Embodiment 1

[0077] Wherein, the above-mentioned PVC waterproof coiled material 5 is obtained by extrusion molding process by 900g polyvinyl chloride resin, 50g compatibilizer-maleic anhydride grafted polystyrene and 125g biocidal herbicide-propazone (extrusion molding specific process Parameters: equipment - twin-screw extruder, metering section: 100-130°C, compression section: 120-140°C; conveying section: 135-145°C, screw speed: 400r / min).

Embodiment 2-3

[0079] The difference from Example 1 is that the weights of raw materials in Examples 2-3 are different, as shown in Table 2.

[0080] Each raw material composition and its weight table (g) in the embodiment 1-3 of table 2

[0081]

Embodiment 4

[0083] The difference from Example 1 is that proturazin is replaced by acetochlor in mutual weight.

Abstract

The invention relates to the technical field of roof waterproof engineering, in particular to a waterproof structure of a building roof and a construction method thereof. The waterproof structure of the building roof comprises a structural layer, a cement mortar slope making layer, an adhesive layer and a PVC waterproof coiled material layer which are sequentially arranged upwards, and the PVC waterproof coiled material layer comprises a plurality of PVC waterproof coiled materials which are sequentially overlapped. The construction method of the waterproof structure of the building roof comprises the steps: S1, base layer treatment; S2, coiled material pavement; and S3, after-treatment of the coiled material. The structure has an effect of improving the waterproof performance of the roof.

Description

technical field [0001] The present application relates to the technical field of roof waterproofing engineering, in particular to a building roof waterproof structure and a construction method thereof. Background technique [0002] With the development of my country's construction technology in recent years, large-span, light and high-rise buildings are increasing, and the deformation of roof structures has also undergone major changes. Among them, the emergence of new situations such as roof parking lot, roof sports field and roof garden have greatly increased the function of the roof, but at the same time, the problem of house leakage has also become a very prominent problem in my country's engineering construction. [0003] In the related art, in order to improve the waterproof performance of the roof, the staff usually glue and lay PVC waterproof coiled material on the surface of the roof, and because the PVC waterproof coiled material has excellent water resistance, sta...
