Description
본 발명은 파레트에 관한 것으로서, 보다 상세하게는 파레트의 물성을 개선하여 강도와 내구성을 향상시킨 파레트에 관한 것이다.
BACKGROUND OF THE
일반적으로, 파레트는 정방형상으로 형성되어 생산된 제품을 적재하여 운반하거나 보관하는데 사용되고, 제품의 물류과정이나 수출 시 제품을 안정된 상태로 받쳐주는 역할을 한다.Generally, a pallet is formed in a square shape and is used to carry or store the produced product, and serves to support the product in a stable state during the logistics process or export.
이러한 파레트는 여러 종류의 파레트가 사용되어 왔으며, 파레트를 형성하는 재질에 따라 분류되는 바, 목재로 형성된 목재 파레트, 플라스틱 재질로 형성된 플라스틱 파레트, 중량제품을 적재하는데 사용되는 금속재질로 형성된 철재 파레트, 경량제품을 적재하는데 사용되는 종이재질로 형성된 종이 파레트, 스폰지나 스티로폼 등으로 형성된 발포 파레트 등으로 구분된다.Such a pallet has been used in various kinds of pallets and is classified according to the material forming the pallet. The pallet is classified into a wooden pallet made of wood, a plastic pallet made of plastic material, a steel pallet made of a metal material used to load heavy products, A paper pallet formed of a paper material used for loading a lightweight product, and a foam pallet formed of sponge or styrofoam.
이러한 파레트는 그 특성상 중량제품을 장기간 적재한 상태에서 이동하거나 보관하는 경우가 많기 때문에, 대부분 목재나 플라스틱 파레트가 주종을 이루고 있는 실정이다.
Such a pallet is often moved or stored in a state in which a heavy product is loaded for a long period of time, and therefore, most of the pallets are made of wood or plastic pallets.
하지만, 이와 같은 종래의 파레트는 다음과 같은 문제점을 안고 있다.However, such a conventional pallet has the following problems.
목재 파레트는 날로 목재 자원이 고갈되어 가고 있으며, 목재에 기생하는 해충이 함께 이동하기 때문에, 별도의 방균 및 방충 처리를 함으로써 원가가 상승되고, 각국에서 목재 파레트의 사용과 수입을 금지하고 있으며, 수분에 취약한 특성으로 인하여 현재는 그 사용이 급격하게 줄고 있는 실정이다.Wood pallets are becoming depleted in the wood resources and the parasitic insects go along with the wood. Therefore, the costs are raised by separate sterilization and insect treatment, and the use and import of the wooden pallets are prohibited in each country. Because of its vulnerability to the use of the current situation is a drastic reduction in use.
플라스틱 파레트는 강도가 높고 수분에 의한 영향을 받지 않으나, 내구성 향상을 위해 중량이 무거워지는 단점이 있으며, 고가이기 때문에 가격 경쟁력이 없는 단점이 있다.The plastic pallet has a high strength and is not affected by moisture, but it is disadvantageous in that it has a disadvantage that it is heavy in weight in order to improve its durability and is not cost competitive because it is expensive.
철재 파레트는 파레트의 각 구성품을 용접이나 많은 수의 피스 볼트(piece bolt)로 고정하여야 함으로써 제작 작업이 용이하지 못하고, 피스 볼트의 고정위치가 누락된 상태에서 파레트가 완성되는 경우가 많아 파레트 자체가 불량품이 되고 내구성이 떨어지게 되는 문제점이 있다.The steel pallet is required to be fixed by welding or a large number of piece bolts, so that it is not easy to manufacture the pallet. In many cases, the pallet is completed in a state where the fixing position of the piece bolts is missing. There is a problem that it becomes defective and durability is deteriorated.
그리고, 종이 파레트나 발포 파레트는 전술한 파레트에 비해 내구성이 크게 떨어져 비틀림현상 때문에 장시간 사용할 수 없는 문제점이 있다.
