Nickel slag-flyash foam glass and preparation method thereof

The invention discloses nickel slag-flyash foam glass and a preparation method thereof. The nickel slag-flyash foam glass is mainly prepared from, by weight, 20-40 parts of nickel slag, 5-20 parts of flyash, 30-50 parts of waste glass, 3-7 parts of foaming agents, 1-5 parts of foam stabilizing agents and 1-5 parts of fluxing agents. Compared with the prior art, the obtained foam glass has the advantages that the higher compressive strength is achieved, the compressive requirements of a product are met, the density is low, and the application range is wide; in addition, the lower heat conductivity coefficient and water absorption are achieved, and the whole performance of the product is excellent. The industrial solid waste is adopted as the source of the used raw materials, not only is the cost reduced, but also the natural resources are saved, and the good economic benefit and environmental protection benefit are achieved.
