PROCESS FOR COATING A FOAMED COATING MATERIAL ON A CONTAINER OR THE LIKE

摘要

A process for coating a foamed coating material on a container or the like mainly includes preparing a coating material by heat blending or kneading a solid thermoplastic binder with a solid thermo-expandable powder consisting of a plurality of solid thermo-expandable microcapsules till the solid thermoplastic binder being gelatinized so that the thermo-expandable microcapsules being uniformly spread in the gelatinized thermoplastic binder, coating such coating material on a surface of a container and then heating the container to foam the coated material. The foamed coating material is therefore provides the container with heat insulation property.
