Embodiment 1
[0015] (1) Accurately measure 60ml of ethanol, 30ml of propylene glycol, 25ml of distilled water, weigh 4.0g of emulsifier OP-10, weigh 1.6g of sodium stearate, and 15ml of calcium chloride solution with a concentration of 1M. In a 250ml three-neck flask, stir to form a transparent solution. Make sodium carbonate into an aqueous solution with a concentration of 1M, accurately pipette 15.15ml of sodium carbonate solution, slowly add it dropwise into a three-necked flask, and stir while adding dropwise. -1h to obtain active nano-calcium carbonate dispersion emulsion. The average particle size of the nano-calcium carbonate determined by the light scattering method is 40-60nm, and the crystal form of the nano-calcium carbonate is cubic when observed by a transmission electron microscope.
[0016] (2) Weigh 40g of polyethylene glycol with an average molecular weight of 2000, 4.0g of emulsifier OP-10, 1.0g of emulsifier Textol 1310, measure 80ml of distilled water, add it into a 25...
Embodiment 2
[0020] (1) Accurately measure 70ml of absolute ethanol, 10ml of ethylene glycol, weigh 5 g of polyethylene glycol (average molecular weight 1000) aqueous solution with a concentration of 2% by mass, 1.5g of emulsifier AEO3, 4.0g of emulsifier Textol 1310, 7.5g oleic acid, 30ml calcium chloride solution with a concentration of 1M, add it into a 250ml three-neck flask with a stirring reflux device, and stir to form a transparent solution. Make sodium carbonate into an aqueous solution with a concentration of 1M, accurately pipette 30.5ml of sodium carbonate solution, slowly add it dropwise into a three-necked flask, and stir while adding dropwise. -3.0h to obtain active nano-calcium carbonate dispersion emulsion. The average particle size of the nano-calcium carbonate determined by the light scattering method is 40-60nm, and the crystal form of the nano-calcium carbonate is cubic when observed by a transmission electron microscope.

Embodiment 3
[0024] (1) Accurately measure 17ml of absolute ethanol, 10g of polyethylene glycol (average molecular weight 1000) aqueous solution with a concentration of 3% by mass, weigh 2.0g of emulsifier TW60, 0.5g of emulsifier TW80, weigh Take 6.25g of stearic acid and 52.63ml of calcium chloride solution with a concentration of 2.5M, add them into a 250ml three-necked flask with a stirring reflux device, and stir to form a transparent solution. Make sodium carbonate into an aqueous solution with a concentration of 2.5M, accurately pipette 50.5ml of sodium carbonate solution, slowly add it dropwise into a three-necked flask, and stir while adding dropwise. 0.5h to obtain active nano-calcium carbonate dispersion emulsion. The average particle size of the nano-calcium carbonate determined by the light scattering method is 40-60nm, and the crystal form of the nano-calcium carbonate is cubic when observed by a transmission electron microscope.
