BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for producing synthetic wood having a non-slip phosphorescent edge,

More particularly, the present invention relates to a method of manufacturing synthetic wood with non-slip phosphorescent corners, and more particularly, to a method of manufacturing a synthetic wood having non-slip phosphorescent edges by forming non-slip phosphorescence edges at edges of synthetic wood, The present invention relates to a method of manufacturing a synthetic wood having a non-slip luminous edge formed thereon so as to reduce the risk of slipping when climbing the stairs because it does not slip even in the presence of moisture.

Generally, it is necessary to construct a walkway for walking on the trails or trails. Materials used for these gravel roads have been stone, wood, concrete, brick, etc. Recently, synthetic wood has been widely used.

Synthetic timber is not easily rotten and durable, so it has been installed in many trails and trails recently. In recent years, many people often take a walk or exercise at night, and when climbing up and down a stairway in a hiking trail or a promenade, it can cause problems such as an accident due to a bad foot.

In order to solve these problems, many proposals have been made to prevent the risk by forming the phosphorescent material on the bottom in a large number of applications.

Patent No. 10-0917375 relates to a method for producing a synthetic wood having a phosphorescent display part, which comprises 50 to 60 parts by weight of wood powder, 30 to 50 parts by weight of an olefin resin, 1 to 5 parts by weight of a binder, Mixing 2 to 5 parts by weight of the first material 110 to prepare a first material 110; Melting the first material (110) and preparing it for extrusion in a first extruder (100), melting the phosphorescent master bit set (210) and preparing it for extrusion in a second extruder (200); Extruding molten first master material 110 passing through mold 50 while passing molten phosphorescent master bit 210 through mold 50; And a step in which the first material (100) forms a synthetic wood (300) and the phosphorescent master label (210) is cooled while forming a phosphorescent display part. I am suggesting.

Japanese Patent No. 10-1079306 discloses an artificial wood for non-slip and a method of manufacturing the same. The anti-slip artificial wood is formed by forming and installing a plate mounting groove in a slip prevention projection, and a slip prevention plate . Wherein the slip prevention plate comprises 10 to 35 wt% of a phosphorescent pigment, 2 to 15 wt% of a phosphite, 0.5 to 5 wt% of a casein salt, 0.5 to 5 wt% of a heat sensitizer, 1 to 5 wt% And a method for manufacturing the artificial wood for non-skid prevention.

In addition, Japanese Patent No. 10-1079307 is similar to Japanese Patent No. 10-1079306, which discloses an artificial wood composition for non-slip, a method for manufacturing the same, and a technique for the product. Specifically, a slip prevention plate made of a rubber material is provided at a position corresponding to a slip prevention projection provided to prevent sliding on the surface of artificial wood, thereby preventing a safety accident, The product.

The above techniques are good in that the phosphorescent portion is formed on the bottom surface and the slip prevention function is formed in the phosphorescent portion. However, when a person climbs the staircase, most people climb the staircase using the stair edge. There is a problem that an accident that slips and falls may occur, leading to a catastrophic accident, particularly to a child or an elderly person.

Further, since the luminous flux is formed on the plane which is the bottom surface, there is a problem that it is not well recognized at night.

In addition, since the luminous part is formed on the bottom surface, there was almost no visual and advertisement effect through the people walking on the trails or hiking trails.

The present invention has been devised to solve the above-mentioned problems, and it is an object of the present invention to provide an apparatus and a method for forming a corrugated edge of a staircase, which not only serves as a guide when climbing a staircase to people moving along a mountain trail or a promenade at night, The present invention also provides a method of manufacturing a synthetic wood having a non-slip luminous edge which prevents accidents such as slipping up and down stairs even when moisture is present.

(A) 25 to 30% by weight of a polyolefin-based resin, 60 to 70% by weight of a woodywood or rice hull of a softwood, 0.003 to 0.02% by weight of a coupling agent composed of a fatty acid- A synthetic wood component composed of 0.5 to 2% by weight of a dispersing wax, 0.1 to 2% by weight of a moisture inhibitor, 0.5 to 10% by weight of a pigment and 0.5 to 2% by weight of a fatty acid-based wood wax is molded and extruded in a first molding die step; (b) The extruded synthetic wood is mixed with 60 to 80% by weight of polypropylene resin, 4 to 7% by weight of polyethylene wax, 1 to 4% by weight of calcium stearic acid, 15 to 25% by weight of long- Molding the phosphorescent edge in a second molding die to which a phosphorescent component of weight% is administered; (c) cooling the synthetic wood having the phosphorescent edge formed therein; (d) cutting the cooled synthetic wood to a predetermined size. The method of manufacturing a synthetic wood having a non-slip luminous edge formed thereon.

