High-Efficiency Modified Alkyd Resin Application Research
Abstract:
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.
