Traditional powder coating application faces the complicated work piece product of different shapes, and the defect problem of the powder coating inequality exposes more obviously, and simultaneously to the dead angle powder coating not enough, the defective percentage of product improves thereupon, and high energy consumption and dust pollution in the spraying process influence constructor's health greatly. Therefore, the improvement of the overall utilization rate of the powder coating and the improvement of the dead-angle powdering effect become the technical pursuits of the powder coating industry.
At present, an electrical intensifier or an antistatic agent is mostly used in the industry to improve the charging capability of the powder coating, so that the powder coating efficiency is improved. The conductive assistant is added in a proper amount in the formula, so that the powder particles can carry more charges, and the powder particles with more charges can reach the surface of a workpiece by the self-force to improve the powdering of the parts. However, the powder-coating promotion principle cannot overcome the Faraday cage, even strengthen the Faraday cage, and cannot fundamentally solve the problem of uniform powder coating. The antistatic agent product utilizes the water absorption and conductivity effects of the quaternary ammonium salt, so that the heat stability is poor (the quaternary ammonium salt can be decomposed at high temperature), the water absorption and conductivity principle of the antistatic agent is influenced by the humidity of the actual environment, and the caking problem of the coating is easily caused. Therefore, it is difficult to practically use the antistatic agent product to achieve the desired effect.
In fact, organic powdering promoting materials have difficulty in fundamentally solving the problem of powdering of powder coatings due to inherent thermal stability and glass transition temperature, among other problems. The inorganic powdering promoting material plays a role of a wire in the charging and discharging processes of powder particles, improves the dielectric constant of the powder coating, reduces the resistivity of the powder, enables the charge quantity of the powder with different particle sizes to tend to be average, and achieves a good electrostatic powdering effect, so the inorganic powdering promoting material becomes a scheme for well solving the problems of uneven powdering and insufficient powdering at dead angles of the powder coating.
