일반적으로 공지된 공작용 고무찰흙(일명 고무점토)은 어린이들이 손쉽게 공작놀이를 할 수 있도록 제작된 것으로; 유성 고무찰흙 또는 수성 고무찰흙 등으로 제조/판매되고 있다. 유성 고무찰흙은 조형물을 제작한 후 보관시 모형 그대로 형태를 유지할 수 있으나, 고무찰흙이 단단하여 어린이들이 이를 재료로 모형을 제작하기가 어려운 단점이 있다. 그리고 수성 고무찰흙은 반죽이 용이하여 어린이들이 놀이 용도로 사용하기가 편한 반면에, 수분의 함량의 많아 제작시 끈적임 현상이 심하고 건조되었을 때 수축 및 뒤틀림 현상이 발생하여 장기간 보관이 어려운 단점이 있다. 또한, 상기의 유성 고무찰흙과 수성 고무찰흙은 공작물을 제작한 후 방치하면 쉽게 굳어 재사용이 불가능한 단점이 있다.In general, the known rubber clay (aka rubber clay) is made so that children can easily play peacock; It is manufactured / sold in oily rubber clay or water-based rubber clay. Oily clay can maintain its shape as it is stored after it is produced, but it has a disadvantage that it is difficult for children to make a model from the material. And the water-based rubber clay is easy to use for children to play because the dough is easy, while a lot of moisture content of the sticky phenomenon in the manufacturing and shrinkage and distortion occurs when dried, it is difficult to store for a long time. In addition, the above-mentioned oil-based rubber clay and water-based rubber clay has a disadvantage that it is hard to be easily reused if left after manufacturing the workpiece.
이러한 단점을 해결하기 위해 본 출원인은 무기화합물을 주성분으로 가소도를 적정하게 제작하여 끈적임이 없어 손에 달라붙지 않으며 공작물(모형)을 만들어 장시간 방치하여도 굳지 않아 재사용이 가능하며 다양한 색상을 연출할 수 있는 "공작용 고무찰흙"을 2010년 06월 08일자로 대한민국 특허청에 출원(출원번호 10-2010-0053756호)하였고, 2011년 01월 26일자로 등록(등록번호 제10-1012314)되어 그 권리를 확보하고 있다.In order to solve these shortcomings, the Applicant can make plasticity with inorganic compounds as the main ingredient, so that it does not stick to hands because it is not sticky and does not stick to hands for a long time by creating a workpiece (model). Filed with the Korean Patent Office on June 08, 2010 (Application No. 10-2010-0053756), and registered on January 26, 2011 (Registration No. 10-1012314). To secure.
대한민국 등록특허 제10-1012314호에 개시된 "공작용 고무찰흙"은 전체 고무찰흙 중량에 대하여 60 ~ 80%로 마련되며 실로산과 실리콘,다이메틸, 메틸비닐, 비닐군-터미네이티드가 혼합되어 이루어진 젤상태의 실리콘베이스와; 전체 고무찰흙 중량에 대하여 15 ~ 35%로 마련되며 파우더 형태의 실리카계로 이루어져 경도 조절을 위한 가소도 조절제와; 전체 고무찰흙 중량에 대하여 1 ~ 5%로 마련되며 폴리다이메틸실록산계로 이루어져 고화를 방지하기 위한 오일 형태의 고화방지제와; 전체 고무찰흙 중량에 대하여 0.1 ~ 1%로 마련되며 세균번식을 방지하기 위한 항균제를; 혼합하여 이루어진 것을 기술적 특징으로 하고 있다. 상기와 같은 조성물로 이루어진 공작용 고무찰흙에서는 투명도가 우수한 무기화합물이 주성분이면서 오일형태의 고화방지제가 혼합되어 있기 때문에, 끈적임이 없어 손에 달라붙지 않으며 공작물(모형)을 만들어 장시간 방치하여도 굳지 않아 재사용이 가능한 장점이 있다. 또한, 무기화합물 주성분에 항균제가 추가되어 있어서 고무찰흙을 반복적으로 사용하여도 세균번식을 방지할 수 있다."Synthetic rubber clay" disclosed in Republic of Korea Patent No. 10-1012314 is provided with 60 to 80% by weight of the total rubber clay and made of a mixture of siloic acid and silicon, dimethyl, methyl vinyl, vinyl group-terminated A gel silicone base; It is provided with 15 to 35% by weight of the total rubber clay and made of a powder-based silica-based plasticity regulator for hardness control; It is provided with 1 to 5% by weight of the total rubber clay and made of polydimethylsiloxane system to prevent solidification in the form of an oil to prevent solidification; It is provided with 0.1 to 1% by weight of the total rubber clay and antibacterial agent to prevent bacterial growth; It is a technical feature made by mixing. In the functional rubber clay composed of the composition as described above, since the inorganic compound having excellent transparency is mixed with the main component and the anti-solidification agent in the form of oil, it is not sticky and does not stick to the hand, and it does not harden even after standing for a long time by making a workpiece (model) It has the advantage of being reusable. In addition, since the antimicrobial agent is added to the main ingredient of the inorganic compound, it is possible to prevent bacterial growth even if the rubber clay is repeatedly used.
