이하 본 발명의 구체적인 내용을 하기에 상세히 설명한다.
Hereinafter, the present invention will be described in detail.
본 발명은 은나노(Ag-nano) 항균제를 아크릴 수지에 함유시킴으로써 항균성을 갖는 아크릴 판을 제공하는 효과를 갖는다.
The present invention has an effect of providing an acrylic plate having antimicrobial properties by containing an Ag-nano antimicrobial agent in an acrylic resin.
본 발명은 메타크릴산 메틸에스테르(MMA)에 가소제를 첨가하여 중합반응을 거쳐 판상(板狀)으로 제조되는 아크릴 판에 관한 것으로, 은나노 항균제를 사용한 항균성 아크릴 판 및 그 제조방법에 관한 것이다.The present invention relates to an acrylic plate produced by adding a plasticizer to a methacrylic acid methyl ester (MMA) and polymerizing the same, and relates to an antibacterial acrylic plate using a silver nano-antibacterial agent and a method for producing the same.
본 발명의 항균성 아크릴 판은 입경이 0.8 ㎛ 이하이고, 함수율이 0.5 % 이하이며, 은(Ag) 함량이 4.0 % 이상인 은나노 항균제 0.5∼2.0 중량%를 아크릴 수지에 함유시켜 제조되는 것을 그 특징으로 한다. The antimicrobial acrylic plate of the present invention is characterized in that 0.5 to 2.0% by weight of a silver nano-sized antimicrobial agent having a particle size of 0.8 μm or less, a water content of 0.5% or less, and a silver (Ag) content of 4.0% .
MMA에 가소제를 부가하여 중합기에서 중합하여 아크릴 판을 제조하는 공정은 이미 공지된 것으로, 아크릴 판을 제조함에 있어서 널리 채용되고 있는 방법이다. 본 발명에서는 은나노 항균제를 사용하여 항균성 아크릴 판을 제조하기 위한 것이다. A process of adding a plasticizer to MMA and polymerizing it in a polymerization reactor to produce an acrylic plate is well known and is widely used in the production of acrylic plates. In the present invention, an antimicrobial acrylic plate is manufactured using a silver nano-antibacterial agent.
본 발명에서 사용되는 가소제로는 종래의 아크릴 판을 제조하는 것과 같은 AIBN (2,2'-azo-bis(isobutyronitrile)) 또는 ABN (2,2'-azo-bis (2-methylbutyronitrile)) 등이 바람직하게 사용된다.As the plasticizer used in the present invention, AIBN (2,2'-azo-bis (isobutyronitrile)) or ABN (2,2'-azo-bis (2-methylbutyronitrile) Is preferably used.
본 발명에서 은나노 항균제는 전체 아크릴 수지에 대하여 0.5∼2.0 중량%를 함유시키는 것이 바람직하다. 은나노 항균제가 0.5 중량% 미만이면 충분한 항균성을 나타낼 수 없고, 2.0 중량%를 초과하면 은나노 항균제를 불필요하게 함유하게 된다. In the present invention, the silver nano-antibacterial agent is preferably contained in an amount of 0.5 to 2.0% by weight based on the entire acrylic resin. If the silver nano-size antimicrobial agent is less than 0.5% by weight, sufficient antimicrobial activity can not be exhibited. If it exceeds 2.0% by weight, silver nano-antimicrobial agent is unnecessarily contained.
본 발명의 항균성 아크릴 판은 MMA 100 중량부에 가소제 0.1～5 중량부를 중합기에서 중합시켜 포드컵(Ford Cup) 점도 2～3 분의 점도를 형성시키고, 상기 점도가 형성된 중합물에 0.5∼2.0 중량%의 은나노 항균제를 혼합하고, 상기 혼합물을 유리틀 금형으로 캐스팅하여 제조되는 것을 그 특징으로 한다. 포드컵 점도계는 일정용량의 원통형 용기에 측정하고자 하는 중합물을 가득 채워 그 바닥에 형성된 구멍을 통하여 그 중합물이 전부 유출되는데 걸리는 시간으로 점도를 계측한다. 이 방법은 점도가 형성된 중합물에 은나노 항균제를 혼합하기 때문에, 원하는 양의 은나노 항균제를 부가할 수 있다.
In the antimicrobial acrylic plate of the present invention, 0.1 to 5 parts by weight of a plasticizer is polymerized in 100 parts by weight of MMA to form a viscosity of 2 to 3 minutes in a Ford Cup viscosity, and 0.5 to 2.0 parts by weight % Of a silver nano antimicrobial agent, and casting the mixture into a glass mold. The pod cup viscometer measures the viscosity of a cylindrical container filled with a polymeric substance to be measured and the time it takes for the polymer to completely flow out through a hole formed in the bottom thereof. Since this method mixes the silver nanoparticles with the viscosity-formed polymer, a desired amount of silver nanoparticles can be added.
본 발명의 방법에 따라 제조된 MMA 중합물을 원료로 하여 유리틀 금형을 이용한 캐스팅 방법에 의하여 항균성 아크릴 판을 제조한다. 유리틀 금형을 이용한 캐스팅 방법은 아크릴 판을 제조하는 종래의 방법으로 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진자에 의하여 용이하게 실시될 수 있다. An antimicrobial acrylic plate is prepared by a casting method using a glass mold with the MMA polymeric material prepared according to the method of the present invention as a raw material. The casting method using a glass mold is a conventional method of manufacturing an acrylic plate, which can be easily performed by a person having ordinary skill in the art to which the present invention belongs.

The MMA polymer prepared in the present invention is injected into a glass mold, cured in a water bath at 30 to 60 ° C, steamed at 100 to 120 ° C for 30 to 60 minutes in a water bath, The mold is cooled to produce an acrylic plate. The size of the acrylic plate is 3 × 6, and its thickness is usually 3 mm, 5 mm, and 8 mm. However, the size and thickness are not necessarily limited thereto, and may be modified to any extent depending on the application.
본 발명의 항균성 아크릴 판을 제조하기 위하여 은나노 항균제가 함유된 마스터배치 칩을 제조하여 사용할 수 있는데, 이 경우에는 입경이 0.8 ㎛ 이하이고, 함수율이 0.5 % 이하이며, 은(Ag) 함량이 4.0 % 이상인 은나노 항균제 15∼25 중량%를 아크릴 수지에 함유시켜 마스터배치 칩을 제조하고, 이 마스터배치 칩을 이용하여 항균성 아크릴 판을 제조한다. In order to produce the antimicrobial acrylic plate of the present invention, a masterbatch chip containing a silver nano-scale antimicrobial agent may be prepared and used. In this case, the grain size is 0.8 μm or less, the water content is 0.5% or less, the silver content is 4.0% By weight of a silver nano-sized antimicrobial agent is contained in an acrylic resin to prepare a master batch chip, and an antibacterial acrylic plate is prepared using this master batch chip.
