Abstract
A method of insulating a substrate or a portion thereof by depositing a syntactic foam by a spraying, dipping or a variety of printing processes. The foam comprises void containing particles in expanded form, unexpanded form, or a mixture of these. The deposited foam is dried to remove solvents and cured to strengthen the binder which restrains the microspheres. Heating may also expand the unexpanded microspheres. A tie coat may be applied to promote adhesion between the substrate and the insulating syntactic foam. Multiple layers of the syntactic foam may be applied to increase the thickness of the resultant layer for providing a controlled amount of increased insulation.
Claims31
A method of making a syntactic foam insulated container comprising:
- depositing a first layer of a syntactic foam at a controlled thickness upon a first surface of a substrate for creating an insulating layer providing a controlled amount of insulation;
- curing the syntactic foam for strengthening it;
- cutting the substrate with the cured syntactic foam layer thereon for preparing a blank;
- and
- forming the blank into a preform of the container.
A method of making a syntactic foam insulated container comprising:
- printing a first layer of a syntactic foam of a controlled thickness upon a first surface of a substrate for creating an insulating layer providing a controlled amount of insulation;
- curing the first layer of syntactic foam for strengthening it;
- depositing at least one additional layer of a controlled thickness of syntactic foam over the first layer of syntactic foam;
- curing the additional layer of syntactic foam for strengthening it;
- cutting the substrate with the cured layers of syntactic foam thereon for preparing a blank;
- and
- forming the blank into a preform of the container.
A method of making a syntactic foam insulated container comprising:
- printing a first layer of a syntactic foam of a controlled thickness upon a first surface of a substrate for creating an insulating layer to provide a controlled amount of insulation wherein the first layer of syntactic foam forms an interrupted pattern of closely spaced elements;
- curing the syntactic foam for strengthening it;
- cutting the substrate with the cured syntactic foam layer thereon for preparing a blank;
- and
- forming the blank into a preform of the container.
