tribological properties of the significance of
Cathodic electrophoretic coating with the expansion of the scope of application of cathodic electrophoretic paint coating requirements have become more sophisticated, not only the requirements as a primer, and finish requirements as: not only requires good corrosion resistance coating, at the same time excellent wear resistance coating requirements; and so on. Therefore, the development of new functional cathodic electrophoretic coating of industrial coating technology direction efforts. Targeted the improvement of tribological performance as the development of cathodic electrophoretic coating technology, an important study.
In today's social development, industrial development in the mainstream, and in industrial development, related equipment and products plays a crucial role. These equipment and products in the production and application of the process will inevitably suffer from a variety of corrosive chemicals, and some parts of the wear and tear, to the protection and maintenance of equipment, as well as the appearance of product and service life have brought a lot of questions, if a single material from equipment and products to solve the problem, not the economy [14]. The surface coating material is an excellent solution to this problem one way, through the development of a certain characteristics of the paint and coating aids in advanced technology products and equipment related to coating, the corrosion-resistant surface at the same time improve by Moreton resistance, and enhance the service life will be very meaningful. For example, offshore platforms link with fastening bolts. The marine environment in order to prevent the corrosive effect of the strong, the need for painting to protect the bolt, but, as the bolts need to demolish, cause wear and tear on the coating. Because, as with the parts, bolts, there are strict requirements for dimensional accuracy, can only be used on bolt plating or chemical plating process Preparation of surface protection coatings. Therefore, the cathodic electrophoretic coating process to become one of choice. However, the wider application of cathodic electrophoretic coating of epoxy and acrylic cathodic electrophoretic coating wear resistance are difficult to meet the requirements of actual use. Therefore, the need to study and modification of the current rapid development of the most cathodic electrophoretic coating corrosion resistance, wear resistance to enhance its friction-reducing, and ultimately to improve the working environment in the marine bolt the use of performance and reliability. Over the years of study of cathodic electrophoretic coating and more focused on how to improve its corrosion resistance, weatherability, as well as decorative and so on. However, with the cathodic electrophoretic coating expanding the scope of application of the coating should have excellent wear-resistance requirements of anti-friction also increased. Research and analysis indicate that, worldwide, there are about 1 / 2 ~ 1 / 3 in various forms of energy loss in friction, the approximately 80% of the failure of parts in all its forms as a result of wear and tear caused by the repair and replacement of worn-out parts of the cost is amazing. Therefore, to reduce friction and wear has become the conservation of energy, raw materials and maintenance costs of major initiatives, while also improving product quality and accuracy to maintain and extend the service life and improve the reliability of key measures. Cathodic electrophoretic coating to the coating of advanced technology related to the friction pair in order to reduce the friction and wear, so that cathodic electrophoretic coating applications in the machinery to further expand the scope of an innovation will be.
Cathodic electrophoretic coating to enhance the wear-resistant anti-friction performance, one way is to develop a new synthesis of cathodic electrophoretic coating, the resin matrix itself, excellent anti-friction wear-resistance, and the other way on the existing cathodic electrophoretic coating for deep-seated excavation, that is by chemical or physical change in the method of the tribological properties of coatings to meet the use requirements, that is, modified composite electrophoretic coatings. For example, add the graphite phase disulfide, PTFE, such as inorganic or organic filler. In general, than the synthesis of modified coating of paint, a new easier and low cost, quick results. Modification of the physical modification of the implementation of relatively simple, can easily meet the needs and improving the performance requirements of the different materials, are already in other types of solvent-based paints in particular, is widely used in paint.
