Description

단판적층재를 사용한 조경재의 제조방법{Manufacturing method of landscape material using veneer laminate}Manufacturing method of landscape material using veneer laminate}

본 발명은 단판적층재를 사용한 조경재에 관한 것으로, 보다 상세하게는, 데크, 기둥 또는 레일에 원목이나 합성목재를 사용하지 않고 다양한 규격과 형상 및 색상으로 제작할 수 있는 단판(veneer)을 적층시킨 단판적층재(LVL)를 사용한 조경재 및 그 제조방법에 관한 것이다.The present invention relates to a landscaping material using a veneer laminate, and more particularly, a veneer laminated with veneers that can be manufactured in various sizes, shapes and colors without using solid wood or synthetic wood for decks, columns or rails. It relates to a landscaping material using a laminate (LVL) and a method of manufacturing the same.

야외 여가생활 시간이 증가함에 따라 야외에 설치하는 데크, 기둥 또는 레일 등과 같은 조경재로 나무가 사용되면서 천연목재의 수요가 꾸준히 증가하고 있는데, 천연목재를 직접 이용할 경우 자연미가 부각되는 장점은 있으나, 재료가 무겁고 규격 및 형상이 한정되어 있어서 시공이 불편할 뿐만 아니라 천연목재 자체가 고가이며, 특히 원목 생산량에는 한계가 있고 대량생산이 어렵다는 문제가 있다. 또한, 천연목재는 강도와 내부후성(耐腐朽性), 내구성, 내열성, 내충격성, 항균성 및 방충효과 등의 물성이 부족하다는 문제가 있으며, 주기적으로 니스나 락카칠을 해줘야 하므로 관리가 불편하다는 문제가 있다.As the outdoor leisure time increases, the demand for natural wood is steadily increasing as wood is used as a landscaping material such as decks, pillars or rails to be installed outdoors.If natural wood is used directly, the natural beauty is highlighted, but the material It is not only inconvenient to construct because it is heavy and has limited specifications and shapes, and natural wood itself is expensive. In particular, there is a problem that there is a limit to the production amount of raw wood and mass production is difficult. In addition, natural wood has a problem of lack of physical properties such as strength, weather resistance, durability, heat resistance, impact resistance, antibacterial property and insect repellency, and it is a problem that management is inconvenient because it must be regularly varnished or lacquered. There is.

이러한 문제를 해결하기 위해 천연목재와 유사한 질감 및 외관을 나타내는 합성목재가 널리 사용되고 있는데, 합성목재는 나무 성분과 플라스틱 성분 및 각종 첨가제를 혼합해서 압출방식으로 제조한 것으로, 나무 성분으로는 목재 부스러기, 톱밥 등과 같은 목분(木粉)이 사용되며, 플라스틱 성분으로는 열가소성수지가 사용되고, 용도와 기능에 따라 다양한 종류의 첨가제를 사용하고 있다. 이러한 합성목재는 천연목재나 방부목에 비해 물(습기)에 강하고 변색이나 뒤틀림이 없어 유지 관리가 편리하여 등산로, 산책로, 호수 주변 등에 디자인형 울타리의 기둥, 레일, 펜스, 루버 등에 많이 사용되고 있으나, 온도에 따라 수축과 팽창이 많고 충격강도에 약해서 파손이 잘 된다는 단점이 있으며, 내구성에 있어서는 천연목재에 비해 현저히 떨어지는 문제점을 갖고 있다.To solve this problem, synthetic wood having a texture and appearance similar to that of natural wood is widely used. Synthetic wood is manufactured by extrusion method by mixing wood components, plastic components, and various additives, and wood components include wood chips, Wood powder such as sawdust is used, thermoplastic resin is used as a plastic component, and various kinds of additives are used depending on the use and function. Synthetic wood is more resistant to water (moisture) than natural wood or preservative wood, and has no discoloration or distortion, so it is convenient to maintain. It is widely used for design-type fence posts, rails, fences, louvers on hiking trails, trails, and lakes. As a result, there is a drawback in that it has a lot of contraction and expansion, and it is weak in impact strength, so that it is easily damaged, and in terms of durability, it has a problem that is significantly lower than that of natural wood.

