摘要:
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. 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 low-boiling-point 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.

One method to make vessel with heat insulation surface layer, which is to mix liquid adherence agent with heated foam particle powder, then coat above said compound paint on the planned size by continuous paper or surface of molded vessels, and then heat this paper or vessel so that this surface is foamed due to foam particle, meanwhile, this liquid adherence agent adheres to surface of this vessel, foaming layer can be formed on this surface, again cut this coating cloth and make vessel or apply to surface of this vessel, such as paper or surface of plastic vessel, which can provide head insulation effect, holder can't feel hot and scald when it is filled full of high temperature articles, it can also provide heat preservation effect; furthermore, pattern model can also be applied to surface, spray or roll above said compound paint after added pigment, the above said paint sprayed on flower pattern may foam by heating so as to form protruding colorful cubic flower pattern or printed in color after formed cubic flower pattern, which can present multiple and beautiful vision, meanwhile, this protruding cubic flower pattern can provide heat insulation function to holder, it also features in beauty, heat preservation, heat insulation and scald-proof.

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.
摘要:
The present invention provides a method of manufacturing heat insulation container including the following steps: preparing a coating material by mixing a binder of polyurethane and a thermo-expandable powder, a weight of the thermo-expandable powder being 5-20% that of the binder; coating such coating material on a continuous paper reel or the paper-made or plastics-made container; drying the coated container to form a non-foaming surface for purposes of preservation; further heating the non-foaming surface under a heat temperature of 100-140 degrees Celsius to form a foaming layer on the outer surface so as to achieve heat insulation ability.
