Description

다수의 기포를 가진 연마포 {Abrasive paper having multiple cells}Abrasive paper having multiple cells

본 발명은 연마포에 관한것으로서, 특히 연마포의 표면에 다수의 기포(cell)The present invention relates to an abrasive cloth, in particular a plurality of cells (cell) on the surface of the abrasive cloth

(氣胞)가 형성되어 있고 그 속에 점착제가 스며들어 있어서 연마된 분말을 흡착하여 연마를 원활하고 신속하며 균일하고 청결하게 할 수 있는 연마포에 관한 것이다.The present invention relates to a polishing cloth having (iii) formed therein and an adhesive penetrated therein to adsorb the polished powder so that polishing can be smoothly, quickly, uniformly and cleanly.

현재까지의 연마포는 주로 종이류나 플라스틱 필름으로된 기재위에 단순히 연마제를 접착제로 부착시킨 것으로 구성되어 있어서 연마시에 연마포의 탄성이 부족하고 경직되어 연마가 균일하게 되기가 어렵고 또한 연마된 분말이 연마포와 함께 이동하면서 연마에 지장을 주게되므로 신속한 연마가 어렵고 연마를 방해하게 되어 연마가 원활하게 이루어지지 않으며 또한 연마분이 사방에 산재하여 청결하지 못할 뿐아니라 연마에 지장을 주기도 하고 공해의 요인이 되기도 하였다.Until now, the polishing cloth mainly consists of simply attaching an abrasive to the substrate made of paper or plastic film with an adhesive, so that the polishing cloth lacks elasticity and rigidity, making it difficult to make the polishing uniform. As it moves with the polishing cloth, it hinders the polishing, which makes it difficult to quickly polish and hinders the polishing.The polishing is not smooth, and the powder is scattered all over the place, which is not clean. It also became.

본 발명은 상기한 바와 같은 종래 연마포의 결점을 개선하여 연마가 원활하고 균일하게 되면서 연마분이 흩어지거나 산재하지 않아서 청결하게 연마할 수 있는 연마포를 제공코저 하는것으로서 이를 첨부도면을 참조하면서 상세히 설명하면 다음과 같다.The present invention improves the drawbacks of the conventional polishing cloth as described above to provide a polishing cloth that can be polished cleanly without being scattered or scattered while polishing is smooth and uniform, as described in detail with reference to the accompanying drawings. Is as follows.

연마포의 기재(6)위에 폴리우레탄 수지를 도포하여 다수의 기포(1)를 갖도록 발포하여 발포층(5)을 형성하거나, 상기 기재위에 다수의 기포(1)를 갖도록 발포된 폴리우레탄 필름을 적층하여 발포층(5)를 형성하고 상기 다수의 기포(1)가 형성된 폴리우레탄 발포층(5)에 접착제와 연마제의 혼합물을 도포하여 연마제 혼합물층(3)을 일정두께로 형성하거나, 상기 발포층(5)에 먼저 점착제를 도포하여 그 점착제가 기포(cell)내로 스며들어 점착제층(2)이 형성되게 한 다음 그 위에 접착제와 연마제의 혼합물을 도포하여 연마제 혼합물층(3)을 일정두께로 형성한 것으로 구성된다.Applying a polyurethane resin on the substrate 6 of the polishing cloth and foaming to have a plurality of bubbles (1) to form a foam layer (5), or a polyurethane film foamed to have a plurality of bubbles (1) on the substrate By laminating to form a foam layer (5) and applying a mixture of an adhesive and an abrasive to the polyurethane foam layer (5) on which the plurality of bubbles (1) is formed to form an abrasive mixture layer (3) to a predetermined thickness, or the foam An adhesive is first applied to the layer 5 so that the adhesive penetrates into the cells to form an adhesive layer 2, and then a mixture of the adhesive and the abrasive is applied thereon to make the abrasive mixture layer 3 to a certain thickness. It consists of what was formed.

상기에서 연마포의 기재는 폴리에스텔수지(PET), 폴리프로필렌 수지(PP), 폴리에틸렌 수지(PE)로 된 플라스틱 필름, 직포 또 부직포 중에서 선택된 어느하나로 할 수 있다.The substrate of the polishing cloth may be any one selected from polyester resin (PET), polypropylene resin (PP), plastic film made of polyethylene resin (PE), woven fabric or nonwoven fabric.

