Graphite slag light partition board and preparation method thereof

Abstract

The invention discloses a graphite slag light partition board and a preparation method thereof. The preparation raw materials of the graphite slag light partition board comprise a dry material and water, and the dry material is prepared from the following components by mass: 50-70 parts of graphite tailings, 20-25 parts of steel slag powder, 20-30 parts of cement, 15-25 parts of fly ash, 0.02-0.05part of a drag reducer and 0.08-0.1 part of a water-resistant enhancer. The industrial solid waste is used as the raw material, the graphite slag and the steel slag powder are used as the raw materials to prepare the light partition board, the potential volcanic ash effect of the steel slag powder is fully used for replacing part of cement, the production cost is reduced, the hydration heat of the cement can be reduced, and the later strength of concrete products is improved; the light partition board is high in compressive strength, has the characteristics of light weight, heat preservation,sound insulation, fire prevention, light weight, convenient installation and the like, belongs to recycling of industrial solid wastes, turns waste into wealth, not only saves increasingly scarce energy resources, but also protects the living environment.

Description

technical field [0001] The invention relates to the technical field of lightweight partition boards, in particular to a graphite slag lightweight partition board and a preparation method thereof. Background technique [0002] my country is a major producer of graphite and graphene. There are many production enterprises in Shandong, Heilongjiang, Hubei, Sichuan and other provinces, which discharge tens of millions of tons of graphite tailings every year. In recent decades, no large-scale use of graphite tailings has been found. slag development products, the transformation and use of graphite tailings can only be built and stockpiled. This method not only occupies the land resources around the graphite factory, but also causes serious damage to the urban and rural environments. How to convert ecological resources into ecological value? It is also the problem to be solved by this patented technology; the invention patent CN106673554B "a kind of waste light partition board and it...

[0002] my country is a major producer of graphite and graphene. There are many production enterprises in Shandong, Heilongjiang, Hubei, Sichuan and other provinces, which discharge tens of millions of tons of graphite tailings every year. In recent decades, no large-scale use of graphite tailings has been found. slag development products, the transformation and use of graphite tailings can only be built and stockpiled. This method not only occupies the land resources around the graphite factory, but also causes serious damage to the urban and rural environments. How to convert ecological resources into ecological value? It is also the problem to be solved by this patented technology; the invention patent CN106673554B "a kind of waste light partition board and its preparation method" proposed by Han Jiaxing et al. In the method of producing lightweight partition boards by using them, the two patents respectively focus on the use of bulk industrial solid waste to prepare lightweight partition boards by steam curing, mold filling, etc.
