摘要 以粉煤灰/煤矸石纤维为原料,聚乙烯醇(PVA)与二氧化硅(SiO2)的复合物为粘合剂制得粉煤灰/煤矸石纤维保温板。探究了粘合剂的质量配合比及用量对粉煤灰/煤矸石纤维保温板性能的影响。研究结果表明:PVA∶硅酸钠(Na2SiO3)的质量配合比4∶1~5∶1,粘合剂用量介于25%~45%(体积分数)时较合适,制得的保温板的总燃烧值小于3MJ/kg,失重率小于20%,达到A级防火建材标准,且具有良好的保温性能。

Abstract: A new type of thermal insulation material with fireproofing was prepared with Fly ash/gangue fibers as raw materials and PVA-SiO2 sol as fiber binder.The effect of better process conditions on material properties was explored.The results showed that the optimum condition for this material were:m(PVA)∶m(Na2SiO3) kept from 4∶1 to 5∶1,the concentration of adhesive ranged from 25% to 40%.Under this condition,PCS of this material was less than 3MJ/kg,Δm was less than 20%.The combustion performance of this material reached A grade.
