Xingshun provides a brief analysis of the main components in plastic powder
What is plastic powder? This is a common spray coating material in daily life, which not only reduces environmental pollution and saves resources, but also has the characteristic of recycling and is widely used in various industries. So what are the main components in this high-quality plastic powder? Now let Xingshun New Materials give you a brief analysis.
1. Anti corrosion plastic powder; At present, this type of coating is mainly epoxy phenolic anti-corrosion powder coating, which uses epoxy resin and phenolic resin as film-forming substances and crosslinks the two to form a coating. Plastic powder manufacturers believe that the epoxy resin used in this coating typically has molecular weights of 1400 and 2900. Epoxy resin itself has adhesion, flexibility, and good alkali resistance, while phenolic resin has excellent acid resistance, alkali resistance, solvent resistance, heat resistance, moisture resistance, cold resistance, and other properties. These properties are organically combined to become an ideal anti-corrosion material. Due to the weak reactivity between epoxy resin and phenolic resin, the film formation and curing temperature of the coating should be carried out under higher conditions. Adding imidazole catalyst appropriately can lower the curing temperature.
2. Functional plastic powder; Functional plastic powder coating is a surface coating with special functions and applications. It not only plays a traditional protective and decorative role, but also endows materials with various special functions, mainly including insulation, conductivity, anti fouling, heat resistance, flame retardancy, radiation resistance, and other functions. The development and production of functional plastic powder coatings in China have just begun. For example, there is still a significant gap between the products produced by Xinxiang Zhuolong Company and the advanced level abroad.
3. Heat resistant plastic powder; Heat resistant powder coating refers to a powder coating that can withstand temperatures above 200 ℃ for a long time, has a good coating, and can enable the protected object to work normally in high temperature environments. According to the mechanism of polymer thermal stability, the heat resistance of polymers mainly depends on their molecular structure. Therefore, by introducing larger or more polar side groups into the main chain, the intermolecular interaction force increases, thereby improving the thermal stability of the polymer. Another method to improve the heat resistance of powder coatings is to add heat-resistant pigments and fillers to the polymer. Common pigments and fillers include aluminum powder, mica powder, stainless steel powder, cadmium powder, silicon dioxide, etc.
The above three are common components in plastic powder, and the editor has analyzed them from different uses, hoping to be helpful to everyone.