In addition, the paper pallet and the foam pallet have a problem that the durability is greatly increased as compared with the pallet described above, so that the paper pallet and the foam pallet can not be used for a long time because of the twist phenomenon.
이에, 본 발명은 전술한 바와 같은 문제점을 해결하기 위해 안출된 것으로, 파레트를 수지와, 질석 또는 펄라이트, 안료, 활성제, 발포제로 형성함으로써 파레트의 강도와 내구성을 향상시킬 수 있도록 한 파레트를 제공하는데 그 목적이 있다.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a pallet which can improve pallet strength and durability by forming pallet with resin, vermiculite or perlite, pigment, activator and foaming agent It has its purpose.
상술한 목적은, 50∼80중량％의 수지와, 10∼50중량％의 질석, 0.1∼3중량％의 안료, 0.02∼0.1중량％의 활성제, 1∼5중량％의 발포제가 혼합되어 형성되는 파레트에 의해 달성된다.The above-described object is achieved by mixing 50 to 80% by weight of a resin with 10 to 50% by weight of vermiculite, 0.1 to 3% by weight of pigment, 0.02 to 0.1% by weight of active agent and 1 to 5% It is accomplished by pallet.
또, 상술한 목적은, 50∼70중량％의 수지와, 10∼40중량％의 유리섬유, 10∼30중량％의 질석, 0.1∼3중량％의 안료, 0.02∼0.1중량％의 활성제, 1∼5중량％의 발포제가 혼합되어 형성되는 파레트에 의해서도 달성된다.The above-mentioned object is also achieved by a resin composition comprising 50 to 70% by weight of a resin, 10 to 40% by weight of glass fibers, 10 to 30% by weight of vermiculite, 0.1 to 3% by weight of pigment, 0.02 to 0.1% To 5% by weight of a foaming agent are mixed and formed.
그리고, 수지는 폴리프로필렌 또는 폴리에틸렌 또는 페트(Pet)와 폴리에틸렌의 혼합물 또는 폴리뷰틸렌테레프랄레이트(Polybutylene Terephthalate) 중 선택된 어느 하나로 구성되고, 이러한 수지는 재생 수지로 형성됨이 바람직하다.
The resin is preferably composed of any one selected from the group consisting of polypropylene or polyethylene or a mixture of PET and polyethylene or polybutylene terephthalate, and the resin is preferably formed from a recycled resin.
본 발명의 파레트에 따르면, 수지와, 질석 또는 펄라이트, 안료, 활성제, 발포제를 포함하는 파레트를 형성함으로써 수분에 의한 부식의 우려가 없고, 경량화 뿐 아니라 가격을 낮출 수 있으며, 파레트의 강도와 내구성을 향상시키며, 항균력과 항곰팡이성이 있어 물류창고 장기 사용 시 위생적인 장점이 있다.

And it has hygienic advantage in long - term use of logistics warehouse due to its antibacterial and antifungal properties.
도 1은 본 발명을 설명하기 위한 파레트 중 플라스틱 파레트를 일례로 예시한 도면이다.1 is a view illustrating an example of a plastic pallet in a pallet for explaining the present invention.
이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
본 발명의 파레트는 수지와, 질석 또는 펄라이트, 안료, 활성제, 발포제가 혼합되어 형성된다.The pallet of the present invention is formed by mixing a resin, vermiculite or perlite, a pigment, an activator, and a foaming agent.
수지는 폴리프로필렌(PP : Polypropylene) 또는 폴리에틸렌(PE : Polyethylene) 또는 페트(Pet)와 폴리에틸렌의 혼합물 또는 폴리뷰틸렌테레프랄레이트(Polybutylene Terephthalate) 중 선택된 어느 하나로 구성된다.The resin is composed of any one selected from polypropylene (PP) or polyethylene (PE) or a mixture of PET and polyethylene or polybutylene terephthalate.
