Description

지점토의 제조방법Manufacturing method of clay

본 발명은 일회용 기저귀의 생산시 발생되는 폐기물인 단섬유를 주재료한 지점토의 제조방법을 제공하기위한 것이다.The present invention is to provide a method for producing clay based on short fibers, which is a waste generated in the production of disposable diapers.

일회용 기저귀를 제조함에 있어서는 펄프를 건식초지하되 소정길이 단섬유는 이를 선별 폐기하게 되는데, 본 발명은 이와 같은 일회용 기저귀를 제조하기 위한 공정에서 선별 폐기되는 단섬유를 이용한 이하의 지점토의 제조방법을 제공하기 위한 것이다.In manufacturing disposable diapers, dry paper is pulp but predetermined length short fibers are selectively discarded. The present invention provides the following method for producing clay using the short fibers that are selectively discarded in the process for manufacturing such disposable diapers. It is to.

그런데 일회용 기저귀를 제조하기 위해 단섬유를 선별해내는 과정에서는 필연적으로 초지될 펄프에 혼가한 고흡수성 수지분말이 단섬유와 함께 배출된다. 이와 같이 고흡수성 수지분말이 혼가된 단섬유를 이용해서 물을 넣고 반죽하여 지점토를 제조하게 되면 고흡수성 수지분말이 다량의 수분을 흡수하여 약 1000배 정도의 크기로 팽창하고 팽창된 고흡수성 수지분말은 구성성분들의 접착을 방해하게 된다. 따라서 이와 같이 기저귀 생산시에 발생하는 단섬유는 이를 폐기할 수 밖에 없었고 이러한 폐기물은 그 처리마저 곤란한 지경에 이르렀다.However, in the process of screening short fibers to manufacture disposable diapers, superabsorbent polymer powder confined to the pulp to be made is discharged together with the short fibers. In this way, when the super absorbent polymer powder is mixed with short fibers and mixed with water to prepare clay, the super absorbent polymer powder absorbs a large amount of water and expands to about 1000 times the size of the expanded superabsorbent polymer powder. Silver will interfere with the adhesion of the components. Therefore, the short fibers generated in the diaper production was forced to dispose of these wastes, and these wastes were difficult to process.

이에 본 발명자는 고흡수성 수지분말이 함유된 이러한 단섬유들의 재사용에 대한 연구를 하던중 고흡수성수지분말은 이를 짠 소금물에 넣을 경우 수분을 흡수하지 않음을 알았으며 그 흡수한계는 소금이 석출되기 시작하는 포화수용액의 상태임을 알았다.The inventors of the present invention, while studying the reuse of such short fibers containing superabsorbent resin powder, found that the superabsorbent resin powder does not absorb moisture when it is put in salty salt water, and the absorption limit starts to precipitate salt. It was found that the state of saturated aqueous solution.

지점토 공예에 사용될 물은 비록 그것이 심하게 짠 물이라 하더라도 지점토의 반죽에 아무런 지장을 초래하지 않음은 물론이다. 그리하여 본 발명자는 일회용 기저귀를 생산할 때 발생되는 폐기물인 단섬유를 소재로 한 지점토의 제조방법을 발명하기에 이르렀던바 이와 같은 본 발명을 실시예에 의하여 설명하면 다음과같다.The water used for the clay craft, of course, does not interfere with the clay dough, even if it is very salty. Thus, the inventors have come to invent a method for producing clay clay using short fibers, which is a waste generated when producing disposable diapers. The present invention will be described with reference to Examples.

[실시예]EXAMPLE

일회용 기저귀의 생산시 발생된 단섬유 80부량(중량비 : 이하같음)에 수성 E.V.A.분말과 C.M.A.분말 및 콘스타치를 5 : 4 : 1로 혼합한 바인더(binder) 10부량 및 활석분말 10부량을 혼가하여 지점토를 마련한후 이에 180부량의 소금물을 가하여 반죽하므로서 소기의 지점토를 얻었다. 반죽에 사용하는 소금물은 통속에 소금을 넣고 물을 부은 후 충분히 교반하되 통의 바닥에 소금이 남아있을 정도로 소금을 많이 넣어서 된소금의 포화수용액을 사용하였다.The clay was mixed with 80 parts by weight of short fibers produced in the production of disposable diapers (10 parts by weight) and 10 parts by weight of binder and 10 parts by weight of talc powder mixed with aqueous EVA powder, CMA powder and corn starch in a 5: 4: 1 ratio. After preparing the kneading by adding 180 parts of salt water to the desired clay was obtained. The salt water used for the dough was put in a bucket of salt, poured with water, and stirred well, but a large amount of salt was added to the salt so that salt remained at the bottom of the barrel.

위와 같은 실시예에서 바인더를 사용하는 것은 섬유에 점성이 없기 때문이며 따라서 이와 같은 바인더는 반드시 위와 같은 조성물일 필요는 없다. 또한 활석분말을 가하는 것은 그 표면을 매끄럽게 하기 위한 충전제로 사용하는 것이니 그 첨가량 또한 반드시 위와 같은 양이어야 하는 것도 아니다. 바인더로서 석회나 곡물가루등을 사용할 경우 이들은 충전제로서의 작용도 가질 수 있다. 요컨대 위의 실시예에 있어서 바인더나 충전제를 사용하는 기술은 펄프를 이용한 종이등의 각종 제품에 널리 알려진 공지의 기술이며 단지 본 발명은 그 주재인 단섬유에 고흡수성 수지가 혼합되어 있음에도 불구하고 물 반죽시 이러한 고흡수성 수지가 물을 흡수하지 아니하도록 함에 있다. 그리고 이러한 지점토 반죽에 사용하는 물은 소금물만이 아니라 염화암모늄 수용액과 같은 포화염소화합물 수용액이 두루 사용될 수 있음을 알았다.The use of a binder in such an embodiment is because the fibers are not viscous and therefore such a binder does not necessarily have to be such a composition. In addition, talc powder is used as a filler for smoothing the surface thereof, and the amount of addition thereof is not necessarily the same. If lime or grain flour is used as the binder, they may also act as fillers. In other words, in the above embodiment, the technique of using a binder or filler is a well-known technique widely known in various products such as paper using pulp. When kneading, such superabsorbent resin does not absorb water. And it was found that the water used for the clay dough may be used not only in brine but also in saturated aqueous chlorine compounds such as ammonium chloride solution.

이와 같은 본 발명은 일회용 기저귀의 제조시에 다량 발생되는 산업 폐기물인 단섬유를 학습용 교재인 지점토로 재활용할 수 있게하며, 미세한 모형 조성이 가능하고 무게가 가벼우며 착색이 용이하고 가격이 저렴한 지점토를 제공할 수 있는 효과가 있다.The present invention enables the recycling of short fibers, which are industrial waste generated in the manufacture of disposable diapers, into clay, which is a teaching material, and fine model composition, which is light in weight, easy to color, and inexpensive. There is an effect that can be provided.
