摘要
以膨胀珍珠岩和热固性酚醛树脂为原料,盐酸磷酸混合酸为固化剂,制备膨胀珍珠岩/酚醛树脂轻质复合材料。运用单因素研究法探究了固化剂用量、加热成型温度、加热成型时间、主要原料的比例及酚醛树脂预热温度对轻质复合材料性能的影响。结果表明,固化剂用量为酚醛树脂质量的12%,固化温度为120℃,加热时间为2 h,酚醛树脂与膨胀珍珠岩的质量比为3.50时复合材料性能最优。其抗压强度为1.476 MPa,抗折强度为1.148 MPa,导热系数为0.048 W/(m·K),密度为320 kg/m3。
The vitrified microsphere/phenolic resin lightweight composite materials were prepared with expanded perlite and thermosetting phenolic resin as raw material, adding hydrochloric acid and phosphoric acid as curing agent. The influence factors on the properties of the composite material were discussed with the single factor experiment method, such as the curing agent dosage, the thermoforming temperature, the thermoforming time, the raw material composition and the preheating temperature of phenolic resin. The results showed that favorable performance of lightweight composite materials could be achieved through the optimized conditions, including the curing agent is 12% of phenolic resin, the thermoforming temperature is 120 ℃, the thermoforming time is 2 h, the quality ratio of the phenolic resin to expanded perlite is 3.50. For this optimal sample, the compressive strength is 1.476 MPa, flexural strength is 1.148 MPa, thermal conductivity is 0.048 W/（m.K） and the density is 320 kg/m3.