The first molding die of the present invention is characterized in that a '-shaped' protrusion is formed at one corner. Shaped projecting portion is formed, so that a tongue-shaped groove is formed at one side edge of the synthetic wood to be extruded.

In the present invention, the second forming die has a rectangular cross section, and the corresponding portion of the first forming die, in which the protruding portions are formed, is provided with irregularities or ridges. And a phosphorescent component is inserted into the tongue-shaped groove so that the tongue-shaped groove can be integrally extruded together. The phosphorescent edge to be extruded functions as a non-slip function so that the groove portion does not slip when the person touches the edge of the tread.

In the present invention, one or more bands into which phosphorescence components are injected for identification may be formed on the horizontal plane or the vertical plane of the synthetic wood together with the phosphorescence edge. By extending the band horizontally or horizontally on the horizontal plane or the vertical plane, it is possible to have an effect of attracting attention to the walkers using the stairs.

Between the step (b) and the step (c) in the present invention, it is possible to further include the step of forming a stripe on the luminous edge. The step of forming the pattern further includes a third forming mold for forming a pattern on the edge of the phosphorescent light. The third forming frame is constituted by a rotating roller, and a pattern is formed on the outer circumferential surface of the roller, so that the synthetic wood is in thermal contact with the roller to form a pattern. And inserts a pattern on the front surface of the extruded synthetic wood to display an advertisement or a manufacturer. If you run an ad, you can use it as a separate source of income. In addition, the pattern can be formed by thermally fusing a paint having no phosphorescent component, or by thermally fusing luminous components of different colors.

In the present invention, 1 to 3% by weight of glass powder is further added to the luminous component. By adding glass powder to the luminous component, it is possible to induce irregular reflection of light so that it can easily come into view of people.

The present invention has an advantage in that it can act as a guide for the location of people by emitting light when moving on stairs such as a mountain trail or a promenade.

Further, the present invention has the effect of preventing the accident from occurring by not forming a non-slip luminous part at the corner, even when moisture is present.

In addition, since the pattern can be inscribed on the front surface of the synthetic wood, the present invention has an advantage in that it is possible to write an advertisement or a manufacturer.

FIG.

1 is a perspective view of a synthetic wood with a luminous edge formed according to the present invention. As shown in the figure, the synthetic wood 10 formed with the phosphorescent edge is composed of the synthetic wood 100 and the phosphorescent edge 110 formed at the edge of the synthetic wood. As shown in the drawing, the phosphorescent edge 110 is formed with irregularities or ridges 111 to perform a non-slip function.

Hereinafter, a method of manufacturing a synthetic wood having a phosphorescent edge will be described in detail. (A) 25 to 30% by weight of a polyolefin resin, 60 to 70% by weight of a woodywood or rice hull of a softwood, a coupling agent 0.003 to 0.02 of a fatty acid-based maleic anhydride, A synthetic wood component composed of 0.5 to 2% by weight of wood wax, 0.1 to 2% by weight of moisture inhibitor, 0.5 to 10% by weight of pigment and 0.5 to 2% by weight of fatty acid-based wood wax, Molding; (b) The extruded synthetic wood is mixed with 60 to 80% by weight of a polypropylene resin, 4 to 7% by weight of a polyethylene wax, 1 to 4% by weight of calcium stearic acid, 15 to 25% % Of the phosphorescent component is administered; (c) cooling the synthetic wood on which the pattern is formed; (O) cutting the cooled synthetic wood to a predetermined size.

