Abstract

The invention discloses a preparation method of a guide rod flame-retardant coating high-performance binder, and belongs to the field of binder technology. The preparation method comprises following steps: step 1, by mass, 1 part of titanium dioxide, 2 to 3 parts of borax, and 4 to 6 parts of silicon carbide are weighted, and are stirred for 20min at room temperature so as to obtain a mixture A; step 2, by mass, 30 to 35 parts of phenolic resin, 8 to 12 parts of furfuryl alcohol resin, 5 to 9 parts of methyl diphenylene diisocyanate, and 10 to 14 parts of urea-formaldehyde resin are weighted, and are stirred for 50min at a temperature of 35 to 40 DEG C so as to obtain a mixture B; step 3, by mass, 0.5 to 1 part of neodymium oxide, 0.3 part of yttrium oxide, and 1 to 1.5 parts of zirconium oxide are weighted, the mixture A is added into the mixture B, then neodymium oxide, yttrium oxide, and zirconium oxide are added, and an obtained material is stirred. Demoulding and curing time is shortened greatly when the high-performance binder is used for producing guide rods, production efficiency is increased, and high-temperature resistance of the guide rods is increased greatly.

Description

technical field [0001] The invention relates to the technical field of bonding agent, in particular to a method for preparing a high-performance bonding agent for guiding rod refractory layers. Background technique [0002] At the end of BOF smelting, all the slag floats on the surface of molten steel. During the tapping process of the BOF, especially after most of the molten steel is discharged, the molten steel will form a strong eddy current at the tapping port, and the slag will inevitably follow the Molten steel flows out. Since slag contains a large amount of harmful components to molten steel, and these harmful components will return or dissolve into molten steel at any time, affecting the purity of molten steel and the quality of the final steel product. At the same time, a large amount of slag will also form different The form consumes the alloy, which reduces the alloy yield in the molten steel refining process. For this reason, iron and steel enterprises at home...
