As a result, scratches (scratches) The present invention relates to a scratch resistant board having enhanced abrasion resistance and a method of manufacturing the scratch resistant board.

일반적으로 도마라 함은 음식물을 조리하고자 할 때 식재료를 절단하기 위해 사용하는 것이다.Generally, the term "cutting board" is used to cut food when it is desired to cook food.

통상적으로 도마는 나무재질로 제조되고 있으나 현대에는 기술의 발달로 인해 합성수지를 주 원료로 하는 플라스틱도마가 제공되고 있다.Generally, cutting boards are made of wood. However, due to the development of technology, plastic boards made of synthetic resin as a main raw material have been provided.

플라스틱 도마는 수분이 흡수하지 않는 장점이 있으나 요리시에 칼질을 하면 칼흠집(스크래치-Scratch)이 도마 표면에 발생하게되고, 그 칼흠집 사이로 세균이 번식하게되며, 김치,야채의 색소가 칼흠집 사이로 침투하면서 베어나게되어 도마의 변색이 촉진되는 문제점이 발생하고 있었다.
The plastic cutting board has the advantage of not absorbing moisture, but if it cuts during cooking, a knife scratch (scratch) will occur on the cutting surface of the cutting board, the bacteria will propagate through the knife scratches, So that discoloration of the board is accelerated.

등록특허 제 1167070호는 플라스틱도마 제조방법에 대한 종래기술로서,Patent No. 1167070 discloses a method for manufacturing a plastic cutting board,

열가소성 폴리우레탄, 꼬막 껍데기 분말 및 첨가제를 혼합한 후 압출기로 용융 압출하여 컴파운드를 형성시키는 단계;Mixing thermoplastic polyurethane, shell coat powder and additives, and melt-extruding the mixture with an extruder to form a compound;

상기 건조된 컴파운드를 사출성형하여 주방 도마를 형성시키는 단계를 포함하여 구성된다.And forming a kitchen board by injection molding the dried compound.

등록특허 제 1167070호는 폴리우레탄을 주원료로 하면서 꼬막 껍데기 분말과 첨가제를 혼합하여 컴파운드를 생성하고, 그 컴파운드를 사출성형하여 주방도마를 제조하는 것이다.Patent No. 1167070 discloses that a polyurethane is used as a main raw material and a shell is mixed with an additive to produce a compound, and the compound is injection-molded to produce a kitchen board.

즉, 종래기술은 폴리우레탄에 꼬막껍데기 분말을 첨가하여 플라스틱도마가 우수한 탄성을 갖도록 하면서 꼬막 껍데기가 갖는 항균기능과 탈취력에 의해 플라스틱도마가 자체적으로 항균력을 구비하도록 한 것이다.That is, according to the prior art, the plastic board is provided with antibacterial power by the antimicrobial function and the deodorizing power of the shell of the shell while adding the shell coat powder to the polyurethane so that the plastic board has excellent elasticity.

그러나, 종래기술 역시 플라스틱 도마 자체의 내마모성이 취약하여 칼질시 칼흠집이 도마에 발생하면서 칼흠집으로 음식물찌꺼기가 침투하고, 이에의해 칼흠집 발생부위에서 세균이 번식하게되는 문제점이 발생하고 있었다.However, the conventional art also has a problem that the abrasion resistance of the plastic board itself is poor, so that knife scratches are formed on the chopping block when the knife is cut, and the food scraps are penetrated by the knife scratches, thereby causing bacteria to breed in the knife scratching area.

또한, 종래기술은 칼흠집을 미연에 방지하지 못함에 따라 도마에 김치 또는 야채를 올려놓고 절단할 경우 김치 또는 야채의 색소가 칼흠집에 스며들게되어 도마의 색상이 변색되는 문제점이 발생하고 있었다.
In addition, since the prior art can not prevent knife scratches, when the kimchi or vegetables are placed on a cutting board, the coloring of the kimchi or vegetables is impregnated into the knife scratches, and the color of the cutting board is discolored.

따라서, 상기 문제점을 해결하기 위한 본 발명은 폴리에틸렌 67중량%, 폴리테트라플루오로에틸렌과 셀레니움을 혼합한 첨가제 32중량%, 분산제 1중량%를 개량하는 제 1 과정과; 제 1 과정에서 개량된 재료를 혼합탱크에 투입한 후 30분간 혼합하는 제 2 과정과; 혼합과정을 거친 재료를 사출기에 투입한 후 180℃~210℃의 온도를 유지하면서 사출하는 제 3 과정; 으로 구성하므로서, 플라스틱도마의 원재료인 폴리에틸렌의 밀도를 높여주면서 내마모성을 향상시키고, 낮은 마찰계수를 갖도록 하여 제조된 도마의 표면강도가 높아지고, 이에의해 도마 사용시 칼질을 하더라도 도마 표면에 스크래치(칼흠집)가 발생하지 않으면서 세균번식을 억제함은 물론 도마의 변색을 억제할 수 있도록 한 내마모성이 강화된 스크래치 방지도마 및 그 제조방법을 제공함을 목적으로 한다.

첨가제는 폴리테트라플루로오에틸렌(Poly Tetra Fluoro Ethylene)과 셀레니움(Selenium)을 혼합하여 사용한다.The additive is a mixture of PolyTetra Fluoro Ethylene and Selenium.

