A multilayer structure and method of making the same

Abstract

The instant invention is a multi layer structure, and method of making the same. The multilayer structure according to the present invention comprises (a) one or more skin layers comprising a polymeric material; (b) one or more adhesive layers derived from one or more polyolefin dispersions; and (c) one or more base layers comprising a wood based material; wherein the adhesive layer is disposed therebetween the base layer and the skin layer.

Description

technical field [0001] The present invention relates to multilayer structures, and methods of making such structures. Background technique [0002] It is generally known to use wood-based materials such as medium density fiberboard (MDF) to manufacture furniture, such as household furniture, office furniture, cabinets, kitchen countertops, computer desks, and the like. MDF is an engineered wood product formed by breaking down softwood into wood fibers, usually in a wood chipper, mixing them with wax and resin binders, and forming panels by applying heat and pressure. It is also generally known to use polyvinyl chloride (PVC) as a skin layer attached to one or more surfaces of wood-based materials such as MDF. The use of PVC as the skin layer results in furniture that is waterproof, impact-resistant, or abrasion-resistant and aesthetically pleasing. Typically a PVC layer is laminated as the skin layer. However, vacuum molding is often used when wood-based materials such as...

Problems solved by technology

However, VAE-based emulsions generally have poor adhesion to PVC skin layers and are only useful for low-end end applications where other adhesion properties are not critical
