공작용 인공점토 조성물Synthetic Artificial Clay Composition
본 발명은 공작용 인공점토에 관한 것으로, 보다 상세하게는 장시간 사용시 굳지 아니하고, 끈적거림이 없으며, 장시간 원형 유지가 가능하고, 환경위생학적으로 안전한 인공점토 조성물로서, 특히 물에 뜰 수 있는 공작용 인조점토 조성물에 관한 것이다.The present invention relates to a synthetic artificial clay, and more particularly, it does not harden when used for a long time, there is no stickiness, and it is possible to maintain a circular shape for a long time, and is an environmental hygienically safe artificial clay composition, in particular, which can float on water It relates to an artificial clay composition.
공작용 점토는 유연성이 있어 손으로 원하는 모양으로 쉽게 변형이 가능하고, 건조시키면 경화되어 제작물이 장시간 그 형상이 유지된다. 초기의 공작용 점토는 무기계 물질과 물로 구성되어 있어 점토 자체가 무거우며, 또한 수분이 빨리 없어져 빠른 시간 내에 원하는 조형물을 만들어야 하고, 재사용이 불가능하며, 조형물의 표면이 갈라지는 현상 등이 있었다. 이러한 문제점들을 해결하기 위해, 수용성 고분자와 여러 가지 첨가제들을 사용하여 인공점토를 만들어 사용하고 있다. 한편, 디부틸프탈레이트와 같은 프탈레이트계의 내부 가소 물질 등이 사용되는 경우 위생적이고 환경친화적인 제품으로 볼 수는 없다. 어린이들이 사용하는 공작용 점토이기 때문에 환경위생학적으로 보다 안전한 인공 점토가 요구되고 있다.The working clay is flexible and can be easily transformed into the desired shape by hand, and when it is dried, it is cured and the product is maintained for a long time. Initially, the working clay was composed of inorganic materials and water, and the clay itself was heavy, and moisture was quickly removed to make a desired sculpture quickly, and it was impossible to reuse it, and the surface of the sculpture was cracked. In order to solve these problems, artificial clay is used by using a water-soluble polymer and various additives. On the other hand, when a phthalate-based internal plastic material such as dibutyl phthalate is used, it cannot be regarded as a hygienic and environmentally friendly product. Since it is a working clay used by children, environmentally safe artificial clays are required.

In addition, children often play with sculptures in water. If artificial clay has a floating property, it is expected to reduce the risk of loss in water, and to expand the range of utilization of the working clay.

본 발명에서의 실리콘검은 다양한 유기그룹을 갖는 폴리다이오르가노실록산의 단독 내지는 공중합체의 형태일 수 있으며, 구체적인 예로서, 분자량 500,000 내지 1,000,000인 폴리디메틸실록산화합물로서 말단이 메틸기, 수산기 및 비닐기로 이루어진 군으로부터 선택된 것을 사용하는 것이 바람직하며, 특히 비닐기의 말단을 갖는 화합물이 바람직하다. 물론, 가소도의 조절 등을 위해 열가소성 엘라스토머를 사용하지만 실리콘검의 분자량이 너무 작으면 모형물 제작후 쉽게 무너지는 단점인 처짐현상(sagging)이 일어나기 쉽고, 분자량이 너무 커지면 인공점토 조성물의 내부 응력의 증대로 형태변형이 자유롭지 못한 단점이 발생하게 된다.Silicone gum in the present invention may be in the form of a single or copolymer of polydiorganosiloxane having a variety of organic groups, as a specific example, a polydimethylsiloxane compound having a molecular weight of 500,000 to 1,000,000 end of the methyl group, hydroxyl group and vinyl group Preference is given to using those selected from the group, in particular compounds having a terminal of a vinyl group. Of course, the thermoplastic elastomer is used to control the plasticity, but if the molecular weight of the silicone gum is too small, sagging, which is a disadvantage that easily collapses after the model is easily produced, is too large. As a result, the disadvantage that the shape deformation is not free.
