Abstract

The invention provides a partition board. The partition board comprises 25 to 40 wt% of extraction titanium tailings, 38 to 47 wt% of magnesium oxide, 18 to 24 wt% of magnesium sulfate, 0 to 4 wt% ofcoal ash, 0.4 to 1 wt% of straw fiber, 0.5 to 2 wt% of an additive, and 0.05 to 0.1 wt% of a foaming agent. The partition board is light, high-strength, fireproof and heat-insulating, and has the advantages that chloride ion in the extraction titanium tailings reacts with light calcined magnesia to produce stable cement strength phase (518 phase), and the content of water soluble chloride ion in the extraction titanium tailings is reduced, so that changing waste material into things of value is realized, the problems of land occupation and environmental pollution of the extraction titanium tailings are solved, and the partition board has good economic benefit and social benefit. The invention further provides a preparation method of the partition board.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a partition board and a preparation method thereof. Background technique [0002] In recent years, the country has proposed relevant policies for the construction market to encourage the development of prefabricated sustainable buildings. With the continuous improvement of relevant policy standards, my country's construction industry is transforming towards the modernization of green buildings and the construction industry, making lightweight partition panels The application prospect is more and more extensive. [0003] The blast furnace slag of Panzhihua Iron and Steel Co., Ltd. extracts TiO, a useful component in the slag, through high-temperature carbonization and low-temperature chlorination. 2 After that, a large amount of tailings are produced. This solid waste contains chloride ions and residual carbon, so it cannot be directly used as a concrete admixture. At p...
