| 摘要 |
The invention and formulation relates to methods, materials, and products for foam-in-place materials comprising a two-component foam-in-place structural material for producing a foamed product. A first component of the system includes an epoxy-based resin preferably formulated with a coated particles, such as a metal salt, a metal carbonate encapsulated within a wax, or a polymer, (e.g., Thermoset, thermoplastic, or mixture). The metal carbonate particle may be encapsulated within a wax, shell or skin that will change state to expose the core to chemically react for initiating the production of gas for blowing. The second component is an acid that is capable of initiating polymerization of the resin. A reactive mixture is achieved through the combination of the first and second components wherein heat from the exothermic reaction of the acid with the epoxy component causes the thermoplastic shell, skin, or wax encapsulating a metal carbonate core to soften or melt thereby exposing the metal carbonate to the reactive mixture.
