Intumescent carbon-silicon flame retardant, preparation method thereof and flame-retardant polyester fiber board
The invention relates to the field of flame retardant preparation, in particular to an intumescent carbon-silicon flame retardant and a preparation method thereof and a flame-retardant polyester fiberboard, the intumescent carbon-silicon flame retardant comprises the following raw materials: 50%-60% of sodium silicate, 5%-6% of an alkaline agent and the balance of neutral water, the pH value of the solution is 12-13, and the intumescent carbon-silicon flame retardant is prepared by adopting a flame-retardant mechanism that silicon dioxide is generated during combustion. Compared with a traditional flame-retardant mechanism of filling flame retardance with nano silicon dioxide, the flame retardant is uniform in distribution and higher in utilization rate, the production cost is reduced, adhesion is firm, the powder falling phenomenon is avoided, and the A-level flame-retardant effect can be achieved. When the flame retardant is applied to the organic fiber acoustic board, the flame retardant effect is improved, the influence of the flame retardant on the sound absorption effect of the organic fiber acoustic board is reduced, and the hardness of the board is improved.
本发明涉及阻燃剂制备领域，尤其是膨胀型炭硅阻燃剂及其制备方法和阻燃聚酯纤维板，包括原料为：硅酸钠:50％‑60％，碱剂：5％‑6％，中性水：余量，溶液的PH值在12‑13之间，采用燃烧时，产生二氧化硅的阻燃机理，相对于传统的纳米二氧化硅进行填充阻燃的阻燃机理，该阻燃剂分布均匀，利用率更高，降低了生产成本，且附着牢固，不产生“掉粉现象”，可达到A级阻燃效果。在应用于有机纤维吸声板上时，不仅提高了阻燃效果，而且降低了阻燃剂对有机纤维吸声板的吸声效果的影响，且提高了板材的硬度。
