| Abstract: | The properties of polyurethane affixed with solid sodium silicate by physical method can be changed. The relation between sodium silicate increment, granularity and some properties of polyurethane, such as heat deformation, heat transmission coefficient and pressure tolerance intensity, was discussed in this paper. It was proved that the heat resistibility of PU was improved, the cost was lowered, and this polyurethane reached the level of heat preservation material of PU. It's a cheap heat preservation material with a good application. |
