摘要

We attempted to prepare medium-oil-length glycerol alkyds based on Mahua oil. Fatty acids were isolated from the oil and used in the preparation of alkyds by the fusion method. The resins were characterized by IR spectroscopic analysis. The physicochemical and film properties of these resins were also studied. IR analysis of the resins revealed the formation of phthalate esters showing characteristic peaks at 1720 cm(-1). The resin was modified with melamine formaldehyde, which cured at high temperatures. Alternatively, the resin was made to air dry with ester gum, and the curing behavior was studied. The suitability of these resins for high-temperature curing fly ash coating applications was established. Coatings were formulated with these resins and with 40% fly ash as an extender. The coatings were characterized by standard techniques, particularly for their anticorrosive and antiabrasive properties. Resistance to corrosion was evaluated in humidity and in salt-spray conditions. We conducted a high-stress (two-body) abrasion test to test the abrasive wear resistance of the coatings. The Mahua-oil-resin-based fly ash coatings were suitable for application in moderately corrosive and abrasive environments. (C) 2002 Wiley Periodicals, Inc. [References: 32]
