Micro-carbonization method for solid wood floor

Abstract

The invention discloses a micro-carbonization method for a solid wood floor. The micro-carbonization method includes: cutting to obtain a solid wood floor slab, standing and drying the solid wood floor slab in a vacuum environment of 60-80 DEG C for 60-90 minutes, wherein the excess pressure of the vacuum environment is 0-9KPa; performing microwave drying to allow the water content of the solid wood floor slab to lower to below 6%; rising the temperature to 160-200 DEG C in a humidified environment in a carbonization chamber to perform carbonization; after the carbonization, transferring the solid wood floor slab to a vacuum environment of 60-80 DEG C, and standing for 30-45 minutes; soaking into paraffin liquid for 45-60 seconds, and taking out. By the micro-carbonization method, the obtained micro-carbonized solid wood floor is dampproof, mothproof, corrosion-resistant, stable in performance, uniform in carbonization and good in mechanical performance such as bending strength, impacttoughness and nail-holding ability, and the usability of the micro-carbonized solid wood floor is increased.

Description

Technical field [0001] The invention relates to a method for micro-carbonization of solid wood flooring. Background technique [0002] With the continuous improvement of people's living standards and the increasing awareness of environmental protection, people not only require the floor to have basic characteristics such as waterproof, moisture-proof, and anti-cracking, but also hope that the floor will not release harmful substances, and the color of the floor will be more natural. Because solid wood flooring has natural and beautiful texture and comfortable feet, it maintains the best microenvironmental characteristics of natural wood, making solid wood flooring the first choice for people's home decoration and floor covering materials. The existing floors are generally made of wood or bamboo. In order to ensure the structural strength of the entire floor, all floors are made by pressing wood or bamboo using a press to form a high-density and high-strength floor. However, suc...

Therefore, carbonized wood is more and more favored by people. However, the existing wood carbonization is mainly through putting the wood in a large cylinder in time, and then heating the bottom. This carbonization process can only carbonize the surface of the wood and cannot Deep carbonization of wood will cause the wood to swell or deform and crack after being used for a long time. The invention patent with application number 201610462127.4 discloses a method of deep carbonization of wood, but the carbonized wood produced by this method is suitable for outdoor use. Environment, for solid wood flooring, this method of carbonization is not applicable, the uniformity of carbonization is poor, and the density of the solid wood floor after treatment is reduced, and some mechanical properties will also be reduced, such as the floor’s flexural strength, impact toughness and The nail-holding force is significantly reduced, which affects the performance of the floor
