【摘要】：针对我国人口数量巨大、城市快速发展、建筑采暖能耗高等问题,研究新型建筑节能技术非常必要。本文在外墙外保温的基础上,对外墙保温材料进行新的开发研究。以双氧水为发泡剂,以普通硅酸盐水泥、铝酸盐水泥、粉煤灰为胶凝体系,并在其他助剂的作用下来制备墙体保温材料,并对各原材料进行分析研究;并将试验研究的墙体保温材料进行工业化生产后应用于具体的工程当中,并结合工程情况,对施工方案进行了详细介绍,最后,并将本文研究的墙体保温材料进行现场得隔热试验对比。研究结果表明:通过对墙体保温材料的性能影响因素的试验分析,水灰比、粉煤灰掺量、双氧水、稳泡剂量、聚丙烯增强纤维、减水剂量、碳酸锂、催化剂等对墙体保温材料的干密度、导热系数、抗压强度、抗折强度都有着影响,墙体保温材料在施工过程中需要解决一些关键性问题;对本方案的墙体保温材料、EPS板、纯水泥基材板的三种材料在相同4cm厚度下,采用热箱-热流计法进行现场热阻检测,结果表明本方案的墙体保温材料的热阻值较高,相对其他两种墙面材料具有较好的阻热效果。
[Abstract]:In view of the problems of large population, rapid development of cities and high energy consumption of building heating, it is necessary to study new building energy saving technology. On the basis of exterior wall thermal insulation, this paper makes a new research on exterior wall insulation material. Using hydrogen peroxide as foaming agent, ordinary Portland cement, aluminate cement and fly ash as gelling system, and under the action of other auxiliaries, the wall insulation material is prepared, and the raw materials are analyzed and studied. And the wall insulation materials studied in the experimental industrial production of the application in specific projects, and combined with the engineering situation, the construction scheme is introduced in detail, finally, And the wall insulation material studied in this paper is compared with the field thermal insulation test. The results show that the factors affecting the properties of wall insulation materials are as follows: water / cement ratio, fly ash content, hydrogen peroxide, foam stabilization dose, polypropylene reinforced fiber, water reducing agent, lithium carbonate, The catalyst has an effect on the dry density, thermal conductivity, compressive strength and flexural strength of the wall insulation material, and some key problems need to be solved in the construction process of the wall insulation material. Under the same thickness of 4cm, the three kinds of materials of pure cement substrate were tested by the method of heat box and heat flow meter. The results show that the heat resistance of the wall insulation material of this scheme is high. Compared with the other two metope materials, it has better heat resistance effect.
