RESEARCH OF SILICA AEROGEL/POLYURETHANE HEAT INSULATION MATERIAL

Abstract

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.

Key words: silica aerogel, polyurethane, heat insulation
