Description

Technical Field

[0001] The utility model belongs to the technical field of building materials, in particular to an externally coated BOPP brick-concrete recycled aggregate moisturizing board. Background Art

[0002] As global climate change intensifies, water scarcity has become a major constraint on agricultural production and ecological improvements. Traditional irrigation methods, particularly in arid and semi-arid regions, are not only inefficient but also waste a significant amount of precious water. Therefore, the development of new water-saving irrigation materials and technologies is crucial for improving water utilization efficiency and promoting sustainable agricultural development.

[0003] Among existing water-saving irrigation technologies, water-retaining materials are widely used in agricultural irrigation in arid regions due to their ability to store and slowly release water. However, traditional water-retaining materials often suffer from high costs, easy degradation, and unstable water retention, making them difficult to meet practical application requirements. Furthermore, some water-retaining materials may cause environmental pollution during use, limiting their widespread application.

[0004] In response to these issues, research into the use of waste construction materials and recycled resources to create water-retaining materials has recently begun to gain attention. Among these, brick-concrete recycled aggregate, a common construction waste, offers advantages such as low cost, widespread availability, and environmental friendliness after proper treatment, making it considered an ideal raw material for the production of water-retaining materials. Furthermore, BOPP (biaxially oriented polypropylene) film, due to its excellent waterproofness and breathability, is widely used in agricultural covering materials. Combining BOPP film with brick-concrete recycled aggregate to create a BOPP-coated brick-concrete recycled aggregate water-retaining material not only effectively improves water retention but also extends the material's service life and reduces its environmental impact.

[0005] However, there is no related product on the market that uses BOPP-coated brick-concrete recycled aggregate in moisturizing boards. Utility Model Content

[0006] To address the aforementioned technical issues, the present invention provides a BOPP brick-concrete recycled aggregate moisture-retaining board. Through its unique structural design, it effectively stores and slowly releases water, effectively reducing irrigation frequency and improving water resource utilization, providing an efficient and economical solution for agricultural irrigation in arid regions. This low-cost, environmentally friendly, and durable moisture-retaining board is suitable for arid and semi-arid regions, offering a new approach to agricultural irrigation.

[0007] The purpose of this utility model is achieved through the following technical solutions:

[0008] The utility model discloses an externally coated BOPP brick-concrete recycled aggregate moisturizing board, comprising a moisturizing board body, wherein a plurality of holes are staggeredly arranged on the upper end surface of the board body, and fillers are arranged in the holes, and the fillers are composed of a plurality of externally coated BOPP brick-concrete recycled aggregates; the externally coated BOPP brick-concrete recycled aggregates are composed of BOPP polymer material layers sequentially arranged on the periphery of dry recycled brick aggregates after removing the powder layer.

[0009] Furthermore, the externally applied BOPP polymer material layer adopts a single-sided adhesive BOPP tape.

[0010] Furthermore, the particle size of the dried recycled brick aggregate after removing the powder layer is 10-20 mm.

[0011] Furthermore, the length L of the moisturizing board is 0.5m to 1m, the width W is 0.5m to 1m, and the thickness H is 5cm to 15cm.

[0012] Furthermore, the aperture of the holes is slightly larger than the dry recycled brick aggregate particles after the powder layer is removed, and the aperture range is between 3 cm and 8 cm.

[0013] Furthermore, the edges of the holes on the plate body have a smooth transition structure.

[0014] The beneficial effects of the utility model are:

[0015] 1. Efficient water conservation and solid waste resource utilization.

[0016] This moisture-retaining panel innovatively combines waste brick-concrete materials with a layer of discarded BOPP polymer material, effectively storing and slowly releasing water, significantly improving irrigation efficiency and reducing water waste. Furthermore, the reuse of waste brick-concrete materials promotes the recycling of construction waste, meeting the requirements of sustainable development.

[0017] 2. Environmentally friendly and economical, reducing costs.

[0018] Based on low-cost, readily available waste brick and concrete and discarded BOPP materials, the moisture-retaining board is relatively inexpensive to produce. Its long-lasting water retention reduces the need for subsequent irrigation, further lowering the cost burden of agricultural production. Furthermore, the waterproof and breathable properties of the BOPP polymer layer avoid soil and other issues associated with traditional irrigation, protecting the ecological environment.

[0019] 3. Promote plant growth and improve agricultural production.

[0020] Moisture-retention panels provide a stable water environment for plants, ensuring normal growth in drought conditions and helping to improve crop yield and quality. Their wide applicability extends beyond farmland irrigation to include applications in urban landscapes such as flower beds and green belts, providing effective water support for various vegetation types and promoting the coordinated development of agriculture and urban greening.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example: This example uses construction solid waste as the main raw material to produce an external BOPP brick-concrete recycled aggregate moisturizing board, which achieves efficient water retention and is suitable for flower beds, deserts, arid areas, and planting areas. Figure 2-Figure 5 As shown, the utility model is a BOPP-coated brick-concrete recycled aggregate moisturizing board, including a moisturizing board body 1, a plurality of holes 2 are staggeredly arranged on the upper end surface of the board body 1, and fillers 3 are placed in the holes 2. The filler 3 is composed of a plurality of pieces of BOPP-coated brick-concrete recycled aggregate 4; the BOPP-coated brick-concrete recycled aggregate 4 is composed of a BOPP polymer material layer arranged on the periphery of the dry recycled brick aggregate with the powder layer removed.

