Description

一种电热膜的制备方法技术领域本发明属于电热材料的制备方法,特别涉及一种电热膜的制备方法。 TECHNICAL FIELD The present invention is one kind of electric film production method belongs electric material, in particular relates to a method for preparing the electric heating film. 背景技术在使用电热涂层材料通过丝网印刷制造高分子电热膜(片,板)时,在制备过程中经常会遇到几个困难。 BACKGROUND ART When producing a polymer electric film (sheet, plate) by screen printing using a hot coating material in the manufacturing process often encounter several difficulties. 其一是如何根据产品的技术要求(电阻,轮廓尺寸和接电位置),设计导电网络图;其二是如何根据所使用的电热涂层材料的技术参数(方块电阻或称方阻)来规范设计与制造工艺,印制电热涂层。 One is how the technical requirements (resistance, electrical connection position and size of the profile), FIG conductive network design; second is how to regulate the electric parameters of the coating material according to the technique to be used (known as sheet resistance or sheet resistance) design and manufacturing process, the printed electric coating. 其三是如何面对巿电(220-230伏) 的高电压带来的困扰。 The third is how to deal with troubled market power (220-230 volts) of high voltage brings. 相当长一段时间还没有摆脱使用电源变压器的需要,这一点给新产品的研发和生产带来了很大的限制。 Quite a long time not out of need to use the power transformer, which brings a lot of restrictions to new product development and production. 首先是设计过程的盲目性。 The first is the blindness of the design process. 在实际实施过程中,较好处理的是根据产品要求的轮廓尺寸和接电位置进行设计。 In the actual implementation process, the process is preferably designed according to the size and contour location required by the electrical connection. 而对于产品电阻的要求则只能依靠多次试验来接近所要求的技术指标,设计的盲目性很大。 As for the resistance of the product requirements can only rely on several tests to be close to the required technical specifications, a great design of blindness. 其次是制造过程的盲目性。 Followed by blindness manufacturing process. 这种盲目性源于理性设计对实际制造的偏离,源于对电热涂层材料的认识不足。 This stems from the rational design of blindness from the actual manufacturing, due to lack of understanding of electric coating material. 如果是使用自配的电热涂层材料则是通过增减导电组份, 一次次地调整配方来满足产品的技术要求。 If you are using the coating material from the distribution of heating is set by increasing or decreasing the conductive parts, a time to adjust the formula to meet technical requirements. 在使用从市场采购的电热涂层材料时,其技术指标只不过用作采购时的参考。 When using electric coating material from market purchases of its technical indicators only used as a reference when purchasing. 还做不到用电热涂层材料的技术指标来引领设计与制造工作。 Specifications also do with heating of the coating material to guide the design and manufacturing. 在人们使用低电压发热产品的同时,早就想把在低压电源上用得很好的电热产品推广用在自已的日常生活中。 While people use low voltage heating products, has long wanted to use in low-voltage power supply used to promote the well-electric products in their own daily lives. 可是要从低电压转变到高电压,从安全电压转变到市电(220-230伏)不是一个顺利和方便的过程。 But the transition from a low voltage to high voltage transition from safety to mains voltage (220-230 V) is not a smooth and easy process. 至少必须配备一个沉甸甸的电源变压器, 极不方便,又费钱。 It must be equipped with at least a heavy power transformer, very inconvenient, and expensive. 这就阻碍了高分子电热膜(片、板)技术在更大范围内推广应用, 阻碍了人们实现自己的合理需求与良好愿望。 This hindered the polymer electric membrane (sheets, plates) promote the use of technology on a larger scale, discouraging people to achieve their legitimate needs and good wishes. 发明内容本发明的目的是提供利用电热涂层材料的方阻和根据目标产品的外部特性和内部特性来制备电热膜(原片,即未安装接电极的电热膜加热片)的方法。 Object of the present invention to provide a method for preparing and sheet resistance heating film (original film, i.e. the film electric heater chip bonding electrode is not installed) based on the external and internal characteristics of the use of electric characteristics of a target product coating material. 本发明推荐一种电热膜的制备方法,它包括以下若干步骤-1、 确定执行目标或需要完成任务的技术指标及其数量。 The present invention proposes a method of preparing electric film, which comprises a plurality of Step-1, or determines to perform certain specifications and quantity required to complete the task. 