摘　　要：以自制硅溶胶和铝溶胶为阻燃体系,研究阻燃浸注处理压力、处理时间、阻燃成分含量及样品不同处理方式等对建筑用竹制脚踏板防火阻燃性能的影响。试验结果表明:硅溶胶比铝溶胶更易渗入到竹片内部;在真空条件下以硅溶胶对竹片进行阻燃浸注处理时,浸注时间越长、阻燃体系中阻燃组分含量越高,所得样品的载药率和氧指数越高;样品的不同阻燃处理方式对其载药率和氧指数有较大影响。Utilize the self-making silica sol and aluminum sol, the effects of fire-retardant impregnating pressure, impregnating time, the content of fire-retardant component and the dif ferent treatment styles on the fire retardant property of bamboo footboard used in building construction have been studied. The experimental results show that： compare with the aluminum sol, silica sol is more easily to be impregnated into the bamboo; fire-retardant treatment of bamboo footboard under vacuum, longer time of the fire retardant treatment and higher content of fire-retardant component in fire-retarding system are favorable to improve the drug-loading rate and oxygen index of the sam- pies; in addition, different fire-retardant treatment styles have great effect on the drug-loading rate and the oxygen index of the samples.
