Description
본 발명은 공예용 조성물에 관한 것으로써, 보다 상세하게는 반응성 미네랄을 포함하는 주제와 수성 아크릴 레진을 포함하는 경화제가 혼합되어 경화 속도, 경도 등이 향상된 공예용 조성물에 관한 것이다.The present invention relates to a craft composition, and more specifically, to a craft composition having improved curing speed, hardness, etc., by mixing a subject matter including a reactive mineral and a hardener including a water-based acrylic resin.
레진아트, 레진공예는 레진(Resin)으로 액세서리나 인테리어 소품 등을 만드는 걸 일컫는 말이다.Resin art and resin crafts refer to making accessories and interior items using resin.
현재, 공예용 레진은 경화 방법에 따라 자연경화 레진과 광경화성 레진으로 구분된다.Currently, craft resins are divided into natural curing resins and photocuring resins depending on the curing method.
자연경화 레진은 주제(resin)와 경화제(hardner)를 일정한 비율로 혼합해 일어나는 화학반응으로 경화시키는 2액형 레진으로, 대표적으로 에폭시 레진이 사용되고 있다. Natural curing resin is a two-component resin that hardens through a chemical reaction by mixing a resin and a hardener in a certain ratio. Epoxy resin is a representative example.
에폭시 레진은 저가이고 다른 재료들과 혼화가 가능한 장점이 있으나, 황변 현상(Yellowing)이 일어나고 경화시간이 오래 걸리며 기포가 발생하기 쉬워 외관이 손상될 수 있고, 경화하기 전의 액체나 기화시 발생하는 가스는 인체에 유해한 단점이 있다.Epoxy resin has the advantages of being inexpensive and compatible with other materials, but it has the disadvantages of being prone to yellowing, taking a long time to cure, easily generating bubbles, which can damage the appearance, and the liquid before curing or the gas generated when vaporizing can be harmful to the human body.
광경화성 레진은 UV램프를 이용해 경화하는 1액형 타입의 수지로서, UV레진을 의미하며 램프를 이용하기 때문에 2액형 레진에 비해 경화 속도가 빠른 장점이 있으나, 가격이 비싸고 램프의 크기에 한계가 있어 크기가 큰 작품은 만들기 어려운 단점이 있다.Photocurable resin is a one-component type resin that hardens using a UV lamp. It refers to UV resin and has the advantage of a faster curing speed than two-component resin because it uses a lamp. However, it has the disadvantage of being expensive and having limitations on the size of the lamp, making it difficult to produce large-sized works.
따라서, 종래 레진들이 갖는 황변 현상, 기포 발생, 유해가스 발생, 고가 등의 문제점을 해결하고 경화 속도, 경도 등이 향상된 새로운 공예용 조성물의 개발이 요구되고 있는 상황이다.Accordingly, there is a need for the development of a new craft composition that solves the problems of conventional resins, such as yellowing, bubble generation, harmful gas generation, and high cost, and has improved curing speed and hardness.
본 발명은 상술한 종래 기술의 문제점을 해결하기 위한 것으로써, 본 발명의 목적은 반응성 미네랄을 포함하는 주제와 수성 아크릴 레진을 포함하는 경화제가 혼합되어 경화 속도, 경도 등이 향상된 공예용 조성물을 제공하는 것이다.The present invention is intended to solve the problems of the prior art described above, and an object of the present invention is to provide a craft composition having improved curing speed, hardness, etc. by mixing a subject matter including a reactive mineral and a curing agent including a water-based acrylic resin.
본 발명은 상기 과제를 해결하기 위해 반응성 미네랄인 주제와 수성 아크릴 레진인 경화제를 혼합하여 새로운 형태의 공예용 조성물을 제공한다.The present invention provides a new type of craft composition by mixing a subject matter which is a reactive mineral and a hardener which is a water-based acrylic resin to solve the above problems.
본 발명의 일 구현 예로서, 상기 반응성 미네랄은 충북 영동에서 생산되는 일라이트, 백운모, 금운모, 제올라이트, 규조토 등과 유사한 천연광물일 수 있다. As an embodiment of the present invention, the reactive mineral may be a natural mineral similar to illite, muscovite, phlogopite, zeolite, diatomaceous earth, etc. produced in Yeongdong, Chungcheongbuk-do.
본 발명의 일 구현 예로서, 상기 경화제와 주제의 중량비는 1 : 2일 수 있다.As one embodiment of the present invention, the weight ratio of the curing agent and the subject may be 1:2.
