技术领域 technical field
本发明涉及一种建筑节能材料的制作方法，特别是涉及一种松香-CaCl2复合相变蓄能材料的制作方法。The invention relates to a manufacturing method of a building energy-saving material, in particular to a manufacturing method of a rosin- CaCl2 composite phase change energy storage material.
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 at the phase transition temperature of the material releases heat, realizes self-regulation of energy, reduces 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.

Rosin and CaCl2 are used as the main raw materials, and the raw materials are easy to obtain and low in cost.
具体实施方式 Detailed ways
实施例1Example 1
首先将一定量的松香加热至熔化，然后将CaCl2与松香质量比为1∶50的CaCl2粉末倒入熔化的松香中，对混合物搅拌，直至CaCl2完全熔解于松香之中。最终形成的新的复合材料，固-液相变转化温度为21℃。First, a certain amount of rosin is heated to melt, then CaCl 2 powder with a mass ratio of CaCl 2 to rosin of 1:50 is poured into the melted rosin, and the mixture is stirred until CaCl 2 is completely dissolved in the rosin. The new composite material finally formed has a solid-liquid phase transition temperature of 21°C.
实施例2Example 2
首先将一定量的松香加热至熔化，然后将CaCl2与松香质量比为1∶45的CaCl2粉末倒入熔化的松香中，对混合物搅拌，直至CaCl2完全熔解于松香之中。最终形成的新的复合材料，固-液相变转化温度为23℃。First, a certain amount of rosin is heated to melt, then CaCl 2 powder with a mass ratio of CaCl 2 to rosin of 1:45 is poured into the melted rosin, and the mixture is stirred until CaCl 2 is completely dissolved in the rosin. The new composite material finally formed has a solid-liquid phase transition temperature of 23°C.
实施例3Example 3
首先将一定量的松香加热至熔化，然后将CaCl2与松香质量比为1∶30的CaCl2粉末倒入熔化的松香中，对混合物搅拌，直至CaCl2完全熔解于松香之中。最终形成的新的复合材料，固-液相变转化温度为29℃。First, a certain amount of rosin is heated to melt, then CaCl 2 powder with a mass ratio of CaCl 2 to rosin of 1:30 is poured into the melted rosin, and the mixture is stirred until CaCl 2 is completely dissolved in the rosin.

在应用时，生产温度应低于材料的相变温度，将固态的松香-CaCl2复合相变蓄能材料加工成颗粒，添加于墙体材料或复合地板中即可。松香-CaCl2复合相变蓄能材料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，从而达到节能和提高环境舒适度的作用。In application, the production temperature should be lower than the phase change temperature of the material, and the solid rosin-CaCl 2 composite phase change energy storage material is processed into granules and added to wall materials or composite floors. The rosin-CaCl 2 composite phase change energy storage material can use the phase change of the material itself to store energy when the ambient temperature exceeds the phase change temperature of the material, and the reverse phase change occurs when the temperature is lower than the phase change temperature of the material to release heat. So as to achieve energy saving and improve environmental comfort.
