Embodiment Construction

[0040] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0041] The present invention provides a cross-laminated membrane pre-laid waterproof membrane, which includes sequentially stacked from top to bottom:

[0042] sand layer,

[0043] first modified asphalt adhesive layer,

[0044] Polymer strong cross lamination layer,

[0045] Second modified asphalt adhesive layer,

[0046] And PE isolation film layer;

[0047] One side of the waterproof membrane is also provided with an overlapping edge, and the sand layer at the overlapping edge is vacant.

[0048] The sand grain layer adopts artificial synthetic sand treated with carbonization and calcification.

[0049] The high-molecular strength cross-laminated film layer is formed ...

Abstract

The invention discloses a cross-layer pressed film pre-laying waterproof coiled material which comprises a sand grain layer, a first modified asphalt adhesive layer, a macromolecule strong cross pressed film layer, a second modified asphalt adhesive layer and a PE (polyethylene) isolation film layer. An overlap joint edge is arranged on one side of the waterproof coiled material, and the sand grain layer at the overlap joint edge is omitted. The cross-layer pressed film pre-laying waterproof coiled material is constructed by a pre-laying inverted adhesive process and can be closely adhered with post-cast concrete, a water channeling layer between a waterproof layer and a concrete structure is removed, the influence of ultraviolet rays and sediment pollution on adhesive property can be effectively resisted, bulking and wrinkling of the coiled material caused by change of day and night temperature differences can be avoided after the coiled material is constructed, laying is smooth, andthe overlap joint edge does not easily release. Compared with a traditional construction method, construction cost can be saved, a construction period can be shortened, and waterproof quality can be improved when the coiled material is used for waterproof construction of a pre-laying portion.

Description

technical field [0001] The present invention relates to a cross-laminated membrane pre-laid waterproofing membrane. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering basis The leak-free connection with the building is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. [0003] The existing waterproof membrane has the following defects: [0004] 1. The bonding performance of the adhesive layer is poor. After a short period of exposure to the sun, the bonding performance is lost, and the problem of asphalt-based coiled materials is particularly prominent. [0005] 2. The paving of materials is uneven, and there will be problems with empty paving. [0006] 3. The façade is not flexible to fix. The existing pr...
