Description

How to form natural patterns on wood surfaces

The present invention relates to a method of forming a natural pattern on the surface of the wood, and more particularly to the surface of wooden household goods such as furniture, desks, dining tables, as well as building finishing materials such as flooring, wall materials, ceiling materials, etc. By simply forming a natural pattern such as the leaves of various flowers or plants existing in the natural world, the present invention relates to a pattern forming method that can give a beautiful natural appearance to the surface of the building finishing material or wooden household goods.

There is a growing interest in improving the quality of life as the industry develops and as a result, life is enriched. In order to meet this trend, most modern people living in barren urban environment want to change their living environment to be environmentally friendly to feel the breath of Mother Nature. As part of such means, it is common to plant pots indoors or plant trees in the garden, and the tendency to dry indoor floors and the like with wood is gradually increasing when building a house.

Flooring materials made of natural materials have the marketability as much as the number of buildings due to the recent environmentally friendly residential tendency. Usually, the flooring material using the solid wood is constructed by the slope projection (= fitting) that is commonly used around the world. In other words, the unit board is made by adhering the veneer on the square veneer plywood cut to a certain size, and forming projections on two sides of the veneer plywood and grooves into which the projections of the other veneer plywood are fitted on the other two sides. Construct them in succession. On the other hand, the width of the wood is long and the length is long, so that the unit boards are formed by continuously forming the grooves on which one of the two long sides forms a protrusion and the other on which the protrusion of the veneer plywood is fitted. Sometimes.

On the other hand, the conventional flooring flooring as described above is put a variety of patterns for the beautiful aesthetics. For example, a wood grain pattern is formed on the top veneer of each unit plate to be continuously assembled and constructed, or various patterns and the like are engraved on the top plate using a synthetic resin solution by high frequency bonding or thermal bonding. Put it in. Thereafter, the unit boards are successively assembled so that the patterns of the unit boards match properly, thereby forming a desired overall pattern on the floor covering. However, in such a case, since the individual unit boards have to be finely fitted to fit the entire pattern, work is difficult and labor time and labor are consumed a lot.

Alternatively, a desired pattern may be formed on the flooring flooring by drawing a whole pattern and then attaching a cover sheet made by coloring the adhesive sheet onto the top surface of the flooring flooring constructed on the building floor. However, in this case, the adhesive applied between the flooring and the cover sheet may float during heating after construction, and the overall height may be disturbed due to a gap due to shrinkage and expansion of wood.

On the other hand, wooden household goods such as furniture, desks, dining tables, etc., when used for a long time, the surface is often damaged and can no longer be used. Thus, there is a need to properly repair damaged surfaces. In addition, the user may be tired of the appearance of the furniture, desk, dining table and the like and want to repair or replace it. In this case, conventionally used after painting the surface of the furniture, desk, dining table, etc., at this time, there was a disadvantage that the aesthetics compared to the original product.

The present invention has been made to solve the above-mentioned conventional problems, the first object of the present invention, various types of natural present on the surface of the building finishing materials such as flooring flooring, wall materials, ceiling materials made using wood By simply forming natural patterns such as flowers or leaves of plants, wood can reduce the manufacturing cost and labor of construction finishing materials, shorten construction time on site, and give a beautiful natural appearance to the surface of the construction finishing materials. It is to provide a method of forming a pattern on the surface.

In addition, the second object of the present invention by simply forming a natural pattern, such as the leaves of various flowers or plants existing in the natural world on the surface of wooden household goods such as furniture, desks, dining tables made of wood, It is to provide a method of forming a pattern on the surface of the wood that can give the surface of the article a splendid natural appearance and extend its useful life.

Hereinafter, the method of forming a natural pattern on the surface of wood will be described in more detail.

Example 1

In order to form natural patterns such as leaves of various flowers or plants on the surface of building finishing materials such as flooring, walling, and ceiling materials, first the wood is processed to a desired size and thickness. At this time, in the present invention, instead of the conventional slice method to turn in the longitudinal direction of the wood, the wood is processed using a rotary processing method. In other words, cutting is performed while the solid wood is rotated in the axial direction.

Next, a plurality of rotary milled woods are stacked horizontally, and an adhesive such as EVA is applied therebetween to make plywood. The plywood made in this way is inserted into the press to apply strength to 500t under a temperature of 150 ~ 200 ℃ to increase the strength and eliminate the deformation of the wood. As a result, multiple logs are joined together to form a single plywood.

The phenolic resin or unsaturated resin is then coated onto the pressurized plywood, or the pressurized plywood is placed in a vacuum impregnator to remove air from the plywood and the phenolic or unsaturated resin penetrates into the plywood. Alternatively, the coating or penetrating process of the phenol resin or the unsaturated resin may be omitted.

Next, a natural pattern is engraved on the upper surface of the plywood. To this end, first, various petals or leaves are collected from nature and dried first to remove moisture. After that, color the petals or leaves according to their natural color and dry them secondarily.

After the petals or leaves are provided to provide a natural pattern, they are placed on the upper surface of the plywood reinforced by the coating or penetration of phenolic or unsaturated resins and then coated with a synthetic film, preferably polyethylene film, into the press. Insert and apply a pressure of 500t at a temperature of 150-200 캜. The result is a plywood engraved with natural patterns.

Example 2

In order to form a natural pattern such as the leaves of various flowers or plants on the surface of the wooden household goods such as furniture, desks and tables made of wood, first, after collecting various petals or leaves from nature as in Example 1 Dry first to remove moisture. After that, color the petals or leaves according to their natural color and dry them secondarily.

After the petals or leaves are provided to provide a natural pattern, they are placed on the upper surface of the wooden daily necessities to form a pattern on the surface, and then a synthetic resin film, preferably a polyethylene film is applied, and then inserted into a press machine to be 150-200. A pressure of 500 t is applied at a temperature of ° C. As a result, natural patterns are engraved on the surface of the wooden household goods.

As mentioned above, according to the present invention, instead of the conventional slice method, the wood is processed by rotary processing method and then plywood, reinforced by coating or penetration of phenol resin or unsaturated resin, and on the top surface of the reinforced plywood. Natural materials such as petals or leaves prepared by drying and coloring are placed in advance, and then polyethylene film is applied and pressed by a press to easily form natural patterns on the surface of the plywood. As a result, not only the manufacturing cost and labor of the building finishing material can be reduced, but also the construction time of the site can be shortened. In addition, it is possible to obtain a building finish having a beautiful natural appearance.

In addition, according to the present invention, after applying the polyethylene film after placing the dried and painted petals or leaves on the surface of the wooden household goods such as furniture, desk, dining table, etc., which have a damaged surface coating or worn paint in a long time at home After pressing by pressing machine to form a natural pattern. As a result, the beautiful natural appearance can be provided on the surface of the wooden household goods. In addition, it is possible to recycle wood household goods, so that the service life can be extended.
