Description
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of water dispersive alkyd resin synthesis technique.
Background technology
Synolac is a class oil modified polyester resin, and Synolac can be with melt phase polycondensation or solution polycondensation manufacture.Scorification is that glycerine, Tetra hydro Phthalic anhydride, lipid acid or oil are heated to more than 200 ℃ esterification in inert atmosphere, until acid number reaches requirement, then solubilizing agent dilution.Solution polycondensation is to react in dimethylbenzene equal solvent, and dimethylbenzene is solvent, and conduct and water azeotropic liquid, can improve speed of reaction again.Temperature of reaction is low compared with melt phase polycondensation, and product look shallow.The performance of resin is different with the structure of lipid acid or oil.Synolac is mainly as coating, paint, at aspects such as metal protection, furniture, vehicle, buildings, be widely used, also can be used as the insulation layer of enameled wire, make ink and be widely used in Printing industry, in addition also for the manufacture of moulded plastics, in the actual manufacturing, the water dispersible of common Synolac is also bad, and the storage time of this type of Synolac is lower, and hardness is not strong yet, production cost is relatively high
