Preparation method of nano calcium carbonate for solar photovoltaic adhesive
The invention discloses a preparation method of nano calcium carbonate for solar photovoltaic adhesive, which comprises the following steps: adding cane sugar into lime milk, cooling the lime milk to 6-10 DEG C, and introducing mixed gas with high carbon dioxide concentration for carbonation reaction to obtain 1 # calcium carbonate suspension; adding hot water to dilute the suspension liquid, introducing mixed gas with low carbon dioxide concentration to carry out carbonation reaction, and adding lime milk into the suspension liquid to carry out calcium carbonate reaction to obtain 2 # calcium carbonate suspension liquid; adding sodium stearate into the suspension liquid for surface treatment, adding soluble inorganic metal salt, and finally respectively adding phosphoric triamide and phosphate for surface treatment; and dehydrating by a filter press, drying and crushing to obtain the nano calcium carbonate. The nano calcium carbonate with controllable particle size and more regular morphology is prepared by adopting a unique carbonation process, and the nano calcium carbonate can be endowed with more excellent mechanical properties; through special surface treatment, the aging resistance of the nano calcium carbonate filled photovoltaic adhesive is further improved.
