Abstract
A composition, utility material, and method of making a utility material is disclosed. A composition having an improved setting time may include a plurality of microparticles mixed with a sodium silicate binder and an isocyanate setting agent, where the microparticle composition has a setting time of less than or equal to one hour. A utility material may be a wallboard that includes the composition.
Claims19
A utility material comprising:
- a wallboard having a first facing membrane and a second facing membrane;
- and
- a core matrix disposed between the first facing membrane and the second facing membrane, wherein the core matrix includes:
- a plurality of microspheres having an outer shell and a hollow interior,
- an inorganic binder, and
- a setting agent,
- wherein the outer shell of the microspheres excludes the inorganic binder and the setting agent from the hollow interior of the microspheres;
- wherein the hollow interior of the microspheres is filled with a gas;
- and
- wherein the microspheres are from about 10 microns to about 1500 microns in size.
