Flooring having PLA layer

Abstract

Disclosed therein is a flooring, which can secure environment-friendliness by forming a surface layer laminated on an upper face of a base layer using PLA (Poly Lactic Acid) resin instead of wood, easily provide a handcraft surface texture by applying a curved pattern onto the surface of the surface layer using embossing rollers at the time that the surface layer is manufactured, and prevent compression, scratches, discoloration, and so on in comparison with woods. The flooring constructed on a floor of a building includes: a base layer (110) made from one of an MDF, an HDF, and a plywood; and a surface layer (130) having a reinforced layer (131), a printed layer (133), and a transparent layer (135) which are laminated on an upper face of the base layer (110) in order, at least one of the layers being made of PLA (Poly Lactic Acid) resin. A curved pattern (137) is formed on an upper face of the surface layer (130).

Description

technical field [0001] The present invention relates to a floor, and more particularly, to a floor that can easily provide handcrafted effects to enhance the natural surface texture of the floor and is resistant to crushing, scratching, discoloration, and the like. Background technique [0002] In general, floors are laid to cover and decorate concrete surfaces laid on the interior floors of buildings, thereby presenting a high-end interior environment and providing the effect of natural wood texture. [0003] With the development of plywood production technology, the use of hardwood has increased, and various plywood with good properties can be provided. Plywood is produced by thinning the hardwood, rather than cutting it directly into logs or boards; cutting the veneers; laminating the veneers so that the grains of the wood are at right angles to each other; bonding the veneers with an adhesive to form Board body of predetermined thickness. [0004] The plywood produced ...

AI Technical Summary

Problems solved by technology

[0006] As an example of the production method of the floor, there is a method of producing a floor by bonding a decorative veneer on the upper surface of a plywood using a urea resin to produce a board, but the board production method has disadvantages in that, Increased production costs and very poor water and heat resistance

[0007] Also, flooring using wood can provide handmade effects to ensure authenticity, but it is difficult to ensure productivity because the handmade effects are achieved through manual labor

In particular, wood boards present several problems in that it is difficult to present a handcrafted effect using commonly used 0.5 mm flush-cut veneers and in that production costs increase because at least 2 mm of hardwood is used