As shown in FIG. 2, in step (a), components of synthetic wood are mixed, heated and melted, and molded and extruded through a first molding die. The synthetic wood is composed of 25 to 30% by weight of a polyolefin resin, 60 to 70% by weight of woodywood or rice husks, 0.003 to 0.02% by weight of a ketalizing agent consisting of fatty acid anhydride maleic acid, 0.5 to 2% 0.1 to 2% by weight of an inhibitor, 0.5 to 10% by weight of a pigment, and 0.5 to 2% by weight of a fatty acid-based wood wax are mixed, and the mixed synthetic wood components are melted by heating and extruded through a mold. The first forming die 20 has a protruding portion 21 formed at one side thereof. The portion is for forming a space in which the phosphorescence edge can be formed in the next step. In addition, as shown in FIG. 2, a ridge can be formed to prevent water such as rain from being accumulated on the upper part of the synthetic wood and to allow moisture to escape through the inner ridge.

After passing through the first shaping mold, step (b) is performed as shown in FIG. In step (b), the phosphorescent component is injected into the edge portion of the synthetic wood extruded through the first molding die 20 to perform molding extrusion. The phosphorescent component is composed of 60 to 80% by weight of polypropylene resin, 4 to 7% by weight of polyethylene wax, 1 to 4% by weight of calcium stearic acid, 15 to 25% by weight of long wavelength light and 1 to 2% by weight of liquid paraffin. The phosphorescent component is heated and melted, and the mixture is extruded together with the synthetic wood while being introduced into a second molding mold. The polypropylene resin used as a phosphorescent component preferably has an MI (Melting Index) value of about 10 to 15. The polyethylene wax acts as a lubricant and dispersant. Generally, a low-molecular polyethylene wax is used, and the melting temperature of the low-molecular polyethylene is about 100 ° C. Calcium stearic acid is used as an external activator, so that calcium stearic acid can easily fall into a metal mold. The long-phosphorescent pigment acts as a phosphorescent component for emitting light at night. Liquid paraffin acts as a binder in mixing. Liquid paraffin is injected to mix and melt the phosphorescent component, and the phosphorescent component is injected through the charging port 32 of the second molding die 30. The luminous component is injected into the space defined by the projecting portions of the first forming mold 20 and the concave and convex portions 31 are formed on the inner circumferential surface of the second forming mold. The phosphorescent edge 110 of the synthetic wood is extruded through the unevenness and ridges 31 to form irregularities or ridges 111 on the surface of the phosphorescent edge to perform the non-slip function.

As shown in Figs. 4 and 5, the phosphorescent component identifying strips 34 and 34 'can be further formed on the flat surface or the entire surface of the side on which the phosphorescent edge is formed, while forming the phosphorescence edge. By further forming the identification band 34, 34 'of the phosphorescent component, the pedestrian can easily recognize that there is a step or the like, so that the safety of the pedestrian can be achieved. Inlets 33 and 33 'are formed which flow into the identification strips 34 and 34' to form the identification strips 34 and 34 '.

Next, in step (c), the finished synthetic wood is cooled, and it may further include (e) forming a pattern before cooling. As shown in FIG. 6, the pattern is formed in the state where the phosphorescent edge is formed. In the step of forming the pattern, a third forming mold 40 is used. The third molding die 40 forms a pattern while passing the flat portion of the luminous edge 110 through the rotating roller 41. A pattern 42 is formed on the outer circumferential surface of the roller 41 and a rotary shaft 43 is provided for rotating the roller 41. The roller 41 rotates while being heated to a predetermined temperature and forms a pattern on the phosphorescent edge 110 after applying the phosphorescence component of another color to the surface of the pattern 42. Alternatively, A pattern can be formed on the phosphorescent edge 110 by using the pattern. Further, a glass powder may be further added to the luminous component to cause diffuse reflection of light. Therefore, when a flashlight or the like is shined, it is illuminated by irregular reflection caused by the glass powder, so that the pedestrian can easily recognize that the stairway is a step. The added glass powder may be added in an amount of 1 to 3% by weight.

When the formation of the pattern 112 is completed, step (d) is performed next. The composite wood 10 on which the phosphorescent edge is formed is cooled. The cooling step can be cooled using cooling water.

When the cooling is completed, the synthetic wood 10 is cut at regular intervals and ready for shipment. FIG. 7 shows synthetic wood formed at regular intervals using the finished synthetic wood 10.

FIG. 8 shows a state where a step is formed by using synthetic wood having a luminous edge formed according to the present invention. By forming the non-slip portion at the corner portion as shown in the figure, pedestrians can walk safely without slipping even when moisture is present.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It is to be understood that the techniques which can be used by those skilled in the art are included in the technical scope of the present invention.
