Problems solved by technology

However, the problem with these methods is that they cannot satisfy people's desire for natural patterns without leaving artificial traces
In addition to this, a certain thickness needs to be maintained in order to provide durability in use, leading to a problem of further reduction in transparency due to the thickness
[0010] Third, polyvinyl chloride resin has the problem of poor heat resistance. Due to the low softening point of polyvinyl chloride from 80 to 100 ° C, its surface is easily damaged by heat sources exceeding 100 ° C
[0015] The conventional decorative board coverings having these structures have problems in that the fidelity of the decorative pattern of the non-foamed sheet layer 21 is lowered, the transparency of the polyvinyl chloride resin skin layer 22 providing durability is lowered, and its heat resistance is insufficient.

Abstract

The present invention provides a decorative panel covering comprising a surface layer and a substrate layer of an underlayer, wherein the surface layer comprises a polyethylene terephthalate film layer and a method for producing the same. In addition, the present invention provides a decorative panel covering comprising a base layer of a surface layer and an under layer, and a method for producing the same, wherein a lightweight base layer is further contained under the base layer. The decorative panel covering of the present invention is a decorative panel covering with excellent surface heat resistance, printing clarity and fidelity, because it not only uses non-foaming polyvinyl chloride resin as the base layer, but also as the base With a lightweight underlayer underneath the ply, the trim covering is lightweight so it is easy to install.

Description

[0001] References to related applications [0002] This application is based on Korean Patent Application No. 10-1999-0024426 filed on June 26, 1999 and Korean Patent Application No. 10-2000-0034772 filed on June 23, 2000, which are incorporated herein by reference. Background of the invention [0003] (a) Field of Invention [0004] The present invention relates to a decorative floor covering, and more particularly, to a decorative floor covering comprising a polyethylene terephthalate film layer in a surface layer, and a method for manufacturing the same. [0005] (b) Related technical description [0006] Since the demand for convenience and healthy functions of the living environment has increased along with the recent increase in the income level, the demand for lightweight decorative panel coverings and various functional products for ordinary residences or commercial places is increasing.
