Embodiment

[0069] In an internal mixer, 100 parts by weight of polylactic acid resin, 25 parts by weight of acetyl tributyl citrate, 10 parts by weight of acrylate monomer, 1 part by weight of dialkyl peroxide and stearic acid were mixed at a temperature of 150°C. 5 parts by weight were kneaded so that the thermally induced crosslinking reaction was sufficiently carried out.

[0070] The raw materials kneaded in the internal mixer were mixed for the first time and the second time by using a two-roll machine at 140°C.

[0071] The mixed raw materials were calendered at a temperature of 130° C. to prepare sheet samples for floor materials having a thickness of 0.4 mm, and the sheet samples were processed in a stacked manner.

[0072] At this time, the lamination process is performed by a heating roller and an embossing device using a heated steam heat source, and generally, as in the lamination process of polyvinyl chloride sheets, thermal plywood is performed under the condition of a heat...

Abstract

Disclosed is an environmentally-friendly sheet using a PLA (Polylactic acid) resin. The environmentally-friendly sheet using the PLA resin according to the present invention comprises: a back layer; a printed layer which is formed on the upper part of the back layer, wherein a printing pattern is formed on the upper surface thereof; and a transparent layer formed on the upper part of the printed layer, wherein one or more of the back layer, the printed layer, and the transparent layer have the PLA resin.

Description

technical field [0001] The present invention relates to a multi-layered sheet, and more specifically, relates to modification of the biodegradable resin by heat-induced crosslinking reaction while at least one layer constituting the eco-friendly sheet is formed of a biodegradable resin containing a polylactic acid resin , so that it is easy to process and has excellent mechanical and physical properties after processing. It is an environmentally friendly sheet made of polylactic acid resin. Background technique [0002] Sheets made of petroleum resin such as polyvinyl chloride (PVC) are widely used in buildings such as houses, buildings, apartments, offices, and shops. [0003] Such a sheet is produced by extrusion or calendering using a resin such as polyvinyl chloride. However, since the raw materials are all derived from crude oil, which is a finite resource, it is expected that problems such as supply and demand of raw materials will arise in the future due to the deple...
