The present invention relates to a method for manufacturing a subsidiary material for indoor interior, and more specifically, to a manufacturing method developed to improve the material and properties of a bar-shaped sub material used for decoration or any functional purpose in a room. It is about.

Interior subsidiary materials used indoors can be said to be a typical interior member that the molding member mounted on the corner between the ceiling and the wall and the baseboard mounted on the wall at the floor and the wall interface are seen in a normal home.

In the past, most of these subsidiary materials used wood, but in the case of wood, high quality wood is not used as such interior subsidiary materials due to the exhaustion of resources.

In addition, in the case of wood, the aesthetics are very good due to its unique texture, but the strength is weak, so it is easily damaged. In case of wood that is not sufficiently dried, moisture penetrates between internal tissues and causes deformation.

What is made to replace these wood is made of synthetic resin, but in this case, a large amount of toxic gas is generated in the case of fire, and above all, environmental friendliness has become a big issue in recent years, but it is not suitable for this.

In addition, there is an advantage that can be easily applied to a variety of colors and shapes, but the weakness of heat, if you adopt a floor heating like ours, there is a big disadvantage that deformation occurs due to shrinkage and expansion according to the temperature.

In addition, when manufactured in the form of a long bar, due to its unique ductility, it is difficult to construct a lot.

In addition, even the wood with a relatively specific wood texture does not have an original feeling because it is a uniform wood texture, and in the case of synthetic resins, it is difficult to express various patterns, especially marble-like patterns.

The present invention has been developed to solve the above problems, the object is to allow the surface of the subsidiary materials manufactured by using wood and synthetic resin, such as marble to obtain a pattern.

In addition, it provides a subsidiary material in the form of light and ductility and excellent durability by giving the bar-shaped member the direction and the density of the tissue.

In addition, to provide a subsidiary material that can reduce the deformation caused by heat or moisture.

In addition, it is to provide a subsidiary material that can reduce the toxic gas generated in the fire situation.

In order to achieve the above object, the present invention comprises a dyeing process of dyeing a coarse wood powder having a maximum length of at least 2mm or more in a desired color;

The coarse wood flour, fine wood flour pulverized into fine powder, and polyvinyl chloride (PVC) powder are mixed, but the fine powder and polyvinyl chloride powder are each maintained at a ratio of 20% or more of the total weight, and the polyvinyl chloride powder A mixing step of mixing the mixture so as to be constantly mixed in the heated and molten state;

A first molding process of extruding the mixture mixed in the mixing process in a molten state, and then molding the mixture into a predetermined size and shape in consideration of the ratio of compression and grinding in the process;

A secondary molding process of molding the first molded molding by compression press for a predetermined time;

It is characterized in that a series of grinding processes for grinding at least 1 mm of one side of the formed subsidiary material are continuously performed.

Alternatively, the dyeing process may be replaced by a process of directly inserting a pigment master batch having a maximum length of at least 2 mm,

The mixing process is a mixture of fine wood flour (2) and polyvinyl chloride (PVC) powder (3) pulverized into a fine powder, a master masterbatch having a maximum length of at least 2mm or more, but the fine powder (2) and polyvinyl chloride powder (3) may be replaced by a mixing process in which each of the polyvinyl chloride powders is maintained at a ratio of 20% or more of the total weight, and mixed so that the polyvinyl chloride powder is uniformly mixed in a heated and molten state.

Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

1 is a block diagram according to an embodiment of the present invention, in the case of conventional wood is made of a process such as cutting and polishing and painting, in the case of synthetic resin is completed by extrusion but the present invention is a dyeing process and mixing process And primary molding, secondary molding process and grinding process.

Figure 2 is a conceptual diagram showing a dyeing process and a mixing process of the present invention, in the dyeing process is made by dyeing the coarse wood powder (1) having a maximum length of at least 2mm or more in a desired color. At this time, less than 2mm wood flour is not preferable because the visibility of the pattern in the final result can not expect the effect of the invention.

In addition, the dyeing process may be all the same color, but can be applied to the method of adjusting so that there are some differences in consideration of the subsidiary materials to be finally completed, by varying the dyeing time rather than having a separate dye solution The method of adjustment will be easiest.

In the mixing process, the coarse wood powder (1), fine wood powder (2) pulverized into fine powder and polyvinyl chloride (PVC) powder (3) are mixed, but the fine powder (2) and polyvinyl chloride powder (3) ) Is maintained at a ratio of 20% or more of the total weight, and the polyvinyl chloride powder is mixed so as to be constantly mixed in a heated and molten state.

At this time, the sum of the coarse wood powder and fine wood powder is at least 20%, and the polyvinyl chloride powder is also mixed at least 20%. If the wood powder is less than 20%, there is no big difference from the subsidiary materials made of conventional synthetic resins. It is to solve the problem that the polyvinyl chloride powder is less than 20% in the molding process and is easily broken in the molding process when the fire is warped and no toxic gas is generated.

Therefore, while maintaining the ratio to obtain a minimum material advantage, the producer is produced by selectively adjusting the ratio in consideration of the desired characteristics.

In general, polyvinyl chloride is melted at a temperature of 170 ° C. or higher and wood is not burned at this temperature, so that the polyvinyl chloride is mixed in a mixed state so that the polyvinyl chloride is heated and uniformly mixed in a molten state. Since the case of not uniformly mixing due to the difference of using such a mixing method will be possible to uniform mixing.

In addition, the description of the primary molding process and the primary molding process will be described according to the accompanying drawings.

