In addition, since curdlan is used, the durability is good, and the fine dust filtering effect is excellent because it has a three-dimensional network structure by open cells.
이하에서는 본 발명을 좀 더 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail.
본 발명의 제조방법을 살펴보면 다음과 같다. Looking at the manufacturing method of the present invention is as follows.
1) 원료혼합과정1) Raw material mixing process
물 100부피부에 폴리비닐알코올 5~25부피부를 넣고 100℃ 정도로 가열하여 폴리비닐알코올을 용해시킨 다음, 5℃ 정도로 냉각시킨다. 이어서 디메틸술폭사이드 10~15부피부와 커들란 2~10부피부를 첨가하여 고르게 잘 교반시킨 다음, 90℃ 정도로 가열한 후 냉각시켜서 원료혼합액을 만든다.Add 5 to 25 parts by volume of polyvinyl alcohol to 100 parts by volume of water, heat to about 100 ° C to dissolve polyvinyl alcohol, and then cool to about 5 ° C. Subsequently, 10 to 15 parts by volume of dimethyl sulfoxide and 2 to 10 parts by volume of curdlan are added, stirred well, heated to about 90 ° C, and then cooled to prepare a raw material mixture.
폴리비닐알코올(Polyvinyl alcohol)은 수용성 수지로서 생분해성을 가지며, 인체에 무해하며, 화장품, 의료용 삽입보형물, 식품포장재 등 다양한 용도로 사용된다. Polyvinyl alcohol (Polyvinyl alcohol) is a water-soluble resin, has biodegradability, is harmless to the human body, and is used for various purposes such as cosmetics, medical implants, and food packaging materials.
디메틸술폭사이드(Demethyl sulfoxide)는 극성이 강하고 흡습성도 높은 유기용매로서, 인체에 대한 독성이 적고, 진통 및 항염증을 포함하는 다양한 약리적 활성을 가진다. Dimethyl sulfoxide (Demethyl sulfoxide) is an organic solvent with strong polarity and high hygroscopicity, has low toxicity to the human body, and has various pharmacological activities including analgesia and anti-inflammatory.
그리고 커들란(curdlan)은 β-1,3-글루칸이라고도 하는데, 알칼리게네스 파에칼리스(Alcaligenes faecalis)와 종양균(Agrobacterium)에서 생산된 다당류를 분리ㅇ정제하여 얻어지는 것으로서 글로코스의 고분자량 중합체이다. 흰색 또는 흰색과 유사한 색의 가루로서, 물 분산액을 80℃ 이상으로 가열하면 열불가역성의 겔을 형성한다. 이러한 커들란은 젤리, 면류, 케이크, 식육가공품 등에 증점제, 결착제, 피막형성제, 겔화제 등으로 사용된다. 이러한 커들란이 사용되면 제조되는 폼재의 인장강도가 증가되어 내구성 등의 기계적인 물성이 좋아진다. Curdlan, also called β-1,3-glucan, is a high molecular weight polymer of glucose obtained by isolating and purifying polysaccharides produced by Alcaligenes faecalis and Agrobacterium. . It is a white or white-like powder, which forms a thermo-irreversible gel when a water dispersion is heated above 80 °C. Such curdlan is used as a thickener, binder, film forming agent, gelling agent, etc. in jellies, noodles, cakes, and processed meat products. When such curdlan is used, the tensile strength of the foam material to be manufactured is increased, and mechanical properties such as durability are improved.
2) 원료혼합액의 점도조절과정2) Viscosity control process of raw material mixture
성형을 위해서는 원료혼합액의 점도를 높여 유동성을 저하시킬 필요가 있는데, 이를 위해 원료혼합액에 개미산 등의 약산을 첨가하여 원료혼합액의 pH를 pH5 정도의 약산성으로 조절하고, 아니스알데하이드 1~5부피부 첨가하여 고르게 잘 교반시킨다.For molding, it is necessary to increase the viscosity of the raw material mixture to reduce fluidity. To this end, a weak acid such as formic acid is added to the raw material mixture to adjust the pH of the raw material mixture to a weak acidity of about pH 5, and 1 to 5 parts by volume of anisaldehyde is added. and stir well evenly.
아니스알데하이드(Anisaldehyde)는 벤젠고리에 알데하이드기와 메톡시기가 치환된 유기화합물이다. 강한 방향을 내는 무색의 투명한 액체로서 인체에 무해하다. 베이커리 제품, 아이스크림에 착향료로 사용되며, 의약품이나 향수제조에도 사용된다. Anisaldehyde is an organic compound in which an aldehyde group and a methoxy group are substituted in a benzene ring. It is a colorless, transparent liquid with a strong aroma, harmless to the human body. It is used as a flavoring agent in bakery products and ice cream, and is also used in pharmaceuticals and perfumery.
