Description
Technical Field
The invention belongs to the technical field of waterproof materials. More particularly, relates to an environment-friendly high-temperature-resistant 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.
However, in the use scene of the waterproof asphalt coiled material, the asphalt coiled material is required to have higher high-temperature thermal stability in a part of areas, namely, the product is required to still maintain good mechanical properties under a high-temperature condition, and the base layer is covered to avoid waterproof failure under the high-temperature condition.
Disclosure of Invention
The invention aims to solve the technical problems that the existing asphalt waterproof coiled material has insufficient high-temperature resistance and is easy to cause waterproof failure in a long-term high-temperature environment, and provides an environment-friendly high-temperature-resistant asphalt waterproof coiled material and a preparation method thereof.
The invention aims to provide an environment-friendly high-temperature-resistant asphalt waterproof coiled material.
The invention also aims to provide a preparation method of the environment-friendly high-temperature-resistant asphalt waterproof coiled material.
The above purpose of the invention is realized by the following technical scheme:
an environment-friendly high-temperature resistant asphalt waterproof coiled material comprises an emulsified asphalt layer, a polyester tire base layer and a PE film;
the emulsified asphalt layer is coated on the surface of the polyester tire base layer;
the PE film is covered on the surface of the emulsified asphalt layer;
the emulsified asphalt layer comprises composite asphalt particles with the particle size of less than 500 mu m;
the composite asphalt particles are compounded by graphene oxide, petroleum asphalt and anionic polyacrylamide.
In the technical scheme, the graphene oxide is introduced into the petroleum asphalt system, has a large specific surface area, and can adsorb light components in the petroleum asphalt, such as oil content, saturated components and the like, so that the volatilization of the oil content and the saturated components of the product under a high-temperature condition is effectively avoided, and the high-temperature resistance and stability of the product are improved;
in addition, according to the technical scheme, the emulsified asphalt layer is formed on the surface of the polyester tire base layer by utilizing the composite asphalt particles with the particle size of less than 500 microns, on one hand, after coating is completed, the particles are sparse and discontinuous in the early drying stage, the solvent among the particles disappears along with the continuous volatilization of the solvent, and the particles are densely stacked to form a continuous coating structure; on the other hand, because of the accumulation among the particles, when the product is subjected to a high-temperature condition, because the accumulated gaps exist among the particles, the asphalt particles can expand to a certain degree by utilizing the accumulated gaps among the original particles under the high-temperature environment, and the original gaps are filled, so that the water resistance of the product is not reduced and is not increased;
moreover, according to the technical scheme, the anion polyacrylamide is used as an auxiliary material in the system, the resin has certain water absorption performance, and can absorb water quickly after meeting water when the product does not meet high temperature, and water molecules are transferred to the interior of molecular structures of asphalt and graphene oxide, so that the volume expansion of asphalt particles is caused, the original water diffusion channel can be blocked quickly after expansion, and a good water stopping effect is achieved.
Further, the emulsified asphalt layer comprises the following composite asphalt particles with different particle size distributions in parts by weight: 10-30 parts of composite asphalt particles with the particle size distribution range of 400-500 mu m, 20-40 parts of composite asphalt particles with the particle size distribution range of 100-200 mu m and 30-50 parts of composite asphalt particles with the particle size distribution range of 1-50 mu m.
Above-mentioned technical scheme is through using the compound pitch granule of different particle size distribution ranges as the raw materials, in the actual product use, under the same high temperature, the not inflation of equidimension can take place for the granule of different particle sizes to balanced whole coiled material's stability avoids the coiled material to expand in a large number in the twinkling of an eye and arouses bonding waterproof failure.
Further, a nano silicon dioxide layer is also arranged between the emulsified asphalt layer and the PE film;
the nano silicon dioxide layer is formed by compounding nano silicon dioxide modified by a coupling agent and PVDF.
Further, the nano silicon dioxide is monodisperse nano silicon dioxide, and the particle size distribution range of the monodisperse nano silicon dioxide is 5-10 nm.
Further, the coupling agent is any one of a silane coupling agent KH-550, a silane coupling agent KH-560 and a silane coupling agent KH-570.
Above-mentioned technical scheme further introduces the nanometer silica layer between emulsified asphalt layer and polyester child basic unit, because pile up between nanometer silica granule and the granule and have the clearance of piling up, when pitch takes place to melt under the higher temperature, the clearance between the nanometer silica granule can play good siphon effect, adsorb the pitch that gets into in its clearance with the melting, avoid pitch to run off and influence the waterproof performance of product, and because the cohesion of nanometer granule between the granule is great, even inside adsorbed pitch melts, still can play the effect of avoiding its loss, thereby prevent the waterproof inefficacy of product.
A preparation method of an environment-friendly high-temperature-resistant asphalt waterproof coiled material comprises the following specific preparation steps:
preparing composite asphalt particles:
