Adhesive tape matched with polymeric prelaid waterproofing membrane, and construction application thereof

Abstract

The invention discloses an adhesive tape matched with a polymeric prelaid waterproofing membrane. The adhesive tape matched with the polymeric prelaid waterproofing membrane comprises a PE release film, a polymeric self-adhesive film, a strong cross Laminated PE composite film, a polymeric self-adhesive film and a special surface particle layer which are sequentially arranged from bottom to top. The invention also provides a construction application of the adhesive tape matched with the polymeric prelaid waterproofing membrane. The adhesive tape matched with the polymeric prelaid waterproofingmembrane has the characteristics of good bonding property, high strength, softness, lightness and thinness, so the adhesive tape can be used to solve many problems occurring in onsite construction ofthe polymeric prelaid waterproofing membrane.

Description

technical field [0001] The invention relates to an adhesive tape for matching polymer pre-laid waterproof coiled material and its construction application. Background technique [0002] The polymer pre-laid waterproof membrane is formed by coating the polymer self-adhesive on the surface of the polymer sheet main body (HDPE, TPO, etc.), and finally spreading the particle layer on the adhesive layer; It has good tensile strength and elongation at break, and excellent physical properties, so there is no need to construct a protective layer during construction, which greatly reduces the construction period and cost; and the coiled material layer can be fully adhered to the post-cast concrete floor without water leakage, which is the current The most economical and reliable solution for basement floor waterproofing. [0003] However, through a large number of engineering examples, there are still the following problems in the on-site construction of polymer pre-laid waterproof ...

AI Technical Summary

Problems solved by technology

[0004] 1. The polymer pre-laid waterproof membrane is self-adhesively lapped through the polymer adhesive layer. Due to the obvious thermal expansion and contraction characteristics of the plastic during construction in summer, the lapped edge of the membrane may have a problem of disengagement, which will affect the waterproofing Effect

[0005] 2. The on-site construction of polymer pre-laid waterproof membranes generally does not require a protective layer. Once the waterproof layer is damaged, it is very difficult to repair

[0006] 3. The polymer pre-paved waterproof membrane is hard, and it is difficult to seal and handle the joints, such as the yin and yang corners.

[0007] 4. Polymer pre-laid waterproof membranes are generally used in tunnels with hot-melt welding lap joints. The coils at the lap joints have only the main body of the sheet, which cannot be bonded with post-poured concrete, which affects the waterproof quality.
