Preparing method of modified calcium hydroxide
The invention discloses a preparing method of modified calcium hydroxide. The method comprises the following steps: (1) mixing raw materials; (2) preparing suspension; (3) performing ultrasonic dispersing; (4) heating; (5) performing suction filtration under reduced pressure, and vacuum drying, thus obtaining modified calcium hydroxide particles. The preparing method of the modified calcium hydroxide is simple in process, is simple and convenient to operate, and is environment-friendly as no organic solvent is added; in addition, by adding cyclodextrin, microcosmically, a hydroxyl of the cyclodextrin and the calcium hydroxide form a firm hydrogen bonding, so that the hydroxyl can serve as a good anchoring functional group and form anchoring points at the surfaces of the calcium hydroxide particles, and the cyclodextrin embeds the calcium hydroxide molecules and effectively isolates the reaction between the calcium hydroxide molecules and carbon dioxide; macrocosmically, the sodium hydroxide particles are favorably dispersed and are improved in compatibility in a polymer; in addition, the calcium hydroxide is stable in property and avoids agglomeration.
