Abstract
The invention belongs to the technical field of building waterproof materials, and particularly relates to a high-viscosity modified asphalt waterproof coiled material and a preparation method thereof. The product developed by the invention comprises an asphalt layer, a polyester tire base layer and a PE film; the asphalt layer is coated on the surface of the polyester tire base layer; the PE film is covered on the surface of the asphalt layer; the asphalt layer includes: pitch and layered silicates; polymer microspheres are embedded between the layers of the layered silicate; the metal ions in the interlayer framework of the phyllosilicate are at least partially replaced by hydrogen ions. In addition, the asphalt also comprises thermoplastic elastomer with 5-10% of asphalt mass; wherein the polymer microsphere is obtained by emulsion polymerization of the following monomers: methacrylic acid, methyl methacrylate, butyl methacrylate and styrene. The product obtained by the invention is easy to be well wetted and spread on the surface of a concrete base material under the action of external force and heat during construction, and can keep high viscosity and waterproof effect after being cooled and solidified.
Description
Technical Field
The invention belongs to the technical field of building waterproof materials. More particularly, relates to a high-viscosity modified asphalt waterproof coiled material and a preparation method thereof.
Background
The waterproof coiled material is mainly used for building walls, roofs, tunnels, highways, refuse landfills and the like, can be curled into a roll-shaped flexible building material product for resisting external rainwater and underground water leakage, is used as a leakage-free connection between an engineering foundation and a building, is a waterproof first barrier of the whole engineering, and plays a vital role in the whole engineering. According to different main composition materials, the waterproof material is divided into an asphalt waterproof coiled material, a high polymer modified asphalt waterproof coiled material and a synthetic polymer waterproof coiled material; the coiled materials are divided into coiled materials without a matrix, coiled materials with a paper matrix, coiled materials with a glass fiber matrix, coiled materials with a glass cloth matrix and coiled materials with a polyethylene matrix according to different matrixes.
The waterproof roll is required to have good water resistance, stability to temperature change (no flow, no bubble, no disturbance and no brittle fracture at high temperature), certain mechanical strength, extensibility and fracture resistance, certain flexibility and aging resistance and the like.
The polymer self-adhesive waterproof coiled material (with the self-adhesive layer) has the characteristics of the polymer waterproof coiled material (such as high tensile strength, high elongation at break, high tearing strength, long service life and the like), and also has the advantages of self-adhesiveness, self-healing property, creep property, convenience and rapidness in construction operation, safety, environmental protection, no environmental pollution and the like which are unique to the self-adhesive waterproof coiled material. Therefore, the waterproof coiled material has better waterproof efficiency and is widely applied to the fields of buildings, traffic waterproofing and the like. At present, most self-adhesive layers of macromolecular self-adhesive waterproof coiled materials in the market are modified asphalt self-adhesive layers, and the self-adhesive layers mainly depend on physical adsorption (reversible adhesion) in the aspect of adhering the coiled materials and a concrete base surface, so that the self-adhesive layers are not firm enough; meanwhile, the weather resistance and the durability of the asphalt are poor, so that the coiled material and a concrete base surface are easy to be bonded and lose efficacy, and water channeling, water leakage and the like are caused.
In addition, in order to improve the shape stability of the asphalt waterproof coiled material, a high-viscosity system is often needed, however, the high-viscosity asphalt cannot ensure good wetting and spreading of the concrete substrate in the construction process, and therefore, how to consider the waterproof stability of the product and the convenience of construction is one of the technical problems to be solved urgently by the technical staff in the field.
Disclosure of Invention
The invention aims to overcome the defects that the existing asphalt-based waterproof coiled material cannot give consideration to both the waterproof stability of the product and the construction convenience, and provides a high-viscosity modified asphalt waterproof coiled material and a preparation method thereof.
The invention aims to provide a high-viscosity modified asphalt waterproof coiled material.
The invention also aims to provide a preparation method of the high-viscosity modified asphalt waterproof coiled material.
The above purpose of the invention is realized by the following technical scheme:
a high viscosity modified asphalt waterproofing membrane, includes: the asphalt layer, the polyester base layer and the PE film;
