Fire blocking material include: organic fire blocking materials, inorganic fire blocking materials fire retardant package. Organic fire blocking material is organic synthetic resin adhesives, adding fire retardants, fillers, etc. made by rolling. The blocking material does not solidify long, good plasticity, can arbitrarily block. This blocking material mainly used in construction pipes and wires and cables through holes in the fire blocking the project, and with the inorganic fire blocking material, with the use of fire retardant package. Inorganic fire blocking material, also known as speed solid-fire blocking material, is quick-drying adhesive as the base material, adding fire retardant, refractories by grinding, mixing together. The product of the pipe or wire and cable through-holes, particularly large holes, the hole plugging effect between floors better. Not only does it reach the fire resistance required, but also have a very high mechanical strength, and hardness of cement board floor is almost the same.
