Problems solved by technology

The usual alkyd resins are made by polymerizing vegetable oil or vegetable oleic acid with polyols and polyacids. The prepared coatings are generally dry. In recent years, in order to meet different performance requirements, many modified alkyd resin products have appeared, mainly including TDI (toluene diisocyanate), styrene, acrylic modified alkyd resin, such as "Modern Paint and Coating" 2002 03 issue discloses a kind of manufacture method of TDI modified alkyd resin, "Chemical Engineering" 2001 01 Issue, "Material Protection" 2000 08 and "Chemical Technology and Development" 2006 Volume 35 Issue 5 disclosed the production method of styrene-modified alkyd resin, "Journal of South China University of Technology" (Natural Science Edition) 2000 Issue 08 disclosed a method for synthesizing acrylic modified alkyd resin, etc. The dryness of the paint formulated with the modified alkyd resin synthesized by the above method is improved, but the product cost is increased to varying degrees