본 발명에 따른 공예용 조성물은 반응성 미네랄을 포함하는 주제와 수성 아크릴 레진을 포함하는 경화제가 혼합되어 실온에서 경화되고 경화 속도가 30분 이하로 빠르며, 유해가스가 발생하지 않는 친환경적인 재료이다.The craft composition according to the present invention is an environmentally friendly material that is cured at room temperature by mixing a subject including a reactive mineral and a hardener including a water-based acrylic resin, has a fast curing speed of 30 minutes or less, and does not generate harmful gases.
또한, 우윳빛을 띄는 불투명한 원료에 다양한 수성 조색제를 가미하여 자신만의 개성있고 다채로운 공예품의 구현을 가능하게 하며, 제품 완성 후 도자기처럼 재질이 부드럽고 경도가 높으며, 불에 잘 견디는 방염 소재이다. In addition, by adding various water-based coloring agents to the opaque raw material with a milky color, it is possible to create your own unique and colorful crafts. After the product is completed, it is a soft and hard material like porcelain, and is a flame retardant material that is resistant to fire.

이하, 첨부된 도면을 참조하여 본 발명의 실시 예를 더욱 상세히 설명하기로 한다. 그러나, 본 발명은 이하에서 개시되는 실시 예에 한정되는 것이 아니라 서로 다른 다양한 형태로 구현될 것이며, 단지 본 실시 예들은 본 발명의 개시가 완전하도록 하며, 통상의 지식을 가진 자에게 발명의 범주를 완전하게 알려주기 위해 제공되는 것이다. 도면 상에서 동일 부호는 동일한 요소를 지칭한다.Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and these embodiments are provided only to make the disclosure of the present invention complete and to fully inform those skilled in the art of the scope of the invention. In the drawings, the same reference numerals refer to the same elements.
각 도면의 구성 요소들에 참조부호를 부가함에 있어서, 동일한 구성요소들에 대해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하고 있음에 유의해야 한다. 또한, 본 발명을 설명함에 있어, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 본 발명의 요지를 흐릴 수 있다고 판단되는 경우에는 그 상세한 설명은 생략한다.When adding reference signs to components of each drawing, it should be noted that identical components are given the same signs as much as possible even if they are shown on different drawings. In addition, when describing the present invention, if it is determined that a specific description of a related known configuration or function may obscure the gist of the present invention, the detailed description is omitted.
종래 에폭시 레진은 주로 공업용으로 생산되었는데 이를 공예용으로 바꾸어 사용하는 과정에서 가격이 급격히 오르는 등 시장의 과열 현상이 초래되었고, 경화 과정에서 기포가 발생하기 쉬워 외관이 손상되고 투명도가 저하되는 부작용이 있었다. 이를 방지하기 위해서는 에폭시 레진을 가열하여 점도를 낮추거나 기포가 발생하지 않도록 고가의 탈포기를 사용해야 하는 등의 공정상 불편함이 있었다.Previously, epoxy resins were mainly produced for industrial use, but in the process of changing them to be used for craft purposes, the price rose sharply, resulting in overheating in the market. In addition, bubbles were easily generated during the curing process, which resulted in damage to the appearance and reduced transparency. In order to prevent this, there were inconveniences in the process, such as having to heat the epoxy resin to lower its viscosity or using an expensive degassing machine to prevent bubbles from forming.
또한, 에폭시 레진은 경화시간이 통상적으로 1~3일 정도로서 경화 작업에 많은 시간이 소요되며, 시간이 경과함에 따라 자외선에 의해 열화되는 황변 현상이 발생하기 쉽다.In addition, epoxy resins take a long time to cure, usually 1 to 3 days, and are prone to yellowing over time due to deterioration caused by ultraviolet rays.
나아가, 에폭시 레진은 경화하기 전의 액체나 기화시 발생하는 유해가스를 흡입할 경우, 인체 건강에 큰 악영향을 미치는 단점이 존재한다.Furthermore, epoxy resin has the disadvantage of having a significant negative impact on human health when inhaled as a liquid before curing or when inhaling harmful gases generated during vaporization.
이에, 본 발명은 상술한 에폭시 레진의 문제점을 해결하기 위해 천연광물에서 추출한 반응성 미네랄인 주제와 친환경적인 순수 수성 아크릴 폴리머인 경화제를 혼합하는 것을 특징으로 하는 공예용 조성물을 제공한다.Accordingly, the present invention provides a craft composition characterized by mixing a subject matter, which is a reactive mineral extracted from natural minerals, and a curing agent, which is an environmentally friendly pure water-based acrylic polymer, in order to solve the problems of the above-described epoxy resin.
