Embodiment 1

[0028] Add 0.60g of zirconium dioxide, 0.13g of waste polyethylene and 1.20g of metal lithium into a 20ml stainless steel autoclave, seal it and put it into an electric furnace capable of temperature-programming, and the furnace temperature rises from room temperature to 700°C, then maintained at 700°C for 10 hours and then cooled to room temperature naturally. The final product in the autoclave consisted of black deposits and residual gas. Collect the black deposits stuck on the inner surface of the kettle wall, wash with distilled water, dilute hydrochloric acid and absolute ethanol several times, obtain samples after filtration, and dry the samples in a vacuum drying oven at 50°C for 4 hours, and finally collect them for use in representation.

[0029] The phase analysis of the powder was carried out by a Japanese Rigaku D / max-γA X-ray powder diffraction (XRD) instrument, Cu Graphite monochromator, the tube voltage and current are 40kV and 40mA, respectively, and the sca...

Embodiment 2

[0032] Add 0.60g of zirconium dioxide, 0.35g of waste polyvinyl chloride and 1.20g of metal lithium into a 20ml stainless steel autoclave, seal it and put it into an electric furnace capable of temperature programming, and the furnace temperature will rise from room temperature within 68 minutes. to 700°C, then maintained at 700°C for 10 hours and then cooled to room temperature naturally. The final product in the autoclave consisted of black deposits and residual gas. Collect the black deposits stuck on the inner surface of the kettle wall, wash with distilled water, dilute hydrochloric acid and absolute ethanol several times, obtain samples after filtration, and dry the samples in a vacuum drying oven at 50°C for 4 hours, and finally collect them for use in representation.

Embodiment 3

[0035] Add 0.60g of zirconium dioxide, 0.30g of waste polytetrafluoroethylene and 1.20g of metal lithium into a 20ml stainless steel autoclave. Raised to 700°C, then maintained at 700°C for 40 hours and then cooled to room temperature naturally. The final product in the autoclave consisted of a black deposit. Collect the black deposits stuck on the inner surface of the kettle wall, wash with distilled water, dilute hydrochloric acid and absolute ethanol several times, obtain samples after filtration, and dry the samples in a vacuum drying oven at 50°C for 4 hours, and finally collect them for use in representation.

Abstract

The invention belongs to the technical field of zirconium carbide nanomaterials and particularly relates to a method of preparing a zirconium carbide nanomaterial with waste plastics. The method comprises the steps of (1) adding zirconium dioxide, waste plastics and metallic lithium into a reactor in a mass ratio of 1:(0.2-1):(2-10); (2) heating the reactor to allow chemical reaction to occur, andcooling after the reaction is over; (3) washing the product, and drying to obtain the zirconium carbide nanomaterial. The waste plastics are used as carbon sources herein; the material origin range is wide; the materials are low in price; conversion of the waste plastics to the zirconium carbide nanomaterial can be achieved herein through one-step chemical reaction; the environmental pollution problem due to waste plastics is solved.

Description

technical field [0001] The invention belongs to the technical field of zirconium carbide nanomaterials, in particular to a method for preparing zirconium carbide nanomaterials from waste plastics. Background technique [0002] As an ultra-high temperature ceramic material, zirconium carbide has excellent physical and chemical properties, such as high hardness, high melting point, high wear resistance, low vapor pressure, low resistivity, good chemical stability and thermal stability. [0003] At present, the method for preparing zirconium carbide is mainly to use zirconium dioxide and carbon reaction reduction synthesis method (J.Mater.Sci., 2004,39,6057-6066.), sol-gel method (J.Eur.Ceram.Soc ., 2007, 27, 2061-2067.) and chemical vapor deposition (Appl. Surf. Sci., 2015, 332, 591-598, Surf. Coat. Technol., 2008, 203, 87-90.) method. [0004] The industrial preparation of zirconium carbide is mainly by carbothermal reduction of zirconium dioxide (ZrO 2 ), but carbon reduct...
