Problems solved by technology

Traditional magnesia binders simply use the hydration reaction between light-burned magnesia and water to generate magnesium hydroxide and form the bonding strength. Only flaky magnesium hydroxide can be produced under this condition, and the strength of the sample is the lowest when the bonded phase is flaky, which is 52.32MPa
Therefore, it is impossible to effectively form a mosaic structure inside the material to meet the actual use requirements.

Embodiment 1-6

[0026] In this embodiment, a corundum castable refractory material is used, and a magnesia binder is used as a binder. The composition of raw materials is shown in Table 1.

[0027] Table 1 raw material ratio composition

[0028]

[0029] Weigh by raw material proportion shown in Table 1, proportioning total weight is 1000g. Put the above raw materials into a mixer and stir evenly, then add 70g of water, continue stirring for 10 minutes to form a slurry, and then inject the slurry into a mold for molding. After forming, the mold is naturally cured for 24 hours, and then the mold is demoulded. After demoulding, the natural curing is continued for 24 hours, and then baked in an oven at 200 ° C for 24 hours. After drying, the compressive strength of the sample was measured according to GB / T5072-2008 "Test Method for Compressive Strength at Normal Temperature of Refractory Materials", and the microstructure of the bonded phase of the sample section was observed with an electr...

Abstract

The invention provides a magnesium binding agent and a method for preparing a refractory material by using the magnesium binding agent. Magnesium oxide, magnesium oleate and methylmalonic acid are used as binding agent components. 0.10-0.15% of magnesium oleate and methylmalonic acid are added, and the ratio of magnesium oleate to methylmalonic acid is set to be 1 / 1 to 2 / 1, so that the microstructure of magnesium hydroxide generated in hydration reaction of magnesium oxide is controlled. Meanwhile, through the implementation process of preparing the refractory material by using the magnesian binding agent, the magnesian binding agent forms an embedded structure in the refractory material, so that the strength of a binding phase of the magnesian binding agent and the refractory material isgreatly improved, the microstructure of a magnesium binding agent added sample is conical, and the compressive strength of the magnesium binding agent added sample can reach 60-70 MPa. The magnesium binding agent and the using method thereof are simple, and the preparation cost is low.

Description

technical field [0001] The invention relates to the technical field of refractories and their preparation, in particular to a magnesia binder and a method for preparing refractories using the magnesia binder, which can be used to improve the bonding strength between the magnesia binder and the refractories. Background technique [0002] Magnesium oxide is widely used as a binder in the fields of refractory materials, structural ceramics and building materials. The strength of the magnesia binder is mainly formed by the hydration reaction of magnesia to form the magnesium hydroxide phase, and the strength of the magnesia binder depends on the microstructure after the hydration process of magnesia in the preparation process. Traditional magnesia binders simply use the hydration reaction between light-burned magnesia and water to generate magnesium hydroxide and form the bonding strength. Only flaky magnesium hydroxide can be produced under this condition, and the strength of ...