이러한 수지는 무정형(無定形)의 고체로서, 물에 녹지 않고, 강도가 크며, 전기나 열이 통하지 않는 특징을 갖는다. 따라서, 본 발명의 파레트는 대부분이 수지로 형성됨으로써 큰 강도와 내구성을 갖게 된다.Such a resin is an amorphous solid, has a characteristic that it does not dissolve in water, has a high strength, and does not conduct electricity or heat. Therefore, the pallet of the present invention is largely formed of resin, so that it has high strength and durability.
이와 같은 수지는 재생수지를 사용한 것으로, 일상생활에서 버려지는 폐수지를 재활용하므로 친환경적이고, 새것의 수지를 사용할 때와 동일한 강도와 내구성을 가지면서도 원가를 절감시킬 수 있게 된다. 또, 전술한 수지는 신재(새로운 수지) 또는 재생 수지를 일정 비율 즉 2:8의 비율로 혼합하여 사용할 수도 있고, 이와 같은 수지는 대부분이 재생 수지로서 전술한 수지와 동일한 장점을 가지게 된다.Such a resin uses recycled resin, which is environmentally friendly because it recycles wasted resin that is discarded in daily life, and it is possible to reduce the cost while having the same strength and durability as when using a new resin. The above-mentioned resin may be mixed with a new material (new resin) or a recycled resin at a ratio of 2: 8, and most of these resins have the same advantages as the above-mentioned resins as recycled resins.
그리고, 질석(또는 펄라이트)은 다공질(多孔質)로서 흡수능력이 좋아서 내열재료 및 방음재(防音材)로도 널리 이용된다. 특히, 파레트를 구성하는 조성물에 질석 또는 펄라이트를 혼합함으로써 파레트의 강도와 내구성을 증대시킬 수 있고, 항균효과가 뛰어나 곰팡이 발생 등을 방지할 수 있게 된다.Further, vermiculite (or pearlite) is porous and widely used as a heat-resistant material and a soundproofing material because of its good absorption ability. Particularly, by mixing vermiculite or pearlite with the composition constituting the pallet, it is possible to increase the strength and durability of the pallet, and the antimicrobial effect is excellent, so that mold generation can be prevented.
안료는 파레트의 미감 또는 식별 기능을 부여하기 위한 것으로, 무기 안료가 사용되는 것이 바람직하다. 이러한 무기 안료로는 적색 산화철, 황색 산화철, 산화크롬(CrO3), 자색 산화철, 흑색 산화철(카본 블랙) 등을 포함할 수 있고, 파레트를 구성하는 다른 소재와 섞어서 착색하여 파레트의 색상을 결정한다.The pigment is for imparting an aesthetic or identification function of the pallet, and preferably an inorganic pigment is used. These inorganic pigments may include red iron oxide, yellow iron oxide, chromium oxide (CrO3), purple iron oxide, black iron oxide (carbon black), etc. and mixed with other materials constituting the pallet to color them to determine the color of the pallet.
활성제는 통상의 왁스로서 파레트를 구성하는 소재를 혼합할 때 질석 등의 돌가루 등이 잘 미끄러지도록 하여 잘 섞이도록 한다.The active agent is a conventional wax such that stone powder such as vermiculite slips well when the material constituting the pallet is mixed.
발포제는 파레트를 구성하는 수지를 비롯한 각 소재 등과 배합되어 수지를 발포시킴으로써 파레트의 크기와 부피를 결정하는 소재이다.The foaming agent is a material that determines the size and volume of the pallet by blending the resin with each material including the resin constituting the pallet, thereby foaming the resin.
따라서, 이와 같은 소재들로 성형되는 파레트는 큰 강도와 내구성을 가질 뿐 아니라 친환경적이고, 생산원가가 절감되는 장점이 있다.Accordingly, the pallet formed from such materials has an advantage of not only having high strength and durability but also being environmentally friendly, and reducing production cost.
