摘要:以玄武岩纤维、针叶木纤维为原料，通过湿法成形，辅以粘结剂和阻燃剂，制备吸音阻燃纸。探究了矿物纤维分散性、湿纸干度、粘结剂和阻燃剂用量等因素对吸音阻燃纸性能的影响。结果表明，当分散剂用量为0.006%时，玄武岩纤维分散性能达到最佳；吸音阻燃纸的适宜工艺条件为：针叶木纤维与玄武岩纤维配比为7:3，浸渍时间30s，烘干温度140℃。在此最佳制备条件下，吸音阻燃纸的含胶量为14.9%，阻燃剂含量为11.63%，定量控制在60g/m2，抗张强度为15.5N/15mm，阻燃效果达到B1级防火等级，吸音系数最高可达0.84，可满足新型建筑装饰材料对于环保性、装饰性、阻燃性和吸音性能的更高要求。

Abstract:Sound-absorbing and flame-retardant paper was prepared from basalt fibers and coniferous fibers through wet process, supplemented by binder and flame retardant. The effects of basalt fiber dispersion, wet paper dryness, binder and flame retardant dosage on the properties of sound-absorbing and flame-retardant paper were studied. It was found that the dispersity of basalt fibers reaches the best when the dosage of dispersant was 0.006%. Under the optimal preparation conditions, the binder and flame retardant content of the sound absorbing flame retardant paper were 14.9% and 11.63%, respectively. In addition, the tensile strength of paper sheet of 15.5N/15mm, the porosity of 75.60%, and the carbonization length of 43 mm, the flame retardant effect reaches B1 level flame retardant standard, and the highest sound absorption coefficient of 0.84, which meets the new building decoration materials for environmental protection, decorative, flame retardancy and sound-absorbing properties of the higher requirements.
