| titleOfInvention | A kind of highly filled hydroxy polyester resin and the preparation method and application thereof |
| abstract | The invention discloses a kind of highly filled hydroxy polyester resins and the preparation method and application thereof.Preparation method is：(1) small molecule polyol, polyether polyol, acid anhydrides and the solvent of formula ratio are added into reaction kettle, stirring is warming up to 90-110 DEG C of reaction 3-4h, until system is transparent；(2) epoxide and catalyst are added, 90-120 DEG C of reaction 4-12h is maintained the temperature at and waits for that acid value reaches 10mgKOH/g hereinafter, cooling discharge obtains highly filled hydroxy polyester resin.The resin solids reach 79% or more, viscosity 400-1900mPas.The hydroxy polyester resin preparation method is simple, and no coupling product generates, and of low cost, reaction condition is mild, is suitable for mass producing.Admittedly containing height, VOC content is low for the construction of the double-component polyurethane coating prepared using the hydroxy polyester resin, and hardness of film is high, richness is high, guarantor's light colour retention is good and medium-resistance is excellent. |
