Description

건축용 재생 합성수지 마감재 및 그 제작방법{Reproduction synthetic resin materials for a construction and a manufacturing method thereof}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin-

본 발명은 건축용 재생 합성수지 마감재 및 그 제작방법에 관한 것으로서, 더욱 상세하게는 폐합성수지를 재생하여 친환경적이고 제작비용을 절감시키고, 물성 결합력을 향상시킨 상용제를 통해 방수성 및 내구성을 향상시킨 건축용 재생 합성수지 마감재 및 그 제작방법에 관한 것이다.The present invention relates to a reclaimed synthetic resin finishing material for construction and a method of manufacturing the same. More particularly, the present invention relates to a synthetic resin recycled synthetic resin having improved waterproofness and durability through a recycled waste synthetic resin and environmentally friendly, And a method for manufacturing the same.

근래에 들어 건축물의 고급화 추세에 따라 벽면용 마감재로 자연석을 비롯한 인조석 패널이 널리 사용되고 있다.In recent years, natural stone and artificial stone panels are widely used as finishing materials for walls in accordance with the trend of high-grade buildings.

이러한 마감재의 부착방법으로서, 자연석이나 인조석에 고정볼트의 일부가 노출되도록 매립하고 고정볼트가 매립된 자연석이나 인조석을 거푸집에 넣은 후 고정볼트가 잠기도록 콘크리트를 타설하여 양생시킴으로써 건축물의 벽체나 옹벽구조물이 시공될 수 있는 것이다.As a method of attaching such a finishing material, a natural or artificial stone is buried such that a part of a fixing bolt is exposed, a natural stone or an artificial stone in which a fixing bolt is embedded is inserted into a mold, and concrete is placed and cured so that the fixing bolt is locked. This can be done.

이러한 건축물 벽체 시공방법은 『대한민국 등록번호 10-1646527』을 통해 개시된 바 있다.The method of constructing such a wall structure has been disclosed in Korean Registration No. 10-1646527.

하지만, 상기한 바와 같이 벽체의 마감재를 자연석이나 인조석과 같이 석재로 사용할 경우, 문양 및 색상 표시가 용이하게 이루어지기 어려운 문제가 있었다.However, when the finishing material of the wall is used as a stone such as a natural stone or an artificial stone as described above, there is a problem that it is difficult to easily display the pattern and the color.

즉, 주택의 경우 외관의 심미감을 높이는 것은 매우 중요한데, 전술한 바와 같이 마감재가 석재패널로 사용될 경우 다양한 심미감을 제공하기 어려운 문제가 있었던 것이다.In other words, it is very important to enhance the aesthetics of the exterior of the house. As described above, when the finishing material is used as the stone panel, it is difficult to provide various aesthetics.

물론, 상기한 문제점을 해결하기 위하여 『공개실용신안 2000-0005218』에 개시된 바와 같이, 목재를 이용한 마감패널을 마련하여 다양한 문양 등을 용이하게 새겨 심미감을 높일 수 있도록 한 기술이 개시되어 있다.Of course, in order to solve the above problems, a technique has been disclosed in which a finishing panel made of wood is provided as disclosed in " Open Utility Model No. 2000-0005218 "

하지만, 목재패널의 경우에는, 표면에 흠집이나 못구멍등의 상처가 발생되고 특히 시멘트 몰탈에 함유된 수분이 목재합판에 직접 접촉되어 흡수되므로 내구성이 약화되고 사용후 적층과정 등에서 파손되는 문제가 있었다.However, in the case of the wood panel, scratches or nail holes are formed on the surface, and in particular, the moisture contained in the cement mortar is absorbed directly in contact with the wood plywood, so that the durability is weakened and the post- .

