Multi-layer wood composite flooring and manufacturing method therefor

Abstract

The invention discloses a multi-layer solid wooden compound floor board, which comprises from up to down an anti-wear layer, a decoration layer and a baseboard layer that are mutually glued. The baseboard layer comprises a plurality of mutually-glued single boards. The invention additionally discloses the method for making the floor board. The method comprises: selecting a plurality layers of single boards, coating glue on them, pressing the single boards to form the baseboard layer; coating glue between the baseboard layer and the decoration layer; pressing the decoration layer and the baseboard layer; sticking the anti-wear layer on the decoration layer; finally pressing the anti-wear layer, decoration layer and the baseboard layer to form a multi-layer solid wooden compound floor board. The multi-layer solid wooden compound floor board made by above method is furnished with appearance of a solid wood floorboard, is of steady structure, not liable to deformation, is of high surface strength, is wear and scraping proof, resistant to impact, burning and contamination, and is environmental friendly; the floorboard can be applicable for different environments, is economic, practical and durable.

Description

technical field [0001] The invention relates to a floor and a manufacturing method thereof, in particular to a multi-layer solid wood composite floor and a manufacturing method thereof. Background technique [0002] Floors on the market are roughly divided into solid wood flooring, multi-layer solid wood composite flooring and laminated composite flooring. [0003] Among them, solid wood flooring is natural and woody, but raw materials are in short supply, expensive and easy to deform. [0004] The existing multi-layer solid wood composite floor has a criss-cross structure, good stability, and is not easy to deform when it absorbs water and moisture. The surface layer often needs to use thicker high-quality wood. Since the high-quality wood on the surface is thicker, it can only be obtained by cutting with a saw blade when cutting the wood, resulting in waste of wood due to sawing gaps. [0005] Laminate flooring is generally composed of a base material layer, a decorative...

[0003] Among them, solid wood flooring is natural and woody, but raw materials are in short supply, expensive and easy to deform

[0004] The existing multi-layer solid wood composite floor has a criss-cross structure, good stability, and is not easy to deform when it absorbs water and moisture. The surface layer often needs to use thicker high-quality wood. Since the high-quality wood on the surface is thicker, it can only be obtained by cutting with a saw blade when cutting the wood, resulting in waste of wood due to sawing gaps.

[0005] Laminate flooring is generally composed of a base material layer, a decorative layer and a surface wear-resistant layer. The surface strength is high, wear-resistant, scratch-resistant, and burn-resistant. However, the base layer is generally made of wood chips or wood bran mixed with glue. Its water resistance is poor, it is easy to be swelled by moisture, and it is distorted and deformed. It is only suitable for dry areas and has certain limitations.
