Abstract

A process for manufacturing a heat insulation container mainly includes preparing a coating material by mixing a binder and a thermo-expandable powder, coating such coating material on a surface of a container and then heating the container to foam the coated material after the container is shaped. The foamed coating material is therefore provides the container with heat insulation property. The thermo-expandable powder consists of a plurality of thermo-expandable microcapsules, each of which consists of a thermoplastic polymer shell and a solvent wrapped by the thermoplastic polymer shell. To obtain a smooth surface, the soften point of the binder is required to be lower than the boiling point of the solvent.