또한, 이러한 흠집이 있는 목재 패널을 그대로 사용하면 양생된 콘크리트 벽체가 평활면을 가질 수 없고 외관상 깨끗하지 못하므로, 목재패널에 대한 유지보수 비용이 증가되는 문제가 있었다.In addition, if such a damaged wood panel is used as it is, the cured concrete wall can not have a smooth surface and is not apparently clean, thus increasing the maintenance cost for the wood panel.

또한, 부분적인 흠집을 표면처리하여 재생한 패널을 사용하더라도, 1회 사용만으로 다른 부분이 파손되는 경우도 많기 때문에, 목재패널이 가지고 있는 짧은 수명에 대한 문제점을 해소하기는 어려운 실정이다.In addition, even if a panel that has been partially reproduced by scratching is used, it is often difficult to solve the problem of the short life of the wood panel because the other part is broken only by one use.

물론, 목재대신 패널을 금속재로 제작할 수도 있으나, 금속패널은 목재패널에 비해 제작비용이 과다하게 소요되므로, 수급 균형을 맞추기 어려운 문제가 있었다.
Of course, the panel may be made of metal instead of wood, but the metal panel requires a lot of manufacturing cost compared with the wood panel, so that it is difficult to balance supply and demand.

이하, 첨부된 도 1을 참조하여 본 발명의 바람직한 실시예에 따른 건축용 재생 합성수지 마감재에 대하여 설명하도록 한다.Hereinafter, a recycled synthetic resin finishing material for construction according to a preferred embodiment of the present invention will be described with reference to FIG.

건축용 재생 합성수지 마감재는 폐합성수지로 만든 재생원료와 신소재, 그리고 물성 결합을 높이는 매개 물질인 상용제를 혼합하여 제작한 기술적 특징이 있다.The recycled synthetic resin finishing material for construction has a technical feature that is made by mixing regenerated raw materials made from waste synthetic resin, new materials, and commercial agents, which are intermediates for enhancing the physical properties.

이에 따라, 산업쓰레기를 이용하여 친환경적이면서도, 내구성, 흡음 및 방음, 방수성 등을 높이고 재질 특성상 가공 및 색상부여가 용이해짐에 따라 다양한 심미감을 용이하게 제공할 수 있게 된다. Accordingly, it is possible to easily provide a variety of aesthetics because it is eco-friendly by using industrial wastes, durability, sound absorption, soundproofing, waterproof and the like are improved, and processing and coloring are easy due to the characteristics of materials.

건축용 재생 합성수지 마감재는 도 1에 도시된 바와 같이 중간층(100)과, 상층(200)과, 하층(300)으로 구성된다.As shown in FIG. 1, the recycled synthetic resin finishing material for construction comprises an intermediate layer 100, an upper layer 200, and a lower layer 300.

각각의 층은 시트(sheet) 형태로 제작된 후, 압출 가공을 통해 하나의 마감재로 제작이 된다.Each layer is made in sheet form and then extruded into a single finish.

중간층(100)은 마감재의 중간을 구성하며, 재생원료를 주(主) 물질로 하여 제작이 된다.The intermediate layer 100 constitutes the middle of the finishing material, and is made of a regenerated raw material as a main material.

이때, 재생원료라 함은 폐합성수지를 가공하여 재생한 물질로서, 일반인들의 가정이나 산업현장에서 폐자원으로 처리되는 전선피복, 포장비닐 등을 펠릿(pellet) 형태로 가공한 것을 말한다.At this time, the term "regenerated raw material" refers to a material obtained by processing waste synthetic resin, which is processed into pellets in the form of electric wire covering, wrapping vinyl, etc., which are treated as waste resources in the home or industrial sites of the general public.

이때, 재생원료가 되는 폐합성수지의 주물질로는 폴리프로필렌(PP), 폴리에틸렌(PE), TPE(Thermo Plastic Elastomer), TPU(Thermo Plastic urethane), 폴리아미드(PA), 폴리카보네이트(PC) 등이 있다.At this time, as a main material of the waste synthetic resin to be a raw material for recycling, polypropylene (PP), polyethylene (PE), thermo plastic elastomer (TPE), thermo plastic urethane (TPU), polyamide (PA), polycarbonate .

