高吸附性能奈米纖維空氣過濾材及其製法 Nano-fiber air filter material with high adsorption performance and its preparation method

本發明係有關於一種高吸附性能奈米纖維空氣過濾材，特別是涉及吸附性能奈米纖維空氣過濾材及其製法。 The present invention relates to a nanofiber air filter material with high adsorption performance, in particular to a nanofiber air filter material with adsorption performance and a preparation method thereof.

隨著科技發展，空氣汙染及氣候變遷溫室效應日趨嚴重，空氣中的VOCs、PM2.5、粉塵嚴重影響著人們的生活，對人們的身體健康造成很大的威脅。PM2.5的組成複雜，粒徑分佈廣泛，小於2μm的細顆粒物可以深入到人體的細支氣管和肺泡，直接對人體肺功能產生影響。 With the development of science and technology, the greenhouse effect of air pollution and climate change is becoming more and more serious. VOCs, PM2.5, and dust in the air seriously affect people's lives and pose a great threat to people's health. The composition of PM2.5 is complex and the particle size distribution is wide. Fine particles smaller than 2 μm can penetrate deep into the bronchioles and alveoli of the human body and directly affect the lung function of the human body.

VOCs已成為空氣中的一種常見的室內空氣污染源，尤其是游離之甲醛，對人體健康危害甚大，除了濃度過高會引起眼睛與呼吸道極度不過外，甲醛也會引起許多疾病，如呼吸道疾病、新生兒畸形、急性精神抑鬱症，甚至引起呼吸道、皮膚、消化道之癌症等。因此，如何有效降低空氣中的甲醛含量是相當重要的課題。目前，我們對PM2.5的防治大多集中在室外個體防護方面，對室內空氣的淨化關注較少。然而，隨著人們居住條件的提高，家庭裝修普遍化，且為了節約能源，室內通常處於密閉狀態，從而導致室內污染物濃度過高，另外，人們每天有超過80%的時間在室內度過，所以室內空氣品質對我們的健康的影響尤為顯著。 VOCs have become a common source of indoor air pollution in the air, especially free formaldehyde, which is very harmful to human health. In addition to excessive concentration, it can cause extreme eyes and respiratory tracts. Formaldehyde can also cause many diseases, such as respiratory diseases and newborns. Infant deformities, acute depression, and even cancer of the respiratory tract, skin, and digestive tract. Therefore, how to effectively reduce the formaldehyde content in the air is a very important subject. At present, most of our prevention and control of PM2.5 focus on outdoor personal protection, and less attention is paid to indoor air purification. However, with the improvement of people’s living conditions, home decoration has become common, and in order to save energy, indoors are usually Being in an airtight state leads to high indoor pollutant concentrations. In addition, people spend more than 80% of their time indoors every day, so indoor air quality has a particularly significant impact on our health.

目前室內空氣淨化技術主要包括過濾法、吸附法、光催化法、負離子法和植物吸收法。過濾法是最直接有效的過濾空氣中VOCs、PM2.5、粉塵的方法，但普通的空氣過濾材料效率低、阻力高，不能滿足人們對空氣品質的要求，迫切需要開發一種高效率、低壓損的過濾材，並能有效去除空氣中粉塵、甲醛及細菌等空氣污染物的高性能性空氣過濾材料，尤其是高效率空氣過濾材。 At present, indoor air purification technologies mainly include filtration method, adsorption method, photocatalysis method, negative ion method and plant absorption method. The filtration method is the most direct and effective method to filter VOCs, PM2.5 and dust in the air, but ordinary air filter materials have low efficiency and high resistance, which cannot meet people's requirements for air quality. There is an urgent need to develop a high efficiency and low pressure loss method. High-performance air filter materials that can effectively remove air pollutants such as dust, formaldehyde and bacteria in the air, especially high-efficiency air filter materials.

高效率空氣過濾材(High efficiency particulate air，簡稱HEPA)是一種以260nm微粒在5.3cm/sec流速下測試，其過濾效率在99.97%以上、壓損為32mm H₂O以下；若在14cm/sec流速下測試其過濾效率則為94%以上、壓損則為94mmH₂O以下的過濾材料。這種過濾材料可應用在半導體工藝的無塵室或生物無菌室(bio-clean room)的空氣過濾。在上述環境必需使用穩定的HEPA濾網，以避免空氣中微粒損壞無塵室的產品或減少無菌室所含的物質。 High efficiency particulate air (HEPA) is a test with 260nm particles at a flow rate of 5.3cm/sec. The filtration efficiency is above 99.97% and the pressure loss is below 32mm H ₂ O; if it is 14cm/sec When tested at a flow rate, the filtration efficiency is above 94%, and the pressure loss is below 94mmH ₂ O. This filter material can be applied to air filtration in a clean room or a bio-clean room in a semiconductor process. In the above environment, a stable HEPA filter must be used to prevent airborne particles from damaging the products in the clean room or reduce the substances contained in the clean room.

目前市售的HEPA濾材組成主要有玻璃纖維或聚丙烯熔噴不織布，最常見的是玻璃纖維不織布濾材，在折疊加工時較易碎裂；聚丙烯熔噴不織布經靜電處理後，因材質較軟機械強度不高需與其它基材進行折疊加工，這些濾材都具有一定程度的限制，若要達成一定程度的過濾效果(以260nm微粒在5.3cm/sec流速下測試，過濾效率需在99.97%以上、壓損為32mm H2O以下)，其單位面積的重量都會大於70g/m²，且往往有很高的壓損值。 Currently commercially available HEPA filter materials mainly consist of glass fiber or polypropylene melt-blown non-woven fabric, the most common is glass fiber non-woven fabric filter material, which is more likely to break during folding processing; polypropylene melt-blown non-woven fabric is soft after electrostatic treatment The mechanical strength is not high and needs to be folded and processed with other substrates. These filter materials have a certain degree of limitation. To achieve a certain degree of filtration effect (tested with 260nm particles at a flow rate of 5.3cm/sec, the filtration efficiency needs to be above 99.97% , Pressure loss is below 32mm H2O), the weight per unit area will be greater than 70g/m ² , and often have a high pressure loss value.

奈米纖維過濾材料，由於其稀疏多孔的結構和相對較高的比表面積，在眾多過濾材料中性能最為優越。但由於其一般由高聚物紡制而成，大多只能對空氣中的懸浮顆粒進行攔截和靜電吸附，不能除去空氣中的細菌，病毒和有機污染物如VOCs。 Nanofiber filter material, due to its sparse porous structure and relatively high specific surface area, has the most superior performance among many filter materials. But because it is generally made of high polymer spun, most of them can only intercept and electrostatically adsorb suspended particles in the air, and cannot remove bacteria, viruses and organic pollutants such as VOCs in the air.

綜上所述，目前仍需新的高吸附性能奈米纖維空氣過濾材以克服上述問題。 In summary, there is still a need for new high-absorption nanofiber air filter materials to overcome the above-mentioned problems.