열가소성 엘라스토머는 가소특성은 물론 고무특성(탄성특성)을 모두 갖는 중합체성 물질이다. 열가소성 엘라스토머는 통상의 열경화성 고무와는 상이한 탄성 기계적 특성을 가지며, 승온에서 재가공될 수 있다. 제작된 물품의 재생이 가능하여 스크랩이 현저하게 감소되기 때문에, 열가소성 엘라스토머의 재가공성은 화학적으로 가교결합된 실리콘고무 형태보다 상당히 유리하다. 일반적으로 열가소성 엘라스토머는 융점 또는 유리전이온도가 주위 온도보다 높은 경질 가소성 부분과 주위 온도보다 낮은 연질 중합성 부분을 함유하고 있고, 경질 부분은 응집되어 별개의 미세상을 형성하고 연질 부분에 대한 물리적 가교결합제로 작용하여 실온에서 열가소성 엘라스토머에 탄성특성을 부여하게 되고, 승온과정에서 경질 부분이 용융되거나 연화되어 열가소성 수지처럼 가공될 수 있게 된다. 이러한 특성은 본 발명의 인공점토가 가혹한 외부환경 내지는 보관시에도 탄성유지와 형태변형이 적은 점을 더욱 강화시키고 있다. 본 발명에서는 열가소성 엘라스토머로 폴리올레핀 고무, 부타디엔 고무, 에틸렌-옥텐 공중합체 및 에틸렌-프로필렌 고무로 이루어진 군으로부터 선택된 것이 바람직하고, 상기 열가소성 엘라스토머의 분자량은 1,000 내지 500,000인 것이 바람직하다. 본 발명의 열가소성 엘라스토머는 가소성과 탄력성을 증대시켜, 실리콘검의 단점인 처짐현상을 방지하여 장기간 방치시 모형물의 원형유지를 가능하게 한다.Thermoplastic elastomers are polymeric materials having both plasticity and rubber properties (elastic properties). Thermoplastic elastomers have different elastic mechanical properties than conventional thermoset rubbers and can be reworked at elevated temperatures. Since recyclability of the manufactured articles is possible and scrap is significantly reduced, the reworkability of thermoplastic elastomers is considerably advantageous over chemically crosslinked silicone rubber forms. Generally, thermoplastic elastomers contain hard plastic parts having a melting point or glass transition temperature higher than the ambient temperature and soft polymerizable parts lower than the ambient temperature, and the hard parts aggregate to form separate microphases and physical crosslinks to the soft part. It acts as a binder to impart elastic properties to the thermoplastic elastomer at room temperature, and the hard part may be melted or softened in the process of heating to be processed like a thermoplastic resin. This characteristic further enhances the point that the artificial clay of the present invention has little elasticity and shape deformation even in a harsh external environment or storage. In the present invention, the thermoplastic elastomer is preferably selected from the group consisting of polyolefin rubber, butadiene rubber, ethylene-octene copolymer, and ethylene-propylene rubber, and the molecular weight of the thermoplastic elastomer is preferably 1,000 to 500,000. The thermoplastic elastomer of the present invention increases plasticity and elasticity, and prevents sagging, which is a disadvantage of silicon gum, to maintain the prototype of the model when left for a long time.
아울러, 본 발명의 열가소성 엘라스토머는 공작용 인공점토의 전체적인 비중을 낮추는 역할도 한다. 폴리올레핀 고무는 밀도가 0.83 내지 0.85 정도로 가장 가벼운 플라스틱에 속하고 그 투명성도 우수하다. 부타디엔 고무는 밀도가 0.91 내지 0.92 정도이며, 천연고무보다 탄력성이 좋고 내마모성이 우수하며, 에틸렌-옥텐 공중합체는 옥텐의 함량에 따라 0.86 내지 0.91 정도의 밀도를 가진다. 에틸렌-프로필렌 고무도 0.86 내지 0.87 정도이기 때문에 본 발명에서 인공점토의 전체적인 비중을 낮추는데 어느 정도의 역할을 할 수 있다.In addition, the thermoplastic elastomer of the present invention also serves to lower the overall specific gravity of the working artificial clay. Polyolefin rubber belongs to the lightest plastic with a density of 0.83 to 0.85 and also has excellent transparency. Butadiene rubber has a density of about 0.91 to 0.92, more elasticity and better wear resistance than natural rubber, and the ethylene-octene copolymer has a density of about 0.86 to 0.91 depending on the content of octene. Since ethylene-propylene rubber is also about 0.86 to 0.87 in the present invention may play a role in lowering the overall specific gravity of the artificial clay.
