Description

Technical Field

[0001] The invention relates to the technical field of waterproof coiled materials, and in particular to an interlocking overlapping double polymer membrane-based waterproof coiled material. Background Art

[0002] Waterproof membrane is a kind of waterproof material, which is often used in the waterproofing projects of buildings. Through its own impermeability, it forms a continuous waterproof layer on the surface of the building to prevent the penetration of water, thereby protecting the structure of the building from water erosion and providing reliable waterproof protection for various projects. The interlocking overlapping double polymer membrane-based waterproof membrane is a new type of waterproof membrane, which belongs to the polymer waterproof membrane. This waterproof membrane adopts a unique interlocking double overlap technology, so that there will be no water leakage at the overlap edge, reducing the leakage problem caused by the loose overlap edge. However, the traditional interlocking overlapping double polymer membrane-based waterproof membrane has defects in tensile properties, which affects its service life. Therefore, it is of great significance to develop an interlocking overlapping double polymer membrane-based waterproof membrane with good tensile properties. Summary of the invention

[0003] The present invention provides an interlocking overlapping double polymer membrane-based waterproofing coiled material, which solves the problem of poor tensile performance of the interlocking overlapping double polymer membrane-based waterproofing coiled material in the related art.

[0004] The technical solution of the present invention is as follows:

[0005] The present invention provides an interlocking overlapping double polymer membrane-based waterproofing coiled material, comprising a first permeable reactive adhesive layer, a first polymer membrane base layer, a second permeable reactive adhesive layer, a second polymer membrane base layer, a third permeable reactive adhesive layer, and a first isolation film layer, which are arranged in sequence from top to bottom; an overlapping opening is arranged at one end of the second permeable reactive adhesive layer, a second isolation film layer is arranged on the upper surface of the overlapping opening, and a third isolation film layer is arranged on the lower surface of the overlapping opening; a fourth isolation film layer is arranged on the upper surface of one end of the first permeable reactive adhesive layer away from the overlapping opening, and an anti-adhesion and viscosity-reducing layer is arranged on the upper surface of the other end;

[0006] The surface of the first polymer film base layer and the surface of the second polymer film base layer each independently have raised stripes;

[0007] The first osmotic reactive adhesive layer, the second osmotic reactive adhesive layer and the third osmotic reactive adhesive layer each independently have a depression matched with the raised stripes;

[0008] The depressions are formed by needle-shaped mineral crystals.

[0009] As a further technical solution, the average spacing distance between the raised stripes is 5-10 μm.

[0010] As a further technical solution, the raised stripes are straight or curved stripes.

[0011] As a further technical solution, the needle-shaped mineral crystals are calcium sulfate whiskers or needle-shaped wollastonite crystals, and the diameter of the needle-shaped mineral crystals is 50-200 nm and the length is 0.2-10 μm.

[0012] As a further technical solution, the surface of the first polymer film base layer and the surface of the second polymer film base layer are independently treated with corona treatment or sodium naphthalene treatment solution.

[0013] As a further technical solution, the first polymer film base layer and the second polymer film base layer are each independently a polyethylene terephthalate film base layer containing inorganic particles.

[0014] After the surface of the polymer membrane base layer is treated with corona treatment or sodium naphthalene treatment solution, a part of the inorganic particles contained therein can be exposed, thereby enhancing the interfacial activity and surface roughness of the polymer membrane base layer, and helping to improve the bonding ability between the polymer membrane base layer and the penetration reaction adhesive layer, thereby further improving the tensile properties of the bite-type overlapped double polymer membrane-based waterproof membrane.

[0015] As a further technical solution, the inorganic particles are mineral particles or chemically crystallized particles. The mineral particles are naturally formed, such as calcium carbonate, dolomite, wollastonite, barite, and calcium sulfate, and the particle size is usually 50~500nm; the chemically crystallized particles are artificially formed through chemical reactions, such as calcium carbonate, calcium sulfate, and silicon dioxide obtained by chemical crystallization, and the particle size is usually 5~300nm.

The use of ternary hydroxyl vinyl chloride resins and ternary carboxyl vinyl chloride resins can strengthen the internal bonding, thereby further improving the tensile properties of the interlocking overlapped double polymer membrane-based waterproofing membrane. In addition, the addition of bauxite can also further improve the tensile properties of the interlocking overlapped double polymer membrane-based waterproofing membrane.

[0020] As a further technical solution, the weight ratio of the trivalent hydroxy chloroacetic acid resin to the trivalent carboxyl chloroacetic acid resin is 2-4:1.

[0021] When the weight ratio of ternary hydroxy vinyl chloride resin to ternary carboxyl vinyl chloride resin is 2-4:1, the tensile properties of the interlocking overlapped double polymer membrane-based waterproofing membrane can be further improved.

[0022] As a further technical solution, the bauxite is bauxite modified by imide compounds.

[0023] Surface modification of bauxite using imide compounds can not only improve the dispersibility of bauxite, but also strengthen the interaction with ternary vinyl chloride resin and styrene-butadiene-styrene copolymer, thereby further improving the tensile properties of the interlocking overlapped double polymer membrane-based waterproofing membrane.

