본 발명에 따르면 오픈셀(Open cell)로 형성된 폴리비닐 아세탈 스폰지에 연마 기능을 갖는 연마분을 합성한 후 성형하므로써 흡수 및 흡착력이 강한 함수성 스폰지에 연마 기능을 갖는 재질을 일체로 형성되도록 한 것을 특징으로 하는 다기능 함수성 연마스폰지를 제공한다.According to the present invention, by synthesizing and molding the abrasive powder having a polishing function on a polyvinyl acetal sponge formed of an open cell, a material having a polishing function is integrally formed on a functional sponge having strong absorption and adsorption power. A multifunctional water-based abrasive sponge is provided.

본 발명은 폴리비닐 아세탈 스폰지를 이용한 함수성 연마스폰지의 제조방법에 관한 것으로서, 먼저 폴리비닐 아세탈 스폰지를 이용한 함수성 연마스폰지의 특성 및 제조방법을 설명하고자 한다.The present invention relates to a method for manufacturing a water-based abrasive sponge using a polyvinyl acetal sponge, and firstly, a characteristic and a method of manufacturing a water-based abrasive sponge using a polyvinyl acetal sponge will be described.

폴리비닐 아세탈 스폰지는 다른 합성수지 스폰지에 비해 비교적 강한 흡수력과 흡착력을 가지고 있기 때문에 필터나 세척용구 등과 같은 공업용도로 많이 사용되고 있다. 이러한 폴리비닐 아세탈 스폰지는 폴리비닐 알콜 분말을 물과 함께 전분 덱스트린 등의 가용성물질 및 포르말린을 혼합하는 제1혼합공정(10)과 상기 혼합물을 가열, 용융시켜 혼합물을 졸로 만드는 1차가열용융공정(20)과 상기 1차 가열한 혼합물에 산을 혼합하는 제2혼합공정(30)과 열반응으로 폴리비닐 알콜이 아세탈화되며 전분 및 덱스트린이 가수분해되어 오픈셀(b)을 형성하는 2차가열반응공정(40) 후에 상기 폼을 물에 접촉시켜 가수분해된 전분과 덱스트린을 용융시키는 가용성물질 용출공정(50)을 거쳐 함수성 연마스폰지가 제조 된다.Polyvinyl acetal sponge has a relatively strong absorption and adsorption power compared to other synthetic resin sponges, so it is widely used in industrial applications such as filters and cleaning equipment. The polyvinyl acetal sponge is a first mixing step 10 of mixing polyvinyl alcohol powder with water, a soluble material such as starch dextrin, and formalin, and a primary heating melting step of heating and melting the mixture to make a sol. 20) and a second heating step of mixing an acid to the first heated mixture and a second reaction in which a polyvinyl alcohol is acetalized by thermal reaction and starch and dextrin are hydrolyzed to form an open cell (b). After the reaction process 40, the foam is brought into contact with water, and a hydrous abrasive sponge is prepared through a soluble material dissolution process 50 for melting the hydrolyzed starch and dextrin.

이에 폴리비닐 알콜을 이용한 함수성 연마스폰지는 상기한 폴리비닐 아세탈 스폰지의 제조공정에서 1차혼합공정(10)과 1차가열용융공정(20)을 거친 졸에 그린 실리콘 카바이드(Green silicon carbide), 블랙 실리콘 카바이드(Black silicon carbide), 브라운 알루미늄 옥사이드(Brown aluminum oxide), 화이트 알루미늄 옥사이드(White aluminum oxide) 또는 토사(Tosa) 등의 연마분 중에서 적어도 하나 이상을 선택적으로 기능에 따른 연마분의 입자 크기를 선택하여 혼합하는데 용도에 따라 폴리비닐 알콜의 혼합액의 10-70 중량% 정도를 혼합 한다(31),The water-based abrasive sponge using polyvinyl alcohol, green silicon carbide (Green silicon carbide) in the sol through the first mixing step (10) and the first heating melting step (20) in the manufacturing process of the polyvinyl acetal sponge, Select at least one or more of the abrasive powders such as black silicon carbide, brown aluminum oxide, white aluminum oxide, or tosa and selectively select the particle size of the abrasive powder according to the function 10-70% by weight of the mixed solution of polyvinyl alcohol, depending on the purpose of mixing (31),

