Light Rigid Fire Blockers

Fire barrier play an increasing role in fire prevention and fire fighting. They are useful in modem building industry as well as in different transport areas. They limit not only the fire loses and costs but what's the most important the victims of the fire. The role of fire barriers is specially important in case of transportation. Economic race among car and buses producers results in use of cheaper materials when usually less expensive means higher flammability and fire risk. This unfortunately is the reason of human tragedies like in Egypt or India just to mention some of the last time. Fire was jumping from one carriage to another increasing number of victims dramatically. Building industry have to use fire barriers for fire walls and doors, smoke chimneys. This report shows fire barrier materials based on composites obtained from exfoliated vermiculite and special bonding system. As bonding agent product of silicate, borate and polyphosphate polycondensation were used. The reinforcing structure was build on base of mineral and modified lignocellulosic fibres. Up to the border of 1000degreesC such composite has a good thermo insulating property. The paper also discusses influence of different additives on fire barrier efficiency.
