Modified inorganic powder material and preparation method thereof
The invention discloses a modified inorganic powder material which comprises the following components in percentage by mass: 75-85% of inorganic powder and 15-25% of thermoplastic phenolic resin, and the thermoplastic phenolic resin is coated on the surface of the inorganic powder. The inorganic powder contains the following components in percentage by mass: 10-15% of expandable graphite, 0-90% of porous calcium carbonate and 0-90% of porous calcium silicate. The technical problems that in the prior art, a fireproof plate prepared by adding inorganic powder into a thermosetting adhesive is complex in forming process, low in mechanical property, low in fire resistance and difficult to recycle are solved.
本发明公开了一种改性无机粉体材料，包括质量份数为75～85％的无机粉体，质量份数为15～25％的热塑性酚醛树脂，所述热塑性酚醛树脂包覆在无机粉体表面；所述无机粉体含有质量分数为10～15％的可膨胀石墨，0～90％的多孔碳酸钙以及0～90％的多孔硅酸钙。解决了现有技术中无机粉体加入热固性胶粘剂制成的防火板材成型工艺复杂、力学性能低、耐火性差，难以回收利用的技术问题。
