Phase-change and heat-storage heat preservation material and production method thereof

Abstract

The invention relates to a phase-change and heat-storage heat preservation material and a production method thereof. The production method comprises the following steps: mixing paraffin wax, synthetic fatty acid, adipic acid, montan wax, crystal wax of heat storage materials accounting for 60 percent of the total weight in stirring and heating conditions according to a certain weight part ratio; raising the temperature to a certain value in atmospheric pressure; sequentially adding fire retardant, moisture repel, pour point depressant, stain control agent, mildew preventive and cement enhancer of adjustment materials accounting for 40 percent of the total weight under continuously stirring for reaction in a certain time; and keeping the temperature for 3 to 6 hours under continuously stirring, raising the temperature to 300 to 320 DEG C, keeping the temperature for few minutes, coating the materials to be finished goods when the temperature drops to be suitable for coating. The phase-change and heat-storage heat preservation material can become liquid phase so as to store heat energy when being heated (heat sources of sunlight, and the like) to achieve the saturation temperature; and when external temperature is lower than a set temperature, the phase-change and heat-storage material releases the heat energy, the phase-change material becomes solid phase from the liquid phase when the heat energy release is completed, and the process is repeated again and again for cycle.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a phase change thermal storage thermal insulation material and a production method thereof. Background technique [0002] As we all know, the materials used in the existing building walls and the energy-saving and thermal insulation systems for maintaining the walls are relatively simple, especially in northern my country, in order to keep the building walls warm, a layer of 60mm thick benzene board is added, although it can play a certain role. However, there are various problems such as flammability, toxicity, short service life, and complicated construction. At present, it is difficult to achieve the target of 65% energy saving, and its alternative materials are in urgent need of research and development. [0003] In the context of the global financial crisis, the National Development and Reform Commission first proposed energy conservation as the first me...

[0002] As we all know, the materials used in the existing building walls and the energy-saving and thermal insulation systems for maintaining the walls are relatively simple, especially in northern my country, in order to keep the building walls warm, a layer of 60mm thick benzene board is added, although it can play a certain role. Excellent thermal insulation effect, but there are various factors such as flammability, toxicity, short service life, and complicated construction.

At present, it is difficult to achieve the target of 65% energy saving, and its alternative materials are in urgent need of research and development
