preparation example

[0118] Preparation of transparent layer

[0119] Using an extruder, 100 parts by weight of polylactic acid resin 2002D (manufactured by Natli Vox (Nature Works), melt index: less than 3), 20 parts by weight of acetyl tributyl citrate, 10 parts by weight of Acrylic acid copolymer, 5 parts by weight of stearic acid, and 5 parts by weight of carbodiimide were kneaded for the first time, and after kneading at 140°C using an internal mixer, they were mixed for the first time using two rollers at 140°C. Mix a second time. Thereafter, the prepared raw material was calendered at a temperature of 130° C. to prepare a sheet with a thickness of about 0.6 mm.

[0120] Preparation of printing layer

[0121] Through the same process as the above-mentioned transparent layer preparation process, for 100 parts by weight of 2002D, 30 parts by weight of acetyl tributyl citrate, 10 parts by weight of acrylic acid copolymer, 5 parts by weight of stearic acid, 5 parts by weight of di Isocyanate,...

Abstract

The present invention relates to a board complex having a polylactic acid (PLA) cover. The board complex comprises: a cover member having at least one layer containing a PLA resin; and a board formed beneath the cover member, wherein the material for the board is selected from a medium-density fibreboard (MDF), plywood, an asbestos-free cellulose fiber reinforced cement board, a magnesium board, glued laminated timber, a high density fiberboard (HDF), a particle board, ceramic tile, porcelain tile, a ceramic board and a click-fastened board.

Description

technical field [0001] The present invention relates to a board complex having a PLA cover, and relates to a technique for forming a board complex using polylactic acid, which is an environment-friendly resin. Background technique [0002] As flooring materials used in buildings such as houses, mansions, apartments, offices, and shops, flooring materials based on petroleum-based resins such as polyvinyl chloride (PVC) are mainly used. [0003] The above-mentioned floor materials using polyvinyl chloride and the like are prepared by extrusion or calendering using polyvinyl chloride (PVC) and other resins. However, since the raw material of polyvinyl chloride resin is based on petroleum resources, there may be serious problems in the supply and demand of raw materials in the future due to the depletion of petroleum resources. [0004] Moreover, polyvinyl chloride (PVC) floor materials produce a large amount of harmful substances when they are used or discarded, so it is neces...