[0029] like Figure 2-Figure 4As shown, the BOPP-coated brick-concrete recycled aggregate is prepared by the following steps: first, the brick aggregate is screened to select particles that meet the required particle size (in this case, 10-20 mm); then, it is washed to remove surface impurities; and then it is dried, with the drying temperature and time controlled to ensure that the aggregate is dry without damaging its structure. Next, a BOPP polymer layer is applied to the periphery of the dried recycled brick aggregate after the powder layer has been removed, forming a tightly wrapped structure. Brick-concrete recycled aggregate has a high water absorption rate. By applying a BOPP polymer layer to its outer surface, the BOPP polymer layer in this example is made of a single-sided adhesive BOPP tape commonly found in logistics waste, i.e., a single-sided adhesive BOPP film or transparent tape. A layer of translucent BOPP (biaxially oriented polypropylene) film or transparent tape is wrapped around the periphery of the brick-concrete recycled aggregate, effectively locking in moisture within the aggregate and achieving effective moisture retention. This layer not only allows rainwater or irrigation water to penetrate into the aggregate, but also, due to the micro-permeability of its structure or material itself, achieves an incomplete seal for moisture, preventing rapid evaporation of moisture under strong sunlight. The outer layer of BOPP film or transparent tape allows moisture to penetrate without evaporating easily, achieving a water-retention effect; the combination of the mixed recycled aggregate and the BOPP polymer material layer or transparent tape layer together constitutes a system that can both penetrate and slowly release moisture. The BOPP film or transparent tape is wrapped around the outside of the brick aggregate, and gaps are inevitably present between its strips. This application allows rainwater or irrigation water to penetrate smoothly into the interior of the brick-concrete recycled aggregate and fully utilizes its high water absorption properties. At the same time, the micro-permeability of the BOPP film or transparent tape can effectively prevent rapid evaporation of moisture under direct sunlight, thereby ensuring that a relatively stable humidity environment can be maintained inside the aggregate. The BOPP film or transparent tape not only provides a continuous and stable source of irrigation water for plants, but also further enhances the overall effectiveness of the moisturizing board.

[0030] like Figure 2 、 Figure 3 As shown, the moisturizing board body 1 is made of a weather-resistant and water-permeable material, ensuring that the board body 1 can withstand changes in the external environment for a long time while allowing moisture to penetrate the interior when needed. The board body 1 has a number of holes 2 evenly distributed throughout, staggered according to a pre-set arrangement, to optimize water retention and promote plant growth. The board body 1 has a length L of 0.5m to 1m and a width W of 0.5m to 1m. The thickness is adjusted according to specific needs, but should be sufficient to support the aggregate and prevent deformation. The thickness H is 5cm to 15cm.

[0031] like Figure 3 、 Figure 4As shown, the particle size of the recycled brick aggregate 4, after removing the powder layer and drying, has a core size range of 10-20 mm. This size refers to the original particle size before being wrapped with transparent tape. After being wrapped with a layer of BOPP polymer material or transparent tape, the overall particle size will increase slightly due to the additional thickness of the outer layer material, but this does not affect its suitability as a filler. The aperture 2 is slightly larger than the dried recycled brick aggregate particles after removing the powder layer (i.e., a core size of 10-20 mm, not considering the outer layer), and the specific aperture range is between 30 mm and 80 mm. This design ensures that the brick-concrete recycled aggregate 4 coated with BOPP film or transparent tape can be easily placed into the hole and firmly embedded therein through appropriate friction or fixing means. At the same time, this aperture design also reserves ample space not only for water storage but also for the extension and growth of plant roots, thus ensuring that the moisturizing plate not only provides continuous irrigation for plants but also promotes healthy plant growth. Maintain an appropriate distance between the holes to avoid mutual influence and ensure that each piece of aggregate can independently play a role in water retention.

[0032] The edges of the holes 2 on the plate body 1 have a smooth transition structure to prevent scratching or damage to the brick-concrete recycled aggregate coated with BOPP.

[0033] The plate structure of the utility model makes the moisturizing plate suitable for flower beds, deserts, and arid areas, providing a continuous water source for plant roots and reducing irrigation needs. Through the structural design of the utility model, the functions of moisturizing and storing water are achieved.

[0034] like Figure 2 As shown, when the present invention is working, first a moisturizing board body 1 is designed and manufactured according to actual needs, and holes 2 of a predetermined number and size are opened on it; then the aggregate is filled: the brick-concrete recycled aggregate 4 coated with BOPP film or transparent tape is combined into filler 3, and filled into the hole 2 one by one to ensure that the aggregate is tightly and firmly embedded in the hole; then installation and deployment are carried out: in actual use, the present invention is laid in flower beds, deserts, arid areas or tree planting areas. When it rains, rainwater can penetrate into the filler 3 through the holes 2 on the board body 1. Due to the wrapping gaps of the external BOPP film or transparent tape, rainwater can smoothly enter the interior of the aggregate, but when heated by the sun, it is difficult for water to evaporate from the aggregate, thereby continuously providing water to the roots of plants and reducing irrigation needs. Depending on the specific environmental conditions, multiple layers of moisture-retaining panels can be selectively laid. The laying method is flexible and can be laid with holes aligned or staggered to further enhance water retention. Finally, maintenance and monitoring: Regularly inspect the moisture-retaining panels, including the moisture retention of the aggregate, the integrity of the panels, and plant growth. Perform appropriate maintenance as needed, such as replenishing aggregate and adjusting the panel position.

[0035] The components not described in detail in this application are all existing conventional technologies and will not be described in detail.

[0036] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the scope of protection of the present invention.
