Ocher floorboard manufacturing method {Method for manufacturing flooring board of loess}

The present invention relates to a method for manufacturing flooring material (floor material), and more specifically, the surface of the plywood using the liquid ocher and thermosetting melamine resin, but the liquid ocher and Impregnating and thermosetting the impregnated liquid mixed with thermosetting melamine resin not only improves the durability of the floorboard material, but also enables the formation of excellent surface and pattern, and in particular, the human body due to various components obtained from ocher It relates to a loess floorboard manufacturing method that can be obtained such as environmentally friendly floorboard material.

In general, it is common to decorate the interior by decorating the interior surface or wall with various forms of cardboard or wallpaper to decorate the concrete surface. However, in recent years, the living culture is also improved by improving living standards. In order to upscale the interior and to have a natural wood texture throughout the living space, constructions that express wood texture of wood by attaching a separate floor board or attaching to the floor of the interior are becoming common.

These floorboards are mainly used in the living room floor of apartments, detached houses, or indoor floors of offices and schools in order to create an environment-friendly environment, and floorboards typically include reinforced floors such as Patent Application Publication No. 10-2007-0053845. And wood floors such as Japanese Patent Application Laid-Open No. 10-2011-0059137.

Here, the reinforced floor is manufactured by coating a chemical melamine film having a solid wood pattern on the basis of a high-density fiberboard (HDF) that is finely crushed wood and mixed and compressed with an adhesive.

However, such reinforced floors are usually spaced apart from the bottom surface, so the thermal conductivity is very low, and is sensitive to moisture, so it is easy to be deformed, such as shrinkage expansion. However, this was a serious problem causing respiratory diseases due to the inflow and accumulation of foreign matters such as dust into the gap, especially, the surface layer has a problem that the texture of the surface is coated with an artificial film finish.

In addition, solid wood flooring is a floor processed using natural wood as it is, is produced by coating the surface while keeping the natural wood pattern of the surface as it is.

However, the wood floor as described above, the price is higher than other floorboards, it is not suitable for use as a popular type, there is a disadvantage that the durability is poor, such as weak to impact because no additional reinforcement work is performed, long-term moisture There was a problem that deformation easily occurs during exposure and drying.

In addition, steel floor using plywood is used, such steel floor is produced by attaching a melamine film on the surface of the plywood.

However, the steel floor as described above has a problem that the durability is remarkably deteriorated, such as shrinkage and expansion due to a large number of voids formed in the surface layer of the plywood and deformation occurs when exposed to moisture, and artificial melamine film is applied to the surface There was a problem that the texture dropped significantly.
