Foam, composition, and method

摘要

A method of producing a foam is disclosed. The method includes providing an epoxy-containing compound, a cationic catalyst, an optional blowing agent, and at least one additive. The method further includes combining the epoxy-containing compound with the cationic catalyst, the optional blowing agent, and the at least one additive, wherein the epoxy-containing compound and the cationic catalyst react to polymerize the epoxy-containing compound to provide the foam having a density from about 0.3 lbs/ft3 to about 5.0 lbs/ft3 as measured by ASTM D1622. Further disclosed are the foam and a method for installing the foam.

1. A method of producing a foam comprising providing a composition consisting of an epoxy-containing compound, a cationic catalyst consisting of a superacid, a BF3 dihydrate complex, a phosphoric acid derivative, or combination thereof, an optional blowing agent, and least one of a surfactant, a flame retardant, a catalyst carrier, or a co-reactant consisting of a diol, a glycerin, or a combination thereof, and combining the epoxy containing compound with the cationic catalyst, the optional blowing agent, and the least one of a surfactant, a flame retardant, a catalyst carrier, or a co-reactant consisting of a diol, a glycerin, or a combination thereof, wherein the epoxy-containing compound and the cationic catalyst react to polymerize the epoxy-containing compound to provide an epoxy matrix and an isocyanate free foam; the foam having a density from about 0.3 lbs/ft3 to about 5.0 lbs/ft3 as measured by ASTM D1622.
