Background
The ceramic flame-retardant technology belongs to a subdivision field of flame-retardant materials. Conventional flame retardant materials pyrolyze or burn when exposed to high temperatures or open flames, and the resulting residue is a loose, non-strong, powdered residue. By adding a certain amount of porcelain forming filler, fluxing agent, flame retardant and other processing aids or silane compounds into a matrix, the mechanical property of the ceramic polymer has similar properties to that of a common high molecular material in a normal use environment. When exposed to open fire ignition or in a high temperature environment, the composite material can be transformed into a ceramic-like body with certain bending strength and compressive strength. The flame can be prevented from spreading to the inside of the polymer and spreading to the periphery, thereby achieving the aim of fire prevention.
