With the rapid development of color coating industry, the development of high performance paint color plates and high-class products to meet the diverse needs, has become a hot research at home and abroad. Preparation which has good adhesion and flexibility, as well as essential and good matching of the primer paint color coated coil offer to improve the performance of the paint color plates. As the domestic coil coatings in the variety and quality are behind the foreign products, resulting in the production of our manufacturers color plates painted volumes, had to use expensive imported paint, which greatly affect the development of China's color board industry. Due to many factors, the preparation of the primer is a complex process. Recently researchers have been using domestic orthogonal experiment to determine the impact of various factors on the performance of epoxy primer, thus using less reasonable steps to determine the best formula, the prepared film has obvious hardness and solvent resistance advantages, but also excellent adhesion properties. According to the China Association of epoxy resin industry experts, the price of color coated paper, they focus on the chosen pigment to binder ratios, crosslinking agent, catalysts, defoamers, reducing surfactant additives, wetting dispersant six kinds of factors. Select the crosslinking agent is a urea-formaldehyde resin SM-526, proved: Adhesion affect crosslinking curing agent for the film's biggest, but also have a greater impact and resistance to MEK wipe bending performance, no significant effect on the film hardness. The new color-coated roll coater coating machine is the key equipment roll coating process, a higher yield using two sets of multi-color coating unit fine coater to shorten the replacement of paint and coating roller cause downtime. Has developed a new coating machine: Features a double-coated fine coater head, that volume is arranged under two painted lime painted head, hydraulic drive to replace the coating roll, about 2 seconds to complete the color change, it covers small; single slide coating machine, which eliminates the gap between the rolls of multiple errors piled higher than the traditional type slide coating machine precision coating, the coating thickness can implement the best control, can save a lot of paint. Some roll coater also added Dr. knife used in the production of high quality color coated.