이와 같이 처리하면 원료혼합액의 점도가 상승되어 원료혼합액이 페이스트상태가 된다.When treated in this way, the viscosity of the raw material mixture is increased and the raw material mixture is in a paste state.
3) 수용성 기포형성제 혼합과정3) Water-soluble foaming agent mixing process
페이스트상태의 원료혼합액에 전분, 텍스트린, 수용성 무기염 등의 수용성 기포형성제를 첨가하고 고르게 분산시킨다. Add water-soluble foam-forming agents such as starch, dextrin, and water-soluble inorganic salt to the mixture of raw materials in a paste state and disperse them evenly.
상기 수용성 기포형성제는 합성수지의 습식발포에 흔히 사용되는 성분들로서, 후술하는 바와 같이, 수세과정에서 물에 용해되어 제거됨에 따라 반가공블록이 폼화된다. 폼재의 기공율, 기공크기 등에 따라 폼재의 흡수율이 달라지므로 폼재가 소요되는 수준의 흡수율을 가지도록 수성용 기포형성제의 첨가량의 조절하여 폼재의 기공율, 기공크기 등을 조절한다. The water-soluble foam-forming agent is a component commonly used in wet foaming of synthetic resin, and as will be described later, the semi-processed block is foamed as it is dissolved in water and removed during the water washing process. Since the water absorption rate of the foam material varies depending on the porosity and pore size of the foam material, the porosity and pore size of the foam material are adjusted by adjusting the addition amount of the water-based foam former so that the foam material has the required water absorption rate.
4) 성형과정4) Molding process
페이스트상태의 원료혼합액을 성형틀에 투입하고, 8~24시간 정도 방치하여 경화시켜서 블록형태로 성형하여 반가공블록을 만든다. The paste-like raw material mixture is put into a molding mold, left for 8 to 24 hours to harden, and then molded into a block to make a semi-finished block.
5) 폼화과정5) Formation process
상기 과정에서 만든 반가공블록을 수세하여 반가공블록에 혼합된 기포형성제를 물에 용해시켜서 제거한다. 이와 같이 기포형성제가 물에 용해되어 제거됨에 따라 반가공블록에 마이크로 크기의 오픈 셀(Open Cell)이 형성되어, 반가공블록이 오픈 셀에 의한 3차원 망상구조를 가지는 폼체가 된다.The semi-finished block made in the above process is washed with water to dissolve and remove the bubble forming agent mixed in the semi-finished block with water. As the bubble forming agent is dissolved and removed in water, micro-sized open cells are formed in the semi-finished block, and the semi-finished block becomes a foam body having a three-dimensional network structure by the open cells.
6) 건조과정6) Drying process
상기 폼화과정에서 3차원 망상구조로 폼화된 블록을 100℃ 정도의 열풍건조기에서 건조시켜서, 블록의 기공에 잔존하는 수분을 제거한다. In the forming process, the block formed into a three-dimensional network structure is dried in a hot air dryer at about 100 ° C to remove moisture remaining in the pores of the block.
7) 숙성과정7) Aging process
건조시킨 블록을 70~80℃에서 24시간 방치하여 숙성시킨다. 이러한 숙성과정을 통해 블록의 인장강도, 신장율과 같은 기계적 물성이 향상된다. The dried block is aged at 70 ~ 80 ℃ for 24 hours. Through this aging process, mechanical properties such as tensile strength and elongation of the block are improved.
8) 절단과정8) Cutting process
숙성시킨 블록의 표면을 절삭하고, 원하는 두께로 슬라이스하여 마이크로 필터를 완성한다.The surface of the aged block is cut and sliced to a desired thickness to complete the microfilter.
이와 같은 방법으로 제조되는 마이크로 필터는 마스크용 필터는 물론이고, 다양한 에어필터로 사용되는데, 수용성 수지로서 생분해성을 가지는 폴리비닐알코올과 더불어 디메틸술폭사이드, 커들란, 약산, 아니스알데하이드 등의 인체에 무해한 성분들을 사용하여 제조되기 때문에 인체에 무해하고 생분해성도 가지므로 환경친화적인 장점을 가진다. 또한, 커들란이 사용되어 내구성이 좋고, 오픈셀에 의한 3차원 망상구조를 가지므로 미세먼지의 필터효과도 우수하다. The microfilter manufactured in this way is used as a mask filter as well as various air filters. As a water-soluble resin, biodegradable polyvinyl alcohol, as well as dimethyl sulfoxide, curdlan, weak acid, anisaldehyde, etc. Since it is manufactured using harmless ingredients, it is harmless to the human body and has biodegradability, so it has the advantage of being environmentally friendly. In addition, since curdlan is used, the durability is good, and the fine dust filtering effect is excellent because it has a three-dimensional network structure by open cells.
