Abstract
The present invention relates to a method of producing building energy-saving materials, particularly to a method of producing colophony-calcium chloride phase changing energy accumulating materials. The method is characterized in that colophony is heated until the colophony is melted, a certain proportion of calcium chloride powder is put into the melted colophony, and a mixture is stirred until the calcium chloride powder is completely liquated in the colophony to finally form stable composite materials. The colophony and the calcium chloride are respectively industrial colophony and industrial calcium chloride. The colophony-calcium chloride phase changing energy accumulating materials can be added into a wall body and a floor to be used, be used in indoor energy accumulation and energy saving of construction, and have the advantages of easy material obtainment and low cost.
Description
Technical field
The present invention relates to a kind of making method of energy-saving building materials, particularly relate to a kind of rosin-CaCl
2The making method of composite phase-change energy-accumulation material.
Background technology
The phase-changing energy-storing material of construction is a kind of novel energy-saving building materials that forms by the improvement to traditional building material, it can utilize the phase transformation of material itself to carry out accumulation of energy when envrionment temperature surpasses the transformation temperature of material, reverse phase transformation takes place when temperature is lower than the transformation temperature of material emit heat, realize the self-control of energy, reach the reduction fluctuations in indoor temperature, thereby reach effect energy-conservation and that improve environmental degree of comfort.Phase change material (PCM) is to utilize the heat that absorbs in the phase transition process or discharge to carry out the material of latent heat accumulator, has the ability that changes its physical condition in certain temperature range.The phase-changing energy-storing material of construction is to develop by add phase change material in traditional material of construction.Generally energy storage materials of phase change can add in body of wall, the floor and uses, and is used for architecture indoor energy storage.But there is the general higher shortcoming of price in existing energy storage materials of phase change, can not be used widely and promote.
Summary of the invention
The object of the present invention is to provide that a kind of material is easy to get, the making method of lower-cost colophony-calcium chloride composite phase-change energy-accumulation material.This method is with rosin and CaCl
2Be raw material, by the stirring after the heating the two being uniformly dispersed becomes a kind of new matrix material.The solid-liquid phase change temperature of this matrix material is a kind of very ideal energy storage materials of phase change for building between 20 ℃～35 ℃.
The objective of the invention is to be achieved through the following technical solutions:
The making method of colophony-calcium chloride phase changing energy accumulating material: earlier rosin is heated to fusing, again with CaCl
2With the rosin quality ratio be the CaCl of 1: 50 or 1: 45 or 1: 30
2Powder is poured in the rosin of fusing, mixture is stirred, until CaCl
2Be melted among the rosin fully.
Described rosin-CaCl
2The making method of energy storage materials of phase change, its rosin, CaCl
2Be technical grade rosin, CaCl
2
Advantage of the present invention and effect are:
The present invention is that a kind of material is easy to get, the making method of lower-cost colophony-calcium chloride composite phase-change energy-accumulation material, with rosin and CaCl
2For raw material is a main raw material, raw material obtains easily and is with low cost.

2With the rosin quality ratio be 1: 50 CaCl
2Powder is poured in the rosin of fusing, mixture is stirred, until CaCl
2Be melted among the rosin fully.The final new matrix material that forms, the solid-liquid phase change invert point is 21 ℃.
Embodiment 2
At first a certain amount of rosin is heated to fusing, then with CaCl
2With the rosin quality ratio be 1: 45 CaCl
2Powder is poured in the rosin of fusing, mixture is stirred, until CaCl
2Be melted among the rosin fully.The final new matrix material that forms, the solid-liquid phase change invert point is 23 ℃.
Embodiment 3
At first a certain amount of rosin is heated to fusing, then with CaCl
2With the rosin quality ratio be 1: 30 CaCl
2Powder is poured in the rosin of fusing, mixture is stirred, until CaCl
2Be melted among the rosin fully.The final new matrix material that forms, the solid-liquid phase change invert point is 29 ℃.
When using, the production temperature should be lower than the transformation temperature of material, with solid-state rosin-CaCl
2The composite phase-change energy-accumulation material is processed into particle, makes an addition in materials for wall or the composite floor board to get final product.Rosin-CaCl
2The composite phase-change energy-accumulation material can utilize the phase transformation of material itself to carry out accumulation of energy when envrionment temperature surpasses the transformation temperature of material, reverse phase transformation taking place when temperature is lower than the transformation temperature of material emit heat, thereby reaches effect energy-conservation and that improve environmental degree of comfort.