상기에서 접착제는 관용되는 접착제중 어느것도 가능하며, 예를 들면 고무계 접착제로는 천연 고무(NR), 이소프렌 고무(IR), 스틸렌부타디엔 고무(SBR), 스틸렌부타디엔 블럭 공중합체(SBS), 스틸렌이소프렌 블럭 공중합체(SIS), 부틸 고무, 폴리이소부틸렌, 크라프트 고무, 재생고무 등을 주재료로한 접착제들 중에서 선택 사용할 수 있다.The adhesive may be any of conventional adhesives. For example, the rubber adhesive may include natural rubber (NR), isoprene rubber (IR), styrene butadiene rubber (SBR), styrene butadiene block copolymer (SBS), and styrene isoprene. Block copolymer (SIS), butyl rubber, polyisobutylene, kraft rubber, recycled rubber and the like can be selected and used as the main material.

상기에서 접착제는 관용되는 접착제 어느것이든 가능하며, 예컨데 폴리우레탄계 접착제, 페놀계 접착제, 고무계 접착제 및 아크릴계 접착제 중에서 선택 사용될 수 있다.The adhesive may be any conventional adhesive, and may be selected from, for example, a polyurethane adhesive, a phenol adhesive, a rubber adhesive, and an acrylic adhesive.

상기에서 연마제는 관용되고 있는 산화알루미늄(Al2O3)실리콘 카마이드 (SiC), 산화철(Fe2O3), 산화크롬(Cr2O3), 수산화 알루미늄(Al2(OH)3) 등이 사용될 수 있다.In the above-described abrasives, aluminum oxide (Al 2 O 3 ) silicon carbide (SiC), iron oxide (Fe 2 O 3 ), chromium oxide (Cr 2 O 3 ), aluminum hydroxide (Al 2 (OH) 3 ), and the like are commonly used. This can be used.

이상과 같이 구성되는 본발명 연마포는 연마대상물체를 연마시에 연마된 연마분이 발생과 동시에 연마포의 기포(cell) 내로 스며들게 되어 연마분을 연마와 동시에 청소하게 되며 더욱이 기포(1)내에 점착제층(2)이 형성되어 있을 경우에는 연마분이 그 점착제에 흡수,부착되게 되므로 연마대상체의 표면에는 연마분이 산재됨이 없이 쾌적한 상태에서 연마가 가능하게 되므로 공해방지 효과가 있음은 물론이고 연마분이 연마대상체 표면에 산재되지 않으므로 연마분에 의해 연마에 방해됨이 없기 때문에 연마가 균일하고 원활하게 되는 장점이 있으며 또한 발포층(5)의 탄성에 의하여 굴곡이 지지 않게 균일한 연마가 가능하게 되는 특징도 있고, 또한 상기 접착제를 도포하지 않았을 경우에는 연마포를 신장시켜 기포(1)의 입구가 벌어지게 한 상태에서 세척하게되면 기포(1)내로 빨려들어간 연마분이 세척되므로 연마포를 건조시켜 재사용도 가능하다.The abrasive cloth of the present invention constituted as described above causes the abrasive powder generated upon polishing the object to be polished to penetrate into the cell of the abrasive cloth to clean the abrasive powder at the same time as polishing, and furthermore, the pressure-sensitive adhesive layer in the foam 1 When (2) is formed, the abrasive powder is absorbed and adhered to the pressure-sensitive adhesive, so that the surface of the object to be polished can be polished in a comfortable state without scattering the abrasive powder, thereby preventing pollution and of course the abrasive powder. Since it is not interspersed on the surface, there is an advantage that the polishing is uniform and smooth because it is not hindered by the polishing powder, and there is also a feature that enables uniform polishing without bending due to the elasticity of the foam layer 5, In addition, when the adhesive is not applied, the abrasive cloth is stretched so that the inlet of the bubble 1 is opened. If the chuck is sucked into the bubble (1), the abrasive powder is washed, so that the abrasive cloth can be dried and reused.

본 발명 연마포는 발포층(5)에 다수의 기포(1)가 형성되고 또 점착제가 그 기포속에 내제되어 있기도 하여 연마와 동시에 연마분을 흡착하여 흩어지지 않게 하므로 균일하고 원활하며 쾌적하고 능률적인 연마를 할 수 있는 효과가 있다.In the abrasive cloth of the present invention, a plurality of bubbles 1 are formed in the foam layer 5, and an adhesive is internally contained in the bubbles, so that polishing and adsorption of abrasive powder are prevented from being scattered, so that polishing is uniform, smooth, comfortable and efficient. It can be effective.
