Abstract
A fire retardant structural board is provided that includes a body of fibrous material, a triglycidyle polyester binder, a sodium borate pentahydride fire retardant, and a sodium borate pentahydride fire retardant. The body of fibrous material has a weight, first and second surfaces, first and second sides, and a thickness. The fibrous material and triglycidyle polyester are dispersed throughout the thickness of the body. The sodium borate pentahydride fire retardant is dispersed between individual fibers of the fibrous material and throughout the thickness of the body. A sodium borate pentahydride fire retardant composition also coats at least the first surface of the body.
Claims1
A fire retardant structural board for use in office structures and vehicle manufacturing, the structural board comprising of:
- an unrolled nonwoven structural mat of randomly-oriented natural fibers forming the body of the structural board;
- wherein the structural mat having a weight, first and second outer surfaces, first and second ends, first and second sides and a thickness;
- wherein the thickness of the structural mat is composed of the randomly-oriented natural fibers;
- wherein the nonwoven structural mat has a gram weight range of about 300 gsm to about 5,000 gsm;
- an epoxy polyester binder dispersed between individual natural fibers, inside and throughout the thickness of the structural mat;
- and
- wherein the nonwoven structural mat combined with the epoxy polyester binder form the characteristics of the structural board suitable for office structures and vehicle manufacturing;
- a powder borate fire retardant agent dispersed between individual natural fibers inside and throughout the thickness of the structural mat;
- wherein the mat has been calendared as part of forming the structural board wherein the calendaring determined the board's thickness and wherein the board is no longer a mat;
- a liquid based surface treatment of a fire retardant composition applied to at least the first outer surface of the mat to coat the first outer surface;
- a surfactant that broke down surface tension post cure to support absorption of liquid into the natural fibers;
- wherein the fire retardant composition comprises tetraborate pentahydride and a phosphate with about 30 percent solids;
- and
- wherein a combination of the dispersed fire retardant agent and the surface coat of the fire retardant composition results in the board's flame spread and smoke developed index pursuant ASTM E-84 testing meeting Class A.
