Abstract

The invention discloses a phase change gypsum board with temperature control performance. The phase change gypsum board comprises, on the basis of 100 parts by weight of calcined gypsum, 20-80 parts by weight of a phase-change microcapsule stock solution, 0.5-1.5 parts by weight of a binder, 0.05-0.5 part by weight of a reinforcing agent, 0.05-2 part by weight of a coagulant, 0.05-1 part by weightof a surfactant, 65-90 parts by weight of water and 2-10 parts by weight of surface protection paper. The invention further provides a preparation method of the gypsum board with the temperature control performance. The preparation method comprises the following steps: fully mixing the calcined gypsum, the binder, the reinforcing agent and the coagulant to form dry powder; mixing the water reducing agent, the surfactant and the water to form a wet material; fully mixing the dry powder, the phase change microcapsule solution and the wet material to form slurry; and placing the slurry at the middle part of the surface protection paper, and carrying out cutting and drying to form the phase change gypsum board. The phase change gypsum board with the temperature control performance prepared bythe invention is small in the range of temperature fluctuation along with time.

Description

technical field [0001] The application relates to the field of building materials, in particular to a phase-change gypsum board with temperature control performance and a preparation method thereof. Background technique [0002] According to a survey by the International Energy Agency, in the past 20 years, primary energy consumption has increased by 49%, and CO2 emissions account for about 43%. Moreover, 30% to 40% of energy consumption is building energy consumption. Thermal energy storage materials are considered to be a way to coordinate energy consumption and energy supply balance. Applying phase change energy storage materials to building materials and rational use can reduce Building energy consumption, therefore, phase change energy storage building materials are research hotspots. Patent CN201410176349.0 pointed out that the building energy-saving heat preservation method and the preparation scheme of hollow blocks, the phase change material is directly mixed with ...
