Embodiment Construction
[0015] A composite slag thermal insulation wall material for reusing waste plastics, made of the following raw materials in parts by weight: blast furnace slag 80, modified expandable waste plastic particles 10, iron tailings 20, bauxite slag 5, lithium slag 3.5. Ordinary Portland cement10.
[0016] Among them, the modified expandable waste plastic particles are mixed with 1% sodium silicate and an appropriate amount of water, and then sent to the autoclave, and butane is added as a foaming agent, so that the foaming temperature: 65 ℃ , Saturation pressure: 0.5MPa, Saturation time: 1h The dry particles obtained by passing through the blowing agent and foaming.
[0017] The preparation method of the thermal insulation wall material of this embodiment comprises the following steps:
[0018] (1) The blast furnace slag, bauxite slag, lithium slag, and iron tailings are crushed and ground respectively, and passed through a 100-mesh sieve;
[0019] (2) Mix the powder prepared in s...
