NOVELTY - Sepiolite-zeolite powder doped capric acid phase change microcapsule temperature and humidity control material comprises 260-280 pts. wt. P.O42.5 cement, 0-525 pts. wt. sepiolite, 525-1050 pts. wt. zeolite powder and 0-198 pts. wt. capric acid phase change microcapsule. The water and gelling material weight ratio of the temperature and humidity control material is 0.3-0.4. The gelling material is P.O42.5 cement, sepiolite and zeolite powder. USE - Used as sepiolite-zeolite powder doped capric acid phase change microcapsule temperature and humidity control material. ADVANTAGE - The temperature and humidity control material uses graphene oxide modified urea-formaldehyde resin, which can improve the thermal stability and heat conductivity of capric acid phase change microcapsule, improving the heat transfer efficiency of capric acid phase change microcapsule, and dopes it to sepiolite-zeolite powder matrix, so that the capric acid phase change microcapsule can be embedded in the sepiolite-zeolite powder matrix, so that the passive temperature and humidity control material has good temperature and humidity control performance, improving the comfort of the living environment and reducing the building energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the temperature and humidity control material comprising preparing capric acid phase change microcapsule by mixing formaldehyde solution, urea, graphene oxide and deionized water, adding into a round bottom flask, dropping triethanolamine to adjust the pH at 8-9, and reacting at 60-70 degrees C and 400-500 revolutions/minute (rpm) for 40-60 minutes to form stable prepolymer solution; adding capric acid and composite emulsifier into the three-mouth flask, emulsifying for 60-80 minutes at 1400 rpm and 60-70 degrees C, so as to form stable capric acid emulsion, adjusting the rotating speed at 500-600 rpm, slowly dripping the obtained prepolymer solution into the capric acid emulsion, slowly adjusting the pH of the system at 2-3 by citric acid, acidifying for 60 minutes, raising the temperature to 70-80 degrees C, adding curing agent to solidify, keeping the temperature and reacting for 1.5-2.0 hours, using 10 mass% sodium hydroxide solution to adjust the pH of the system to neutral, continuously reacting for 10 minutes, filtering the obtained product, using deionized water to wash, putting into oven and drying to obtain capric acid phase change microcapsule; and preparing sepiolite-zeolite powder doped capric acid phase change microcapsule temperature and humidity control material by putting the sepiolite and zeolite powder in 105 degrees C vacuum drying box for 1 day to obtain dry sample, taking P.O42.5 cement, capric acid phase change microcapsule, dried sepiolite and dry zeolite powder, adding cement, sepiolite and zeolite powder into a stirring pot for pre-mixing, adding the capric acid phase change microcapsule to pre-mix, adding water, stirring, and obtaining sepiolite-zeolite powder matrix material, pouring the stirred sepiolite-zeolite powder matrix material into 20 mmx 20 mmx 20 mm test mold, and standard curing for 28 days.