이때, 중간층(100) 재료가 되는 재생원료는, 다양한 제품으로 사용되었던 여러 폐합성수지를 혼합하여 상기한 펠릿 형태로 가공되는데, 펠릿 가공 과정에서 폐합성수지들의 물성 결합력이 높아질 수 있도록 상용제가 더 추가된다.At this time, the recycled raw material to be the material of the intermediate layer 100 is processed into the above-mentioned pellet form by mixing various waste synthetic resins used as various products, and a commercial agent is added so that the physical bonding force of the waste synthetic resins can be increased during the pellet processing .

상용제는 물성 결합을 높이기 위한 매개물질로서, 아연과, 구연산과, LC왁스와, 발포제 혼합을 통해 마련된다.The compatibilizing agent is an intermediate material for enhancing the physical bonding, and is prepared by mixing zinc, citric acid, LC wax, and a foaming agent.

상기 상용제는 중간층(100)을 구성하는 폐합성수지를 비롯한 여러 물질 간에 물성 결합력을 높일 뿐만아니라, 중간층(100)과 상층(200), 중간층(100)과 하층(300) 간에 결합력을 높일 수 있다. The compatibilizing agent not only enhances the physical bonding force between various materials including waste synthetic resin constituting the intermediate layer 100 but also enhances the bonding force between the intermediate layer 100 and the upper layer 200 and between the intermediate layer 100 and the lower layer 300 .

이때, 상용제를 구성하는 각각의 물질 혼합비율은, 상용제 중량에 대하여, 아연 10~20중량%, 구연산 40~50중량%, LC왁스 20~30중량%, 발포제 10~20중량%임이 바람직하다.At this time, the mixing ratio of each material constituting the compatibilizer is preferably 10 to 20% by weight of zinc, 40 to 50% by weight of citric acid, 20 to 30% by weight of LC wax, and 10 to 20% by weight of a blowing agent, Do.

이때, 상용제에 무수말레인산(maleic acid)을 추가로 혼합하여 상용제의 물성 결합력을 더욱 높일 수도 있다.At this time, maleic anhydride may be further mixed with the compatibilizing agent to further increase the physical binding force of the compatibilizing agent.

이때, 무수말레인산과 다른 물질 간에 혼합 비율은 조절될 수 있다.At this time, the mixing ratio between maleic anhydride and other materials can be controlled.

이와 같이 마련된 상용제와 폐합성수지를 배합기에서 혼합하여 마감재의 중간층(100)을 구성하는 재생원료인 펠릿을 가공하게 된다.The commercial agent and the waste synthetic resin thus prepared are mixed in a blender to process the pellets as a raw material for regenerating the intermediate layer 100 of the finishing material.

이때, 상용제를 통해 여러 폐합성수지의 혼합 및 물성 결합은 더욱 높아질 수 있게 된다.At this time, the mixing and physical properties of the various waste synthetic resins can be further increased through the commercial agent.

한편, 중간층(100)에는 재생원료와 함께 필요에 따라 난연제를 혼합하여 방화기능을 높일 수 있다.On the other hand, in the intermediate layer 100, a flame retardant may be mixed with the regenerated raw material as required, thereby enhancing the fire protection function.

특히, 중간층(100)에 발포제를 혼합하여, 상기 중간층(100)을 발포 성형시킴으로써 공극이 형성되고 이와 같이 중간층(100)에 공극이 형성됨에 따라 방음 및 흡음 효율을 높일 수 있게 된다.Particularly, by mixing the foaming agent in the intermediate layer 100 and forming the voids by forming the intermediate layer 100 by foam molding, voids are formed in the intermediate layer 100, thereby enhancing soundproofing and sound absorption efficiency.

