Abstract

The application discloses a phase-change gypsum board with temperature control performance. Based on 100 parts by weight of plaster, the original solution of phase-change microcapsules accounts for 20-80 parts by weight, the binder accounts for 0.5-2.5 parts by weight, the strengthening agent 0.05-0.5 parts by weight, 0.05-1 parts by weight of water reducer, 0.05-1 parts by weight of surfactant, 65-90 parts by weight of water, and 2-10 parts by weight of protective paper. The present application also provides the preparation method of the gypsum board with temperature control performance, comprising: fully mixing plaster of paris, binder, and reinforcing agent to form a dry powder; mixing a water reducer, a surfactant and water to form a wet powder. material; the dry powder material, the phase change microcapsule solution and the wet material are fully mixed to form a slurry; the slurry is placed in the middle of the protective paper, cut and dried to form the phase change gypsum plate. The temperature of the phase-change gypsum board with temperature control performance prepared by the present application has a small fluctuation range 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 ...
