High-efficiency modified alkyd resin application research

摘要

Alkyd resin dispersions are used in the paint industry as the basis for the new generation of environmentally friendly gloss paints. This research based on two-component seed oil soybean oil and castor oil to synthesis high-efficiency modified alkyd resin. The experimental conditions are the mass ratio of soybean oil with castor oil is 2:1, 55% degree of oil, Ni(OH)_2 as the catalyst and 210°C～220°C for alcohol solution reaction, 220°C for esterification under the protection of nitrogen. The experimental results show that the product non-drying days are more than 30 days, acid value is 6.6, the migration is 1.2%, adhesion is one level, flexibility is 0.5, chroma value is 8.
