Problems solved by technology

Solid wood flooring is the most environmentally friendly flooring, but there are problems such as poor deformation resistance, warping resistance, inability to use small secondary materials, and low material utilization.
Laminate flooring is not strong in wood, and the amount of adhesive is large. In addition, many domestic enterprises do not process it properly, and it is easy to produce a large amount of formaldehyde, causing indoor environmental pollution. If formaldehyde-free glue is used, the cost will increase. Compared with the other two types of flooring Compared with its cost performance, it will lose its advantage, and its market share is decreasing year by year
Because solid wood multi-layer composite flooring uses a large amount of adhesives in its manufacture, it is also easy to generate a large amount of formaldehyde in the laminate flooring, causing indoor environmental pollution. If formaldehyde-free glue is used, the cost is extremely high, and the investment in equipment is huge, so it is not easy to have considerable development

Abstract

The invention relates to a novel bamboo and wooden structure floor. A core layer made of non-wooden material is arranged between a bamboo surface layer and a solid wood layer, and a solid wood middle layer is arranged in the middle of the core layer made of non-wooden material. The core layer is made of artificial fibre or artificial fibre fabric, natural fiber or natural fiber fabric, synthetic fiber fabric, etc. The loading is 10-440g / m2 and the thickness is 0.1-2mm. With the non-wooden material filled between the bamboo layer and the solid wood layer, the invention improves the strength and the deformation resistance of the floor, and is provided with funny and beautiful texture, natural and true elasticity.

Description

technical field [0001] The invention relates to a floor, in particular to a bamboo-wood structure floor formed by adding non-wood materials between bamboo and solid wood layers and pressing. Background technique [0002] With the improvement of people's living standards and the development of the real estate industry, people's requirements for interior decoration floor materials are getting higher and higher. Because the floor can meet people's requirements for returning to nature, moisture-proof, heat preservation and indoor environmental protection, it is widely used in residential houses and high-end hotels. It is widely used in the decoration of public places such as apartments, office buildings, hotels and entertainment, and the demand for flooring is increasing year by year. At present, the floors provided on the market include: solid wood flooring, laminate flooring, solid wood composite flooring (also can be divided into solid wood three-layer, solid wood multi-layer...
