与现有技术相比，本发明的单组份储热灌封材料具有以下有益效果：本发明的单组份储热灌封材料，性能如下：比热容(J/(g·K))≥2.0；相变焓(J/g)约30～180，即吸热值；相变温度(℃)25～90；比重(g/cc)：0.8～1.8表干时间：5min～10min；固化时间：1h～2h；完全固化时间≥24h；相变材料为石墨吸附相变储能粉体或者气凝胶吸附相变储能粉体；Compared with the prior art, the single-component heat storage potting material of the present invention has the following beneficial effects: the single-component heat storage potting material of the present invention has the following performance: specific heat capacity (J/(g·K)) ≥ 2.0 ; Phase change enthalpy (J/g) is about 30～180, which is the endothermic value; Phase change temperature (℃) 25～90; Specific gravity (g/cc): 0.8～1.8 Surface drying time: 5min～10min; curing time: 1h～2h; complete curing time ≥24h; phase change material is graphite adsorption phase change energy storage powder or aerogel adsorption phase change energy storage powder;
其中，石墨吸附相变储能粉体选用了蠕虫状膨胀石墨作为吸附材料，蠕虫状膨胀石墨由天然鳞片石墨经插层、水洗、干燥、高温膨化得到的一种疏松多孔的蠕虫状物质，膨胀石墨除了具备天然石墨本身的耐冷热、耐腐蚀、自润滑、 耐辐射、导电性等优良性能以外，还具有天然石墨所没有的柔软、压缩回弹性、吸附性、生态环境协调性、生物相容性、耐辐射性等特性，由于疏松多孔，比表面积大，因此对相变粉体的吸附能力非常强，只需要采用较少重量份的蠕虫状膨胀石墨就可以完成对相变材料的吸附，当然，蠕虫状膨胀石墨不能太少，太少无法完全吸附住相变材料；蠕虫状膨胀石墨也不能太多，太多的话一方面增加成本和降低产品的热焓值，同时，降低了石墨吸附相变储能粉体相变焓，降低了产品的储热性能，因此，针对不同的粉体，恰好能够完全吸附完相变粉体的重量比是最优的；Among them, the graphite adsorption phase change energy storage powder uses vermicular expanded graphite as the adsorption material. The vermicular expanded graphite is a loose and porous vermicular substance obtained by intercalation, washing, drying, and high temperature expansion of natural flake graphite. In addition to the excellent properties of natural graphite, such as resistance to cold and heat, corrosion resistance, self-lubricating, radiation resistance, and electrical conductivity, graphite also has softness, compression resilience, adsorption, ecological environment coordination, and biological characteristics that natural graphite does not have. Capacitive, radiation resistance and other characteristics, due to loose and porous, large specific surface area, so the adsorption capacity of phase change powder is very strong, only need to use less weight parts of worm-like expanded graphite to complete the adsorption of phase change materials Of course, the worm-like expanded graphite cannot be too little, too little can not completely adsorb the phase change material; the worm-like expanded graphite can not be too much, on the one hand, if it is too much, it will increase the cost and reduce the enthalpy value of the product, and at the same time, it will reduce the graphite The phase change enthalpy of the adsorption phase change energy storage powder reduces the heat storage performance of the product. Therefore, for different powders, the weight ratio of the phase change powder that can be completely absorbed is the optimal;
而为了进一步减少蠕虫状膨胀石墨的使用量，在其制备方法的步骤2中，采用了真空吸附的工艺，在真空条件下搅拌，熔化的相变粉体更容易深入地渗透到蠕虫状膨胀石墨蓬松的深孔内，深孔内对相变材料的吸附作用远远大于常规的浸渍或者搅拌，相变材料进入深孔内之后，在高温条件下也难以溢出，具有超常的吸附性能，如此，尽量少的蠕虫状膨胀石墨吸附了更多的相变材料，石墨吸附相变储能粉体的相变焓增加了5％-10％，性能得到了大幅提升，由于减少了蠕虫状膨胀石墨的用量，成本也大幅降低；In order to further reduce the amount of worm-like expanded graphite used, in step 2 of its preparation method, a vacuum adsorption process is adopted. When stirring under vacuum conditions, the molten phase change powder can penetrate into the worm-like expanded graphite more easily. In the fluffy deep hole, the adsorption effect of the phase change