The present invention relates to a method for producing a finishing material of a floor covering the end of the floor to be constructed on the building floor to protect the finish.

Floor finishes, such as material separators, are used to wrap and protect the ends of floors constructed on slab floors in buildings, particularly apartments, or to separate dissimilar materials between floors and tiles.

As shown in FIG. 3, the floor finishing material 20 is installed at the interface between the floor 21 and the tile 22 or marble to divide and disperse the different materials so as to enhance the aesthetics of the floor 21 or the floor 21. The end of the marble 22 is wrapped and protected and aligned. As the floor finishing material 20 used, aluminum and brass or stainless metal and plastic materials are used.

However, in case of floor 21, there is a pattern according to the color and ring of wood (also some tiles with wood patterns), so it is not suitable with metal materials such as aluminum or stainless steel and brass with golden or gray color. It is pointed out that.

For this reason, when making and using flooring (hereinafter referred to as tiles and stone) finishes made of metal, wood patterns and colors are formed by powder coating on the surface of metal to preserve wood grain and wood color, and UV on them. The coating is applied to produce an atmosphere having the same color and pattern as the floor 21, so that the aesthetics can be improved without splashing.

However, the above method requires a powder coating, so the product is very expensive, and if the coating is peeled off, if the original color of the metal, for example, aluminum is used, the gray or white image of the aluminum is exposed to the outside, which is more ugly. This is often unstable to secure and maintain a stable appearance, due to the use of expensive metal material has also caused a problem of rising floor construction costs.

On the other hand, in view of this, plastic materials are often used as floor finishing materials. Plastic materials are inexpensive, easy to mass-produce, and light. Especially, pigments can be mixed with plastic raw materials to express a specific single color freely. While it has the advantage of being able to decorate the floor colorfully, it is difficult to express the unique pattern and color according to the rings of the floor itself. There was no.

For this reason, the floor finishing material is extruded into plastic and molded, and the surface of the floor is printed with a pattern and color printed veneer sheet, and UV coating is applied to prevent scratching and increase wear resistance. It is possible to provide a floor finishing material has been widely used as a floor finishing material of houses, including apartments.

However, the coating method of the patterned paper, such as the thin surface of the raw material is worn out as time passes, the surface of the raw material is exposed and tattered, causing the appearance of spoiled aesthetics, which is a big factor for the constant complaints of consumers. In addition to the increase in maintenance costs to the contractor, there was a problem that the replacement work is not easy because the floor must be removed to replace the new product.

Accordingly, the present invention has been proposed in view of the above-mentioned point, and its purpose is to be manufactured to have a pattern and color of floors that are light and inexpensive, and constructed, even if wear occurs or scratches over time. The present invention provides a method of manufacturing a floor finishing material that can improve interior aesthetics and reduce maintenance costs by maintaining colors.

In order to achieve the above object, the present invention is a PVC as a main material, the step of preparing a powdered first compounding material having a specific color;

      Preparing a second compounding material containing PVC as a main material and blending to have a different color and different melting point than the first compounding material;

      Inserting the second compound material into an extruder, extruding and cooling to form pellets having a granular shape by cutting to a size of 1.5 to 5 mm;

      Mixing the pellets with respect to the first compounding material in an amount of 6 to 15 wt%, and then inserting the pellets into an extruder to extrude while heating at 150 to 200 ° C .;

      Cooling the extrudate having passed through the die;

      Cutting the cooled extrudate to the required length;

Characterized in that consisting of.

In addition, according to a preferred embodiment of the present invention, the first compounding material is 85 to 88% by weight of PVC, stabilizer 2.0 to 3.3% by weight, processing aid 3.0 to 3.9% by weight, lubricant 1.5 to 2.0% by weight, pigment 0.6 to 1.0% by weight. And it is prepared by mixing the filler 4.0 to 4.9% by weight in powder form,

The second compounding material is PVC 89.5-91.5% by weight, stabilizer 2.5-2.9% by weight, processing aid 0.7-1.1% by weight, lubricant 0.3-0.7% by weight, pigment 0.7 ~ of a different color than the pigment color of the first compounding material 1.1 wt% and 4.0 to 5.0 wt% of a filler are prepared by mixing in a powder state.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing an embodiment of the floor finishing material manufactured according to the present invention, Figure 2 is a view illustrating a method for manufacturing a floor finishing material according to the present invention roughly T-shaped or a-shaped, c-shaped floor end of the present invention In order to manufacture the floor finishing material 100 having a shape that can cover the upper portion of the first to prepare a first composite material (1) made of PVC as the main raw material.

The first blended material (1) is 85 to 88% by weight of PVC, 2.0 to 3.3% by weight of stabilizer, 3.0 to 3.9% by weight of processing aid, 1.5 to 2.0% by weight of lubricant, 0.6 to 1.0% by weight of pigment and filler It is formed by mixing 4.0 to 4.9% by weight, all of which are combined in a powdery state like sugar.

In addition, a second blended material 2 is produced in which a property that sags like a gum when extruded due to a difference in melting point from the first blended material 1 is produced, and the second blended material 2 is replaced with the first blended material. The second blended material (2) is composed of PVC as the main material, 89.5-91.5% by weight PVC, stabilizer 2.5-2.9% by weight, processing aid 0.7-1.1% by weight, lubricant 0.3 0.7 wt% to 0.7 wt% of the pigment of different color from the pigment of the first blending material and 4.0 wt% to 5.0 wt% of the filler are mixed in a powdered state to mix evenly in the high speed mixer (3), At this time, since the grains are rubbed with each other during mixing, the temperature is increased by frictional heat, and then cooled to room temperature after mixing (4).

