Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the following will be combined with specific embodiments and with reference to the appended figure 1 , to further describe the present invention in detail. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0023] A magnesium-calcium fired powdery resin proposed by the present invention has components by weight percentage: 40-50% xylene, 10-20% naphthalene, 10-15% methylnaphthalene, 5-10% dimethylnaphthalene, 15-20% biphenyl, 5-10% bicyclic aromatic hydrocarbons, 2-6% formaldehyde and 30-36% zirconium dioxide.

[0024] In an optional embodiment, the composition by weight percentage is: 40% xylene, 10% naphthalene, 10% me...

Abstract

The invention relates to the technical field of adhesives, and discloses a magnesium-calcium sintered powdery resin which comprises the following components in percentage by weight: 40-50% of xylene,10-20% of naphthalene, 10-15% of methylnaphthalene, 5-10% of dimethylnaphthalene, 15-20% of biphenyl, 5-10% of bicyclic aromatic hydrocarbon, 2-6% of formaldehyde and 30-36% of zirconium dioxide. Theliquid paraffin and zirconium dioxide are added, so that the ion diffusion speed is increased when the sintering temperature is higher, the sintering of a sample is effectively promoted, the physicalproperties of a finished product are greatly improved, the amount of free calcium oxide is reduced, and the hydration resistance of the product is improved; meanwhile, preparation is simple and convenient, the production cost is reduced, and popularization is facilitated.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a method for preparing magnesium-calcium fired powdery resin. Background technique [0002] Magnesia-calcium refractories have the advantages of stable thermodynamic properties, no pollution to molten steel, can capture Al2O3, S, P and other non-ferrous impurities in molten steel, and can effectively prevent oxygenation of molten steel, etc., and are rich in raw materials, so it is generally valued, because free CaO It is easy to hydrate and difficult to sinter, which limits the production and use of magnesia-calcium bricks, especially high-calcium magnesia-calcium bricks. Therefore, it is necessary to take effective measures to promote sintering of magnesia-calcium bricks and increase the density of products. [0003] However, the existing resin binder added to the magnesia-calcium fired brick does not help the sintering performance very well, resulting in low molding strength [0004]...
