In addition, when disposing of the biochemically decomposable vaporizable rustproof film for silver, copper, and aluminum products prepared according to the present invention, the vaporizable rustproof film of the present invention is surrounded by a metal having a high thermal conductivity of at least 200 Kcal / mhr ° C., in particular a copper nanometal. Primary biochemical decomposition that transfers heat generated in natural environment faster than general film and oxidizes large molecular chain of polyethylene resin with large molecular chain structure into small molecular chain by using heat transferred to vaporizable rustproof film. As the microorganisms are proliferated by dextrin and hydroxy ethyl cellulose, secondary biochemical decomposition occurs in which the vaporizable rust preventive film of the present invention is decomposed by these microorganisms.
이와 같이 구리나노금속, 덱스트린 및 하이드록시 에틸 셀룰로오스에 의해 본 발명의 기화성 방청필름은 생화학분해가 발생되므로, 일반 필름과는 달리 소각처리할 필요가 없으므로 소각처리에 의한 위해물질이 발생되지 않고, 매립시에도 분해가 빨리 이루어져서 환경오염의 발생을 방지할 수 있다.As such, the vaporizable rust preventive film of the present invention is biochemically decomposed by copper nano metal, dextrin, and hydroxy ethyl cellulose.

It can be decomposed quickly at the time of the environment to prevent the occurrence of environmental pollution.
본 발명의 은, 구리 및 알루미늄 제품용 생화학분해성 기화성 방청필름은 폴리에틸렌수지 1000중량부에 대해서 벤조산 나트륨은 0.5중량부 내지 1.5중량부이고, 벤조트리아졸은 0.5중량부 내지 1.5중량부이고, 토리트리아졸은 1.0중량부 내지 2.0중량부이고, 몰리브덴산나트륨은 0.4중량부 내지 1.5중량부이고, 산화아연은 0.1중량부 내지 0.6중량부이고, 덱스트린은 0.1중량부 내지 0.6중량부이고, 하이드록시 에틸 셀룰로오스는 0.8중량부 내지 1.5중량부이고, 스테아린산 아연은 1.0중량부 내지 1.7중량부이고, 폴리에틸렌 왁스는 1.0중량부 내지 2.0중량부이고, 알파 올레핀계 중합체는 50중량부 내지 150중량부로 형성된다.The biochemically decomposable vaporizable rust preventive film for silver, copper, and aluminum products of the present invention is 0.5 to 1.5 parts by weight of sodium benzoate, 0.5 to 1.5 parts by weight of benzotriazole, and toritria based on 1000 parts by weight of polyethylene resin. The sol is 1.0 parts by weight to 2.0 parts by weight, the sodium molybdate is 0.4 parts by weight to 1.5 parts by weight, the zinc oxide is 0.1 parts by weight to 0.6 parts by weight, the dextrin is 0.1 parts by weight to 0.6 parts by weight, and the hydroxy ethyl The cellulose is 0.8 parts by weight to 1.5 parts by weight, the zinc stearate is 1.0 parts by weight to 1.7 parts by weight, the polyethylene wax is 1.0 parts by weight to 2.0 parts by weight, and the alpha olefin polymer is formed by 50 parts by weight to 150 parts by weight.
벤조산나트륨, 벤조트리아졸, 토리트리아졸, 몰리브덴산나트륨 및 산화아연은 방청을 위한 성분으로, 상기 적정 중량보다 낮게 혼합할 경우 방청력이 감소되게 되고, 적정 중량보다 클 경우에는 방청성의 균형이 깨져서 발청이 발생될 수 있다.Sodium benzoate, benzotriazole, toritriazole, sodium molybdate, and zinc oxide are components for rust prevention, and when mixed below the proper weight, the rust preventive power is reduced, and when the weight is higher than the proper weight, the balance of rust resistance is broken. An outbreak may occur.
덱스트린과 하이드록시 에틸 셀룰로오스는 적정치 이하일 경우 미생물 증식이 활발하지 못하게 되어 생화학분해가 원활하지 못하고, 적정치 보다 클 경우에는 필름의 물성을 약화시킨다. Dextrin and hydroxy ethyl cellulose are less than the optimum value of the microbial proliferation is not active, the biochemical decomposition is not smooth, if larger than the appropriate value weakens the physical properties of the film.
또한, 스테아린산 아연은 분산제로서 제1혼합물과 제2혼합물의 혼합교반시 교반이 원활하게 이루어지기 위해 사용된다.In addition, zinc stearate is used as a dispersant to smoothly stir when mixing the first mixture and the second mixture.

When the polyethylene wax is lower than the appropriate weight, the mixing of the rust-preventing agents mixed in the first mixing stirring step (S10) and the polyethylene resin mixed in the third mixing stirring step (S40), which is a post-process, is not performed smoothly. If it is larger than the appropriate weight, the vaporizable rust preventive film of the present invention becomes too flexible and the bursting strength or tensile strength is not good.
알파 올레핀계 중합체는 압출단계(S50)에서 제3혼합물의 필름압출시 압출되 는 필름의 인장강도를 높여주기 위해 혼합되어진다.The alpha olefin polymer is mixed in order to increase the tensile strength of the film extruded during the extrusion of the third mixture film in the extrusion step (S50).

The rust test was performed by putting the sealed packaged specimen in a thermostat maintained at 50 ° C and kept at 50 ° C, and opening the specimens after 72 hours. The chlorine spray test was conducted for 5% concentration of sodium chloride (NaCl). ) After 72 hours in the atmosphere of 35 ℃ temperature in the solution was observed whether the occurrence of rust.
상기 표 1에 나타난 바와 같이 본 발명에 의한 생화학분해성 기화성 방청필름은 일반필름에 비해 발청현상이 발생되지 않음을 알 수 있고, 이로 인해 방청처리가 우수한 것을 확인할 수 있다.As shown in Table 1, it can be seen that the biochemically decomposable vaporizable rust preventive film according to the present invention does not generate a rusting phenomenon as compared to the general film, and thus it can be confirmed that the rust preventive treatment is excellent.
