인조대리석은 천연 석분이나 광물을 수지성분(아크릴, 불포화폴리에스테르, 에폭시 등)이나 시멘트와 배합하고 각종 안료 및 첨가제 등을 첨가하여 천연석의 질감을 구현한 인조 합성체를 통칭하는데, 대표적으로는 아크릴계 인조대리석, 폴리에스테르 인조대리석 등을 들 수 있다. 이들 아크릴계 인조대리석과 폴리에스테르 인조대리석은 고체 재료에 특유한 강도와 색조를 가지고 있으며, 특히 아크릴계 인조대리석은 우수한 가공성과 내후성을 가지고 있다. 아크릴계 인조대리석은 천연대리석과 비교하여 가볍고 비다공질이며, 천연 대리석에 뒤떨어지지 않는 우아한 색조, 뛰어난 강도 및 내후성을 가지고 있으며, 더욱이 목질과 비견될만한 우수한 가공성를 가지고 있어 천연 대리석과 차별화될 수 있다. 따라서, 아크릴계 인조대리석은 최근 각종 상판재료, 드레싱 테이블, 세면대, 테이블, 벽재, 바닥마루 재료, 가구, 내장재와 같은 다양한 용도에 사용할 수 있다.Artificial marble is a synthetic synthetic material that combines natural stone powder and minerals with resin components (acrylic, unsaturated polyester, epoxy, etc.) and cement, and adds various pigments and additives to realize the texture of natural stone. Artificial marble, polyester artificial marble, etc. are mentioned. These acrylic artificial marble and polyester artificial marble have strength and color tone peculiar to solid materials, and especially acrylic artificial marble has excellent workability and weather resistance. Acrylic artificial marble is lighter and more non-porous than natural marble, and has an elegant hue that is inferior to natural marble, excellent strength and weather resistance, and furthermore, it can be distinguished from natural marble because of its excellent workability comparable to wood. Therefore, acrylic artificial marble can be used in various applications such as various top plate materials, dressing tables, wash basins, tables, wall materials, flooring materials, furniture, interior materials.
자연상태에서는 공기 중에 전기적 성질을 가진 공기에너지가 존재하며, 음이온과 양이온으로 나눌 수 있다. 이중 음이온은 산성화된 인체를 환원시키는 역할을 하고 물을 약 알칼리화시킴으로써 면역기능을 높이고 혈액을 정화한다. 아울러 세포의 신진대사를 촉진시키며, 체내가 음이온화되면 피부는 플러스화되어 플러스 이온인 먼지 등이 피부에 붙지 않게 되므로 알레르기 및 아토피 등의 증상이 격감하게 된다. 최근 들어 산업발달에 따른 대기오염으로 인해 대기 중에 음이온과 양이온의 균형이 깨어져 사람들의 건강에 악영향을 주고 있다. 이에 따라 음이온을 인위적으로 발생시켜 그 균형을 맞추고자 하는 노력들이 여러 분야에 걸쳐 진행되어져 왔다.In nature, air energy with electrical properties exists in the air and can be divided into anions and cations. Double anions serve to reduce the acidified human body and increase the immune function and cleanse the blood by weakly alkalizing water. In addition, it promotes the metabolism of cells, and when the body is anionized, the skin becomes positive, so that the positive ions, dust, etc. do not adhere to the skin, thereby reducing symptoms such as allergies and atopy. Recently, due to air pollution caused by industrial development, the balance of anions and cations in the air is broken, which adversely affects the health of people. Accordingly, efforts have been made in various fields to artificially generate anions and balance them.
한편, 원적외선은 비가시광선에 속하는 에너지파의 일종으로, 인체 내의 세포를 구성하는 분자에 방사되어 세포를 1분에 2,000번 이상 미세하게 진동시켜 주는데, 이 과정에서 열에너지가 발생하고 모세혈관의 강화로 혈액순환이 개선되며 인체 내의 노폐물이 자연스럽게 배출되게 된다. 또한, 원적외선은 특유의 복사 침투력에 의해 생체 깊숙이 흡수되면서 생체 에너지 순환과 생리현상을 활성화시킴으로써 건강 증진에 도움을 준다.On the other hand, far infrared rays are a kind of energy waves belonging to invisible light, and are radiated to molecules constituting cells in the human body to vibrate the cells more than 2,000 times per minute. In this process, heat energy is generated and the capillaries are strengthened. This improves blood circulation and naturally discharges waste products from the body. In addition, far-infrared rays are absorbed deep into the living body by the unique radiation penetrating power, thereby helping to promote health by activating the biological energy circulation and physiology.
