Abstract
The present invention relates to a ceramized silicone resin composition and a pre-preg and a laminate that use the composition. The ceramized silicone resin composition comprises: 50-100 parts of a condensation-type silicone resin, 0.0001-2 parts of a catalyst, 5-80 parts of a ceramic-forming filler, and 0.01-50 parts of a flux. The pre-preg and the laminate manufactured using the ceramized silicone resin composition, when used in a sustained high temperature, can transform into complex ceramized structure thereby providing ceramic properties, thus providing great fireproof and flame retardant effects; also, manufacturing of the laminate is similar to that of a regular FR-4 laminate, where the process is easy to operate. The ceramized silicone resin composition, the pre-preg, and the laminate have the advantages of being halogen-free, low smoke, low toxicity, flame retardant, and fireproof, provide a novel concept and a novel method in terms of flame retardancy and fire resistance, accelerate the research progress in laminate passive fire protection technology, and have broad prospects in the field of fire protection and fire resistance.
