以膨胀珍珠岩、酚醛树脂为原料,添加适量助剂,采用热压成型方法制备膨胀珍珠岩/酚醛树脂复合保温材料,探讨了酚醛树脂用量、压缩比、热压温度、保压时间和固化剂对复合材料性能的影响.实验表明,制备复合材料的优化条件为酚醛树脂用量40％、压缩比2.0、热压成型温度220℃、保压时间2h、固化剂(六亚甲基四胺)用量3％,所得复合保温材料的密度为309.56 kg/m3,导热系数为0.047 W/(m·K),抗折强度为1.147 MPa,抗压强度为1.331 MPa.%Using hot embossing method, the expanded perlite/phenolic resin composite insulation material was prepared based on expanded perlite and phenolic resin as raw material,and with addition of several kinds of supplementary reagents. The influence factors such as the amount of the phenolic resin.the compression ratio,the hot pressing temperature,the pressing time, and the cur ing agent on the properties of composites were discussed. The results showed that the optimized conditions for the composite prepa ration are that when the amount of the phenolic resin is 40%,the compression ratio is 2.0,the hot pressing temperature is 220 ℃., the pressing time is 2 h,and the curing agent (hexamine) is 3%. The density of the resulting material is 309.56 kg/m3, thermal conductivity is 0.047 W/(m·K) ,flexural strength is 1.147 MPa,and compressive strength is 1.331 MPa.