그러나 상기의 특허 제10-1012314호에 개시된 "공작용 고무찰흙"에서는 추가되는 색상안료를 달리하여 다양한 칼라를 연출할 수는 있지만, 자체적으로는 색상을 달라지게 할 수 없다. 이에 따라 공작용 고무찰흙을 가지고 놀이는 하는 대부분의 유아나 어린이들에게 호기심과 창의/창작성을 유발시키는데 그 한계가 있다.However, in the "working rubber clay" disclosed in the above Patent No. 10-1012314, it is possible to produce a variety of colors by changing the color pigments added, but can not change the color itself. As a result, most infants and children who play with the action rubber clay have limitations to induce curiosity and creativity / creation.

위의 [표 1]에 나타낸 것처럼 실시예 1을 통해 제조된 공작용 고무찰흙은 상온에서 오랜시간 방치하여도 전혀 굳지 않았으며, 가소도가 적정하여 제품으로 공작물을 성형하여도 제품 모형이 잘 일그러지지 않아 공작물의 성형을 용이하여 장기간 보관이 가능하였다.As shown in the above [Table 1], the functional rubber clay prepared in Example 1 did not harden at all even after being left at room temperature for a long time, and the product model was well shaped even when the workpiece was molded into a product with proper plasticity. It is not easy to form the workpiece, so it can be stored for a long time.
그러나 비교예 1을 통해 제조된 공작용 고무찰흙은 상온에서 오랜 시간 방치되도 전혀 굳지 않았으며, 가소도가 너무 낮아 공작물을 성형해도 공작물의 모형이 일그러지며, 비교예 2를 통해 제조된 공작용 고무찰흙은 제품이 만들어지지 않고 부서지기 때문에 공작물의 제조가 불가능하였다.However, the functional rubber clay prepared in Comparative Example 1 was not hardened at all even after being left at room temperature for a long time, and the plasticity was so low that even when the workpiece was molded, the model of the workpiece was distorted, and the functional rubber prepared through Comparative Example 2 Clay was unable to manufacture a workpiece because the product was broken, not made.
상기 실시예 1을 통해 제조된 공작용 고무찰흙과 타사제품의 가소도 경시변화(단위:Units)를 측정하여 아래 [표 2]에 나타내었다.The plasticity over time changes (units) of the functional rubber clay and the other company's products manufactured through Example 1 were measured and shown in the following [Table 2].