본 발명에서는 내부윤활제를 사용하여 장시간 사용에도 굳는 것을 방지할 수 있도록 한다. 윤활제로는 합성유, 동식물유, 광물유 등이 사용될 수 있으며, 특히 불포화기가 없고 변색이 적은 폴리디메틸실록산화합물이 바람직하다. 폴리디메틸실록산계의 실리콘유는 넓은 온도범위에서 점성률의 변화가 적고, 내열성, 내한성, 발수성이 뛰어나며, 인체에 무해하다. 좀더 구체적으로, 점도가 0.65 내지 10,000 CTS이고 분자량이 500 내지 100,000 정도인 것이 적당하다. 통상 실리콘유는 비휘발성이나, 분자량이 너무 적으면 휘발성이 강해 인공점토를 굳지 않게 하는 역할을 잘 달성할 수 없고, 분자량이 크면 본래의 목적인 윤활효과가 떨어지고 배합 및 혼합시 균일한 조성물을 얻기 어렵게 되고, 분자량이 커지면 점성도가 커지면서 비중도 늘어나게 된다.In the present invention, it is possible to prevent the use of the internal lubricant to harden even for a long time use. Synthetic oils, animal and vegetable oils, mineral oils and the like may be used as the lubricant, and polydimethylsiloxane compounds having no unsaturated group and little discoloration are preferable. Polydimethylsiloxane-based silicone oil has a small change in viscosity rate over a wide temperature range, and is excellent in heat resistance, cold resistance, and water repellency, and is harmless to the human body. More specifically, it is suitable that the viscosity is 0.65 to 10,000 CTS and the molecular weight is about 500 to 100,000. Generally, silicone oil is non-volatile, but if the molecular weight is too small, the volatility is strong so that it cannot achieve the role of hardening artificial clay, and if the molecular weight is large, the original lubricating effect is inferior, and it is difficult to obtain a uniform composition during compounding and mixing. As the molecular weight increases, the specific gravity increases as the viscosity increases.
상기한 실리콘검, 열가소성 엘라스토머, 윤활제가 배합 및 혼합되어 기본적인 실리콘 인공점토를 구성하고, 여기에 더하여 내부 충진제, 다공성 미분말, 및 필요에 따라 착색제, 항균제 등을 부가하여 실리콘 인공점토의 특성을 부가하게 된다.The above-mentioned silicone gum, thermoplastic elastomer, and lubricant are blended and mixed to form basic silicone artificial clay, and additionally, internal filler, porous fine powder, and colorant, antimicrobial agent, etc. are added as necessary to add characteristics of silicone artificial clay. do.
내부 충진제는 분말 형태로 첨가되는데, 인공점토의 끈적임을 줄여주는 역할을 함과 동시에 실리콘재료의 함량을 대체하는 역할을 하여 공작용 인공점토의 가격 경쟁력을 높이는 역할을 한다. 상기 내부 충진제는 폴리메틸메타크릴레이트, 폴리아크릴로니트릴, 구상 실리콘, 플라스틱 가루 및 목재 가루로 이루어진 군으로부터 선택된 분말상의 유기충진제이거나, 실리카, 탈크, 탄산칼슘, 마이카, 수산화알루미늄, 산화알루미늄 및 황산바륨으로 이루어진 군으로부터 선택된 분말상의 무기충진제인 것이 바람직하다. 분산성을 향상시키기 위해 컴파운딩 과정에서 표면처리제에 의해 표면처리함으로써 균일한 분산을 꾀할 수도 있다. 본 발명의 공작용 인공점토가 물에 뜰 수 있도록 하기 위해 다공성 미분말을 또한 첨가하는데, 상기 내부 충진제로 사용할 수 있는 물질 중에도 다공성 물질의 성격을 갖거나, 비중이 상당히 낮은 것들이 많아 공작용 인공점토의 전체적인 비중을 낮추는 역할도 함께 한다. 한편, 중공성 폴리아크릴로니트릴 분말은 폴리아크릴로니트릴 표면을 탄산칼슘, 탈크 등의 무기분체로 코팅하여 사용할 수 있다. 내부 충진제는 실리콘검 100중량부를 기준으로 5 내지 40 중량부를 사용하는 것이 바람직하다. 사용되는 양이 너무 적을 경우, 내부 충진제의 본래의 목적에 부합하지 않고, 너무 많은 경우, 실리콘 소재의 인공점토의 물성이 좋지 않게 될 수 있다. 내부 충진제의 입자의 크기는 10 nm 내지는 1,000 ㎛의 것이 적당하며, 입자가 너무 작으면 분산이 어려울 뿐만 아니라 비교적 고가이므로 적당하지 않고, 입자가 너무 크면 공작용 인공점토의 유동성 조절이 어려운 점이 있다.The internal filler is added in the form of powder, which serves to reduce the stickiness of artificial clay and at the same time, to replace the content of silicone material, thereby increasing the price competitiveness of the artificial artificial clay. The internal filler is a powdered organic filler selected from the group consisting of polymethyl methacrylate, polyacrylonitrile, spherical silicon, plastic powder and wood powder, or silica, talc, calcium carbonate, mica, aluminum hydroxide, aluminum oxide and sulfuric acid. It is preferably a powdery