混合发泡剂FAB⁃1在冰箱硬泡中的应用

摘要

The application situation of FAB?1 as blended blowing agent for rigid polyurethane foam applied in refrigerators was introduced. The compatibility of FAB?1 with polyols, with base materials, and the comparison with other blowing agents, the application of FAB?1 blended with CP , the stability of foam blends were investigated. The results showed that the thermal conductivity ( 10 ℃) of rigid foams using blowing agent FAB?1 was 17. 63 mW/( m·K) .%主要介绍了基于顺式HFO?1336mzz的混合发泡剂FAB?1在冰箱硬泡中的应用情况.研究了FAB?1与多元醇的相容性、与常用基材的兼容性、与其他发泡剂的差异、与环戊烷(CP)的混配应用,以及FAB?1发泡体系组合聚醚的储存稳定性.结果表明,FAB?1发泡制得的聚氨酯硬泡导热系数(10℃)可低至17.63 mW/(m·K).
