摘要/Abstract

摘要： 舰船用隔热材料的相关研究在船舶设计及建造过程中长期受到关注。高性能的隔热绝缘材料不仅可以改善舰船的居住环境,还能提高舰船的安全性和服役寿命。为了获得高性能的隔热材料,以聚氨酯作为基体,以二氧化硅气凝胶为热阻填料,通过共混的方式制备了二氧化硅(SiO₂)气凝胶/聚氨酯(PU)隔热材料,使用导热系数仪、万能力学试验机等手段表征了PU隔热材料的性能。确定了SiO₂气凝胶/PU隔热材料的最佳配方为电动混合方式下制得的2 g SA-A1/100 g PU隔热材料,导热系数达到最低值,为0.091 W/(m·K),拉伸强度为3.6 MPa。

Abstract: The study of ship′s thermal insulation materials has gained extensive attention during the design and construction of ships. The high performance insulation materials can improve the ship′s living environment, and improve the safety and service life of the ship. In order to obtain high performance insulation materials, in this paper, by using polyurethane (PU) as matrix, silica aerogel (SA) as filler, thermal insulation materials was prepared by blending, The properties of the PU insulation materials were characterized by thermal conductivity test, vertical combustion testand other methods. The best prescription of silica aerogel/polyurethane thermal insulation material is 2 g SA-A1/100 g PU insulation materialsby electric blending. The thermal conductivity of the insulation material was 0.091 W/(m·K), and the tensile strength was 3.6 MPa.
