Basalt fiber felt

Technical Field

The utility model relates to a fire prevention felt technical field especially relates to a basalt fiber felt.

Background

Suspension bridge, cable-stayed bridge and arch suspension bridge are large span bridge structures which are applied more at present, and the bridge cable system is the main bearing structure of suspension bridge, cable-stayed bridge and arch suspension bridge, also can be said as the 'safe lifeline' of the bridge. Thus, its reliability, durability and adaptability are related to the safe and normal use of the bridge structure. The occurrence of fire is also an important influencing factor affecting the safety of the bridge: for example, a cable is easily deformed by a fire caused by collision of an oil tank truck, a passenger car, a sedan car and the like, and the deformation of the cable of a bridge directly causes the damage of a bearing structure of the cable, further causes the collapse of the structure of the bridge, and finally causes disastrous safety accidents and economic losses. Therefore, protection against fire performance is necessary for cable protection.

The basalt fiber is a very popular light building section in China at present, plays an important role in deformation resistance, aging resistance and fire resistance in building engineering, and has the following main application fields: winding to prepare various high temperature, ultralow temperature, chemical corrosion and high pressure resistant pipelines, storage tanks, gas cylinders and the like; repairing and reinforcing the building; can also be used as bulletproof protection materials, fireproof material cloth and the like; at present, the conventional fireproof material cloth is mainly characterized in that a layer of high-temperature-resistant coating is coated on the surface of basalt fiber cloth to improve the fireproof performance of the basalt fiber cloth, but the conventional fireproof material cloth can only meet the requirements of no deformation and no explosion at the temperature of 1000 ℃; and when the basalt fibers are subjected to high temperature, the basalt fibers are easy to pulverize, and the generated smoke dust generates stimulation damage to human bodies.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a basalt fiber felt, basalt fiber felt can the temperature resistant more than 1400 ℃.
