Abstract

Provided is a decorative building material and a method of manufacturing the same, and more particularly to a decorative building material which is manufactured by a simple process and has a print layer excellent in sharpness, realism, and stereoscopic effect as well as having a functional layer such as an impact absorbing property and a manufacturing method thereof. The method of manufacturing a decorative material includes the steps of: (S1) preparing a transfer film on which a pattern is printed; (S2) preparing a substrate comprising polyvinyl chloride resin, a white film comprising polyvinyl chloride resin, and a transparent film comprising polyvinyl chloride resin; (S3) laminating the white film, the transparent film, and the transfer film on the substrate in order and at the same time performing a heat treatment under pressure; and (S4) peeling off the transfer film.

A method of manufacturing a decorative building material comprising the steps of:

preparing a transfer film on which a pattern is printed;
preparing a substrate comprising polyvinyl chloride resin, a white film comprising polyvinyl chloride resin, and a transparent film comprising polyvinyl chloride resin;
laminating the white film, the transparent film, and the transfer film on the substrate in order and at the same time performing a heat treatment under pressure;
and
peeling off the transfer film;
wherein the white film contains 10 to 20 wt % titanium based on the total weight of the white film;
wherein the substrate comprises a base layer and a balance layer, wherein the base layer comprises 100 parts by weight of polyvinyl chloride resin, 1 to 5 parts by weight of heat stabilizer, 20 to 30 parts by weight of plasticizer, 10 to 30 parts by weight of elastomer, 1 to 5 parts by weight of pigment and 200 to 300 parts by weight of filler, and the balance layer comprises 100 parts by weight of polyvinyl chloride resin, 1 to 5 parts by weight of heat stabilizer, 15 to 20 parts by weight of plasticizer, 1 to 5 parts by weight of pigment and 100 to 150 parts by weight of filler;
and
wherein the filler comprises at least one selected from the group consisting of calcium carbonate, calcium sulfate and silica;
and the elastomer comprises at least one selected from the group consisting of nitrile butadiene rubber (NBR), ethylene vinyl acetate (EVA), and styrene butadiene rubber (SBR).
