaned, and then the connection between the roof base and the waterproof membrane is continuously heated with a spray gun. When the heated position melts, the membrane can be rolled while heating. When the membrane is laid to the edge, it is necessary to seal the edge. The connection of the membrane is heated with a spray gun to make the connection firmly bonded, and the edge is sealed with a sealing paste to achieve seamless waterproofing. The roof substrate 1 can be waterproofed again through the polyester-based aluminum film layer 5. Through the setting of the weather-resistant layer 6, it has good ductility, cold and high temperature resistance, aging resistance, corrosion resistance, flame retardancy, is simple and convenient to use, and has good weather resistance.

[0026] Furthermore, the outer surface of the polyurethane layer 61 is adhered to the inner surface of the polymer nano coating 62 , and the outer surface of the polymer nano coating 62 is adhered to the inner surface of the waterproof sealing coating layer 63 .

[0027] In this embodiment, through the provision of the polyurethane layer 61, the polymer nano coating 62 and the waterproof sealing coating layer 63, the good weather resistance of the polyurethane layer 61 is crucial to the protection of the building, and can effectively prevent the damage of ultraviolet radiation to the building. Ultraviolet radiation is one of the main causes of aging of building materials. Long-term exposure to ultraviolet rays will cause the surface of the building to become brittle, discolored and cracked. In addition, the temperature change resistance can resist the influence of extreme climatic conditions. Whether it is a cold winter or a hot summer, the surface of the building will expand and contract due to temperature changes.

[0028] Furthermore, the waterproof coating bottom layer 2 and the waterproof coating middle layer 4 are made of the same material, and both the waterproof coating bottom layer 2 and the waterproof coating middle layer 4 are flexible waterproof coatings.

[0029] In this embodiment, the high-quality polyurethane layer 61 can maintain its flexibility and adhesion, effectively prevent the coating from cracking and peeling, increase the weather resistance of the roof substrate 1, and extend the service life of the waterproof structure of the roof substrate 1.

[0030] When in use, by setting the cement mortar layer 3, the cement slurry prepared by adding cement and water and the cement mortar prepared by cement, sand and water are alternately applied and compacted in layers, so that most of the capillary channels in each layer are cut off, and the remaining small amount of capillary pores cannot form a through water seepage hole network. The hardened waterproof layer has high waterproof and anti-seepage properties, which increases the waterproof effect of the roof substrate 1. The setting of the waterproof coating bottom layer 2 and the waterproof coating middle layer 4 mainly prevents moisture from penetrating and protects the building from moisture, mold and other water-related damages. They achieve this function by forming a waterproof film with elongation, elastic-plasticity, crack resistance, anti-seepage and weather resistance after curing, which increases the waterproof performance of the roof substrate 1. The polyester tire aluminum film layer 5 is cut, the roof is cleaned, and then the connection between the base layer of the roof and the waterproof roll is continuously heated with a spray gun. When the heating position melts, the roll can be rolled while heating. When the roll is laid to the edge, it is necessary to seal the edge and heat the roll connection with a spray gun to make the connection bonded. The roof substrate 1 is waterproof again through the polyester aluminum film layer 5. The weather-resistant layer 6 has good ductility, cold and high temperature resistance, aging resistance, corrosion resistance, flame retardancy, and is simple and convenient to use. In addition, it has good weather resistance. Through the arrangement of the polyurethane layer 61, the polymer nano coating 62 and the waterproof sealing coating layer 63, the good weather resistance of the polyurethane layer 61 is crucial to the protection of the building, and can effectively prevent the damage of ultraviolet radiation to the building. Ultraviolet radiation is one of the main causes of aging of building materials. Long-term exposure to ultraviolet rays will cause the surface of the building to become brittle, discolored and cracked. In addition, the temperature change resistance can resist the influence of extreme climatic conditions. Whether it is cold winter or hot summer, the surface of the building will expand and contract due to temperature changes. The high-quality polyurethane layer 61 can maintain its flexibility and adhesion, effectively prevent cracking and peeling of the coating, increase the weather resistance of the roof substrate 1, and extend the service life of the waterproof structure of the roof substrate 1.
