| 中文摘要: |
| 为了提升绿色储粮效能，系统对比研究了粮仓外壁喷涂高反射纳米复合隔热涂料与传统乳胶漆涂料的隔热、防水及气密性能。实验在多种仓型（高大平房仓、浅圆仓、立筒仓等）中进行。研究表明，高反射纳米复合隔热涂层凭借高太阳反射比主动阻隔太阳辐射热，有效削弱外部热源对仓内环境的影响。这种主动式隔热机制导致：与涂刷传统乳胶漆涂料相比，仅改造外墙后，夏季仓外壁温度可降低5～7℃，热量内传延迟使仓温降低3～9℃，上层粮温降低3～4℃，全仓平均粮温降低2～3℃。同时，高反射纳米复合隔热涂层形成的连续、致密膜层结构，使其在防水渗透性和仓体气密性方面亦表现出更优的性能。本研究表明，高反射纳米复合隔热涂料通过光热反射和物理阻隔系统机制，有效减少冷量损失、降低储粮能耗、延缓粮食品质劣变等方面展现出巨大潜力，为推进绿色低碳储粮技术发展提供了有效的材料解决方案。 |

| To improve the efficiency of green gtain storage, a systematic comparative study was conducted on the thermal insulation, wateproofing, and airtightness performanc of high-reflective nanocomposite thermal insulation coatings versus traditional latex paint coatings applied to granary exterior walls. Experiments were carried out on multiple types of granaries, including tall bungalow granaries, squat silos, and vertical silos. Results showed that, owing to its high solar reflectance, the high-reflective nanocomposite coating actively blocks solar radiation heat and effectively mitigates the influence of external heat sources on the granary interior. This active insulation mechanism led to substantial cooling effects: compared with traditional latex paint, exterior wall temperatures in summer were reduced by 5-7 ℃, granary interior temperatures by 3-9 ℃, upper grain temperatures by 3-4 ℃, and the average grain temperature across the entire granary by 2-3 ℃, even when only the exterior walls were renovated. Furthermore, the continuous and dense film structure of the coating exhibited superior waterproofing and airtightness. These findings indicate that high-reflective nanocomposite thermal insulation coatings, through combined photothermal reflection and physical barrier mechanisms, can effectively reduce cooling energy loss, lower storage energy consumption, and delay grain quality deterioration, offering a promising material solution for the advancement of green and low-carbon grain storage technologies. |
