Development and Application of Long Acting Alkyd Resin
Firstly modified the alkyd resin by screening the types and dosages of vegetable oleic acids,poly basic acids,polyols and catalysts in the synthetic raw materials of resin,and then further modified the petroleum resin by grafting it to alkyd resin macromolecules with chemical grafting method,so as to improve the stability and artificial aging resistance of the coating.The prepared product conforms to various indicators of ready-mixed paint in GB/T 25251-2010 Alkyd Resin Coatings.