As the stabilizer, DLP (Dilead Pthalate) and Ca-St (Calcium Stearate) are used, and NBR rubber or acrylic is used as the processing aid (for example, the brand name CHEMIGUM product can be used as the processing aid). As the lubricant, stearic acid salt, polyethylene wax or stearic acid may be used. For example, the brand name Ac-629 or ST-A may be used as the lubricant.

In addition, the filler (Filler) is often used stone or hard coal (CaCO3), the pigment may be used, for example, R-902 to represent the unique color of each compound (1) (2).

The second compound material (2) is added by 6 to 15% by weight relative to the first compound material (1), the mixing ratio of the processing aid and lubricant components of each of the compounding materials (1) (2) is different The reason is that the melting temperature (melting point) of each compounding material (1) (2) is different according to the amount of processing aid and lubricant component. This is because the floor finishing material 100 in which the color naturally forms a laminar flow pattern can be obtained.

That is, when the first compound material (1) and the second compound material (2) are mixed in the extruder 10 as described later, the color is uniformly agitated due to the melting temperature difference and integrated into one color. In the state that maintains its own color, it continuously extends in the longitudinal direction like a snail, forming a wood pattern. At the same time, the processing aid lowers the processing temperature during PVC processing and excessive heat generated inside during extrusion. It has the effect of lowering the lubricant, and the lubricant serves to reduce friction between materials and the machine surface of the extruder.

However, in mixing the second compound material 2 with the first compound material 1 in a powder state, the powder is not mixed as a powder state but made into pellets, that is, a granule having a size of 1.5 to 5 mm, and thus the first compound material in a powder state. It is mixed in (1).

This is one of the important core of the present invention, the first compounding material (1) forms the base color of the flooring material 100 body, while the second compounding material (2) has a specific color, for example wood It is used to make a pattern that is different from the basic background color to form a pattern to form a pattern that is continuously stretched at irregular intervals to form a pattern. For this purpose, a grain shape of a suitable size that is easily scattered irregularly rather than powder that is easily mixed The reason why it is made of in pellet is that the pattern of the shape like wood grain is formed very naturally.

To this end, the second mixture material 2 is mixed with each component in the high speed mixer 3 (the temperature rises to about 100 ° C by friction), and then cooled (4) to room temperature through a cooler, and then extruder (5). Into a solid body while continuously pushing with a rod member with a diameter of 1.5 to 5 mm, cooled in a cooler (6), and cut into lengths of 1.5 to 5 mm (7) to finally produce a pellet having a size of 1.5 to 5 mm. (8), the pellet (8) is mixed by about 10% by weight in a weight ratio to the first compounding material (1) and then used as an extrusion material for the production of floor finishing material.

The mixed mixture 9 is injected into the hopper of the extruder 10 and extruded. The extruder is equipped with a temperature controller 11 having a heating wire is extruded while heating the extrudate to 150 ~ 200 ℃ during extrusion.

At this time, the melting point and particle size of the two components (1) (2) of the extrudate are different, so that each material is in a muggy state (not completely melted and agitated, rather than pellets to keep their position). As the gum or toe is stretched in the longitudinal direction, the two colors match and a natural pattern such as wood veneer is formed.

This is like a candy made of various colors to form a certain shape. If you mix the dough with different colors and stretch it together, the unique color is kept intact. It applies the same reason that the shapes appear to be the same.

In this way, the extrudate 13, which has passed through the mold 12 at the end of the extruder 10, has a specific shape, for example, as shown in FIG. 1, and then is cooled by passing through a cooling bath 14 and then towed. By cutting the cutter 15 at the rear of the roller is to obtain a floor finishing material 100 of the desired length.

And the surface of the floor finishing material 100 can be given a luster by wax coating or UV coating, if necessary.

(Example)

1st compound: PVC 100kg, stabilizer 3kg, processing aid 4kg, lubricant 2kg, pigment ivory 1kg, filler 5kg (all powder)

2nd compound material: PVC 100kg, stabilizer 3kg, processing aid 1kg, lubricant 0.5kg, pigment pink 1kg, filler 5kg (all powder)

The first compounding material 1 was evenly mixed in the mixer 16, the second compounding material 2 was added to the high speed mixer 3, the materials were combined, and cooled to 25 ° C. In addition, the second mixture material 2 cooled to room temperature was introduced into the extruder 5, taken out in the form of a round bar having a diameter of 3 mm, and cut at 3 mm intervals to produce pellets having a size of 3 mm.

12 kg of the 3 mm pellets were mixed with the 115 kg of the first blending material (the mixing does not need to be uniform, so that they may be properly mixed or the pellets may be mixed in various places) and extruded into an extruder. . The extrudate obtained through the mold was passed through a 20 ° C. cooling water bath and allowed to stand at room temperature, and then cut to a length of 4 m to obtain a floor finishing material.

The color and pattern of the obtained floor finishing material 100 is as shown in Figure 1, the dark pink lines than the ivory color of the ground color is naturally continuous in the form of a strip, you can feel the familiarity like the wood pattern, the pattern and color formed only on the surface Rather, it was formed to the inside of the body, so that the same pattern and color could be maintained even if the surface was scraped, and the scratches were not noticeable.

As described above, the present invention mixes and extrudes two types of compounding materials that differ in the blending ratio of the compounding materials and the color of the pigment so that the melting point is different from each other when extruded PVC, and the one side of the compounding material as a pellet By mixing with the other compounding material in the form of powder to be extruded to a specific shape, the stripes of different colors appear naturally spreading on the base ground color, so that the wooden pattern can be expressed, and the floor finish material is worn or scratched. Even though it keeps the manufactured pattern and color and the scratch part is not greatly revealed by the stripes, unlike the conventional one, continuous after-sales work is not required due to the surface damage of the floor finishing material. There is an effect to provide a floor finish as a building material.
