Problems solved by technology

[0006] Traditional roof insulation methods often fail to achieve the designed heat insulation effect. The important reason is that traditional heat insulation materials have strong moisture absorption and water absorption, and the system itself is only composed of interface layer, heat insulation layer and anti-crack layer, without additional flexibility. The anti-cracking layer is often cracked due to factors such as construction, and moisture can easily penetrate into the insulation layer, especially on rainy days, the roof with a little water accumulation often loses the thermal conductivity of the insulation layer due to the increase in water absorption. Thermal insulation performance

Embodiment 1

[0053] (1) Clean the base surface so that the base surface is free of oil, loose matter, etc., and wet the base until saturated but without clear water;

[0054] (2) Apply cement-based permeable crystalline waterproof paint on the damp base surface treated in step (1), and apply two layers evenly, that is, the base surface waterproof layer;

[0055] This embodiment is a rigid waterproof coating made of Portland cement and refined quartz sand as the base material, mixed with active mineral powder. It is prepared by simply mixing active mineral micropowder. The weight of described Portland cement or ordinary Portland cement and refined quartz sand is 1:3;

[0056] In this embodiment, the average particle size of ultrafine mineral powder is less than 5 μm, and the specific surface area is 2.0-4.5 m 2 / g. The doping amount of the superfine mineral micropowder is 2.5% of the weight of the base material.

[0057] (3) After the base surface waterproof layer in step (2) is dry and...

Embodiment 2

[0087] Implementation steps are the same as in Example 1.

[0088] as attached figure 1 As shown, the roof system is mainly composed of base layer 1, base surface waterproof layer 2, expanded vitrified microbead insulation layer 3, anti-crack protection layer 4, flexible waterproof layer 7, leveling layer 7 and finish layer 8. First of all, make sure that the base is firm and flat, without hollowing, and the base surface should be cleaned without oil, mold release agent, floating ash, loose matter and other stains; defects on the base surface should be repaired in advance, and protrusions should be knocked out; Make oblique or arc angle. Before construction, wet the substrate to saturation but without clear water. Use a brush or roller to evenly apply the cement-based permeable crystalline waterproof slurry to the treated substrate. Keeping the substrate moist can help the slurry penetrate into the substrate. Generally, two coats need to be applied evenly. After the firs...

The system of the present invention can prevent cracks and water leakage on the concrete slab surface, improve the heat insulation effect of the building roof, and has good wind pressure resistance, excellent fire resistance, good surface smoothness and construction quality; the system is applicable to various Waterproof and heat insulation of climate and various building roof structures.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a roof heat insulation and waterproof composite system and a construction process. Background technique [0002] With the acceleration of my country's urbanization process and the advancement of the construction of "new socialist countryside", the development of the construction industry is in its heyday, and the annual construction area is about 2 billion square meters 2 , and building energy consumption continues to increase. At present, my country's housing construction area reaches 40 billion m 2 , it is estimated that by 2020, nearly 30 billion m 2 , exceeding the sum of the construction volumes of all developed countries. Among these new buildings, only 10-15% can meet the energy-saving standards set by the state, and more than 80% are high-energy-consuming buildings with relatively backward energy-saving technologies. [0003] The proportion of b...
