본 발명은 은(銀)나노 콜로이드 및 자성재료를 함유하는 폴리카보네이트 수지관을 구비한 쇼핑카트에 관한 것이다. The present invention relates to a shopping cart having a polycarbonate resin tube containing silver nano colloid and a magnetic material.
대형 할인매장 및 백화점에서 사용되는 통상의 쇼핑카트는 여러 사람이 사용하기 때문에 쇼핑카트의 손잡이에는 세균 등이 서식하고 있어서, 쇼핑카트를 이용하는 사람들에의 건강과 위생에 좋지 않은 영향을 미친다.Since ordinary shopping carts used in large discount stores and department stores are used by many people, the handles of the shopping carts contain bacteria and the like, which adversely affects the health and hygiene of those who use the shopping carts.
이에 항균성분을 함유한 쇼핑카트가 절실히 요구되고 있다.There is an urgent need for a shopping cart containing an antimicrobial component.
상기와 같은 이유로 대한민국 등록실용신안 제20-424227호의 항균 쇼핑카트 손잡이 튜브 및 이를 구비한 항균 쇼핑카트는 튜브가 담체로 사용되는 고분자에 포획된 수 개의 은 나노 입자를 포함하되, 상기 은 나노 입자의 각각의 크기는 대략 1-2nm이고, 상기 은 나노 입자를 포함한 상기 고분자의 각각의 크기는 대략 6-25nm이며, 상기 손잡이 튜브의 전체 중량과 상기 은 나노 입자를 포함한 상기 고분자의 중량의 비율이 대략 1,000,000g 대 50 내지 100g인 것을 특징으로 하는 항균 쇼핑카트 손잡이 튜브 및 이를 구비한 항균 쇼핑카트에 관한 것이다.For the same reason, the antimicrobial shopping cart handle tube of Korean Utility Model Registration No. 20-424227 and the antimicrobial shopping cart having the same include several silver nanoparticles trapped in a polymer in which the tube is used as a carrier. Each size is approximately 1-2 nm, and each size of the polymer including the silver nanoparticles is approximately 6-25 nm, and the ratio of the total weight of the handle tube to the weight of the polymer including the silver nanoparticles is approximately An antimicrobial shopping cart handle tube and an antimicrobial shopping cart having the same are characterized in that 1,000,000g vs. 50 to 100g.
그러나 상기 항균 쇼핑카트 손잡이 튜브는 은 나노 입자를 포함한 고분자 입자의 크기는 6-25nm이고, 1-2nm의 은 나노 입자를 튜브제작에 필요한 합성수지에 은 성분을 포함하기 위해 담체로 사용되는 레진(resin)의 투입량을 제어함으로써, 튜브 전체에 고르게 은 입자가 분포되도록 한다. 그러나 상기 은 나노 입자를 포함한 레진(resin)의 투입량이 많아 질 때에는, 손잡이 튜브를 구성하는 합성수지의 강도의 저하 및 투명도의 저하 등이 수반되는 문제점이 있었으며, 은 나노 성분만을 함유하고 있어서, 항균성이외에 유해전자파 차단 효과가 많지 않은 단점이 있었다.However, the antimicrobial shopping cart handle tube has a resin particle size of 6-25 nm, including silver nanoparticles, and a resin that is used as a carrier to include silver components in the synthetic resin required for tube production. By controlling the dose of), the silver particles are evenly distributed throughout the tube. However, when the amount of the resin containing the silver nanoparticles is increased, there is a problem in that the strength of the synthetic resin constituting the handle tube and the decrease in transparency are accompanied, and since only the silver nano component is contained, There was a disadvantage that the harmful electromagnetic wave blocking effect is not much.
상기와 같은 문제점을 해소하기 위해 본 발명의 은(銀)나노 콜로이드 및 자성재료를 함유하는 폴리카보네이트 수지관을 구비한 쇼핑카트를 제공함으로써, 항균성이 우수하면서도 투명도 및 내구성이 뛰어나며, 인체에 유해한 전자파를 효과적으로 차단할 수 있는 것이다. In order to solve the above problems, by providing a shopping cart provided with a polycarbonate resin tube containing the silver nano-colloid and magnetic material of the present invention, excellent antibacterial and excellent transparency and durability, harmful electromagnetic waves to human body It can effectively block the.
본 발명의 은(銀)나노 콜로이드 및 자성재료를 함유하는 폴리카보네이트 수지관을 구비한 쇼핑카트에 사용되는 폴리카보네이트는 평균 분자량이 10,000내지 30,000, 바람직하게는 15,000내지 25,000이고, 은(銀)나노 콜로이드는 에틸알코올 용액에 1 내지 3나노미터의 은(銀)을 함침시킨 콜로이드 상태의 용액을 사용한다. 이때 사용되는 은(銀)의 순도는 95% 이상이다.The polycarbonate used in the shopping cart having the polycarbonate resin tube containing the silver nanocolloid and the magnetic material of the present invention has an average molecular weight of 10,000 to 30,000, preferably 15,000 to 25,000, and silver nano The colloid is a colloidal solution in which 1 to 3 nanometers of silver is impregnated into an ethyl alcohol solution. The purity of silver used at this time is 95% or more.
또한 전자파 흡수기능을 부여하기 위하여 Mn-Zn-페라이트, Ni-Zn-페라이트 및 Mg-Zn-페라이트로 이루어진 군으로부터 1종의 자성재료를 선택한다. 이때 사용되는 자성체의 입자 크기는 0.5㎛ 내지 1.0㎛이 바람직하며, 0.5㎛ 미만이면 전자파의 흡수능력이 떨어지고, 1.0㎛을 초과하면 수지조성물로서의 가공성이 현저히 떨어지게 된다.In addition, one type of magnetic material is selected from the group consisting of Mn-Zn-ferrite, Ni-Zn-ferrite and Mg-Zn-ferrite in order to give an electromagnetic wave absorption function. In this case, the particle size of the magnetic material used is preferably 0.5 μm to 1.0 μm. If the particle size is less than 0.5 μm, the absorbing ability of electromagnetic waves is lowered.
또한 황변현상을 방지하기 위하여 활제류를 첨가할 수 있는데, 스테아린산 칼슘, 스테아린산 바륨, 스테아린산 마그네슘 등을 사용할 수 있다.In addition, lubricants may be added to prevent yellowing, and calcium stearate, barium stearate, magnesium stearate, and the like may be used.
