摘　　要：酚醛泡沫作为一种重要的煤矿填充密闭材料,在其成型过程中甲醛释放量直接影响使用安全性。为有效评价其释放规律,本研究采用乙酰丙酮法分析了酚醛泡沫成型过程中温度、湿度、成型时间对甲醛释放量的影响。甲醛释放量较大的成型条件为:温度29℃,相对湿度40%,成型时间5 min。在该条件下,甲醛的释放浓度为4.954 mg/m^(3)。Phenolic foam is an important filling and sealing material for coal mines.The formaldehyde emission during the molding process of phenolic foam directly affects the use safety.In order to effectively evaluate its release rule,the acetylacetone method was used to analyze the influence of temperature,humidity,and molding time on formaldehyde emission of phenolic foam.The results showed that the molding conditions of high formaldehyde emission were as follows:temperature of 29℃,relative humidity of 40%,molding time of 5 min.Under these conditions,the formaldehyde emission concentration was 4.954 mg/m^(3).
