Patent number: 9453349Abstract: A stone-wood composite base engineered wood flooring having a composite base layer in which at least one mesh layer is embedded. The composite base layer consists essentially of approximately 40% to approximately 50% MgO, approximately 20% to approximately 45% MgCl2, approximately 9% wood powder, approximately 2.5% fiberglass mesh, approximately 0.5% Fe,03, approximately 0.5% H3PO4, and approximately 0.5% FeSO4. Adhered to the base layer is a wood veneer layer. Interlocking design such as tongue-and-groove is provided on at least two sides of the engineered flooring. The wood veneer layer of the engineered wood flooring has improved fireproof performance, waterproof performance and moisture-proof performance. When the pieces of flooring are bonded to either each other or the floor, undesired warping of joints is consequently minimized.Type: GrantFiled: October 31, 2011Date of Patent: September 27, 2016Assignee: FINISH SYSTEMS INTERNATIONAL, LLCInventor: Mondo Pallon
