Flooring having surface layer of synthetic resin and wood-based board
Disclosed herein is a flooring comprising a surface layer made of a synthetic resin, and a wood-based board as a base. Preferably, the surface layer includes a printed layer formed by general gravure, transfer, heat-sublimation, silk screen or digital printing using a printer, a protective made of a synthetic resin, and a UV-curable or heat-curable surface treatment layer. The wood-based board is selected from plywood, medium-density fiberboard (MDF), high-density fiberboard (HDF), particle board, and resin-wood flour composite board. The flooring may further comprise a bottom layer laminated under the wood-based board for protecting the flooring against moisture from the bottom. The flooring is cut into pieces having an appropriate size, and the pieces are processed into a finished product in a tongue and groove (T & G) shape.
1. A flooring comprising a wood-based board as a base, a bottom layer laminated under the wood-based board, and a surface layer laminated on the wood-based board,
wherein the surface layer includes a printed layer, a protective layer and a surface treatment layer;
the protective layer has a composition comprising 10˜50 parts by weight of a ethylene vinyl acetate (EVA), and 100 parts by weight of glycol-modified polyethylene terephthalate (PETG), and
the printed layer and the bottom layer are made of glycol-modified polyethylene terephthalate (PETG).
2. The flooring according to claim 1 , wherein the printed layer consists of a base layer for printing made of a synthetic resin and a printed surface formed on the base layer.
3. The flooring according to claim 1 , wherein the printed layer is formed of a printed paper or a resin-impregnated printed paper obtained by printing a paper and impregnating the printed paper with a synthetic resin.
4. The flooring according to claim 1 , wherein the printed layer consists of a glass fiber layer formed by impregnating a glass fiber sheet with a synthetic resin, a base layer for printing made of a synthetic resin laminated on the glass fiber layer, and a printed surface formed on the base layer.
5. The flooring according to claim 1 , wherein the wood-based board is at least one board selected from a waterproof plywood, a medium-density fiberboard (MDF), a high-density fiberboard (HDF), a particle board, or a resin-wood flour composite board.
6. The flooring according to claim 1 , wherein the flooring is processed into a tongue and groove (T & G) shape.
7. The flooring according to claim 1 , wherein the surface layer is embossed.
8. A flooring comprising a wood-based board as a base, a bottom layer laminated under the wood-based board, and a surface layer laminated on the wood-based board,
wherein the surface layer includes a printed layer, a protective layer and a surface treatment layer;
the protective layer has a composition comprising 30 parts by weight of ethylene vinyl acetate (EVA) and 100 parts by weight of glycol-modified polyethylene terephthalate (PETG); and
the printed layer and the bottom layer are made of glycol-modified polyethylene terephthalate (PETG).