합성목재를 데크, 기둥 또는 레일 등과 같은 조경재에 적용한 기술을 예로 들면, 특허등록 제668493호 "조인트를 구비한 합성목제 휀스"는 연질의 고무 및 플라스틱류로 가공된 조인트를 합성목재로 제작된 레일과 레일 사이에 배치하여 기온 차이에 의한 합성목재의 수축과 팽창을 흡수해 주도록 한 기술이다. 하지만, 대부분의 조경재가 옥외에 설치되기 때문에 외기온도의 변화 등과 같은 자연적인 요인에 의해 수축과 팽창 및 외적인 충격 등에 의해 합성목재가 파손되는 문제가 빈번하게 발생하고, 합성목재를 압출방식으로 제조하기 때문에 합성목재 자체를 임의의 크기와 두께로 제조하는 데에는 문제가 있다.For example, the technology of applying synthetic wood to landscape materials such as decks, columns, rails, etc., Patent Registration No. 6668493 "Synthetic wooden fence with joints" is a rail made of synthetic wood with joints processed with soft rubber and plastics. It is a technology that is placed between the rail and the rail to absorb the contraction and expansion of synthetic wood caused by temperature differences. However, since most landscaping materials are installed outdoors, there are frequent problems that the synthetic wood is damaged due to contraction, expansion and external impact due to natural factors such as changes in outside temperature, and the synthetic wood is manufactured by extrusion method. Therefore, there is a problem in manufacturing the synthetic wood itself to an arbitrary size and thickness.

한편, 최근에는 합성목재의 단점을 보완하기 위하여 합성목재 내부에 형성된 공간에 철재를 삽입한 합성목재 조경재가 출현했으나, 철재와 합성목재의 기온에 따른 팽창율이 다르고, 철재가 외기온도 변화에 따라 팽창되거나 수축되는 정도가 합성목재보다 심하기 때문에 하절기와 동절기에는 철재의 과도한 팽창 및 수축으로 인하여 철재와 합성목재가 분리되거나 조립이 헐거워지면서 철재가 흔들거리게 되어 합성목재 조경재의 강도가 저하되는 문제가 있다.On the other hand, recently, in order to compensate for the shortcomings of synthetic wood, synthetic wood landscaping materials in which iron materials are inserted into the space formed inside the synthetic wood have appeared, but the expansion rate of steel and synthetic wood varies according to the temperature, and the steel material expands according to the change of outside temperature. Since the degree of contraction or shrinkage is more severe than that of synthetic wood, there is a problem in that the strength of the synthetic wood landscape material decreases in the summer and winter seasons due to the excessive expansion and contraction of the steel material, which causes the steel material and the synthetic wood to separate or assemble loose and the steel material shakes.

본 발명은 상기와 같은 문제를 해결하기 위하여 안출된 것으로, 본 발명의 목적은, 데크, 기둥 또는 레일과 같은 조경재에 원목이나 합성목재를 사용하지 않고 단판(單板, veneer)을 적층시킨 단판적층재(Laminated Veneer Lumber; LVL)를 사용함으로써 다양한 규격과 형상 및 색상은 물론 저렴하면서도 휨이나 뒤틀림과 같은 변형이 없고 강도와 내부후성(耐腐朽性) 등을 향상시킬 수 있는 단판적층재를 사용한 조경재 및 그 제조방법을 제공하기 위한 것이다.The present invention has been conceived to solve the above problems, and an object of the present invention is a single plate laminated laminated veneer without the use of solid wood or synthetic wood on landscape materials such as decks, columns or rails Laminated Veneer Lumber (LVL) is used to improve the strength and weather resistance without deformation such as warping or warping while being inexpensive as well as various sizes, shapes and colors.

Forming a thick laminate; Manufacturing a first veneer laminate by applying heat and pressure at the top and bottom of the laminate stacked to a predetermined thickness for a predetermined time; Cutting the manufactured single-plate laminate according to the standard; It characterized in that it is manufactured through the step of coating oil stain on the surface of the cut veneer laminate.