다음으로, 상층(200)과 하층(300)은 마감재의 표면을 구성하는 층으로서, 도 1 에 도시된 바와 중간층(100)의 상면과 저면에 각각 마련된다.Next, the upper layer 200 and the lower layer 300 are provided on the upper surface and the lower surface of the intermediate layer 100 as shown in Fig. 1, respectively, as layers constituting the surface of the finish material.

상층(200)과 하층(300)은 각각 신소재를 주(主)물질로 구성하며, 마감재의 내구성 및 방수성을 높인다.The upper layer 200 and the lower layer 300 each comprise a new material as a main material and enhance the durability and waterproofness of the finish material.

상층(200)과 하층(300)은 각각, 신소재와, 폐합성수지와, 상용제와, 강화제를 포함하여 구성된다.The upper layer 200 and the lower layer 300 each include a new material, a waste synthetic resin, a compatibilizer, and a reinforcing agent.

신소재는 폴리프로필렌(PP)과 폴리에틸렌(PE)로 마련됨이 바람직하며, 신소재 중량에 대하여, 폴리프로필렌 80~90중량%와 폴리에틸렌 10~20중량%의 비율로 혼합된다.The new material is preferably made of polypropylene (PP) and polyethylene (PE), and is mixed at a ratio of 80 to 90% by weight of polypropylene and 10 to 20% by weight of polyethylene relative to the weight of the new material.

신소재를 구성하는 폴리프로필렌은 경도가 높아 마감재의 강도 유지에 적합하고, 폴리에틸렌은 상대적으로 신축성이 높아 부러짐을 방지하는 특성이 있으므로 마감재 강성을 높일 수 있는 탁월한 효과가 있다.The polypropylene constituting the new material has a high hardness, which is suitable for maintaining the strength of the finishing material. The polyethylene has a relatively high elasticity to prevent breakage, and thus has an excellent effect of increasing the rigidity of the finish material.

그리고, 폐합성수지는 중간층을 구성하는 재생원료로 마련된다.The waste synthetic resin is provided as a regeneration raw material constituting the intermediate layer.

재생원료는 전술한 바와 같이, 여러 폐합성수지를 혼합하여 펠릿 형태로 가공한 것을 말한다.As described above, the recycled raw materials are obtained by mixing various waste synthetic resins and processing them into pellets.

그리고, 상용제는 재생원료의 물성 결합력을 높이기 위해 사용된 전술한 물질과 동일한 물질로 제공된다.The compatibilizing agent is provided in the same material as the above-mentioned material used for enhancing the physical bonding force of the regenerated raw material.

그리고, 강화제는 건설자재에 필요한 인장, 굴곡강도를 갖추기 위한 역할을 하는 물질이다.And reinforcing agent is a substance that plays a role in providing the tensile and flexural strength required for construction materials.

또한, 강화제는 마감재의 표면을 거칠게 함으로써, 미끄럼 방지를 위한 자재로 사용되게 할 수도 있다 The reinforcing agent may also be used as a material for anti-slip by roughening the surface of the finish

이때, 강화제는 유리섬유로 마련됨이 바람직하다.At this time, the reinforcing agent is preferably provided as glass fiber.

상기 유리섬유는 LFT(Long fiber reinforced themo plastic;장섬유)임이 더욱 바람직하다.It is more preferable that the glass fiber is long fiber reinforced themo plastic (LFT).

한편, 상기 상층(200)과 하층(300)을 각각 구성하는 물질의 혼합비율은, 상층(200)과 하층(300) 각각의 중량에 대하여, 신소재 60~80중량%, 재생원료(폐합성수지) 10~30중량%, 상용제 5~10중량%, 강화제 5중량%임이 바람직하다.
The mixing ratio of the material constituting each of the upper layer 200 and the lower layer 300 is 60 to 80% by weight based on the weight of each of the upper layer 200 and the lower layer 300, the recycled raw material (waste synthetic resin) 10 to 30% by weight, commercial grade 5 to 10% by weight, and reinforcing agent 5% by weight.

