The SGR-Non-cured rubber Asphalt Waterproof coating Non-curable creep-type rubber Asphalt Waterproof coating adopts rubber and Asphalt as main components, and is added with an auxiliary agent to be mixed to prepare the Waterproof coating which keeps a viscous paste body within the service life. The non-cured creep rubber asphalt waterproof coating, hereinafter referred to as a non-cured coating, is a novel creep waterproof material which takes rubber powder, asphalt and special additives as main raw materials and keeps a sticky paste for a long time in an application state. The coating can seal base cracks and capillary holes and can adapt to complex construction working faces; the self-healing adhesive does not solidify for a long time after contacting with air, always keeps the characteristics of sticky colloid, has strong self-healing capability, is sticky when being touched and difficult to peel, and still has good adhesive property at the temperature of minus 20 ℃. The waterproof layer can solve the problems of cracking, flexural fatigue or advanced aging of the Schlegger Guest and Guest under a high stress state and the like of the waterproof layer caused by the fact that the cracking stress of the base layer is transmitted to the waterproof layer; meanwhile, due to the viscosity of the creep material, the creep material can well seal pores and cracks of a base layer, so that the problem of water channeling of a waterproof layer is solved, and the waterproof reliability is greatly improved; can also solve the problem of compatibility when the existing waterproof coiled material and waterproof paint are used in a compounding way.
The product has the advantages of creep crack resistance, wet adhesion, sealing property, self-healing property, water channeling resistance, bidirectional tear resistance, ageing resistance, low temperature resistance, high peeling, high strength and the like.
Creep cracking resistance: the influence of the stress of the base layer on the waterproof layer is eliminated through the creep of the coiled material. The creep self-adhesive waterproof roll is processed by linear high-molecular acrylate materials, when the roll is deformed and stretched by a base layer, long-chain high molecules of creep materials in the roll slide mutually to achieve leveling along with the change of the base layer, and the stress in the roll is suddenly reduced or even disappears, so that the waterproof layer is not stretched, and the waterproof layer is prevented from cracking or is in a high stress condition for a long time to accelerate aging.
Wet adhesion: the web can be constructed on a wet base. The long-chain molecules of the coiled material body contain rich hydrophilic chain segments, and free bonds formed by the chain segments are equivalent to claws and can extend into pores on the surface of the base layer to firmly grasp the microstructure of a base surface to form a porous structure. The hydrophilic chain segments of the creep molecules can either extend directly into the pores of the cement colloid or can be brought into the pores of the cement colloid through water molecules.
Self-healing property: after the coiled material is damaged or punctured by a foreign object, the soft material can automatically leave the hole to flow to eliminate the internal stress of the hole, and meanwhile, the hydrophilic chain segment of the molecules in the coiled material can absorb water to slightly expand to self-heal the defect after meeting water, so that water is prevented from passing through, the generation of the phenomenon of water channeling is prevented, and the waterproof reliability is improved.
Water channeling prevention: prevention of water breakthrough needs to be addressed by full stickiness of the web. Because the microstructure of the waterproof base surface is not flat, the thickness of the bonding layer is not enough or the softness is not enough, the bonding material can not reach the microscopic recesses of the base surface, and the microscopic convex parts only bonded to the base surface can firmly bond the coiled material and the base surface, but can not thoroughly prevent the generation of water leakage. The creep bonding layer of the macromolecule creep deformation self-adhesive coiled material is thick, soft enough and capable of being completely bonded with a base surface to achieve the 'full' effect.
Excellent low temperature adaptability: the matrix of the coiled material is made of high polymer material with good low-temperature flexibility, and the creep layer is made of propionate monomer with low glass transition temperature, good water-based property, good gas property and good aging resistance, so that the coiled material can be constructed at low negative temperature.
