Formulation process and construction technology of fireproof coating for steel structure

1. Example I of steel structure fireproof coating

20~40 portions of dodecanol fat,

50-60 parts of silica alumina mixture,

5-10 parts of titanium dioxide,

0.5~1 part of ammonium polyphosphate,

5~10 portions of trimethyl phosphate.

Features: The steel structure fire retardant coating of this process can withstand long-term high temperature baking, and has the effect of fire protection and heat insulation. It can prevent the steel from rapidly heating up in the fire and reducing its strength, and prevent the steel structure from losing its support ability and causing the collapse of the building.

2. Example II of steel structure fireproof coating

20~40 parts of water-based resin‘

50-60 parts of silica alumina mixture,

5~10 parts of titanium dioxide, 0.5~1 part of ammonium bichloride,

5~10 portions of trimethyl phosphate.

Features: The steel structure fire retardant coating of this process can withstand long-term high temperature baking, and has the effect of fire protection and heat insulation. It can prevent the steel from rapidly heating up in the fire and reducing its strength, and prevent the steel structure from losing its support ability and causing the collapse of the building.
