Embodiment 1

[0047] A building decorative board with titanium slag extraction, comprising the following components by weight percentage: titanium slag extraction: 35%, light-burned magnesium oxide powder: 25%, magnesium sulfate heptahydrate: 12.5%, active filler: 3%, crops Waste: 5%, modified admixture: 1%, water: 18.5%. Additional materials: glass fiber mesh cloth, non-woven fabric.

[0048] The production method of titanium tailing slag building decoration board comprises the following steps:

[0049] 1) Dissolve magnesium sulfate heptahydrate in water to form MgSO 4 The solution was left to stand for 24 hours for use.

[0050] 2) MgSO 4 The solution, light-burned magnesia powder and modified admixture are added to a stirring device and stirred for 2 minutes, then titanium extraction tailings and active fillers are added and stirred for 4 minutes, and finally crop waste is added and stirred for 3 minutes to obtain a uniformly stirred slurry.

[0051] 3) Lay a layer of glass fiber mes...

Abstract

The invention provides a titanium extraction tailing building decoration plate, which is prepared from the following ingredients in percentage by weight: 35 to 45 percent of titanium extraction tailings, 15 to 25 percent of light calcined magnesia powder, 8 to 15 percent of magnesium sulfate heptahydrate, 1 to 5 percent of active filling materials, 3 to 7 percent of crop wastes, 0.5 to 2 percent of modified additives and 15 to 20 percent of water, wherein additional materials are glass fiber mesh cloth and non-woven fabric. Compared with the prior art, the titanium extraction tailing buildingdecoration plate has the beneficial effects that the industrial waste slag titanium extraction tailings obtained by the PanZhiHua Steel blast furnace slag titanium extraction process and the light calcined magnesia powder prepared from low-grade magnesite, and the magnesium sulfate heptahydrate which is byproduct of boracic acid prepared from ascharite are used as major raw materials; green and environment-friendly effects are achieved; the cost is low; the production process is simple. The addition quantity of the PanZhiHua Steel titanium extraction tailings is great; the ecological environment problem caused by the PanZhiHua Steel titanium extraction tailing stacking storage can be effectively solved; meanwhile, the titanium extraction tailing building decoration plate has the advantagesof high intensity, water resistance, fire resistance, anti-corrosion performance, no deformation, no tilting and the like.

Description

technical field [0001] The invention relates to the field of building materials industry, in particular to a building decoration board for extracting titanium tailings and a production method thereof. Background technique [0002] At present, there is no relevant research on building decorative panels based on the tailings of titanium extracted from Panzhihua Iron and Steel Co., Ltd. Panzhihua Iron and Steel adopts the method of high-temperature carbonization-low-temperature selective boiling chlorination to extract titanium to recover titanium resources in blast furnace slag. After the blast furnace slag is processed by the titanium extraction process, a large amount of titanium extraction tailings will be produced. Panzhihua Iron and Steel is expected to produce hundreds of titanium extraction tailings every year. tons. A large amount of chloride ions remain in the tailings of titanium extraction, so that the tailings of titanium extraction cannot be used as a mixture of ...
