Phase-change energy-storage dual-limit temperature adjustment mortar and preparation method thereof
The invention discloses phase-change energy-storage dual-limit temperature adjustment mortar and a preparation method thereof. The phase-change energy-storage dual-limit temperature adjustment mortar comprises the following raw materials in parts by weight: 25 parts of cement, 20-55 parts of medium sand, 10-30 parts of phase-change microcapsules, 10-40 parts of expanded perlite shape-stabilized phase-change particles, 0.25-1 part of fibers, 0.2-0.5 parts of cellulose ether, 1.5-3 parts of redispersible latex powder and 25-30 parts of water, wherein the phase-change temperature of the phase-change microcapsules is 18-20 DEG C and the phase-change temperature of the expanded perlite shape-stabilized phase-change particles is 26-28 DEG C. The phase-change energy-storage dual-limit temperature adjustment mortar prepared by the method has a dual-limit temperature adjustment function, not only can remarkably adjust a room temperature to be within upper and lower limit ranges of a comfortable temperature of a human body and improve thermal comfort of a human settlement environment but also improves energy-storage and temperature-adjustment capabilities of a phase-change mortar product and overcomes performance deficiencies existent during addition of a single phase-change medium through compound addition of two phase-change mediums, that is to say, the phase-change microcapsules and the expanded perlite shape-stabilized phase-change particles.
