Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences Scientists of Ningbo Key Laboratory of Marine Protective Materials and Engineering Technology successfully prepared various types of modified powder coatings, and recently obtained national invention patent authorization.
The patent provides a preparation method and technology for a high-temperature, anti-pollution epoxy resin powder coating.
Compared with the prior art, the fluorosilicon-modified epoxy resin powder coating improves the high temperature and anti-pollution performance of the coating, and can be used in environments up to 500Â°C. In addition, the coating preparation process is simple, the cost is low, and the appearance of the coating is bright, smooth and thin.
It is understood that ordinary epoxy powder coating due to electrostatic effects, easy to be dirt, oil pollution, affecting the decorative coating.
In addition, under the high temperature conditions, this coating has the problems of discoloration and peeling of the coating and the coating is thick, which is subject to certain limitations in the corresponding coating technology field. Fluorocarbon coatings and silicone coating coatings have a very low surface energy and good anti-fouling properties, but these two coatings are relatively expensive.
Therefore, the use of fluorocarbon coating and silicone coating with low surface energy and anti-pollution characteristics to modify the epoxy powder coating can obtain a high temperature, anti-pollution epoxy powder coating.
There are two main production processes. The first type micro-prism-type body reflective logo, mainly using a high-quality, durable micro-prism structure of the reflective material. The structure for the reflecting marking quality requirements of the demanding high reflectivity, its pure, bright color to improve the significance of the day marked.
The second process is made of sealed capsule type reflective material, the width for the logo is 50mm, the surface color is white (150mm).Red interval. In which, white is reflective material natural color, red ink printed on the surface film by silk-screen printing.The surface of the material has a regular hexagonal embossed reflective material structure. Including transparent surface film, air film, glass beads, support layer, resin layer, gum and paper.