The SGR-strong cross laminated film self-adhesive waterproof roll is a novel environment-friendly waterproof material, and is a great breakthrough of the production technology and the construction technology of the self-adhesive waterproof roll. It uses synthetic rubber, high-quality heavy traffic asphalt, tackifier, anti-aging agent, etc. as base material, uses imported strong film as surface material, adopts antisticking isolating paper film as self-adhesive water-proof coiled material of isolating layer, its product characteristic:
1. and (3) water proofing: high hydrostatic pressure resistance;
2. density cross laminated polyethylene film: has excellent dimensional stability and puncture resistance;
3. single-layer coiled material: the field construction and installation are convenient;
4. cold construction: no heating is needed, and no fire hazard exists;
5. self-adhesive modified asphalt: continuity can be ensured at the lap joint, and the unique formulation allows for sealing around the small penetration;
6. chemical resistance: the thickness is prefabricated, and the field use is unchanged;
7. wide coiled material: the width of 2m can be realized, the large-area construction is facilitated, and the hidden danger of overlapping and leakage is reduced.
To be further described, the thickness of the first waterproof layer body 51 is 1.5mm or 3mm, wherein when a polymer reaction bonding type self-adhesive waterproof roll is used, the thickness is 1.5mm; when the SGR-strong cross laminated film self-adhesive waterproofing roll is used, the thickness is 3mm.
To be further described, the thickness of the second waterproof layer body 52 is 2mm.
To explain further, the protective layer 6 is made of fine-grained concrete, and the fine-grained concrete has the following advantages: 1. and the good compactness of the concrete is ensured. 2. The production efficiency is improved. Because the concrete does not need to be vibrated, the time required by concrete pouring is greatly shortened, the labor intensity of workers is greatly reduced, and the number of the required workers is reduced. 3. Improve the working environment and the safety. The vibration noise is avoided, and arm vibration syndrome caused by the fact that a worker holds the vibrator for a long time is avoided. 4. Improve the surface quality of the concrete. No surface bubbles or honeycomb pitted surface occurs, and surface repair is not needed; the texture or the sculpt of the surface of the template can be vividly presented. 5. The degree of freedom of the structural design is increased. The structure with complex shape, thin wall and dense reinforcement can be cast without vibration. Previously, such structures have often been limited in their adoption due to difficulties in concrete placement. 6. The abrasion of the template caused by vibration is avoided. 7. Reduce the abrasion of the concrete to the mixer. 8. The overall construction cost of the project can be reduced. The cost is reduced from the aspects of improving the construction speed, limiting the noise by the environment, reducing the labor, ensuring the quality and the like.
Further, the thickness of the protective layer 6 is 40mm, and bidirectional steel bars are arranged in the protective layer 6, wherein the bidirectional steel bars are 3m × 3m in cells, the width of each slot is 20mm, and the bidirectional steel bars are embedded and sewn in the protective layer 6 through sealant, so that the structural stability of the protective layer 6 is enhanced, and the protective effect is achieved.
Further, the concrete slope layer 2 is made of lightweight aggregate concrete, and the lightweight aggregate concrete has the following advantages: light dead weight, good heat preservation and insulation performance, good fire resistance and the like. The compressive strength of the structural light aggregate concrete can reach 70 MPa, and compared with the common concrete with the same grade, the structural heat-preservation dry-mixed composite light aggregate concrete can reduce the self weight by more than 20-30 percent, is a wall material with good heat preservation performance, has the heat conductivity of 0.233-0.523W/(meter open), and is only 12-33 percent of the common concrete. The lightweight aggregate concrete has good deformation performance and lower elastic modulus. In general, shrinkage and creep are also large. The modulus of elasticity of lightweight aggregate concrete is directly proportional to its bulk weight and strength. The smaller the bulk weight, the lower the strength, and the lower the elastic modulus. Compared with common concrete with the same grade, the elastic modulus of the lightweight aggregate concrete is about 25 to 65 percent lower.
As shown in fig. 1, a gas barrier layer 7 is arranged between the concrete slope layer 2 and the heat insulating layer 3, so that the heat insulating layer 3 is prevented from affecting the concrete slope layer 2 due to high-temperature hot gas.
Further, an exhaust pipe is arranged in the concrete slope finding layer 2 and used for discharging hot gas emitted by the heat insulation layer 3 to the outside through the exhaust pipe, so that the condition that the heat insulation layer 3 causes certain influence on the concrete slope finding layer 2 due to the high-temperature hot gas is avoided.
To explain further, the surface layer 1 is made of reinforced concrete, wherein when the surface layer 1 is coated with other coatings, shot blasting treatment needs to be performed on the surface layer 1.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
