摘要
以工业废碱渣(主要组分为氢氧化铝(Al(OH3)))、硼酸锌(2ZnO.3B2O3.3.5H2O)、硼酸(H3BO3)等为阻燃剂,制备出具有良好阻燃性能的阻燃高密度松木纤维板(HDF),对其物理及力学性能、阻燃性能、残炭形貌等进行了分析表征。结果表明:在满足物理及力学性能的条件下,废碱渣Al(OH3)与2ZnO.3B2O3.3.5H2O和H3BO3之间具有良好的阻燃协效性,提高了纤维板的成炭性,残炭量达到22.2%,降低了总释热量,降低幅度为32%,使其氧指数提高到36.4%,垂直燃烧等级达到V-0级。
High density pine fiberboard （HDF） with good fire performance was successfully prepared by using flame retardants of industrial by2 product（mainly composed of aluminum trihydrate AI（OH）3）, zinc borate （2ZnO . 3B2O3. 3.5 H20） and boric acid （H3BO3）. The mechanical properties, flame retardancy and char morphology were characterized and analyzed. The results show that there is a good synergistic effect on the flame-retardancy between Al（OH）a and 2ZnO . 3B203 . 3.5H20 and H3BOa which can enhance the char formation up to 22.2% and reduce the total heat release with a dop of 32%, while the mechanical properties are well maintained. The limited oxygen index （LOI） of the flame retardancy board can reach up to 36.4%0 and the vertical burning test can reach V- 0.
