Abstract

The present application discloses an environment-friendly phase change gypsum board. The phase change gypsum board includes gypsum and a phase change microcapsule material, and the phase change microcapsule material includes a core material and an inorganic wall material wrapping the core material, wherein the core material is phase change paraffin, and the inorganic wall material is any one or more selected from the group consisting of SiO2, TiO2 and CaSiO3. According to the phase change gypsum board provided by the present application, the inorganic wall material is used to wrap the core material, no organic matter is released during use, so that the purpose of environmental protection is realized; and at the same time, a composite reinforcing agent is used to enhance the strength of thegypsum board.

Description

Technical field [0001] The present application relates not limited to the field of building materials, and more particularly, but is not limited to, an environmentally friendly phase change gypsum board and a preparation method thereof. Background technique [0002] The phase transition energy storage material is a type of material that absorbs or releases phase change in the transition of the substance, thereby achieving a type of material that is energy stored and released. Phase transition energy storage materials in modern agricultural greenhouses, solar utilization, biomedicine products and food refrigeration and transportation, physical medical (thermal), electronic equipment cooling, athletes cooling (warm) clothing, special controlled clothing, aerospace technology, military Infrared camouflage, power peak applications, industrial waste heat storage and utilization have application prospects. [0003] According to the phase change temperature, the phase change energy stor...
