[0019] (1) Weigh 1 g of waste fluorescent powder (red powder 50wt.%, green powder 35wt.%, blue powder 15wt.%), and keep it in a drying oven at 100° C. for 24 hours.

[0020] (2) Weigh 999g of pure magnesium (the composition is 0.005wt.% Al, 0.001wt.% Zn, 0.01wt.% Mn, 0.01wt.% Si, and the balance is Mg), put it into a graphite crucible for heating and melting to liquid state, when the temperature of the melt rises to about 660°C (the superheat of the melt is 10°C at this time), take out the phosphor powder treated in step (1), add it to the melt, and stir with a stirring blade at a speed of 1500rpm After 5 minutes of the melt in the molten state, the temperature of the melt was heated to about 700° C., the slag on the surface of the melt was scooped out, and cast into a sand mold to obtain a waste ph...

Embodiment 2

[0023] In this embodiment, the process of preparing waste fluorescent powder reinforced Mg-Al-Zn-based composite material is carried out according to the following steps:

[0024] (1) Weigh 10 g of waste fluorescent powder (red powder 55wt.%, green powder 40wt.%, blue powder 5wt.%), and keep it in a drying oven at 200° C. for 12 hours.

[0025] (2) Weigh 990g of AZ31 alloy (composition is 3.0wt.%Al, 0.8wt.%Zn, 0.15wt.%Mn, the balance is Mg), put it into graphite crucible and heat and melt to liquid state, wait for the melt The temperature rises to about 650°C (at this time, the superheat of the melt is 20°C), take out the phosphor powder treated in step (1), add it to the melt, and stir the molten melt with a stirring blade at a speed of 1500rpm for 10 minutes , heating the temperature of the melt to 680° C., scooping up the slag on the surface of the melt, and casting it in a metal mold to obtain a waste phosphor powder-reinforced magnesium-based composite material with a pho...

Embodiment 3

[0028] In this embodiment, the process of preparing waste fluorescent powder reinforced pure aluminum matrix composite material is carried out according to the following steps:

[0029] (1) Weigh 50 g of waste fluorescent powder (red powder 55wt.%, green powder 40wt.%, blue powder 5wt.%), and keep it in an oven at 200° C. for 12 hours.

[0030] (2) Weigh 950g of pure aluminum (the composition is 1.1wt.% Mg, 0.62wt.% Si, 0.65wt.% Fe, 0.29wt.% Cu, 0.13wt.% Mn, 0.22wt.% Zn, 0.10wt. %Cr, 0.15wt.%Ti, and the balance is Al), put it into a graphite crucible and heat and melt it to a liquid state, and when the temperature of the melt rises to about 810°C (at this time, the degree of superheat of the melt is 150°C), take out the step (1) After the phosphor powder is processed, add it to the melt, stir the molten melt with a stirring paddle at a speed of 1000rpm for 15 minutes, wait until the temperature of the melt drops to 700°C, scoop out the slag on the surface of the melt, and cast...

Abstract

The invention discloses a magnesium and aluminum metal-matrix composite material enhanced through waste fluorescent powder and a preparation method of the magnesium and aluminum metal-matrix composite material enhanced through the waste fluorescent powder and belongs to the technical field of recycling of the waste fluorescent powder and preparing of metal-matrix composite materials. The preparation method comprises the steps that the waste fluorescent powder is placed in a drying box or an oven to be pretreated; and pure metal or alloy is placed in a crucible to be molten to be in liquid state, melt is heated, a certain amount of pretreated waste fluorescent powder is added into the melt, the melt is stirred for a period of time by means of a stirring device, the melt is poured in a metal die or a sand die after dross on the surface layer of the melt is removed, and then the magnesium and aluminum metal-matrix composite material enhanced through the waste fluorescent powder is obtained. The magnesium and aluminum metal-matrix composite material enhanced through the waste fluorescent powder and the preparation method of the magnesium and aluminum metal-matrix composite material enhanced through the waste fluorescent powder have the advantages that the preparation method of the composite material is easy and convenient to implement, particles are evenly dispersed, the composite material is well bonded with a matrix interface, environmental friendliness is achieved, and cost is low.

Description

Technical field: [0001] The invention relates to a waste fluorescent powder reinforced magnesium and aluminum metal-based composite material and a preparation method thereof, and belongs to the technical field of waste fluorescent powder recycling and metal-based composite material preparation. Background technique: [0002] Rare earths are known as "industrial vitamins" and have become extremely important strategic resources. Rare earth element oxides refer to oxides of 15 lanthanide elements with atomic numbers from 57 to 71 in the periodic table of elements, and oxides of scandium (Sc) and yttrium (Y), which are chemically similar to lanthanide elements, a total of 17 elements. . Rare earth oxides have the characteristics of high hardness and high stability, which can significantly improve the mechanical properties such as strength and hardness of materials, so they are considered as ideal reinforcing phases for ceramics, polymers and metal matrix composites. [0003] A...
