摘　　要：环戊烷 + LBA + R600多元发泡体系能较好的满足电热发泡技术要求,泡料的流动性好,产品的泡沫密度分布差更小,泡沫泡孔的孔径分布均匀,具有更低的泡沫导热系数,产品能效余量较纯环戊烷和环戊烷 + 245fa二元发泡体系分别有3.3%和1.4%的提升,长期保温性能较稳定,可节省泡料10%~15%,降低发泡原料成本。The cyclopentane + LBA + R600 multi-component foaming system can better meet the technical requirements of electrothermal foaming. The foam has good fluidity, the product’s foam density distribution difference is smaller, the pore size distribution of foam cells is uniform, and the thermal conductivity of foam is lower. The energy efficiency margin of the product is 3.3% and 1.4% higher than that of the pure cyclopentane and cyclopentane + 245fa binary foaming systems, respectively. The long-term thermal insulation performance is relatively stable, which can save 10%~15% of foam materials and reduce the cost of foaming raw materials.
