Problems solved by technology

The upper and lower rubber edge films of the patented coil are used as wet-laid coils, and the coils are bonded to the cushion during construction. At the same time, the construction personnel remove the isolation film on the upper surface of the coil. Walking sticky feet on the coil, poor construction convenience

Embodiment Construction

[0034] The present invention is further described below in conjunction with specific examples. The raw materials and equipment used in the following examples are commercially available unless otherwise specified.

[0035] A self-adhesive waterproof membrane material with super-strength cross-laminated film, which includes, from top to bottom, an isolation protective layer 2, a non-bitumen-based self-adhesive layer 3, a strong cross-laminated film 4, an asphalt self-adhesive layer 5 and PE isolation The film 6 has overlapping edges 1 and 7 on one side of the coil, and the material of the overlapping edges is PET isolation edge film.

[0036] Among the above materials, the isolation protection layer is a sand layer (the particle size of the sand is 30-40 mesh, 30-45%, 40-60 mesh 30-50%, and the balance is 60-70 mesh), and the non-bitumen-based self-adhesive layer is hot-melt Adhesive layer (thickness 0.3-0.5mm), asphalt self-adhesive layer (thickness 1.0-1.2mm), PE isolation fi...

Abstract

The invention relates to a self-adhesive waterproof coiled material of a super-strength cross-lamination film, which comprises an isolation protective layer, a non-asphalt-based self-adhesive layer, a strong cross-lamination film, an asphalt self-adhesive layer and a PE isolation film from top to bottom. There is an overlapping edge on one side of the upper surface of the coiled material, and an overlapping edge is also left on the other side of the lower surface of the coiled material. The waterproof membrane provided by the present invention has better bonding performance with the post-cast concrete than the asphalt-based membrane, and can be better bonded with the main structure (that is, the pre-laid anti-adhesive membrane). The strong cross-laminated membrane in the middle of the membrane has Good ductility, when the base layer subsides or the main structure is slightly deformed, the coil can continue to maintain good adhesion to the main structure without detachment, and it will also have a good waterproof effect.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a self-adhesive waterproof roll material of a super-strength cross-laminated film and a preparation process. Background technique [0002] Strong cross-laminated self-adhesive waterproofing membrane is a high-performance, cold-applied tireless waterproofing membrane based on hot-melt adhesive, thermoplastic elastomer, high-quality asphalt, tackifier and anti-aging agent. During the construction process, the waterproof membrane is directly laid on the base layer after the isolation film is removed. After the waterproof membrane is laid, steel bars are bound on the upper surface (sand surface) of the membrane and concrete is cast to realize the waterproof function. Most of the self-adhesive waterproof rolls of strong cross-laminated membranes in the prior art use asphalt-based self-adhesive adhesives coated on one or both sides of the strong cross-laminated membranes. The above-...