material in the deep hole is far greater than that of conventional immersion or stirring. After the phase change material enters the deep hole, it is difficult to overflow under high temperature conditions, and has exceptional adsorption performance. As few worm-like expanded graphite as possible adsorb more phase change materials, the phase change enthalpy of graphite adsorption phase-change energy storage powder has increased by 5%-10%, and the performance has been greatly improved. Due to the reduction of the worm-like expanded graphite The amount and cost are also greatly reduced;
气凝胶吸附相变储能粉体选用了气凝胶作为吸附材料，气凝胶导热系数低，保温隔热效果好，理化性质稳定，高温不燃，完全防水，且无毒害，绿色环保，且比表面积大，对相变粉体的吸附能力非常强，只需要采用较少重量份的气凝胶就可以完成对相变材料的吸附，当然，气凝胶不能太少，太少无法完全吸附住相变材料；气凝胶也不能太多，太多的话一方面增加成本和产品的重量，同时，降低了气凝胶吸附相变储能粉体的相变焓，降低了产品的储热性能，因此，针对不同的相变粉体，恰好能够完全吸附完相变粉体的重量比是最优的；Aerogel adsorption phase change energy storage powder uses aerogel as the adsorption material. Aerogel has low thermal conductivity, good thermal insulation effect, stable physical and chemical properties, non-combustible at high temperature, completely waterproof, non-toxic, green and environmentally friendly, and The specific surface area is large, and the adsorption capacity for phase change powders is very strong. Only a small part of aerogel can be used to complete the adsorption of phase change materials. Of course, there should not be too little aerogel, too little can not be completely adsorbed Live phase change materials; too much aerogel can not be too much, if too much, on the one hand, it will increase the cost and the weight of the product, at the same time, it will reduce the phase change enthalpy of the aerogel adsorption phase change energy storage powder, and reduce the heat storage of the product. Performance, therefore, for different phase change powders, the weight ratio of the phase change powders that can be completely absorbed is the best;
而为了进一步减少气凝胶的使用量，在其制备方法的步骤2中，采用了真空吸附的工艺，在真空条件下搅拌，熔化的相变粉体更容易深入地渗透到气凝胶蓬松的深孔内，深孔内对相变材料的吸附作用远远大于常规的浸渍或者搅拌，相变材料进入深孔内之后，在高温条件下也难以溢出，具有超常的吸附性能，如此，尽量少的气凝胶吸附了更多的相变材料，气凝胶吸附相变储能粉体的密度提高了10-15％，而气凝胶吸附相变储能粉体的相变焓增加了5-15％左右，性能得到了大幅提升，由于减少了气凝胶的用量，成本也大幅降低。In order to further reduce the amount of aerogel used, in step 2 of its preparation method, a vacuum adsorption process is adopted, and the molten phase change powder is more easily penetrated into the fluffy aerogel by stirring under vacuum conditions. In the deep hole, the adsorption effect of the phase change material in the deep hole is far greater than that of conventional immersion or stirring. After the phase change material enters the deep hole, it is difficult to overflow under high temperature conditions, and has extraordinary adsorption performance. Therefore, as little as possible The aerogel adsorbed more phase change materials, the density of the aerogel adsorption phase change energy storage powder increased by 10-15%, and the phase change enthalpy of the aerogel adsorption phase change energy storage powder increased by 5 -15% or so, the performance has been greatly improved, and the cost is also greatly reduced due to the reduction in the amount of aerogel.
采用上述配方和制备方法的单组份储热灌封材料具备了优异的储热控温性能。The single-component heat storage potting material adopting the above formula and preparation method has excellent heat storage and temperature control performance.
