Embodiment 1

[0010] First, a certain amount of rosin is heated to melt, and then CaCl 2 The mass ratio of CaCl to rosin is 1:50 2 Pour the powder into the melted rosin and stir the mixture until the CaCl 2 It is completely dissolved in rosin. The new composite material finally formed has a solid-liquid phase transition temperature of 21°C.

Embodiment 2

[0012] First, a certain amount of rosin is heated to melt, and then CaCl 2 The mass ratio of CaCl to rosin is 1:45 2 Pour the powder into the melted rosin and stir the mixture until the CaCl 2 It is completely dissolved in rosin. The new composite material finally formed has a solid-liquid phase transition temperature of 23°C.

Embodiment 3

[0014] First, a certain amount of rosin is heated to melt, and then CaCl 2 CaCl with rosin mass ratio of 1:30 2 Pour the powder into the melted rosin and stir the mixture until the CaCl 2 It is completely dissolved in rosin. The new composite material finally formed has a solid-liquid phase transition temperature of 29°C.

[0015] In application, the production temperature should be lower than the phase transition temperature of the material, and the solid rosin-CaCl 2 The composite phase change energy storage material is processed into granules, which can be added to wall materials or composite floors. Rosin-CaCl 2 The 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 a...

Abstract

This invention discloses a method for manufacturing a rosin-calcium chloride phase change energy-storage composite material, which comprises the steps of: melting rosin, adding calcium chloride powders to molten rosin according to a certain weight ratio, mixing and stirring until calcium chloride is completely molten in rosin to obtain a stable composite material. The said rosin and calcium chloride are both technical grade. The rosin-calcium chloride phase change energy-storage composite material can be added in walls and floors for architecture indoor energy storage. This invention has such advantages as wide raw material resources.

Description

technical field [0001] The present invention relates to a kind of preparation method of building energy-saving material, particularly relate to a kind of rosin-CaCl 2 A manufacturing method of a composite phase change energy storage material. Background technique [0002] 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 it...
