Abstract

The invention discloses a high-performance binder of guide rod flame-retardant coating, and belongs to the field of binding agent technology. The high-performance binder of guide rod flame-retardant coating is prepared from following ingredients, 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, 10 to 14 parts of urea-formaldehyde resin, 1 part of titanium dioxide, 2 to 3 parts of borax, 4 to 6 parts of silicon carbide, 0.5 to 1 part of neodymium oxide, 0.3 part of yttrium oxide, and 1 to 1.5 parts of zirconium oxide. According to the high-performance binder, phenolic resin, furfuryl alcohol resin, methyl diphenylene diisocyanate, and urea-formaldehyde resin are combined, and titanium dioxide, borax, and silicon carbide are added as additives, so that demoulding and curing time is shortened greatly when the high-performance binder is used for producing guide rods, curing period of demoulding ranges from 20 to 40min, 10 to 12 hours of curing after demoulding is enough, 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 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 and abroad have adopte...
