Problems solved by technology

[0002] Decorative sheets based on polyethylene-tere-phenylene glycol (PETG) for molding purposes show excellent surface properties compared to polyvinyl chloride (PVC), but have high molding temperatures in a narrow range
[0003] That is, although the PETG decorative sheet has excellent surface quality and easy formability, it has a narrow range of forming temperature, thereby making it difficult to perform secondary post-processing (ie, forming)
At low molding temperatures, the edges of the product may crack, or the adhesion of the product may deteriorate
At high molding temperatures, problems arise in that the edges of the product may sag or sag, and the surface quality deteriorates in proportion to the molding quality

Abstract

Disclosed herein is a polyethylene terephthalate glycol (PETG)-based decorative sheet with formability similar to polyvinylchloride (PVC). The decorative sheet comprises a polyethylene terephthalate glycol (PETG) alloy resin prepared by alloying a PETG resin with an ester resin or an elastomer resin.

Description

technical field [0001] The invention relates to a decorative board. More particularly, the present invention relates to a decorative board based on polyethylene terephthalate glycol (PETG) having a formability comparable to that of polyvinyl chloride (PVC). Background technique [0002] Decorative sheets based on polyethylene-tere-phenylethylene glycol (PETG) for molding purposes exhibit excellent surface properties compared to polyvinyl chloride (PVC), but have high molding temperatures in a narrow range. [0003] That is, although the PETG decorative sheet has excellent surface quality and easy formability, it has a narrow range of forming temperature, thereby making secondary post-processing (ie, forming) difficult. At a low molding temperature, the edges of the product may crack, or the adhesive force of the product may deteriorate. At high molding temperatures, problems arise in that the edges of the product may sag or sag, and the surface quality deteriorates in prop...
