Decoration film using natural cork materials and method for manufacturing the same

Abstract

Disclosed is a decoration film using natural cork materials which has cost competitiveness over the conventional real wood parts and can be manufactured in an open skin type by implementing natural wooden feature on the surface. Methods of manufacturing the decoration film are also disclosed. In particular, the decoration film using natural cork materials includes: a base material layer as the bottom layer; a middle layer bonded onto the base material layer; and a cork layer that is the top layer bonded onto the middle layer. The middle layer of the decoration film includes a bottom bonding layer, a non-woven fabric layer bonded onto the bottom bonding layer, and a top bonding layer bonded onto the non-woven fabric layer.

Description

technical field [0001] The present invention relates to a decorative film using natural cork material and a method for manufacturing the decorative film which are cost-competitive with conventional solid wood products. Background technique [0002] Generally, interior parts such as crash pads in front of the driver's seat and passenger seat, panels assembled with the crash pads around the instrument panel, a center panel where audio systems, cup holders, ashtrays, etc. are mounted, are generally arranged in a vehicle, and As a headliner for roof components and these interior components are made of different materials. [0003] Recently, interior materials made of solid wood have been used to achieve a refined and elegant appearance. [0004] In the related art, traditional wooden products made of solid wood are manufactured by: preparing a substrate; placing solid wood parts on the substrate; and then coating / grinding the solid wood surface in Polished and smoothed to prov...

Problems solved by technology

[0005] However, when the related art solid wood product is used to form an automobile interior material, or when a related art solid wood material is used to manufacture shaped parts such as automobile interior parts, the process may become complicated and the manufacturing cost may increase

[0006] In addition, due to the raw material cost of solid wood, it may not be possible to use the above-mentioned solid wood products in general vehicles, except for high-end luxury vehicles

In addition, since solid wood or wood chips need to be used together with aluminum sheets and craft veneer (veneer) due to their brittle characteristics, solid wood products may not be able to be manufactured in a separate form, so the cross-sectional structure of the formed part is quite complicated ( Figure 5 )
