High-strength silicon fiberboard and preparation method thereof
The invention discloses a high-strength silicon fiberboard, which is prepared from the following raw materials in parts by weight: 10 to 40 parts of inorganic composite fiber, 40 to 70 parts of fire-resistant filler, 10 to 30 parts of inorganic binding agent, 2 to 10 parts of flocculating agent and 2000 to 5000 parts of water, the inorganic composite fibers comprise polycrystalline mullite fibers and quartz fibers; the fire-resistant filler is composed of talcum powder, Suzhou soil and industrial Al2O3. The fireproof filler can generate cordierite powder in the sintering process of the fiberboard, and the sintered cordierite powder is filled in fiber interlaced gaps to serve as a main body of the fireproof filler, so that the ceramic fiberboard has an extremely low thermal expansion coefficient and excellent high temperature resistance, and provides rigid support for the fiberboard; fibers can be well protected at high temperature, and the thermal shock resistance of the fiberboard is greatly enhanced.
本发明公开了一种高强度硅系纤维板，包括以下重量份原料：10‑40份的无机复合纤维、40‑70份的耐火填料、10‑30份的无机结合剂、2‑10份的絮凝剂以及2000‑5000份的水；所述无机复合纤维包括多晶莫来石纤维和石英纤维；所述耐火填料由滑石粉、苏州土、工业Al2O3构成。本发明中的耐火填料在纤维板烧结的过程中会生成在堇青石粉，本发明中烧结出的堇青石粉填充于纤维交织的空隙之中作为耐火填料的主体，使得陶瓷纤维板具有极低的热膨胀系数和优良的耐高温性，并为纤维板提供刚性支撑，高温下能很好的保护纤维且极大增强了纤维板的抗热震性能。