Figure 3 is a perspective view showing an example of the primary molding process, the primary molding process is to be molded to a predetermined size and shape in consideration of the ratio of the mixture is mixed in the mixing process.

In general, even when the polyvinyl chloride is in a molten state, the mixed wood powders 1 and 2 may be deformed by pressure when the wood powders 1 and 2 are contained in a large amount.

Therefore, if you make the frame of the shape you want to make first, and then further processing, you can improve its properties.

It is also preferred that the mixture be molded by extrusion since it is produced in the form of a long bar.

At this time, the wood flour (1, 2), even if the fine powder, but has a longer shape in the grain direction than the spherical nature due to the nature of the wood grain, such extrusion molding is molded by being extruded by pressure ) Has a shape arranged uniformly in the longitudinal direction.

According to the change of the tissue, the tissue is directional, and the property of polyvinyl chloride, which is easily bent in the longitudinal direction, can be minimized by extremely ductile wood or wood flour.

In addition, the device shown in the figure shows an extruder, when the mixture of the state is melted and fluidity is put into the extruder (4) through the hopper 41 and forcedly transferred by the screw 42 one end desired shape A long successive exit into the perforated opening 43.

The bar-shaped molding thus produced can be produced in a desired length unit by cutting the cutter 46 attached to the end of the air cylinder 45 operated by the foot pedal 44 in the middle.

Figure 4 is a perspective view showing an example of the secondary molding process of the present invention, the secondary molding process is to be molded by compression for a predetermined time by a compression press (6).

In the molding by compression, as shown in the drawing, the wood powder having a coarse texture (1, 2) is compressed so that the tissue becomes more dense, thereby improving strength and durability.

However, despite these effects, the wood flour (1, 2) is lighter weight, so the weight has the advantage over the conventional polyvinyl chloride.

In addition, the arrangement of the tissue is somewhat ductile in the longitudinal direction, but in the other direction the ductility is minimized, the overall curvature is further reduced.

At this time, the shape that is finally completed by the compression press may be to give an angle by refracting a part of the shape in the primary molding process, it is also possible to insert a pattern of various yin and yang.

In addition, in order to overcome the disadvantages of wood, such as weak in the past, the temperature of the molten polyvinyl chloride in the mixing process, such as having the surface in the iron, that is, the method of carbonizing part of the surface was used. It also has the advantage of improving the properties of wood by carbonizing the surface of long-term exposure to dust powder.

On the other hand, coarse wood flour (1) will make a significant contribution in terms of recycling of resources as it uses sawdust from wood processing companies such as woodworking shops or finely crushes separate waste wood.

Figure 5 is a perspective view showing an example of the grinding process of the present invention, Figure 6 is a conceptual diagram showing a change in the surface pattern of the wood according to the grinding process of the present invention, the grinding process of grinding at least 1mm on one side of the molded auxiliary material Indicated.

First, the grinding device 5 shows a structure of grinding one surface while rotating by a general rotary saw blade 51, but in fact, the surface attached to the wall in the interior interior does not need grinding, except that only the surface visible from the outside is ground. It would be desirable to make it.

Therefore, when the surface to be ground is not a straight line, grinding is performed by a separate grinding device.

The grinding process is to obtain the main purpose and effect of the present invention, but the coarse wood powder (1) is mixed in the finished subsidiary materials, but in the state of the final secondary molding it is difficult to obtain aesthetic synergistic effect by such coarse wood powder (1) When the surface is ground, a mixture of fine wood flour 2 and polyvinyl chloride 3 is filled between cross sections of adjacent coarse wood flour 1.

Such a shape is similar to that of marble, and it is inexpensive and simple to express a pattern that was difficult to express by a conventional method.

In addition, the design of the marble pattern with various colors can be freely expressed depending on which color series the manufacturer dyes, which greatly helps the aesthetics of the interior decoration.

On the other hand, in the embodiment the dyeing process of dyeing the coarse wood powder (1) to the desired color and the coarse wood powder (1), fine wood powder (2) and polyvinyl chloride (PVC) powder (3) pulverized into a fine powder In the mixing process, a pigment master batch having a maximum length of at least 2 mm or more is directly added in place of the process of dyeing coarse wood powder (1), and fine wood powder (2) and polyvinyl chloride (PVC) pulverized into fine powder ) Mixing the powder (3), but the fine powder (2) and the polyvinyl chloride powder (3) to maintain a ratio of at least 20% of the total weight, respectively, the polyvinyl chloride powder is heated and molten in a constant state It may be replaced by a mixing process of mixing to mix.

According to the present embodiment, after the first step of the primary molding process for molding the mixture mixed in the mixing process in a molten state, but in a predetermined size and shape in consideration of the ratio of compression and grinding in the subsequent process, and primary molding Compared to the above embodiment, the second molding process of compressing the molded article by compression press for a predetermined time and the grinding process of grinding at least 1 mm of one side of the formed subsidiary material are fine and contrast ratio is different. Excellent pattern of patterns is formed.

As described above, the present invention has a surface pattern similar to marble, but can be produced in various colors and combinations thereof, thereby improving the aesthetics of the subsidiary materials.

In addition, there is an effect of improving the durability of the interior interior materials by solving the problem of weakness and durability of the wood weakness and weakness and bending well to the heat of synthetic resin.

In addition, it is lighter than synthetic resin and has excellent durability and organizational orientation, making construction easier.

In addition, by reducing the toxic gas generated in the fire situation has the effect of reducing the secondary damage caused by the toxic gas in the fire.
