"Research on Perfluoropolyether-modified Polyester Powder Coatings" prepared a perfluoropolyether-modified polyester resin powder coating. The coating formed by this coating has good weather resistance, anti-corrosion, hydrophobic and anti-fouling effects. However, the adhesion of this kind of coating is not satisfactory, and the anti-stripping performance is poor. In addition, the friction coefficient of the coating surface is low, and there are safety hazards in use, and the production cost is high, which is not economical, so it needs to be further modified. to obtain products with superior comprehensive performance

The invention discloses a hybrid polyimide modified polyester-nitrile-butadiene rubber composite powder paint. The powder paint has the characteristics that polyester resin and liquid nitrile-butadiene rubber are compounded, thereby effectively improving the shrinkage and cracking phenomena occurring on a coating when hydroxyalkylamide is used as curing agent and enhancing the adhesive force of the coating; the prepared gas-phase aluminum oxide hybrid polyimide precursor is formed into hybrid polyamide resin after hot imidization, thereby remarkably increasing the mechanical property of the paint, reflecting excellent radiation resistance and low-temperature resistance, and achieving favorable powder flowability and lower adhesion possibility; and the coating layer of the paint finally obtained by additionally combining other raw materials is firm, smooth, wear-resistant, environment-friendly and durable, and the use experience and service life in outdoor environment are effectively improved.
Description
technical field [0001] The invention relates to the technical field of outdoor powder coatings, in particular to a hybrid polyimide modified polyester-nitrile rubber composite powder coating and a preparation method thereof. Background technique [0002] With the improvement of living standards, fitness and amusement equipment, as a multifunctional equipment integrating fitness and entertainment, can be seen everywhere in residential areas, squares and other places. Most of the equipment itself is made of metal materials, and the surface is sprayed with paint. Since the fitness and amusement equipment directly contacts the human body, and most of the users are the elderly and children, the environmental protection of the paint is also very important. Water-based paint is an environmentally friendly Coatings with high corrosion resistance have been widely concerned, but water is easy to corrode metal, so it is not suitable for coating on metal materials. In addition, fitness ...