inorganic filler selected from the group consisting of barium. In order to improve dispersibility, it is possible to achieve uniform dispersion by surface treatment with a surface treatment agent in the compounding process. In order to allow the artificial clay of the present invention to float on water, a porous fine powder is also added. Among the materials that can be used as the internal filler, many of the materials that can be used as internal fillers have a characteristic of a porous material or have a relatively low specific gravity. It also plays a role in reducing the overall weight. On the other hand, the hollow polyacrylonitrile powder may be used by coating the polyacrylonitrile surface with an inorganic powder such as calcium carbonate or talc. The internal filler is preferably used 5 to 40 parts by weight based on 100 parts by weight of silicone gum. If the amount used is too small, it does not meet the original purpose of the internal filler, if too large, the physical properties of the artificial clay of the silicone material may be poor. The size of the particles of the internal filler is 10 nm to 1,000 ㎛ is suitable, too small particles are difficult to disperse as well as relatively expensive, and if the particles are too large it is difficult to control the fluidity of the artificial artificial clay.
내부 충진제가 인공점토의 끈적임을 줄여주는 역할을 함과 동시에 실리콘 재료의 함량을 대체하는 역할을 하여 공작용 인공점토의 가격 경쟁력을 높이는 역할을 하는 측면이 있는 반면에, 가늘고 긴 형상의 모형물을 만들 때 조형성이 떨어지는 문제를 유발할 수도 있지만, 본 발명에서는 실리콘검에 가소성 엘라스토머를 사용하기 때문에 신장성도 충분히 발휘될 수 있도록 도와 이러한 내부 충진제의 사용으로 인한 부작용을 막을 수 있다. 즉, 실리콘검과 가소성 엘라스토머 및 상기 내부 충진제의 조합은 특유의 과제해결원리에 기초하여 유기적으로 결합된 실시형태인 것이다.While internal fillers reduce the stickiness of artificial clays and at the same time replace the content of silicone materials, they also increase the price competitiveness of synthetic artificial clays, while creating thin and long models. Although it may cause a problem of poor molding, in the present invention, since the plastic elastomer is used in the silicone gum, the extensibility may be sufficiently exerted to prevent side effects due to the use of such internal fillers. That is, the combination of the silicone gum, the plastic elastomer and the internal filler is an embodiment that is organically bonded based on the unique problem solving principle.
본 발명에서는 다공성 또는 중공성 미분말을 또한 첨가하여 사용한다. 본 발명에서는 열가소성 엘라스토머, 비중이 낮은 내부 충진제 등을 사용하여 전체적인 비중을 낮추고 있으며, 추가적으로 다공성 미분말등을 첨가하여 물에 뜰 수 있는 인공점토를 제공할 수 있다. 즉, 본 발명에서는 인공점토가 물에 뜰 수 있는 조성이 유기적으로 결합된 것이다. 구체적인 예로서 실리카졸로부터 합성한 다공성 실리카나, 중공성 폴리메틸메타크릴레이트, 중공성 우레탄아크릴레이트가 바람직하다. 다공성 또는 중공성 미분말은 실리콘검 100 중량부를 기준으로 5 내지 40 중량부를 사용하는 것이 바람직하다.In the present invention, porous or hollow fine powder is also added and used. In the present invention, the overall specific gravity is reduced by using a thermoplastic elastomer, a low specific gravity internal filler, and the like, and an artificial clay that can float on water may be added by adding porous fine powder. In other words, in the present invention, the artificial clay is organically bonded to float in water. As a specific example, porous silica synthesized from silica sol, hollow polymethyl methacrylate, and hollow urethane acrylate are preferable. The porous or hollow fine powder is preferably used 5 to 40 parts by weight based on 100 parts by weight of silicon gum.