在本项目中,它们是目标产品的参考电阻和工作电压。 In this project, which is the reference resistance and the operating voltage of the target product. 用1=11/11#算出该产品的起始(工作)电流1。2、 根据用于目标产品的电热涂层材料的方阻和该产品的工作电压,用IU/R力算出方块电热膜的起始(工作)电流r。 With 11 = 1/11 # calculates start (operation) of the current product 1.2, in accordance with an electric sheet resistance of the coating material for the target product and the operating voltage of the product, with IU / R force calculation block electric film starting (operating) current r. 3、 计算目标产品需用方块电热膜的数量n, n=I/I',并以此作为设计目标产品的基准。 3, calculates the target product of the number n of required electric film squares, n = I / I ', and designed as a reference product. 4、 在目标产品的轮廓尺寸范围内布置接电位置;从接电两极各引出一条导电线路,彼此之间相互平行交错,好似相互穿插的两把发梳,购成导电网络;其中导电线路的长度为w,导电线路的间距为L, (1)当L〉w, n=L/w, (l)当L<w, n=w/L;完成电脑平面设计,发出菲林片供制版用。 4, is arranged within the contour of the product size range of the target position of the electrical connection; bipolar electrical connection from each one conductive lead line, staggered parallel to each other, like the two interpenetrating comb, available as a conductive network; wherein the conductive trace length w, pitch of the conductive lines is L, (1) when L> w, n = L / w, (l) when L <w, n = w / L; completed computer graphic design, issued film sheet for plate making . 5、 在目标产品的轮廓尺寸范围内填充代表电热涂层材料的黑色,完成电脑平面设计, 发出菲林片供制版用。 5, in the size range of the target profile representing black product filled heating the coating material, is completed computer graphic design, issued film sheet for plate-making. 注意尺寸递减,目标产品略小于伴热对象,导电网络略小于目标产品,电热涂层的填充范围略小于导电网络。 Note that decreasing the size of the target heating object is slightly smaller than the product, the conductive network is slightly smaller than the target products, the range is filled electric conductive coating is slightly smaller than the network. 6、 在丝网印刷机上,以高性能耐热膜(片、板)为基底,用导电银浆印制第4款设计的导电线路(网络),并进行热处理。 6, in the screen printing machine, high-performance heat-resistant film (sheets, plates) of the base, the design printed conductive traces, paragraph 4 (network) with conductive silver paste, and heat-treated. 7、 在丝网印刷机上,以第6款产生的银浆片为基底,用电热涂层材料印制第5款设计的电热涂层,并进行热处理。 7, in the screen printing machine to produce paste sheet paragraph 6 of the substrate, the printed paragraph 5 with electric heating coating design of the coating material, and heat-treated. 8、 测定第7款试制过程中得到的试产品,与第l款确定的技术指标相比较。 8, paragraph 7, a measurement sample product obtained in the trial process, and determining the specifications of paragraph l compared. 如果彼此不符合,则回到第4, 5款修改设计,适当调整需用方块电热膜的数量(n),重复第6、 7款的制备过程,直到测定技术参数符合第1款确定的技术指标。 If you do not coincide with each other, the process returns, 5, paragraph 4, to modify the design, appropriate adjustments to the number (n) required square electric film, the sixth repeat the preparation process of paragraph 7, until the determined measurement technical parameters meet technical paragraph 1 index. 上述技术步骤突出了技术理念中的一个关键。 Technical steps above highlights a key concept in technology. 核心的问题是如何认识和用好构成电热膜的电热涂层材料及其方阻。 The core problem is how to understand and use electric heating film constituting the coating material is good and sheet resistance. 通常导电涂料的用户中,制造印刷线路板者关心的是导电。 Users typically conductive coating, the printed circuit board manufacturing concern who is conducting. 而导电对导电材料是不存在认识,设计和使用的困难的。 The conductive conductive material is not present understanding, design and use of difficult. 制造电热产品者关心的是导电后的生热。 Manufacture of electric products were concerned about the heat conductivity. 而要掌握电热转换就不能不更多的熟悉电热涂层材料及其方阻。 The electric conversion can not fail to grasp more familiar with electric coating material and sheet resistance. 但是,对电热涂层材料及其方阻的认识不足,以及不具备测试电热涂层材料方阻的条件则增加了这一方面的困难。 