Embodiment 1

[0019] The "PBC-328" non-curing rubber bitumen waterproof coating produced by Oriental Yuhong and the SAM self-adhesive polymer modified bitumen waterproof membrane of Oriental Yuhong are used for compounding. That is, by heating the "PBC-328" non-curing rubber asphalt waterproof coating and brushing the hot coating on the base surface, and then paving the SAM self-adhesive polymer modified asphalt membrane on the surface.

Embodiment 2

[0021] Using popular "FBC-402" non-curing rubber asphalt waterproof coating and Oriental Yuhong's SBS (APP) polymer modified asphalt waterproofing membrane, that is, by heating "PBC-328" non-curing rubber asphalt waterproof coating and heat the coating Brush on the base surface, and then spread the SBS (APP) polymer modified asphalt waterproof membrane on the surface.

[0022] According to the construction method disclosed by the present invention, the above-mentioned embodiment is applied to the roof of the house, and the outside of the vertical wall and the bottom plate of the underground project are used as the waterproof layer. Inspections were carried out 1, 3, and 6 months after the construction, and it was found that the strength of the composite waterproof layer was good, in compliance with the construction regulations, and there was no water leakage, and no sandwich biscuit-like water channeling layer appeared.

Abstract

The invention discloses a non-cured rubber asphalt paint composite waterproof layer. The composite waterproof layer is formed by bonding non-cured rubber asphalt paint and a waterproof coil which is dissolved with the non-cured rubber asphalt paint. The composite waterproof layer gives full play to respective technological advantages of the non-cured rubber asphalt paint and the waterproof coil and a full-interface closed seal structure is formed by bonding the non-cured rubber asphalt paint and the waterproof coil firmly, thus achieving the aims of repairing and sealing cracks of subbases and capillary interstices and effectively preventing water channelling and water leakage between the composite waterproof layer and subbases.

Description

technical field [0001] The invention relates to a composite waterproof layer and belongs to the field of chemical materials for building waterproofing. Background technique [0002] In the current waterproof project, single-channel waterproof membrane, double-layer waterproof membrane, and single-channel waterproof coating are mostly used as the waterproof layer. The waterproof membrane and the base surface are bonded in two ways: hot-melt method and cold-lay method. In the current roofing and underground waterproofing works, there are relatively clear regulations on the above-mentioned waterproofing materials, building waterproofing structures, construction methods, and project acceptance. [0003] Although the membrane waterproof layer has high tensile strength, it has the defect of small elongation; the coating waterproof layer has high elongation, but has the defect of low tensile strength. The construction of the membrane waterproof layer adopts the hot-melt method. D...