폴리테트라플루로오에틸렌(Poly Tetra Fluoro Ethylene)은 많은 작은 분자(단위체)들을 사슬이나 그물 형태로 화학결합시켜 만드는 커다란 분자로 이루어진, 유기 중합체 계열에 속하는 비가연성 불소수지 이다. Poly Tetra Fluoro Ethylene is a non-flammable fluoropolymer belonging to the organic polymer family, consisting of large molecules made by chemically bonding many small molecules (units) in a chain or net form.

이러한 폴리테트라플루로오에틸렌(Poly Tetra Fluoro Ethylene)은 열에 강하고, 마찰계수가 극히 낮은 특징이 있으며, 다음과 같은 특성을 갖는다.Such polytetrafluoroethylene is resistant to heat and has an extremely low coefficient of friction and has the following characteristics.

① 고도의 결정성 수지로 수축율이커 사출, 압출성형 가공이 가능하나, 투명성형품을 만들수 없다.① It is possible to extrude and extrude shrinkage rate with highly crystalline resin, but transparent molded products can not be made.

상기 설명과 같이 첨가제로 폴리테트라플루로오에틸렌(Poly Tetra Fluoro Ethylene)과 셀레니움(Selenium)을 혼합하는데, 폴리테트라플루로오에틸렌과 셀레니움을 7:3 또는 6:4의 비율로 혼합한다.As described above, PolyTetra Fluoro Ethylene and Selenium are mixed as an additive, and polytetrafluoroethylene and selenium are mixed at a ratio of 7: 3 or 6: 4.

한편, 본 발명에서는 분산제 1중량%가 첨가된다.In the present invention, 1% by weight of a dispersant is added.

분산제는 사출시 각 재료 분자들의 응집을 방지하며 사출성형 흐름 향상을 위해 첨가되며, 본 발명에서는 분산제로서 플라스티스 아디티브(Plastis Additive)를 사용하였다.The dispersant is added to improve the injection molding flow while preventing the aggregation of each material molecule at the time of injection. In the present invention, a plasticizer additive is used as a dispersant.

본 발명에 투입되는 첨가제와 분산제는 기본 원재료인 폴리에틸렌과 같은 고분자 구조를 갖는 재료를 투입하여 이형이 방지되도록 하며, 도마가 주방용품이므로 인체에 무해한 환경제품이어야 하기 때문에 첨가제와 분산제는 무독성 재료를 사용해야 한다.
The additive and dispersant to be added to the present invention should be a non-toxic material because the additive and the dispersant must be a harmless environment-friendly product because the cutting board is a kitchenware so that a material having a polymer structure such as polyethylene, do.

본 발명의 제조과정을 설명하면 다음과 같다.The manufacturing process of the present invention will be described as follows.

먼저, 재료를 개량한다.First, improve the material.

준비된 폴리에틸렌 67중량%, 폴리테트라플루오로에틸렌과 셀레니움을 혼합한 첨가제 32중량%, 분산제 1중량%를 개량하되, 첨가제는 폴리테트라플루오로에틸렌과 셀레니움을 7:3 또는 6:4로 혼합하여 구성한다.The polytetrafluoroethylene and selenium were mixed in a ratio of 7: 3 or 6: 4 to prepare 67% by weight of prepared polyethylene, 32% by weight of an additive mixed with polytetrafluoroethylene and selenium and 1% do.

첨가제를 32중량%로 한정하는 이유는 첨가제 투입량이 32중량%를 초과하거나 적어지게되면 물성이 변화하게되어 사출되는 도마의 형상이 변형되거나 원하는 내마모성을 획득하지 못하게 된다.The reason why the additive is limited to 32% by weight is that when the additive amount exceeds 32% by weight or less, the physical properties change and the shape of the ejected board is deformed or the desired abrasion resistance is not obtained.

상기와같이 재료의 개량이 완료되면 개량된 재료를 혼합탱크에 투입한 후 약 30분간 교반하여 혼합한다.After the improvement of the material is completed as described above, the modified material is put into a mixing tank and mixed for about 30 minutes with stirring.

혼합이 완료되면, 혼합된 재료를 사출기에 투입한 후 사출한다.When mixing is completed, the mixed material is injected into an injection machine and then injected.

사출할때 사출기의 온도가 180℃~210℃의 온도를 유지하도록 한다.When injecting, keep the temperature of the injection machine at 180 ~ 210 ℃.

사출하는 동안 180℃~210℃의 온도를 유지하지 못하면 사출물의 표면상태가 매끄럽지 못하게되므로, 상기 사출온도 180℃~210℃를 유지하는 것이 매우 중요하다.It is very important to maintain the injection temperature of 180 ° C to 210 ° C because the surface state of the injection molded article is not smooth unless the temperature of 180 ° C to 210 ° C is maintained during the injection molding.

사출이 완성되면 내마모성이 강화된 스크래치 방지도마가 완성된다.When the injection is completed, the anti-scratch board with improved abrasion resistance is completed.

완성된 스크래치 방지도마는 표면이 매끄러우면서 내마모성이 강화되어 칼질을 하여도 도마 표면에 스크래치가 발생하지 않게된다.The finished scratch resistant board has a smooth surface and enhanced abrasion resistance so that scratches do not occur on the surface of the cutting board even if the cutting is performed.

도마 표면에 스크래치가 발생하지 않게되면 세균번식을 근본적으로 억제할 수 있고, 또한 도마의 변색을 억제할 수 있게된다.
If scratches do not occur on the surface of the cutting board, the propagation of the germ can be fundamentally suppressed, and discoloration of the cutting board can be suppressed.