이하, 상기한 구성으로 이루어진 건축용 재생 합성수지 마감재 제작방법에 대하여 도 2를 더 참조하여 설명하도록 한다.Hereinafter, a method for manufacturing a reclaimed synthetic resin finishing material having the above-described construction will be described with reference to FIG.

일반인의 가정이나 산업현장으로부터 수집된 폐자재 중, 폐합성수지들을 물성별로 선별하는 작업을 실시한다.(S100)Among the waste materials collected from ordinary households or industrial sites, waste synthetic resins are sorted by physical properties (S100).

이후, 폐합성수지를 압축기로 압축한 후, 용융시설에 투입하여 용융시킨다.(S200)Thereafter, the waste synthetic resin is compressed by a compressor, and is then melted in a melting facility (S200)

이때, 폐합성수지들 간에 혼합 및 물성 결합이 잘 이루어질 수 있도록, 상용제를 더 혼합시킨다.At this time, a compatibilizing agent is further mixed so that mixing and physical coupling between waste synthetic resins can be performed well.

다음으로, 용융시설을 통해 습기가 유착된 용융물을 압출기에 투입시킨다.Next, the molten material to which the moisture is adhered through the melting facility is introduced into the extruder.

이 과정에서, 실린더에 배출공을 복수개 타공하여, 그 배출공을 통해 습기 및 가스가 배출되도록 한다.In this process, a plurality of discharge holes are formed in the cylinder, and moisture and gas are discharged through the discharge holes.

이때, 배출공을 통해 배출된 습기 및 가스는 스트레이너를 통해 불순물이 제거된다.(S300)At this time, the moisture and gas discharged through the discharge hole are removed from the impurities through the strainer (S300).

다음으로, 불순물이 제거된 용융물을 압출기를 통해 냉각수로로 압출시킨다.Next, the impurity-removed melt is extruded through the extruder into the cooling water furnace.

이때, 압출기를 통해 여러 갈래로 압출된 재생수지는 냉각수로에서 냉각되면서 3~4mm 입도를 갖는 펠릿으로 생산됨으로써, 폐합성수지를 이용한 재생원료가 마련된다.(S400)At this time, the regenerated water extruded through the extruder is produced in a pellet having a particle size of 3 to 4 mm while being cooled in a cooling water furnace, thereby providing a recycled raw material using waste synthetic resin (S400).

다음으로, 마감재를 구성하는 중간층을 제작한다.(S500)Next, an intermediate layer constituting the finishing material is manufactured (S500)

이를 위해, 펠릿 형태의 재생원료와 상용제를 배합기에서 혼합시킨다.For this purpose, the regenerated raw material in pellet form and compatibilizer are mixed in a blender.

이때, 방화재로 사용되는 자재를 생산한고자 하는 경우, 난연제를 더 추가하여 혼합시킨다.At this time, if the user wishes to produce a material used as a fireproofing, a flame retardant is further added and mixed.

이때, 재생원료에 포함된 상용제로 인해, 중간층(100)을 구성하는 각 물질들을 더욱 물성 결합이 높아지게 된다.At this time, due to the compatibilizing agent contained in the recycled raw material, the physical properties of each material constituting the intermediate layer 100 are further enhanced.

또한, 마감재의 방음 및 흡음 효율을 높이기 위해, 상기한 물질 외에 발포제를 추가하여, 중간층(100)을 발포 성형시키는 것이 바람직하다.Further, in order to increase the soundproofing and sound absorption efficiency of the finishing material, it is preferable to add a foaming agent in addition to the above-mentioned materials to foam-form the intermediate layer 100.

즉, 중간층(100)이 발포 성형됨에 따라, 중간층(100)에는 공극이 다수 형성됨으로서, 상기 공극으로 인해 마감재의 방음 및 흡음 효율성을 높일 수 있는 것이다.That is, as the intermediate layer 100 is foam-molded, a large number of voids are formed in the intermediate layer 100, so that the efficiency of soundproofing and sound absorption of the finish material can be increased due to the voids.

