Abstract

The invention provides a powdery coating. The powdery coating is characterized by comprising the following compositions in parts by mass: 25-30 parts of epoxy resin, 25-30 parts of weather-resistant resin, 25-35 parts of modified resin, 1.5-2 parts of high-heat-conducting agent, 5-15 parts of curing agent, 5-10 parts of filler and 3-5 parts of pigment; and in addition, the invention further provides a production technology of the powdery coating. The production technology comprises the following steps: a stirring process: stirring through material mixing equipment so as to fully mix the raw materials; feeding the raw materials into an extruder and melt-extruding; and crushing and tableting and grinding into powder, and mixing in a high-speed mixer. The heat-radiating mechanism of the powdery coating and the effect of spraying the powdery coating onto metal can be improved, the corrosion resistance performance can also be improved, and the powdery coating can be widely applied onto automobile industry, especially on an engine. The powdery coating is simple in formula, convenient to operate, and beneficial to production, so that the production efficiency is improved, the production cost is lowered, and the environment pollution is reduced.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a heat-dissipating powder coating and a preparation process thereof. Background technique [0002] Powder coating is a new type of solvent-free, pure solid powder coating composed of polymers, pigments and additives; it has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. Powder coatings have a high usage rate because they do not emit volatile organic compounds. In the past 10 years, the development speed of powder coatings in the world has been very fast, with an average annual growth rate of 8%-15%. However, the current powder coating still has the defects that the combination of the coating and the metal texture is not as clear as that of the paint, and the heat dissipation of the powder coating is not good enough, so it cannot be widely used in special equipment such as engines. C...
