Notes on the lection of adhesive tapes Apart from the characteristics of the bonding system, the properties of an adhesive bond are also determined by the material composition (e.g., plasticizer content), geometry, weight, as well as by the mechanical behavior (e.g., elasticity, inherent stiffness, dimensions) of the add-on part. Heavy add-on parts of high inherent stiffness and without additional fasteners are not suitable for being bonded using pressure-nsitive adhesives only.The requirements apply to systems that are not subject to dynamic loads. As regards bonded add-
on parts with more stringent mechanical requirements, new values for the adhesive bond must be
specified in the drawing.
The physical/chemical surface condition of the various paint systems is an additional factor of vital i
mportance. A minimum surface energy of (36 to 40) mN/m with a minimum polar fraction of (3,6 to 4) mN/m has been determined empirically for the surface to be bonded. Low-energy surfaces such as tho of PP and TPV > EPDM+PP < are not suitable for adhesive bonds using standard acrylate adhesives. In this ca, the surfaces are either to be pre-treated or specifically modified adhesives are to be ud. If tolerances need to be compensated, it may prove necessary to u a softer adhesive tape. Although this will result in lower strength values obtained in the tensile shear test, it will, at the same time, yield a larger joining surface that can be obtained in a more process-reliable manner. Softer foam cores/foam systems may be ud in this ca. The lower tensile shear strength as per Table 2 required in this ca must be specified in the drawing.The parameters must be taken into consideration when lecting an adhesive tape design. Ex‐
aminations for validating the parameters are obligatory.Dimensions of the adhesive tape Width and thickness: as per drawing.
Design requirements for the process-reliable and functionally reliable u of adhesive
tapes The contours of the bonding surfaces must only exhibit a slight change in the curvature radius. The add-on parts must furthermore feature plane contact surfaces corresponding to the body surfac
es they are to be bonded to. Edges and tight radii are to be avoided in order to prevent peak stress when bonding add-on parts to the body.Joints and bonding gaps must be designed to allow the adhesive tape to be compresd to a specific本拉登死亡
thickness when applying the defined contact pressure. Example: It must be possible to compress an adhesive tape with a thickness of 0,8 mm to at least 50% of its thickness. Specifications concerning
the contact pressure of the adhesive tape (in N/cm 2) and the holding time (in conds) are to be
obtained from the data sheets. The specifications must be verified on the component using suitable
measuring technology (TekScan). An adhesive bond covering the entire surface area is to be aimed
for. Bonding on ribs will result in decread adhesive strength compared to an adhesive bond covering
an entire surface. Embosd areas and swages frequently feature higher tolerances than other con‐
tact surfaces that have to be taken into consideration in the design.
In order to ensure reliable installation, the add-on parts are to feature positioning aids.
When designing components, care must be taken to ensure that the installation of the add-on parts
does not result in plastic deformation of the body or the add-on parts themlves.The lection of the adhesive tape must be part of component design.Paint dependency must be taken into consideration when lecting the adhesive tape. This includes,

挑选胶带的注意事项
除了粘接系统本身的特点之外，胶带粘性还取决于材料成分（如增塑剂含量），几何形状，重量和粘附产品的机械性能（如弹性，固有钢性，尺寸）。钢性大，无固定附件且重量大的产品不适合用压敏性的胶带进行粘附。这些要求适用于不受动态加载影响的系统。如果粘附产品机械要求严苛，应在图
纸增加新的胶带数值进行说明。喷漆系统的物理／化学表面状况是一个很重要的附加因素。经验证明，最小摩擦（３．６－４）ｍＮ／ｍ所产生的最小表面能量（３６－４０）ｍＮ／ｍ可以形成表面粘附。标准丙烯酸酯胶粘剂不a hundred times
pd是什么意思
宜用于粘附低能量表面（如ＰＰ，ＴＰＶ＞ＥＰＤＭ＋ＰＰ＜）。这种情况下，
要么表面进行预处理，要么对胶带进行改良。虽然这会导致在拉伸剪切试验中强度值变小，但同时，它会形成一个更大的接合面。这种情况可以使用较软的泡沫孔／泡沫系统。如Ｔａｂｌｅ ２ 所示，拉伸剪切测试产生的较低的强度值应在图纸中
进行说明。
胶带尺寸宽度和厚度：见图纸挑选胶带设计时应考虑这些参数。必须检查这些参数的有效性。实现胶带可靠工序和可靠功能的设计要求接合面的轮廓仅通过曲率半径稍作更改。粘附产品的平面
接触面的状态必须和将要粘附的车身表面状态一致。粘附过程进行中，应避免出现过紧的边缘半径以防峰值应力的出现。为确保安装，粘附产品需有安装定位。设计时，必须小心确保产品安装不会导致被粘附体变形或产品自身变形。胶带挑选应成为产品设计的一部分。
挑选胶带时应考虑油漆粘附性，包括不同的硬度（颜色，底漆），表面轮廓（微型）。
设计时，应留出间隙使胶带受到触点压力时可压缩到一定厚度。如：把０．８ｍｍ厚的胶带压缩至少５０％一定可以。数据表上可以看到关于胶带触点压力（Ｎ／ｃｍ２）和持续时间（秒）的信息必须用适当的技术（ＴｅｋＳｃａｎ）确认规格书上的各个部分的描述，比如覆盖在整个表面区域的信息。与粘附整个表面相比，粘附在螺纹上会降低粘附强度。和其他接触面相比，凹凸区需要更高的公差要求，设计时应考虑这点。

adhesive tapes applied to uneven surfaces will result in insufficient contact. Improved contact on uneven surfaces can be achieved by using softer adhesive tapes of incread thickness. For critical colors, it may prove necessary to support the adhesive bond (adhesion) through the application of primer or suitable pre-treatment methods.Joining surfaces must be designed to ensure that all of the theoretical bonding surface is utilized.Ribs and honeycomb structures minimize the effective bonding surface and air inclusions will subject the adhesive bond to additional loads when the air expands. Adhesive bonds on ribs may allow humidity to penetrate. Deviations in the geometry of joining partners, particularly at the ends, lead to permanent stress which will cau the bonded add-on parts to deatch from the body. Adhesive bonds in embosd areas and swages are critical with regard to the resulting tolerances (e above).Nameplates must not be undersized (< 0,25 cm 2) be
cau otherwi the adhesive bond will not provide sufficient shear strength to avoid dislocation. The edge ratio should not exceed 2:1 for purely uniaxial geometries.Types –

TL 52018: 2011-03如果胶带用于不平表面，则接触不充分。用较软加厚的胶带可以改善在不平表面的接触。对于特殊颜色，使用底漆或增加前处理来增强粘附性非常有必要。字牌尺寸不能太小（＜０．２５ｃｍ２），否则胶带不能提供足够大的抗剪强度来避免错位。对于单纯的单轴几何，边缘比例不能超过２：１。
当空气膨胀时，空气中的物质会扩大胶带的粘附面积。螺纹上的胶带或许会渗透湿气。粘合个体双方的尺寸偏差，此段译文在最上方接合面设计时必须保证所有理论接合面在实际应用过程中可以使用。螺纹和蜂巢结构使有效粘附表面最小化。如两端，会产生永久应力，此应力会使产品分离脱落。胶带在凹凸区域对定义公差具有重要作用。型号基体为ＰＣＲ泡沫的胶带基体为ＰＵＲ泡沫的胶带基体为ＥＶＡ泡沫的胶带基体为ＰＥ的胶带闭孔泡沫芯聚丙烯酸酯胶带
