Abstract
A simultaneous interpenetrating polymer network—geopolymer epoxy composition includes a first component comprised of a waterborne epoxy curing agent and an alkaline silicate solution, and a second component comprised of an epoxy resin and an aluminosilicate. The two components are mixed to produce a SIN-GE composition that cures at ambient temperatures. The SIN-GE composition may be a low-viscosity, sprayable composition, or may be a higher-viscosity composition. The compositions may be used as coatings, adhesives, mortars, casting materials, and the like.
Claims20
A geopolymer-epoxy composition comprising:
- a) a first component comprising a waterborne epoxy curing agent, at least one surfactant and an alkaline silicate solution;
- and
- b) a second component comprising an epoxy resin and an aluminosilicate source,
- wherein, when mixed together, said first and second components form a simultaneous interpenetrating polymer network—geopolymer and epoxy (SIN-GE) composition that cures at ambient temperature.
A method of making a geopolymer-epoxy composition, the method comprising:
- a) preparing a first component by combining a waterborne epoxy curing agent, at least one surfactant and an alkaline silicate solution;
- b) preparing a second component by combining an epoxy resin and an aluminosilicate source;
- and
- c) mixing together the first and second components,
- wherein, when mixed together, said first and second components form a simultaneous interpenetrating polymer network—geopolymer and epoxy (SIN-GE) composition that cures at ambient temperature.
A geopolymer-epoxy composition comprising:
- a) a first component comprising about 7.1% by weight of a waterborne epoxy curing agent, about 17.9% by weight of water, about 2.3% by weight of surfactant and about 11.6% by weight of an alkaline silicate solution;
- and
- b) a second component comprising about 54.9% by weight of an epoxy resin and about 6.2% by weight of an aluminosilicate,
- wherein, when mixed together, said first and second components form a SIN-GE composition that cures at ambient temperature.
