Problems solved by technology
Although polycrystalline mullite fiber has excellent flame retardant and thermal insulation properties, its fibers are loose, so its tensile strength and bending strength are poor, which makes it easy to damage during use, which in turn limits its normal use

The invention discloses a polycrystalline mullite fiber with strong fire resistance and a preparation method, and relates to the technical field of fireproof materials, the polycrystalline mullite fiber with strong fire resistance comprises a fixed plate, a polycrystalline mullite fiber module and a heat conducting plate, the heat conducting plate, the polycrystalline mullite fiber module and the fixing plate are sequentially and fixedly installed together from top to bottom to form the fireproof module body, and the polycrystalline mullite fiber module has the advantages of being good in high temperature resistance, thermal shock resistance and corrosion resistance and low in heat conductivity and has a wider application range; polyether polyol, isocyanate, microporous mullite aggregate and glass fibers are added into the polycrystalline mullite fiber module, the overall hardness and toughness of the fireproof module are effectively improved, meanwhile, an arc-shaped supporting plate is fixedly installed on the upper surface of a fixing plate and supports a heat conduction plate, and the heat conduction plate is fixed to the upper surface of the fixing plate; the situation that high-temperature and high-pressure air impacts the heat-conducting plate for a long time, and consequently the heat-conducting plate is sunken is avoided, and the service life of the fireproof module is prolonged.
Description
technical field [0001] The invention relates to the technical field of fireproof materials, in particular to a polycrystalline mullite fiber with strong fire resistance and a preparation method. Background technique [0002] With the continuous increase of the degree of industrialization, the types and quantities of industrialized equipment are increasing day by day. However, the fireproof performance of the equipment cannot meet the needs of the market. For this reason, a layer of fireproof material is often installed on the side wall of the equipment for fireproofing and heat preservation. However, Existing materials cannot meet market requirements, with high thermal conductivity, poor thermal insulation performance, poor energy saving and fire resistance. [0003] Polycrystalline mullite fiber is a new type of ultra-light high-temperature refractory fiber at home and abroad. It is one of the whole dichloride trioxide and silica-based ceramic fibers. State fiber 200 ~ 400...
