背景技术 Background technique
相变蓄能建筑材料是通过对传统建筑材料的改良而形成的一种新型的建筑节能材料，它能够在环境温度超过材料的相变温度时利用材料本身的相变进行蓄能，在温度低于材料的相变温度时发生反向的相变放出热量，实现能量的自我调节，达到降低室内温度波动，从而达到节能和提高环境舒适度的作用。相变材料(PCM)是利用相变过程中吸收或释放的热量来进行潜热蓄能的物质，具有在一定温度范围内改变其物理状态的能力。相变蓄能建筑材料是通过向传统的建筑材料中加入相变材料研制而成的。通常情况下相变蓄能材料可以添加到墙体、地板中使用，用于建筑室内的蓄能节能。但现有相变蓄能材料存在价格普遍偏高的缺点，不能被广泛的应用与推广。Phase change energy storage building material is a new type of building energy-saving material formed by improving traditional building materials. It can use the phase change of the material itself to store energy when the ambient temperature exceeds the phase change temperature of the material. Reverse phase transition occurs at the phase transition temperature of the material to release heat, realize energy self-regulation, reduce indoor temperature fluctuations, thereby achieving energy saving and improving environmental comfort. Phase change material (PCM) is a substance that uses the heat absorbed or released during the phase change process to store latent heat energy, and has the ability to change its physical state within a certain temperature range. Phase change energy storage building materials are developed by adding phase change materials to traditional building materials. Generally, phase change energy storage materials can be added to walls and floors for energy storage and energy saving in building interiors. However, the existing phase-change energy storage materials have the disadvantage of generally high prices, and cannot be widely used and promoted.

实施例3Example 3
首先配制饱和的NaCl的水溶液，将与NaCl饱和水溶液质量比为1∶1的熔化的液态沥青不断滴加到饱和的NaCl的水溶液中，并不断高速搅拌，使沥青均匀的分散于NaCl的饱和水溶液中，最终形成稳定的沥青乳化液。其固-液相变转化温度为21℃。First prepare a saturated NaCl aqueous solution, continuously drop the molten liquid asphalt with a mass ratio of 1:1 to the saturated NaCl aqueous solution, and keep stirring at a high speed, so that the asphalt is evenly dispersed in the NaCl saturated aqueous solution Finally, a stable asphalt emulsion is formed.