본 발명의 공예용 조성물은 주제로 반응성 미네랄을 사용하며, 상기 반응성 미네랄은 백운모, 금운모, 일라이트, 제올라이트, 규조토 등과 같은 천연광물 성분을 포함하는 것이다.The craft composition of the present invention uses a reactive mineral as a subject, and the reactive mineral includes a natural mineral component such as muscovite, phlogopite, illite, zeolite, diatomaceous earth, etc.
운모란 내열성, 방수성, 내부식성, 탄성 및 높은 박리성을 가진 천연광물이며, 충북 영동에서 산출되는 일라이트는 고문서 동의보감에도 나타나듯이 의학적, 미용적 약성이 특출하며 본초용법에 '불에 타지 않아 안경이나 화로, 문, 벽채로 사용한다'고 표기되어 있을 만큼 다방면으로 유용한 소재들이다. Mica is a natural mineral that is heat-resistant, waterproof, corrosion-resistant, elastic, and has high exfoliation properties. Illite produced in Yeongdong, North Chungcheong Province, has outstanding medical and cosmetic properties as shown in the ancient document Donguibogam. It is a useful material in many ways, as indicated in the herbal medicine book as being "unflammable, so it is used for glasses, braziers, doors, and wall panels."
천연광물에서 추출한 상기 미네랄 성분들은 세라믹 가구, 대리석 등의 건축재료로서 각광받고 있는데, 주 특징으로 높은 내구성을 가진 방염소재로 인체에 해로운 솔벤트 및 voc를 포함하지 않는다. The above mineral components extracted from natural minerals are in the spotlight as building materials for ceramic furniture, marble, etc., and their main features include being highly durable, flame-retardant materials and not containing solvents or VOCs that are harmful to the human body.
또한, 반응성 미네랄은 오염된 토양과 수질을 정화하고 개선하며 공기 중에 유해 화학물을 흡착하여 실내공기와 습도를 조절하고 곰팡이균을 억제한다. Additionally, reactive minerals purify and improve polluted soil and water quality, adsorb harmful chemicals in the air, regulate indoor air quality and humidity, and inhibit mold and mildew.
무엇보다 공예품 제작과정에서 누수되는 잔여물을 잘게 쪼개어 테라조 스타일로 변형해서 제작할 수 있으며, 작품 완성 후나 사후에 흙과 같이 자연 상태로의 회귀가 가능하여 불필요한 쓰레기를 양산하지 않는다.Above all, the residue that leaks out during the craft production process can be broken down into small pieces and transformed into terrazzo style, and after the work is completed or after death, it can return to its natural state like soil, so it does not produce unnecessary waste.
본 발명의 공예용 조성물은 경화제로 수성 아크릴 레진을 사용하며, 상기 수성 아크릴 레진은 물과 1 : 1 비율로 희석된 에멀전 형태인 것이 바람직하다.The craft composition of the present invention uses a water-based acrylic resin as a hardener, and it is preferable that the water-based acrylic resin is in the form of an emulsion diluted with water at a ratio of 1:1.
본 발명의 공예용 조성물은 경화제로 에폭시 레진이 아닌 수성 아크릴 레진을 사용함에 따라 실온에서 경화시간이 30분 이하로 단축되며, 보다 구체적으로는 경화 개시 후 10분이 경과하면 겔(gel) 형태가 되고, 30분이 경과하면 완전히 굳어져 고형화가 된다.Since the craft composition of the present invention uses a water-based acrylic resin instead of an epoxy resin as a hardener, the curing time at room temperature is shortened to 30 minutes or less. More specifically, the craft composition takes on a gel form 10 minutes after the start of curing, and completely hardens and solidifies after 30 minutes.
상기 경화제와 주제의 중량비는 1 : 2인 것이 바람직하며, 상기 범위에서 경화 속도와 내구성이 향상될 수 있다.It is preferable that the weight ratio of the above hardener and the subject matter be 1:2, and within the above range, the curing speed and durability can be improved.
이하 실시 예를 통하여 본 발명에 대하여 상세하게 설명하기로 한다.The present invention will be described in detail through the following examples.
2019년 전세계적인 코로나19 팬데믹의 여파로 수입에 차질이 생겨 영국에서 수입되는 수성 아크릴레진 제스모나이트가 국내에서 품절 현상을 겪게 되었다. 이때까지 국내에 수성 아크릴레진은 개발되지 않은 상태였으며, 100% 영국 수입 의존도였다. In 2019, due to the global COVID-19 pandemic, imports were disrupted, and Jesmonite, a water-based acrylic resin imported from the UK, became out of stock in Korea. Until then, water-based acrylic resin had not been developed in Korea, and we were 100% dependent on imports from the UK.
