Embodiment 1
[0017] 1.1 Preparation of flame-retardant and corrosion-resistant alloys
[0018] (1) Weigh according to mass percentage: 20% magnesium, 10% titanium, 15% lithium, 5% cobalt, 10% nickel, 4% vanadium, conduct vacuum medium frequency induction melting, cast ingot, and grind into nano-alloy powder;
[0019] (2) Mix the prepared nano-alloy powder with 25% polypropylene, 2% calcium stearate, and 9% wollastonite. The melt flow rate of the polypropylene is 50g / min. Stir at a speed of 80 rpm, and obtain a nano-alloy powder-polypropylene mixed solution in 50 minutes;
[0020] (3) After homogenizing the ingot of the above mixed solution, melt, mix and disperse it in a twin-screw extruder with a length-to-diameter ratio of 60:1, and extrude alloys of different shapes according to requirements. The melting and mixing temperature is 200 ℃.