게다가, 상기와 같은 파레트를 구성하는 소재들에다가 유리섬유를 더 혼합하여 주면, 고강도의 파레트를 형성할 수 있게 된다.In addition, if glass fibers are further mixed with the materials constituting the pallet as described above, a pallet of high strength can be formed.
유리섬유는 규산염을 주성분으로 하는 유리를 용융 가공하여 섬유 모양으로 가공한 것으로, 글라스 파이버 또는 글라스 울이라고도 한다. 이러한 유리섬유는 파레트의 강도와 내구성을 증대시킬 뿐 아니라 파레트의 휨과 수축을 방지할 수 있다.
The glass fiber is a glass fiber mainly made of silicate and processed into a fiber shape by melt processing, and may be referred to as glass fiber or glass wool. This glass fiber not only increases the strength and durability of the pallet but also can prevent the pallet from bending and shrinking.
이하, 본 발명의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명을 설명하기 위한 파레트 중 플라스틱 파레트를 일례로 예시한 도면이다.1 is a view illustrating an example of a plastic pallet in a pallet for explaining the present invention.
[실시예 1][Example 1]
본 실시예에 따른 파레트(1)는 50∼80중량％의 수지와, 10∼50중량％의 질석(또는 펄라이트), 0.1∼3중량％의 안료, 0.02∼0.1중량％의 활성제, 1∼5중량％의 발포제가 혼합되어 형성된다.The
보다 바람직하게는 61.9중량％의 수지와, 30중량％의 질석(또는 펄라이트)과, 3중량％의 안료와, 0.1중량％의 활성제와, 5중량％의 발포제를 혼합하여 첨부도면 도 1에서와 같은 파레트(1)를 제조한다.More preferably, 61.9% by weight of resin, 30% by weight of vermiculite (or perlite), 3% by weight of pigment, 0.1% by weight of active agent and 5% To produce the same pallet (1).
한편, 수지는 파레트(1)를 구성하는 주 소재로서, 50중량％ 미만이면 수지의 함량이 너무 적어 파레트(1)의 강도와 내구성을 일정하게 유지할 수 없고, 80중량％를 초과하면 수지 이외의 다른 소재들의 함량이 너무 낮아져 다른 소재들의 특성을 살릴 수 없게 된다.On the other hand, when the resin is less than 50% by weight, the content of the resin is too small to maintain the strength and durability of the
그리고, 이러한 수지는 폴리프로필렌 또는 폴리에틸렌 또는 페트와 폴리에틸렌의 혼합물 또는 폴리뷰틸렌테레프랄레이트 중 선택된 어느 하나로 구성되고, 이와 같은 수지는 재생 수지로 구성된다. 따라서, 이와 같은 수지가 재생 수지로 구성됨으로써 일상생활에서 버려지는 폐수지를 재활용하므로 친환경적이고, 새것의 수지를 사용할 때와 동일한 강도와 내구성을 가지면서도 원가를 절감시킬 수 있게 된다.Such a resin is composed of any one selected from polypropylene or polyethylene or a mixture of PET and polyethylene or polybutylene terephthalate, and such resin is composed of a recycled resin. Therefore, since such resin is constituted by recycled resin, waste plastic discharged in daily life is recycled, and it is environmentally friendly, and it is possible to reduce the cost while having the same strength and durability as when using a new resin.
질석 또는 펄라이트는 파레트(1)의 강도를 증대시킬 뿐 아니라 항균성을 갖는 소재로서, 10중량％ 미만이면 항균성이 미비해지고, 50중량％를 초과하면 상대적으로 수지의 함량이 50중량％ 미만으로 줄어들게 되어 파레트(1)의 강도와 내구성을 유지할 수 없게 된다.The vermiculite or pearlite not only increases the strength of the
그리고, 안료는 도 1에서와 같이 노란색을 갖는 무기안료로서, 그 혼합량이 0.1중량％ 미만이면 원하는 색상을 낼 수 없고, 3량％를 초과하면 기타 다른 소재의 혼합량이 줄어들게 되어 파레트(1)의 강도와 내구성 유지에 많은 어려움을 초래하게 된다.As shown in FIG. 1, the pigment is an inorganic pigment having a yellow color. When the amount of the pigment is less than 0.1% by weight, a desired color can not be obtained. When the amount exceeds 3% by weight, It is difficult to maintain strength and durability.