국내 레진아트 작가들은 값비싼 영국산 수성 아크릴레진인 제스모나이트를 수입해 쓰다가 그마저도 코로나 여파로 물류에 차질이 생겨 공예활동을 지속할 수 없게 되었다.Domestic resin art artists had been importing and using Jesmonite, an expensive British water-based acrylic resin, but due to the coronavirus, logistics were disrupted and they were unable to continue their craft activities.
이에 몇몇 공예작가분이 우리나라에도 수성 아크릴레진이 있었으면 좋겠다는 바람을 이야기하게 되었고, 이것이 본 발명품의 시초가 되었다. This led several craftsmen to express their wish that water-based acrylic resin could be found in our country, and this became the beginning of this invention.
기존의 수입품 제스모나이트를 꼼꼼히 분석하고 사용해본 결과 승산이 있겠다는 판단이 들었고, 본격적으로 화학 공부를 시작하게 되었다. After carefully analyzing and using the existing imported Jesmonite, I concluded that it had a good chance of success, and began studying chemistry in earnest.
우선 국내에서 반응성 미네랄 성분을 가진 천연광물들과 수성아크릴계 경화제 성분을 가진 여러 재료들을 구입해 각종 화학성분을 비교하고 분석하는 과정을 거쳤다. First, we purchased natural minerals with reactive mineral components and various materials with water-based acrylic hardener components domestically and compared and analyzed their chemical components.
둘의 특성을 파악하고 비율을 조절해가며 수십차례 연구와 실험을 거듭하는 과정에서 마침내 순수 국내산 원료만으로 국내 최초 수용성 아크릴레진을 개발하게 되었다. Through dozens of research and experiments to understand the characteristics of the two and adjust the ratio, we were finally able to develop Korea's first water-soluble acrylic resin using only domestic raw materials.
하기의 표 1의 미카 적정 희석 비율 도표를 참조하면, 수용성 아크릴레진 미카는 베이스가 되는 미네랄 파우더(A제)와 수성아크릴 액상(B제)을 2:1로 배합해 교반했을 때 내구성과 인장강도, 압축강도가 강하고 타 소재와 결합력이 좋아진다는 걸 발견했다. Referring to the appropriate dilution ratio chart of Table 1 below, it was discovered that when the water-soluble acrylic resin mica was mixed with the base mineral powder (A) and the water-based acrylic liquid (B) in a 2:1 ratio and stirred, the durability, tensile strength, and compressive strength were strong, and the bonding strength with other materials was improved.
미네랄 파우더(A제)와 수성아크릴 액상(B제)를 혼합한 후, 곧바로 수성아크릴 조색제를 최대 2%까지 혼합해 믹싱하면 다양한 색깔 표현이 가능해 개성있는 작품 연출이 되었다. After mixing the mineral powder (A) and water-based acrylic liquid (B), you can immediately add up to 2% of water-based acrylic coloring agent to create a variety of colors, allowing you to create unique works.
이에, 기존 해외의 제스모나이트를 사용하던 레진아트 작가분들에게 샘플 자료를 보내 공예품 제작을 의뢰해본 결과, 제스모나이트보다 가격도 저렴할뿐더러 경화속도가 훨씬 빠르고 미네랄 파우더 성분이 더 깨끗하며, 주제와 경화제를 희석하기도 용이해 품질이 더 우수하다는 열광적인 피드백을 받고 본격적인 생산과 판매에 돌입하게 된다.Accordingly, we sent sample materials to resin art artists who were previously using overseas Jesmonite and asked them to make crafts. As a result, we received enthusiastic feedback that not only was it cheaper than Jesmonite, but the curing speed was much faster, the mineral powder content was cleaner, and it was easier to dilute the subject and hardener, so the quality was superior. We then began full-scale production and sales.
본 발명품과 해외 수입품인 제스모나이트를 비교 분석한 데이터는 하기 표 2와 같다. The data comparing and analyzing the present invention with imported Jesmonite are as shown in Table 2 below.
이런 사실을 바탕으로 기존 제스모나이트를 사용하던 국내 레진아트 작가군들이 발빠르게 미카로 옮겨오고 있으며, 다양한 공예품들을 아이디어스 등에 판매해 매출을 극대화하는 효과를 얻고 있다. Based on these facts, domestic resin art artists who previously used Jesmonite are quickly moving to Mica, and are maximizing their sales by selling various crafts to Ideas and other sites.
