Abstract

The invention discloses a novel energy-saving and environment-friendly phase-change energy storage wall panel and a preparation method thereof. The structure of the wall panel consists of hydrophobic and moisture-proof non-woven fabric, water-blocking adhesive film, and phase-change GMT core from the wall surface to the outside. layer, hot-melt adhesive film, adhesive non-woven fabric, hot-melt adhesive layer and decorative fabric layer, wherein the phase-change GMT core layer contains at least two or more composite phase-change energy storage materials. The invention adjusts the ratio of phase change energy storage materials with different phase transition temperatures according to local conditions, and evenly adds them to the wall panel, so that it can adapt to the climate difference between the north and the south and the temperature difference between winter and summer, and intelligently control the indoor temperature, so as to achieve high efficiency. energy saving and environmental protection functions.

Description

technical field [0001] The invention relates to the field of GMT wallboard manufacturing, in particular to a novel energy-saving and environment-friendly phase-change energy storage wallboard and a preparation method thereof. Background technique [0002] Wall panels are functional building materials used to protect walls and integrate decoration, temperature insulation and noise reduction. With the continuous improvement of people's living standards, technical indicators such as "health and environmental protection", "energy saving and emission reduction", "sound absorption and heat insulation" are more and more respected by people, requiring material manufacturers to continue to improve and innovate. [0003] The clapboard plays the role of sound insulation and heat preservation indoors, but the indoor temperature will become extremely high under high temperature baking in summer, which can reach above 35°C. In winter, under severe cold conditions, the indoor temperature c...
