Processing method of solid wood floor for underfloor heating

Abstract

A processing method for solid wood flooring for floor heating. First, the blank is placed in a superheated steam box for soaking treatment, and then the blank is placed in a vacuum heating container filled with phenolic resin for modification, and then sent into a high-temperature atmosphere furnace. The blank is subjected to two carbonization treatments: after the first carbonization treatment is completed, the blank is first placed in a saturated steam box for humidity control and moisture recovery treatment, and then a silicon carbide coating is sprayed on its lower surface, and then the second carbonization treatment is performed; finally Put it into a vacuum heating container equipped with phenolic resin and modify it again, and after sealing the paint on each surface of the blank, you can get a solid wood floor for floor heating; the solid wood floor prepared by the invention can be used for floor heating, and has anti-corrosion Insect-proof performance, does not contain any harmful substances, and has no negative impact on human body and environment.

Description

technical field [0001] The invention relates to the field of wood processing, and mainly relates to a processing method of a solid wood floor for floor heating. Background technique [0002] Solid wood flooring is the most popular mid-to-high-end product among all flooring categories. It has a comfortable foot feel, natural beauty, and has the functions of heat preservation and adjusting indoor temperature and humidity. There is no pollutant release during use. Under the background that people generally pay attention to the environment , Solid wood flooring is the first choice in home decoration. In recent years, solid wood flooring has been used more and more in floor heating environments. However, when solid wood flooring is used in floor heating, there will always be various problems. With the change of temperature and humidity, wood will evaporate or absorb water, resulting in shrinkage or swelling, resulting in the size of the wood. Unstable, causing defects such as wa...

Problems solved by technology

In recent years, solid wood flooring has been used more and more in floor heating environments. However, when solid wood flooring is used in floor heating, there will always be various problems. With the change of temperature and humidity, wood will evaporate or absorb water, resulting in shrinkage or swelling, resulting in the size of the wood. Unstable, causing defects such as warping, deformation and cracking of wood and products. Although dry wood is used for solid wood flooring, it will also be affected by changes in temperature and humidity in the atmosphere, resulting in shrinkage and swelling. The final moisture content is generally 8~12%, and the floor heating temperature is usually 50~60°C. Long-term use of floor heating will cause the water in the floor to evaporate and cause shrinkage. , seam, deformation and other defects

[0003] In order to solve the problems of syneresis, deformation and cracking of solid wood flooring, the commonly used methods are: to seal the solid wood floor with paint on six sides, but the sealed paint film is easily damaged during installation and use, thus losing its performance. , and it is not convenient for later polishing and refurbishment, there is also a heat-resistant protective coating that is coated on the outside of the base material of the solid wood floor and penetrates into the base material, and is bonded with the wood fiber to prevent the intrusion of heat into the base material, but this This method cannot effectively overcome the internal stress of wood, and cracking and deformation will still occur in a high-temperature heating environment or a humid environment for a long time. At the same time, due to the existence of a heat-resistant protective layer, the heat conduction capacity of the solid wood floor is also reduced to a certain extent. , causing the indoor temperature to rise slowly, resulting in waste of heat energy, so there is an urgent need for a good processing method of solid wood flooring for floor heating to solve the above problems
