Effect of Pretreatment on Aluminum Pigment Properties

Aluminum pigment is a kind of grey powder with metallic luster which can be annexed with proper matrix to produce a typical aluminum appearance, thus to change its property, pretreatment is needed. In this paper, author pre-treats aluminum powder with Molybdenum and hydrogen peroxide, and also studies effects of dosage of molybdenum and isopropyl alcohol, reaction time and temperature on aluminum pigment. The research reviews that the most proper pre-treated condition is as following: 0.12g molybdenum, 1.2g hydrogen peroxide, 150g isopropyl alcohol, 60¡æ reaction temperature and 4-hour reaction time. Pre-treated under this condition, the corrosion resistance of aluminum pigment is relevant better, and the luster of which is not much different from untreated aluminum pigment.
  
Key words: Aluminum pigment; Pretreatment; Sol-gel method; Acid and alkali resistance