바람직하게는, 제1 단판적층재가 제작된 후에, 제1 단판적층재 상부에 접착제를 도포한 다음, 하부에 위치한 제1 단판적층재의 목리방향과 평행하게 제1 단판적층재를 적층시키는 공정을 반복하여, 일정 두께로 적층된 제1 단판적층재의 상부에 일정 시간동안 압력을 가하여 제2 단판적층재를 제작하는 단계를 더 거쳐서 더 두꺼운 단판적층재를 제조한다.Preferably, after the first veneer laminate is manufactured, an adhesive is applied to the top of the first veneer laminate, and then the process of laminating the first veneer laminate in parallel with the direction of the neck of the first veneer laminate located below is repeated. Thus, the step of producing a second veneer laminate by applying pressure to the top of the first veneer laminate laminated to a certain thickness for a certain period of time is further performed to manufacture a thicker veneer laminate.

바람직하게는, 적층재를 형성하는 단계에서 도포하는 열경화성수지는 요소-멜라민 수지이다.Preferably, the thermosetting resin applied in the step of forming the laminate is a urea-melamine resin.

지금까지 데크, 기둥 또는 레일 등과 같은 조경재를 설치함에 있어서 원목 또는 합성목재를 많이 사용하였는데, 본 발명에 따른 조경재는 원목이나 합성목재를 사용하지 않고 단판(veneer)을 적층시켜 접착제로 접착시킨 단판적층재(LVL)를 사용하기 때문에 조경재가 필요로 하는 다양한 규격과 형상 및 색상으로 제작할 수 있고, 휨과 뒤틀림과 같은 변형이 없으며, 특히 소비자가 요구하는 데크의 두께와 색상 및 기능성을 맞출 수 있어서 소비자의 다양한 요구에 부응하는 맞춤 제작이 가능하며, 원목이나 합성목재에 비해 가격면에서 훨씬 저렴하면서도 원목을 사용하지 않으므로 산림훼손을 줄일 수 있어서 환경친화적이다.Until now, in installing landscaping materials such as decks, columns, rails, etc., solid wood or synthetic wood has been widely used, but the landscaping material according to the present invention does not use solid wood or synthetic wood, but veneers are laminated and bonded with an adhesive. Because of the use of LVL, it can be manufactured in various sizes, shapes and colors required by landscape materials, and there is no deformation such as warping or warping, and in particular, it is possible to match the thickness, color and functionality of the deck required by consumers. It can be customized to meet the various needs of the company, and it is much cheaper in terms of price compared to solid wood or synthetic wood, but it is eco-friendly because it can reduce forest damage because it does not use solid wood.

또한, 단판적층재의 제조 공정도 간편하고, 단판적층재를 우레탄 접착제를 사용하여 접착시킨 것이기 때문에 강도와 내부후성(耐腐朽性), 내구성, 내충격성, 내수성, 내열성 및 방충효과 등이 현저하게 향상되며, 야외에서 눈과 비를 맞는 곳에 설치하더라도 단판적층재가 박리되거나 변형되지 않을 뿐만 아니라 조경재 설치후 조경재의 변형, 파손, 썩음 등으로 인해 주기적으로 조경재 교체공사를 할 필요가 없어서 자원 낭비도 줄이고 예산도 절감할 수 있다.In addition, the manufacturing process of the veneer laminate is also simple, and since the veneer laminate is bonded with a urethane adhesive, the strength, weather resistance, durability, impact resistance, water resistance, heat resistance, and insect repellency are significantly improved. Even if it is installed outdoors where it is exposed to snow and rain, the veneer laminate is not peeled or deformed, and there is no need to periodically replace the landscape material due to deformation, damage, and rot of the landscape material after installation. You can also save.

본 발명에 따른 조경재의 가장 큰 기술적 특징은, 우레탄 접착제로 접착하여 적층시킨 단판적층재를 조경재에 사용함으로써 다양한 규격과 형상 및 색상으로 제작이 가능하고, 휨이나 뒤틀림과 같은 변형이 발생하지 않는 조경재를 제공할 수 있음은 물론 가격면에서 훨씬 저렴하면서도 강도와 내부후성(耐腐朽性) 등의 물성이 현저하게 향상된 조경재를 제공할 수 있게 했다는 점이다.The greatest technical feature of the landscape material according to the present invention is that it is possible to manufacture in a variety of standards, shapes and colors by using a single-plate laminate laminated by bonding with a urethane adhesive for the landscape material, and does not cause deformation such as warping or warping. It is possible to provide a landscaping material with remarkably improved physical properties such as strength and weather resistance while being much cheaper in terms of price.

