摘要

Abstract

A new approach is provided to resolve the large-scale applications of coal tar pitch. Carbon foams with uniform pore size are prepared at the foaming pressure of normal pressure using coal tar pitch as raw materials. The physical and chemical performance of high softening point pitch (HSPP) can be regulated by vacuumizing owing to the cooperation of vacuumizing and polycondensation. Results indicate that the optimum softening point and weight ratio of quinoline insoluble are about 292℃ and 65.7%

respectively. And the optimum viscosity of HSPP during the foaming process is distributed in the range of 1000-10000 Pa·s. The resultant carbon foam exhibits excellent performance

such as uniform pore structure

high compressive strength (4.7 MPa)

low thermal conductivity (0.07 W·m

)

specially

it cannot be fired under the high temperature of 1200℃. Thus

this kind of carbon foam is a potential candidate for thermal insulation material applied in energy saving building.
