High polymer self-adhesive glue film waterproof roll adopting pre-laid stick side up construction method and production method of roll

Abstract

The invention discloses a high polymer self-adhesive glue film waterproof roll adopting a pre-laid stick side up construction method and a production method of the roll. The high polymer self-adhesive glue film waterproof roll comprises a main high polymer waterproof layer, a self-adhesive glue layer, an anti-sticking layer and a PET film overlapped edge layer, the high polymer self-adhesive glue film waterproof roll has the service life of 70 years above, and has the tensile strength of 750N / 50mm above; the nail rod tear resistance is 500N above, the peel strength between the roll and post-pouring concrete is 2.5N / 50mm, and the peel strength between rolls is 2.5N / 50mm. According to the waterproof roll disclosed by the invention, the self-adhesive glue layer and the post-pouring concrete can be subjected to a chemical reaction to be cured to form an integrated body, so that full adhesion between the main waterproof layer and the structural concrete can be realized, and the problem of seepage and channeling of underground water or failure of the main waterproof layer caused by foundation settlement can be effectively solved.

Description

technical field [0001] The invention relates to a waterproof coiled material for construction, more specifically to a polymer self-adhesive waterproof coiled material with pre-paved anti-adhesive construction and a production method thereof, belonging to the field of building waterproof materials. Background technique [0002] In the underground waterproofing project, the traditional waterproofing membrane has no construction space on the floor and side walls, so the technical route of external defense and internal sticking can only be adopted. The waterproofing membrane is only bonded to the base layer and not to the structural concrete itself; but Existing waterproof membranes often focus on the waterproof effect, which leads to low strength of other physical properties such as tensile properties and tear properties. Once damaged, groundwater is prone to channeling between the structural concrete and waterproof membrane layers, thereby Cracks in the structural concrete flo...

Problems solved by technology

[0002] In the underground waterproofing project, the traditional waterproofing membrane has no construction space on the floor and side walls, so the technical route of external defense and internal sticking can only be adopted. The waterproofing membrane is only bonded to the base layer and not to the structural concrete itself; but Existing waterproof membranes often focus on the waterproof effect, which leads to low strength of other physical properties such as tensile properties and tear properties. Once damaged, groundwater is prone to channeling between the structural concrete and waterproof membrane layers, thereby The cracks in the structural concrete flow into the building, and although some waterproof membranes have good waterproof and physical properties, they have poor weather resistance and short service life, which will also cause great hidden dangers

[0003] At the same time, because the waterproof membrane is bonded to the base layer, once the foundation subsides, the base layer is prone to deformation and settlement. exposure to groundwater