본 명세서에서 '레일'이란 디자인형 울타리에서 일정간격을 두고 수직상태로 고정 설치된 기둥과 기둥 사이를 연결하여 울타리 역할을 하는 난간 또는 난간대를 지칭하는 용어로 사용하고, '조경재'란 데크, 디자인형 울타리에서 기둥 또는 레일 등과 같은 용도로 사용하는 자재를 총칭하는 용어로 사용한다는 점을 밝혀둔다.In this specification, the term'rail' is used as a term referring to a railing or railing that acts as a fence by connecting the pillars and columns fixedly installed in a vertical state at regular intervals in a design type fence, and'landscape material' is a deck, design type It should be noted that the material used for purposes such as poles or rails in fences is used as a generic term.

단판적층재(Laminated Veneer Lumber; LVL)는 단판(單板, veneer)을 목리(木理)방향(섬유방향)으로 평행하게 수 겹에서 수십 겹을 겹치고, 단판과 단판 사이를 접착제로 접착시킨 후 열과 압력을 가해서 만든 것으로, 치수안정성이 좋고 높은 강도를 가지며 재료 간의 변이성이 적어서 힘을 받는 부위에 사용할 수 있는 장점이 있다. 반면, 합판의 경우에는 단판의 섬유방향이 직교하도록 적층시켜서 접착시킨 것이기 때문에 힘을 받는 부위에는 사용하는데 문제가 있다.Laminated Veneer Lumber (LVL) stacks several to tens of layers parallel to the veneer in the direction of the wood (fiber direction), and after bonding the veneer to the veneer with an adhesive, It is made by applying pressure, has good dimensional stability, has high strength, and has little variability between materials, so it can be used in areas subject to force. On the other hand, in the case of plywood, since it is laminated and bonded so that the fiber directions of the veneer are orthogonal, there is a problem in using it in the area receiving force.

본 발명에 따른 단판적층재를 사용하여 조경재를 제조하는 방법은, 베니어 상부에 열경화성수지를 도포한 다음, 하부에 위치한 베니어의 목리(木理)방향과 평행하게 베니어를 적층시키는 공정을 반복하여 일정 두께의 적층재를 형성하는 단계(S1), 일정 두께로 적층된 적층재의 상부와 하부에서 일정 시간동안 열과 압력을 가하여 제1 단판적층재를 제작하는 단계(S2), 제작된 단판적층재를 규격에 맞게 재단하는 단계(S4), 재단된 단판적층재의 표면에 오일스테인을 도장하는 단계(S6)를 기본적인 공정으로 거치게 된다.The method of manufacturing a landscape material using the veneer laminate according to the present invention is to repeat the process of laminating the veneer in parallel with the direction of the veneer located below after applying a thermosetting resin on the top of the veneer. Forming a laminated material having a thickness (S1), applying heat and pressure at the top and bottom of the laminated material to a certain thickness for a certain period of time (S2), and standardizing the produced single-plate laminated material A step of cutting according to (S4) and a step (S6) of painting oil stain on the surface of the cut veneer laminate are performed as basic processes.

