Abstract
A building assembly system that comprises thermoformed high density polyethylene molded components filled with high density polyurethane foam. The molded components are configured in a cube or triangle form and secured against a steel frame to provide a habitable constructed unit. The composition of the high density polyethylene molded components filled with high density polyurethane foam meets standards for the American Society for Testing and Materials for a habitable structure used by humans. The habitable structure can be used on land or water.
Claims6
A molded component made from thermoformed material for a building assembly used on land or water, the molded component is at least sufficient to meet a minimum ASTM standard of two or more of the following:
- ASTM D695-15, ASTM D638-14, ASTM D732-17, ASTM C518-17, ASTM D4976-12a, ASTM E72-15, ASTM E108-16, ASTM D4819-13, ASTM D570-98, ASTM D6341-16, ASTM D2990-17, ASTM E2322-03, ASTM E2126-11, ASTM D1435-13, ASTM G154-12a, ASTM D7989-15, NFPA 286-15, and UL 790-2014,
- the molded component comprising:
- a skin composition surrounding a polyurethane foam composition, the skin composition comprising a flame retardant mixed with a polyethylene, wherein the polyethylene comprises approximately 70 weight percent of the skin composition and the flame retardant comprises approximately 30 weight percent of the skin composition
- wherein the flame retardant comprises:
- melamine polyphosphate in approximately 72-78 weight percent of the flame retardant and polyethylene in approximately 22-28 weight percent of the flame retardant.
A formulation of a thermoformed molded component for use in a building assembly comprising:
- a skin composition of the thermoformed molded component for use in a building assembly comprising a flame retardant mixed with a polyethylene, wherein the flame retardant comprises approximately 30 weight percent of the skin composition and the polyethylene comprises approximately 70 weight percent of the skin composition;
- and
- a foam composition, surrounded by the skin composition, the foam composition comprising a first component comprising diphenylmethane diisocyanate, and a second component of the foam composition;
- wherein the flame retardant comprises:
- melamine polyphosphate in approximately 75 weight percent of the flame retardant and polyethylene in approximately 25 weight percent of the flame retardant;
- wherein the polyethylene comprises a polyethylene hexene copolymer;
- wherein the thermoformed molded component is at least sufficient to meet a minimum ASTM standard of two or more of the following:
- ASTM D695-15, ASTM D638-14, ASTM D732-17, ASTM C518-17, ASTM D4976-12a, ASTM E72-15, ASTM E108-16, ASTM D4819-13, ASTM D570-98, ASTM D6341-16, ASTM D2990-17, ASTM E2322-03, ASTM E2126-11, ASTM D1435-13, ASTM G154-12a, ASTM D7989-15, NFPA 286-15, and UL 790-2014.