종래에는 원적외선과 음이온을 발생시키는 황토, 제올라이트, 맥반석, 옥 등 주로 천연 광물을 수지에 첨가하여 목적하는 효과를 얻었으나, 이런 경우 자연석의 음이온 함량에 한계가 있어 수지에 첨가할 경우 그 강도가 약해 원래의 효과를 크게 반감시키는 결과를 가져왔다. 또한 원하는 만큼의 음이온 발생량을 얻기 위해서는 광물을 적정수준 이상 사용하는 것이 불가피하여 색상변화 및 물성변화 등 악영향을 초래하였다. 또한 이런 천연광물들은 항균효과가 없고 그 순도가 높지 않으며 불순물 함량이 많아 인조대리석의 표면에 원하지 않은 모양의 이물(잡티)현상이 발생하고, 그 천연의 색상으로 인하여 인조대리석 색상의 적용에 많은 제약이 따른다.Conventionally, natural minerals such as ocher, zeolite, elvan, and jade, which generate far infrared rays and anions, are mainly added to the resin to obtain the desired effect. However, in this case, the anion content of the natural stone is limited, and the strength is weak when added to the resin. The result was a large halve of the original effect. In addition, in order to obtain the desired amount of negative ions generated, it is inevitable to use minerals more than the proper level, resulting in adverse effects such as color change and physical property change. In addition, these natural minerals do not have an antibacterial effect, their purity is not high, and the impurities have a high content of impurities, causing undesired foreign matters on the surface of artificial marble, and due to their natural color, there are many restrictions on the application of artificial marble colors. This follows.
여기에다 지금까지는 표면처리나 별도의 코팅층을 아크릴계 인조대리석에 적용한 예는 없었고, 일부 적용되었던 표면처리가 가능한 불포화폴리에스테르계 등 일부 인조대리석에는 제한된 색상 및 음이온 방출량 등으로 실용화 단계에 이르지 못하고 있다.In addition, until now, no surface treatment or a separate coating layer was applied to acrylic artificial marble, and some artificial marble such as unsaturated polyester based surface treatment, which has been partially applied, has not been put into practical use due to limited color and anion emission.
본 발명자들은 인간의 건강증진에 기여할 수 있는 신기능의 아크릴계 인조대리석을 개발하고자 연구한 결과, 중합 가능한 아크릴계 단량체와 그 중합체로 이루어지는 아크릴계 시럽에 항균효과를 갖고 음이온 및 원적외선 방출기능을 갖도록 제조된 음이온 세라믹을 첨가하고 무기충진제(주로 수산화알루미늄)를 분산시킨 후 경화시켜 제조한 아크릴계 인조대리석이 인조대리석 고유의 물성을 유지하면서도 기존의 인조대리석보다 월등히 많은 음이온과 원적외적을 방출함을 확인하여 본 발명을 완성하게 되었다.The present inventors have studied to develop a new functional acrylic artificial marble that can contribute to the improvement of human health, and as a result, an anionic ceramic manufactured to have an antimicrobial effect on an acrylic syrup composed of a polymerizable acrylic monomer and a polymer thereof and have an anion and far infrared ray emitting function. The present invention was confirmed that the acrylic artificial marble prepared by adding and dispersing the inorganic filler (mainly aluminum hydroxide) and hardening emits much more anions and far infrared rays than the existing artificial marble while maintaining the intrinsic properties of artificial marble. It was completed.
따라서, 본 발명은 상술한 종래의 문제를 해결하기 위한 것으로, 천연광물을 대신하여 백색도가 높고 불순물의 함량이 낮으며 항균효과를 갖고 인위적으로 조절된 높은 음이온 방출수를 갖는 무기물을 첨가함으로써 기존의 아크릴계 인조대리석이 갖고 있는 우수한 색상, 표면질감 및 고유의 기계적 특성을 유지하면서도 항균효과 및 음이온과 원적외선 방출효과를 갖는 기능성 아크릴계 인조대리석을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention is to solve the above-mentioned conventional problems, by replacing the natural minerals by adding inorganic substances having high whiteness, low impurities content, antibacterial effect and artificially controlled high anion-emitting water. It is an object of the present invention to provide a functional acrylic artificial marble having an antibacterial effect and anion and far infrared ray emitting effect while maintaining excellent color, surface texture and inherent mechanical properties of the acrylic artificial marble.
본 발명의 다른 목적은 항균효과 및 음이온과 원적외선 방출효과를 갖으며, 천연대리석과 유사한 표면 형태를 갖는 기능성 아크릴계 인조대리석의 제조방법을 제공하는 것이다.Another object of the present invention is to provide a method for producing a functional acrylic artificial marble having an antimicrobial effect and anion and far infrared ray emitting effect, and having a surface form similar to that of natural marble.

It is manufactured.

Prepared by grinding to a suitable size.
