[0053] Retaining portion 16 may be any size or shape that aids in releasably retaining object 20 to belt 10. For example, and as illustrated in FIGS. 1-4, retaining portion 16 may be in the form of an extended arm portion in the general shape of a "Lazy S" that may be attached to base plate 11 at one end, and positionable to extend over the object 20 at the other end. Retaining portion 16 may include an indented saddle portion 19 that may be shaped to receive, and be in a mating configuration with, the outer surface of the elongate portion 21 of object 20 to assist in releasably retaining object 20 to belt 10. Although the saddle portion 19 may be any shape or configuration to releasably retain the object 20 to the belt 10, the saddle portion 19 may be a convex arcuate-shaped member for retaining a cylindrically-shaped elongate portion, such as a bolt shaft, as illustrated. To assist in positioning object 20 into retaining engagement with retaining portion 16, retaining portion 16 may further include an upturned portion 17 that acts to lift retaining portion 16 from a closed position to an open position over the outer surface of object 20, as described in detail below. Retaining portion 16 may be formed of any material suitable for releasably retaining object 20 to belt 10. Typically, retaining portion 16 is formed of a material that is compatible with the material that forms retaining member 12. In certain embodiments of the present invention, retaining portion 16 is formed of a flexible corrosion-resistant conductive material, such as aluminum or stainless steel. Although the retaining portion 16 may be any suitable thickness, when retaining portion 16 is formed of stainless steel, retaining portion 16 may be 0.50 to 0.70 mm thick. [0054] In another embodiment of the present invention illustrated in
[0081] Non-limiting examples of anionic electrodepositable coating compositions include those comprising an ungelled, water-dispersible electrodepositable anionic film-forming resin. Examples of film-forming resins suitable for use in anionic electrodeposition coating compositions are base- solubilized, carboxylic acid containing polymers, such as the reaction product or adduct of a drying oil or semi-drying fatty acid ester with a dicarboxylic acid or anhydride; and the reaction product of a fatty acid ester, unsaturated acid or anhydride and any additional unsaturated modifying materials which are further reacted with polyol. Also suitable are the at least partially neutralized interpolymers of hydroxy-alkyl esters of unsaturated carboxylic acids, unsaturated carboxylic acid and at least one other ethylenically unsaturated monomer. Yet another suitable electrodepositable anionic resin comprises an alkyd-aminoplast vehicle, i.e., a vehicle containing an alkyd resin and an amine-aldehyde resin. Yet another anionic electrodepositable resin composition comprises mixed esters of a resinous polyol. These compositions are described in detail in U.S. Pat. No. 3,749,657 at col. 9, lines 1 to 75 and col. 10, lines 1 to 13. Other acid functional polymers can also be used such as phosphatized polyepoxide or phosphatized acrylic polymers as are well known to those skilled in the art.
[0085] Usually, the above-described salt group-containing resins described above are used in combination with a blocked isocyanate curing agent. The isocyanate can be fully blocked as described in the aforementioned U.S. Patent No. 3,984,299 or the isocyanate can be partially blocked and reacted with the resin backbone such as is described in U.S. Patent No. 3,947,338.
[00106] Also, as used herein, the term "cure" as used in connection with a composition, e.g., "a cured composition," shall mean that any crosslinkable or co-reactive components of the composition are at least partially crosslinked or co-reacted. In certain embodiments of the present invention, the crosslink density of the crosslinkable components, i.e., the degree of crosslinking, ranges from 5% to 100% of complete crosslinking. In other embodiments, the crosslink density ranges from 35% to 85% of full crosslinking. In other embodiments, the crosslink density ranges from 50% to 85% of full crosslinking. One skilled in the art will understand that the presence and degree of crosslinking, i.e., the crosslink density, can be determined by a variety of methods, such as dynamic mechanical thermal analysis (DMTA) using a Polymer Laboratories MK III DMTA analyzer conducted under nitrogen. This method determines the glass transition temperature and crosslink density of free films of coatings or polymers. These physical properties of a cured material are related to the structure of the crosslinked network.
