Embodiment 1

[0048] The first step, the treatment of tourmaline:

[0049] According to the mass ratio of tourmaline: deionized water: polyacrylate grinding aid = 1: 2: 0.005, take the required amount of tourmaline, deionized water and polyethyl acrylate grinding aid in the ball mill Carry out wet ball milling at a speed of 700r / min for 1 hour, the ball-to-material ratio is 1:2, then wash the product of wet ball milling with deionized water, and dry it at 60°C for 12 hours to make powdered tourmaline. Roast the dried powdered tourmaline at a temperature of 500°C for 3 hours, cool to room temperature, complete the treatment of tourmaline, and set aside;

[0050] The second step, the preparation of reactant raw material mixture:

[0051] Weigh 1mmol of ammonium molybdate, 10mmol of thioacetamide and 0.1g of the tourmaline treated in the first step, first dissolve the weighed ammonium molybdate in 35mL of deionized water, and stir until the ammonium molybdate is completely Dissolve, then dis...

Embodiment 2

[0057] Except that grinding aid is polymethyl acrylate PMA, other are the same as embodiment 1.

Embodiment 3

[0059] The first step, the treatment of tourmaline:

[0060] Tourmaline by mass ratio: deionized water: polyacrylate grinding aid = 1: 11: 0.025, take the required amount of tourmaline, deionized water and sodium polyacrylate grinding aid, in the ball mill Wet ball milling was carried out at a speed of 1000r / min for 3 hours, the ball-to-material ratio was 1:4, and then the wet ball milled product was washed with deionized water, dried at 70°C for 18 hours, and powdered tourmaline was made. The above dried powdered tourmaline is roasted at a temperature of 700° C. for 6 hours, cooled to room temperature, and the treatment of the tourmaline is completed, ready for use;

[0061] The second step, the preparation of reactant raw material mixture:

[0062] Take by weighing 10mmol of magnesium molybdate, 80mmol of thiourea and 2.5g of tourmaline after the first step treatment, first dissolve the weighed magnesium molybdate in 100mL of deionized water, and stir until the magnesium moly...

Abstract

The invention provides a preparation method of a molybdenum disulfide-tourmaline composite material and relates to a composite material. The molybdenum disulfide-tourmaline composite material is prepared by a microwave hydrothermal method. The preparation method comprises the following steps: treating tourmaline, preparing a reactant raw material mixed liquid of molybdate, sulfide and tourmaline;pouring the reactant raw material mixed liquid into a polytetrafluoroethylene reaction kettle, placing the polytetrafluoroethylene reaction kettle into microwave hydrothermal equipment and completingmicrowave hydrothermal effective composition of the reactants; and washing and drying the product obtained by the microwave hydrothermal method to prepare the molybdenum disulfide-tourmaline compositematerial. The defects in the prior art for preparing the molybdenum disulfide composite material that the molybdenum disulfide composite material is liable to gather or stack again in the drying or annealing process as well as the defects of complex preparation process, long reaction cycle, high energy consumption and high cost are overcome.

Description

technical field [0001] The technical proposal of the invention relates to composite materials, specifically a method for preparing molybdenum disulfide-tourmaline composite materials. Background technique [0002] Molybdenum disulfide is a typical layered transition metal sulfide. Every two layers of sulfur atoms sandwich a layer of molybdenum atoms, forming a typical sandwich structure. The molybdenum atom and the sulfur atom are covalently bonded, adjacent The two molecular layers are connected by relatively weak van der Waals force, and the intralayer interaction is strong while the interlayer interaction is relatively weak. Due to this special layered structure, molybdenum disulfide has good catalytic, lubricating and photoelectric properties, and is widely used in lithium ion battery electrodes and photocatalysis, solid lubrication, sensors, and field effect transistors. [0003] Molybdenum disulfide has high reactivity due to the unsaturation at the edge of its struct...
