Modified inorganic powder material and preparation method thereof
The invention discloses a modified inorganic powder material which comprises the following components in parts by mass: 75-85 parts of inorganic powder, 3-5 parts of a surface treating agent and 10-15 parts of thermoplastic phenolic resin, the surface treating agent is coated on the surface of the inorganic powder to form a modified layer; the thermoplastic phenolic resin is coated outside the modified layer to form a thermoplastic layer; the inorganic powder contains expansible graphite with the mass fraction of 10-15% and the balance of a mixture of calcium carbonate and a silicon-containing compound; the surface treating agent is prepared from the following components in percentage by mass: 30 to 50 percent of dispersing agent and 50 to 70 percent of coupling agent. 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, poor 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3～5的表面处理剂，质量份数为10～15的热塑性酚醛树脂；所述表面处理剂包覆在无机粉体表面，形成改性层；所述热塑性酚醛树脂包覆在改性层外面，形成热塑层；所述无机粉体含有质量分数为10～15％的可膨胀石墨，其余组分为碳酸钙以及含硅化合物的混合物；所述表面处理剂由质量份数为30～50％的分散剂和质量份数50～70％的偶联剂组成。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。