일반적으로 단판(單板)인 파인 베니어(fine veneer)는 두께가 2.2㎜인데, 이러한 파인 베니어를 목리방향이 평행하도록 적층시켜서 일정 크기(보통 규격은 1,220㎜×2,440㎜ 정도이다)의 적층재를 형성한다. 적층재 형성 단계인 S1 단계에서는 단판(11) 상부에 열경화성수지 접착제(12)를 도포한 다음, 하부에 위치한 단판의 목리방향과 평행하게 단판을 적층시키는 공정을 반복하여 필요로 하는 일정 두께의 적층재를 형성하게 된다. 통상적으로 11장을 적층시켜서 두께 24.2㎜인 1차 단판적층재(10)를 제작하게 되며, 물론 적층되는 단판(veneer)의 겹쳐지는 개수는 변경할 수 있다. S1 단계에서 단판(11) 상부에 도포하는 접착제(12)는 열경화성수지를 사용하는 것이 바람직하고, 본 발명에서는 요소-멜라민 수지를 사용하였다. 요소-멜라민 수지는 내수성, 내열성, 내약품성이 강하고 수축 팽창이 적으며, 특히 페놀수지에서는 불가능한 착색을 할 수 있는 장점이 있으며, 요소 수지나 멜라민 수지를 단독으로 사용할 때보다 요소-멜라민 수지를 사용할 경우에는 내수성과 접착력이 현저하게 개선된다. 또한, 목리방향이 평행하기 때문에 단판을 접착시킨 후 박리현상이 최소화 되게 된다.In general, fine veneers, which are veneers, have a thickness of 2.2 mm, and these fine veneers are laminated so that the direction of the neck is parallel to produce a laminate of a certain size (normal standard is about 1,220 mm × 2,440 mm). To form. In step S1, which is the step of forming a laminate, the step of applying a thermosetting resin adhesive 12 on the top of the veneer 11, and then laminating the veneer in parallel with the neck direction of the veneer located at the bottom, is repeated to laminate the required thickness. Will form ashes. Typically, 11 sheets are stacked to produce the primary veneer laminate 10 having a thickness of 24.2 mm, and of course, the number of overlapping veneers to be laminated can be changed. It is preferable to use a thermosetting resin as the adhesive 12 applied to the top of the veneer 11 in step S1, and in the present invention, a urea-melamine resin was used. Urea-melamine resin has strong water resistance, heat resistance, chemical resistance, and low shrinkage and expansion, and has the advantage of being able to color, which is not possible with phenolic resins, and urea-melamine resin is used rather than when urea resin or melamine resin is used alone. In this case, water resistance and adhesion are remarkably improved. In addition, since the neck direction is parallel, the peeling phenomenon after adhering the veneer is minimized.

제1 단판적층재(10)를 제작하는 단계인 S2 단계에서는 일정 두께로 적층된 적층재의 상부와 하부에서 일정 시간동안 열과 압력을 가하여 1차 단판적층재를 제작하는데(도 2 참조), 제1 단판적층재(10)는 단판(11) 사이에 열경화성수지를 도포하기 때문에 열과 압력을 가해서 접착시켜야 하며, S2 단계에서 적층재에 가하는 열은 90∼120℃이고, 10∼14㎏/㎠의 압력을 30∼60분 동안 가하게 된다. 만일 90℃ 보다 낮은 온도와 10㎏/㎠ 보다 낮은 압력을 가하게 되면 단판(11) 사이의 접착력이 약해서 제1 단판적층재(10)의 두께가 두껍게 만들어질 뿐만 아니라 단판 사이에 박리현상이 발생할 수 있다는 문제가 있고, 온도가 120℃ 보다 높으면 단판이 탄화될 수 있으며, 압력이 14㎏/㎠ 보다 높아도 너무 강하게 눌러지기 때문에 단판의 원형이 변형될 수 있다는 문제가 있다.In step S2, which is the step of manufacturing the first veneer laminate 10, the first veneer laminate is manufactured by applying heat and pressure for a certain period of time at the top and bottom of the laminate laminated to a certain thickness (see Fig. 2). Since the veneer laminate 10 is coated with a thermosetting resin between the veneers 11, it must be bonded by applying heat and pressure, and the heat applied to the laminate in step S2 is 90 to 120℃, and a pressure of 10 to 14 kg/㎠ Is applied for 30 to 60 minutes. If a temperature lower than 90°C and a pressure lower than 10 kg/㎠ are applied, the adhesive strength between the veneers 11 is weak and the thickness of the first veneer laminate 10 is made thick and peeling may occur between the veneers. There is a problem that there is a problem that, if the temperature is higher than 120°C, the veneer may be carbonized, and even if the pressure is higher than 14 kg/cm 2, the original shape of the veneer may be deformed because it is pressed too strongly.