위의 [표 2]에서 알 수 있듯이, 본 발명에 따른 공작용 고무찰흙의 경우 측정에 약간의 오차는 있겠지만, 오랜 시간 상온에 방치하여도 가소도의 큰 변화가 없어 언제든지 공작이 가능한 반면에, A사 제품의 경우는 시간이 지날수록 가소도가 향상되어 1일 이상 경과하면 표면에 균열이 발생하여 공작이 불가능하며, B사 제품의 경우는 시간이 경과함에 따라 가소도가 증가하여, 1일 이상이 경과하면 표면이 스펀지처럼 굳어 공작이 불가능하고, C사 제품의 경우는 처음부터 가소도가 높아 유아나 어린이가 공작물을 만들기에는 매우 부적합하였다.As can be seen in the above [Table 2], in the case of the working rubber clay according to the present invention there will be some errors in the measurement, even if left at room temperature for a long time there is no large change in the degree of plasticity, while work is possible, In case of company A, plasticity improves as time goes by. If more than 1 day elapses, the surface is cracked and work is impossible.In case of company B, plasticity increases as time passes. If the above elapses, the surface is hardened like a sponge, so it is impossible to work. In the case of C company, the plasticity is high from the beginning, and it is very unsuitable for infants and children to make a workpiece.
한편, 본 발명에 따른 공작용 고무찰흙에 필수적으로 혼합되는 색상안료와 시온안료의 함량비 조절을 통해 온도변화에 따라 자체 색상이 변화되는 고무찰흙 반죽을 만들 수 있다. 예를 들면, 노란색의 색상안료가 혼합된 본 발명에 따른 공작용 고무찰흙이 상온(18℃)에서는 진한 노란색을 띠다가 40℃에서는 시온안료 칼라가 투명으로 되어 전체적으로는 흰색에 가까운 엷은 노란색으로 변하며, 주황색의 색상안료가 혼합된 본 발명에 따른 공작용 고무찰흙이 상온(18℃)에서는 진한 주황색을 띠다가 40℃에서는 엷은 주황색으로 변하며, 보라색의 색상안료가 혼합된 본 발명에 따른 공작용 고무찰흙이 상온(18℃)에서는 진한 보라색을 띠다가 40℃에서는 엷은 하늘색으로 변하게 된다. 이에 따라 본 발명에 따른 공작용 고무찰흙을 가지고 공작물을 만들게 되면, 온도에 따라 공작물의 색상이 다양하게 변해 어린이나 유아들에게 호기심과 창의/창작성을 보다 효과적으로 유발시킬 수 있다.On the other hand, by adjusting the content ratio of the color pigments and Zion pigments are essentially mixed in the functional rubber clay according to the present invention can make a rubber clay dough that changes its own color according to temperature changes. For example, the functional rubber clay according to the present invention in which yellow pigments are mixed is dark yellow at room temperature (18 ° C.), and at 40 ° C., the zion pigment color becomes transparent and becomes pale yellow as a whole. , The rubbery rubber clay according to the present invention mixed with orange pigments is dark orange at room temperature (18 ° C) and turns to pale orange at 40 ° C, and the rubbery rubber compound according to the present invention is mixed with purple color pigments. Clay is dark purple at room temperature (18 ℃), but turns to pale sky blue at 40 ℃. Accordingly, when the workpiece is made with the working rubber clay according to the present invention, the color of the workpiece is changed in accordance with the temperature, thereby inducing curiosity and creativity / creation more effectively for children or toddlers.
또한, 상기와 같은 본 발명의 따른 공작용 고무찰흙에서 앞서 기술한 바와 같이, 필수조성물 이외에 부가적으로 항균제와 축광제가 혼합되어 세균번식을 억제할 수 있으며 야광기능을 부여할 수 있음은 물론이다.In addition, as described above in the functional rubber clay according to the present invention as described above, in addition to the essential composition, the antimicrobial agent and the photoluminescent agent may be additionally mixed to suppress bacterial growth and may impart a luminous function.
본 발명은 실리콘베이스를 주재료로 하여 끈적임이 없으며 공작물을 만든 후 장시간 방치하여도 딱딱하게 굳지 않아 재사용이 가능한 공작용 고무찰흙 분야에 광범위하게 이용될 수 있다.The present invention has a silicone base as a main material is non-sticky and can be widely used in the field of the functional rubber clay that can be reused because it does not harden even after leaving for a long time after making the workpiece.
