【 摘 要 】

For mica, low-melting glass powder and flame retardant added to silicone rubber fireproof glass, the fire resistance of fireproof glass after adding different materials was studied. It was found that the cross linking effect was the best when the amount of DCP added with vulcanizing agent was 1wt%. After adding mica, the tensile strength of glass burning decreased, and the elongation at break was the maximum at 30wt%, reaching 97.9%. At the same time, after the burning of the ceramic material, the strength is more rigid. After the combustion of the silicone rubber system, it gradually changes from the collision state to the contracted state, and the critical point of the morphological change is 50 wt%, mica. At the same time, the layered eutectic structure was observed by scanning electron microscopy. The mica content was higher and the eutectic state was denser. For this reason, the mica content was 40 wt%. After the addition of the low-melting glass flit, the mechanical properties are worse, and the volume of the ceramics shrinks faster, but the strength is increased and the heat resistance is better. The test data found that after the addition of the flame retardant, the content of MH decreased after the addition of the flame retardant synergism, although the mechanical properties decreased slightly, but the flame retardant properties remained unchanged. In addition, the TGA test and solvent resistance test data show that the thermal stability and solvent resistance of the synergistic flame retardant system with APP addition is better than other synergistic systems.