[0024] As a further technical solution, the preparation method of the imide compound modified bauxite includes the following steps: dissolving the imide compound in anhydrous ethanol to obtain an imide compound solution, adding bauxite to the imide compound solution, stirring, and concentrating to obtain the imide compound modified bauxite.

[0025] As a further technical solution, the weight ratio of the bauxite to the imide compound is 9~14:1.

[0026] When the weight ratio of bauxite to imide compounds is 9-14:1, the tensile properties of the interlocking overlapped double polymer membrane-based waterproof membrane can be further improved.

[0027] As a further technical solution, the bauxite is calcined bauxite.

[0028] As a further technical solution, the preparation method of the imide compound modified bauxite comprises the following steps:

[0029] A1. calcining and grinding bauxite to obtain calcined bauxite;

[0030] A2. Dissolving an imide compound in anhydrous ethanol to obtain an imide compound solution, adding the calcined bauxite to the imide compound solution, stirring, and concentrating to obtain the imide compound-modified bauxite.

[0031] After calcining bauxite, its surface is modified by using imide compounds, which can further improve the tensile properties of the interlocking overlapping double polymer membrane-based waterproof membrane.

[0032] As a further technical solution, the imide compound includes one or more of phthalimide, N-bromosuccinimide, and N-phenylmaleimide.

[0033] As a further technical solution, during the calcination, the temperature is 600-700° C. and the time is 1-2 hours.

[0034] As a further technical solution, the mass fraction of the imide compound solution is 3% to 10%.

[0035] As a further technical solution, the anti-adhesion and viscosity-reducing layer is a mineral sand layer.

[0036] As a further technical solution, the first isolation film layer, the second isolation film layer, the third isolation film layer and the fourth isolation film layer are each independently a removable isolation film layer, and the material is a PE film.

[0037] As a further technical solution, the fourth isolation film layer has the same size as the second isolation film layer and the third isolation film layer.

[0038] As a further technical solution, the plasticizer is one or both of dioctyl phthalate and diisononyl phthalate.

[0039] As a further technical solution, the antioxidant is one or more of antioxidant 1010, antioxidant 1076, and antioxidant 168.

[0040] The present invention also provides a method for preparing a bite-type overlapping double polymer membrane-based waterproofing coiled material, comprising the following steps:

[0041] S1, heating the asphalt to 185-195° C., and mixing it evenly with the other raw materials of the first permeable reaction adhesive layer to obtain a first permeable reaction adhesive layer mixture;

[0042] S2, heating the asphalt to 185-195° C., and uniformly mixing it with the remaining raw materials of the second permeable reaction adhesive layer to obtain a second permeable reaction adhesive layer mixture;

[0043] S3, heating the asphalt to 185-195° C., and uniformly mixing it with the remaining raw materials of the third permeable reaction viscose layer to obtain a third permeable reaction viscose layer mixture;

[0044] S4, sequentially preparing a first polymer film base layer, a second polymer film base layer and a first isolation layer from top to bottom, coating the first permeable reaction adhesive layer mixture on the upper surface of the first polymer film base layer, coating the second permeable reaction adhesive layer mixture between the first polymer film base layer and the second polymer film base layer, coating the third permeable reaction adhesive layer mixture between the second polymer film base layer and the first isolation film layer, and calendering to obtain a first permeable reaction adhesive layer coated on the upper surface of the first polymer film base layer, a second permeable reaction adhesive layer coated between the first polymer film base layer and the second polymer film base layer, and a third permeable reaction adhesive layer coated between the second polymer film base layer and the first isolation film layer;

[0045] S5. An overlapping opening is set at one end of the second permeable reactive adhesive layer, a second isolation film layer is covered on the upper surface of the overlapping opening, a third isolation film layer is covered on the lower surface of the overlapping opening, a fourth isolation film layer is covered on the upper surface of one end of the first permeable reactive adhesive layer away from the overlapping opening, and an anti-sticking and viscosity-reducing layer is covered on the upper surface of the other end of the first permeable reactive adhesive layer away from the overlapping opening to obtain an interlocking overlapping double polymer membrane-based waterproofing membrane.

[0046] As a further technical solution, in steps S1, S2 and S3, the temperature is reduced to 135-145° C. after the mixing is uniform.

[0047] The working principle and beneficial effects of the present invention are:

[0048] In the present invention, the surface of the first polymer membrane base layer and the surface of the second polymer membrane base layer each independently have raised stripes, the first permeable reactive adhesive layer, the second permeable reactive adhesive layer and the third permeable reactive adhesive layer each independently have depressions matched with the raised stripes, the depressions are formed by needle-shaped mineral crystals, and the needle-shaped mineral crystals can form an interlaced mosaic structure with the raised stripes. When a relative sliding tendency occurs between the permeable reactive adhesive layer and the polymer membrane base layer, the ends of the needle-shaped mineral crystals will be blocked by the raised stripes of the polymer membrane base layer, thereby strengthening the bonding between the permeable reactive adhesive layer and the polymer membrane base layer, thereby improving the tensile properties of the bite-type overlapped double polymer membrane-based waterproof membrane.
