Abstract

The invention discloses a nickel slag fly ash foam glass and a preparation method thereof. The nickel slag fly ash foam glass is mainly made of the following raw materials in parts by weight: 20 to 40 parts of nickel slag, 5 parts of fly ash ~20 parts, waste glass 30~50 parts, foaming agent 3~7 parts, foam stabilizer 1~5 parts, fluxing agent 1~5 parts. Compared with the prior art, the foam glass obtained in the present invention has higher compressive strength, can meet the compressive requirements of the product, and has low density and wide application range; in addition, it also has lower thermal conductivity and water absorption rate, and the product The overall performance is excellent. The source of the raw materials used is industrial solid waste, which not only reduces the cost, but also saves natural resources, and has good economic and environmental benefits.

Description

technical field [0001] The invention relates to nickel slag fly ash foam glass and a preparation method thereof, belonging to the technical field of foam glass. Background technique [0002] Nickel slag is a solid waste discharged during the production of non-ferrous metal nickel, which contains SiO 2 , MgO, FeO, Al 2 o 3 , CaO, etc. At present, my country's annual output of nickel smelting slag is more than 2 million tons, most of which are stored in the open air, which not only increases the maintenance cost of the enterprise, but also destroys the local environment and ecological resources; comprehensively utilizes it and makes it waste Being treasure is a requirement of sustainable development. The utilization of nickel slag is mainly in cement concrete and wall materials. Patent "a nickel slag concrete" (201410250898.8), "a wear-resistant concrete mixed with nickel slag" (201410837489.8), a nickel slag brick and its preparation method (201310230070.1), etc.; these m...