본 발명의 공작용 인공점토에 다양한 색상을 연출하기 위하여 착색제를 사용할 수 있다. 착색제는 요구되는 조건에 따라 다양한 것들을 사용할 수 있으며, 바람직하게는 용출 염려가 적은 무기 안료가 적합하다. 백색 착색제로는 산화티탄, 실버화이트 등이 있으며 적색 착색제로는 벵갈라, 산화철 등이 있고, 청색 착색제로는 프러시안블루, 코발트 청 등이 있으며, 검정색 착색제로는 카본블랙 등이 있다. 착색제는 실리콘검 100 중량부에 대하여 0.1 내지 5 중량부를 포함할 수 있으며, 착색제의 종류와 필요에 따라 적절한 함량으로 조절할 수 있다. 착색제의 함량이 너무 적으면 착색효과가 떨어질 수 있으며, 너무 많은 경우 색상이 어두워지고 가격이 높아질 뿐만 아니라 착색제가 묻어 나올 수 있다. 염료의 형태로는 아조염료, 안트라퀸논염료, 벤조다이프라논염료, 다환 방향족카보닐 염료, 니트로조화합물염료 등이 있다.Colorants can be used to produce a variety of colors in the synthetic artificial clay of the present invention. The colorant can be variously used depending on the required conditions, and preferably, inorganic pigments having low dissolution concern are suitable. The white colorant includes titanium oxide and silver white, and the red colorant includes bengal and iron oxide. The blue colorant includes Prussian blue and cobalt blue, and the black colorant includes carbon black. The colorant may include 0.1 to 5 parts by weight based on 100 parts by weight of the silicone gum, and may be adjusted to an appropriate content according to the type and need of the colorant. Too little content of the colorant may impair the coloring effect, too much color darkens and becomes expensive, as well as colorant. Examples of the dyes include azo dyes, anthraquinone dyes, benzodipranon dyes, polycyclic aromatic carbonyl dyes, and nitrozo compound dyes.
본 발명의 공작용 인공점토에는 세균감염 및 곰팡이 발생을 억제하기 위한 항균제를 사용할 수 있다. 항균제는 실리콘검 100 중량부에 대하여 0.1 내지 5 중량부를 포함할 수 있으며, 항균제의 종류와 필요에 따라 적절한 함량으로 조절할 수 있다. 항균제가 너무 적은 경우 항균효과가 떨어지고, 너무 많은 경우에는 가격이 상승하고 용출우려가 있게 된다. 유기항균제보다는 무기항균제가 그 효과를 지속시킬 수 있어 보다 바람직하며, 금속산화물 형태의 항균제, 나노실버, 제올라이트 등이 포함된다. 유기 항균제로는 이미다졸계, 카벤다짐게, 니트로퓨라존계 등이 있으며, 다만 용출의 문제점, 내열성, 항균지속력이 짧은 문제점이 있다.In the artificial clay of the present invention, an antibacterial agent for inhibiting bacterial infection and mold development can be used. The antimicrobial agent may include 0.1 to 5 parts by weight based on 100 parts by weight of the silicone gum, and may be adjusted to an appropriate amount according to the type and need of the antimicrobial agent. Too little antimicrobial will reduce the antimicrobial effect, too much will increase the price and dissolution concerns. Inorganic antimicrobial agents are more preferable than organic antimicrobial agents because they can sustain the effect, and include antimicrobial agents in the form of metal oxides, nanosilver, zeolite and the like. Organic antimicrobial agents include imidazole-based, carbendazim crab, nitrofurazone-based, etc., but there are problems of elution, heat resistance, and short-term antimicrobial durability.
