摘要: 通过添加MFT成核剂，制备出泡孔均匀细腻的聚氨酯硬泡，降低泡沫固相导热系数和辐射导热系数，当MFT成核剂添加3份时，泡沫孔径可降低三分之一，导热系数下降5.5%，与LBA发泡体系保温效果相当。
Abstract: By adding MFT nucleating agent, polyurethane rigid foam with uniform and fine pores was prepared, and the thermal conductivity and radiative thermal conductivity of the foam were reduced. When 3 parts of MFT nucleating agent were added, the pore size of the foam was reduced by one-third and the thermal conductivity decreased by 5.5%, which was equivalent to the thermal insulation effect of LBA foaming system.
