Abstract
The invention comprises a method of insulating a structure. The method comprises providing a quantity of a foam-forming composition between structural elements and permitting the foam-forming composition to expand to form a foam. The foam-forming composition comprises an aqueous emulsion or solution of a natural or synthetic film-forming polymer, a surfactant, hydrogen peroxide and an activating agent which causes the hydrogen peroxide to release oxygen gas sufficient to produce a foam. An insulated structure is also disclosed.
Claims43
A method comprising:
- providing a quantity of a foam-forming composition between structural elements;
- and
- permitting said foam-forming composition to expand to form a foam, said foam-forming composition comprising:
- an aqueous emulsion or solution of a natural or synthetic film-forming polymer;
- a surfactant;
- hydrogen peroxide;
- and
- an activating agent which causes said hydrogen peroxide to release oxygen gas sufficient to produce a foam.
An insulated structure comprising:
- a first structural component;
- a second structural component;
- and
- a foam composition at least partially disposed between said first and second structural components, said foam being formed in situ from a composition comprising:
- a latex emulsion or solution of a natural or synthetic film-forming polymer;
- a surfactant;
- hydrogen peroxide;
- and
- an activating agent which causes said hydrogen peroxide to release oxygen gas sufficient to produce said foam.
An insulated structure comprising:
- a first structural component;
- a second structural component;
- and
- a foam composition at least partially disposed between said first and second structural components, said foam composition comprising:
- a latex emulsion or solution of a natural or synthetic film-forming polymer;
- and
- a surfactant;
- and
- wherein said foam composition is free of hazardous volatile organic compounds.
A method comprising:
- producing a foam by mechanically frothing a composition comprising:
- a latex emulsion or solution of a natural or synthetic film-forming polymer;
- and
- a surfactant, wherein said foam is free of hazardous volatile organic compounds;
- and
- disposing said frothed foam on structural element to be insulated.
A method comprising:
- providing a quantity of a foam-forming composition on a substrate to be insulated;
- and
- permitting said foam-forming composition to expand to form a foam, said foam-forming composition comprising:
- an aqueous emulsion or solution of a natural or synthetic film-forming polymer;
- a surfactant;
- hydrogen peroxide;
- and
- an activating agent which causes said hydrogen peroxide to release oxygen gas sufficient to produce a foam.
A method comprising:
- combining an aqueous emulsion or solution of a natural or synthetic film-forming polymer, a surfactant, hydrogen peroxide and an activating agent to form a foam-forming composition;
- applying said foam-forming composition to a substrate;
- permitting said foam-forming composition to produce a foam by the decomposition of said hydrogen peroxide;
- and
- permitting said foam-forming composition to dry and cure.
An insulating foam composition comprising:
- a latex emulsion or solution of a natural or synthetic film-forming polymer;
- a surfactant;
- hydrogen peroxide;
- and
- an activating agent which causes said hydrogen peroxide to release oxygen gas sufficient to produce said foam.
A method comprising providing a quantity of a foam composition between structural elements, said foam composition comprising:
- an aqueous emulsion or solution of a natural or synthetic film-forming polymer;
- and
- a surfactant;
- said foam composition being formed by mechanical frothing and being substantially free of undesirable VOCs.