본 발명에서는 음이온 세라믹으로서 바이오세라사의 Biocera-TO을 사용하였다. 또한, 본 발명에서 사용되는 음이온 세라믹은 목적하는 항균력, 백색도, 음이온 방출수 및 원적외선 방사율을 달성하기 위하여, 적어도 항균력이 90% 이상, 자체의 백색도가 80 이상, 음이온 방출수가 3,000 이상, 원적외선 방사율이 90% 이상인 것을 사용하는 것이 바람직하다. 또한, 상기 음이온 세라믹의 표면을 이산화티탄으로 코팅하여 백색도를 향상시키는 것이 가능하다.In the present invention, Biocera-TO of Biocera Corporation was used as the anion ceramic. In addition, in order to achieve the desired antimicrobial power, whiteness, anion-emitting water and far-infrared emissivity, the anionic ceramic used in the present invention has at least 90% antimicrobial power, its own whiteness of 80 or more, anion-emitting water of 3,000 or more, and far-infrared emissivity. It is preferable to use 90% or more. In addition, it is possible to improve the whiteness by coating the surface of the anionic ceramic with titanium dioxide.
음이온 세라믹의 바람직한 함량은 아크릴 시럽 100 중량부에 대하여 1 내지 15 중량부이다. 만일 1 중량부 미만이면 최종 제품이 충분한 음이온을 발생할 수 없고, 15 중량부를 초과하게 되면 무기 충전물과의 배합시 점도 상승과 열적성질의 저하가 심해지며 음이온 방출량의 증가폭도 줄어들어 제조원가 상승에 비하여 그 적용효율이 감소함으로써 제품의 경쟁력이 떨어지게 된다.The preferred content of the anionic ceramic is 1 to 15 parts by weight based on 100 parts by weight of the acrylic syrup. If it is less than 1 part by weight, the final product may not generate sufficient anions, and if it exceeds 15 parts by weight, the viscosity increases and the thermal properties deteriorate when combined with inorganic fillers, and the increase in anion emission is reduced, which is higher than the manufacturing cost. The reduced efficiency makes the product less competitive.
본 발명에서 아크릴 시럽의 중합가능한 단량체로는 비닐계 단량체가 사용되며, 바람직하게는 아크릴 단량체가 좋다. 구체적으로 상기 아크릴 시럽은 메틸메타크릴레이트, 에틸메타크릴레이트, 부틸메타크릴레이트, 2-에틸헥실메타크릴레이트,벤질메타크릴레이트 및 글리시딜메타크릴레이트 중에서 선택되는 메타크릴레이트 단량체 단독 또는 2종 이상의 혼합물이며, 메타크릴레이트 단량체 및 그 일부가 중합된 중합체의 혼합물이 사용될 수도 있다. 이들 중에서 메틸메타크릴레이트가 특히 바람직하다. 시럽내의 중합체의 함량은 10 내지 50 중량부인 것이 바람직하다.In the present invention, as the polymerizable monomer of the acrylic syrup, a vinyl monomer is used, preferably an acrylic monomer. Specifically, the acrylic syrup is a methacrylate monomer selected from methyl methacrylate, ethyl methacrylate, butyl methacrylate, 2-ethylhexyl methacrylate, benzyl methacrylate and glycidyl methacrylate alone or two. Mixtures of species or more, and a mixture of polymers in which methacrylate monomers and a portion thereof are polymerized may be used. Of these, methyl methacrylate is particularly preferred.

상기 무기 충진제의 바람직한 함량은 아크릴 시럽 100 중량부에 대하여 100 내지 200 중량부이다. 혼합되는 양이 너무 많을 경우 점도상승, 경화속도 지연 등 작업성 저하와 인조대리석의 기계적 특성 저하를 초래하고, 너무 적을 경우에는 인조대리석의 난연성이 약해지고 색조가 소실된다.The preferred content of the inorganic filler is 100 to 200 parts by weight based on 100 parts by weight of the acrylic syrup. Too much mixing results in lower workability such as viscosity increase and delay in hardening speed and lower mechanical properties of artificial marble. When too small, the flame resistance of artificial marble becomes weak and color tone is lost.
또한, 상기 수산화 알루미늄의 입자크기가 너무 클 경우 인조대리석의 물리적 특성이 저하되고, 너무 작을 경우 인조대리석의 광 투과성능이 떨어지는 경향이 있으므로, 입자크기가 5 내지 100 마이크론인 수산화 알루미늄을 사용하는 것이 바람직하다.In addition, if the particle size of the aluminum hydroxide is too large, the physical properties of the artificial marble is lowered, and if the particle size is too small, the light transmission performance of the artificial marble is inferior, it is preferable to use aluminum hydroxide having a particle size of 5 to 100 microns. desirable.
