Definitions
- the present invention relates to a decorative sheet. More specifically, the present invention relates to a polyethylene terephthalate glycol (PETG)-based decorative sheet with formability comparable to polyvinylchloride (PVC).
- PETG polyethylene terephthalate glycol
- PVC polyvinylchloride
- PETG decorative sheets for forming-purposes exhibit superior surface quality, but have a narrow range of high forming temperatures, as compared to polyvinylchloride (PVC). That is to say, in spite of superior surface quality and formability, PETG decorative sheets have a narrow range of forming temperature, thus making it difficult to perform secondary subsequent processing (i.e. forming). At low forming temperatures, the edge of articles may be cracked, or the adhesion force of the articles may be deteriorated. At high forming temperatures, there are problems in that the edges of articles may droop or sag, and surface quality is deteriorated in proportion to forming quality.
- Japanese Patent Laid-open Publication No. 2003-246916 discloses a composition for a flexible cosmetic polyester sheet having a specific melt volume- flow rate, comprising a specific mix ratio of three polyester resins that differ from one another in glass transition temperature.
- No. 2005-298715 discloses a composition with flame-retardancy employing the flexible polyester sheet and inorganic filler. Such prior art is different from the present invention that aims to lower forming temperatures at which a PETG resin is available and widen the range thereof.
- a decorative sheet comprising a polyethylene terephthalate glycol (PETG) alloy resin prepared by alloying a PETG resin with an ester resin or an elastomer resin.
- the PETG alloy resin of the present invention has a glass transition temperature (Tg) of 75 ⁇ 3 0 C which is lower than that of a general PETG resin by 3 to 7°C; and therefore, it is applicable to forming processes at low temperatures similar to those of PVC.
- the PETG alloy resin of the present invention is applicable to forming processes at 60 to 80 0 C. This range is wide, similar to that of PVC.
- PETG resins are generally applicable to forming processes at 7O 0 C to 85 0 C.
- the ester resin used as the alloy ingredient in the present invention is polybutylene terephthalate (PBT) and may be prepared by liquid- or solid polymerization.
- the elastomer resin used in the present invention may be a copolymer of a PBT resin and polyether glycol.
- the content of the ester resin or the elastomer resin may be 5 to 20 parts by weight, based on 100 parts by weight of the PETG.
- Tg and forming temperature of the alloy resin cannot be lowered to a desired level.
- Tg and forming temperature of the alloy resin are excessively low, compound-property and sheet-extrudability are deteriorated and sheet-processibility is thus degraded due to characteristics of PBT and elastomer resins during processing. At this time, due to resistant-chemical properties of the PBT resin, surface-processibility and adhesion force of sheets are deteriorated.
- the PETG resin by alloying the PETG resin with an ester resin or elastomer resin and thus lowering Tg by 3 to 7°C and gradually sloping down the decreasing rate of elastic modulus, it is possible to prepare a compound having thermal behaviors similar to PVC.
- decorative sheets applicable to forming processes in a wide range of low temperatures may be prepared from this compound.
- one of representative methods for evaluating the formability is to measure variation in elastic modulus employing dynamic mechanical analysis (DMA).
- DMA dynamic mechanical analysis
- FIG. 1 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 1 ;
- FIG. 2 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 2;
- FIG. 3 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 3;
- FIG. 4 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 4; and FIG. 5 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Comparative Example.
- a PETG resin was subjected to extrusion-sheeting in a thickness of 0.5 mm.
- the glass transition temperature of a conventional PETG mirrored decorative sheet begins to decrease at around 74°C and is then minimized at around 84 0 C.
- FIG. 1 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 1 (PETG + PBT alloy resin, content of alloy ingredient: 10 phr). As apparent from FIG. 1, Tg is 76°C and storage modulus begins to decrease at 65 0 C.
- FIG. 2 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 2 (PETG + PBT alloy resin, content of alloy ingredient: 20 phr). As apparent from FIG. 2, Tg is 74°C and storage modulus begins to decrease at 63 0 C.
- FIG. 3 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 3 (PETG + PBT copolymer elastomer alloy resin, content of alloy ingredient: 10 phr). As apparent from FIG. 3, Tg is 77°C and storage modulus begins to decrease at 65 0 C.
- FIG. 4 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Example 4 (PETG + PBT copolymer elastomer alloy resin, content of alloy ingredient: 20 phr). As apparent from FIG. 4, Tg is 73 °C and storage modulus begins to decrease at 6O 0 C.
- FIG. 5 is a graph showing variations in glass transition temperature and storage modulus of a decorative sheet according to Comparative Example (PETG resin). As apparent from FIG. 5, Tg is 83 0 C and storage modulus begins to decrease at 73°C.
