20090098332Plastic Composite Panel With the Appearance and Texture Similar to Natural Lumbers - Disclosed herein is a wood plastic composite panel made of a resin composite in which wood fiber having a size of 80 to 300 meshes is included in a synthetic resin matrix, the wood plastic composite panel being provided at the entire surface thereof with an embossed structure of a lumber cut-open pattern having an average depth of 200 to 900 μm and a linear micro concavo-convex structure having an average depth of 10 to 500 μm, the panel having a reflection rate of 10 to 50% when light is incident on the surface of the panel at an incidence angle of 60 degrees. The wood plastic composite panel according to the present invention has excellent strength and durability. Furthermore, the wood plastic composite panel according to the present invention exhibits excellent appearance and texture comparable with cut-open surfaces of natural lumbers although the panel has a surface structure different from the cut-open surfaces of the natural lumbers.04-16-2009
20090206503In-Line Process for Preparing Wood Plastic Composite Panel With the Appearance and Texture Similar to Natural Lumbers and Apparatus Therefor - Disclosed herein are a method of manufacturing a wood plastic composite panel, including a panel manufacturing process of extruding and cooling a resin complex, such that wood fiber is uniformly dispersed into a synthetic resin matrix, to manufacture the resin complex into the form of a panel, an embossing process of forming a wood pattern corresponding to the cut-open surface of a natural lumber on the surface of the panel to a predetermined depth, and a brushing process of removing some of a synthetic resin layer from the surface of the panel to form linear micro concavo-convex parts to a predetermined depth, and an apparatus for manufacturing a wood plastic composite panel that is capable of efficiently performing the same. The method of manufacturing a wood plastic composite panel according to the present invention has the effect of directly realizing a wood pattern, which has the appearance and the texture similar to the open-cut surface of a natural lumber, on the surface of the wood plastic composite panel, and, at the same time, maximizing the advantage of the material comprising the wood fiber and the synthetic resin.08-20-2009
20100137513Process for Preparation of Composite Containing Wood Fiber Component and Polymer Resin - Provided is a process for preparing a wood fiber-polymer composite containing a wood fiber component and a polymer resin, comprising inducing chemical bonding reaction between the wood fiber and polymer by application of an ultrasonic wave upon contact of the wood fiber component with the molten polymer resin. The process of the present invention enables production of a composite having superior mechanical, thermal and Theological processing properties, by induction of chemical bonding between the wood fiber and polymer resin even without use of additional additives. Consequently, the present invention provides advantages such as reduction of composite production costs, no need to select and change kinds of additives corresponding to components of the composite and thereby high flexibility of manufacturing process.06-03-2010
20120067665SOUND-ABSORBING NOISE BARRIER - A sound-absorbing noise barrier, more specifically to one comprising: a main body which has a front surface and a rear surface and extends horizontally and in which a space is formed between the front surface and the rear surface; and a sound-absorbing material which is accommodated in the space of the main body and is disposed at a distance away from the front surface and the rear surface respectively, wherein the front surface of the main body is formed with vertically oriented alternating projections and recesses and is formed with a plurality of sound-absorbing holes, and the overall cross-sectional area of the sound-absorbing holes is at least 20% of the cross-sectional area of the front surface. The sound-absorbing noise barrier of the present invention can be variously employed in construction and industrial products, has good sound-absorbing characteristics across a wide frequency range, and can present an aesthetically appealing external effect.03-22-2012
