Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite template materials, and in particular to a bituminous composite template made of recycled materials. BACKGROUND

[0002] Green plant material waste is generated in large quantities in various greening projects. The waste usually includes one or more of branches, leaves, tree bark, shrubs, and flower branches and leaves. Existing methods for treating green plant material waste include backfilling, incineration, and composting. Backfilling involves directly burying the green plant material waste after the project is completed. This method is simple but resource-intensive. Incineration can quickly dispose of large amounts of green plant material waste, but it produces harmful gases during combustion, which is not conducive to environmental protection. The composting method can convert green plant material waste into fertilizer and improve soil structure, but it takes a long time and is limited by environmental conditions, making it difficult to operate.

[0028] The following will be described in detail in combination with the accompanying Figures 1-2 Further detailed description of the present application.

[0029] Embodiments of the present application disclose a kind of asphalt composite template made of recycled materials.

[0030] The asphalt composite template is light in weight, environmentally friendly, waterproof, oil-proof, not easy to mildew, strong in flexibility, can be bent, and has long service life, temperature resistance can reach-15 ℃ ~ 60 ℃. Although it will not melt when it exceeds 60 ℃, but flexible deformation will occur, on the one hand, it can meet the needs of being molded into an ideal shape by simply heating the composite template on the construction site, on the other hand, it will not be damaged by its own stress when deformed due to changes in environmental temperature. It can be applied to template processing and installation of various civil engineering, and can also be applied to various fields with requirements of moisture-proof, heat insulation, shock absorption, etc., culvert, tunnel concrete water joint plate, bridge joint water stop plate.

[0031] Embodiment 1

[0032] This application provides an asphalt composite template made of recycled materials, including a core material 1 and a protective layer 2 covering the core material 1. The core material 1 includes waste greening plant materials and waste tire shreds, and the protective layer 2 includes concrete. By rationally utilizing waste greening plant materials and waste tire shreds, the recycling of waste greening plant materials and waste tires is realized, improving resource utilization. At the same time, it solves the problem of waste greening plant materials and waste tire disposal and reduces environmental pollution.

[0033] Specifically, waste materials from landscaping plants include one or more of the following: branches, leaves, bark, shrubs, and withered branches and leaves of flowers. Among these, the long and tough fibers of leaves, flowers, and branches are suitable for enhancing the mechanical properties of the core material 1; the bark is rich in natural gums, which helps to improve the bonding performance of the core material 1.

[0034] Protective layer 2 includes concrete. The concrete can be milled material recycled from old pavement and screened to remove stones, as well as waste waterproof membrane that has reached its service life due to long-term oxidation and aging. This reduces costs and achieves resource reuse.

[0035] Milled aggregate from old road demolition contains a large amount of recycled asphalt and mineral aggregates. Unlike freshly mixed asphalt, this aggregate exhibits high variability and complex structural composition, resulting in a lack of toughness in the asphalt when reused. Similarly, the asphalt in waste waterproofing membranes also lacks toughness. Furthermore, waste waterproofing membranes contain not only asphalt but also resins and plastics, with an asphalt content of 60%-70%. By mixing and heating the milled aggregate with waste waterproofing membranes, the toughness of the concrete can be increased through the resins and plastics.

[0036] like Figure 1 As shown, when the core material 1 is sheet-like, it is formed by repeatedly hot-pressing waste green plant materials and waste tire shreds. The waste tire shreds increase the toughness of the core material. During this process, milled material and waste waterproof membrane are melted with engine oil or diesel. The final concrete can be evenly covered on the entire surface of the core material 1 by soaking or coating, forming a dense protective layer 2. The advantage of this method is that it can ensure the structural strength of the asphalt composite formwork.

[0037] The implementation principle of this embodiment is as follows: by rationally utilizing waste greening plant materials, milled material, waste waterproof membrane, and waste tires, waste recycling of waste is achieved, improving resource utilization efficiency, solving the waste disposal problem, and reducing environmental pollution. Furthermore, using waste as raw materials significantly reduces production costs. Simultaneously, it improves the physical properties of the asphalt composite formwork, resulting in superior overall product performance.

[0038] Example 2

[0039] As Figure 2 shown, the embodiment differs from the above-mentioned embodiments in that the core material 1 is configured in a fluffy shape and is formed by crushing green plant material waste and waste tire powder. At this time, the milling material and the waste waterproof roll material are melted by machine oil or diesel oil to form mixed material and are coated on the core material 1 by stirring and mixing. When the asphalt in the milling material is modified asphalt, the melting temperature is controlled at about 190°C; when it is medium temperature asphalt, the melting temperature is controlled between 130°C and 150°C. The time for heating the asphalt to the melting state varies with the type of asphalt, heating temperature and environmental conditions, and too high melting temperature or too long heating duration will adversely affect the performance of the asphalt, such as decomposition, aging, reduction of bonding performance, etc. Generally speaking, under standard heating conditions, most asphalts begin to melt when they reach the melting temperature and the temperature is maintained for not less than 30 minutes. The rubber constituting the tire will undergo softening, solidification and other changes in the range of 150°C to 200°C. The melting temperature of different types of rubber is different, for example, the melting temperature of natural rubber is about 160°C, while the melting temperature of synthetic rubber is more than 200°C. However, the rubber will harden and become brittle when heated at high temperature. This will affect the chemical stability of the rubber and reduce the bonding force of the rubber, accelerating the aging process of the rubber. (The rubber will age when heated at high temperature, mainly manifested as decomposition of sulfides and chemical chain rupture) The rubber will also cause surface oxidation when it is in a high temperature environment for a long time, which will reduce the performance of the rubber. After the rubber ages, the elasticity decreases and the tensile strength decreases, resulting in failure of the original elastic performance of the rubber.

[0040] In summary, the optimal fusion temperature before mixing the mixed material with the core material 1 should be controlled between 150°C and 200°C, and the whole process should be controlled within 30 minutes to 1 hour. Finally, the fluid composite material after mixing is poured into a mold with a normal building template size such as 183x92x2cm, 120x245x2cm, etc., and is evenly spread and formed by repeatedly rolling with a road roller. Finally, the plate-shaped composite material is formed after demolding.

[0041] The implementation principle of the embodiment is that by adopting the flocculent core material 1, the production difficulty and cost can be reduced without sacrificing the product performance, and the whole production process is simplified. Meanwhile, by mixing and molding by stirring to coat the coagulation material, the uniformity and stability of the protective layer 2 can be better ensured. The asphalt composite formwork has the advantages of asphalt, and has the strength of wood chips and the toughness of tires, is waterproof, oil-proof, and not easy to mildew, and has a long service life, and can resist temperature of-15 DEG C to 60 DEG C. The asphalt composite formwork made of the recycled material provided in the application will be deformed flexibly when the temperature exceeds 60 DEG C, on the one hand, the formwork will not be damaged by its own stress when deformed due to the change of ambient temperature, and on the other hand, the formwork can be molded into an ideal shape by simple heating in the construction site. The asphalt composite formwork can be applied to the formwork processing and installation of various civil engineering projects, and can also be applied to various fields requiring moisture-proof, heat insulation, shock absorption, etc., culverts, tunnel concrete water joint plates, and bridge joint water stop plates.

[0042] The two embodiments of the application make reasonable collocation of different types of green plant material waste and waste materials, so that the final product has higher added value and broader application prospect.

[0043] The above are preferred embodiments of the application, and do not limit the protection scope of the application, therefore: all equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
