Solid wood composite cork floor and making method thereof

Abstract

The invention belongs to the technical field of wood floor, relates to a solid wood composite floor, and particularly relates to a solid wood composite cork floor and a making method thereof. The solid wood composite cork floor disclosed by the invention sequentially comprises a coating layer, an upper cork composite layer, an upper balancing layer, a middle layer, a lower balancing layer and a lower cork layer, wherein a solid wood composite material layer is arranged between the upper and lower cork layers, the lower surface of the coating layer is laminated to the upper surface of the uppercork layer, the lower surface of the upper cork layer is laminated to the upper surface of the upper balancing layer, the lower surface of the upper balancing layer is laminated to the upper surfaceof the middle layer, the lower surface of the middle layer is laminated to the upper surface of the lower balancing layer, and the lower balancing layer is laminated to the upper surface of the lowercork layer. The invention also discloses a making method of the floor. The invention solves the characteristic of easy deformation of solid wood, overcomes relatively poor mechanical property of cork,adopts a gluing manner of two times of assembly, and effectively solves the problems of poor quality and poor gluing property caused by deformation, lamination dislocation and compression performancedifference of different layers.

Description

technical field [0001] The invention belongs to the technical field of wood flooring, and relates to solid wood composite flooring, in particular to a solid wood composite cork flooring and a manufacturing method thereof. Background technique [0002] Existing all kinds of wood or the floor made by processing wood as the main raw material are generally welcomed by consumers because of their superior physical properties. However, in some special applications, such as quiet conference rooms, high-end cinemas and concert halls, and children's activity places, in order to avoid noise or protect infants and young children, people have to use expensive, difficult-to-clean carpets or poor wear resistance. , Easy to scratch, poor stability and deformation of the cork floor. [0003] Cork is a renewable forest resource. Cork flooring has the characteristics of health, softness, comfort, good foot feel, and anti-fatigue. Reasonable and other advantages, more and more popular. [00...

AI Technical Summary

Problems solved by technology

[0004] The existing cork composite flooring is made of MDF as the base material. It retains some characteristics and performance of cork flooring, and has the advantages of easy installation of laminated flooring and no damage to the ground structure. It has become a popular floor in the market. However, due to the limitations of the mechanical properties, foot feel, moisture-proof performance, and structural visual effects of the density board used, it has become the main factor that consumers worry about when purchasing.

[0005] Although the solid wood floor has a strong sense of solid wood, it is easy to warp and deform, and consumes forest resources, because most of it is made of whole wood, and the grain of solid wood materials (including bamboo materials) is unidirectional, so the performance in anti-deformation is relatively poor, making The simple combination of solid wood and cork does not function optimally

[0006] Chinese patent CN89207817.0 "cork composite flooring" discloses a very simple structure. On the surface of solid wood floor boards or medium density fiberboards or particle boards, a layer of cork chips with a thickness several times that of cork particles is pasted. This structure has poor stability and is easy to deform. And sizing pavement releases a large amount of formaldehyde

Patent CN201120030302.5 "A Cork Floor" includes a substrate layer, a wear-resistant layer is arranged above the substrate layer, a balance layer is arranged below the substrate layer, and a layer is arranged between the substrate layer and the wear-resistant layer There is a cork layer, the cork layer is made of soft wood instead of cork, and has no cork insulation, sound insulation, sound absorption, insulation, and antistatic properties
