[0041] 膨体聚四氟乙烯微孔薄膜材料简称“ePTFE膜”,“ePTFE”是膨体聚四氟乙烯英文单词(expanded polytetrafluorethylene)的缩写;膨体聚四氟乙稀微孔薄膜是一种具有特殊功能高附加值的高分子新材料薄膜,是经特殊工艺经双向拉伸制成的,该薄膜的微纤维构成了里外通透的0.1μπι~18μπι孔径的微孔,是真正意义的透气膜。 [0041] PTFE microporous film material referred to "ePTFE membrane", "ePTFE" English word is expanded polytetrafluoroethylene (expanded polytetrafluorethylene) Abbreviation; expanded PTFE microporous film is a new kinds of polymer material film having a high value-added special function, a special process is made by biaxial stretching, the film microfibers microporous 0.1μπι ~ 18μπι transparent aperture inside and outside, is the true meaning the gas permeable membrane. 膜表面每平方英寸能达到几十亿个微孔,每个微孔直径小于轻雾水珠的最小值(20 μηι~100 μ m),而远大于水蒸气分子直径(0.0003 μ m~0.0004 μ m),可以使水蒸气通过而水滴因表面涨力大不能通过,利用这种微孔结构可达到优秀的防水透湿功能;另外因为该孔极度细小和纵向不规格的弯曲排列,用在汽车电气电子设备防护方面,虽能使得汽车电气电子设备内的空气通过此膜对流调节压力平衡,达到无污染的尘密,但是当汽车停开时没法阻止或减少环境中的水蒸气进入壳体内,滞留在壳体内的水蒸气湿度过高将严重影响汽车电气电子设备的性能的发挥。 Membrane surface per square inch can reach billions of pores, each pore diameter smaller than the minimum mist of water droplets (20 μηι ~ 100 μ m), and the water vapor molecules is much larger than the diameter (0.0003 μ m ~ 0.0004 μ m), water vapor may be due to the surface tension of water droplets can not be large, use of such microporous structure can be achieved by excellent water permeable function; further since the aperture is extremely small and not longitudinal bend alignment specifications, used in automotive electrical and electronic equipment protection aspect, although the air in the automobile enables electrical and electronic equipment through the film convection regulating pressure balance, to achieve the dense dust pollution, but not open when the car stops to prevent or reduce water vapor into the environment within the housing residence in high humidity within the housing water vapor will seriously affect the performance of automotive electrical and electronic play device.

[0042] 含有亲水基团的涂层透湿原理:聚氨基甲酸酯乳液涂层中的聚氨基甲酸酯分子结构中含有-NHC00-单元的高分子化合物,其主要原理是在聚合物链上引入适量的亲水基团,在一定条件下自发分散形成乳液,PU大分子中含有大量的极性基团,分子间力很强,致使其具有优良成膜性,能够在织物上形成坚韧而耐久的薄膜,它还具有一定透湿性。 [0042] The principle of the moisture-permeable coating layer containing a hydrophilic group: polyurethane molecular structure of the polyurethane in the emulsion coating containing a polymer compound -NHC00- unit main principle is that in a polymer a suitable amount of hydrophilic group introduced on the chain, under certain conditions, spontaneously form an emulsion dispersion, PU macromolecule containing a large amount of polar groups, a strong intermolecular force, so that it has excellent film forming property, can be formed on the fabric tough and durable film, it has a certain moisture permeability. 其原因是:一方面PU中的极性基团或亲水基团,如-0H、-NHC00-、-C00H和有机硅微粉等的氢键和分子间的作用力,使水蒸气分子沿着阶梯从高湿度一侧迀移到低湿度一侧;从理论上讲,高分子链上主要有亲水基团,且只要亲水基团含量和排列合适,则它们便可以和水分子作用,借助氢键和其它分子间作用力,在高湿度一侧吸附水份后,通过高分子链上亲水基团传递到低湿度一侧解吸。 The reason is: on the one hand PU polar group or a hydrophilic group, such as -0H, -NHC00 -, -, and hydrogen bonding force between the organic molecules and microsilica C00H, so that water vapor molecules along step move from the high humidity side Gan low humidity side; hydrophilic group theory, the main polymer chain, and as long as the content of a hydrophilic group and a suitable arrangement, and they can effect the water molecule, via hydrogen bonding and other intermolecular forces, one side of the adsorption of water in a high humidity, low humidity transmitted to the desorption side through a polymer chain a hydrophilic group. 因此,透湿实质上是一个“吸附-扩散-转移-解吸”的过程。 Thus, moisture is essentially a "Adsorption - Diffusion - Transfer - desorption" process.

[0043] 汽车电气电子设备用持续单向透湿的涂层膜是在膨体聚四氟乙烯微孔薄膜的一侧表面涂覆含有亲水基团聚氨基甲酸酯乳液涂层,经80°C~10(TC温度烘干涂层,室温存放24h后,涂层就固化在膨体聚四氟乙烯微孔薄膜面上,形成一层致密的耐久的涂层,该涂层含有亲水基团,和水分子作用,借助氢键和其它分子间作用力,在高湿度一侧吸附水份后,通过高分子链上亲水基团传递到低湿度一侧解吸。因此,透湿实质上是一个在亲水基团聚氨基甲酸酯涂层表面“吸附”水蒸汽分子-水分子在亲水基团聚氨基甲酸酯涂层内向外侧“扩散水分子在亲水基团聚氨基甲酸酯涂层与膨体聚四氟乙烯微孔薄膜的结合界面面上“解吸水分子进入膨体聚四氟乙烯微孔薄膜密布的微孔向外部环境排出湿气的过程。 [0043] Automotive electrical and electronic device using unidirectional continuous moisture-permeable coating film is coated on one surface of the microporous ePTFE film of the hydrophilic group-containing urethane emulsion coating agglomerates by 80 ° C ~ 10 (TC coating drying temperature, stored at room temperature after 24h, the coating film on the surface of a cured microporous PTFE, durable form a dense coating, the coating containing a hydrophilic group group, and the role of water molecules, by hydrogen bonding and other intermolecular forces, one side of the adsorption of water in a high humidity, low humidity transmitted to the desorption side through a polymer chain hydrophilic groups. Thus, substantially moisture is a surface of the hydrophilic group in the urethane coating reunion "adsorption" water vapor molecules - the water molecules within the hydrophilic groups are polymerized urethane outer coating "diffusion of water molecules in the hydrophilic groups are polymerized urethane coating interfacial bonding layer and the surface of the microporous ePTFE film "desorbing water molecules into dense PTFE microporous film microporous discharging moisture to the outside environment process.