이후, 배합기를 통해 각 물질간에 혼합이 완료된 중간층(100)은 시트 형태로 제작이 완료된다.Thereafter, the intermediate layer 100, which has been mixed with each other through the blender, is completed in a sheet form.

다음으로, 상층과 하층을 각각 제작한다.(S600)Next, the upper layer and the lower layer are fabricated, respectively (S600)

이를 위해, 배합기에 펠릿 형태의 재생원료와, 신소재인 폴리프로필렌과 폴리에틸렌, 그리고 상용제를 넣어 혼합시킨다.For this purpose, a regenerated raw material in the form of pellets, polypropylene and polyethylene, and a compatibilizing agent, which are new materials, are mixed in a blender.

이때, 마감재의 표면 강화를 위해 장섬유(LFT)를 추가로 혼합시킨다.At this time, long fibers (LFT) are further mixed to strengthen the surface of the finishing material.

이때, 상용제로 인해 상층(200)과 하층(300) 각각을 구성하는 각 물질들은 물성 결합력이 더욱 높아지게 된다.At this time, the materials constituting each of the upper layer 200 and the lower layer 300 due to the compatibilizing agent have higher physical bonding force.

이후, 배합기를 통해 각 물질간에 혼합이 완료된 상층(200)과 하층(300)은 각각, 시트 형태로 제작이 완료된다.Thereafter, the upper layer 200 and the lower layer 300, which have been mixed with each other through the blender, are completed in a sheet form.

다음으로, 상기와 같이 시트 형태로 제작된 중간층(100)과 상층(200),하층(300)을 적층시킨후, 하나의 마감재로 압출 가공하는 작업을 실시한다.(S700)Next, the middle layer 100, the upper layer 200, and the lower layer 300, which are manufactured in the form of a sheet as described above, are laminated and extruded by a single finishing material. (S700)

이때, 통상의 마감재 두께를 12mm할 때, 중간층(100)의 두께는 9.6mm임이 바람직하고, 상층(200)과 하층(300)의 두께는 각각, 1.2mm임이 바람직하다.At this time, when the normal finishing material thickness is 12 mm, the thickness of the intermediate layer 100 is preferably 9.6 mm, and the thicknesses of the upper layer 200 and the lower layer 300 are 1.2 mm, respectively.

한편, 상기와 같은 두께를 갖는 중간층(100),상층(200),하층(300)이 적층되어 압출 가공됨에 따라, 도 1에 도시된 바와 같이 건축용 재생 합성수지 마감재의 제작이 완료된다.(S800)Meanwhile, the intermediate layer 100, the upper layer 200, and the lower layer 300 having the above-described thickness are laminated and extruded to complete the fabrication of the recycled synthetic resin finish material as shown in FIG.

이때, 중간층(100),상층(200),하층(300)이 압출 가공되는 과정에서, 각각의 층에는 동일물질인 상용제가 혼합되어 있으므로, 각 층간에 물성 결합력은 더욱 증대될 수 있게 된다.At this time, in the process of extrusion processing of the intermediate layer 100, the upper layer 200 and the lower layer 300, since the same material is mixed in each layer, the physical bonding force between the layers can be further increased.

한편, 상기와 같이 제작된 건축용 재생 합성수지 마감재를 대상으로 강도(强度)를 측정하였다.On the other hand, the strength of the recycled synthetic resin finishing material produced as described above was measured.

시험은 한국건설생활환경 시험연구원의 ASTM 규격을 이용하였으며, 시험은 제작된 마감재를 측정 장비에 올려 놓은 후, 가장 높은 피크 값에서 파손되었을 때 그 값을 측정하였다.The test was carried out using the ASTM standard of Korea Institute of Construction & Living Environment Test.