[00126] Whereas particular embodiments of this invention have been described above for purposes of illustration, it will be evident to those skilled in the art the numerous variations of the details of the present invention may be made without departing from the invention as defined in the appended claims.

[0053]保持部16可为有助于将物品20可释放地保持在传动带10上的任何尺寸或形状。例如,并如图1-4所示,保持部16可为总体形状为“屈伸(Lazy)S”形的伸长臂部形式,其一端可附在底板11上,另一端可设置成延伸在物品20上面。保持部16可包括凹形鞍部19,其形状可接受物品20的细长部21的外表面并与其成配合结构,从而有助于将物品20可释放地保持在传动带10上。虽然鞍部19可为将物品20可释放地保持在传动带10上的任何形状或结构,但是鞍部19还可为凸面弓形件,如图所示,用于保持圆柱形细长部,比如螺栓轴。为了有助于将物品20设置成与保持部16保持接合,保持部16还可包括上翻部17,其作用是将保持部16从闭合位置升高至物品20的外表面之上的打开位置,下面予以详述。保持部16可由适于将物品20可释放地保持在传动带10上的任何材料制成。通常,保持部16由与构成保持件12的材料相兼容的材料制成。在本发明的某些实施例中,保持部16由象铝或不锈钢之类的柔性耐腐蚀导电材料形成。虽然保持部16可为任何合适的厚度,但当保持部16由不锈钢制成时,保持部16的厚度可为0.50至0.70毫米。
[0081]非限制性阴离子电沉积涂料的实例包括那些具有未胶凝的水分散电沉积阴离子成膜型树脂的涂料。适于用在阴离子电沉积涂料中的成膜型树脂的实例是碱增溶的、含羧酸聚合物,比如干性油或半干脂肪酸酯与二羧酸或酐的反应产物或加合物;以及脂肪酸酯、不饱和酸或酐和任何附加的不饱和改性材料进一步与多元醇反应的反应产物。另外适合的还有不饱和羧酸类、不饱和羧酸和至少一种另外的烯基不饱和单体的羟烷基酯的至少部分中和的共聚体。还有另一种合适的电沉积阴离子树脂包括醇酸-氨基塑料载体,即含有醇酸树脂和胺醛树脂的载体。还有另一种阴离子电沉积树脂组分包括树脂多元醇的混合酯。美国专利号3,749,657的第9栏第1~75行和第10栏第1~13行详细描述了这些组合物。也可使用其他的酸功能聚合物,例如本领域技术人员众所周知的磷化处理的聚环氧化物或磷化处理的丙烯酸类聚合物。
[0085]通常,上述含盐基树脂与封存性异氰酸酯(blockedisocyanate)固化剂结合使用。如上面美国专利号3,984,299所述,异氰酸酯可以全部封存,或者异氰酸酯可以部分封存并与如美国专利号3,947,338所述的树脂主链起反应。
[00106]此外,本文所用的术语“固化”,当其与组合物连用时,例如“固化组合物”是指组合物的任何可交联或共反应的组分至少部分交联或共反应过。在本发明的某些实施例中,可交联组分的交联密度,即交联度范围为完全交联的5%~100%。在其他的实施例中,交联密度范围为完全交联的35%~85%。在另外的实施例中,交联密度范围为完全交联的50%~85%。本领域的技术人员将会理解,可用多种方法测定交联存在度和交联度,即交联密度,比如使用在氮气条件下进行的聚合物实验室MK III DMTA分析器的动态力学热分析(DMTA)方法。该方法测定涂层或聚合物的非支撑膜的玻璃化转变温度和交联密度。固化材料的这些物理性能与交联网络的结构有关。
[00126]尽管上面为了举例说明描述了本发明的具体实施例,但很明显,在不背离附属权利要求书所限定的发明内容前提下,本领域的技术人员可对本发明的细节作各种改变。
