Problems solved by technology

[0002] Poplar is a very good renewable raw material. However, the material of poplar is poor. If it is used directly without modification, it is difficult to achieve the inherent physical and mechanical properties of high-quality wood.
Due to the above reasons, the existing poplar floors are all made of poplar and other wood composites, and there is no pure poplar floor

Embodiment 1

[0024] (1) Cut off the poplar logs, cook them, peel them off, cut them into poplar veneers, and dry them to ensure that the moisture content of the poplar veneers after drying is 8%, and the thickness of the surface veneers must be 2.0MM, as a paint surface, The thickness of other layers of veneer is 1.0MM;

[0025] (2) The poplar veneer is impregnated with resin. Put the poplar veneer into the vacuum kettle, evacuate to 1500Pa, and keep it for 1 hour; then the prepared MF impregnation solution with a concentration of 50% by weight (solid content 80%, pH 8.2-9.7, viscosity 700- 1100mPa.s, the grade is Sumirez? Resin 613, melamine formaldehyde resin glue solution l000ml manufactured by Sumitomo Chemical Industry Co., Ltd. is prepared by adding distilled water 600ml) into the container in the vacuum kettle, and the poplar veneer is required to be completely immersed in the impregnating solution , and then soaked for 1 hour under vacuum. After slowly degassing, take out...

Abstract

The invention relates to full-poplar multilayer engineered solid wood flooring and a production method thereof. The full-poplar multilayer engineered solid wood flooring is characterized by being formed by bonding multiple layers of single poplar boards, wherein the resin impregnating treatment is carried out on the single poplar boards; and resins used in the resin impregnating treatment are melamio-formaldehyde resins. The production method of the full-poplar multilayer engineered solid wood flooring comprises the following steps of: drying, splicing, gluing, assembling and hotly pressing the single poplar boards so as to obtain a full-poplar multilayer plywood; and making the full-poplar multilayer plywood into the engineered solid wood flooring; and the production method of the full-poplar multilayer engineered solid wood flooring is characterized in that the resin impregnating treatment is carried out on the dried single poplar boards between the drying step and the splicing step; and the resins used in the resin impregnating treatment are the melamino-formaldehyde resins. The full-poplar multilayer engineered solid wood flooring provided by the invention has the advantages of uniform structure, high strength and good dimensional stability.

Description

technical field [0001] The invention relates to a whole poplar multi-layer solid wood composite floor and a production method thereof. Background technique [0002] Poplar is a very good renewable raw material. However, the material of poplar is poor. If it is used directly without modification, it is difficult to achieve the inherent physical and mechanical properties of high-quality wood. Due to the above reasons, existing poplar flooring is all made of poplar and other wood composites, and there is no pure poplar flooring. Contents of the invention [0003] The object of the present invention is to provide a full poplar multi-layer solid wood composite floor with uniform structure and stable size and a production method thereof. [0004] In order to achieve the above object, the present invention provides a full poplar multi-layer solid wood composite floor, which is characterized in that it is formed by bonding multi-layer poplar veneers, and the poplar veneers are tr...