이때 연마분이 1차혼합공정(10) 및 1차가열용융공정(20)을 거친 졸 보다 비중이 커서 침전되는 경우가 있으므로 침전을 방지하는 알긴산소오다, CMC(Carboxymethyl ellulose), CMS(Carboxymethyl starch) 중에서 적어도 하나 이상을 선택하여 혼합하는데(32) 총 반응물의 0.5∼10 중량% 정도를 혼합한다.At this time, the abrasive powder may be precipitated because the specific gravity is greater than that of the sol which has undergone the primary mixing process (10) and the primary heating melting process (20). Thus, sodium alginate, CMC (Carboxymethyl ellulose), and CMS (Carboxymethyl starch) At least one of the mixtures is selected and mixed (32), about 0.5 to 10% by weight of the total reactants are mixed.

그러나 연마분의 입자가 120메쉬 이하로 입자의 비중이 커질때에는 침전을 방지하는 안정제로 즉 알긴산소오다, CMC(Carboxymethyl cellulose), CMS(Carboxymethyl starch) 등으로도 침전을 막을 수 없으므로 연마분 혼합과정(31)에서 가열을 함으로서 혼합액의 점도를 증가시키는 공정을 병행할 수 있다.However, when the particle size of the abrasive powder is less than 120 mesh, the particle size of the particles increases, so that the precipitation can not be prevented by the stabilizer to prevent precipitation, ie, sodium alginate, CMC (Carboxymethyl cellulose), or CMS (Carboxymethyl starch). By heating at), a step of increasing the viscosity of the mixed liquid can be performed in parallel.

상기와 같은 공정을 거쳐 만들어진 함수성 연마스폰지는 도 2와 같은 구조를 형성하고 있으며 도 2의 a는 폴리비닐 아세탈 스폰지를 나타내는 것이고, b는 오픈셀(Open cell)(전분 및 덱스트린이 가수분해 되어 빠져 나오며 발생한 용출셀)을 나타내는 것이며, c는 연마제를 나타낸다. 오픈셀(b)의 용출셀의 모세관 현상에 의해 흡수된 물을 폴리비닐 아세탈 스폰지(a)는 저장 역활을 하면서 연마제(c)의 입자가 녹 또는 찌든때가 있는 금속 및 가전제품 등의 표면에 연마하는 기능을 한다. 또 오픈셀(b)의 용출셀은 표면 세척 후에 남은 물기 및 이물질을 흡수 및 흡착하는 기능으로 제거하는 기능도 역시 갖게 된다.The functional abrasive sponge made through the above process forms a structure as shown in FIG. 2, and a in FIG. 2 represents a polyvinyl acetal sponge, and b is an open cell (starch and dextrin hydrolyzed). Elution cell generated while exiting, and c represents an abrasive. The polyvinyl acetal sponge (a) stores the water absorbed by the capillary phenomenon of the elution cell of the open cell (b) on the surface of metals and home appliances, etc., in which the particles of the abrasive (c) are rusted or splashed. Function. In addition, the elution cell of the open cell (b) also has a function of removing and absorbing the water and foreign matter remaining after the surface cleaning.

본 발명에서 사용되는 연마분의 입자 크기는 240메쉬∼120메쉬 또는 120메쉬∼40메쉬 정도 크기의 입자로서 연마 기능에 따른 피물체에 따라 상기 연마분의 입자 크기를 선택하여 혼합하는 것이 바람직하다.The particle size of the abrasive powder used in the present invention is a particle size of about 240 mesh to 120 mesh or about 120 mesh to 40 mesh, and it is preferable to select and mix the particle size of the abrasive powder according to the object according to the polishing function.

상기에 의한 본 발명은 스테인리스, 타일, 유리 및 가전제품 등의 표면에 찌든때 또는 녹을 쉽게 제거할 수 있으며, 종래 피물체의 표면에 연마액을 뿌리고 천 등으로 세척 후 다시 표면을 깨끗하게 닦는 등의 번거로운 작업과정을 본 발명에서는 한번에 처리할 수 있으며 사용 및 취급이 용이하고 폴리비닐 아세탈 스폰지는 내마모성이 강하므로 경제적인 효과를 갖게 된다.The present invention by the above can be easily removed when rust or rust on the surface of stainless steel, tiles, glass and home appliances, such as spraying the polishing liquid on the surface of the conventional object, and then clean the surface again after washing with a cloth or the like In the present invention, a cumbersome work process can be processed at a time, easy to use and handle, and the polyvinyl acetal sponge is economically effective because of its high wear resistance.
