Problems solved by technology

At present, HDPE ordinary mask self-adhesive waterproof membrane is commonly used, which has many advantages of underground waterproofing, and has incomparable deformation resistance and self-healing properties compared with self-adhesive membranes of polyester tire or glass fiber tire, but its resistance Water permeability, tensile strength, and weather resistance are poor. In recent years, the use of roofing or underground waterproofing projects in my country has been restricted.
In addition, the HDPE polymer waterproof sheet in the prior art has strict construction requirements, and the hot air method or welding method must be used for construction, which wastes financial and material resources, increases costs, and requires the ground to be dry, delaying the construction period

Abstract

The invention discloses a reaction-type high-strength laminated film waterproof roll which comprises a layer of high-strength cross laminated film (HDPE, high-density polyethylene) with thickness of 0.10-0.14mm and a layer of modified asphalt super glue which can react with cast-in-place concrete and is solidified together with the cast-in-place concrete. The waterproof roll can be chemically cross-linked and physically blended with concrete; under the effect of a coagent, a bonding layer can be continuously and permanently bonded with a base layer processing agent or the concrete poured on the bonding layer so as to completely prevent water from permeating into a clearance between the waterproof roll and the structure and form a skin-type net-shaped integer together with the base surface. Since the high-strength cross laminated film of special material HDPE has good tensile strength, breaking elongation rate and anti-puncture capability, the self-adhered waterproof roll of the high-strength cross film has the advantages of relatively good tensile strength, breaking elongation rate, anti-puncture capability and aging resistance.

Description

technical field [0001] The invention relates to a multi-layer composite waterproof material with superior performance, which belongs to the technical field of building waterproof materials, in particular to a reactive high-strength cross-laminated membrane modified asphalt waterproof roll capable of chemically reacting with cast-in-place concrete and curing together material. Background technique [0002] At present, self-adhesive waterproof membrane is a kind of self-adhesive rubber asphalt prepared with synthetic rubber such as SBS, tackifier and high-quality road petroleum asphalt as the base material, and tough high-density polyethylene film or aluminum foil as the upper surface material. , The peelable silicon-coated release film or silicon-coated release paper is a waterproof material made of anti-sticking release material on the lower surface. It is a new type of waterproof material with great development prospects. It has the characteristics of low temperature flexi...
