Preparation method for mortar and carbonized wood composite floor

Abstract

A preparation method of mortar carbonized wood composite floor. The preparation of carbonized wood needs to put the billet into the superheated steam box for multiple infiltration treatment, then carry out the phenolic resin modification treatment, and finally carry out the carbonization treatment twice, and put it into the Carbonized wood can be obtained after modification in a vacuum heating container filled with phenolic resin; after the mortar is prepared, it is poured into a special floor molding mold and smoothed, and the mold is used to form a floor heating positioning groove on the lower surface of the mortar layer , the distribution groove of carbonized wood is formed on the upper surface; then the prepared carbonized wood is placed in the distribution groove, after demoulding, curing and drying, the upper surface is polished, and then sprayed with a layer of coating containing SiO2 nano-reinforced material for protection. Mortar carbonized wood composite flooring can be obtained. The invention can solve the problems of non-solid wood flooring such as hardness, poor foot feeling, low comfort, and slow heat conduction, and the problems of easy syneresis, deformation and cracking of solid wood flooring applied to floor heating.

Description

technical field [0001] The invention relates to the field of wood processing, and mainly relates to a method for preparing a mortar carbonized wood composite floor. 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.

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