활성제는 왁스로서, 그 혼합량이 0.02중량％ 미만이면 각 소재들이 잘 혼합되지 못하고, 0.1중량％를 초과하면 파레트(1)의 표면장력이 떨어져 파레트(1)에 적재된 물품이 미끄러져 떨어질 수 있게 된다.If the amount of the activator is less than 0.02 wt%, the respective materials can not be mixed well. If the amount of the activator is more than 0.1 wt%, the surface tension of the
발포제의 혼합량이 1중량％ 미만이면 발포효율이 떨어지고, 5중량％를 초과하면 과도한 발포로 인해 성형된 파레트(1)의 강도와 내구성이 떨어지게 된다.If the blending amount of the foaming agent is less than 1 wt%, the foaming efficiency decreases. If the blending amount exceeds 5 wt%, the strength and durability of the molded
따라서, 상기와 같은 조성물로 혼합되어 제조된 첨부도면 도 1의 파레트(1)는 우수한 강도와 내구성, 표면 경도, 취성 등을 갖는다.
Therefore, the
[실시예 2][Example 2]
전술한 실시예 1과 동일한 부분에 대해서는 동일한 부호를 부여하고, 중복되는 설명은 생략한다.The same reference numerals are given to the same parts as those in the first embodiment, and redundant explanations are omitted.
본 실시예 2의 파레트(1)는 전술한 실시예 1의 조성물에다가 유리섬유를 더 혼합하여 제조한 것으로, 고강도의 파레트이다.The
즉, 본 실시예 2의 파레트(1)는 50∼70중량％의 수지와, 10∼40중량％의 유리섬유, 10∼30중량％의 질석, 0.1∼3량％의 안료, 0.02∼0.1중량％의 활성제, 1∼5중량％의 발포제가 혼합되어 형성된다.That is, the
한편, 보다 바람직하게는 57.02중량％의 수지와, 20중량％의 유리섬유와, 14.88중량％의 질석과, 3중량％의 안료와, 0.1중량％의 활성제와, 5중량％의 발포제를 혼합하여 첨부도면 도 1에서와 같은 파레트(1)를 제조한다.More preferably, 57.02 wt% of resin, 20 wt% of glass fiber, 14.88 wt% of vermiculite, 3 wt% of pigment, 0.1 wt% of active agent and 5 wt% of blowing agent are mixed The
여기서, 전술한 실시예와 다른 부분은 수지의 함량과 유리섬유가 혼합된 것으로, 수지의 최대치 함량이 전술한 실시예 1보다 작아졌으나, 이는 새로이 추가되는 유리섬유로서 상호 보완할 수 있다.Here, the difference from the above-mentioned embodiment is that the content of the resin and the glass fiber are mixed, and the maximum content of the resin is smaller than that of Example 1, but this can be complemented by newly added glass fiber.
이와 같이 추가된 유리섬유는 수지와 더불어서 파레트(1)의 강도와 내구성을 향상시키는 한편 휨과 수축을 방지하는 소재로서, 유리섬유의 혼합량이 10중량％ 미만이면 수지의 함량이 줄어들었음에도 불구하고 유리섬유의 함량이 너무 적어 파레트(1)의 강도와 내구성을 유지할 수 없을 뿐 아니라 파레트(1)의 휨 강도와 수축 강도 역시도 유지할 수 없게 되고, 40중량％를 초과하면 수지와 유리섬유 이외의 다른 소재들의 함량이 너무 낮아져 다른 소재들의 특성을 살릴 수 없게 된다.
The added glass fiber is a material for improving the strength and durability of the