제1 단판적층재(10)(통상적으로 두께가 24.2㎜ 정도이다)가 제작된 후에 제1 단판적층재(10)를 필요로 하는 규격에 맞춰 재단하여 사용할 수도 있으나, 더 두꺼운 단판적층재로 만들고자 할 때는 복수의 제1 단판적층재(10)를 접착제로 접착하여 적층시켜서 제2 단판적층재(20)를 제조하고, 제2 단판적층재(20)를 필요로 하는 규격에 맞춰 재단하여 사용한다.After the first veneer laminate 10 (usually about 24.2 mm thick) is manufactured, the first veneer laminate 10 may be cut and used according to the required standard, but to make it a thicker veneer laminate. In this case, a plurality of first veneer laminates 10 are bonded and laminated with an adhesive to prepare a second veneer laminate 20, and the second veneer laminate 20 is cut and used according to the required standard. .

제2 단판적층재(20)를 제작하는 S3 단계에서는, 제1 단판적층재(10) 상부에 접착제를 도포한 다음, 하부에 위치한 제1 단판적층재(10)의 목리방향과 평행하게 제1 단판적층재(10)를 적층시키는 공정을 반복하여, 필요로 하는 두께로 적층된 제1 단판적층재의 상부와 하부에서 일정 시간동안 압력을 가하여 제2 단판적층재(20)를 제작하게 된다(도 3a 참조). S3 단계에서 제1 단판적층재(10)와 제1 단판적층재 사이에 도포하는 접착제(22)는 우레탄 접착제를 사용하고, 제2 단판적층재(20)를 제작하는 공정은 상온에서 진행하며, 10∼14㎏/㎠의 압력을 30∼60분 동안 가하게 된다. 제2 단판적층재(20)를 제작하는 공정에서는 접착제를 녹일 필요가 없으므로 상온에서 진행하며, 우레탄 접착제를 사용하기 때문에 단판적층재의 방수성이 향상되고 야외에서 비를 맞더라도 조경재에 박리현상이 발생하지 않게 된다.In step S3 of manufacturing the second veneer laminate 20, the first veneer laminate 10 is coated with an adhesive, and then the first veneer laminate 10 is placed in parallel with the neck direction of the first veneer laminate 10. By repeating the process of laminating the veneer laminate 10, the second veneer laminate 20 is manufactured by applying pressure at the top and bottom of the first veneer laminate laminated to the required thickness for a certain time (Fig. 3a). The adhesive 22 applied between the first veneer laminate 10 and the first veneer laminate in step S3 uses a urethane adhesive, and the process of manufacturing the second veneer laminate 20 proceeds at room temperature, A pressure of 10 to 14 kg/cm 2 is applied for 30 to 60 minutes. In the process of manufacturing the second veneer laminate 20, it is not necessary to melt the adhesive, so it proceeds at room temperature, and since the urethane adhesive is used, the waterproofness of the veneer laminate is improved, and even if it is exposed to rain outdoors, peeling does not occur on the landscape material. Will not be.

본 발명의 출원인은 제1 단판적층재(10)와 제1 단판적층재(10) 사이에 우레탄 접착제를 도포하여 접착시킨 제2 단판적층재(20)를 끓는 물에 4시간 침지시킨 후, 60℃에서 20시간을 건조시킨 다음, 다시 끓는 물에 4시간 침지시킨 후 60℃에서 20시간을 건조시키는 내수성과 박리 시험을 한 결과 단판적층재 사이에 박리현상이 전혀 나타나지 않았고 내수성에도 전혀 문제가 없음을 확인하였다. 하지만, 다른 접착제(에틸렌-비닐아세테이트 접착제 등)를 사용한 단판적층재는 모두 박리현상이 발생하였다.Applicants of the present invention apply a urethane adhesive between the first veneer laminate 10 and the first veneer laminate 10 to bond the second veneer laminate 20, which is then immersed in boiling water for 4 hours, 60 After drying for 20 hours at ℃, then immersing in boiling water for 4 hours and drying for 20 hours at 60 ℃ after performing a water resistance and peeling test, there was no peeling phenomenon between the veneer laminates and there was no problem in water resistance at all. Was confirmed. However, all single-plate laminates using other adhesives (such as ethylene-vinyl acetate adhesive) had a peeling phenomenon.

