preparation example 1
[0042] S1, first use deionized water to cook the steel slag for 2h, then remove the steel slag from the deionized water and drain it, so as to obtain the cooking steel slag;
[0043] S2. First melt 30kg of thermoplastic, add 2kg of nano-silicon carbide powder and stir evenly, then place 80kg of cooking slag in the molten thermoplastic and soak for 1 hour, remove the cooking slag from the molten thermoplastic and cool it to room temperature to obtain a modified Steel slag.
preparation example 2
[0045] S1, first use deionized water to cook the steel slag for 2h, then remove the steel slag from the deionized water and drain it, so as to obtain the cooking steel slag;
[0046] S2, first melt 20kg of thermoplastic, add 2kg of nano-silicon carbide powder and stir evenly, then place 100kg of cooking slag in the molten thermoplastic and soak for 1 hour, remove the cooking slag from the molten thermoplastic and cool to room temperature to obtain a modified Steel slag.
