Problems solved by technology

Furthermore, this product cannot be post-formed as easily as conventional laminates because the veneer cracks and delamination occurs between layers during the post-forming process, and due to the use of melamine resin-treated Overlay, the natural color fidelity of the wood grain fades easily

Embodiment Construction

[0021] Referring initially to Figure 1, one embodiment of a wood veneer veneered decorative laminate 8 is shown. The laminate comprises a core 12, a resin-impregnated piece of wood veneer 14 and a cured resin coating 16 on the wood veneer. As shown, the core panel 12 of the laminate comprises one or more layers of paper sheets, such as kraft paper, that have been impregnated with a thermosetting liquid thermosetting resin, such as phenol formaldehyde resin or melamine formaldehyde resin. The core provides a structurally reinforced base for the laminate.

[0022] A preferred construction for the core ply consists of about 2-20 sheets of kraft paper having a basis weight of 80-250 grams per square meter (gsm), wherein the kraft paper is impregnated with phenolic resin, melamine resin or mixtures thereof. Typically, the liquid aqueous resin solution will have a solids content of from about 40% to about 70% and a water content of from about 30% to about 60%. As will be appreciat...

Abstract

A wood veneer surfaced laminate (8) and method of making it are provided which produces a product having the appearance of a natural wood product, but with the toughness, moisture resistance, stain resistance, impact resistance, and abrasion resistance of melamine resin surfaced laminate products. The wood veneer surfaced laminate is made by providing a sheet of a natural or engineered wood veneer (14); impregnating the sheet with a first liquid curable resin such that said liquid resin substantially completely impregnates the sheet; coating a second liquid curable resin onto a surface of the sheet; laminating the sheet to a core (12) while curing the resins to form a natural or engineered wood veneer surfaced laminate.

Description

technical field [0001] The present invention relates to wood veneer laminates, including engineered wood veneer laminates, and methods of making such laminates for use as countertops, cabinets, furniture, wall materials and surface decoration materials for other applications. Background technique [0002] Decorative laminates are well known in the art for use as surfaces for countertops, table tops, furniture, and the like. Such decorative laminates typically comprise a core formed from a plurality of resin-impregnated kraft paper sheets. Over the core is placed a decorative sheet, typically a colored cellulose paper or solid color paper with a printed graphic design, which may also be impregnated with resin. In the case of printed matter, the decorative sheet is usually covered with a transparent or translucent protective overlay comprising a resin impregnated with a resin such as melamine-formaldehyde resin or modified melamine-formaldehyde resin commonly known as "melam...