However, lack of knowledge of the electric resistance of the coating material and square, and do not have the conditions to test electric sheet resistance of the coating material increases the difficulty in this regard. 而本发明正是合理而有效的利用了电热涂层材料的这一重要的方块电阻或称方阻的这一物理特性。 And the present invention is reasonable and effective use of this important electric sheet resistance of the coating material or the physical characteristics of said side hindrance. 方块电阻或称方阻是从半导体物理借用过来的。 Said sheet resistance or sheet resistance is borrowed from semiconductor physics over. 在分析PN结薄层的物理性质时对于矩形截面给出其电阻R值为:R=px L/ (w xS)其中:P为材料电阻率;L, w, S分别为材料的长,宽和厚度。 When analyzing physical properties are given PN junction thin rectangular cross-section with respect to the resistance value of R: R = px L / (w xS) where: P is the material resistivity; L, w, S material are long, wide and thickness. 整理上式: R= ( P/S ) x (L/w )当材料的长度与宽度相等时,S卩:L = W。 On finishing the formula: R = (P / S) x (L / w) equal to the length when the width of the material, S Jie: L = W. 则有:R= (P/S )。 There are: R = (P / S). 此时R- (p/S )即R (方阻)二(P/S),则有材料电阻Rn (P/S )。 At this R- (p / S) i.e. R (square resistance) bis (P / S), the resistance of the material has Rn (P / S). 请注意,这里并没有限定L或w的大小。 Note that there is not defined or the size L of w. 这是一套普通而又简洁的技术方案。 This is a common and simple technical solutions. 好处是克服了上述若干困难,通过增减n的数量,可以使用不同方阻的电热涂层材料;通过增减n的数量,可以方便地把工作电压从低电压扩展到高电压;同时又在使用中彻底抛弃了沉甸甸的电源变压器。 Several benefits are overcome these difficulties, by increasing or decreasing the number of n, different materials may be used electric sheet resistance of the coating; by increasing or decreasing the number of n, the operating voltage can be easily expanded from a low voltage to a high voltage; at the same time completely abandoned the use of heavy power transformer. 这一切将为促进新兴电热膜(片,板)产业的快速发展扫清障碍。 All this will contribute to promoting the emerging electric film (sheets, plates) rapid development of the industry to pave the way. 具体实施方式实施例1汽车后视镜加热膜原片的制备方法,首先确定汽车后视镜加热膜片的参考电阻和工作电压分别是8欧姆和12伏特,所用电热涂层材料的方阻是6千欧。 Example 1 Rearview Mirror DETAILED DESCRIPTION Embodiments of film production method of the original sheet is heated, the diaphragm is first determined automotive mirror heating and the operating voltage of the reference resistor are 8 ohms and 12 volts, the electric sheet resistance of the coating material used is 6 kilohms. 据此算出目标产品的起始(工作)电流是1.5安培,方块电热膜的起始(工作)电流是2毫安。 Accordingly start calculating the target product (work) current is 1.5 amps, the starting (working) block electric current is 2 mA film. 根据上面两个电流数据算出方块电热膜的数量n=750。 The two above the current block of data calculates the number of electric film n = 750. 以此为基础,在目标产品的轮廓尺寸内布置接电位置,从接电两极各引出一条导电线路,彼此之间相互平行交错,好似相互穿插的两把发梳,购成导电网络。 On this basis, the position of electrical connection disposed within the outline size of the target product, a conductive trace from each of the lead poles electrically connected parallel to each other cross each other, like the two interpenetrating comb, available as a conductive network. 取L-2mm, w=1500mm,即是r^WL-750。 Taking L-2mm, w = 1500mm, that is, r ^ WL-750. 完成导电线路和电热涂层的设计并输出菲林片制版。 And an electric conductive coating to complete the circuit design and output film sheet plate. 在聚酯膜上经丝网印刷和12(TC热处理20分钟,先后完成导电线路和电热涂层的制作,再经测试和反复调试,得到所需要的汽车后视镜加热膜原片。 实施例2电热保暖鞋电热膜原片制备方法,首先确定电热保暖鞋电热膜片参考电阻和工作电压分别是8千欧和220伏特,所用电热涂层材料的方阻是20千欧。据此算出目标产品的起始(工作)电流是27.5毫安,方块电热膜的起始(工作)电流是11毫安。根据上面两个电流数据算出方块电热膜的数量11=2.5。以此为基础,在矩形基底上布置两条彼此之间相互平行的导电线路。取1^60mm, w=150mm,即是『w/L-2.5。完成导电线路和电热涂层的设计并输出菲林片制版。在聚酯膜上经丝网印刷和12(TC热处理20分钟, 先后完成导电线路和电热涂层的制作,再经测试和反复调试,得到所需要的电热保暖鞋电热膜原片。 In the polyester film by screen printing and 12 (TC heat treatment for 20 minutes to complete the production has conductive traces and heating the coating, and then tested and repeated testing, to obtain a film original sheet automotive mirror heating required.
