Abstract

The invention relates to a building thermal insulation coil containing a phase change material and a preparation method thereof. The thermal insulation coil comprises a thermal insulation base layer, a first reflection layer, a carrier layer, a heat storage layer, and a second reflection layer from the side facing the building to the outside. layer; the heat storage layer contains a phase change material. The thermal insulation coil is obtained by suspension polymerization method to obtain paraffin microcapsules, and the paraffin microcapsules are dispersed in acrylic emulsion to obtain a heat storage material, which is then coated on a carrier material, and then ultrafine copper powder is coated on both sides of the carrier material to obtain The first reflective layer and the second reflective layer are made by bonding the first reflective layer and the thermal insulation material together. The thermal insulation coiled material prepared by the invention is convenient for transportation and construction, has good thermal insulation effect in winter and good thermal insulation effect in summer, and has good air permeability and can keep buildings dry.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation materials, in particular to a building thermal insulation coil containing phase change materials and a preparation method thereof. Background technique [0002] Insulation material is an insulating material with low thermal conductivity, which is used for heat insulation, hindering heat transfer or minimizing heat transfer. Commonly used insulation materials are rock wool or glass wool. Heat transfer is reduced and temperature gradients are maintained through the use of insulating materials. Especially when the temperature fluctuates greatly, for example during day and night, summer and winter, when the thermal energy is too high, cooling is performed, and when the thermal energy is too little, heating is performed. But heating and cooling themselves require energy input and are therefore costly. [0003] Phase change material (PCM, short for phase change material) refers to ...