재단하는 단계인 S4 단계에서는 제1 단판적층재(10) 또는 제2 단판적층재(20)를 규격에 맞게 재단하게 된다. 통상적으로 단판적층재의 크기가 1,220㎜×2,440㎜ 정도이기 때문에 필요로 하는 크기(규격)와 형상의 조경재(25)로 재단하여 사용한다(도 4 참조). 단판적층재를 데크로 사용할 경우 사용되는 면은 목리방향 즉 섬유방향이 있는 면이 아니고 단판이 적층되면서 접착된 면을 사용하게 된다. 한편, 데크 표면에 미끄럼 방지용 논슬립 가공 등을 해야 하므로 재단한 단판적층재 가공시 두께가 축소되는 점을 감안하여, 단판적층재를 재단할 때는 필요로 하는 두께보다 3∼4㎜ 정도 두껍게 재단을 하는 것이 바람직하다.In step S4, which is a cutting step, the first veneer laminate 10 or the second veneer laminate 20 is cut according to the standard. Typically, the size of the single-plate laminate is about 1,220 mm × 2,440 mm, so it is cut and used as a landscape material 25 having a required size (standard) and shape (see Fig. 4). When the veneer laminate is used as a deck, the side used is not the side with the direction of the neck, that is, the fiber direction, but the side bonded while the veneer is laminated. On the other hand, in consideration of the fact that the thickness of the cut veneer laminate is reduced when processing the cut veneer laminate, since non-slip processing for anti-slip is required on the deck surface, when cutting the veneer laminate, it is necessary to cut it 3-4mm thicker than the required thickness. It is desirable.

단판적층재에 방부 기능을 부여하기 위해서는 재단하는 단계(S4)를 거친 후에 방부처리 하는 단계(S5)를 실행하는데, 방부처리는 가압식 방부처리를 하는 것이 바람직하다. 원목을 사용하는 천연데크는 가압식 방부처리가 어렵지만, 단판적층재를 사용한 데크는 가압식 방부처리가 가능하여 데크의 내부후성이 강화되는 장점이 있다.In order to impart an antiseptic function to the veneer laminate, the step of embalming (S5) is performed after the step of cutting (S4), and the embalming treatment is preferably a pressurized antiseptic treatment. Natural decks made of solid wood are difficult to be subjected to pressurized antiseptic treatment, but decks made of veneer laminates have the advantage of reinforcing the weather resistance of the deck by enabling pressurized antiseptic treatment.

오일스테인(oil stain)을 도장하는 단계인 S6 단계는 재단된 단판적층재의 표면에 유성 착색제를 도포하는 단계이다. 오일스테인은 단판적층재의 도색, 방부, 방충, 방수 등의 목적으로 칠하게 되는데, 현재 다양한 종류의 색상을 가진 오일스테인이 판매되고 있고, 오일스테인으로 마감처리를 하기 때문에 조경재에 다양한 색상을 구현할 수 있게 된다.Step S6, which is the step of applying oil stain, is a step of applying an oil-based colorant to the surface of the cut veneer laminate. Oil stains are painted for the purpose of painting, preservative, insect-repellent, and waterproofing of veneer laminates. Currently, oil stains with a variety of colors are on sale, and because they are finished with oil stains, various colors can be implemented in landscape materials. There will be.

지금까지 설명한 방법으로 제조된 조경재는, 넓은 규격(1,220㎜×2,440㎜)으로 1차 단판적층재(10)가 제조된 것을, 필요한 두께로 만들기 위하여 1차 단판적층재(10)를 필요한 만큼 적층시켜서 제2 단판적층재(20)를 제조하고, 넓고 두꺼운 제2 단판적층재를 필요로 하는 임의의 형상과 크기로 재단하여 사용하기 때문에 원목이나 합성목재로는 제작할 수 없는 형상과 크기로 조경재의 제작이 가능할 뿐만 아니라 원목이나 합성목재에 비해 가격면에서 훨씬 저렴하면서도 원목을 사용하지 않으므로 산림훼손을 줄일 수 있어서 환경친화적이다.The landscaping material manufactured by the method described so far is laminated as many as necessary to make the primary veneer laminate 10 in a wide standard (1,220mm×2,440mm) to the required thickness. To manufacture the second veneer laminate 20, and cut and use the wide and thick second veneer laminate in any shape and size required, so that the landscape material can not be manufactured with solid wood or synthetic wood. Not only can it be manufactured, but it is much cheaper in terms of price than solid wood or synthetic wood, and it is eco-friendly because it can reduce forest damage because it does not use solid wood.
