Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with example drawings, so that those skilled in the art can better understand the present invention.

[0030] (1) First weigh 1.168g of L-lysine, and dissolve it in a mixed solvent of 139ml of distilled water and 8.7ml of cyclohexane to obtain a mixed solution of lysine.

[0031] (2) Use a syringe to absorb the lysine solution, then place the syringe for absorbing the lysine solution on the syringe pump and fix the needle with the high-pressure generating device.

[0032] (3) Place the beaker containing 5ml of TEOS solution on a constant temperature magnetic stirring device, the temperature of the water bath is 50, 55, 60, 65, 70°C respectively, and the solution can be fully stirred.

[0033] (4) Ground the bottom of the beaker with tin foil to prevent electric shock.

[0034] (5) Set up the syringe pump, the total injection volume of lysine solution is 6.65ml, the flow rate is 3, 5, 7, 9ml / h respec...

Abstract

The invention belongs to the technical field of nano material synthesis, and particularly relates to a preparation method of nano SiO2 particles reinforced and dispersed by an electric field. The method comprises the following steps: preparing a lysine solution, controlling the flow rate of the lysine solution by using an injection pump, atomizing the lysine solution by using a high-voltage powersupply, carrying out water bath heating collection by using a beaker containing a TEOS solution, and finally drying the solution at 60 DEG C to obtain SiO2-n. The application range of the electrostatic spraying process is expanded; meanwhile, the method achieves continuous preparation and has practical significance for industrial production.

Description

technical field [0001] The invention belongs to the technical field of synthesis of nanomaterials, in particular to a kind of electric field strengthened dispersed nano-SiO 2 Granule preparation method. Background technique [0002] Silica is not only a raw material for the manufacture of components for optical instruments and electronic products, but also a good catalyst carrier. SiO 2 -n has wide application prospects in the fields of catalysis, optics, magnetic media and new materials because of its unique properties such as small size effect and surface effect. [0003] Since the beginning of the 20th century, researchers have carried out research on electrohydrodynamic atomization (also known as electrostatic spray). Since the 21st century, electrostatic spray technology has been developed by leaps and bounds due to its advantages of simplicity, controllability and high efficiency, and has been widely used to prepare micro-nano particles. Traditional preparation met...
